Original Abstract Submitted
A lighting device, including a first and a second ferroresonant transformer, is provided. Each ferroresonant transformer includes an input winding, an energy storage winding, and an output winding. Each input winding is configured to receive the same AC power. The input windings are arranged on the primary sides of the ferroresonant transformers. The energy storage windings and the output windings are arranged on the secondary side of the ferroresonant transformers. Each energy storage winding is electrically coupled to the same group of capacitors. The output windings are configured to provide output power signals based on the capacitors and the AC power. The output power signals have constant current and constant voltage. The output power signals are rectified, smoothed, and provided to one or more LEDs. Additional ferroresonant transformers may be added to the lighting device to accommodate requirements for increased power levels.
