CA 2267321

The device comprises at least one tubular wall (31) of a material able to filter colour from the light, and arranged, when set in its active position, to laterally embrace the projector light source (10) so as to be traversed by the light before this reaches the reflector means (20); said tubular wall (31) can be moved from said active position to an inactive position in which it does not interfere with the radiation emitted by the source (10) and directed towards the reflector means (20), and vice versa.

Le dispositif selon l'invention comprend au moins une paroi tubulaire (31) constituée en un matériau permettant de filtrer la couleur de la lumière. En outre, cette paroi est disposée de telle sorte, qu'une fois placée en position opérationnelle, elle enveloppe latéralement la source (10) de lumière du dispositif de projection et est traversée par la lumière avant que celle-ci n'atteigne le moyen (20) formant réflecteur. Cette paroi tubulaire (31) peut être déplacée pour passer de la position opérationnelle à une position inactive dans laquelle elle n'interfère pas avec le rayonnement émis par la source (10) et orienté vers le moyen formant réflecteur (20), et vice et versa.
