The EEPROM registers a data set describing characteristics of the LEDs, where the data set contains an information about a maximum, measured luminous flux, measured light color, light wavelength, exactly measured spectrum of light and temperature-dependent behavior of the LEDs. An independent claim is also included for a device for controlling a lamp with two different colored LEDs.

Description

The Invention relates first a lamp according to the preamble of claim 1.

such Luminaires are known and widely used. They are by the applicant manufactured for decades.

The Invention particularly relates to an interior or exterior light, the one part of the building, one Building area or to illuminate or illuminate an object or in the manner of a Orientation lamp or decorative light can backlight a surface. Further In particular, the invention relates to such lights, which in the Preparation, i. factory, with at least one bulb stocked become.

From the German patent application DE 198 17 073 A1 the applicant, it is already known to combine several lights to a network of lights. This, a plurality of individually controllable lights having system comprises a control unit that can address the individual lights and this sends control commands or control information via a separate signal transmission line. In particular, it is provided in the lights of the prior art that each lamp has a single light source, that is, a single lamp that can be addressed by the transmitted via the signal lines control information, for example, to turn on or off to be dimmed to to blink. The like. In the event that the lamp has a plurality of bulbs of different colors, the control information can also cause a color change or control the light to achieve a color mixed overall light distribution.

The Invention relates in particular to a luminaire, which in a System or network of individually controllable lights is einbindbar and with other lights and with one or more controls or control units over a signal line is connectable.

Especially but not exclusively is the lamp according to the invention can be integrated into a network of luminaires that works according to the DALI protocol. DALI (digital addressable lighting interface) is a signal transmission protocol, the working group DALI at the Zentralverband der Elektrotechnik- and electronics industry.

Out the pre-published Manual DALI "AG DALI an activity of the operating committee in the ZVEI ", Richard-Pflaum-Verlag Munich, goes out a system for controlling a plurality of lights, in each lamp is assigned its own DALI ballast, which a Memory, in the address data and light scene information are writable. The lights connected to a DALI network are with the common control over the signal transmission line connected.

Another generic lamp is in the post-published German patent application DE 10 2005 009 228 the applicant described.

In the case, that several lights in the immediate vicinity, for example, next to each other, arranged are and, e.g. together an area illuminate or backlight areas in the immediate vicinity, urges an observer almost inevitably the colors and brightnesses emitted by the individual lamps, this means Light streams to compare. For example, a wall several meters long flooded by several trained as wallwasher lights, so Jump both color differences of the individual lights, as well Brightness differences, clear in the eye.

ever after, which illuminant or which illuminant the luminaire has, can already production-related variations in terms of the maximum potential Luminous flux of the bulb, in terms of the bulb generated light color, but also aging or temperature-related Color or brightness differences of the bulb occur. These are particularly noticeable when several in one lamp Lamps of different colors are arranged and a color mixture should be done.

Of the Invention is therefore based on the object, a lamp according to the preamble of claim 1 such that they have the opportunity offers to prevent the previously described disadvantages.

The invention solves this problem with the features of claim 1, in particular with those of the characterizing part, and is accordingly characterized in that the lamp has a memory, in a record is written that describes at least one property of this lamp.

The The principle of the invention is thus essentially the luminaire allocate a memory into which a record is written. The data record describes at least one property of this luminous means. For example, the property to be described may be the maximum Be luminous flux of this bulb. Especially in the case of a designed as LED bulb is in this context too Note that LED manufacturers offer lot sizes of LED's, even with the best quality and presorting vary between 70% and 100% in their maximum possible luminous flux. The maximum possible luminous flux is e.g. in particular determined by the wafer quality. That means, that a first LED of this lot size one 100% luminous flux and another, second LED of this lot size one Only 70 percent luminous flux is able to generate. Be this two LEDs same Color built into two different lights and would be one consideration the different high maximum luminous flux does not occur, so would the a luminaire with the first LED with maximum control in comprehensible Way a higher one Generate brightness as the other LED.

On the inventive way is the property of the bulb, so for example the maximum Luminous flux, in particular the measured, maximum possible luminous flux this illuminant, directly or as related information, have been written into a memory of the luminaire as a record. This record may be at later Control of the light source are taken into account, so that when the two lights with the two LEDs receive a control signal, maximum To emit brightness, that LED, which has a higher maximum Luminous flux can be dimmed by a factor of 70%, while the second LED, which only produces a 70% luminous flux can not be dimmed and generates its maximum luminous flux. That way you can Both luminaires produce an equal brightness, so that in total a smoother Impression can be evoked. The record therefore offers the Possibility, considering the property, in particular the measured property of the individual Bulb to make a correction.

Of the Data set is preferably written into the memory at the factory. This can be done, e.g. immediately after the maximum luminous flux has been measured or e.g. if the bulbs in the light is mounted. The memory may e.g. from a separate electronic Be provided, for example, a in the lamp existing operating device is connected upstream and which that from a controller over the signal line received signals in the manner of a repeater the operating device and thus further transmits to the bulb, which automatically a Correction under consideration the property of the bulb is made.

alternative The memory can also be connected from one to the signal line Control are read, the controller below the Readout the property of the respective bulb when driving considered the respective light. In this case, the memory, for example, from a operating equipment present in the luminaire, e.g. from a light scene store a DALI operating device provided be.

Equally, like LED's different maximum luminous flux can have can LED's as well vary in color and, for example, have wavelength differences of +/- 5 nm. Also this parameter can be determined as a measured value and as a property the illuminant in the form of a record in the memory inscribed become. In particular, if several bulbs different Are provided with the knowledge of the exact light color, which produces the light source, an optimized color mixture, so that several lights by a correspondingly intelligent control can cause an identical color impression.

Of the into the memory to be written record can be information about the contain exact light color of this bulb. Instead of a Specifying that the LED emits red color, for example now the exact wavelength of the red region, in particular the maximum of the emission spectrum this LED in the case of a trained as LED bulb in the memory can be entered. In particular, the measured Light color of the bulb is recorded as a record. In addition to the Exact light color can also be a spectrum, ie a spectral light distribution of the illuminant, written as a record in the memory become. The exact spectrum of the illuminant can be measured equally at the factory be, the spectra of the individual lamps, in particular at LED's, different fail can.

As a property of the bulb is in addition to information about the maximum luminous flux and / or information about the exact light color, for example, also a temperature-dependent behavior of the luminous means and / or an aging-dependent behavior of the luminous means. Both behaviors can refer both to the maximum permissible luminous flux and to a spectral change. The properties of light bulbs not only play a role in LEDs but also in other light sources, for example in OLEDs or optionally in fluorescent lamps. The invention thus relates to lights, regardless of which type is the existing light in the lamp.

The temperature dependence of the lamp can, for example, at different ambient temperatures or different chip temperatures, especially when using LED's as bulbs, play a role, where the chip temperature is also dependent on that up to this Time of the switched on duration of this LED. In the event that the light a sensor is associated, which can detect a temperature, for example an ambient temperature or a chip temperature, at least one the operation of the lamp influencing temperature, may result the storage of information about a temperature-dependent behavior the lighting means a corresponding correction or adjustment of the over Signal line obtained control information, in particular in the manner described above, for adaptation of a to be sent Luminous flux or to adapt a color mixture.

In the case, that the record contains information about age-related behavior of the illuminant contains it is advisable to assign to the memory a device which recorded the operating life of the bulb. This can be, for example in the manner of an operating hours counter take place, for example, in the case of LEDs as a light source not only the turn-on but also the inrush currents or more precisely, that done by LED's Work plays a role, but without further ado Electronics can be detected. Is the total operating time known? of the light source and the age-dependent behavior of the light source, which has an influence on a spectrum shift and / or on can show a maximum luminous flux, a corresponding Correction or adaptation take place.

