Light device comprising surface light sources

1. A light device, notably for lighting and/or signaling, for a motor vehicle, suitable for emitting at least one first light beam and one second light beam, the light device comprising a first surface light source and a second surface light source, in which:

said first surface light source is suitable for emitting first light rays (F 1 ) toward said second surface light source, said second surface light source being arranged so that said first light rays pass through said second surface light source to participate in said at least one first light beam, and

said second surface light source is suitable for emitting second light rays (F 2 ), said second light rays (F 2 ) participating in said second light beam

wherein said first surface light source is at least one of totally reflecting or semi-reflecting so that it reflects said second light rays (F 2 ) emitted by said second surface light source;

wherein each of said first surface light source and said second surface light source is curved, and

wherein said second surface light source comprises a generally spot light source associated with said second surface light source having a light output surface, a surface of emission of said second surface light source being formed by said light output surface of a light guide.

2. The light device as claimed in claim 1 , in which said second surface light source is suitable for emitting said second light rays (F 2 ) toward said first surface light source, said first surface light source being arranged so as to reflect said second light rays toward said second surface light source and said second surface light source being arranged so that said second light rays pass through it to participate in said second light beam.

3. The device as claimed in claim 2 , in which said second surface light source is transparent or translucent or semi-reflecting.

4. The light device as claimed in claim 2 , in which said first surface light source is an organic light-emitting diode.

5. The device as claimed in claim 1 , in which said second surface light source is transparent or translucent or semi-reflecting.

6. The light device as claimed in claim 1 , in which said first surface light source is an organic light-emitting diode.

7. The device as claimed in claim 1 , in which said first surface light source and said second surface each have a generally cylindrical form.

8. The light device as claimed in claim 1 , said light device being suitable for emitting a third light beam, in which said light device comprises a third light source suitable for emitting third light rays (F 3 ), said third light rays participating in said third light beam.

9. The light device as claimed in claim 8 , in which said third light source is an organic light-emitting diode.

10. The light device as claimed in claim 8 , in which said third light source is arranged behind said first surface light source and is suitable for emitting said third light rays (F 3 ) toward said first surface light source so that said third light rays pass successively through said first surface light source and said second surface light source to participate in said third light beam.

11. The light device as claimed in claim 10 , in which said third light source is an organic light-emitting diode.

12. The light device as claimed in claim 8 , in which said third light source is arranged in front of said second surface light source and is suitable for emitting said third light rays (F 3 ) toward said second surface light source so that said third rays pass through said second surface light source, are reflected by said first surface light source and pass successively through said first surface light source and said second surface light source to participate in said third light beam.
