Abstract

Un feu de véhicule comprend une lentille de projection (12), des première et deuxième plaquettes d'émission de lumière (14a1, 14a2) disposées sur des côtés gauche et droit, et un réflecteur (16) qui réfléchit de la lumière vers la lentille de projection (12). Le réflecteur (16) comprend une surface réfléchissante (16a). Une zone arrière gauche (16a1R) et une zone avant droite (16a2F) de la surface réfléchissante (16a) réfléchissent de la lumière émise par la première plaquette (14a1) pour converger vers un point focal arrière de la lentille de projection (12) à un degré de convergence plus élevé que de la lumière émise par la deuxième plaquette (14a2). Une zone arrière droite (16a2R) et une zone avant gauche (16a1F) de la surface réfléchissante (16a) réfléchissent de la lumière émise par la deuxième plaquette (14a2) pour converger vers le point focal arrière de la lentille de projection (12) à un degré de convergence plus élevé que de la lumière émise par la première plaquette (14a1).
