Interior lighting device for a motor vehicle

1. An interior lighting device for a motor vehicle, the interior lighting device comprising:

at least one light source configured to emit at least one light beam;

at least one projection support;

a sensor configured to detect a condition outside the motor vehicle; and

processing circuitry configured to control the light source,

control the at least one projection support to be in a passive mode or in an active mode in which the light beam forms an image on said projection support, according to a manual or automatic driving mode of the motor vehicle, and

project the image based on the detected condition outside the motor vehicle.

2. The interior lighting device according to claim 1 , wherein the light source is a device for projecting light and/or static or dynamic images and/or videos.

3. The interior lighting device according to claim 2 , wherein the light source is a pico-projector.

4. The interior lighting device according to claim 1 , wherein the light source is installed in a front and/or a rear ceiling of the motor vehicle and/or in a center console and/or in at least one rear console.

5. The interior lighting device according to claim 1 , wherein the projection support is a glazed surface of the motor vehicle arranged to switch reversibly from a transparent state to an opaque state.

6. The interior lighting device according to claim 5 , wherein the glazed surface is a windshield and/or at least one front and/or rear side window and/or a sunroof and/or a rear window.

7. The interior lighting device according to claim 5 , wherein the glazed surface comprises an electrochromic glass.

8. The interior lighting device according to claim 7 , wherein the electrochromic glass has a composite structure.

9. The interior lighting device according to claim 7 , wherein the electrochromic glass is covered with an electrochromic film.

10. The interior lighting device according to claim 1 , wherein front and/or rear zones of the motor vehicle interior and/or the projection supports and/or the light sources are configured independently and autonomously.

11. The interior lighting device according to claim 1 , further comprising:

a memory configured to store static and/or dynamic image file, wherein

the processing circuitry is further configured to read the static and/or dynamic image files from the memory.

12. The interior lighting device according to claim 11 , further comprising a database of images prestored or transferred using a removable multimedia device.

13. The interior lighting device according to claim 12 , wherein the removable multimedia device is a digital data storage SD memory card or a USB key or a smartphone or a camera or a laptop PC or a tablet or a DVD player.

14. The interior lighting device according to claim 1 , further comprising at least one control button installed at a rear of the motor vehicle interior.

15. The interior lighting device according to claim 1 , wherein the sensor is a temperature sensor or a light intensity sensor.

16. A method for lighting at least a part of an interior space of a motor vehicle by an interior lighting device, said method comprising at least:

detecting, by a sensor, a condition outside the motor vehicle;

configuring at least one projection support of the motor vehicle by attenuation of light transmission;

configuring at least one light source of the interior space of the motor vehicle to direct a light beam from said at least one light source onto the configured projection support; and

projecting an image based on the detected condition outside the motor vehicle.

17. The method according to claim 16 , further comprising analyzing the data detected by the sensor, the sensor being a temperature sensor or a light intensity sensor.

18. The method according to claim 16 , further comprising selecting and reading image files prestored in a memory or transferred by at least one occupant of the motor vehicle using a removable multimedia device.

19. The interior lighting device according to claim 2 , wherein the light source is installed in a front and/or a rear ceiling of the motor vehicle and/or in a center console and/or in at least one rear console.

20. The interior lighting device according to claim 2 , wherein the projection support is a glazed surface of the motor vehicle arranged to switch reversibly from a transparent state to an opaque state.
