VEHICLE LIGHT WITH A WAVELENGTH CONVERTING ELEMENT The present invention relates to a vehicle lamp according to claim 1 and to a vehicle lamp according to claim 9.

Vehicle lights for motor vehicles are known in various designs. In the prior art, there are vehicle lamps with incandescent lamps, in which different required light colors are generated by suitable color filters. The color filters can be arranged in a cover or on a glass bulb of a light bulb. By additional scattering components such as diffusers or faceted reflectors or by suitable surface structures of a cover a homogeneous luminous appearance is achieved. The use of color filters, however, is accompanied by loss of luminous intensity. Vehicle lights are also known in which colored light-emitting diodes are used instead of incandescent lamps. By using colored light-emitting diodes can be dispensed with a color filter. Furthermore, vehicle lamps with colored cold cathode discharge lamps are known.

The German priority application DE 10 2013 205 836. 5, which expressly forms part of the disclosure of the present application, also describes a vehicle lamp.

An object of the present invention is to provide a vehicle lamp. This object is achieved by a vehicle lamp with the features of claim 1 and by a vehicle lamp with the features of claim 9. In the dependent claims various developments are given.

A vehicle lamp comprises a light-emitting component which has an optical semiconductor chip, and a cover assembly which comprises a wavelength-converting element having. The light-emitting component is designed to emit light having a wavelength from a first spectral range. The wavelength converting element is formed from ^¬ to convert light having a wavelength from the first Spekt ^¬ ralbereich in light having a wavelength from a second spectral range. Advantageously, in this vehicle lamp, a wavelength conversion of light emitted by the light-emitting component takes place only in the cover arrangement of the vehicle lamp. As a result, several light functions of different colors can advantageously be realized with light-emitting components of only one color. The arrangement of the wavelength-converting element on the cover assembly of the vehicle lamp opens up advantageous freedom in the design of a luminous surface of the vehicle lamp. Advantageously, by varying the structure of the wave-converting element many different light colors can be generated.

The cover assembly has another wavelength-converting element. The further wave-converting element is designed to convert light having a wavelength from the first spectral range into light having a wavelength from a third spectral range. Here, the wavelength converting element and the further wellenlängenkon ^¬ vertierende element are adapted to produce light of different wavelengths. Advantageously, the driving ^¬ zeugleuchte thereby two illuminated areas that can shine with different colors. This can be with the vehicle lamp, for example, different signal radio ^¬ tions of a motor vehicle implement, such as a flashing light and a stop light.

In an embodiment of the vehicle lamp, the wel ^¬ lenlängenkonvertierende element embedded wavelength converting particles ^¬. Advantageously, light having a wavelength from the first spectral range can then be absorbed by the wavelength-converting particles. The wavelength-converting particles can after absorption of light having a wavelength from the first spectral range, emitting light having a wavelength from the second spectral range. The wavelength-converting particles may comprise, for example, an inorganic phosphor such as garnet, nitride, orthosilicate, quantum dots of, for example, ZnSe, CdSe or PbS, or an organic phosphor.

In an embodiment of the vehicle lamp, the wel ^¬ lenlängenkonvertierenden particles are embedded in a cover of the cover assembly. For example, the wel ^¬ lenlängenkonvertierenden particles can already be embedded during a production of the cover of the cover assembly by a molding process in the material of the cover. Advantageously, this results in a particularly simple construction of the cover assembly. In addition, the cover assembly is characterized particularly inexpensive to produce.

In one embodiment of the vehicle lamp, the wavelength-converting element is formed by a layer arranged on a cover plate of the cover arrangement. The layer can, for example, already during the preparation of From ^¬ cover disk of the cover by a multistage

Injection molding can be applied as a separate layer. The layer forming the wavelength-converting element may also be formed as a film. It is also possible to apply the layer forming the wavelength-converting element to the cover plate of the cover arrangement by electrophoretic deposition, by a printing method, by spraying or by another method. The formation of the wavelength-converting element as on the cover on ^¬ ordered layer advantageously opens up the possibility of structuring the wavelength-converting element forming layer in a lateral direction, resulting in a precise adjustability of the shape of a luminous surface of the vehicle lamp.

In one embodiment of the vehicle lamp, the layer is arranged on an inner side of the cover plate facing the light-emitting component. Advantageously, that is the Wavelength-converting element-forming layer thereby protected by the cover of the cover assembly from external influences. Thereby, damage to the wavelength converting element forming layer can be prevented.

In one embodiment of the vehicle lamp, the layer is formed as a foil. Advantageously, the layer forming the waves ^¬ length-converting element can be particularly easily arranged on the cover of the cover assembly. This allows a simple and cost-effective production of the vehicle lamp.

In an embodiment of the vehicle lamp, the element forming the wavelength converting layer on a ^¬ la teral structuring. Advantageously, thereby a lateral shape of a luminous surface of the vehicle lamp can be preset with high accuracy.

In one embodiment, the vehicle lamp, the ex ^¬ comprehensive arrangement on a light-absorbing element. In this case, the light-absorbing element is configured to absorb light having a Wel ^¬ lenlänge from the first spectral range. Advantageously, unwanted excitation of the wavelength-converting element by, for example, sunlight can be prevented by the light-absorbing element.

In one embodiment of the vehicle ^lamp , the light-absorbing element is arranged on a side of the wavelength-converting element facing away from the light-emitting component. Advantageously, the wellenlän ^¬ genkonvertierende element characterized for light emitted from the light emitting device light is accessible, while the waves ^¬ längenkonvertierende element is shielded by the lichtab ^¬ sorbing member of ambient light to the outside.

In one embodiment, the vehicle lamp has the Ab ^¬ deck assembly light-scattering particles. The light-scattering particles may, for example, have T1O ₂ . Advantageous- As a result, the light-scattering particles cause scattering and thus a more uniform distribution of light. As a result, the vehicle lamp can advantageously have a particularly homogeneous illuminated luminous surface. In one embodiment of the vehicle lamp, the wel ^¬ lenlängenkonvertierende element embedded light-scattering particles. Advantageously, the embedded into the waves ^¬ längenkonvertierende element light scattering particles then cause a scattering of the light generated in the wavelength converting element having a wavelength from the second spectral range and in a particularly uniform Ver ^¬ distribution of the light having the wavelength from the second

Spectral range over the entire range of the wavelength-converting element. This can advantageously result in a particularly homogeneous illuminated luminous surface.

