Abstract

Bloc optique pour projecteur de véhicule automobile, comportant un boitier fermé par une lentille optique (3), ledit boitier comportant une première rangée de réflecteurs paraboliques (40) et une deuxième rangée de réflecteurs parabolique (50) ; ledit bloc optique comportant en outre un réflecteur parabolique supplémentaire (60) implanté au voisinage de la jonction entre la première (40) et la deuxième (50) rangées de réflecteurs paraboliques et conformé pour être apte à réfléchir des rayons lumineux (R3) émis par au moins une source lumineuse supplémentaire pour réaliser une fonction d’éclairage complémentaire SBL des fonctions d’éclairage Flat et Spot de feux de croisement, dans les virages ; l’implantation du réflecteur parabolique supplémentaire (60) permettant de rendre invisible la non activation de la fonction d’éclairage complémentaire SBL, vu de l’extérieur du véhicule, quand les fonctions d’éclairage Flat et Spot de feux de croisement sont activées. (Figure 3)Optical unit for motor vehicle headlamp, comprising a housing closed by an optical lens (3), said housing comprising a first row of parabolic reflectors (40) and a second row of parabolic reflectors (50); said optical unit further comprising an additional parabolic reflector (60) located near the junction between the first (40) and the second (50) rows of parabolic reflectors and shaped to be capable of reflecting light rays (R3) emitted by at least one additional light source to realize an additional lighting function SBL of the Flat and Spot lighting functions of dipped beam, in bends; the installation of the additional parabolic reflector (60) to make the non-activation of the SBL additional lighting function invisible, seen from outside the vehicle, when the Flat and Spot dipped beam lighting functions are activated.
