Abstract

A motor vehicle light includes an optical waveguide system and a reflector. The optical waveguide system is arranged in the focal line of the reflector and is configured to project a plurality of light beams onto the reflector to generate a light signature having a plurality of parallel light beams emitting from the motor vehicle light. The motor vehicle light may include a housing with a transparent cover lens in order to protect the optical waveguide system from environmental influences such as sunlight and mechanical stresses.

First claim

What is claimed is:

A motor vehicle light comprising: an optical waveguide system having an optical waveguide element, the optical waveguide system configured with a light source on an end face of the optical waveguide element, a reflector including a reflective surface having a focal line, and a lateral region extending from the reflective surface and supporting the optical waveguide system, wherein the optical waveguide system is arranged in the focal line of the reflector and is configured to project a plurality of light beams through the optical waveguide system and reflect off the reflector to generate a light signature having a plurality of parallel light beams emitting from the motor vehicle light.

2. The motor vehicle light according to claim 1 , wherein the reflective surface comprises a shell-shaped structure having a two-dimensional curvature.

3. The motor vehicle light according to claim 1 , wherein the reflector comprises a one-piece component.

4. The motor vehicle light according to claim 1 , wherein the reflective surface comprises a metallized surface.

5. The motor vehicle light according to claim 1 , wherein the reflector comprises an injection-molded reflector.

6. The motor vehicle light according to claim 1 , wherein the reflector comprises a polymeric reflector.

7. The motor vehicle light according to claim 1 , wherein the lateral region further comprises an enclosure for the optical waveguide system, wherein the enclosure is arranged along the focal line of the reflector.

8. The motor vehicle light according to claim 1 , wherein the focal line is a straight focal line.

9. The motor vehicle light according to claim 1 , wherein the optical waveguide system comprises a plurality of light sources, each light source configured to project a light beam through the optical waveguide system and reflect off the reflector.

10. The motor vehicle light according to claim 1 , wherein the optical waveguide system comprises a diffusion element.

11. The motor vehicle light according to claim 1 , wherein the optical waveguide system comprises a linear waveguide system.

12. The motor vehicle light according to claim 1 , wherein the optical waveguide system comprises one or more LED.

13. A motor vehicle light comprising:
a reflector including a shell-shaped structure having a two-dimensional curvature and a reflective surface defining a focal line, a lateral region extending from the reflective surface and an enclosure supporting an optical waveguide system, wherein the enclosure is arranged along the focal line of the reflector; and
a linear waveguide system arranged in the focal line of the reflector and having a plurality of light sources, each light source configured to project a light beam through the optical waveguide system and reflect off the reflector to generate a light signature having a plurality of parallel light beams emitting from the motor vehicle light.

14. The motor vehicle light according to claim 13 , wherein the reflective surface comprises a metallized surface.

15. The motor vehicle light according to claim 13 , wherein the reflector comprises a one-piece component.

16. The motor vehicle light according to claim 13 , wherein the optical waveguide system comprises a diffusion element.

17. The motor vehicle light according to claim 13 , wherein the focal line is a straight focal line.

18. The motor vehicle light according to claim 17 , wherein the optical waveguide system comprises a linear waveguide system.

19. The motor vehicle light according to claim 13 , wherein the plurality of light sources comprises one or more LED.

20. A motor vehicle light comprising:
a reflector that has a two-dimensional curvature, a reflective surface defining a focal line, and a lateral region extending from the reflective surface;
an enclosure disposed in the lateral region and supporting the optical waveguide system, wherein the enclosure is arranged along the focal line of the reflector; and
an optical waveguide system arranged in the focal line of the reflector and having an optical waveguide, a diffusion element, and a light source;
wherein the light source is configured to project a light beam through the optical waveguide system and reflect off the reflector to generate a light signature having a plurality of parallel light beams emitting from the motor vehicle light.
