Abstract

L'invention a pour objet la réalisation d'un guide d'onde optique qui a un éclairage optimal pour une structure simple. A cet effet, les surfaces réfléchissantes (13, 14) sont décalées entre elles transversalement à la direction de rayonnement de l'élément lumineux (8, 11) et sont rattachées les unes aux autres, vues dans la direction de rayonnement, pratiquement sans interstice. Ainsi, aucune formation d'ombre ne se produit entre les surfaces réfléchissantes (13, 14) de sorte que la lumière émise par l'élément lumineux (8, 11) est utilisée de façon optimale. Le guide d'onde optique est utilisé pour les systèmes d'éclairage de véhicules automobiles.