If the light information about an age-dependent one Behavior of the bulb contains can also be advantageously provided, a control of the lamp considering of maximum permissible Operating temperatures or, e.g. in the case of LEDs, taking into account maximum allowable operating currents. Without this, e.g. Influence on The color-mixed total light distribution must have a control unit the maximum allowable Operating temperatures or the maximum allowable operating current automatically limit, and so increase the life of the bulbs.

Preferably the light is over the signal line connectable to a controller. It can work to trade one or more controllers.

Further Preferably, the controller communicates with the lamp via control signals according to the DALI protocol. This allows recourse to a widely used standard.

The Luminaire may have a memory containing a record or a memory in which several records are written or several memories in which several data records are arranged.

Of the or the memory can one or more records contain one or more properties of one or more Describe bulbs.

Preferably the lamp has a controllable by the controller operating device, in particular a DALI device, on. this makes possible the recourse on known components.

According to one In the first embodiment of the invention, the memory is arranged in the operating device, i. from the operating device provided. Here, for example, the memory of a anyway located in a DALI operating device Light scene memory be formed, so that on an existing Memory used can be. This memory is according to the invention factory with the record or with the records described the property or properties of the bulb or describe the bulb.

The data record located in the memory of the operating device can be transmitted by the controller via the signal line in an advantageous embodiment of the invention when the memory is read. Even if the memory is not in a control gear, but in a separate electronic construction is arranged, it can be provided that the memory can be read by the controller and the record via the signal line to the controller is transferable. The data record can be recognized and processed by the controller. The controller can then, upon receipt of the record, send control signals to the luminaire that take into account the property of the luminous means. This means that the controller transmits control information to the luminaire, in particular to an operating device contained in the luminaire, which are corrected or adapted on the basis of the now communicated properties of the luminous means.

Has For example, the controller obtained the information that a first light source of a first light a maximum possible Emit 100 percent luminous flux of a specific light color can and another bulb of another lamp of the same Light color emit only a 70 percent maximum possible luminous flux can, and is desired, that both lights provide uniform light with the maximum possible To generate brightness, the controller can go to the first Lamp send a signal, after which the existing, more powerful light source only to generate a 70% luminous flux and that in the second lamp included, weaker Light source is driven maximum, so that in consequence both Each with the two bulbs illuminate the same luminous flux to generate. Thus, for example, the desired uniform illuminance can be achieved become.

According to one advantageous embodiment of the invention uses the controller the record for a Correction of the control signals to be sent. This means that the Properties of the lamps from the controller before sending considered the control signals can be and in particular for the case that connected to the controller at least two bulbs are an adaptive correction based on the notified feature is made.

Of the Record can be read after reading, for example, in another Memory, e.g. is assigned to the controller, are stored. It is then no longer absolutely necessary to have the record in the Leave memory in the light so that this memory is overwritten can be.

Especially can be a reading of the memory and a transmission of the record to the controller as part of an initialization of a lighting network be carried out, wherein the controller in a recognition process in which For example, the luminaires are provided with individual addresses and information about the type of bulbs to be obtained, even the records that the property of the bulbs relate to be transferred.

According to one alternative second embodiment of the invention is the memory Part of a separate electronic component, with the operating device the signal line is connected. Such a separate electronic Component can be connected upstream of an operating device and thus between the operating device and the controller can be arranged. It can be the one from the controller received control signals for the operating device are determined, taking into account correct or adjust the data set and the adjusted control signals to the operating device send. The controller in this way does not notice at all that a component is present, which performs a correction of the transmitted control signals.

It there is also the possibility that the device is connected to several operating devices and of the Control receives control signals, the only for a control gear are determined. During execution a corresponding correction, and a corresponding connection wiring provided the device can receive the received control signals also corrected to different operating devices or forwarded adapted. The component has this preferably one or more memories in which different ones records inscribed different light sources. The different ones Illuminants are assigned to the different operating devices.

The Component can thus e.g. also intended only for a control gear Control signals received from the controller, taking into account the different records correct differently and adapt differently, and the send different adapted control signals to the several operating devices. In this way, the device several lights in the manner of a Sub-system within a network of luminaires, e.g. within a DALI network, manage.

According to one further advantageous embodiment of the invention, the lamp at least two bulbs of different colors, individually from a controller to achieve a color mixed total light distribution are responsive. More preferably, each bulb is a Record associated with the property of the associated bulb describes.

These Embodiment of the invention allows a color-mixable light, for example, a red, a green and contains a blue bulb or alternatively in addition still contains a cyan and an amber bulb or alternatively also altogether only two differently white formed Contains bulbs, to mix different whites. In the simplest case one one red, one green and a blue LED containing light, the three LEDs can be on the previously described Be measured in the manufacture of the lamp, wherein their maximum possible light streams and their exact, exact light colors in the form of the in the memory or stored in the memories contained record.

in the Trap one red, one green and a lamp comprising blue LED is typically one called RGB ballast, So a control gear, which all three LEDs together, available. This operating device can now a component upstream, which contains a memory in which the records, describing the characteristics of the different three bulbs, are stored.

Receives the component from the control a control signal, after which the light a certain To produce color, e.g. a yellow color mix, the device can in knowledge of the properties of the bulbs a corresponding Make adjustments and mix colors or less colors strongly switch on, so that in total exactly the desired shade is reached.

The The invention further relates to a luminaire according to the preamble of the claim 32nd

A Such a lamp is known and has long been by the applicant Time made.

As previously described, exists at least in some bulbs in principle the problem that these are in terms of their exact color values and their maximum luminous fluxes differ. Although a red LED basically produces red Light. The exact light color can be quite a few nanometers vary, which is usually production-related and practically not is to be avoided. Even with other colored bulbs, e.g. blue LEDs, green LEDs or other light sources, such. OLEDs (organic LEDs) and other bulbs, such deviations the exact color values and also the maximum lumen output, i. of the maximum luminous flux, occur.

While the Deviations of the exact color values of the individual illuminants relative unproblematic if it is a monochromatic light is, exists in lights, the color mixed light, ie To mix light colors, the problem is that the desired hue often not exactly hit. Especially if several lights immediately spatially are assigned to each other and generate an identical color of light should, can Color deviations of the mixed colors arise.

Of the Invention is therefore based on the object, a lamp according to the preamble of claim 32 in such a way that a higher color fastness, i.e. a higher one Color rendering is reachable.

The Invention solves this object with the features of claim 32 and is accordingly characterized in that the luminaire has a memory in which a data record contains information about the exact color values of the individual lamps and / or containing information about the maximum luminous fluxes the individual illuminant is written, wherein a correction device is provided, which controls the signals taking into account the exact color values and / or the maximum luminous fluxes corrected and a control of the individual bulbs with corrected Makes control signals.

The exact color values and / or the maximum luminous flux can be immediate or in the form of a dataset containing this information, at the factory be inscribed in the memory. The registration process can preceded by a measuring operation, the factory, the exact color value, So for example, the exact, emitted by the individual LED wavelength and / or measures the maximum luminous flux.

A Correction device may be aware of the record an adjustment and correct the control signals so that the drive the individual light source is made in a corrected manner. With that you can exact mixed colors, i. generated color mixed light distributions which correspond exactly to the color blend value that is desired.

As an exact color value while a measured color value is considered in the context of the invention be takes into account that a color specification, such as red or blue, is much too inaccurate. As an exact color value, for example, a wavelength specification in nanometers is considered, which is itself subject to a measurement accuracy of, for example, +/- 1 nm when measuring the wavelength, but in the result represents a much more accurate indication than the mere color red or green or blue.