In an embodiment of the vehicle lamp, the Ab ^¬ deck assembly to an image-forming optical element. ^¬ advantageous way legally, the optical imaging element of the cover assembly of the vehicular lamp ^¬ cause a beam shaping of a signal emitted by the vehicle lamp light. As a result, light from the vehicle lamp is radiated mainly in a preferential ^¬ direction.

In one embodiment of the vehicle lamp, the optically imaging element is formed on an outer side of the cover arrangement facing away from the light-emitting component. For example, the optically imaging element may be formed by an outer side of a cover of the cover assembly. Advantageously, this results in a particularly compact and inexpensive design of the cover assembly of the vehicle lamp.

In one embodiment of the vehicle lamp, this has a further light-emitting component. In this case, the light-emitting component and the further light-emitting component can be controlled separately from one another. Advantageously, the two light-emitting components of the driving then serve for different signal functions of the vehicle lamp. For example, the lichtemit ^¬ animal end device can be used to implement a brake light function and serve the further light emitting device for Rea ^¬ Capitalization a flashing light function. Advantageously, the light emitting device and the further light emitting device may be part of an identical design and in particular emit light of wavelengths from the same Spekt ^¬ ralbereich. The light-emitting component and the further light-emitting component can also jointly serve to implement only one signal function of the vehicle lamp. In this case, for example, the light-emitting component and the further light-emitting component can be operated simultaneously to increase the luminous intensity. However, it is also possible for the light-emitting component and the further light-emitting component to be switched on and off in chronological succession in order, for example, to achieve a spatial movement of a light spot visible on the vehicle light.

Another vehicle lamp comprises a light emitting device having a first optoelectronic semiconductor chip, and a cover assembly comprising a wavelength converting element and a light absorbing element. In this case, the first optoelectronic semiconductor chip is designed to emit light having a wavelength from a first spectral range. The light absorbing element is disposed between the light emitting device and the wavelength converting element. The light-absorbing element is designed to absorb light having a wavelength from the first spectral range. The light-absorbing element has a recess that is transparent to light having a wavelength from the first spectral range. The wavelength converting element is configured to convert light having a wavelength from the first spectral range into light having a wavelength from a third spectral range. In this vehicle lamp, light emitted from the first optoelectronic semiconductor chip of the light emitting device with a wavelength from the first spectral region only in the region of the recess of the light-absorbing element to the wavelength-converting element and are converted there into light having a wavelength from the third spectral range. In the remaining surface portions of the light-absorbing member, light emitted from the first optoelectronic semiconductor chip of the light-emitting device of the vehicle lamp is absorbed by the light-absorbing member at a wavelength from the first spectral range. Thus, a form of an externally visible to the vehicle ^¬ light spot can be set at this vehicle lamp, the shape of the recess of the lichtab ^¬ sorbing member.

In one embodiment of the vehicle lamp, the light-emitting component has a second optoelectronic semiconductor chip which is designed to emit light having a wavelength from a second spectral range. In this case, the light-absorbing element is transparent to light having a wavelength from the second spectral range. In this vehicle lamp, light emitted by the second optoelectronic semiconductor chip of the light-emitting component with a wavelength from the second spectral range can be brought out without absorption by the light-absorbing element. As a result, the vehicle lamp can have a luminous area that can emit light having a wavelength from the second spectral range. In addition, part of this luminous area can simultaneously or alternatively emit light with a wavelength from the third spectral range. A particular advantage is that without emission of light having a wavelength from the first spectral range by the first optoelectronic semiconductor chip of the light-emitting component of the vehicle lamp, the portion of the recess of the light-absorbing element is not distinguishable from the remaining surface portions. Thus, the luminous area of the vehicle lamp can be used for different Sig ^¬ nalfunktionen a motor vehicle at the same time, in ^¬ example as brake light or tail light and a flashing light. This advantageously makes it possible to design the vehicle lamp with compact dimensions and pleasing appearance.

In one embodiment of the vehicle lamp, the second spectral range is a longer wavelength spectral range than the first spectral range. The first spectral range may include, for example, the blue spectral range of visible light. The second spectral range may include, for example, the red spectral range of the visible light. The third spectral range may include, for example, the yellow spectral range of visible light.

In an embodiment of the vehicle lamp, the Ab ^¬ deck assembly on a diffuser plate which is disposed between the light emitting component and the light-absorbing element. The diffuser plate can, for example, have embedded scattering particles and serve to homogenize a light emitted by the light-emitting component of the vehicle light. In addition, the diffuser plate may cause mechanical stabilization of the cover assembly.

In an embodiment of the vehicle lamp, the light-emitting device ^¬ is formed as a light box. Before ^¬ geous enough, this allows a particularly simple construction of the light-emitting component of the vehicle lamp.

In one embodiment, the vehicle lamp includes the light emitting device a light guide and a plurality arranged on side faces of the light guide optoelectrochemical ^¬ tronic semiconductor chips. Advantageously, this allows a design of the light-emitting component of the vehicle lamp with a particularly low overall depth. The light guide of the light emitting device may also cause homogenization of the light emitted by the optoelectronic semiconductor chip of the light emitting device.

