Driving circuit of 220V AC LED lamp

The invention discloses a driving circuit of a 220V AC LED lamp, which belongs to the application of electronic technology in the lighting field. The invention relates to a driving circuit of a 220V AC LED lamp.

The AC side of the rectifier circuit is composed of series inductance coil step-down current limiting circuit; the DC side is parallel rectifier circuit with a filter circuit composed of capacitors, composed of Zener diode voltage limiting protection circuit and LED array. Rectifier circuit consists of diode rectifier bridge.

The LED array can be made up of multiple LED, and the LED array can also be connected in series by multiple LED. The invention has the advantages of simple circuit, high reliability, low cost, no need for debugging, good manufacturability and high efficiency energy saving; inductance with step-down current limiting function, reliable and durable; after rectifying and filtering to drive the LED array, LED can avoid the flicker luminous intensity, stability and soft.
