Phase-cut dimming control device, method and readable storage medium

Abstract

The present invention provides a phase-cut dimming control device, method and readable storage medium. The zero-point information is obtained by controlling the detection action of the zero-point detection circuit, and the phase-cut control circuit and lighting equipment are controlled according to the zero-point information. connected / disconnected, and / or used to receive the dimming instruction and send it to the phase-cut control circuit to control its connection / disconnection with the lighting device. The invention can provide dimming control that can be networked, dimmed, and turned off, and can quickly, stably, and low-interference intervene in various network platforms and electronic equipment.

Description

technical field [0001] The present invention relates to the technical field of lighting control, in particular to a phase-cut dimming control device, method and readable storage medium. Background technique [0002] At present, there are many traditional lamps in the market without dimming function. At the same time, these lamps cannot be connected to the Internet platform for dimming and shutdown, and remote control cannot be realized. With the maturity of phase-cut dimming technology, the development of various communication modules, and the popularization of embedded micro-control systems, intelligent lighting equipment or systems are gradually replacing traditional lighting control methods. [0003] At present, mainstream dimming technologies include leading-edge dimming and trailing-cut dimming. Because leading-edge dimming technology has the advantages of high adjustment accuracy, high efficiency, easy operation, and low cost, it gradually occupies a dominant position....

Problems solved by technology

[0003] At present, mainstream dimming technologies include leading-edge dimming and trailing-cut dimming. Because leading-edge dimming technology has the advantages of high adjustment accuracy, high efficiency, easy operation, and low cost, it gradually occupies a dominant position. High-frequency harmonic interference and low-frequency noise will be generated at the moment of conduction. In the current environment full of electronic equipment and smart home appliances, when the interference generated is serious, it will cause the surrounding electronic equipment to fail to work normally. In the long run, there will be a large In addition, because the front-cut phase dimming technology has a minimum load requirement, it cannot completely turn off the segment current
