Abstract

An intelligent TRIAC dimmer includes an RF receiving circuit for receiving an external control command; a phase cutting circuit for a phase cutting power line; a control chip for driving a phase-cutting circuit to perform phase-cutting according to an external control command; a Zero-crossing detection circuit for zero-crossing detection; an overcurrent detection circuit for overcurrent detection;and a power supply circuit; The RF receiving circuit signal input terminal receives the external command signal, and the signal output terminal transmits the received external control command to thecontrol chip. The power input terminal L is connected with the control chip through a zero-crossing detection circuit, and the power input terminal L is connected with the control chip through a phasecutting circuit. A load output terminal is connected with that control chip through a zero-crossing detection circuit, and a load output terminal is connected with the control chip through a phase cut circuit. The invention adopts two-wire power fetching, so that the phenomenon of LED lamp flickering does not occur; With the addition of WIFI module, the wireless dimming function can be realized,and the user can control it remotely, which makes it more flexible and convenient to use.

Description

technical field [0001] The invention relates to the field of LED dimming, in particular to an intelligent TRIAC dimmer which is compatible with LED lamps and has a wireless control function. Background technique [0002] TRIAC has a large market share. (1) Traditional TRIAC dimmers are basically adjusted by mechanical knobs or mechanical sliders, which are not flexible enough to use. (2) The traditional TRIAC dimmer uses single-phase power supply. When the LED light is dimmed, the current flowing through the TRIAC dimmer is too small to maintain the normal operation of the TRAIC dimmer. At this time There will be a flickering phenomenon of the LED light, that is, the incompatibility between the TRIAC dimmer and the LED light. [0003] Chinese Patent Publication No. CN 103313472B, the authorized announcement date is February 03, 2016, the name of the invention is an LED drive circuit and lamp with dimming function, the application discloses a LED driver with dimming function...
