Abstract

A vehicle headlamp includes a first light source, at least one second light source and an integrally designed, transparent shaped part. The shaped part includes a first optical structure for orienting light radiated by the first light source and at least one second optical structure for orienting light radiated by the second light source. The first optical structure and the second optical structure each have a continuously curved surface or a continuous, curved surface with an extent of at least in each case half a centimeter, in particular one centimeter, in two orthogonal directions.

Claims (41)

1. A device comprising:

a vehicle headlight comprising:

a first light source;

at least a second light source; and

a transparent shaped part configured in one piece, the transparent shaped part comprising:

a first convex lens for the direction of light emitted by the first light source; and

at least a second lens selected from the group consisting of (a) convex lens and (b) concave lens for the direction of light emitted by the second light source,

wherein a substantial part of the light which is emitted by the first light source and passes through the transparent shaped part emerges from the first lens,

wherein the first light source in conjunction with the first convex lens directs light in a different direction from the second light source in conjunction with the second lens, and

wherein the first light source and the first convex lens are configured to form a dipped-beam light.

2. The device according to claim 1 , wherein a substantial part of the light which is emitted by the second light source and passes through the transparent shaped part emerges from the second lens.

3. The device according to claim 1 , wherein the second light source comprises an LED.

4. The device according to claim 1 , further comprising:

at least a third light source, wherein the shaped part has at least a third lens for the direction of light emitted by the third light source.

5. The device according to claim 1 , wherein the first lens is configured to image a bright-dark boundary.

6. The device according to claim 1 , further comprising:

a light shield, wherein an edge of the light shield can be imaged as a bright-dark boundary by means of the first lens.

7. The device according to claim 1 , wherein the transparent shaped part substantially consists of glass.

8. The device according to claim 1 , wherein the transparent shaped part forms an outer part of the vehicle headlight.

9. The device according to claim 1 , wherein the first lens and the second lens each extend at least one centimeter in two orthogonal directions.

10. A device comprising:

a vehicle headlight comprising:

a first light source;

at least a second light source; and

a transparent shaped part configured in one piece, the transparent shaped part comprising:

a first convex lens for the direction of light emitted by the first light source; and

at least a second lens selected from the group consisting of (a) convex lens and (b) concave lens for the direction of light emitted by the second light source,

wherein a substantial part of the light which is emitted by the first light source and passes through the transparent shaped part emerges from the first lens,

wherein the first light source in conjunction with the first convex lens directs light in a different direction from the second light source in conjunction with the second lens,

wherein the first light source and the first convex lens are configured to form a dipped-beam light, and

wherein the second light source and the second lens are configured to form a static cornering light.

11. The device according to claim 10 , wherein a substantial part of the light which is emitted by the second light source and passes through the transparent shaped part emerges from the second lens.

12. The device according to claim 10 , wherein the second light source comprises an LED.

13. The device according to claim 10 , further comprising:

at least a third light source, wherein the shaped part has at least a third lens for the direction of light emitted by the third light source.

14. The device according to claim 10 , wherein the first lens is configured to image a bright-dark boundary.

15. The device according to claim 10 , further comprising:

a light shield, wherein an edge of the light shield can be imaged as a bright-dark boundary by means of the first lens.

16. The device according to claim 10 , wherein the transparent shaped part substantially consists of glass.

17. The device according to claim 10 , wherein the transparent shaped part forms an outer part of the vehicle headlight.

18. The device according to claim 10 , wherein the first lens and the second lens each extend at least one centimeter in two orthogonal directions.
