Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: a switch color-changing LED circuit with a memory function comprises an LED light source working circuit, wherein the LED light source working circuit is connected with a main stream output control circuit, the main stream output control circuit is connected with an output circuit adjusting circuit, the output circuit adjusting circuit is connected with the LED light source working circuit, the main stream output control circuit is connected with a filter circuit, the filter circuit is connected with a rectifying circuit, the filter circuit is connected with a switch conversion memory control circuit, the switch conversion memory control circuit is connected with a power supply circuit, the power supply circuit is respectively connected with the filter circuit and the main stream output control circuit, the LED light source working circuit is respectively connected with the switch conversion memory control circuit through a color temperature control 1 line and a color temperature control 2 line, and the switch conversion memory control circuit is connected with a level detection control circuit;

the LED light source working circuit comprises an LQ5412 chip, a plurality of VCC pins are arranged on the LQ5412 chip, the VCC pins are connected with an output anode through a power supply resistor, and the current of the VCC is more than 0.5 mA;

the low-voltage power supply circuit is characterized in that a detection pin is arranged on the LQ5412 chip, the detection pin is a CLK pin, the CLK pin is connected with L or N of the AC through a detection resistor, delay time Td (on) (typical value 67mS) for judging the switch closing state and delay time Td (off) (typical value 30mS) for judging the switch opening state are designed in the LQ5412 chip, and the LQ5412 detects AC input voltage through the CLK pin to judge the on-off state. The CLK pin may also detect high and low signals. In order to filter noise and avoid false triggering, delay time Td (on) (typical value 67mS) for judging the switch closing state and delay time Td (off) (typical value 30mS) for judging the switch opening state are designed in the LQ 5412;

two 400V thyristors are arranged in the LQ5412 chip, and the conduction saturation voltage is about 1.4V (IDx is 250 mA);
