Intelligent light emitting diode (LED) lamp, system and method compatible with silicon-controlled rectifier dimming

Abstract

The invention discloses an intelligent light emitting diode (LED) lamp compatible with silicon-controlled rectifier dimming. The intelligent LED lamp comprises a silicon-controlled rectifier dimmer, a wireless control module, a phase-cutting signal detection conversion circuit, an LED driving circuit and an LED module. A dimming system compatible with silicon-controlled rectifier dimming comprises the intelligent LED lamp and also comprises an intelligent terminal. A dimming method compatible with silicon-controlled rectifier dimming is applied to the dimming system and comprises the following steps of pairing and connecting the wireless control module of the LED lamp and the intelligent terminal; receiving an instruction input by a user through a customized APP by the intelligent terminal, and sending a wireless control signal to the wireless control module of the LED lamp; receiving the wireless control signal and a signal from the phase-cutting signal detection conversion circuit by the wireless control module, and carrying out comprehensive processing on the wireless control signal and the signal; and giving out a corresponding dimming instruction by the wireless control module to control the LED driving circuit so as to change an output current and complete LED dimming. By such control mode, the technical problem of compatibility can be solved, the cost is relatively low, and the control mode is applied to the field of LED lighting.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an intelligent LED lamp compatible with thyristor dimming, a system and a method. Background technique [0002] Triac Dimmer: A traditional controller that performs phase-cutting of thyristors on sinusoidal power supply waveforms. [0003] At present, the dimmable LED lamps developed by various dimmable LED lamp manufacturers in the market can basically be divided into individual thyristor control dimming, and individual wireless control methods such as RF, BLE or ZIGBEE, and only one of them can be used. The way to complete the dimming function of LED lights, when traditional users have installed Triac Dimmer on the wall, but want to use intelligent control dimming LED lights, there will be incompatibility problems. [0004] The disadvantage of existing LED lights is that they can only use a certain dimming method for dimming control, including the products developed by various firs...

Problems solved by technology

[0004] The disadvantage of existing LED lights is that they can only use a certain dimming method for dimming control, including the products developed by various first-line industry manufacturers that cannot meet the compatibility control with traditional thyristor dimmers, and traditional users want To use intelligent control LED lamps, it is necessary to modify the thyristor dimmer installed on the home wall, otherwise it will not be possible

With the traditional smart LED lamps currently on the market, the thyristor dimmer must be s
