BELEUCHTUNGS- ODER SIGNALVORRICHTUNG FÜR KRAFTFAHRZEUGE

摘要

The tip has a cavity (4) inside which a small size light source (1) e.g. light emitting diode, is placed partially. The cavity has a wall (8) crossed by light rays, and a ceiling surface (8b). A light rays receiving surface (7) totally reflects the light rays inside an optical guide (2). The surfaces (7, 8b) of the cavity have a corrugated profile permitting reflection and/or refraction of light rays with a high divergence angle in a manner so that the light rays spread inside the optical guide. Independent claims are also included for the following: (1) an optical guide for lighting or signaling a device for a vehicle comprising a tip (2) a lighting and a signaling device for a motor vehicle comprising an optical guide.
