Abstract

A light module, comprising: a support comprising at least one first surface called a separating surface and at least one organic light-emitting diode comprising a first light-emitting part, a connecting part or means for attaching the diode to the support and an electrical connector or means for electrically connecting the diode. The means for attaching the diode and the electrical connector or means for electrically connecting the diode are borne by a part of this diode, called a connecting part. Additionally, the separating surface of the support delimits a light-scattering area into which the first light-emitting part of the diode extends, and separates this light-scattering area from a masked area, into which connecting part of the diode extends, such that the connecting part is occulted by the separating surface of the support.

Claims

1. A light module, comprising:

a support comprising a separating surface; and

at least one organic light-emitting diode including

a first light-emitting part,

a connecting part attaching said organic light-emitting diode to said support, and

an electrical connector electrically connecting said organic light-emitting diode,

wherein said connecting part attaching said organic light-emitting diode and said electrical connector electrically connecting said organic light-emitting diode are both borne by the connecting part of said organic light-emitting diode,

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, and

wherein 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.

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.
