Abstract

Projecteur (1) de véhicule (2), configuré pour générer une zone d'éclairage (3) au devant du véhicule (2) et comprenant :- une première source (10) d'éclairage matriciel fixe configurée pour émettre un faisceau lumineux de route (11),- une seconde source (20) d'éclairage mobile configurée pour émettre un faisceau lumineux de croisement (12), et- un mécanisme de correction (30) configuré pour maintenir une inclinaison verticale constante du faisceau lumineux de croisement (12) par rapport à une ligne horizontale (H) de référence, lorsque le véhicule est en roulage,caractérisé en ce qu'il comprend en outre une lentille (40) dioptrique, présentant au moins une face d'incidence plane, configurée pour supprimer au moins une zone d'ombre (5) pouvant survenir, au niveau de ladite zone d'éclairage (3), entre le faisceau lumineux de route (11) et le faisceau lumineux de croisement (12). Figure à publier avec l’abrégé : Fig. 4Headlight (1) for a vehicle (2), configured to generate a lighting zone (3) in front of the vehicle (2) and comprising:- a first fixed matrix lighting source (10) configured to emit a main beam (11),- a second mobile lighting source (20) configured to emit a dipped beam (12), and- a correction mechanism (30) configured to maintain a constant vertical inclination of the dipped beam (12) relative to a horizontal reference line (H), when the vehicle is moving,characterized in that it further comprises a dioptric lens (40), having at least one flat incidence face, configured to eliminate at least one shadow zone (5) which may occur, at the level of said lighting zone (3), between the main beam (11) and the dipped beam (12). Figure to be published with the abstract: Fig. 4
