Abstract

A light module for a motor vehicle including a light source, an electronic support, a driver device driving the electrical power supply of the one light source arranged on the electronic support, a heatsink including an obviously in which the driver device is housed, characterized in that the light source is fixed onto the heatsink.

Claims (31)

1. A light module for a motor vehicle comprising:

a light source;

an electronic support;

a driver device arranged on the electronic support and configured to drive an electrical supply of the light source; and

a heatsink comprising a plurality of orifices and a raised fixing zone wherein the light source is fixed onto the raised fixing zone of the heatsink; and

an optical module adapted to cooperate with light rays emitted by the light source of the light module, the optical module comprising a plurality of posts configured to engage the plurality of orifices respectively, such that the light source is optically coupled to the optical module.

2. The light module of claim 1 , wherein the electronic support comprises a printed circuit board.

3. The light module of claim 2 , wherein the printed circuit board is electrically connected to the light source.

4. The light module of claim 3 , further comprising a conductor having a first end attached to the printed circuit board, and a second end attached to the light source such that the printed circuit board is electrically connected to the light source.

5. The light module of claim 4 , wherein the light source is an LED.

6. The light module of claim 1 , wherein the heat sink comprises a base plate having a face, and the raised fixing zone is raised with respect to the face of the base plate.

7. The light module of claim 6 , wherein the heat sink further comprises at least one lateral face extending at an angle from the base plate in a direction away from the face of the base plate.

8. The light module of claim 6 , wherein the heat sink is adapted to be pressed onto the electrical support.

9. The light module of claim 8 , wherein:

the heat sink comprises a plurality of protrusions extending from the face of the base plate;

the electrical support includes a plurality of holes each configured to receive a respective one of the plurality of protrusions such that heat sink is pressed onto the electrical support.

10. The light module of claim 6 , wherein:

the plurality of posts extend from the optical module; and

the plurality of orifices each extending through the base plate and configured to receive a respective one of the plurality of posts to couple the optical module to the heat sink such that the light source is optically coupled to the optical module.

11. The light module of claim 10 , wherein the optical module is a reflector.

12. The light module of claim 6 , wherein the base plate comprises a first opening extending therethrough and the electrical support comprises a second opening extending therethrough, the light module further comprising a fastening element extending through the first opening and the second opening to couple the heat sink and electrical support to the optical element such that the light source is optically coupled to the optical module.

13. The light module of claim 12 , wherein the optical module is an optical reflector configured to receive light rays from the light source.

14. The light module of claim 13 , wherein the fastening element is a separate screw.

15. The light module of claim 13 , wherein the fastening element is a protrusion extending from the optical module.

16. The light nodule of claim 1 , wherein the raised fixing zone is an integral part of the heat sink.

17. The light module of claim 1 , wherein the heat sink comprises a metal plate having a face, and the fixing zone is a stamped portion of the metal plate.

18. The light module of claim 17 , wherein the metal plate further comprises at least one bend that forms at least one respective portion of the heat sink that extends at an angle with respect to the face to form a lateral face.

19. The light module of claim 18 , wherein:

the at least one respective portion extends from the face at an angle of approximately 90 degrees, and

the at least one respective portion extends in a first direction away from the face of the base plate.

20. The light module of claim 19 , wherein the electric support is in contact with the face of the base plate.
