Abstract

Une unité optique comprend un réflecteur rotatif (42) qui tourne dans une direction autour de son axe de rotation (R) tout en réfléchissant de la lumière émise à partir d'une source de lumière (28). Le réflecteur rotatif (42) est pourvu d'une pluralité de surfaces réfléchissantes (42a, 42b) de telle sorte que de la lumière de la source de lumière (28) réfléchie par le réflecteur rotatif (42) qui tourne est configurée pour former une configuration de distribution de lumière souhaitée (PH). Chacune des surfaces réfléchissantes comprend une première surface réfléchissante (42a) configurée pour former une première zone partielle (R1) de la configuration de distribution de lumière, et une deuxième surface réfléchissante (42b) configurée pour former une deuxième zone partielle (R2) de la configuration de distribution de lumière différente de la première zone partielle (R1).
