Abstract
An automated lighting instrument according to the present invention includes multiple motorized parameters and operates at a low noise level with improved thermal management devices such as a reflector coated with a cold mirror film, a metallic heat sink, a housing with ventilating holes, and thermally isolating motor mounts. The improved thermal management devices provide the basis for an improved method for managing the thermal characteristics of the automated lighting instrument of the present invention.
