A two-wire intelligent switch power-taking mechanism, connection device, adapter part and lamp

Abstract

The invention discloses a two-wire system intelligent switch power-taking mechanism. The two-wire system intelligent switch power-taking mechanism is characterized in that the input end of a voltage division unit is connected with an input live wire of the mains supply; the output end of the voltage division unit is connected with a lamp wire; the two input ends of a voltage transformation unit are connected with the input end and the output end of the voltage division unit respectively; the output end of the voltage transformation unit is connected with a control unit; the control unit is connected with a switch unit; the input end of the switch unit is connected with the input end of the voltage division unit; the output end of the switch unit is connected with the output end of the voltage division unit; the lamp part is provided with an electromagnetic switch and a piezoresistor; the electromagnetic switch is provided with a normally-open switch and a driving coil; the input end ofthe normally-open switch is connected with the output end of the voltage division unit; the output end of the normally-open switch is connected with the first power supply input end of the lamp; oneend of the piezoresistor is connected with the output end of the voltage division unit while the other end of the piezoresistor is connected with one end of a driving coil; and the other end of the driving coil is connected with a second power supply input end of the lamp. When the lamp is turned off, the lamp does not flicker, and power taking in a shunting manner through the lamp is not needed.

Description

technical field [0001] The invention relates to an intelligent switch power-taking circuit system, in particular to a two-wire intelligent switch power-taking mechanism and a connecting device thereof. Background technique [0002] With the advancement of science and technology, intelligent control is getting closer and closer to our production and life. Among them, switches in production sites and home lighting systems have also become intelligent, changing from mechanical switches to touch-type intelligent control switches, which can achieve more Multifunctional, but at the same time, the smart switch also needs a power supply to support its work. Since the backlight and indicator functions are generally required after the light is turned off, it consumes more power than when the light is turned on. In order to achieve continuous and stable power supply for the switch, the existing wiring is generally In the two-wire system, when the lights are turned off, the switching po...

[0002] With the advancement of science and technology, intelligent control is getting closer and closer to our production and life. Among them, switches in production sites and home lighting systems have also become intelligent, changing from mechanical switches to touch-type intelligent control switches, which can achieve more Multifunctional, but at the same time, the smart switch also needs a power supply to support its work. Since the backlight and indicator functions are generally required after the light is turned off, it consumes more electricity than when the light is turned on. In order to achieve continuous and stable power supply for the switch, the existing wiring is generally In the two-wire system, when the lights are turned off, the switching power supply is generally obtained by forming a circuit through the lamps. The lamps have currents passing through them, which causes the lights to flicker when they are turned off. Also, it is not easy to form a circuit with the emerging LED lamps, which still needs to be developed. solve