In one embodiment, the vehicle lamp includes the light emitting device on a plurality of optoelectronic half ^¬ semiconductor chip, which can be controlled separately. This can enable a simple brightness control. The first optoelectronic semiconductor chips of the light-emitting component can also be arranged next to one another in such a way that a light spot visible on an outside of the vehicle lamp can be displaced along a longitudinal direction by driving different individual first optoelectronic semiconductor chips of the light-emitting component. This can be achieved with the vehicle lamp dynamic lighting effects. The above-described characteristics, features, and advantages of this invention, as well as the manner in which they will be achieved, will become clearer and more clearly understood in connection with the following description of the embodiments, which will be described in connection with the drawings. In each case show in highly schematic representation:

Figure 10 is a perspective view of a fourth driving ^¬ zeugleuchte. 1 shows a highly schematic perspective Dar ^¬ position of a first vehicle lamp 100. The first driving ^¬ imaging light 100 may for example serve as a signal lamp in a motor vehicle. The first vehicle light 100 can serve, for example, as a backlight, as a brake light, as a fog-lamp or ^¬ as turn signals. The first vehicle ^¬ light 100 can combine several of these functions.

The first vehicle lamp 100 has a light-emitting component 200. The light-emitting component 200 has an optoelectronic semiconductor chip 201. The optoelectronic semiconductor chip 201 may, for example, a

Be a light-emitting diode chip (LED chip) or a laser chip. The optoelectronic semiconductor chip 201 may, for example, also be an OLED chip designed as a point-shaped or planar light source. The light emitting device 200 may include a housing in which the optoelectronic semiconductor chip 201 is disposed. The housing of the light-emitting ^{component ¬} 200, for example, electrical contacts for electrical contacting of the optoelectronic semiconductor terchips 201 have.

The optoelectronic semiconductor chip 201 of the light emitting device 200 is designed to emit light 101 having a wavelength from a first spectral range. For example, the optoelectronic semiconductor chip 201 of the light emitting device 200 may be configured to emit light 101 having a wavelength from the blue spectral range. The light 101 may, for example, have a wavelength in the range between 440 nm and 455 nm. However, light 101 emitted by the light-emitting component 200 may also have a wavelength from another spectral range, for example from the ultraviolet spectral range.

The first vehicle lamp 100 has a cover assembly 300. The cover assembly 300 is spatially spaced from the light emitting device 200 of the first vehicle lamp 100 and serves to cover and mechanically protect the light emitting device 200. The cover assembly 300 also forms a visible from the outside of the luminous surface of the first vehicle lamp 100. For this purpose, the cover assembly 300 generally has a much larger surface than the light emitting device 200 on.

The cover assembly 300 of the first vehicle lamp 100 further serves to convert a wavelength of the light 101 emitted from the optoelectronic semiconductor chip 201 of the light emitting device 200 of the first vehicle lamp 100 to a wavelength of the first spectral range. The cover assembly 300 at least partially converts the light 101 having a wavelength from the first spectral range into light 102 having a wavelength from a second spectral range. The second spectral range may differ from the first spectral range. The light 102 having a wavelength from the second spectral range may be, for example, white light or yellow light having a wavelength in the range between 550 nm and 650 nm. The light 102 having a wavelength from the second spectral range generated by the cover assembly 300 is output from the first vehicle lamp 100 to the outside.

Various variants of the cover assembly 300 of the first vehicle lamp 100 will be explained below. Each of the variants described by ^¬ following may be used as cover assembly 300 in the first vehicle light 100 of FIG. 1 FIG. 2 shows a schematic sectional illustration of a first cover arrangement 310. The first cover arrangement 310 can be used as cover arrangement 300 in the first vehicle lamp 100 of FIG. The first cover assembly 310 has an inner side 301, which faces the light-emitting component 200 of the first vehicle lamp 100. Opposite the inner side 301, the first cover arrangement 310 has an outer side 302, which forms an externally visible outer surface of the first vehicle lamp 100.

The first cover assembly 300 has a first cover plate 410. The first cover plate 410 has an inner side 401, which forms the inside 301 of the first cover assembly 310. In addition, the first cover plate 410 has an outer side 402, which forms the outer side 302 of the first cover assembly 310. In the example shown in Figure 1, the first cover 410 is shown as a flat plate. The first

Cover 410 may, however, also have a curvature. The inner surface 401 and / or the outer side 402 of the first Ab ^¬ cover plate 410 may have a structure, for example fluting. The first cover plate 410 may comprise a plastic material ^¬. For example, the first cover plate may comprise polycarbonate or PMMA. The material of the first cover panel 410 is preferably substantially optically transparent. The material of the first cover plate 410 may also be colored red, for example. In this case, the cover assembly 300, 310 of the first vehicle lamp 100 appears red when the light-emitting device 200 of the first ^¬ vehicle lamp 100 is turned off and does not emit light.

The first cover plate 410 of the first cover assembly 310 forms a first wavelength converting element 510. Light 101 having a wavelength from the first spectral range irradiated in the first cover plate 410 at least partially turns into the light source 102 having a wavelength in the first cover plate 410 forming the first wavelength converting element 510 converted from the second spectral range.

For this purpose, the first cover plate 410 forming the first wavelength-converting element 510 has an embedded phosphor. The embedded phosphor can already have been introduced into the material of the first cover plate 410 during the production of the first cover plate 410 by, for example, a molding process. The embedded phosphor may be, for example, an inorganic phosphor such as garnet, nitride, orthosilicate or an organic phosphor

Be fluorescent. The phosphor may also have quantum dots of, for example, ZnSe, CdSe or PbS. The phosphor can be used, for example, in the form of wavelength-converting particles. be embedded in the first wavelength converting element 510 forming the first cover 410.

The first wavelength-converting element 510 may be formed by a surface portion of the first cover plate 410 or by the entire first cover plate 410. For this purpose, a phosphor is embedded either only in a partial area of the first cover panel 410 or in all areas of the first cover panel 410.

In addition, light-diffusing particles may be embedded in the first cover panel 410 of the first cover assembly 310. The light scattering particles may have, for example ^¬ T1O _second The light-diffusing particles may serve to spread light within the first cover plate 410 by scattering. In particular, in the region of the first cover plate 410 forming the first wavelength-converting element 510, light 102 having a wavelength from the second spectral range can be distributed uniformly over the surface of the first cover plate 410 by the light-scattering particles. This results in a homogeneous light impression on the outside 302 of the first cover arrangement 310.