The Correction device can be part of an electronic component be, which is preferably arranged in the lamp. The correction device can process the record automatically and that way the information about take into account the exact color values and the maximum luminous fluxes.

According to one advantageous embodiment of the invention, the correction device Also part of a control gear for at least one light source be. So a control gear, For example, an electronic ballast, for the light source, which If necessary, it is also possible to control a plurality of illuminants, a corresponding one electrical module, for example, a μ-processor, containing the Correction device and a correction of the on the lamp incoming control signal for controlling the lamps automatically can make.

Especially if an operating device has a own controller has, This controller can also represent the correction device and take over the correction function.

at An alternative embodiment of the invention is the correction device assigned to the controller so that from the controller via a Signal line sent to the lamp control signals the lamp already in a corrected way, because the correction in the controller is made.

The The invention further relates to a luminaire according to the preamble of claim 37 and in turn is based on a lamp according to the preamble of claim 32, as disclosed by the Applicant Previous use has become known.

This Invention is based on the object, a lamp according to the preamble of claim 37 in such a way that in a simple manner exact mixed colors can be generated.

The Invention solves this object with the features of claim 37, in particular with those of the license plate part, and is accordingly characterized in that the luminaire has a memory in which a data record containing information about the exact color values of the individual lamps and / or containing information about the maximum luminous fluxes the individual illuminant is written, wherein a device intended for the production of color mixed light distributions is that a certain, exact mixed color by controlling the considering individual lamps the exact color values and / or the maximum luminous fluxes generated.

The The principle of the invention is essentially that a device intended for the production of color mixed light distributions is that a certain, exact mixed color by controlling the generated individual light source, the exact color values of the considered individual illuminant and / or their maximum luminous flux become. The exact color values and the maximum luminous fluxes will be directly or as a record containing the exact color values and / or the luminous fluxes the individual illuminant describes, in a memory of the lamp enrolled. For this, the exact color values and / or the light streams the individual bulbs previously measured. The memory is typically factory-made described.

The Device for producing color-mixed light distributions can access this record. This makes exact mixed colors possible.

The Device for producing color mixed light distributions can be arranged in the luminaire or part of a with the Light over be a signal line connected control.

In the event that this device is associated with the lamp, there is a particular advantage if the lamp has a memory in which a record is stored with information about several, available for selection, exact mixed colors. This embodiment of the invention, by arranging this memory, which may be a separate memory or uses a same memory space as the dataset, allows for recourse to a plurality of previously defined exact mixing colors from which one or more exact mixing colors can be selected and generated by the device can be. Im simple In this case, the luminaire has a memory in which besides the dataset a number of previously defined, ie factory-defined, exact mixing colors is arranged, wherein an adjusting device can be provided, for example in the manner of a rotary switch, in particular in the manner of a color potentiometer, which has an adjustment the predefined colors. According to the invention, the predefined colors are exact mixed colors, ie they take into account the exact color values and / or luminous fluxes of the individual luminous means which have previously been obtained by measurement.

The The invention further relates to a device for controlling at least one lamp according to the preamble of claim 40. In particular, this invention relates to a device for controlling at least one lamp according to claims 1 to 39th

The Invention is based on a control device, as by obvious prior use of the applicant has become known.

task The invention is a device according to the preamble of the claim 40 such educate that they a simplified control the lights to achieve a color mixed total light distribution the lamp offers.

The Invention solves This object with the features of claim 40, in particular with those of the license plate part, and is accordingly characterized in that the device taking into account information about the exact color values and / or the maximum luminous fluxes of the individual Illuminant displays an achievable by the lamp color space.

The The principle of the invention is first that the exact Color values and / or the maximum luminous fluxes of the lamps of the luminaire detected, i. be measured and communicated to the device. This can be done, for example, as explained above, according to which the luminaire has a memory containing in the records Information entered the exact color values and / or the maximum luminous fluxes are. The device can, in particular via a signal line, the the device with the light connects, the exact color values and / or the maximum luminous fluxes or read a record describing these values and below consider. The device can information about the exact color values and luminous fluxes in principle, too be made known in another way.

There the device the exact color values and luminous fluxes of the individual Light source knows, they can be reached by the light Show color space. A color space achievable by the luminaire provides a group of color mixed total light distributions, ie Several different colors are actually accessible from this luminaire are. While theoretically by mixing light from a red, a green and a a blue bulb virtually all colors in infinity Fine graduations can be mixed, it can be at a real Lamp due to the exact color values and the maximum luminous fluxes of the individual Illuminant only possible be a subset of all possible ones To achieve colors. The actual achievable color space is thus at an infinitely fine, gradual Activation possibly although infinitely large, but still smaller than a theoretically possible color space that does not exact color values and maximum luminous fluxes of the lamps are considered.

The Device actually shows that achievable color space, for example in the form of a standard color chart, as a color wheel, as a color palette or as another diagram, which the selection of colors allows comfortable. Of importance is that of an operator or a user of the device only the colors are displayed, which the device actually too can produce real, with a high color fastness is achieved since the displayed color, for example, on a screen of the Device is displayed, in fact also exactly and identically corresponds to the color that the light as produce color mixed overall light distribution.

Thereby, that the user is immediately displayed which actual Colors are available the choice of colors can be made easier.

According to an advantageous embodiment of the invention, the device contains information about a sub-color space, which represents a real subset of the achievable color space. This embodiment of the invention provides that a sub-color space, ie a sub-group of the group of actually achievable colors of the luminaire is formed. This sub-color space is a true subset of the achievable color space and can be displayed to the user. For example, the sub-color space contains colors for special color create moods. The user can access this sub-color space directly. This makes sense, for example, if an operator would like to allow only very specific color ranges, such as pastel tones or favorite colors, or those mixed colors that are typical for the operator of the device, eg corporate identity colors or the like. Also, special colors, the to match certain color moods are achieved.

Under color spaces are especially advantageous if in certain application areas certain, special shades required are, for example in the shop lighting, where it is also on color fastness arrives to allow a customer to wear a garment in a particular color considered, not surprised This is when this garment is under daylight outside of the shop area in a different color. Also for simulation certain color situations, for example in connection with cosmetics advice od. Like., The definition of a particular sub-color space and the display option of a Under color space as advantageous represent.

Further Advantageously, it can be provided that the sub-color space according to Art a template is projected onto the accessible color space is. Such a template can, for example, a continuous curve or a plane Range that can be reached by the display device on the entire Color space projected with is displayed, preferably in an overlapping one Presentation. this makes possible in particular a lighting planner a quick overview of the relationship of the Under color space to the achievable color space.

Further Advantageously, the device may comprise a memory having a Group of several underground spaces having. From this group can further advantageously by an operator a certain sub-color space are selected. This allows a factory definition of certain sub-color spaces, which is a comfortable setting color mixed total light distributions by an operator, for example, by a lighting designer after mounting the device allow on site and a uniform lighting situation, for example at different locations of a company, achieving allow identical colors.

Finally, concerns the invention also a light source for a lamp according to the preamble of claim 46.

One Such bulbs for a lamp is known and widely used and can be used, for example, by a fluorescent lamp, an LED or any other Be formed bulb. The illuminant is intended for use in a lamp and is this, for example, within a lamp housing, or mounted on a lamp.

The The object of the invention is the known lighting means according to the preamble of claim 1 such that an improved Control of the bulb possible becomes.

The Invention solves This object with the features of claim 46, in particular with those of the license plate part, and is accordingly characterized in that the lamp is associated with a memory in which a record is writable.

