Abstract

L'invention concerne un module (22) optique destiné à projeter un faisceau (24) lumineux final présentant un profil de coupure (28) présentant au moins un tronçon (28A, 28C) horizontal, et comportant : - une source (34) lumineuse commandée émettant un faisceau (46) initial ; - des moyens (36) optiques de coupure pour transformer le faisceau (46) initial en un faisceau (48) intermédiaire à coupure (28) dans lequel les rayons lumineux sont distribués verticalement au-dessous dudit profil de coupure (28) ; caractérisé en ce que le module (22) optique comporte : - des moyens (38) optiques de focalisation horizontale pour focaliser le faisceau (48) intermédiaire à coupure vers une ligne (54) de focalisation sensiblement verticale ; - une lentille (40) de sortie présentant une ligne (54) focale verticale qui est confondue avec la ligne (54) de focalisation pour transformer le faisceau (48) intermédiaire à coupure en ledit faisceau (24) final.
