Intelligent dimming LED (Light Emitting Diode) lighting system

An intelligent dimming LED (Light Emitting Diode) lighting system comprises the mains supply input end, a control device and an LED light source allowing color change. The control device comprises the mains supply rectifier filter input end, a flyback type switch unit, a light dimming and color adjustment driving unit, a microcomputer controller, a switch signal detection unit, a mobile phone bluetooth control unit, a wireless remote control unit, an electric memory, a current detection unit and a current control unit. According to the intelligent dimming LED lighting system, switch signals are detected through mains zero passage signals, memory users switch the light color or brightness which is set by the lighting system through the electric memory, and accordingly the color adjustment and the brightness adjustment of the lighting system can be compatible to the same lamp, relevant data cannot be lost due to the restart, and the remote control can be performed through a mobile phone, a remote control and the like.