The The principle of the invention is thus essentially the lighting means allocate a memory. This means that the memory is immediate can be arranged or attached to the light source. For example the memory can be arranged on a structural unit that carries the light source be, e.g. on a mounting plate, a circuit board or on a socket body for the bulb. Alternatively, the memory may be separate from the light source disk also detachable be arranged relative to the lighting means. For example, can be a disk, like CD-ROM, RFID (radio frequency identifying-tag) or the like, when buying a Bulb included with this.

Of the Memory is preferably an electronic memory containing a Contains record, which describes a property of the luminous means. Preferably is stored as a record a property of the bulb, the one maximum allowed Luminous flux of the bulb describes or / and an exact color value, this means a precise name of the emitted by the bulb during operation Color value or a color spectrum. Alternatively or additionally, too information about an age-dependent Behavior or a temperature-dependent Behavior of the bulb to be written into the memory.

In the case, that the memory is directly associated with the lamp and For example, part of a lamp-carrying unit, e.g. a board, for example, the memory can after mounting of the lamp, or the unit, in the light, read out become. The readout can either by a present in the lamp electronic component carried out and / or by a controller, the over with the light a signal line is connected to be performed. The reading of the record allows the lamp, or the controller, a correction of control signals to perform and the advantages described above, in connection with a Luminaire or described with a device for controlling lights have been alike to reach. The lighting means can also be a correction device be assigned, taking into account the record performs a correction of received control signals.

Incidentally understand the claims related to a bulb 46 to 57 at best considering the statements made above, so as to avoid repetition and also for the purpose of Reference to single or multiple characteristics to the corresponding ones Referenced text passages.

noted be that the proposed memory associated with a light source is to provide the previously described memory of a lamp can or can replace or supplement this. In the case, that the lamp has a memory which is separate from the Memory of the light source is arranged, offers a transmission the memory contents of the lamp memory on the memory the light on. For the case that the memory of the bulb in the light represents or replaces existing memory is not over the Memory of the bulb addition, further memory required.

The Lamp according to the invention allows on the one hand a simplified factory assembly, as a measurement the properties of the bulb in the manufacture of the lamp can be omitted and already made by the lighting manufacturer can be. Thereby can Steps in the lighting manufacturer omitted, because only still the reading of the memory of the bulb must be performed. On the other hand allows the illuminant according to the invention also an unproblematic replacement bulbs defective bulbs a luminaire according to claims 1 to 39, so that a replacement bulb associated with a memory that is, a record containing information about properties of the luminous means, this data set for the previously described color compensation or color correction available can make.

The lamp 10 has, preferably within a light housing, not shown, a lighting means 13 , a control gear 14 for the light source 13 and an electronic component 15 on.

The signal line 11 is about a section 16 with the separate electronic component 15 connected. The component 15 is about a section 17 a control line with the operating device 14 connected, and the operating device 14 is over a line eighteen with the bulb 13 connected.

The operating device 14 is in the embodiment of 1 a DALI operating device, that is to say a device meeting the requirements of the DALI protocol. It should be noted that any other operating devices can be used.

A power supply line 19 supplies the luminaires with an operating voltage of eg 230 V. 1 For the sake of simplicity, only a portion of the power supply line is shown 19 who is the light 10 supplied, and it becomes clear that the controller 12 , the lamp 10b and other lights, not shown, preferably together to the power supply line 19 are connected.

Inside the lamp 10 provides a first section 20 the power supply line 19 the operating device 14 with operating voltage. The administration eighteen that the operating device 14 with the bulb 13 connects, provides the light source 13 with operating voltage, the voltage supply of the bulb 13 in a controlled manner by the operating device 14 he follows.

Another section 21 the power supply line can also be the electronic component 15 supply with operating voltage.

In an embodiment of the invention, not shown, a power supply of the separate electronic component 15 also via the operating device 14 take place, so that in this case the line section 21 could be omitted and a line from the control gear 14 to the component 15 would be lost.

Alternatively, there is also the possibility of the component 15 to supply with an operating voltage, the the component 15 directly from the via the signal line 11 respectively. 16 received control signal receives. In this case, the arrangement of an accumulator in the device is recommended 15 , to store the energy.

In accordance with the invention, the device 15 a memory 22 on that in 1 is shown only schematically. This store 22 , eg an EEPROM, is described with a data set which is a property of the illuminant 13 describes, in particular a measured value of a parameter of the luminous means 13 contains.

In particular, the memory contains 22 an information about the maximum luminous flux that the bulb 13 can emit. Alternatively or additionally, the memory contains 22 an information about the exact color that the bulbs 13 emitted and which is also present as a measured value. Both measured values are factory-made during the manufacture of the luminaire 10 in the store 22 enrolled. This information is the electronic component 15 now as the basis for a correction or adjustment of the control signals available to the device 15 from the controller 12 contains.

It should be noted that the component 15 the operating device 14 upstream. The control 12 who, for example, is not informed that the light 10 a separate component 15 has, believes, their control information or control signals directly to the operating device 14 to send.

Is in the store 22 For example, the information inscribed that the bulb 13 can produce a maximum luminous flux of 70%, this information can be used for a correction of the signal, which is described below. First, however, it should be noted that the second lamp 10b according to 1 a second light source 13b which is now believed to have the same color as the illuminant 13 in the light 10 , The two bulbs 13 . 13b should also emit, for example, blue light. The light source 13b but can produce a maximum luminous flux that is 100%. This information about the maximum luminous flux is in the memory 22b of the electronic component 15b the light 10b stored.

Get the two lights 10 . 10b now from the controller 12 the signal to produce a maximum luminous flux of 100%, so can a different control of the two bulbs 13 and 13b done though the controller 12 to both lights 10 . 10b sends identical brightness values, that is, control commands that are to cause the bulbs to output a maximum luminous flux.

The electronic component 15 the light 10 can considering the record of the memory 22 now notice that the bulbs 13 can only deliver a maximum luminous flux of 70%, which represents the lower limit of a tolerance range of different maximum luminous fluxes, ie a minimum current. The electronic component 15 is therefore the input at the input control signal from the controller 12 in the simplest case uncorrected to the operating device 14 forward, leaving the associated light source 13 receives the information to generate a maximum luminous flux, due to the technical characteristics of the bulb 13 as described is 70%.

The electronic component 15b the light 10b can by resorting to the record in memory 22b notice that the bulbs 13b can emit a 100 percent luminous flux and knows that a correction of the control unit 12 contained signal in the sense of damping or dimming. Equally, the electronic component knows 15b that a dimming by a factor of 0.7 or 70% must be made in comparison to the other lamps 10 identical luminous flux of the illuminant 13b to be able to generate. Accordingly, the electronic component takes 15b a correction of the received control signal before and sends to the operating device 14b a correspondingly corrected control signal via the signal line section 17b so that the operating device 14b the bulb 13b only dimmed controls and the light source 13b finally emitted only a 70 percent luminous flux.

The previous description clarifies that the electronic component 15 . 15b or optionally a correction device arranged there 24 the from the controller 12 corrected control signals corrected. The correction or adjustment of the control signals takes place in consideration of the memory 22 respectively. 22b contained record. Different components 15 . 15b take, because the different bulbs 13 . 13b have different characteristics, also different corrections.

The function of the component 15 . 15b can therefore also be regarded as that of a converter, that is to say of a repeater, with correction function. The records remain in the associated memories 22 . 22b For example, permanently inscribed, so the lights 10 . 10b also from the signal line 11 can be solved and connected to another controller, for example, without this information is lost.

