Abstract: The invention relates to a lighting and/or signaling device including an electroluminescent diode and a lightguide adapted to convey the light from the diode and also means for securing the diode relative to an end of the lightguide to ensure the position of an inlet face of the guide opposite the diode. The lightguide carries male securing means adapted to interact with female securing means carried by a plastics component carrying the electroluminescent diode. The plastics component further includes electric circuits produced directly on the plastics of this component in immediate proximity to the diode.

Abstract: 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, and a 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.
