Abstract

L’invention concerne un module lumineux (2) d’un dispositif d’éclairage (1) d’un véhicule automobile, comportant une source lumineuse (21) et un dispositif optique (22), le dispositif optique étant agencé pour recevoir de la lumière émise par la source lumineuse et pour former, à partir de cette lumière, un faisceau lumineux (F1, F3) présentant une coupure supérieure (LB1, LB3) comportant une première portion (LB11, LB31) et une deuxième portion (LB12, LB32) sensiblement horizontales et séparées par une troisième portion (LB13, LB33) descendant depuis la première portion et remontant vers la deuxième portion, ladite troisième portion étant telle que le faisceau lumineux présente, lorsqu’il est projeté sur un écran, une zone (W) dépourvue de lumière s’étendant au moins, horizontalement, dans une plage allant sensiblement de 0° à -2,2° et, verticalement, dans une plage allant sensiblement de 0° à -0,8°.
