Abstract

Selon une mise en AEuvre d~un appareil d~éclairage par projecteur, un luminaire de projecteurs comprend une source lumineuse (117) pour émettre un faisceau de lumière et un objectif de projection (170) configuré pour projeter le faisceau de lumière vers une cible distante. Un premier arrêt de champ, à travers lequel le faisceau de lumière passe, est positionné entre la source lumineuse et l~objectif de projection. Un appareil de filtre (95) est positionné à proximité du premier arrêt de champ (125) et est adapté pour déplacer sélectivement au moins un filtre de densité variable sur le faisceau de lumière. Un groupe de lentilles de relais (220) est positionné entre le premier arrêt de champ (125) et l~objectif de projection (170). Le groupe de lentilles de relais est configuré pour empêcher l~au moins un filtre de densité variable d~être imagé par l~objectif de projection.
