LIGHT GUIDE HAVING A STRIP MADE OF DIFFUSING MATERIAL

摘要

Lighting or signaling device, comprisinga light guide (3) comprising a transparent block, comprising an entrance surface (310) and a light exit surface (320),one or more light sources (2) located opposite the input surface (310) of the light. This device is of the type in which the rays emitted by the light source penetrate into the transparent block (3). ) at the input surface (310) of the light and propagate directly or by successive reflections on the walls of the transparent block in a general direction (D) common to the exit surface (320) through which they emerge. A strip (4) composed of a scattering material is arranged in a cross-section between the entrance surface (310) and the exit surface (320) of the light guide, so that the light rays pass through said strip ( 4) from the input surface (310) to the exit surface (320).
