Lighting or signalling device with optical guide for motor vehicles

摘要

A lighting and/or signalling device for a motor vehicle comprising at least one light source (S) emitting a light beam and at least one optical guide (G) within which the light beam propagates, the optical guide comprising:
a first face forming an exit face (FS) for the light beam,a second face forming a face (FR) for reflecting the light beam, anda screen (ED) disposed facing the reflection face (FR) of the light guide (G) and comprising an orientation means redirecting light rays escaping from the guide at the reflection face, so as to return them, at least partially, into the guide, the orientation means comprising catadioptric reflecting patterns.