A significant advantage of this embodiment is that the controller 12 does not recognize that the data sets are used to correct the control signals. This allows the lights according to the invention 10 . 10b also to any other controls 12 , according to the same protocol, eg according to the DALI protocol, control signals to the signal line 11 be modulated, connected and still the advantages of the invention can be achieved.

In an alternative embodiment of the invention, the controller 12 the memory contents of the memory 22 . 22b read out the corresponding records via the signal line 11 can be transmitted. The control 12 can access these data records and process the data records, for example, to indicate to an operator which technical properties the connected lamps have.

Finally, there is also the possibility that the headquarters 12 taking into account the transmitted data records from the memories 22 and 22b self-corrected signals to the lights 10 . 10b sends. In this case, the electronic components may 15 . 15b but make no further correction of the control signals obtained, since the different components 15 . 15b in this case already received different, corrected control signals. Accordingly, there is the possibility of the electronic components 15 . 15b such that they, if the contents of the memory 22 . 22b from a controller 12 has been read once, suppress the correction function or switch off and the incoming signals unchanged to the operating device 14 hand off.

In the previously described embodiment of 1 was assumed that the electronic component 15 one of one in the light 10 contained operating device 14 is separate component. The embodiment of 2 but now it should make clear that the memory 22 not necessarily of a separate component 15 must be provided.

2 shows in a representation similar 1 a schematic block diagram, with two lights 10c and 10d , each one a light source 13c respectively. 13d which has a voltage supply line section 18c respectively. 18d with an associated control gear 14c respectively. 14d connected is. The respective operating device is via a signal line section 16c respectively. 16d with the signal line 11 connected to the lights 10c respectively. 10d with a controller 12 combines.

On the structure of the power supply line 19 according to 1 is in 2 not detailed. The viewer of the 2 However, it becomes clear that a comparable power supply of the lights 10c . 10d is provided, where there for the sake of clarity, only the signal line 11 is shown.

The memory in which the record is inscribed, which is a property of the associated illuminant 13c respectively. 13d describes is now a memory 22c respectively. 22d of the existing operating device 14c respectively. 14d , The operating device 14c . 14d is a DALI operating device which has a light scene memory as defined by the DALI protocol. This can be described, for example, with the data record. Others, in the control gear 14c respectively. 14d Existing memories can be described with the data record or with the data records.

In contrast to the embodiment of 1 takes in the embodiment of 2 no correction from the controller 12 obtained control information in the light 10c respectively. 10d instead of. Instead, after connecting the lights 10c respectively. 10d to the signal line 11 from the controller 12 as part of an initialization or in a subsequent process step, the memory contents of the memory 22c or 22d and the data set or records to the controller 12 transfer. The control 12 can subsequently, taking into account the records corrected control information to the individual lights 10c respectively. 10d send, so that's the basis 1 described goal, for example, a uniform brightness of the different lights 10c . 10d , is achieved in an analogous way.

3 shows a further embodiment of a lamp according to the invention 10e in a schematic tables, block diagram representation, comparable 1 , Again, a separate electronic component with 15e denotes a memory 22e having. The lamp is also an operating device 14e arranged, to which three different bulbs 13e1 . 13e2 and 13e3 are connected, for example, of a red LED, a green LED and a blue LED are formed. The operating device 14e For example, it may be a conventional RGB DALI driver for three LED's.

The operating device 14e and the electronic component 15e be about sections 20 and 21 a power supply line 19 supplied with operating voltage. The electronic component 15e is analog 1 over a section 16 with the signal line 11 and above with a controller 12 connected. Comparable lights 10e ' and 10e '' are also connected to the signal line 11 connected.

In the store 22e of the electronic component 15e are stored one or more records, in place of or in addition to the maximum luminous flux of each bulb 13e1 . 13e2 . 133 also the exact color values of the bulbs 13e1 . 13e2 and 13e3 can be measured, for example, in the form of the wavelength actually emitted by these lamps in nanometers. For example, in the manufacture of the lamp 10e be found that the blue bulb 13e3 a wavelength le3 that the green light source 13e2 has a wavelength le2 and that red bulbs 13e1 has a wavelength le ₁ .

In the 3 not shown red, green and blue bulbs of the light 10e ' For example, they may emit different wavelengths, which may differ from the wavelengths le3, le2 and le1.

For example, LEDs of green color may vary between 505 nm and 515 nm, this value being merely exemplary. While the green LED 13e1 the light 10e For example, emitting green light of wavelength 515 nm, the corresponding, in 3 not shown green LED of the lamp 10e ' emit green light of wavelength 505 nm. The lamp 10e ' and more lights connected to the same signal line 11 can in turn produce slightly different green values.

Likewise, too the red and blue LEDs have different values. After all, lights can do the same colored bulbs, for example next to a red, a green and a blue LED also a white or / and a yellow LED and / or have a cyan and / or an amber LED, vary accordingly.

While the color variations are less problematic when only monochromatic luminaires are considered, even such small color differences on the order of magnitude of individual nanometers and deviations in the maximum luminous flux become noticeable to a greater extent when color mixtures occur, as is the case with luminaires 3 possible are.

Will the light 10e for example, from the controller 12 over the signal line 11 so controlled that the light 10e To produce a mixed tone of a particular color, so obtained in a conventional control 12 the lamp 10e a correspondingly composed signal, which is sent to the operating device 14e is sent and causes the three bulbs 13e1 . 13e2 and 13e3 be controlled accordingly. Shall the lights 10e ' and 10e '' produce same color, get these lights from the controller 12 an identical drive signal.

In the lamp according to the invention 10e according to 3 is in the store 22e of the component 15e a record is stored showing the exact light color and the maximum luminous fluxes of each light source 13e1 . 13e2 . 13e3 describes. This can either be an immediate information of the light colors and luminous fluxes actually emitted by the individual illuminants. Alternatively, however, this information may be expressed as a deviation from a standard value, or in an alternative manner in the form of a correction factor.

Receives the light 10e now for example by the controller 12 the signal to produce a certain mixed color, so can the electronic component 15e knowing the exact color values and the maximum luminous flux of the three lamps 13e1 . 13e2 . 13e3 make a correction of the control signals obtained and the three bulbs 13e1 . 13e2 . 13e3 via the operating device 14e in a corrected way, so that the bulbs 13e1 . 13e2 . 13e3 together as a result of the corrected control exactly the light color generated by the controller 12 was intended to produce.

In this way, despite different color values and different maximum luminous fluxes in the three luminaires 10e . 10e ' . 10e '' light sources succeed that the three different lights actually emit the same color light.

The exact mechanism of the correction using a correction matrix will be explained below. At this point, but already noted that the light 10e according to 3 an electronic component 15e shows in addition to the memory in addition 22e a separate building block 24e is arranged, which represents a correction device. This correction device, which controls the signals that the light 10e from the controller 12 receives, so that subsequently a forwarding of the corrected values to the operating device 14 can be made of a separate electronic component and in particular contain a μ-processor. Alternatively, the memory can 22e and the correction device 24e but also from a common component 15e , as in 3 shown to be formed.

In addition it is noted that also in 1 a corresponding correction device 24 is shown, it is clear to those skilled in the art that such a correction device can also be used in all other illustrated and not shown embodiments.

However, it should first be noted that a correction by the electronic component 15e For example, then can be done if by the controller 12 over the signal line 11 to the light 10e For example, only the signal is transmitted that the light 10e to generate red light. Corresponds to that of the bulb 13e1 emitted light color is not exactly the desired light, but varies, for example, by a few nanometers, so can by adding small green or blue light components through the bulbs 13e2 respectively. 13e3 also a correction of this light done.

