Abstract

L’invention concerne un dispositif d’éclairage (30), comportant des modules lumineux (30.1, 30.2) disposés adjacents dans une direction transversale (Y) du dispositif (30), chaque module (30.1, 30.2) comprenant une source lumineuse (30.10, 30.20) émettant un faisceau lumineux et un collecteur (30.11, 30.21) comportant une surface réfléchissante ; une lentille commune (31) aux modules (30.1, 30.2), agencée pour projeter le faisceau lumineux réfléchi par le collecteur (30.11, 30.21), ladite lentille (31) forme sur la route une image de la surface réfléchissante du collecteur (30.11, 30.21) . Selon l’invention, le dispositif d’éclairage (30) comporte une pluralité de circuits imprimés, chaque circuit imprimé supportant au moins la source (30.10, 30.20) d’au moins l’un des modules (30.1, 30.2); les circuits imprimés sont agencés dans le dispositif (30) de façon étagée dans des plans parallèles entre eux et la lentille commune (31) s’étendant dans une direction transversale (Y) en étant sensiblement inclinée par rapport à ces plans.
