Abstract

Le module optique, utilisé à des fins d'éclairage et/ou de signalisation pour véhicule automobile, présente une optique primaire (11) pour former un premier faisceau lumineux (16, 17) à partir d'un rayonnement d'une source lumineuse (21), un ensemble pour dévier et diaphragmer le premier faisceau lumineux et une optique secondaire telle qu'une lentille pour former une face de sortie du module et mettre en forme un faisceau sortant. L'ensemble comprend un élément de cache (2) et une face réfléchissante (20) typiquement formée sur le dessus de cet élément (2) et permet de réaliser une coupure. La face réfléchissante (20) présente une première zone (Z1) déviant une partie du premier faisceau lumineux et une deuxième zone (Z2), adjacente à ou entourée par la première zone, ayant une propriété de surface qui rend cette zone (Z2) moins réfléchissante et/ou plus irrégulière, en raison d'une surcouche ou d'une excroissance formant une texture différente.
