Abstract

A motor vehicle comprising a headlight lens having a monolithic body of transparent material, the monolithic body including 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. A motor vehicle including:
at least four wheels;
a front bumper;
a first light source; and
a first headlight lens integrated in the bumper within a central third thereof, wherein the first headlight lens comprises a first monolithic body consisting of transparent material, the first monolithic body including:
a first light passage section including at least a first optically operative light exit face; and
a first light tunnel comprising at least a first light entry face,
wherein the first light tunnel is adjacent to the first light passage section,
wherein the first light tunnel transitions, via a first bend, into the first light passage section and the first light passage section projects the first bend as a light-dark-boundary from light irradiated from the first light source into the first light entry face.

2. The motor vehicle of claim 1 , further comprising:
a second headlight lens being integrated in said bumper within the central third thereof, which second headlight lens comprises a second monolithic body of transparent material, the second monolithic body including:
a second light passage section including at least a second optically operative light exit face; and
a second light tunnel comprising at least 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.

3. The motor vehicle of claim 2 , further comprising:
a third headlight lens being integrated in said bumper within the central third thereof, which third headlight lens comprises a third monolithic body of transparent material, the third monolithic body including:
a third light passage section including at least a third optically operative light exit face; and
a third light tunnel comprising at least 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.

4. The motor vehicle of claim 3 , further comprising:
a fourth headlight lens being integrated in said bumper within the central third thereof, which fourth headlight lens comprises a fourth monolithic body of transparent material, the fourth monolithic body including:
a fourth light passage section including at least a fourth optically operative light exit face; and
a fourth light tunnel comprising at least 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.

5. The motor vehicle of claim 4 , wherein the forth headlight lens comprises an optical axis, which is inclined with respect to an optical axis of the first headlight lens.

6. The motor vehicle of claim 5 , wherein the optical axis of the forth headlight lens is inclined with respect to an optical axis of the second headlight lens.

7. The motor vehicle of claim 6 , wherein the optical axis of the forth headlight lens is inclined with respect to an optical axis of the third headlight lens.

8. The motor vehicle of claim 2 , wherein the second headlight lens comprises an optical axis, which is inclined with respect to an optical axis of the first headlight lens.

9. The motor vehicle of claim 3 , wherein the third headlight lens comprises an optical axis, which is inclined with respect to an optical axis of the first headlight lens.

10. The motor vehicle of claim 9 , wherein the optical axis of the third headlight lens is inclined with respect to an optical axis of the second headlight lens.

11. The motor vehicle of claim 1 , further comprising: a first additional light source for irradiating light into said light tunnel of the first headlight lens.

12. The motor vehicle of claim 11 , further comprising: a second additional light source for irradiating light directly into the light passage section of the first headlight lens.

13. The motor vehicle of claim 1 , further comprising: an additional light source for irradiating light directly into the light passage section of the first headlight lens.

14. The motor vehicle of claim 1 , further comprising: an additional light source for irradiating light into a surface of the light passage section of the first headlight lens.

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

16. The motor vehicle of claim 1 , further comprising: a first corner light source arranged to the left of an optical axis of the light tunnel of the first headlight lens.

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

18. The motor vehicle of claim 17 , further comprising: a partial light source arranged below the light tunnel of the first headlight lens.

19. The motor vehicle of claim 1 , further comprising: a partial light source arranged below the light tunnel of the first headlight lens.

20. The motor vehicle of claim 1 , wherein the first bend causes the light-dark boundary to be correspondingly bent.

21. The motor vehicle of claim 1 , wherein the bend is a curved transition from the light tunnel into the light passage section and the bend is curved in two spatial directions.

22. The motor vehicle of claim 21 , wherein the bend is a continuous curved transition formed by blank molding.

23. A motor vehicle including:
at least four wheels;
a body;
a first light source; and
a first headlight lens being integrated in the body within a central third of a front of the motor vehicle, which first headlight lens comprises a first monolithic body consisting of transparent material, the first monolithic body including:
a first light passage section including at least a first optically operative light exit face; and
a first light tunnel comprising at least a first light entry face, wherein the first light tunnel transitions, via a first bend, into the first light passage section, the first light passage section projecting the first bend as a light-dark-boundary by means of light irradiated from the first light source into the first light entry face.

24. The motor vehicle of claim 23 , further comprising:
a second headlight lens being integrated in said body within the central third of the front of the motor vehicle, which second headlight lens comprises a second monolithic body of transparent material, the second monolithic body including:
a second light passage section including at least a second optically operative light exit face; and
a second light tunnel comprising at least 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.

25. The motor vehicle of claim 24 , further comprising:
a third headlight lens being integrated in said body within the central third of the front of the motor vehicle, which third