FIG. 3 shows a schematic sectional illustration of a second cover arrangement 320. The second cover arrangement 320 can be used as cover arrangement 300 in the first vehicle lamp 100 of FIG. The second cover arrangement 320 comprises a second cover plate 420, a second wavelength-converting element 520 and a first protective layer 620. The second cover plate 420, the second wavelength-converting element 520 and the first protective layer 620 are each formed in a planar manner and arranged in a layered relationship. An outer side 402 of the second cover plate 420 forms an outer side 302 of the second cover assembly 320. The second wavelength-converting element 520 is adjacent to an inner side 401 of the second cover plate from ^¬ 420th The first protective layer 620 is adjacent to a side of the second side facing away from the second cover 420 wavelength converting element 520. A side of the first protective layer 620 facing away from the second wavelength-converting element 520 forms an inner side 301 of the second covering arrangement 320. The inner side 301 of the second covering arrangement 320 faces the light-emitting component 200.

The second cover 420 of the second cover assembly 320 may be formed like the first cover 410 of the first cover assembly 310. However, the second cover 420 has no embedded phosphor. Instead, the second wavelength-converting element 520 is formed in the second cover assembly 320 as a separate layer. The layer of the second cover arrangement 320 forming the second wavelength-converting element 520 may, for example, have been formed on the inner side 401 of the second cover plate 420 in a multi-stage injection molding process. In this case, the second wavelength-converting element 520 may have the same material as the second cover 420. However, the second wavelength-converting element 520 may also be formed by, for example, a printing process, such as a screen printing or stencil printing process, by electrophoretic deposition, by spraying or by another method may have been applied to the inside 401 of the second cover 420. The second wavelength-converting element 520 can also be formed as a film. The film may, for example, be laminated to the inside 401 of the second cover 420.

In any case, the second wavelength-converting element 520 comprises a phosphor. The phosphor of the second wavelength-converting element 520 may be formed like the phosphor of the first wavelength-converting element 510 of the first cover arrangement 310.

The first protection layer 620 comprises a material that is substantially optically transparent to light 101 having a wavelength from the first spectral range. The first

Protective layer 620 serves for the mechanical protection of the second Wavelength-converting element 520. The first protective layer 620 may also be omitted.

Light 101 having a wavelength from the first spectral range emitted by the light-emitting component 200 and falling on the inner cover 301 on the inner side 301 is at least partially converted into light 102 having a wavelength from the second spectral range in the second wavelength-converting element 520. The light 102 having a wavelength from the second spectral range can exit from the second wavelength-converting element 520 through the second cover 420 and can be emitted on the outside 302 from the second cover 320.

In the second cover 420 and / or the second wave ^¬ length-converting element 520 of the second cover 320 may additionally be embedded light-scattering particles. These may be formed as described with reference to the first cover assembly 310.

FIG. 4 shows a schematic sectional view of a third cover arrangement 330. The third cover arrangement 330 can be used as cover arrangement 300 in the first vehicle lamp 100 of FIG.

The third cover assembly 330 includes a third cover 430, a light absorbing element 730, a third wel ^¬ lenlängenkonvertierendes element 530 and a second protective layer 630. The third cover 430, the lichtabsor ^¬ bierende element 730, the third wavelength-converting element 530 and the second Protective layer 630 are each formed flat and layered adjacent to each other. An outer side 402 of the third cover plate 430 forms an outer side 302 of the third cover arrangement 330. The light-absorbing element 730 adjoins an inner side 401 of the third cover plate 430. On a side of the light-absorbing element 730 facing away from the third cover disk 430, the third wavelength-converting element 530 adjoins. On a side of the light-absorbing element 730 facing away from the third wavelength-converting element 530 adjoins the second protective layer 630. A direction away from the third wellenlän ^¬ genkonvertierenden element 530 side of the second protective layer 630 forms an inner surface 301 of the third cover assembly 330. The inner surface 301 of the third cover assembly 330 faces the light emitting device 200th

The third cover plate 430, the third wellenlängenkonver ^¬ animal element 530 and the second protective layer 630 of the third cover assembly 330 can be designed and prepared as the second cover plate 420, the second wellenlängenkonver ^¬ animal element 520 and the first protective layer 620 of the second cover assembly 320 of the Figure third

In addition, in the third cover assembly 330 between the third cover plate 430 and the third wavelength-converting element 530, the light-absorbing element 730 is still inserted. The light-absorbing element 730 is formed from ^¬ light to absorb 101 with a wavelength from the first spectral range. The light absorbing element 730 may also be referred to as a filter. Light 101 emitted by the light-emitting component 200 has a

Wavelength from the first spectral range is converted in the third wavelength-converting element 530 of the third cover arrangement 330 into light 102 having a wavelength from the second spectral range. The light 102 having a wavelength from the second spectral range may pass through the light absorbing member 730 and the third cover plate 430 unhindered and emitted on the outside 302 of the third cover assembly 330. However, light 101 having a wavelength from the first spectral range, for example, sunlight or other ambient light, falling from the outside 302 of the third cover assembly 330 to the third cover assembly 330 is absorbed in the light absorbing member 730 and can not penetrate to the third wavelength converting member 530. As a result, ambient light incident on the third cover arrangement 330 from the outside is prevented from the phosphor contained in the third wavelength-converting element 530 is activated and converted into light 102 having a wavelength from the second spectral range.

It is also possible to combine the light absorbing element 730 and the third wavelength converting element 530. In this case, a light-absorbing material which is adapted to absorb light having a wavelength 101 ^¬ ralbereich from the first Spekt embedded in the third wavelength-converting element 530th

FIG. 5 shows a schematic sectional representation of a fourth cover arrangement 340. The fourth cover arrangement 340 can be used as cover arrangement 300 in the first vehicle lamp 100 of FIG.

