Abstract

La présente invention concerne un projecteur d'affichage séquentiel en couleur pouvant projeter une image claire dont la balance des blancs est améliorée et qui prolonge la durée de vie d'un dispositif d'éclairage. Dans le but de simplifier un circuit permettant de contrôler la commande du dispositif d'éclairage, le projecteur d'affichage séquentiel en couleur comprend une source de lumière, un moyen d'extraction de lumière colorée à répartition dans le temps comprenant une roue de couleurs divisée en segments colorés, un moyen de modulation de lumière pour la formation d'une image d'affichage séquentiel en couleur et un moyen de projection pour agrandir et projeter l'image d'affichage séquentiel en couleur. Les segments colorés (6a à 6f) sont chacun disposés de façon à former un angle central prédéterminé par rapport au centre de rotation d'une roue de couleurs (6). L'angle central d'une région de couleurs (1) composée de deux segments colorés adjacents (6a, 6b) ou plus est égal à l'angle central d'une région de couleurs (2) composée d'un autre segment coloré (6d) ou de deux autres segments colorés adjacents ou plus. Pendant que la région de couleurs (1) et la région de couleurs (2) traversent un trajet optique de lumière qui est entrée dans la roue de couleurs (6), le flux lumineux émis à partir de la source de lumière est accru.
