Abstract

Dispositif de projection d’images à changement d’image optimisé Un tel dispositif de projection d’images comprenant : au moins une LED émettant un faisceau lumineux d’éclairage, ainsi qu’un module de changement d’image comprenant différentes images à projeter montées sur disque couplé à un moteur pas à pas. Le dispositif comprend un circuit électrique de commande configuré pour commander le moteur de manière à faire tourner le disque pour changer l’image projetée, en commandant le moteur avec une fréquence de commande (f) de changement de pas qui : pendant une phase principale (Pp), est supérieure ou égale à une fréquence cible (fc) donnée, puis pendant une phase de décélération contrôlée (Pd), décroit progressivement jusqu’à zéro. Figure à publier avec l’abrégé : Figure 7
