Abstract

A light device for a motor vehicle lighting and/or signaling device includes a flexible surface light source a housing arranged to conform at least a part of the flexible surface light source according to a predetermined form a cap arranged to press said part of the flexible surface light source against the housing the housing and/or the cap being capable of allowing light emitted by the flexible surface light source to pass.

First claim

The invention claimed is:

1. A light device for a motor vehicle lighting and/or signaling device comprising:
a flexible surface light source;
a housing arranged to conform at least a part of the flexible surface light source according to a predetermined form; and
a cap arranged to press said part of the flexible surface light source against the housing, wherein the housing and/or the cap being configured to allow light emitted by the flexible surface light source to pass,
wherein the housing includes a peripheral flange extending from a bottom wall of the housing and defining an enclosure for receiving the flexible surface light source, and
wherein the cap includes a peripheral flange configured to interlock with the peripheral flange of the housing.

2. The light device according to claim 1 , wherein the device comprises a hinge linking the cap and the housing arranged so that the cap is mobile with respect to the housing to allow the insertion of the flexible surface light source between the housing and the cap.

3. The light device according to claim 1 , wherein the housing and the cap are two distinct elements.

4. The light device according to claim 3 , wherein the housing and the cap are arranged to come into contact so as to encapsulate the flexible surface light source.

5. The light device according to claim 4 , wherein the flexible surface light source rests on the bottom wall of the housing and in that the flexible surface light source is pressed by a pressing wall of the cap onto the bottom wall of the housing.

6. The light device according to claim 5 , wherein at least a part of the cap rests on said peripheral flange of the housing to encapsulate the enclosure.

7. The light device according to claim 6 , wherein at least a part of the cap, defining the pressing wall of the cap, is inserted into the enclosure to press the flexible surface light source against the bottom wall of the housing.

8. The light device according to claim 5 , wherein at least a part of the cap, defining the pressing wall of the cap, is inserted into the enclosure to press the flexible surface light source against the bottom wall of the housing.

9. The light device according to claim 5 , wherein at least the pressing wall of the cap is produced in a transparent or translucent material.

10. The light device according to claim 5 , wherein at least the pressing wall of the cap is produced in a material configured to color the light emitted by the flexible surface light source.

11. The light device according to claim 5 , wherein at least a part of the pressing wall of the cap is arranged to deflect at least a part of the light emitted by the flexible surface source to produce a predetermined photometric function.

12. The light device according to claim 1 , wherein the flexible surface light source is an organic light-emitting diode.

13. The light device according to claim 1 , further comprising locking means configured to cooperate with complementary locking means of the flexible surface light source to eliminate the play of said flexible surface light source in the housing.

14. The light device according to claim 1 , the housing is arranged to conform at least the part of the flexible surface light source according to the predetermined form without resin.