The fourth Abdeckordnung 340 comprises a fourth cover plate 440, a fourth wavelength-element 540, and a third protective layer 640. The fourth cover plate 440, the fourth wavelength-converting element 540 and the third protective layer 640 are stacked adjacent to each other arranged at ^¬. An outer side 402 of the fourth cover plate 440 forms an outer side 302 of the fourth cover arrangement 340. The fourth wavelength-converting element 540 adjoins an inner side 401 of the fourth cover plate 440. The third protective layer 640 adjoins a side of the fourth wavelength-converting element 540 facing away from the fourth cover disk 440. A side of the third protective layer 640 facing away from the fourth wavelength-converted element 540 forms an inner side 301 of the fourth covering arrangement 340. The inner side 301 of the fourth covering arrangement 340 faces the light-emitting component 200.

The fourth cover plate 440, the fourth wavelength-converting element 540 and the third protective layer 640 of the fourth cover assembly 340 are substantially formed and manufactured like the second cover plate 420, the second wavelength converting element 520 and the first protective layer ^¬ 620 of the second cover assembly 320 of the FIG. 3. In addition, the fourth cover 440 of the fourth cover assembly 340 forms an optically imaging element 840. For this purpose, the outer side 302 of the fourth cover assembly 340 forming outside 402 of the fourth cover 440 is suitably structured. For example, the outer side 402 of the fourth cover 440 may have a lens structure. The optical imaging element 840 is configured such that light 102 extending from the fourth wavelength-converting element 540 through the fourth cover disk 440 to the outside 302 of the fourth cover arrangement 340 with a wavelength from the second spectral range, which can have a broad angular distribution, passes through the optical imaging element Element 840 is deflected such that it is emitted on the outer side 302 of the fourth cover assembly 340 as a directed light substantially perpendicular to the fourth cover assembly 340. The optically imaging element 840 of the fourth cover arrangement 340 thus effects a bundling of the light 102, which is emitted on the outside 302 of the fourth cover arrangement 340, with a wavelength from the second spectral range. Figure 6 shows a schematic plan view of a fifth From ^¬ deck assembly 350. The fifth cover assembly 350 includes a fifth cover panel 450 and a fifth wellenlängenkonver ^¬ animal element 550. Figure 6 shows a plan view of an outer side 402, the fifth cover plate 450, an outer side 302 the fifth cover assembly 350 forms. The fifth cover 450 and the fifth wavelength converting element 550 of the fifth cover assembly 350 may be formed as in the first cover assembly 310 of FIG. 2, the second cover assembly 320 of FIG. 3, the third cover assembly 330 of FIG. 4, or the fourth cover assembly 340 of FIG ,

In the lateral direction of the outer side 302 of the fifth cover arrangement 350, the fifth cover arrangement 350 has a first surface section 351 and a second surface section 352. The outside 402 of the fifth cover 450 includes the first surface portion 351 and the second surface portion 352 and forming in two surface portions 351, 352, the outer side 302 of the fifth cover assembly 350. The fifth wavelength-converting element 550 is formed in the lateral direction ^¬ le diglich in the second surface portion 352nd In the illustrated example, the first surface section 351 surrounds the second surface section 352 in an annular manner. However, the first surface portion 351 and the second surface portion 352 may be disposed on the outside 302 of the fifth cover assembly 350 in other ways, for example, side by side. The second face portion 352 may comprise and at ^¬ play, form a stripe pattern, a dot pattern, engravings or other shapes in the lateral direction also a more complex geometry. The lateral shape of the second surface portion 352 can be determined, for example, by photostructuring, printing or stenciling.

Preferably uniformly monochrome if the light emitting device 200 which is adapted to emit light 101 having a wavelength from the first Spekt ^¬ ralbereich, is not turned on, that is does not emit light, the outer side 302 of the fifth cover assembly 350 appears. The Au ^¬ ßenseite 302 of the fifth cover assembly 350, for example, appear uniformly light gray or white. The outside 302 of the fifth cover assembly 350 may also appear uniformly dark gray or black. In this case, the fifth cover 450 of the fifth cover assembly 350 may be formed, for example, as a smoked glass. If the fifth From ^¬ cover plate 450, the fifth cover assembly is colored red 350, the outer side 302 of the fifth cover assembly 350 can appear uniform red when the light emitting device 200 emits no light 101 having a wavelength from the first spectral range.

The cover assembly 350 equipped with the fifth first vehicle lamp 100 may include in addition to the light emitting device 200 to emit light 101 having a wavelength in the first spectral region, other light emitting construction ^¬ elements that are intended to light having a Emitting wavelength from the red spectral range. Red light emitted by these light-emitting components can freely penetrate the fifth cover arrangement 350 in both the first surface section 351 and in the second surface section 352, thus causing the outer cover 302 of the fifth cover arrangement 350 to glow red. A wavelength conversion of the red light in the fifth wavelength-converting element 550 of the fifth cover assembly 350 does not occur. When the light-emitting device 200 is turned on and emits light 101 having a wavelength from the first spectral range, this light 101 having a wavelength from the first spectral range in the fifth wavelength-converting element 550 in the second surface portion 352 of the fifth cover assembly 350 is emitted into light 102 having a wavelength converted to the second spectral range. Thus, the outer side 302 of the fifth cover assembly 350 appears in the second surface portion 352, the fifth cover assembly 350 when the light emitting device 200 in the color of the light 102 having a wavelength from the second Spekt ^¬ ralbereich, for example, yellow.

Figure 7 shows a schematic plan view of a sixth cover assembly 360. The cover assembly 360, a sixth sixth cover plate 460 includes a sixth wavelength-converting member 560 and a seventh wellenlängenkon ^¬ vertierendes element 565. A visible in Figure 7 outer side 302 of the cover assembly 360 has sixth a first surface portion 361, a second surface portion 362, and a third surface portion 363. The arrangement and shape of the surface portions 361, 362, 363 can be chosen at will. The sixth wavelength-converting element 560 is arranged in the second surface section 362 in or behind the sixth cover disk 460. The seventh wellenlängenkonver ^¬ animal element 565 is disposed in the third surface section 363 in or behind the sixth cover plate 460th In the first Surface portion 361, the sixth cover assembly 360 has no wavelength converting element.

