Abstract
A safety-related signalling device for a motor vehicle including a light guide, a first light source capable of emitting a light beam that illuminates a lateral face of the light guide to allow the light beam to propagate in the light guide, and a reflective screen having a front face located at a distance and across from a rear face of the light guide. The light guide is translucent and light-coloured, and the reflective screen promotes diffuse reflection of the light from the light guide so as to homogenize and intensify, on a front face, the light emitted by the light guide.
Claims15
A signalling device for a motor vehicle, comprising a light guide delimited by a front face, substantially parallel to a rear face, lateral faces connecting the front face to the rear face, a first light source capable of emitting a light beam illuminating a lateral face of the light guide to allow the propagation of the light beam between the front face and the rear face of the light guide, a reflection screen including a front face arranged remote from and opposite the rear face of the light guide, wherein the light guide is translucent, and in that the front face of the reflection screen is light-coloured and favours a diffuse reflection of the light coming from the light guide, the front face of the reflection screen being preferably of white colour and matt appearance.
