Abstract
A device for manipulating any lighting fixture's light beam by means of a servo motor (82), linkage (80), a universal joint (90), and a reflecting means (76). The main plate (54) can be positioned along the rods (38) to intercept the focal point of the lighting fixture's light beam. The frame plate (36) can be interchanged with other size frame plates to allow different size lighting fixtures to use the same manipulation device. The invention can be controlled by any lighting console or computer with a accessable control signal. The unit can be controlled by either a wired or wireless signal.
