Abstract

L'invention concerne un système de guidage de la lumière comportant un filtre de couleur absorbant 3 placé entre la source lumineuse 1 et l'exrémité d'entrée de la lumière 4 du guide de lumière. Ce système est caractérisé en ce qu'on intercale un deuxième filtre de couleur 2 entre la source lumineuse et ce filtre de couleur. Il est utile notamment dans les dispositifs de signalisation pour la circulation.The invention relates to a light guide system comprising an absorbent color filter 3 placed between the light source 1 and the light inlet end 4 of the light guide. This system is characterized in that a second color filter 2 is inserted between the light source and this color filter. It is particularly useful in traffic signaling devices.