It should be noted that 3 an embodiment shows which with a separate electronic component 15e by type of in 1 illustrated embodiment with an electronic component 15 is working. In analogy to 2 but it can also be with a light 10e with several bulbs 13e1 . 13e2 . 13e3 different color the function of the memory 22e in the operating device 14e to be incorporated. Such an embodiment is not shown for reasons of clarity.

Similarly, the memory can 22e of the electronic component 15e also from the controller 12 be formed readable, wherein in the case of a readout and transmission of the record in turn, the correction function of the electronic component 15e should be turned off.

3 also shows a sensor 23 for detecting a temperature. For example, the ambient temperature of the luminaire 10e Alternatively, however, for example, a chip temperature of the LED chip are measured. Finally, it is also possible, different temperatures of the individual bulbs 13e1 . 13e2 . 13e3 to eat.

Since it is known that the ambient or operating temperature of the individual lighting means, in particular in the case of LEDs as lighting means, influences the operation of the LED itself, knowledge of the existing temperature of the lighting means can also be used to correct or adapt the control of this lighting means. This can be done in the memory 22e Also, a record can be stored, the temperature-dependent behavior of the individual bulbs 13e1 . 13e2 . 13e3 describes. Since often the exact operating temperature can not be determined, but this temperature results to a certain extent also from the currents flowing through the LED before the measurement time or from the current load in combination with the ambient temperature, the electronic component can 15e Also be associated with a device that the current or previously in the last moments, for example, in the last 30 s or 60 s done controlling the different bulbs 13e1 . 13e2 . 13e3 taken into account, it being possible to deduce the current temperature in the knowledge of the current or the last activation and that in the memory 22e stored temperature-dependent behavior of the individual lamps can be taken into account in a correction of the control signals in an optimized manner.

One or more temperature sensors 23 can also be used in the same way in the other embodiments.

Finally, it is also possible to have an operating hours counter in the electronic component 15e provide that, so to speak, which illuminant of the associated lamp (eg 10e ) in which way is charged. The memory 22e can contain a further record for this, which is the age-dependent Behavior of the individual bulbs knows. A correction by the device 15e can now be done in such a way that in knowledge of the hours of operation of the individual lamps an adaptation of the control 12 over the signal line 11 obtained signals and corrected control signals from the electronic component 15e to the operating device 14e be forwarded.

In Knowledge of the temperature-dependent Behavior of the bulbs and / or in knowledge of the age-related Behavior of the bulbs can also vary over different temperature ranges and / or over ensures a very long period of high color fastness of the lamp become.

Likewise, in embodiments not shown, it may also be provided that the data sets relating to the temperature-dependent and aging-dependent behavior of the lighting means via the signal line 11 to the controller 12 be transferred and this memory 22e is read out.

It can also be provided that in the controller 12 already contains a data set on the temperature-dependent or aging-dependent behavior of the lamps and, for example, in the context of an initialization process, the controller 12 from the lights (eg 10e ) is only informed which lamps are included in the lamp.

3 further reveals that in the electronic component 15e another store 25e is arranged. This store 25e serves to record a mixed data set, ie information about several, available for selection, exact mixed colors. As exact mixed color such a color is referred to, which results from mixing of the colors generated by the individual bulbs, this mixture taking into account the exact color values and / or the maximum luminous fluxes of the individual bulbs 13e1 . 13e2 . 13e3 he follows. Exact mixed colors, or a mixed data set that contains several of these exact mixed colors, are stored in the memory at the factory 25e enrolled. A selection can be made, for example, via a schematic, in 3 With 26 designated device, which may be formed, for example, in the manner of a Farbpotentiometers and, for example, can provide 12 adjustable colors. Also push button od. Like. Can be provided.

The advantage of such a device 26 for setting an exact mixed color is that several different lights can contain the same mixed data sets, so that taking into account the different exact color values and the different maximum luminous flux of the different bulbs of the different lights a user easily gets the opportunity to several lights one to produce identical exact light color.

The skilled person will appreciate that the memory 25e and the memory 22e may also be formed by a common memory.

Similarly, it becomes clear that the device 26 to set a mixed color together with the memories 22e and 25e and optionally together with the correction device 24e and any further, not shown devices of the device 15e represents a device for producing color mixed light distributions.

The device 26 may be under the control 12 be addressed, alternatively, but also be manually adjustable and produce the desired, exact mixed color, without the need for a control signal of a controller 12 requirement.

Advantageously, it contains in the memory 22 . 22b . 22c . 22e inscribed record information about both the maximum luminous flux as well as the exact color value. Depending on the type of light in the lamp 10 arranged illuminant, but it may also be sufficient to write into the memory information about only one of the two details. For example, an indication of the exact color value is sufficient if the illuminant in question varies greatly with regard to the color value, but only varies very slightly with respect to the maximum luminous flux.

in the reversed case, that is, if a strong variation of the luminous flux at the different LEDs but this is practically not in terms of their color value vary, it may be enough to write to the memory a record containing only information about the maximum possible Luminous flux contains.

Finally, different bulbs, depending on their nature, may also have different colors Give age-dependent and temperature-dependent behavior. If this behavior has a strong effect on the luminous flux or on the exact color value, it is advisable to include information on this behavior in the data record or to take this behavior into consideration when correcting the actuation signals. If the temperature-dependent or aging-dependent behavior practically has no effect on luminous flux and color value, this behavior can be disregarded.

Based on the representation according to 4 will now be another embodiment of a lamp according to the invention 10f be explained:
4 shows a lamp 10f connected in a conventional manner to a common signal line 11 is connected, with comparable representation according to 2 the associated power supply line is omitted for clarity. The lamp 10f consists of two partial lights 10f1 and 10f2 , each having three colored bulbs. The partial light 10f1 holds a red bulb 13f11 , a green bulb 13f12 and a blue bulb 13f13 , The bulbs can be the same as the three bulbs 13f21 . 13f22 and 13f23 the second part light 10f2 be formed by LEDs.

Every partial light 10f1 . 10f2 contains its own operating device 14f1 respectively. 14f2 which may be, for example, a DALI RGB ballast.

The special feature of this lamp 10f consists now in that for both partial lights 10f1 . 10f2 , which may also be arranged separately, ie, for example, distanced from each other, a common electronic component 15f is provided, which is a memory 22f having. In the store 22f is a record that contains the characteristics of different bulbs 13f11 . 13f12 . 13f13 . 13f21 . 13f22 . 13f23 the different part lights 10f1 and 10f2 contains and contains, for example, the exact color values and / or the maximum luminous fluxes of the individual bulbs. The electronic component 15f can also have its own DALI address and so from the controller 12 be recognized as a separate participant. In this case, the device 15f like a conventional DALI operating device from the controller 12 be responsive. The electronic component 15f but has the peculiarity that it is the one of the controller 12 contained control signals not simply forwarded, but corrected to both operating devices 14f1 and 14f2 the two part lights 10f1 and 10f2 retransmits. The correction is dependent on the illuminant and is typically different for the two sets of bulbs in the two part lights 10f1 and 10f2 ,

Receives the electronic component 15f from the controller 12 For example, a control signal, according to which a specific light color is to be generated, as a result of an individual correction and adaptation to the actual exact color values and maximum luminous fluxes of the individual luminous means of the two partial luminaires 10f1 and 10f2 a corresponding forwarding of the corrected control signals to the operating devices 14f1 and 14f2 done so that the two different part lights 10f1 and 10f2 actually produce exactly the same light color. The electronic component 15f can also have several operating devices 14f1 . 14f2 address or manage, so that the output side of the device 15f practically a sub-system of a DALI network can connect. As the electronic component 15f In the DALI network has only one address, this way, a very large number of lights without a component 15f limited to only 64 subscribers in the DALI network.

