Abstract
A variable light modifier provides rapid beam deflection and flipping with a minimum of noise, power consumption and heat generation. In one embodiment of the invention, a dual-sided reflector is pivotable along orthogonal axes by pan and tilt mechanisms. The pan and tilt mechanisms are driven by pan and tilt motors, one or both of which remain stationary with respect to the yoke. The variable light modifier can be used to deflect light beams generated by one or more light sources and can reflect the light from one or both reflective surfaces of the reflector.
