An emergency LED lighting system maintains power to an LED lighting source based on measured voltages and currents provided to the LED lighting source; rolls back or decreases power provided to an LED lighting source over time in order to increase the amount of time the battery can power the LED lighting source; executes a soft start procedure, such that the power provided to the LED lighting source is gradually ramped up during activation of the LED lighting sources; identifies a type of battery coupled to the emergency LED lighting system; cycles the emergency LED lighting system between charging mode and standby mode to reduce power consumption over a window of time; detects AC power or an absence of AC power; and/or uses a status LED to communicate information about the emergency LED lighting system with a remote device.

Emergency lighting system with battery identification

Battery charge function may be in an LED driver which eliminates the duplication of line interface circuitry. A single line interface circuit provides the input power conversion for both the battery charge function and normal operation of the LED driver. During a loss of power, the LEDs may be controlled using power from the battery backup module.
