Abstract

The invention deals with a support for light source(s) for a light module, notably for a motor vehicle, comprising a substrate; at least one surface light source of the organic light-emitting diode type supported by the substrate, the at least one surface light source comprising, at one or more edges, at least two electrical contact zones; electrical tracks deposited on the substrate; and electrical contacts between the electrical contact zones of the light source or sources and the electrical tracks. The electrical contacts comprise elastic blades, in contact under pressure with the contact zone or zones of the surface light source or sources and with the electrical tracks on the substrate.

First claim

What is claimed is:

1. A support for light source(s) for a light module for a motor vehicle, comprising:
a part;
a substrate;
at least one surface light source, said at least one surface light source being an organic light-emitting diode mounted on said part, said at least one surface light source comprising at least two electrical contact zones;
electrical tracks deposited on said substrate; and
electrical contacts between said electrical tracks and said at least two electrical contact zones of said at least one surface light source;
wherein said electrical contacts comprise elastic blades in contact under pressure with said at least two electrical contact zones of said at least one surface light source and with said electrical tracks.

2. The support according to claim 1 , wherein said at least two electrical contact zones of said at least one surface light source in electrical contact with said electrical track forms an angle with said at least two electrical contact zones of said electrical track in contact with said elastic blade, said angle being greater than 30°.

3. The support according to claim 1 , wherein each of said elastic blades comprises at least two bent portions, each of said at least two bent portions being in contact with one of said electrical contact zones of said at least one surface light source or with one of said electrical tracks.

4. The support according to claim 1 , wherein each of said elastic blades comprises, on at least one of its ends, a generally planar portion suitable for sliding along a guiding surface.

5. The support according to claim 1 , wherein said part comprises an added part supporting said elastic blades.

6. The support according to claim 4 , wherein an added part comprises said guiding surfaces for planar end portions of said elastic blades.

7. The support according to claim 6 , wherein said added part comprises guiding grooves forming said guiding surfaces and receiving said planar end portions of said elastic blades.

8. The support according to claim 5 , wherein said added part comprises at least one edge supporting said elastic blades.

9. The support according to claim 8 , wherein said added part comprises two edges supporting said elastic blades, said edges extending essentially parallel to one another, said added part comprising a main groove between said edges, said main groove receiving the edge of an extended portion of said substrate.

10. The support according to claim 9 , wherein said elastic blades comprise first elastic blades each overlapping exclusively one of said two edges.

11. The support according to claim 10 , wherein said first elastic blades have a generally U-shaped profile and ensure an electrical contact between said electrical tracks and said at least two electrical contact zones of said at least one surface light source.

12. The support according to claim 10 , wherein said elastic blades comprise second elastic blades, each of said second elastic blades overlapping said two edges and extending through said main groove of said added part.

13. The support according to claim 12 , wherein said second elastic blades have a profile comprising two generally U-shaped lateral portions each overlapping one of said two edges and a generally U-shaped central portion, opposite said two generally U-shaped lateral portions.

14. The support according to claim 12 , wherein said second elastic blades ensure an electrical contact between said at least two electrical contact zones of said at least one surface light source arranged on either side of said extended portion of said substrate.

15. The support according to claim 5 , wherein an edge of an extended portion of said substrate forms a protruding tongue, said electrical tracks on said substrate extending to said tongue, said added part comprising a notch or an opening suitable for receiving said tongue so as to form a space for said tongue to engage with an electrical connector.

16. A light module for a motor vehicle, comprising a support for light source(s) and at least one optical device, wherein said support conforms to claim 1 .

17. The support according to claim 2 , wherein each of said elastic blades comprises at least two bent portions, each of said at least two bent portions being in contact with one of said electrical contact zones of said at least one surface light source or with one of said electrical tracks.

18. The support according to claim 2 , wherein each of said elastic blades comprises, on at least one of its ends, a generally planar portion suitable for sliding along a guiding surface.

19. The support according to claim 3 , wherein each of said elastic blades comprises, on at least one of its ends, a generally planar portion suitable for sliding along a guiding surface.

20. The support according to claim 5 , wherein said added part comprises the guiding surfaces for planar end portions of said elastic blades.
