Abstract

L'invention concerne un réflecteur fabriqué en un matériau transparent et qui comporte sur sa surface dorsale des prismes à réflexion totale qui réfléchissent la lumière pénétrant dans le corps dudit réflecteur. Ces prismes à reflexion totale sont des pentaprismes à 90 degrés dont le faîte 3 est orienté en direction de l'axe optique, et l'angle entre ce faîte par la perpendiculaire à la bissectrice de l'angle alpha formé par les rayons incidents et émergents se propageant dans le matériau réflecteur. Ce réflecteur est principalement destiné aux feux de position des véhicules automobiles.
