Abstract

Dispositif de projection de motifs mobiles de lumière dispersée par au moins un réseau monté sur un plateau mobile, éclairé par au moins une source de lumière polychromatique. Chaque réseau donne un ensemble de spectres tournant autour de la direction de réflexion normale donnée par chaque projecteur. L'invention s'applique à la décoration lumineuse.Device for projecting mobile patterns of light dispersed by at least one network mounted on a mobile plate, illuminated by at least one polychromatic light source. Each grating gives a set of spectra revolving around the normal direction of reflection given by each projector. The invention applies to light decoration.
