Definitions
- the invention relates to a lampless signal element (e.g. signal button, toggle switch, rotary knob, slide switch), possibly in conjunction with a label, which assumes different positions with respect to a fixed housing part in different switching states.
- a lampless signal element e.g. signal button, toggle switch, rotary knob, slide switch
- a lampless signal button is already known, the switching state of which can be easily recognized by one or more light symbols (areas or inscriptions) and which does not require a lamp (DE-AS 20 32 839).
- a switch position mirrors redirect the ambient light falling laterally in a component of the switch button. In the other position, no light penetrates this component.
- the solution according to the invention it is possible to illuminate not only a signal button, but also other switching devices, such as toggle switches, rotary switches and slide switches or the like.
- the possibility of collecting light, in particular also diffuse light, and concentrating it on defined decoupling areas makes the signal element proposed according to the invention far superior to a system with mirrors in terms of its range of application and moves it close to active signal displays in terms of its recognizability.
- the display is easy to read both at dusk and in very bright ambient light, which is not the case for LEDs or glow lamps for this wide range.
- the integration of the fluorescent body in the actuating part has the advantage, since the actuating part is the movable part, that the lighting conditions can be changed in a simple manner.
- the integration of the fluorescent body in the housing makes it possible to achieve much larger collecting areas than can be carried out, for example, in the movable part of conventional switches.
- the fluorescent light is guided or coupled out via light guides. This enables lossless light guidance over areas that do not contribute to light collection.
- FIG. 1 denotes a translucent button housing, in which a disk-shaped fluorescent body 2 with decoupling points 3 is introduced. Embossed notches or printed pigments in the form of symbols (letters or numbers) can be provided as decoupling points. White, colored, fluorescent or phosphorescent particles can in turn be applied as pigments.
- the narrow sides of the fluorescent body 2 can be mirrored, which is indicated by the reference number 4.
- the rear wall of the signal button is mirrored or provided with a diffusely reflecting coating. At an opaque mask 6 is attached to the front of the fluorescent body, leaving only the decoupling points 3 free.
- the signal button is installed in a housing 7.
- the signal (lettering, for example "ON” / "OFF", symbols or the like) lights up.
- ambient light in FIG. 1 a strikes the plate-shaped fluorescent body 2 directly or via the mirror 5.
- This is a body with smooth, parallel surfaces, which is made of a transparent material with a refractive index n > 1 exists (eg PMMA) and contains a fluorescent dye.
- n refractive index 1 exists (eg PMMA) and contains a fluorescent dye.
- FIG. 2 denotes the transparent front (light guide) of a lampless signal button which is somewhat modified compared to FIG. 1.
- the light collecting device 2 is tubular, whose. rear side surfaces are provided with reflectors 4.
- the fluorescent light is reflected via the reflectors 9 in the light guide 8, which forms the front.
- the collected light is emitted to the front. So that no ambient light reaches the fluorescent body (through the transparent front plate 8) when the signal button is pressed in, a cover 6 adapted to this embodiment against ambient light is provided, as in FIG.
- the translucent housing 1, which can also be made like milk glass, primarily serves to protect the fluorescent body against scratching. In principle, the housing can be dispensed with.
- FIG. 3 shows a toggle switch with the axis of rotation 10, in which the fluorescent body is located in the actuating part.
- the light collected by the fluorescent body 2 is guided through the light guide 8 and leaves it at 3.
- the fluorescent body is folded into the housing 7 and the covers 6 prevent light from entering the transparent housing 1 :. Accordingly, no light emerges at 3 in this switch position.
- Changes in the geometric shape and construction are possible when only care is taken that in each case one light entry opening is open only in a switching state, the or is covered in the other switching state esch g lossen.
- Figure 4a shows a rotary switch in plan view and Figure 4b in section.
- the reflectors 9 guide the fluorescent light into the light guide 8, so that it exits at 3.
- the housing parts designated 7 are opaque.
- the knob 11 is turned, for example by 90 °, the fluorescent bodies 2 disappear behind the opaque housing parts 7, so that they are not reached by the ambient light. Instead, the preferably differently colored fluorescent bodies 2 'are now illuminated by the ambient light. Instead of a division into 90 ° sections, any division is possible.
- a plurality of fluorescent bodies can also be connected in series in front of a light entry opening 1.
- FIG. 1 A plate-shaped fluorescent body 2 is applied to a slide 12. On one side, the collected fluorescent light is fed to the viewer via the light guide 8 and the decoupling point 3. The other sides are provided with reflectors 4. This figure shows the state in which the signal element is illuminated. If the slide is sunk to the right behind the opaque housing wall 7, the decoupling point 3 remains dark.
- FIG. 6 shows a push button in which several switch positions can be displayed.
- the Flu p reszenz Chemistry 2 is a part of the housing.
- the push button consists of opaque material 13 in which light guides 8a and 8b are provided. Reflectors 9 serve to guide the light. In the position shown, light emerges via the light guide 8a and the coupling-out point 3a, for example in a punctiform manner. In a middle position, in which the push button is pressed in so deeply that the light guide 8b is struck by the fluorescent light, light, for example in a ring, emerges via the decoupling point 3b. If the push button is pressed in further until the light guides are sunk into the housing, the decoupling point remains dark.
- FIG. 7a shows a toggle switch in section in a side view and in FIG. 7b in a top view.
- the fluorescent body 2 represents the cover plate.
- Light is thus coupled in in each switch position and light is coupled out once at the top and once at the bottom, depending on the switch position. Accordingly, the upper name lights up, e.g. "ON”, and once the lower name, e.g. "From to.
- Figure 8a shows a rotary switch in section and Figure 8b in plan view.
- the light collected by the fluorescent body p r 2 is deflected via the reflectors 9, passes the actuating part through the transparent window 81 and is coupled out via 3.
- the reflect gates 9 and the arrangement of transparent windows 81 let light through at different points.
- the slide switch shown again in two views in FIG. 9 has, for example, four switch positions A to D.
- the sectional view 9a is rotated by 90 ° with respect to the top view 9b.
- the generally translucent housing 1 of the actuating part carries a bar made of light guides 8 and opaque areas 13.
- a light guide 8 is located above the reflector 9 and is thereby illuminated from below with fluorescent light.
- the invention can be adapted to any shape.
