Abstract

La présente invention concerne généralement un système optique pour projecteur à effet aquatique et spécifiquement un système d’angle de faisceau variable élargissant la plage d’angles de faisceau et augmentant l’intensité lumineuse. La présente invention contient un élément optique modulateur de lumière présentant une ouverture centrale susceptible de se déplacer le long de l’axe optique du système. De plus l’ouverture centrale de l’élément modulateur peut être obstruée par un élément diffuseur. On peut également jouer sur le degré d’obstruction. Dans une première position limite dans laquelle le système optique est réglé sur une divergence minimale de faisceau, le faisceau lumineux va traverser l'ouverture sans perte d’intensité. Dans cette configuration le premier élément optique n’a pratiquement aucun effet sur le faisceau. Dans une seconde position limite dans laquelle le système optique est réglé sur une divergence maximale de faisceau, les diffuseurs recouvrent l’ouverture centrale pour diffuser l’éclairage central et ainsi éviter toute intensité excessive au centre du faisceau. Une ouverture de taille variable permet également d’étendre la plage d’angles de faisceau et de modulation de lumière.