The sixth wavelength-converting element 560 may be configured to convert light 101 having a wavelength from the first spectral range into light 102 having a wavelength from the second spectral range, for example the yellow spectral range. The seventh wavelength-converting element 565 can be provided, for example, to convert light 101 having a wavelength from the first spectral range into white light.

If the first vehicle lamp 100 is provided with the sixth covering ^¬ assembly 360, so, the first vehicle lamp 100 includes at least two light emitting devices 200 which are adapted to emit light 101 having a wavelength from the first spectral range. The two light-emitting components 200 can be controlled separately from each other. Furthermore, in this case, the first vehicle lamp 100 has optical fibers and / or diaphragms, which ensure that light 101 emitted by the first light-emitting component 200 with a wavelength from the first spectral range only to the sixth wavelength-converting element 560, but not to the seventh wavelength-converting Element 565 can pass, and emitted by the second light-emitting device 200 light 101 having a wavelength from the first spectral range only to the seventh wavelength-converting element 565, but not to the sixth wavelength-converting element 560 can pass.

If the at least two light-emitting components 200 provided for emitting light 101 having a wavelength from the first spectral range are switched off and do not emit light 101, the outside 302 of the sixth cover assembly 360, like the outside 302 of the fifth cover assembly 350, may be monochrome, appear dark or colored. If the first of the light-emitting devices 200 is turned on, light 101 comes out with one wavelength the first spectral range to the sixth wavelength-converting element 560 and is there converted into light 102 having a wavelength from the second spectral range, for example, yellow light. The second surface section 362 of the outer side 302 of the sixth cover arrangement 360 then appears in the color of the light 102 with a wavelength from the second spectral range, that is, for example, yellow. If the second of the light-emitting components 200 is switched on, then light 101 with one wavelength passes from the first spectral range to the seventh wavelength-converting element 565 and is converted there into, for example, white light. In this case, the third surface portion 363 of the outside 302 of the sixth cover assembly 360, for example, appears white.

It is also possible to form a cover assembly 300 with further surface portions, on which in or behind a cover plate of the cover assembly 300 further wavelength-converting elements are arranged, which are provided for generating further light colors. For example, surface portions for red, yellow and white light may be provided.

8 shows a highly schematic perspective Dar ^¬ position of a second vehicle lamp 110. The second driving ^¬ imaging light 110 has similarities with the first vehicle lamp 100 on. Matching components are identified in Figure 8 with the same reference numerals as in Figure 1 and will not be described again in detail below. In particular, the second vehicle lamp 110 has a cover assembly 300. The cover assembly 300 may be formed like the first cover assembly 310, the second cover assembly 320, the third cover assembly 330, the fourth cover assembly 340, the fifth cover assembly 350, or the sixth cover assembly 360.

The cover assembly 300 of the second vehicle lamp 110 has an elongated shape which extends along a longitudinal direction 111 ^¬ . The second vehicle lamp 110 includes a first lichtemit ^¬ animal splitting component 210, a second light emitting device 220, a third light emitting device 230 and a fourth light emitting device 240th Each of the light emitting devices 210, 220, 230, 240 is configured to emit light 101 having a wavelength from the first spectral range. Of course, the second vehicle lamp 110 may also have fewer or more than four light-emitting components 210, 220, 230, 240. The cover assembly 300 is configured to convert light 101 having a wavelength from the first spectral range to light 102 having a wavelength from the second spectral range.

The light-emitting components 210, 220, 230, 240 are arranged next to one another in the longitudinal direction 111. The light 101 emitted by the first light-emitting device 210 partially overlaps on the cover assembly 300 with the light emitted by the second light-emitting device 220. This, in turn, partially overlaps with the light emitted by the third light ^¬ emitting device 230 light 101. The light emitted from the third light emitting device 230 light 101 overlaps at the location of the cover assembly 300 partially with the light emitted by the fourth light emitting device 240 light 101. The light emitting by the Components 210, 220, 230, 240 on the cover assembly 300 can be generated light spots of the light 102 having a wavelength from the second spectral range are thus arranged along the longitudinal direction 111 of the cover assembly 300 partially overlapping side by side.

The light emitting devices 210, 220, 230, 240 can be switched on and off separately. If the light-emitting components 210, 220, 230, 240 are switched on and off sequentially one after the other, a light spot migrating in the longitudinal direction 111 of light 102 having a wavelength from the second spectral range results at the cover arrangement 300. This can be used for example for a dynamic turn signal function in which a

Light spot migrates towards a vehicle side to the outside. It is also possible to use the light-emitting components 210, 220, 230, 240 according to a pulse width modulation method

(PWM method) to control a brightness of the light 101 emitted by the light emitting devices 210, 220, 230, 240 with a wavelength of the first spectral range. By increasing and decreasing variation of the brightness of the individual light-emitting components 210, 220, 230, 240, a particularly continuous movement of the light spot on the cover arrangement 300 can be achieved. Also provided by in the cover assembly 300 light-scattering

Particle, a uniformity of the movement of the light spot on the cover assembly 300 in the longitudinal direction 111 can be increased.

It is also possible to choose the distances between the individual light-emitting components 210, 220, 230, 240 of the second vehicle lamp 110 to be smaller than the spacings of the light spots that can be generated by the individual light-emitting components 210, 220, 230, 240 at the location of the cover arrangement 300. The light 101 emitted by the individual light-emitting components 210, 220, 230, 240 with a wavelength from the first spectral range can be produced by means of a layered laser

Light guide spatially distributed and transported to the longitudinally 111 further spaced and overlapping areas of the light spots on the cover assembly 300.

FIG. 9 shows a schematic perspective exploded view of a third vehicle lamp 1000. The third vehicle lamp 1000 has correspondences with the first vehicle lamp 100 and the second vehicle lamp 110. The above descriptions of the first vehicle lamp 100 and the second vehicle lamp 110 also apply to the third vehicle lamp 1000, unless deviations are explicitly shown below.

