Patent ID: 8610358

Claim:
A lighting system, comprising: at least one light emitting diode; a power supply coupled to the at least one light emitting diode and operable to convert a received power signal into a feedback-regulated power signal that is provided to the at least one light emitting diode, the power supply, including: a rectifier; a transformer coupled to the rectifier and having a primary winding and a secondary winding; a switch operable to at least partially control current passing through the primary winding; an overvoltage protection device coupled between an output of the rectifier and the primary winding; and an overcurrent protection device coupled between the switch and a common voltage reference that is common to the rectifier and the primary winding,the overcurrent protection device being operable to conduct an induced current from a ground reference node to the primary winding of the transformer; and a feedback circuit coupled between the at least one light emitting diode and the switch and operable to vary a magnitude of the feedback-regulated power signal.
