Abstract

A lighting device for a motor vehicle. The device comprises
a wall comprising at least one protuberance and at least one first light source situated inside the protuberance.

The wall comprises a reflecting zone having light reflection properties, and formed facing the first light source, such that the first light source is able to generate a light beam passing through the wall, that is propagated outside the lighting device before being reflected on the reflecting zone of the wall to generate an apparent lighting from the wall.

First claim

What is claimed is:

1. A lighting device for a motor vehicle (V), comprising:
a wall comprising at least one protuberance; and
at least one first light source situated inside said at least one protuberance;
said wall comprises a reflecting zone located outside said lighting device, said reflecting zone having light reflection properties, and formed facing said at least one first light source, such that said at least one first light source is able to generate a light beam passing through said wall, that is propagated outside said lighting device before being reflected on said reflecting zone of said wall to generate an apparent lighting from said wall;
wherein said wall delimits a space internal to said lighting device and a space external to said lighting device,
said lighting device further comprising:
at least one second light source situated in said internal space in said reflecting zone having light reflection properties;
wherein at least a part of said reflecting zone having light reflection properties also has light transmission properties such that a light beam generated by said second light source can pass through said wall in said part of said reflecting zone.

2. The lighting device according to claim 1 , wherein said reflecting zone has a reflection rate of at least 30%.

3. The lighting device according to claim 2 , wherein said at least one first light source and/or said at least one second light source comprises at least one light-emitting diode.

4. The lighting device according to claim 2 , wherein said wall is manufactured by injection molding.

5. The lighting device according to claim 2 , wherein said at least one protuberance comprises a first light output surface formed facing said reflecting zone for said light beam generated by said at least one first light source to be reflected on said reflecting zone.

6. The lighting device according to claim 5 , wherein said at least one protuberance further comprises a second light output surface formed for said light beam generated by said at least one first light source and/or an auxiliary light source situated in said at least one protuberance to be propagated directly toward the outside space without being reflected on said reflecting zone.

7. The lighting device according to claim 6 , wherein said first light output surface and/or said second light output surface comprises a material having light transmission properties.

8. The lighting device according to claim 1 , wherein said at least part of said reflecting zone also having said light transmission properties has a transmission rate of at least 30%.

9. The lighting device according to claim 8 , said at least one first light source and/or said at least one second light source comprises at least one light-emitting diode.

10. The lighting device according to claim 8 , wherein said wall is manufactured by injection molding.

11. The lighting device according to claim 1 , wherein said at least one first light source and/or said at least one second light source comprises at least one light-emitting diode.

12. The lighting device according to claim 1 , wherein said wall is manufactured by injection molding.

13. A signaling light for a motor vehicle, wherein it is formed by said lighting device according to claim 1 .

14. The signaling light according to claim 13 , situated on the rear face of said motor vehicle, said motor vehicle comprising a rear door,
wherein said rear door comprises a door reflecting zone having light reflection properties formed facing said at least one first light source and/or said at least one second light source, such that said at least one first light source and/or said at least one second light source is able to generate a light beam that is reflected on said reflecting zone of said rear door to generate an apparent lighting from said reflecting zone of said rear door.
