Abstract: A light effect system includes a light source and at least one aperture element interposed between the light source and an exit lens of the system. The aperture element has at least one aperture and at least one light effect element positioned therein. The system uses an aperture element having at least two “fingers” partly surrounding each light effect element in at least 180° of the circumference. These “fingers” engage with the contour of the outer surface of the light effect element to hold the light effect element in position in the aperture, and the fingers are formed of a flexible material. Hereby, it is achieved that the locking and releasing of the light effect component can be done by push and pull in an ideal perpendicular direction to the light path.
