Abstract

A lighting module for a motor vehicle including at least one light source designed to emit light rays, optical deviation elements mounted movably in rotation about a first axis of rotation and arranged so as to deviate the light rays to form a light beam, and an actuator designed to rotate the optical element. According to the invention, the module is also designed to be movable in rotation about a second of rotation.

Claims

1. Lighting module for a motor vehicle including at least:

one light source designed to emit light rays,

optical deviation elements mounted movably in rotation about a first axis of rotation and arranged so as to deviate said light rays to form a light beam,

an actuator designed to rotate the optical element, said module also being designed to be movable in rotation about a second axis of rotation.

2. Lighting module according to claim 1, wherein the first and second axes of rotation are substantially perpendicular to one another.

3. Lighting module according to claim 1, wherein a support carries the light source.

4. Lighting module according to claim 3, including elements for guiding the optical deviation elements in rotation about the first axis of rotation, said rotational guide elements being arranged between the optical deviation elements and the support.

5. Lighting module according to claim 1, wherein the actuator includes an output shaft extending along the first axis of rotation and carrying the optical deviation elements.

6. Lighting module according to claim 5, wherein the output shaft and the rotational guide elements are arranged on either side of the optical deviation elements along the first axis of rotation.

7. Lighting module according to claim 1, wherein the optical deviation elements comprise a substantially elliptical reflector, the light source being arranged substantially in the vicinity of a first focus of said reflector.

8. Lighting module according to claim 3, wherein said second axis of rotation is formed at least partially by an element carried by the support.

9. Lighting module according to claim 8, wherein the second axis of rotation is defined at least partially by two projections projecting from the support, designed to cooperate with bearings.

10. Lighting module according to claim 1, wherein the lighting module is associated with its own connecting rod, which is rigidly connected firstly to the actuator and, at a second opposite extremity, to a support carrying the light source and overlapping the optical deviation elements of the related lighting module.

11. Lighting module according to claim 10, wherein the lighting module is rotated about the second axis of rotation by an actuation element designed to push the connecting rod.

12. Lighting module according to claim 11, wherein the actuation element is designed to push on a first end of the connecting rod opposite the end of the connecting rod that is rigidly connected to the support containing the second axis of rotation.

13. Lighting module according to claim 11, wherein the actuation element includes a board carrying attachment means that are designed to cooperate with attachment means carried on the connecting rod.

14. Lighting device, notably for lighting and/or signaling in a motor vehicle, including at least one lighting module according to claim 1.

15. Lighting device according to claim 14, wherein the lighting module includes a housing and a closing outer lens delimiting a seat for the at least one lighting module.

16. Lighting device according to claim 15, wherein the at least one lighting module is associated with at least one plate rigidly connected to the housing and carrying bearings used to define the second axis of rotation.

17. Lighting device according to claim 16, wherein the lighting module includes an assembly of at least two of said lighting modules, each being involved in forming a light beam, the aggregation of the primary light beams forming a global light beam at the output of the device.

18. Lighting device according to claim 17, wherein said second axis of rotation is specific to each lighting module.

19. Lighting device according to claim 14 wherein the lighting module includes an assembly of at least two of said lighting modules each being involved in forming a light beam, the aggregation of the primary light beams forming a global light beam at the output of the device.

20. Lighting device according to claim 14, wherein said second axis of rotation is specific to each lighting module.
