The LED power supply has the advantages that the energy conservation and high efficiency are realized, the environmental protection is rapidly developed in recent years, the plant lighting power supply in the important field of the LED power supply is developed and strengthened, the LED power supply works in a dimming turn-off mode or a standby working mode for a plurality of times, the power consumption of a plurality of products is up to several watts when the products are in standby, and a large amount of electric energy is wasted for a long time.
Disclosure of Invention
In order to solve the above problems, the present technical solution provides a circuit with low standby power consumption.
In order to achieve the purpose, the technical scheme is as follows:
a low standby power consumption circuit comprises an input end, a relay K1 and an output end;
the input end is connected with the output end through the relay K1;
the electrode end of the relay K1 is used for receiving a control signal to close the relay;
the control end of the relay K1 is connected with a main control unit U1 and is connected with a VCC end of the main control unit U1;
a PWM signal pin of the main control unit U1 is connected with an MOS (metal oxide semiconductor) tube Q1, one end of the MOS tube Q1 is grounded, and the other end of the MOS tube Q1 is connected with the output end through a diode D2;
