Abstract
L'invention a pour objet un projecteur de lumière. Une source 14 émet rayons L1, L2, L3 qui sont renvoyés par un réflecteur R5 devant lequel est monté déplaçable un élément T de transmission qui présente des zones de diffusion 40, 42 donnant un rayonnement diffus, et des zones de non diffusion, donnant un faisceau de rayons parallèles, selon sa position. L'invention est applicable notamment aux projecteurs de scène qui doivent donner des faisceaux plus ou moins concentrés ou diversement colorés.
