Abstract

A light module for a motor vehicle comprises at least one light source capable of emitting light rays, a support bearing the source, an electrical power supply cable of the source, an optical deflection element arranged so as to deflect the light rays emitted by this source to form a projected light beam at the output of the light module, and a guiding device for guiding the optical deflection element in rotation about an axis of rotation, in order to transversely shift the projected light beam. According to the invention, the support comprises a first part, bearing the light source, and the second part, between which there is inserted at least a part of the guiding device, and the cable passes through the rotation guiding device to be connected to said light source.

First claim

The invention claimed is:

1. Light module for a motor vehicle comprising
at least one light source capable of emitting light rays,
at least one support bearing said light source,
at least one electrical power supply cable of said at least one light source,
at least one optical deflection element arranged so as to deflect the light rays emitted by the at least one light source to form a projected light beam at the output of the light module,
a guiding device for guiding the optical deflection element in rotation about an axis of rotation, in order to transversely shift the projected light beam, characterized in that the support comprises a first part, bearing the light source, and a second part, between which there is inserted at least a part of the rotation guiding device of the optical deflection element and in that said at least one cable passes through the rotation guiding device to be connected to said light source.

2. Light module according to claim 1 , wherein the at least one cable comprises a first portion for connection to a control module, arranged at least partly in the second part of the support, a second intermediate portion, passing through the rotation guiding device, and a third portion for connection to the light source.

3. Light module according to claim 1 , wherein the at least one cable passes through the rotation guiding device substantially at the center thereof, so as to be centered on the axis of rotation.

4. Light module according to claim 1 , wherein the first part of the support has a first face bearing the light source, an opposite second face turned toward the second part of the support and a peripheral face axially linking the first and the second face.

5. Light module according to claim 2 , wherein the third portion of the at least one cable is arranged along the second face and against the peripheral face, such that the at least one cable is at least partially offset in this third portion relative to the axis of rotation of the optical deflection element.

6. Light module according to claim 5 , wherein an indentation is arranged at least on the second face to house the third portion of the at least one cable.

7. Light module according to claim 6 , wherein a flat is formed axially by machining the peripheral face, said at least one cable being pressed against said flat.

8. Light module according to claim 1 , wherein a support plate of the light source has a first face bearing the light source and a second face arranged against the first face of the first part of the support, said at least one cable being connected to a second face of the first support plate.

9. Light module according to claim 1 , wherein the light module comprises a guiding sleeve for the at least one cable fixed to the first part of the support.

10. Light module according to claim 9 , wherein the rotation guiding device consists of a stator secured to the second part of the support and of a rotor secured to the optical deflection element and configured to rotate about the stator.

11. Light module according to claim 10 , wherein at least the stator is pierced axially to allow the passage of the at least one electrical power supply cable of the light source.

12. Light module according to claim 11 , wherein the stator is gripped between the two parts of the support.

13. Light device, notably for lighting and/or signaling, comprising at least one light module according to claim 1 .

14. Light device according to claim 13 , wherein the light module comprises a casing defining, with an enclosing outer lens, a housing for receiving at least one light module.

15. Light module according to claim 2 , wherein the at least one cable passes through the rotation guiding device substantially at the center thereof, so as to be centered on the axis of rotation.

16. Light module according to claim 2 , wherein the first part of the support has a first face bearing the light source, an opposite second face turned toward the second part of the support and a peripheral face axially linking the first and the second face.

17. Light module according to claim 4 , wherein the third portion of the at least one cable is arranged along the second face and against the peripheral face, such that the at least one cable is at least partially offset in this third portion relative to the axis of rotation of the optical deflection element.

18. Light module according to claim 4 , wherein a flat is formed axially by machining the peripheral face, said at least one cable, being pressed against said flat.

19. Light module according to claim 7 wherein a support plate of the light source has a first face bearing the light source and a second face arranged against the first face of the first part of the support, said at least one cable being connected to a second face of the first support plate.

20. Light module according to claim 8 , wherein the light module comprises a guiding sleeve for the at least one cable fixed to the first part of the support.
