Patent ID: 7482761

Claim:
A light emitting diode lamp assembly comprising: a light emitting diode (LED) string comprising multiple light emitting diodes (LEDs) connected in series; and a plug connected to the LED string and an external AC power source and having a circuit board mounted in the plug, turning the LED string on or off, converting AC power to DC power and comprising an AC/DC circuit connected to the external AC power source and the LED string and converting AC power to DC power to provide operating power for the LEDs; a control circuit connected to the AC/DC circuit to regulate illumination of the LEDs; and a switch circuit connected between the LED string and the AC/DC circuit, activated by the control circuit to turn the LEDs on or off and being a silicon controlled rectifier (SCR) having an anode terminal connected to the LED string; a cathode terminal connected to the AC/DC circuit; and a gate terminal connected to the control circuit.
