Patent Number:	5186536
Title:	Lighting Instrument with Movable Filters and Associated Actuation Mechanism
Abstract:	A lighting instrument having pivotable color filters arranged in a substantially radial arrangement with respect to a projected light beam. Multiple sets of such filters are spaced along the axis of the light beam to vary the color of the light beam emitted from the instrument. A motorized mechanism rotates each filter of each set in synchronization with each other and independently with respect to filters of the other sets. The filters may be rotated by the motorized mechanism through flexible coupling mechanisms. The filters also may be positioned to pass unfiltered light to vary the saturation of the light beam.
