The utility model relates to an intelligent control LED lighting circuit, which is composed of a high-voltage DC power source, an intelligent control switch module and a loop that is obtained by connecting the LED circuit units serially. The intelligent control LED lighting circuit adopts the serial connection of the intelligent control switch in the high-voltage lighting loop and breaks through aconventional thinking that the LED is only suitable for the intelligent control switch after pressure reduction in operation so that the intelligent control switch is free of high-voltage impulse. The technical problems of stability and interference resistance of the intelligent control circuit are effectively settled. Furthermore the standby power consumption of the intelligent control circuit can be ingeniously used for realizing the intelligent control of two-stage brightness of the LED lighting device.
