Embodiment Construction

[0013] Please refer to figure 1 A preferred embodiment of the energy-saving circuit of the present invention includes a power supply circuit 10 , a switch trigger circuit 20 and a detection trigger circuit 30 .

[0014] The power supply circuit 10 includes a relay J, one contact of the relay J is connected to a first power terminal V1, and the other contact is connected to a power output terminal OUT. The power output terminal OUT provides power for the system of the audio / video equipment. A second power terminal V2 is respectively connected to one end of the coil of the relay J and the cathode of a diode D3, and the other end of the coil of the relay J and the anode of the diode D3 are both connected to the collector of a transistor Q3. The emitter of the triode Q3 is grounded, the base of the triode Q3 is connected to one end of a resistor R10, and the other end of the resistor R10 is used as a control input end of the power supply circuit 10 to connect to the switch trigge...

Abstract

The invention discloses an energy saving circuit, which comprises a power supply circuit, a switch trigger circuit and a detection trigger circuit, wherein the power supply circuit comprises a first power end, a power output end and a control input end, the control input end receives a high level trigger signal and then enables the first power end to be conducted with the power output end, the power output end provides power for an audio / video equipment system, and after the switch trigger circuit is triggered, a high level signal is sent to the control input end; the detection trigger circuit comprises a signal unit, an amplifying unit and a first diode, the signal unit sends the audio / video signal to the amplifying unit, when the signal unit stops sending the audio / video signal, the amplifying unit outputs a low level signal, the first diode is cutoff, and the power supply circuit stops proving power for the audio / video equipment system. Due to the energy saving circuit, the audio / video equipment can be automatically shutdown when the audio / video equipment stops outputting the audio / video signal.

Description

technical field [0001] The invention relates to an energy-saving circuit. Background technique [0002] Users often forget to turn off the power when using various audio / video equipment.
