Abstract

A light module, comprising:

• • a support (10) comprising at least one first surface called separating surface (101),
  • at least one organic light-emitting diode (20) comprising a first light-emitting part (200), means for attaching the diode to the support and means for electrically connecting the diode.

The means for attaching the diode and the means for electrically connecting the diode are borne by a part of this diode, called connecting part (210). Additionally, the separating surface (101) of the support delimits a light-scattering area into which the first light-emitting part (200) of the diode extends, and separates this light-scattering area from a masked area, into which connecting part (210) of the diode extends, such that said connecting part is occulted by the separating surface (101) of the support (10).

Claims

1. A light module, comprising:

a support comprising at least one first surface called separating surface; and

at least one organic light-emitting diode comprising a first light-emitting part, a connecting part or means for attaching said organic light-emitting diode to said support and an electrical connector or means for electrically connecting said organic light-emitting diode,

wherein said connecting part or means for attaching said organic light-emitting diode and said electrical connector or means for electrically connecting said organic light-emitting diode are borne by a part of said organic light-emitting diode, called said connecting part, wherein said separating surface of said support delimits a light-scattering area into which said first light-emitting part of said organic light-emitting diode extends, and separates said light-scattering area from a masked area, into which said connecting part of said organic light-emitting diode extends, such that said connecting part is occulted by said separating surface of said support.

2. The light module as claimed in claim 1, in which said organic light-emitting diode comprises a second light-emitting part separate from said first light-emitting part, said first light-emitting part and said second light-emitting part being separated from one another by said connecting part, and said support comprising two opposite separating surfaces, such that said connecting part is placed between each of said separating surfaces.

3. The light module as claimed claim 1, in which said support comprises a wall supporting said separating surface, said wall comprising at least one slot passing all the way therethrough, such that said connecting part of said organic light-emitting diode passes through said wall and comes out on a technical surface of said support, said technical surface being opposite said separating surface.

4. The light module as claimed in claim 3, in which a centering border, comprising an inner surface placed on the periphery of said at least one slot, is positioned on said technical surface of said support.

5. The light module as claimed in claim 4, in which the angle (a) formed by said inner surface of said centering border with said technical surface determines the gradient of said light-emitting part with respect to said separating surface of said support.

6. The light module as claimed in claim 4, in which said support comprises, on said technical surface side, fastening means capable of being directly connected to said support and to said connecting part of said organic light-emitting diode.

7. The light module as claimed in claim 6, in which said fastening means comprise a releasable locking element, resting on an upper support edge of said connecting part of said organic light-emitting diode.

8. The light module as claimed in claim 7, in which said releasable locking element comprises support ribs intended to rest on said upper support edge of said connecting part of said organic light-emitting diode.

9. The light module as claimed in claim 7, in which said locking element comprises an articulation connected to said technical surface of said wall of said support, or connected to said centering border.

10. The light module as claimed in claim 7, in which said locking element comprises a first fastening element intended to be connected by clipping together with a second fastening element positioned on said technical surface of said support, or positioned on said centering border.

11. The light module as claimed in claim 3, in which said connecting part of said organic light-emitting diode is mechanically connected to said support by means of an intermediate fastening module.

12. The light module as claimed in claim 11, in which said intermediate fastening module comprises means for connecting to said technical surface of said wall of said support.

13. The light module as claimed in claim 11, in which said intermediate fastening module comprises means for electrically linking with said electrical connection means of said organic light-emitting diode.

14. The light module as claimed in claim 11, in which said intermediate fastening module comprises two retaining clips, said two retaining clips being connected together by clamping means, such that said organic light-emitting diode is held in place by the pressure exerted by said two retaining clips on opposite support surfaces of said connecting part.

15. A lighting and/or signaling housing intended to be mounted on an automotive vehicle comprising at least one light module as claimed in claim 1.

16. The light module as claimed claim 2, in which said support comprises a wall supporting said separating surface, said wall comprising at least one slot passing all the way therethrough, such that said connecting part of said organic light-emitting diode passes through said wall and comes out on a technical surface of said support, said technical surface being opposite said separating surface.

17. The light module as claimed in claim 3, in which said support comprises, on said technical surface side, fastening means capable of being directly connected to said support and to said connecting part of said organic light-emitting diode.

18. A light module, comprising:

a support comprising at least one first surface called separating surface; and

at least one organic light-emitting diode comprising a first light-emitting part, a connecting part or means for attaching said organic light-emitting diode to said support and an electrical connector or means for electrically connecting said organic light-emitting diode,

wherein said connecting part or means for attaching said organic light-emitting diode and said electrical connector or means for electrically connecting said organic light-emitting diode are borne by a part of said organic light-emitting diode, called said connecting part, wherein said separating surface of said support delimits a light-scattering area into which said first light-emitting part of said organic light-emitting diode extends, and separates said light-scattering area from a masked area, into which said connecting part of said organic light-emitting diode extends, such that said connecting part is occulted by said separating surface of said support.

19. The light module as claimed in claim 18, in which said organic light-emitting diode comprises a second light-emitting part separate from said first light-emitting part, said first light-emitting part and said second light-emitting part being separated from one another by said connecting part, and said support comprising two opposite separating surfaces, such that said connecting part is placed between each of said separating surfaces.

20. The light module as claimed claim 18, in which said support comprises a wall supporting said separating surface, said wall comprising at least one slot passing all the way therethrough, such that said connecting part of said organic light-emitting diode passes through said wall and comes out on a technical surface of said support, said technical surface being opposite said separating surface.
