Abstract
The invention proposes a lighting module for motor vehicles, which comprises optical means for deviating in angular manner at least a portion of the light rays passing through them, without thereby changing the geometry of the projection lens of the lighting module.
Claims16
Lighting module for a motor vehicle, the module comprising:
- a first light source configured to produce a first lighting function of the motor vehicle, and
- a projection lens disposed downstream of the first light source,
- wherein the module comprises a screen provided with diffraction patterns, the screen being disposed between the focal plane of the lens and the projection lens, such that when the first light source emits light rays at least a first portion of the light rays coming from the first light source pass through the screen to produce a second lighting function deviated upwardly in a direction from a direction of the first lighting function, and a second portion of the light rays coming from the first light source do not pass through the screen to produce the first lighting function.
