Abstract

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.
