Abstract

A room wall switch circuit with a light-operated LED night light comprises a switch, of which one end is connected with a live wire end of a 220v power supply, and the other end is connected to the zero line end of the 220v power supply via a large lighting lamp. First capacitors are parallelly connected to the two ends of the large lighting lamp. One end of the switch is connected to one end of a bridge type rectifier diode via a second capacitor, and the other end of the switch is connected with the other end of the bridge type rectifier diode. A third capacitor and a Zener diode are parallelly connected to one end of the bridge type rectifier diode. After one end of the third capacitor and one end of the Zener diode are parallelly connected to the bridge type rectifier diode, the other ends of the third capacitor and the Zener diode are grounded. The cathode of the Zener diode is connected with one end of a first resistor, and the other end of the first resistor is connected with a serial circuit formed by a first night light and a second night light. A photoresistor is connected to the anode of the first resistor, the other end of the photoresistor is connected to the base electrode of a triode, and the base electrode of the triode is grounded via a third resistor. The collector electrode of the triode is grounded, and the emitter electrode of the triode is connected with the cathode of the second night light.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a room wall switch circuit with a light-controlled LED night light. Background technique [0002] Wall switches and wall sockets are used a lot in household electricity. Household electricity is 220V power supply. Wall switches and sockets are installed on the wall. Switches are used to control the switches of various electrical appliances and lighting lamps. Powers when plugged in. The traditional wall switch has a single function and cannot meet actual needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a room wall switch circuit with a light-controlled LED night light, which is simple in structure, economical and environment-friendly. [0004] The technical problem to be solved by the present invention adopts the following technical solutions to realize: [0005] A room wall switch circuit with a light-contr...