Such an arrangement, according to which an electronic component 15f while saving DALI addresses in the overall DALI network and supplying multiple operating devices 14f1 . 14f2 is used, but is particularly advantageous if the electronic component 15f Ensures that the bulbs of the individual part lights 10f1 and 10f2 to generate essentially the same light color.

4 also shows that the device 15f with two or more different temperature sensors 23f1 and 23f2 equipped, which measure the different temperatures and take into account in detail. In this respect, a correction due to the temperature-dependent behavior of the individual lamps in the manner described above can take place.

5 first shows a standard color chart, as known to those skilled in the field of lighting technology and as described for example in the manual for lighting, Lange, publishers; German Photometric Society, 4th edition, 1996, I. page 16 is shown and explained.

Without the basic principle of a standard color chart, which is assumed to be known, to be explained at this point, it is indicated that the standard color chart represents a substantially triangular area which is approximately in the right corner area 27 red color, in the lower left edge area 28 blue color and in egg nem upper edge area 29 green color. A central area 30 contains essentially white light. The unspecified intermediate areas contain mixed colors that result from mixing of the individual primary colors.

The Standard color chart shows all theoretically possible Colors of an ideal light with three ideal bulbs.

A real blue light source, for example a blue LED of a luminaire, emits, as stated above, different exact color values. The in the area 28 of the 5 indicated crosses 31 represent a group of measurement points that have been measured on different blue LEDs, as they are typically supplied by the LED manufacturer to a lighting manufacturer. Since these measured values lie in different places in the color triangle of the standard color chart, it is also not possible to mix the entire color space of the color chart according to the area by mixing with light from a red, a green LED, which are likewise present in the same luminaire and differing equally 32 be achieved, but only a limited, in 5 exemplarily triangular indicated accessible color space 33 , The achievable color space is therefore significantly limited compared to the theoretically possible color space. This achievable color space 33 is different for each lamp due to the different color values of the individual luminaire and represents the totality of the color mixed total light distributions actually achievable by the luminaire.

The device 12 for controlling, in particular, a plurality of luminaires 10e according to 3 or other lights now has in one embodiment, a display device which in the 6 and 7 in their entirety with 34 is designated. Shown in the 6 and 7 only the content of the ad. The display in the manner of a standard color chart was chosen here by way of example again, with other color space representations, for example color circles, color palettes or the like, being possible.

6 shows that the display device, for example in the form of a computer screen, the actually achievable color space 33 represents the associated lamp. In the event that to the device 12 to control a plurality of lights different lights are connected, the device 12 Under certain circumstances also make a comparative consideration of the different achievable color spaces of the individual lights, and find the lowest common denominator, ie the actually achievable color space 33 all to the controller 12 can reach connected lights. This color space 33 shows according to the display content according to 6 The operator thus in the form of a triangle on all possible, actually achievable by the lights mixed colors.

6 but also shows five circles 35a . 35b . 35c . 35d . 35e , in the manner of a stencil on the actually achievable color space 33 are projected. The five, discrete, ie spaced-apart circles form a sub-color space in the sum 35 , which is a true subset of the achievable color space 33 represents.

7 shows in a representation comparable 6 the actually achievable color space 33 and another sub-color space 36 that is different from the under color space 35 according to 6 different. The sub color space 36 is a substantially closed sheet of a predetermined contour K, which in turn is a true subset of the actually achievable color space 33 is. Also the sub color space 36 is projected on the actually achievable color space in the manner of a stencil.

An operator can now advantageously from several possible sub-color spaces (eg 35 and 36 ), preferably in the memory of the device 12 are stored, select a desired sub-color space.

The The operator thus has a very comfortable way to to generate predetermined, exact mixed colors.

Merely in addition, it should be noted that the luminaire according to the invention in all embodiments with an override line 37 can be provided, as this is the lamp 10b of the 1 represents. The override line 37 allows recourse to the operating device in the conventional, uncorrected manner, bypassing the electronic component 15b , Such override or direct access may be desired, for example, if a user has the maximum possible luminous flux of the associated luminaire 10b regardless of the light color generated with it, or in the event that the user does not care about the compensation and correction options.

Furthermore, it should be noted in addition that the luminaire according to the invention, insofar as it is a separate electronic component 15 with a corresponding memory, and in particular providing a correction function, can act in the manner of a converter, and in particular DALI control signals can convert into corrected DALI control signals for a downstream operating device. Alternatively, it is also possible to implement conversions that perform a protocol translation, in the manner of a gateway, eg from DMX to DALI or from DALI to DMX or from DALI to pulse-width-modulated signals or from DALI to a LON-BUS or an EIB-BUS or vice versa. This conversion function is preferably directly into the separate electronic component 15 . 15b . 15e . 15f integrated.

besitzen, wobei die einzelnen Anteile Ir, Ig und Ib jeweils die Stromanteile andeuten, die die drei Leuchtmittel 13e1, 13e2 und 13e3 aussenden sollen. So kann der Stromanteil Ir den Lichtstrom bezeichnen, den das rote Leuchtmittel 13e1 aussenden soll. Es wird deutlich, dass die Stromanteile Ir, Ig und Ib jeweils zwischen 0 und 100 % liegen können, wobei es sich anbieten könnte, und wobei dies auch von dem DALI-Protokoll vorgesehen ist, jeden der drei Werte Ir, Ig und Ib mit acht Bit zu belegen, so dass 256 unterschiedliche graduelle Unterteilungen möglich sind.In the following, it will be explained how the electronic component 15e a lamp 10e according to 3 , in particular as the correction device 24e of the component 15e the light 10e , a correction from the controller 12 obtained control signals can make:
That from the controller 12 sent out and on the device 15e For example, incoming signal may take the form of a current vector of the form

Thus, the current component Ir can denote the luminous flux that the red illuminant 13e1 to send out. It can be seen that the current proportions Ir, Ig and Ib can each be between 0 and 100%, which it could offer, and this is also provided by the DALI protocol, each of the three values Ir, Ig and Ib with eight Bit to occupy, so that 256 different graduations subdivisions are possible.

darstellen lässt, wobei die drei Variablen Or, Og und Ob jeweils den Lichtstrom bezeichnen, den die drei Leuchtmittel 13e1, 13e2 und 13e3 nach Durchführung der Korrekturen tatsächlich emittieren sollen. Die Variable Or bezeichnet den von dem roten Leuchtmittel 131 zu emittierenden Lichtstrom. Wiederum können die Werte Or, Og und Ob zwischen 0 und 100 % liegen und entsprechend einer 8-Bit-Auflösung 256 Lichtstromwerte umfassen.The current vector I with the current components Ir, Ig and Ib thus lies as an input signal or input to the component 15e at. From the component 15e an output signal (output) should be output and to the associated operating device 14e be forwarded, which equally as a vector of the form

can represent, wherein the three variables Or, Og and Ob each denote the luminous flux, the three bulbs 13e1 . 13e2 and 13e3 should actually emit after making the corrections. The variable Or denotes that of the red light source 131 to be emitted luminous flux. Again, the values Or, Og and Ob can be between 0 and 100% and include 256 luminous flux values corresponding to an 8-bit resolution.

und enthält somit neun Einträge, für die sich z.B. die folgenden typischen Werte ergeben könnten:
Die Werte für rr, gg und bb liegen ≥ 70 % und ≤ 100 % liegen, wenn es sich bei den verwendeten Leuchtmitteln um farbige LEDs handelt. Gleichermaßen liegen dann die Werte rg, rb, gr, gb, br und bg ≥ 0 und ≤ 5 %.The electronic component 15e Now automatically takes a correction of the input signal I to an output signal O, wherein for the sake of simplicity, a correction of the form O = K · I is made and K represents a matrix. The matrix or the entries of this matrix correspond to the aforementioned data record and contain the information about the properties of the lighting means. The matrix forms, for example, the form:

and thus contains nine entries for which the following typical values might result, for example:
The values for rr, gg and bb are ≥ 70% and ≤ 100% if the lamps used are colored LEDs. Likewise, the values rg, rb, gr, gb, br and bg are ≥ 0 and ≤ 5%.

