Abstract

L'invention concerne un module optique destiné à des projecteurs, en particulier de véhicules ferroviaires, pour générer une répartition lumineuse définie avec une limite clair-obscur, lequel module optique se caractérise par une résistance aux secousses particulièrement bonne. Pour cela, le module optique présente une source lumineuse, une optique primaire servant à collimater la lumière venant de la source lumineuse, un diaphragme servant à supprimer une partie de la lumière collimatée par l'optique primaire et une optique secondaire servant à projeter la lumière collimatée par l'optique primaire et non supprimée par le diaphragme. L'optique primaire comprend un guide de lumière (14) basé sur le principe de la réflexion interne totale, comprenant une surface d'entrée de lumière (40) et une surface de sortie de lumière, cette dernière comprenant au moins deux parties de surface (24, 44) rayonnant dans des directions différentes. Le guide de lumière (14) présente au moins deux éléments d'appui (26), qui sont formés d'un seul tenant avec lui et qui servent à fixer le guide de lumière (14) par rapport à la source lumineuse de manière résistante aux secousses.
