Abstract
An emergency lighting module for providing emergency power to a solid state luminaire is provided. The emergency lighting module includes a control circuit configured to detect a line voltage, a first input configured to receive an input voltage from the solid state luminaire, and a bidirectional booster/charger circuit coupled to the microcontroller and configured to charge a battery using the input voltage. The bidirectional booster/charger circuit is further configured to provide an output voltage. The emergency lighting module is configured to provide the output voltage to the solid state luminaire in response to a reduction of the line voltage.
