Abstract

L’invention propose un dispositif de guidage de rayons lumineux et un module lumineux pour un véhicule automobile faisant recours à un tel dispositif. Le dispositif est remarquable en ce qu’il permet d’émettre des rayons lumineux couplés, possiblement issus d’une source lumineuse unique, dans une pluralité de directions de sorties distinctes le long de l’étendue du dispositif. Il en résulte par exemple la possibilité de réaliser des contours lumineux complexes impliquant une pluralité de lignes lumineuses, moyennant une source lumineuse unique et un guide de lumière unique. (Fig. 1)
