Problems solved by technology

These wall switches consume very low power (microwatts of power consumption) in standby, but can rise to tens of milliwatts when the light is on after being touched
When switching between light load and heavy load, it may cause abnormal power supply
If you want to solve this problem, you need to increase the charging time, but this will affect the normal work of the lamp

Abstract

The invention provides a single-live-wire electric power acquisition device which comprises a rectifying unit, a first energy storage unit, a control unit and an adjustable impedance unit. The rectifying unit performs rectification on AC power and outputs DC to the first energy storage unit. The first energy storage unit supplies electric energy to a load. The control unit detects voltage magnitude of the first energy storage unit and controls impedance change of the adjustable impedance unit according to the detected voltage magnitude. The single-live-wire electric power acquisition device automatically adjusts low-impedance time and high-impedance time of the adjustable impedance unit according to power consumption amount of the load for supplying enough energy to the load.

Description

technical field [0001] The invention relates to a single live wire power-taking device and a single live wire switch. Background technique [0002] With the advancement of intelligence in the lighting field, more and more wireless control and man-machine interface are applied. Among them, the wall wireless control panel is a popular controller for home and commercial lighting. Compared with the traditional wall switch, the wall wireless control panel has the advantages of convenient operation and long service life. More and more buildings are replacing traditional wall switches with wall-mounted wireless control panels. [0003] In the actual replacement, it is found that the current wall wireless control panels are powered by two wires, but the traditional wall switches are all connected by single fire wire. The user has to rewire in order to replace it, which is a relatively large project for a room that has been decorated, and the cost is high, thus limiting the applica...
