Abstract
A hybrid power architecture for lighting system that physically separates the conversion of AC-DC constant voltage power from the conversion of DC-DC constant current needed to drive the LEDs. The hybrid power architecture comprises a power converter to generate DC volt power, a battery backup unit for providing backup in the event of power failure and control architecture for controlling the intensity of the lighting system.
