Abstract:
An adaptive power regulation converter for battery powered emergency lighting LED driver is disclosed. The power feedback and power compensation circuits regulate the output power to LED strings and provides tighten regulated constant power and constant lumens for emergency light during power out time. The adaptive power regulation converter can be used for a great range of LED strings.

Claim (Index 1):
A regulated power LED driver circuit comprising a first circuit electrically connected to a second circuit, the first circuit comprising an analog multiplier and being adapted to generate an output power sampling signal in the form of voltage signal from sampling of output current and sampling of output voltage and a voltage divider to scale down the output power sampling signal, the second circuit comprising a power feedback and power compensation network adapted to receive the scaled-down output power sampling signal from the first circuit, a comparator adapted to generate a power error signal by comparing the scaled-down output power sample signal with a reference voltage, a resistor adapted to provide a primary current feedback signal, a switcher, and a pulse width modulation (PWM) comparator adapted to receive as inputs the power error signal and the primary current feedback signal and to generate a modulated pulse width signal and thus control the switcher's turning on and off, to regulate the power of the LED driver circuit.
