Abstract

A lighting module for automobile vehicles, including at least one optical module adapted to produce a first cut-off beam; a support plate for a heatsink; the heatsink adapted to receive the optical module; wherein the support plate includes a first surface; the heatsink includes rotational adjustment means adapted to enter into contact with the first surface of the support plate; and to pivot about a particular rotation axis so as to position the first cut-off beam produced by the optical module at a reference position.

First claim

What is claimed is:

1. A lighting module for automobile vehicles (V), including:
at least one optical module adapted to produce a first cut-off beam;
a support plate for a heatsink;
said heatsink adapted to receive said at least one optical module;

wherein:
said support plate includes a first surface;
said heatsink includes rotational adjustment means adapted:
to enter into contact with said first surface of said support plate; and
to pivot about a particular rotation axis (Ax) so as to position said first cut-off beam produced by said at least one optical module at a reference position (P).

2. The lighting module according to claim 1 , wherein said first cut-off beam is a cut-off beam at least one portion of which is flat.

3. The lighting module according to claim 1 , wherein said rotational adjustment means include two fins for guiding said heatsink, notably distributed on respective opposite sides of cooling fins.

4. The lighting module according to claim 3 , wherein said first surface and said rotational adjustment means are of cylindrical shape with a circular section.

5. The lighting module according to claim 1 , wherein:
said support plate further includes at least one slide; and
said heatsink further includes a male pivot pin adapted to be inserted in said at least one slide of said support plate.

6. The lighting module according to claim 1 , wherein said heatsink further includes a first interface area adapted to cooperate with an adjustment tool so as to actuate the rotation of said rotational adjustment means about said rotation axis (Ax).

7. The lighting module according to claim 6 , wherein:
said support plate further includes a surface provided with an aperture situated in front of said first surface; and
said first interface area is disposed at a level of said aperture after the contact between said rotational adjustment means of said heatsink and said first surface of said support plate.

8. The lighting module according to claim 6 , wherein said heatsink further includes an additional interface area adapted to cooperate with an adjustment tool so as to actuate the rotation of said rotational adjustment means about said rotation axis (Ax).

9. The lighting module according to claim 1 , wherein:
said support plate further includes a screw pillar; and
a fin for guiding the said heatsink is further adapted to receive fixing means inserted in said screw pillar of said support plate.

10. The lighting module according to claim 1 , wherein said support plate further includes a second surface facing said first surface, said first surface and said second surface forming a groove for guiding said rotational adjustment means for rotational adjustment of said heatsink.

11. The lighting module according to claim 1 , wherein said support plate is further adapted to receive an additional optical module adapted to produce a second cut-off beam.

12. The lighting module according to claim 11 , wherein said second cut-off beam is a cut-off beam a portion of which is oblique.

13. The lighting module according to claim 11 , wherein said reference position (P) corresponds to a horizontal part of said second cut-off beam.

14. The lighting module according to claim 11 , wherein said first cut-off beam and said second cut-off beam are adapted to provide conjointly a first low beam photometric function (f1).

15. The lighting device for automobile vehicles (V) including a lighting module according to claim 1 .

16. The lighting module according to claim 2 , wherein said rotational adjustment means include two fins for guiding said heatsink, notably distributed on respective opposite sides of cooling fins.

17. The lighting module according to claim 2 , wherein:
said support plate further includes at least one slide; and
said heatsink further includes a male pivot pin adapted to be inserted in said at least one slide of said support plate.

18. The lighting module according to claim 2 , wherein said heatsink further includes a first interface area adapted to cooperate with an adjustment tool so as to actuate the rotation of said rotational adjustment means about said rotation axis (Ax).

19. The lighting module according to claim 7 , wherein said heatsink further includes an additional interface area adapted to cooperate with an adjustment tool so as to actuate the rotation of said rotational adjustment means about said rotation axis (Ax).

20. The lighting module according to claim 2 , wherein:
said support plate further includes a screw pillar; and
a fin for guiding said heatsink is further adapted to receive fixing means inserted in said screw pillar of said support plate.
