| Zusammenfassung: | The invention discloses an LED illumination control circuit capable of adjusting color temperature and brightness with memory, comprising a fuse F1, a capacitor CX1 and a rectifier bridge DB1. One endof a switch POWER is connected with a 220V AC live wire end, and the other end of the switch POWER is connected with the fuse F1. The other end of the fuse F1 is respectively connected to one end ofthe capacitor CX1, an inductor L2 and a resistor R1. The other end of the resistor R1 is connected to the other end of the inductor L2 and one input of the rectifier bridge DB1, respectively. The other input of the rectifier bridge DB1 is respectively connected to the resistor R2 and an inductor L3. The other end of the inductor L3 is respectively connected to the other end of the resistor R2, theother end of the capacitor CX1 and a 220V AC zero wire end. One output of the rectifier bridge DB1 is connected to a capacitor CE1, an inductor L1 and a resistor R7, respectively. The LED illumination control circuit adopts PI |