Farther applies: minimum output (e.g., 70%) <(rr + rg + rb) ≤ 100%

Of the For example, minimum output is the lowest possible maximum Luminous flux of a light source.

aufweist. Dies bedeutet, dass von der Steuerung 12 das Signal ausgesandt wird, wonach lediglich das rote Leuchtmittel 13e1 angesteuert werden soll.For clarity, assume that the input signal is the form

having. This means that from the controller 12 the signal is emitted, after which only the red light source 13e1 to be controlled.

Because the red bulb 13e ₁ has an exact color value, a so-called actual color value, which may differ from a target color value, ie an ideal red by a few nanometers, the requirement arises, if necessary, low light components green or blue light through the bulbs 13e2 and 13e3 to mix in order to achieve the desired shade of red, ie the desired color light-mixed total light distribution.

so dass deutlich wird, dass für den Fall, dass die Variablen gr und br von Null verschieden sind, ein Output-Vektor

entsteht, mithin ein Steuersignal als Output an das Betriebsgerät 14e gesandt wird, welches auch Lichtanteile grünen und blauen Lichtes enthält, wenn gr und br ungleich Null sind.The output is calculated according to the formula

so that it becomes clear that in the case that the variables gr and br are different from zero, an output vector

arises, thus a control signal as output to the operating device 14e is sent, which also contains light components of green and blue light, if gr and br are not equal to zero.

It can be seen from the above that the variables gr and br indicate additional light components which are related to the light of the red light source 13e1 should be mixed to produce a specific, predefined, exact shade of red.

In other words, the electronic component takes into account 15e an exact color value of the red light source 13e1 , ie an actual value, that of a setpoint of the red light source 13e1 may differ. The correction device 24e or the component 15e can make the desired correction by applying the correction matrix K and produce an exact mixed color.

Out From the above it follows that the matrix K has nine constants contains each typically one byte, i. 8 bits in size, can be selected can.

The Correction matrix becomes more complicated when in addition to consideration production-related color differences and maximum possible Luminous flux differences also a temperature dependence considered becomes. For this, the output O results from a temperature-dependent correction matrix K (T) and the input signal I according to the formula

These Matrix shows that the individual nine contents of the matrix K (T) are temperature-dependent. The temperature-dependent Behavior of these values should therefore be known, at least approximately known be.

The Temperature Tr is, for example, the temperature of the red light source, the temperature Tg is the temperature of the green lamp and the temperature Tb is the temperature of the blue bulb.

Under circumstances enough it, a common ambient temperature, such as a board temperature, to measure, with only a single temperature reading M for disposal stands. Knowing the channel output O and the temperature reading M can on the actual Temperature of the individual bulbs (red, green, blue) are closed.

Finally, can the correction matrix K in addition also contain a correction function that the aging dependence considered the light production of the individual bulbs. This results in a correction matrix that shows the age-dependent behavior considered to

The Values Ar, Ag and Ab, i. the aging of a bulb, result itself from an integration of the associated illuminant-dependent output signal over the Time. In this respect, there is an intermediate storage of the individual outputs integrated over the time.

The consideration the production-related color and luminous flux differences and the temperature and age dependent Differences leads after all to a temperature and age-dependent correction matrix

Preferably, the correction device takes into account 24e this correction matrix, and sets that from the controller 12 obtained control signals according to the input vector I by multiplication with the matrix of K (T, A) in an output signal O to which the operating device 14e is sent.

As previously described, application of the matrix may also be instantaneous in the controller 12 take place if, for example, the matrix values of the production-related matrix K, ie a non-temperature-dependent and non-age-dependent matrix, have been transferred from the memory of the luminaire to the controller as a result of a read-out process.

alternative can also only part of the matrix correction, for example, only the correction based on the age-related behavior or only based on the temperature-related behavior, by the controller whereas a correction takes into account the maximum light streams and the exact color values are only in the luminaire.

8th shows in a schematic, broken, partially cutaway side view of an embodiment of a luminous means according to the invention 13g , for example, from an LED, according to 8th schematically sketched by an SMD (= surface mounted diode) LED is formed. The light source 13g is on a circuit board 38 attached. On the board 38 there is a memory 22g into which a data set, eg a matrix, contains the entries, the properties of this light source 13g describe, is inscribed. The light propagation of the LED shows 8th only indicated by schematic arrows.

The viewer becomes clear that the bulb 13g together with the board 38 and with the memory 22g forms a manageable unit that can be mounted in a lamp. The memory 22g can via unillustrated traces on the board 38 electrically with the bulb 13g be connected. In this case, the memory can 22g which is typically formed by an electrical component, more preferably containing a μ-processor, also a drive unit for the lighting means 13g be assigned.

In the event that the memory 22g with the bulb 13g is not electrically connected, separate connections or supply lines may be provided which the memory 22g and, separately, the bulb 13g , with elements of the lamp 10 connect.

In the store 22g is in a manner described above according to the embodiments of the 1 to 4 or in a similar manner a record is written, which equally allows a correction of control signals. The difference now is that the memory 22g the bulb 13g assigned. The memory content 22g can either be read, so that the correction function is performed by a correction device that in the lamp, but separately from the unit 39 is arranged. Alternatively, the controller can 12 , eg according to 1 to take over the correction function. Finally, there is also the option of a correction device 24g according to 8th the bulb 13g assign and this correction device 24g directly on the unit 39 that the bulbs 13g carries, arrange. corrector 24g and memory 22g can also be part of a single electronic component in the embodiment, not shown, at For example, a μ-processor and an EEPROM memory may have.

The memory 22g , the bulbs 13g is assigned, can also structurally separate from the light source 13g and of the assembly 39 be arranged and, for example, as a the bulb 13g enclosed data medium, for example in the form of a CD-ROM or in the form of an SD card, with the light source 13g or with the unit 39 be included. In this case, form the bulbs 13g and the memory 22g an allocation unit, which does not necessarily require a structural connection with each other. Are memory 22g and bulbs 13g structurally separate, is also a decentralized reading of the contents of the memory 22g possible, for example, the light source 13g with the light 10 is connectable and the memory 22g separate from this connection process with the controller 12 is connectable and can be read.

Both a structurally separate arrangement of memory 22g and bulbs 13g as well as a memory 22g and bulbs 13g comprehensive unit 39 may in one embodiment of the invention, a readout of the memory 22g allow by a component of the lamp when the bulb 13g is mounted or mounted in the luminaire.

Even though 8th An LED indicates that any other type of light source can be used with comparable memory 22g be provided. For example, a socket body carrying the luminous means, a type of lamp base or a support structure for the luminous means with the memory 22g be provided. In the event that the light bulb forms a structural unit together with an operating device for the light source, the memory is 22g can also be arranged on this unit.

The record can be stored in memory 22g be enrolled when the light source 13g or the assembly 39 that the bulbs 13g carries, is produced. The factory-inscription of the data set is therefore preferably at the lamp manufacturer.

in the The scope of the invention is any combination of all presently disclosed features with each other, even if they are different embodiments are described.
