Abstract

Une lentille de projection (13) est disposée de sorte que la lumière (L1, L2, L3, L4, L5) émise par une source de lumière (11) traverse la lentille de projection (13). Un masque (14) est disposé à l'arrière de la lentille de projection (13) de façon à bloquer une partie de la lumière (L1, L2, L3, L4, L5) émise par la source de lumière (11). La lentille de projection (13) comporte une première région (13a) et une seconde région (13b). La première région (13a) possède une première propriété de dispersion de la lumière. La seconde région (13b) possède une seconde propriété de dispersion de la lumière inférieure à la première propriété de dispersion de la lumière. Le masque (14) et la lentille de projection (13) sont disposés de sorte qu'une partie (L2) de la lumière (L2, L3) projetant un bord (14a) du masque (14) en tant que bord périphérique (50a) d'un motif de répartition de lumière (50) traverse la première région (13a) et une autre partie (L3) de la lumière (L2, L3) projetant le bord (14a) du masque (14) traverse la seconde région (13b).
