Problems solved by technology

Therefore, the existing smart switches on the market, when there is no ground wire in the wall switch, have clear requirements on the power of the connected load lamps, that is, the current flowing through the load lamps in the off state cannot be greater than the load lamps to flicker or lighten On the other hand, the existing smart wall switch control methods are not rich enough, and users cannot choose conveniently and quickly according to different needs.

Embodiment 1

[0029] like figure 1As shown, a wall switch circuit for anti-flash single-fire power supply includes a main switch 1 arranged between the live wire L and the lamp wire L1 and connected to control the power on and off of the load. The impedance unit 3 for controlling the impedance, the power taking unit 4 for power taking and output power supply, the main switch control unit 2 for controlling the power on and off of the main switch 1, and the power taking unit 4 are connected in series. The main control unit 6 supplies power, and the main control unit 6 instructs the input terminal 6a to drive the impedance control unit 5 to control the impedance unit 3 to reduce the impedance after receiving the work instruction, so as to increase the flow current of the main switch control unit 2 and control the main switch 1 to turn on.

[0030] like figure 1 As shown, the 3a terminal of the impedance unit 3 is connected to the fire wire L and the 1a terminal of the main switch 1, the 3b te...

Embodiment 2

[0035] like figure 2 As shown, the impedance unit 3 and the power-taking unit 4 connected in series are connected in parallel with a compensation unit 7 for compensating the reactive current of the impedance unit 3.

[0036] like figure 2 As shown, the difference between the second embodiment of the circuit principle of the present invention and the first embodiment is that a compensation unit 7 is added, the 7a end of the compensation unit 7 is connected to the 3a end of the impedance unit 3, and the 7b end is connected to the 4b end of the power-taking unit 4, and the impedance The series circuit composed of the unit 3 and the power-taking unit 4 is connected in parallel to compensate the reactive current of the impedance unit 3. When the circuit resonates, the current flowing into the main switch control unit 2 and the load is greatly reduced compared with the implementation 1, thereby further preventing flicker and Slightly bright.

[0037] In order to explain the func...

Embodiment 3

[0055] like Figure 8 As shown, there is a manual switch K1 between the main switch 1, the electrical connection end of the impedance unit 3 and the live wire L, and a manual switch K2 is connected between the live wire L and the light wire L1; the command input terminal 6a of the main control unit 6 is connected with a sensing unit 8. Remote control unit 9 or remote control unit 10 .

[0056] like Figure 8 As shown, the difference between Embodiment 3 and Embodiment 2 of the circuit principle block diagram of the present invention is that a manual switch K1 is provided between the live wire L and the lamp wire L1, and the connection point between the live wire L and the manual switch K1 is connected to the 1a end of the main switch 1 and A manual switch K2 is provided between the connection points of terminal 7a of the compensation unit 7 . When you want to manually close the wall switch, you only need to manually close the manual switch K1. When you need to intelligently ...

Abstract

The invention discloses an anti-flash single-live-wire power-taking wall switch circuit, which comprises a main switch connected between a live wire L and a lamp wire L1 and used for controlling the on-off of a load, wherein an impedance unit used for controlling impedance, a power-taking unit used for taking power and outputting power and a main switch control unit used for controlling on-off ofthe main switch are further connected between the live wire L and the lamp wire L1 in series in sequence, the power-taking unit supplies power to a main control unit, and after the instruction input end 6a of the main control unit receives a working instruction, an impedance control unit is driven to control the impedance unit to reduce impedance, so that the circulating current of the main switchcontrol unit is increased to control the main switch to be switched on. According to the invention, when the load is disconnected or connected with the power supply, the input voltage change of the power-taking unit during power taking is small, so that the power-taking unit with large high and low input voltage change does not need to be designed, the current of the power supply flowing throughthe load in the off state can be reduced, and flickering and slight lighting of the load lamp are prevented.

Description

[technical field] [0001] The invention belongs to a wall switch, and in particular relates to a wall switch circuit for anti-flash and single-fire power-taking. [Background technique] [0002] With the advancement of electronic technology, smart wall switches have appeared on the market. The active functional units in smart wall switches need to obtain working power to work, but most of the existing wall switches only have live wires and light wires, and there is no neutral wire. The power of the unit can only be connected in series with the load, which is the so-called single fire power. This allows the smart switch to have current flow through the load lamp when it is in the off state. Therefore, the existing smart switches on the market, when there is no ground wire in the wall switch, have clear requirements on the power of the connected load lamps, that is, the current flowing through the load lamps in the off state cannot be greater than the load lamps to flicker or l...
