Abstract
A luminaire includes a light engine control system and a light effect control system. The light engine control system includes a power delivery and measurement (PD&M) module, a light engine power control (LEPC) module, and a light engine. The light effect control system includes a motor driver module, a position monitor module, and a mechanical and optical effect system. The PD&M module measures electric power supplied to the light engine, determines whether the measured power deviates from a desired electric power and, in response, stops delivering power to the LEPC module. The position monitor module measures a sensed position of one or more effect motors of the mechanical and optical effect system, determines whether the sensed position deviates from the desired configuration, and in response, causes a reduction in an intensity of the light beam emitted by the luminaire.