The third vehicle lamp in 1000, for example, serve as Sig ^¬ nalleuchte in a motor vehicle. The third driving ^¬ zeugleuchte 1000, for example, as a tail light, as

Brake light, serve as a fog tail light or as a turn signal. The Third vehicle lamp 1000 can in particular combine several of these functions.

The third vehicle lamp 1000 has a light-emitting device 1100. The light-emitting device 1100 is configured to emit visible light. For this purpose, the light-emitting component 1100 has a plurality of first optoelectronic semiconductor chips 1110 and a plurality of second optoelectronic semiconductor chips 1120. The first optoelectronic semiconductor chips 1110 are designed to emit light having a wavelength from a first spectral range, for example light having a wavelength from the blue spectral range. The second optoelectronic semiconductor chips 1120 are configured to emit light having a Wel ^¬ lenlänge from a second spectral region, for example light with a wavelength in the red spectral region.

The light-emitting device 1100 of the third vehicle ^¬ light 1000 is formed in the illustrated example, as in a jet from ^¬ page 1101 open light box. On the emission side 1101 opposite side and the bright side ^¬ From 1101 vertical sides, designed as a light box emitting device is closed in 1100 by side walls ^¬ 1130th It is thereby achieved that the light-emitting component 1100 emits light essentially only on its emission side 1101.

The first optoelectronic semiconductor chip 1110 and the second optoelectronic semiconductor chip 1120 of the light-emitting device ^¬ 1100 are arranged at the third vehicle lamp 1000 in a direction parallel to a longitudinal direction 1001 series. The first optoelectronic semiconductor chips 1110 of the light emitting device 1100 of the third vehicle lamp 1000 can be controlled independently of one another, in particular switched on and off individually. This he ^¬ enables, for example, the individual first optoelectronic see semiconductor chips in 1110 along the longitudinal direction 1001 sequentially switched on and off again. The third vehicle lamp 1000 has a cover assembly 1200, which is shown in Figure 9 in an exploded view. In fact, the individual elements of the cover assembly 1200 of the third vehicle lamp 1000, as in the cover assemblies 300, 310, 320, 330, 340, 350, 360 of Figures 1 to 7, are connected flat to each other. The cover assembly 1200 covers the opened emission side 1101 of the light emitting device 1100 of the third vehicle lamp 1000.

The cover assembly 1200 of the third vehicle lamp 1000 includes a diffuser plate 1210, a light-absorbing

Element 1220, a wavelength-converting element 1230 and a protective layer 1240. The diffuser plate 1210 is disposed on the side facing the light-emitting device 1100 side of the cover assembly 1200. The protective layer 1240 is arranged on the side of the cover arrangement 1200 facing away from the light-emitting component 1100. The light absorbing member 1220 is disposed between the wavelength converting element 1230 and the diffuser plate 1210. The wellenlängenkon ^¬ vertierende element 1230 is disposed between the protective layer 1240 and the light-absorbing element 1220th The light-absorbing member ^¬ 1220 thus disposed closer in the animal lichtemit ^¬ forming device 1100 as the wavelength converting element ^¬ 1230th

The diffuser plate 1210 may serve to scatter from the animal lichtemit- forming device 1100 on the emission side 1101 abge ^¬ incident light diffusely to increase homogeneity and / or an isotropy of light. The diffuser plate 1210 may also serve to mechanically stabilize the cover assembly 1200. However, the diffuser plate 1210 may also be omitted. The protective layer 1240 may serve to protect the cover assembly 1200 from damage by external agents. The protective layer 1240 may also be omitted.

The light-absorbing member 1220 may also be used as filters be ^¬ records. The light absorbing element 1220 is configured to emit light having a wavelength from the first To filter out spectral range. The light-absorbing element

1220 thus filters out light emitted by the first optoelectronic semiconductor chips 1110 of the light-emitting component 1100 of the third vehicle lamp 1000 from the light emitted by the light-emitting component 1100. On the other hand, the light of the light emitting device 1100 emitted from the second optoelectronic semiconductor chips 1120 passes through the light absorbing element 1220.

The light-absorbing element 1220 has at least one recess 1221. In the example shown in FIG. 9, the light absorbing member 1220 has a plurality of recesses

1221, which are formed as breakthroughs and along the longitudinal direction 1001 of the third vehicle lamp 1000 are arranged side by side. In the areas of the recesses 1221, light emitted from the light-emitting device 1100 can pass through the light-absorbing element 1220 unhindered regardless of the wavelength of the light. Thus, also emitted by the first opto-electronic semiconductor chip 1110 of the light emitting device 1100 light having a wavelength from the first spectral range 1200 to pass the FLAE ^¬ chenbereichen of the recesses 1221, the light-absorbing member 1220, the cover assembly.

Otherwise, the light absorbing member 1220 may be formed like the light absorbing member 730 of the third cover assembly 330 shown in FIG.

The wavelength-converting element 1230 of the cover arrangement 1200 of the third vehicle lamp 1000 is configured to convert light having a wavelength from the first spectral range into light having a wavelength from a third spectral range. The third spectral range can be, for example, the yellow spectral range. Light having a wavelength from the second spectral range may pass through the wavelength converting element 1230 substantially unhindered and unaffected. The wavelength-converting element 1230 may be formed like the wavelength-converting elements 510, 520, 530, 540, 550, 560, 565 of FIGS. 2 to 7. Of the second optoelectronic semiconductor chip 1120 of the light emitting device 1100 of the third vehicle light 1000 emitted light, the light-absorbing member 1220 and the wavelength converting element 1230 covering arrangement 1200, the third vehicle lamp 1000 mainly through unhindered and is radiated to the outside of the Ab ^¬ deck assembly 1200 , If the second opto ^¬ lektronischen semiconductor chips 1120 are formed to emit red light, and if only the second optoelectronic semiconductor chips 1120 and not the first optoelectronic semiconductor chips 1110 of the light emitting device 1100 of the third vehicle lamp 1000 are in operation, the third vehicle lamp 1000 may, for example emit red light in one color.

