Abstract

Une lampe pour véhicule (10) comporte une lentille de projection (12) qui est disposée sur un axe optique qui s'étend dans la direction longitudinale du véhicule, une DEL (14) qui émet de la lumière qui est dirigée vers le foyer arrière (F) de la lentille de projection (12), une DEL (16) qui émet de la lumière qui est dirigée vers le foyer arrière (F) de la lentille de projection (12), et un masque (22) qui peut non seulement former un motif de répartition de lumière comportant une première ligne de découpe en découpant une partie de la lumière émise par la DEL (14) mais également former un second motif de répartition de lumière comportant une seconde ligne de découpe en découpant une partie de la lumière émise par la DEL (16). Le masque (22) est disposé de sorte que son bord avant (22a) est positionné plus en arrière que le foyer arrière (F).
