Claim:
1. An emergency lighting module for providing emergency power to a solid state luminaire, the emergency lighting module comprising: 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, wherein the microcontroller is configured to output a first dimming control signal to the solid state luminaire in response to the status signal, wherein the first dimming control signal is configured to control operation of a dimming controller in the solid state luminaire, and wherein the microcontroller is further configured to output a select signal to the solid state luminaire to enable the luminaire to select from between the first dimming control signal and a second dimming control signal that is input to the solid state luminaire and to cause the solid state luminaire to dim a light emitting diode (LED) of the solid state luminaire in accordance with the first dimming control signal when the first dimming control signal is selected.
