Abstract

An arrangement of headlight lenses for a vehicle headlight, each headlight lens having a monolithic body of transparent material, which monolithic body includes at least one light entry face, a light passage section, and at least one optically operative light exit face.

First claim

The invention claimed is:

1. Vehicle headlight including
a first light source,
a first headlight lens comprising a first monolithic body of transparent material, the first monolithic body including
a first light passage section including a first optically operative light exit face, and
a first light tunnel comprising a first light entry face, wherein the first light tunnel passes over, via a first bend, into the first light passage section for imaging the first bend as a light-dark-boundary by means of light irradiated from the first light source into the first light entry face of the first headlight lens, and
an additional light source for irradiating light directly into the first light passage section.

2. Vehicle headlight including
a first light source,
at least a second light source,
a first headlight lens comprising a first monolithic body of transparent material, the first monolithic body including
a first light passage section including a first optically operative light exit face, and
a first light tunnel comprising a first light entry face, wherein the first light tunnel passes over, via a first bend, into the first light passage section for imaging the first bend as a light-dark-boundary by means of light irradiated from the first light source into the first light entry face of the first headlight lens, and
at least a second headlight lens comprising a second monolithic body of transparent material, the second monolithic body including
a second light passage section including a second optically operative light exit face, and
a second light tunnel comprising a second light entry face, wherein the second light tunnel passes over, via a second bend, into the second light passage section for imaging the second bend as a light-dark-boundary by means of light irradiated from the second light source into the second light entry face of the second headlight lens, wherein the second headlight lens comprises an optical axis which is inclined with respect to an optical axis of the first headlight lens by at least 0.5°.

3. The vehicle headlight of claim 2 , further comprising:
at least a third light source, and
at least a third headlight lens comprising a third monolithic body of transparent material, the third monolithic body including
a third light passage section including a third optically operative light exit face, and
a third light tunnel comprising a third light entry face, wherein the third light tunnel passes over, via a third bend, into the third light passage section for imaging the third bend as a light-dark-boundary by means of light irradiated from the third light source into the third light entry face of the third headlight lens, wherein the third headlight lens comprises an optical axis which is inclined with respect to said optical axis of the first headlight lens by at least 0.5°.

4. The vehicle headlight of claim 3 , wherein said optical axis of the third headlight lens is inclined with respect to said optical axis of the second headlight lens by at least 0.5°.

5. The vehicle headlight of claim 4 , further comprising
at least a fourth light source, and
at least a fourth headlight lens comprising a fourth monolithic body of transparent material, the fourth monolithic body including
a fourth light passage section including a fourth optically operative light exit face, and a fourth light tunnel comprising a fourth light entry face, wherein the fourth light tunnel passes over, via a fourth bend, into the fourth light passage section for imaging the fourth bend as a light-dark-boundary by means of light irradiated from the fourth light source into the fourth light entry face of the fourth headlight lens, wherein the fourth headlight lens comprises an optical axis which is inclined with respect to said optical axis of the first headlight lens by at least 0.5°.

6. The vehicle headlight of claim 5 , wherein said optical axis of the fourth headlight lens is inclined with respect to said optical axis of the second headlight lens by at least 0.5°.

7. The vehicle headlight of claim 6 , wherein said optical axis of the fourth headlight lens is inclined with respect to said optical axis of the third headlight lens by at least 0.5°.

8. The vehicle headlight of claim 6 , further comprising an additional light source for irradiating light into said first light tunnel.

9. The vehicle headlight of claim 8 , further comprising an additional light source for irradiating light into said second light tunnel.

10. The vehicle headlight of claim 9 , further comprising an additional light source for irradiating light into said third light tunnel.

11. The vehicle headlight of claim 10 , further comprising an additional light source for irradiating light into said fourth light tunnel.

12. The vehicle headlight of claim 11 , further comprising an additional light source for irradiating light directly into the first light passage section.

13. The vehicle headlight of claim 2 , further comprising an additional light source for irradiating light into a surface of the first light passage section.

14. The vehicle headlight of claim 13 , wherein light is irradiated, by means of the additional light source, above the light-dark-boundary.

15. The vehicle headlight of claim 13 , further comprising an additional light source for irradiating light into a surface of the second light passage section.

16. The vehicle headlight of claim 2 , further comprising a first corner light source arranged to the left of an optical axis of the first light tunnel.

17. The vehicle headlight of claim 16 , further comprising a second corner light source arranged to the right of the optical axis of the first light tunnel.

18. The vehicle headlight of claim 17 , further comprising a third corner light source arranged to the left of an optical axis of the second light tunnel.

19. The vehicle headlight of claim 18 , further comprising a fourth corner light source arranged to the right of the optical axis of the second light tunnel.

20. The vehicle headlight of claim 18 , further comprising a partial light source arranged below the light tunnel of the first headlight lens.

21. The vehicle headlight of claim 2 , further comprising a third light source arranged below the first light tunnel.

22. The vehicle headlight of claim 21 , further comprising a fourth light source arranged below the second light tunnel.

23. The vehicle headlight of claim 2 , wherein the optical axis which is inclined with respect to an optical axis of the first headlight lens by at least 0.50 is inclined with respect to a vertical plane.
