Abstract

PURPOSE: To ensure free and continuous change of transmitted light by arranging a lens plate faced to, and movable against, a light source and providing a color filter plate faced to the lens plate.
CONSTITUTION: A disc-shaped color filter plate 1 consists of regularly arranged small round color filters-- red filters R, blue filters B, and green filters G. A roughly disc-shaped lens plate 5 has plural small round lenses 6 made of glass, plastic or the like and arranged on the side faced to a light source, and has a planar opposite side face. Color change is effected by changing the relative position of the lens plate 5 and color filter plate 1 by parallel displacement of one or both of them.
