Safe energy-saving partial voltage electricity-borrowing switch

Abstract

The invention provides a safe and energy-saving voltage-dividing and electricity-borrowing switch, which is composed of a starting switch AN, a controlled switch K, a voltage-dividing and electricity-borrowing circuit RJ and a switch control circuit K; the voltage-dividing and electricity-borrowing circuit RJ and the controlled switch K are connected with a load RL in series; the voltage-dividing and electricity-borrowing circuit RJ is further connected with the switch control circuit K in parallel, thus ensuring the controlled switch K to get the electricity to be closed during the work of the load RL and lose the electricity to be cut off during the standby. The voltage-dividing and electricity-borrowing switch effectively solves the problems of standby energy conservation of the existing computer and television, at the same time, the voltage-dividing and electricity-borrowing switch provides the switch control (module) circuit for standby with a source, voltage division and electricity (power) borrowing which can replace the standby function of a main machine, so the voltage-dividing and electricity-borrowing switch can be taken as a reference for the development of the products which are more safe and energy-saving by combining with the requirements of the electrical technology of the products. The voltage-dividing and electricity-borrowing switch further has the advantages of simple circuit, low cost and so on.

Description

technical field [0001] The invention relates to an on / off circuit of electrical equipment, in particular to an energy-saving voltage-dividing and power-borrowing switch for household appliances such as computers, televisions, and voice-activated lighting. Background technique [0002] Existing computers, TVs and other household appliances all adopt non-power-off standby power-off circuits (not powered off, waiting for the next time to start up conveniently in a short period of time), and the standby power-off lights of voice-activated lighting (switch) lamp holders sold on the market Circuits (standby current above 700 microamperes, poor overload capacity, narrow application range of lighting types), the energy-saving effect is not very ideal, because the power consumption during standby is relatively large. The main reason is that in the power supply circuit of the existing electrical equipment, the standby shutdown circuit not only has many components and high cost, but al...
