Definitions
- the invention relates to a lighting and signaling device for vehicles or aircraft according to the generic features of claim 1.
- a generic lighting and signaling device is known from DE 196 13 211 AI.
- This device has a light source, the light of which is focused into an optical rod.
- reflective facets couple light from the rod and guide it to the desired lighting field via optical lenses.
- the longitudinal axis of the light guide forms an acute angle to the facets, the inclination of the facets being dimensioned such that total reflection occurs on the facets.
- the unpublished DE 199 31 008 discloses how changes in the light distribution can be achieved.
- the light transmission controllable elements are conceivable, which are attached, for example, between the light source and rod or in front of the respective lens.
- the light is deflected or passed through, so that the light distribution area on the street is changed in this way.
- the light-controlling element is inserted at an oblique angle in the part of the light guide that illuminates the facet.
- the light-controlling element interrupts the light guide rod by gaps with a small distance.
- a new facet is formed, at which the light is directed in a different direction by total reflection.
- the column is closed by attaching the element to the light guide rod on both sides. Since that light-controlling element has an optical density similar to that of the light guide, interface reflection no longer occurs. The light can pass through the element undiminished and illuminate the original facet.
- a disadvantage of this type of signal and lighting device is that it is difficult to make an optical contact.
- a connecting medium is usually required, which connects the two light guides so closely that an optical contact arises.
- the light guide rods are made of elastic material so that they can be pressed against each other easily and thus an optical contact is created.
- the object of the invention is to improve a compact headlamp with variable light distribution so that the light distribution is easy to implement.
- the object is characterized by the features of
- Claim 1 solved. Advantageous training and further education of the
- a major advantage of these configurations is that in a headlamp with light guide technology, a variable ⁇ light distribution is achieved in a simple manner, with light being decoupled from one light guide rod and recoupling into another light guide rod and thus a variable light distribution of the headlight light is realized.
- the light intensity and the color can also be changed by suitable arrangements.
- FIG. 1 shows a schematic illustration of a vehicle lamp unit with a light guide system
- 2 shows a section of an optical light guide rod with a translationally connectable light guide rod
- Fig. 3 shows a detail of an optical light guide rod with a translationally movable coupling element.
- FIG. 1 shows a schematic illustration of a vehicle lamp unit 1 with a light guide system, in particular for a headlight of a vehicle or aircraft, the vehicle lamp device 1 having a light source 6 which couples the light into an optical rod 2.
- the light is passed on from the optical rod 2 constructed from light guides 7, is reflected on the facets 3, the facets interacting with optical lenses 15, which are arranged at the exit of a light guide 7 in the path of the elementary light bundles reflected by the facets 3, and then emerges from the light guides 7.
- the light-controlling elements 5 can be integrated in the light guide 7 and / or connect directly on or to the facet 3. Depending on the switching state of the light-controlling element 5, light is deflected or passed through, so that the light distribution area on the street is changed in this way.
- the various light distribution areas form the headlight.
- a coupling element can be inserted into the beam path of the decoupled beam to recouple the beam. With the correct wiring, different headlight settings can be realized.
- This control mechanism enables situation-based light distribution control on the street. A cornering light that adapts to the road in accordance with the curve or a headlight control system that uses location information from satellite navigation systems can thus be implemented simply and precisely.
- a control unit is provided to control the headlight light, which controls the light transmittance and light absorption or reflection controls the light-controlling elements so that a predetermined light distribution on the street is created.
- the 2 shows a section of an optical light guide rod 7 with a translationally connectable light guide rod 5.
- the two light guide rods 5, 7 have boundary surfaces which do not have optical coupling of the light guide rod 7 into the second light guide rod 5 via an optical contact between the two light guide rods 5.7 is done.
- the two light guide rods 5, 7 do not touch.
- the light passes through translatory parallel displacement of one of the two light guide rods 5, 7 as a coupling element in the beam path of the beam coupled out from the other light guide rod.
- the light couples out of the first light guide rod 7 and enters the air or the medium surrounding the light guide rod 7 before it hits the second light guide rod 5 again and couples it into the second light guide rod 5.
- the light passes through the first light guide rod 7 until it meets the inclination that has the angle of total reflection. At this inclination, the light is deflected downward in the z direction and, after passing through the light guide, leaves the first light guide rod 7 and enters the medium surrounding the light guide rod 7. The light moves in this medium until it strikes the second light guide rod 5, into which it couples and is reflected again at an inclination that has the angle of total reflection in the desired direction of propagation in which it spreads.
- the second light guide rod 5 is arranged spatially offset and is moved translationally under or next to the first light guide rod 7 until the light coupled out of the first light guide rod 7 can be coupled back into the first light guide rod 7. The second light guide rod 5 then transmits light.
- the light intensity is adjusted by the size of the overlapping areas.
- 3 shows a section of an optical light guide rod 7 with a coupling element 11 which can be moved in translation.
- the two light guide rods 5, 7 are arranged in a fixed position, the light coupled out of the light guide rod 7 being reflected by a coupling element 11 and being coupled into the light guide rod 5, whereby the light passes through translatory parallel displacement of the coupling element 11.
- the two light guide rods 5, 7 are fixedly arranged at a suitable distance from one another.
- the coupling element 11 can be moved into the light path in such a way that the light coupled out of the first light guide rod 7 is reflected via the coupling element 11 into the second light guide rod 5.
- the first light guide rod 7 has an inclined surface which reflects the light downwards where the light leaves the light guide rod 7. If the coupling element 11 is located in this beam path, the light is coupled into the coupling element 11 and reflected so that the light emerges again at another point and can be coupled into the second light guide rod 5. In the second light guide rod 5, the light is still reflected in the desired direction of propagation and then passed on.
- At least two light guide rods 5, 7 and at least one coupling element 11 are provided here. However, more coupling elements can also be provided along the two light guide rods, or more than two light guide rods and several coupling elements 11 are provided.
- a change in the color of the headlight light can be achieved by coloring the second light guide rod.
- the second light guide rod is then colored in accordance with the desired light color.
