Patent ID: 8026671

Claim:
An LED assembly and a power supply circuit thereof for supplying current from a power source to the LED assembly, comprising: a plurality of LEDs, a groove being formed on a top face of one of the pair of electrode leads, a tab projecting outwardly from a distal end of the other one of the pair of electrode leads, the plurality of LEDs being so connected together that the groove of each LED fittingly accommodating the tab of an adjacent LED therein; an AC circuit for connecting with the power source a DC circuit connected to the AC circuit; a driving circuit connected between the LEDs and the DC circuit; and a snubber circuit connected to the driving circuit, wherein the current provided by the power source is received by the AC circuit, and is then converted to a DC by the DC circuit, and wherein after passing through the snubber circuit, the DC is provided to the LEDs, wherein the snubber circuit flattens a curve of a voltage value of the DC in respect to time initially supplied to the LEDs, thereby to protect the LEDs from a damage caused by a sharp rise of the voltage value of the DC initially supplied to the LEDs.
