Abstract

An optical module of a lighting and/or signaling device of a motor vehicle In one embodiment, the optical module comprises a support that supports an optical lens and a heat exchanger, with the support connecting the optical lens to the heat exchanger.

First claim

What is claimed is:

1. An optical module for use in a lighting device of a motor vehicle, said optical module comprising:
a support;
an optical lens; and
a heat exchanger wherein said optical lens and said heat exchanger are attached to said support and in that said support connects said optical lens to said heat exchanger;
wherein said optical module comprises at least one reflector positioned relative to said support and attached to said support beneath said support, between said support and said heat exchanger;
wherein said support comprises support positioning means that interact with attachment means provided on said optical lens, said heat exchanger and said at least one reflector so that a chain of dimensions associated with mounting said optical lens, said heat exchanger and said at least one reflector passes to less than all of them;
wherein said support positioning means and said attachment means cooperate to couple said optical lens, said heat exchanger and said at least one reflector being directly to said support.

2. The optical module as claimed in claim 1 , wherein said lighting device further comprises a casing, said support being mounted on an inside of said casing.

3. The optical module as claimed in claim 2 , wherein said support supports at least one of a fan, at least one light reflector, a folder or a means for channeling air.

4. The optical module as claimed in claim 1 , wherein said support supports at least one of a fan, at least one light reflector, a folder or a means for channeling air.

5. The optical module as claimed in claim 4 , wherein said support connects said heat exchanger to at least one of said fan, said at least one light reflector, said folder or said means for channeling air.

6. The optical module as claimed in claim 1 , wherein said support comprises means for positioning at least one of said optical lens, a fan, at least one light reflector, a folder or a heat exchanger, these means interacting with a second positioning means provided on at least one of said optical lens, on said fan, on said at least one light reflector, on said folder or on said heat exchanger.

7. The optical module as claimed in claim 1 , wherein said optical module comprises a first light source and a second light source for performing two distinct functions of lighting and of signaling, respectively.

8. The optical module as claimed in claim 7 , wherein said first light source performs a lighting function of a high beam type in interaction with said second light source and in that said second light source performs a lighting function of a low beam type.

9. The optical module as claimed in claim 1 , wherein said lighting device further comprises a casing, said support being rotatably mounted on an inside of said casing.

10. The optical module as claimed in claim 9 , wherein said optical module further comprises a base attached to said casing and further comprising a first articulation means secured to said support so as to allow said support to rotate relative to said casing.

11. The optical module as claimed in claim 1 , wherein said optical lens is positioned on and attached to a front portion of said support and in that said heat exchanger is positioned on and attached to said support beneath the latter.

12. The optical module as claimed in claim 11 , wherein said optical module comprises a first light source and a second light source which are positioned on and attached to said heat exchanger.

13. The optical module as claimed in claim 11 , wherein said optical module comprises a folder positioned on and attached to said support.

14. The optical module as claimed in claim 11 , wherein said optical module comprises a fan positioned on said support.

15. A lighting device comprising an optical module as claimed in claim 1 .

16. The optical module as claimed in claim 1 , wherein said support comprises a positioner for positioning at least one of said optical lens, a fan, at least one light reflector, a folder or a heat exchanger, said positioner interacting with a second positioner provided on at least one of said optical lens, on said fan, on said at least one light reflector, on said folder or on said heat exchanger.

17. The optical module as claimed in claim 16 , wherein said optical module comprises a first light source and a second light source for performing two distinct functions of lighting and of signaling, respectively.

18. The optical module as claimed in claim 17 , wherein said first light source is performs a lighting function of a high beam type in interaction with said second light source and in that said second light source performs a lighting function of a low beam type.

19. The optical module as claimed in claim 1 , wherein said lighting device is a signaling device.

20. The optical module as claimed in claim 1 , wherein said lighting device produces at least one of a high beam, a low beam or a fog light function.

21. The optical module as claimed in claim 1 , wherein said support supports a plurality of a fan, at least one light reflector, a folder or a means for channeling air.

22. The optical module as claimed in claim 1 , wherein said support further comprises means for positioning said optical lens, a fan, at least one light reflector, a folder or a heat exchanger, these means interacting with a second positioning means provided on said optical lens, on said fan, on said at least one light reflector, on said folder or on said heat exchanger.

23. The optical module as claimed in claim 1 , wherein said support supports a fan and at least one light reflector.

24. The optical module as claimed in claim 1 , wherein said support supports a fan and a folder.

25. The optical module as claimed in claim 1 , wherein said support supports a fan and a means for channeling air.

26. The optical module as claimed in claim 1 , wherein said support supports a reflector and a folder.

27. The optical module as claimed in claim 1 , wherein said support supports a reflector and a means for channeling air.

28. The optical module as claimed in claim 1 , wherein said support supports a folder and a means for channeling air.

29. The optical module as claimed in claim 1 , wherein said support supports each of a fan, at least one light reflector, a folder or a means for channeling air.

30. An optical module for use in a lighting device of a motor vehicle, said optical module comprising:
a support;
an optical lens; and
a heat exchanger wherein said optical lens and said heat exchanger are attached to said support and in that said support connects said optical lens to said heat exchanger;
wherein said optical lens is positioned on and attached to a front portion of said support and in that said heat exchanger is positioned on and attached to said support beneath the latter;
