Abstract
An emergency lighting module for providing emergency power to a solid state luminaire includes a microcontroller, and a detector coupled to the microcontroller and configured to detect a status signal indicative of a status of an AC line voltage, the emergency lighting module is configured to output a dimming control signal to the solid state luminaire in response to a reduction of the AC line voltage. The microcontroller is further configured to output a select signal to the solid state luminaire to cause the solid state luminaire to dim in accordance with the dimming control signal when the dimming control signal is output.
