Abstract

L'invention concerne une unité d'éclairage, destinée à un phare de véhicule automobile pour générer un faisceau de lumière comportant une limite clair-obscur, comportant : - au moins une source de lumière (1, 1a, 1b), - un réflecteur (2), - une lentille de sortie (3) ayant une surface extérieure (3a), - une zone d'axe focale (4) disposée entre le réflecteur (2) et la lentille de sortie (3) et en outre un collimateur (10, 10a, 10b) pour chaque source de lumière (1, 1a, 1b). Le collimateur (10, 10a, 10b) dirige les rayons lumineux alimentés (S1), injectés dans le collimateur (10, 10a, 10b) par la source de lumière (1, 1a, 1b) qui lui est associée, pour former un faisceau de rayons lumineux (S2). Le réflecteur dévie les rayons lumineux du faisceau de lumière sortant du collimateur jusque dans un axe focal se trouvant dans la zone d'axe focal. Les rayons lumineux réfléchis par le réflecteur sont déviés par la lentille de sortie au moins dans une direction verticale de telle sorte que les rayons lumineux sortant de la lentille de sortie forment une distribution de lumière comportant une limite clair-obscur. La surface extérieure (3a) de la lentille de sortie (3) est formée par une structure en forme de rainures réalisée dans une surface de base lisse (BF). Les rainures (3b) formant la structure en forme de rainures s'étendent dans une direction sensiblement verticale et, de préférence, deux rainures (3b), adjacentes dans la direction horizontale, sont séparées par une élévation qui s'étend en particulier sensiblement verticalement et qui s'étend de préférence sur toute l'extension verticale des rainures (3b).
