Abstract

La présente invention concerne un guide de lumière (1) conçu pour être monté dans un véhicule, ledit guide de lumière comprenant : une portion de couplage présentant une face d'entrée,une portion principale adjacente à ladite portion de couplage,une surface de sortie de lumière s'étendant au moins le long de la portion principale, le guide de lumière étant disposé de telle sorte que les rayons lumineux qui entrent dans le guide de lumière par la face d'entrée se propagent par réflexion interne totale le long de la portion de couplage puis le long de la portion principale, avant de sortir du guide de lumière par la surface de sortie, dans lequel ladite face d'entrée de lumière est plate et a une périphérie qui est formée par seulement cinq bords de sensiblement la même taille, ces bords se rejoignant de telle sorte qu'ils forment cinq angles de sensiblement la même valeur. Figure pour l'abrégé : Fig. 3
