Abstract: A highly compact, light weight automated luminaire is disclosed having a head unit mounted on a support structure which provides pan and tilt of the head unit. The latter includes beam controlling optics providing precise control over beam parameters including color. Groups of the instruments are remotely controlled from a digital controller such as a PC connected by cable or a wireless link to the instruments. The lights each include processors for processing comands from the digital controller. By reason of its light weight and compactness, the luminaire is suitable for many applications barred to conventional automated lighting fixtures.

Abstract: A nonplanar mechanical dimmer for use in a variable parameter luminaire includes claws, a mounting region and a convex beam blocking region which does not reflect energy back onto a light source during dimming.
