Abstract

Il est proposé un module lumineux pour véhicule automobile apte à être configuré pour exécuter une première fonction d'émission d'un faisceau lumineux à coupure, la coupure délimitant une zone éclairée et une zone sombre, et une deuxième fonction d'émission d'un faisceau lumineux sans coupure, la zone sombre étant alors éclairée. Le module lumineux comprend une première source lumineuse apte à être utilisée avec la première fonction et une deuxième source lumineuse apte à être utilisée avec la deuxième fonction. Il comprend également une plieuse agencée pour créer la coupure du faisceau lumineux à coupure lorsque la première fonction est exécutée. Il comprend aussi un élément optique apte à former le faisceau lumineux avec ou sans coupure, l'élément optique comprenant des dioptres, au moins un des dioptres comportant une ou plusieurs zones, chaque zone modifiant la trajectoire d'une partie de la lumière, émise par la deuxième source lumineuse, traversant l'élément optique.There is proposed a light module for a motor vehicle capable of being configured to perform a first function of emitting a cut-off light beam, the cut-off defining an illuminated zone and a dark zone, and a second function of emitting a light beam. light beam without cut-off, the dark area then being illuminated. The light module comprises a first light source suitable for use with the first function and a second light source suitable for use with the second function. It also comprises a folder arranged to create the cut-off of the cut-off light beam when the first function is performed. It also comprises an optical element capable of forming the light beam with or without cut-off, the optical element comprising diopters, at least one of the diopters comprising one or more zones, each zone modifying the trajectory of part of the light emitted. by the second light source, passing through the optical element.
