Abstract

A motor vehicle directional lighting and/or signaling device comprises a light module rotationally mobile about an axis (A-A) supported by a base bearing elements for guiding in rotation about the axis (A-A). A bearing of the rotation guiding elements is formed partly by the base and partly by a support piece of a fan.

First claim

The invention claimed is:

1. Motor vehicle directional lighting and/or signaling device comprising at least:
one light module rotationally mobile about an axis (A-A);
elements for guiding this light module in rotation about the axis (A-A);
a base bearing at least some of the rotation guiding elements;
a fan;

wherein a bearing of the rotation guiding elements is formed partly by the base and partly by a support piece of the fan.

2. Directional lighting and/or signaling device according to claim 1 , wherein the guiding bearing is formed by a portion of circular profile arranged on a wall of the base and by a portion of circular profile arranged on a wall of the support piece arranged facing the base.

3. Directional lighting and/or signaling device according to claim 2 , wherein the guiding bearing is formed by two portions of equivalent profiles, arranged in mirror configuration.

4. Directional lighting and/or signaling device according to claim 1 , wherein the support piece is fixed to the base by fixing members arranged on either side of the guiding bearing.

5. Directional lighting and/or signaling device according to claim 1 , wherein the base and the support piece are formed in one and the same material.

6. Directional lighting and/or signaling device according to claim 1 , wherein the support piece has an open part for receiving an end of the fan.

7. Directional lighting and/or signaling device according to claim 6 , wherein the open part of the support piece is formed opposite the part forming the guiding bearing.

8. Directional lighting and/or signaling device according to claim 1 , wherein the support piece has at least fixing elements for the fan.

9. Directional lighting and/or signaling device according to claim 8 , wherein the fixing elements for the fan comprise at least one pair of retaining lugs extending opposite the part of the support piece forming the guiding bearing.

10. Directional lighting and/or signaling device according to claim 9 , wherein fixing elements for the fan are arranged laterally in the support piece whereas a positioning member is arranged in a central position relative to the support piece.

11. Directional lighting and/or signaling device according to claim 1 , wherein the light module comprises at least light ray emitting devices and cooling members.

12. Directional lighting and/or signaling device according to claim 11 , wherein the fan is situated directly above at least a part of the cooling members, relative to the direction of the axis of rotation (A-A).

13. Directional lighting and/or signaling device according to claim 1 , wherein the device comprises a casing defining, with a closing outer lens, a housing for at least one rotationally mobile light module.

14. Directional lighting and/or signaling device according to claim 13 , wherein the base is fixed to the casing.

15. Directional lighting and/or signaling device according to claim 3 , wherein the support piece is fixed to the base by fixing members arranged on either side of the guiding bearing.

16. Directional lighting and/or signaling device according to claim 4 , wherein the base and the support piece are formed in one and the same material.

17. Directional lighting and/or signaling device according to claim 5 , wherein the support piece has an open part for receiving an end of the fan.

18. Directional lighting and/or signaling device according to claim 17 , wherein the open part of the support piece is formed opposite the part forming the guiding bearing.

19. Directional lighting and/or signaling device according to claim 7 , wherein the support piece has at least fixing elements for the fan.

20. Directional lighting and/or signaling device according to claim 19 , wherein the fixing elements for the fan comprise at least one pair of retaining lugs extending opposite the part of the support piece forming the guiding bearing.
