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.

First claim

The invention claimed is:

1. A lighting module for a motor vehicle comprising:
a 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, the optical deviation elements including a reflector with a reflective face, a lower end of the optical deviation elements connected to an output shaft and an upper end of the optical deviation elements including rotational guide elements;
a support which carries the light source and a portion of the rotational guide elements for the optical deviation elements about the first axis of rotation, the support including a circular upper face, a lower face, and a peripheral face connecting the upper and lower faces; and
an actuator designed to rotate the output shaft so as to rotate the optical deviation elements about the first axis of rotation,
wherein said module is movable in rotation about a second axis of rotation which is substantially perpendicular to the first axis of rotation,
wherein the second axis of rotation is defined at least partially by two projections projecting from the peripheral face of the support, the two projections designed to cooperate with bearings,
wherein the light source is substantially aligned with the first axis of rotation, and
wherein the first axis of rotation passes through the support, the optical deviation elements, and the actuator.

2. The lighting module according to claim 1 , wherein the reflector is substantially elliptical, the light source being arranged substantially in a vicinity of a first focus of said reflector.

3. The lighting module according to claim 1 , wherein the lighting module is associated with a connecting rod, which is rigidly connected at a first end to the actuator and at a second end to the support carrying the light source and overlapping the optical deviation elements.

4. The lighting module according to claim 3 , wherein the lighting module is rotated about the second axis of rotation by an actuation element designed to push the connecting rod.

5. The lighting module according to claim 4 , wherein the actuation element is designed to push on the first end of the connecting rod.

6. The lighting module according to claim 4 , wherein the actuation element includes a board carrying attachment means that are designed to cooperate with attachment means carried on the connecting rod.

7. A lighting device including at least one lighting module according to claim 1 .

8. The lighting device according to claim 7 , wherein the lighting module includes a housing and a closing outer lens delimiting a seat for the at least one lighting module.

9. The lighting device according to claim 8 , 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.

10. The lighting device according to claim 9 , wherein the lighting module includes an assembly of at least two of said lighting modules, each being involved in forming a primary light beam, an aggregation of the primary light beams forming a global light beam at an output of the device.

11. The lighting device according to claim 10 , wherein said second axis of rotation is specific to each lighting module.

12. The lighting device according to claim 7 , wherein the lighting module includes an assembly of at least two of said lighting modules each being involved in forming a primary light beam, an aggregation of the primary light beams forming a global light beam at an output of the device.

13. The lighting device according to claim 7 , wherein said second axis of rotation is specific to each lighting module.

14. The lighting module according to claim 1 , wherein the first axis of rotation extends in a vertical direction.
