Abstract

La présente invention concerne une structure de distribution de lumière immergée pour un véhicule automobile qui est utilisée pour configurer des faisceaux lumineux émis par des sources de lumière en faisceaux immergés. Au moins deux sources de lumière sont agencées dans un ordre séquentiel. La structure de distribution de lumière immergée pour un véhicule automobile comprend une première lentille interne (1) utilisée pour créer une limite de coupure clair/obscur d'un faisceau transmis, une seconde lentille interne (2) agencée au niveau d'une position aval d'un trajet de transmission de faisceau de la première lentille interne (1) et une lentille externe (3) agencée au niveau d'une position aval d'un trajet de transmission de faisceau de la seconde lentille interne (2). La structure de distribution de lumière immergée utilise une extrémité de sortie optique d'une lentille, à savoir une surface optique de la lentille, pour former une limite de coupure clair/obscur, de sorte qu'une plaque d'arrêt n'est pas requise, ce qui permet de surmonter l'inconvénient de l'utilisation d'une plaque d'arrêt, permettant à une structure de distribution de lumière d'être fabriquée dans diverses tailles, et répondant aux exigences de lampes de véhicule présentant différentes formes.
