Abstract
A lighting system for a motor vehicle includes a printed circuit board equipped with light-emitting diodes for producing light and an optical module to propagate and transmit the light. The optical module includes a reception surface to receive the light produced and an emission surface for retransmitting the light produced. The optical module includes a housing for receiving the printed circuit board equipped with light-emitting diodes and the housing includes an internal wall forming the reception surface.
Claims12
A lighting system for a motor vehicle, comprising:
- a headlight having a light source;
- a printed circuit board equipped with light-emitting diodes to produce light;
- and
- an optical module to propagate and transmit said produced light, said optical module including a solid body that has a reception surface to receive directly said produced light, and an emission surface to retransmit said directly received light to outside the optical module, the solid body defining a solid volume between the reception surface and the emission surface,
- wherein said optical module forms a housing that receives said printed circuit board equipped with said light-emitting diodes,
- wherein said housing includes an internal wall forming said reception surface of said optical module,
- wherein lateral internal end walls of said housing directly contact the printed circuit board equipped with said light-emitting diodes,
- wherein said reception surface and/or said emission surface has at least one portion configured to diffuse a first fraction of said directly received light and/or the solid volume of the solid body between a portion of the reception surface and a portion of the emission surface is configured to diffuse the first fraction of said directly received light,
- wherein said reception surface has at least one other portion configured to make converge a second fraction of said directly received light, which is different from the first fraction of said directly received light,
- wherein the headlight is external to the optical module that forms the housing,
- wherein the optical module forms a ring in a front view of the lighting system, and
- wherein the optical module in the form of the ring surrounds the headlight in the front view of the lighting system.
