LED (Light Emitting Diode) lighting device

The invention provides an LED (Light Emitting Diode) lighting device. A mains supply input end, a surge filter circuit, a rectification circuit, a voltage reduction circuit and a constant-current integrated circuit which are connected in sequence; the mains supply input end is provided with a live wire end and a null line end; an anti-surge circuit is provided with at least three piezoresistors and at least four inductors; and the voltage reduction circuit is provided with at least two LED lamp beads connected in series. The inductors are matched with the piezoresistors to gradually absorb surge current to protect high surge, and the LED lamp beads are connected in series to reduce voltage, so that a design scheme formed by combining the two circuits solves the technical problems of low anti-surge capacity of an LED street lamp and dependency on an LED driver in the prior art and achieve technical effects of improving the anti-surge capacity of the lamp, being suitable for a more severe environment, eliminati
