OPTICAL SYSTEM WITH MAIN FUNCTION FOR MOTOR VEHICLE
First Claim
1. An optical system for a motor vehicle, said optical system performing at least one main optical function and including in particular:
- a diffusion screen;
at least one light source, notably of the LED type, each light source of the optical system producing a set of rays of light to be propagated in the diffusion screen;
wherein the screen is in the form of a sheet, notably curved or substantially planar, with an upper lateral flange and a lower lateral flange which are joined by means of a periphery having a rear face and a front edge;
the main function is performed essentially via an output face constituted by the front edge of the diffusion screen; and
least one part of the upper lateral flange diffuses a light beam contributing notably to the performance of the main function and/or performing a complementary optical function.

Abstract
An optical system for a motor vehicle, the optical system performing at least one main optical function and including in particular
a diffusion screen,
at least one light source of the LED type, each LED of the optical system producing a set of rays of light to be propagated in the diffusion screen
wherein the screen is in the form of a curved sheet, with an upper lateral flange and a lower lateral flange which meet at a periphery which has in particular a rear face and a front edge
and the principal function is performed essentially via an output face constituted by the front edge of the diffusion screen.
