Abstract
A system for identifying a fault in a light source is presented. The system includes at least one luminaire that includes the light source configured to emit light. Also, the at least one luminaire includes a monitoring device disposed proximate to the light source. The monitoring device includes a sensing unit configured to measure an amount of light emitted by the light source, and a squawk unit configured to generate a squawk signal based on the amount of light emitted from the light source, where the squawk signal is indicative of the fault in the light source. Further, the system includes a diagnostic unit communicatively coupled to the at least one luminaire and configured to determine the fault in the light source based on the squawk signal, and transmit a termination signal to the squawk unit to decouple an electrical power supply from the light source.
