1. A luminaire comprising:
a light engine control system comprising a power supply, a power delivery and measurement (PD&M) module, a light engine power control (LEPC) module, and a light engine, wherein:
the PD&M module and the LEPC module are configured to receive a first command that includes a desired light intensity of a light beam emitted by the light engine;
the PD&M module is configured to receive electrical power from the power supply and to control electrical power supplied to the LEPC module;
the LEPC module is configured to receive electrical power from the PD&M module and to control electrical power supplied to the light engine; and
the PD&M module is configured to:
repeatedly measure an electric power supplied to the light engine from the LEPC module; and
determine whether the measured electric power deviates by more than a threshold amount from an electric power that causes the light engine to emit light of the desired light intensity and, in response to such deviation, stop delivering power to the LEPC module; and
a light effect control system comprising a motor driver module, a position monitor module, and a mechanical and optical effect system, wherein:
the motor driver module and the position monitor module are configured to receive a second command that includes a desired configuration of the mechanical and optical effect system;
the motor driver module is configured to compare the desired configuration to a current configuration of the mechanical and optical effect system and, in the event of a mismatch, to reconfigure the mechanical and optical effect system into the desired configuration;
the position monitor module is configured to:
repeatedly measure a sensed position of one or more effect motors of the mechanical and optical effect system; and
determine whether the sensed position deviates by more than a threshold amount from the desired configuration and, in response to such deviation, cause a reduction in an intensity of the light beam emitted by the luminaire.
