Patent ID: 8525425

Claim:
An LED lighting system, comprising: an LED circuit including: a first LED having an anode and a cathode; a second LED having an anode and a cathode, the anode of the second LED being electrically coupled to the cathode of the first LED, the cathode of the second LED being electrically coupled to the anode of the first LED, the first and second LEDs being in an inverse-parallel arrangement, the first LED acting as a reverse-voltage clamp for the second LED, and the second LED acting as a reverse-voltage clamp for the first LED; and a triac having a first triac anode, a second triac anode and a gate, the first triac anode being electrically coupled to the cathode of the first LED and the second triac anode being electrically coupled to the anode of the first LED; and a transient voltage suppressor having a first suppressor anode and a second suppressor anode, the first suppressor anode being electrically coupled to the first triac anode and the second suppressor anode being electrically coupled to the gate of the triac, the triac being latched to a conducting state in the event the first LED fails in an open electrical circuit while in a conducting state, and the triac being latched to a conducting state in the event the second LED fails in an open electrical circuit while in a conducting state.
