According to one implementation of a spot illumination apparatus a spot luminaire includes a light source (117) for emitting a beam of light and a projection lens (170) configured to project the beam of light towards a distant target. A first field stop, through which the beam of light passes, is positioned between the light source and the projection lens. A filter apparatus (95) is positioned proximate the first field stop (125) and is adapted for selectively moving at least one variable density filter across the beam of light. A relay lens group (220) is positioned between the first field stop (125) and the projection lens (170). The relay lens group is configured to prevent the at least one variable density filter from being imaged by the projection lens.

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.
