Abstract

Projecteur lumineux pour véhicule automobile, comprenant un réflecteur (R) de type ellipsoïdal ou multi-ellipsoidal, deux sources lumineuses, un moyen optique (A) situé devant le réflecteur et un cache situé entre les sources lumineuses et le moyen optique,le réflecteur comportant deux parties séparées par un plan méridien virtuel passant sensiblement au voisinage d'au moins l'une des sources lumineuses, les deux parties du réflecteur admettant des foyers différents, une première partie du réflecteur étant située d'un premier côté du plan et étant affectée à une première fonction, et une deuxième partie du réflecteur située de l'autre côté du plan méridien étant affectée à la deuxième fonction :- la première partie (R1) de réflecteur forme une image (Fg; Fh) de la première source lumineuse (L1,b1;b1m) située du premier côté du plan méridien (P,Pm), sur le cache ou au voisinage,- la deuxième partie (R2) du réflecteur forme une image (Fd ; Fb) de la deuxième source lumineuse (L2,b2 ;b2m) située de l'autre côté du plan méridien (P,Pm), et- le moyen optique (A) comprend une première (1,1m) et une deuxième (2,2m) portions de lentille situées de part et d'autre du plan méridien