Light emitted by the first optoelectronic semiconductor chips 1110 of the light emitting device 1100 of the third vehicle lamp 1000 is transmitted only in the area of the recesses 1221 of the light absorbing element 1220 of the cover arrangement 1200 and is thereby modulated laterally. The water passing through the recesses 1221 of the light-absorbing member 1220 with light of a wavelength from the first Spekt ^¬ ralbereich is converted by the following wavelength-converting element 1230 of the cover 1200 in light having a wavelength from the third spectral range. This light having a wavelength from the third spectral range is the third vehicle lamp 1000 1221 of lichtab ^¬ sorbing element radiated to the outside of the cover assembly 1200 via the cutouts 1220 disposed surface areas, wherein the lateral modulation caused by the recesses 1221 is maintained.

If, at the same time, the second optoelectronic semiconductor chips 1120 of the light emitting device 1100 of the third vehicle lamp 1000 are also in operation, then the light having the wavelength from the third spectral range is emitted by the second optoelectronic semiconductor chips 1120 Superimposed light with a wavelength from the second spectral range.

If only part of the first optoelectronic semiconductor chips 1110 of the light emitting device 1100 of the third vehicle lamp 1000 is switched on, then light having a wavelength from the first spectral range only passes through some of the recesses 1221 of the light absorbing element 1220 of the cover arrangement 1200 and accordingly only in these areas is converted by the wavelength-converting element 1230 of the cover assembly 1200 into light having a wavelength from the third spectral range and emitted only in the region of these recesses 1221 on the outside of the cover assembly 1200 of the third vehicle lamp 1000. If successively different first optoelectronic semiconductor chips 1110 are switched on and off, then in this way a movable light spot can be generated on the outside of the cover arrangement 1200 of the third vehicle lamp 1000. In ^¬ play, the first optoelectronic semiconductor chip 1110 of the light emitting device 1100 along the longitudinal direction 1001 can be switched on successively and switched off to one of the third in this manner in the longitudinal direction 1001

Vehicle lamp 1000 to generate wandering light spot of light with a wavelength from the third spectral range.

FIG. 8 shows a schematic illustration of a fourth vehicle lamp 2000. The fourth vehicle lamp 2000 has clear correspondences with the third vehicle lamp 1000. In the following, therefore, substantially the aspects of the fourth vehicle lamp 2000 deviating from the third vehicle lamp 1000 will be described. Incidentally, the description of the third vehicle lamp 1000 also applies correspondingly to the fourth vehicle lamp 2000.

The fourth vehicle lamp 2000 has a light-emitting device 2100 configured to emit light. For this purpose, the light-emitting component 2100 comprises a plurality of first optoelectronic semiconductor chips 2110 and a plurality of second optoelectronic semiconductor chips 2120 Light-emitting component 2100 has a planar or parallelepiped light guide 2130. The first optoelectronic semiconductor chip 2110 and the second op ^¬ toelektronischen semiconductor chips 2120 are 2140 of the light guide 2130 disposed on side surfaces (outer edges) so that light emitted by the first opto-electronic semiconductor chip 2110 and the second optoelectronic semiconductor chip 2120 of electromagnetic radiation into the light guide 2130 is ^¬ coupled and a flat emission side 2101 of the light guide 2130 can be emitted.

In the illustrated example in Figure 10, the light emitting device 2100, the first optoelectronic semiconducting ^¬ terchips 2110 are arranged along an oriented parallel to a longitudinal direction 2001, the fourth vehicle lamp 2000 side surface 2140 of the light guide 2130th The second optoelectronic semiconductor chips 2120 are arranged on perpendicularly oriented side surfaces 2140 of the optical waveguide 2130. However, the on ^¬ arrangement of the first optoelectronic semiconductor chips 2110 and the second optoelectronic semiconductor chips in 2120 may also be chosen differently.

Preferably, the first optoelectronic semiconductor chips 2110 and the second optoelectronic semiconductor chips 2120 can be switched on and off independently of one another and also individually. The first optoelectronic semiconductor chips 2110 are configured to emit light having a wavelength from a first spectral range, for example blue light. The second optoelectronic semiconductor chips 2120 are designed to emit light having a wavelength from a second, longer wavelength spectral range, for example red light.

The fourth vehicle lamp 2000 further includes a Abdeckan ^¬ order 2200, which is arranged in front of the radiation face 2101 of the light-emitting device 2100 ^¬ fourth vehicle lamp 2000th Cover assembly 2200 is shown in exploded view in FIG. Actually, the components are However, the cover assembly 2200 connected areally.

The cover assembly 2200 includes a light absorbing element 2220, a wavelength converting element 2230, and a protective layer 2240. The wavelength converting element 2230 is disposed between the light absorbing element 2220 and the protective layer 2240. The light-absorbing member 2220 is on the light emitting device arranged 2100. ^¬ side facing the cover assembly 2200th The protective layer 2240 is at that of the light-emitting

Component 2100 opposite side of the cover 2200 arranged.

In contrast to the cover assembly 1200 of the third vehicle lamp 1000, the cover assembly 2200 of the fourth vehicle lamp 2000 has no diffuser plate 1210. Such a diffuser plate is not erfor ^¬ sary in the cover assembly 2200, since the light guide 2130 of the light emitting device 2100 can reasonably ensure a homogeneity and / or an isotropy of radiated by the light emitting device 2100 already light. Nevertheless, the

Cover assembly 2200 will of course be equipped with a diffuser plate. The protective layer 2240 of the cover assembly 2200 may optionally be omitted.

The light-absorbing element 2220 of the cover assembly 2200 has one or more recesses 2221 and corresponds in structure and function to the light-absorbing element 1220 of the cover assembly 1200 of the third vehicle lamp 1000. The wavelength-converting element 2230 of the cover assembly 2200 corresponds in construction and operation to the wavelength-converting element 1230 the cover assembly 1200 of the third vehicle lamp 1000.

The invention has been further illustrated and described with reference to the preferred embodiments. However, the invention is not limited to the disclosed examples. Much more From this, other variations can be derived by those skilled in the art without departing from the scope of the invention.
