Abstract

The invention discloses an LED light-emitting device achieving color and light adjustment through a light regulator and a method and relates to the field of LED illumination. The LED light-emitting device comprises an alternating-current input end, the light regulator, a drive circuit, an optical coupling circuit and an MCU, wherein the alternating-current input end is connected with the light regulator, the light regulator is connected with the optical coupling circuit and the drive circuit, and both the optical coupling circuit and the drive circuit are connected with the MCU. The LED light-emitting device further comprises a first LED lamp set and a second LED lamp set, wherein the MCU is connected with the first LED lamp set through a first switching circuit and is connected with the second LED lamp set through a second switching circuit, and the drive circuit provides drive power supplies for the MCU, the first LED lamp set and the second LED lamp set respectively. The LED light-emitting deice achieving color and light adjustment through the light regulator saves cost and is easy to install, color and light adjustment can be achieved without external circuits, and circuits are simple.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lighting device and method for realizing dimming and dimming through a dimmer. Background technique [0002] With the gradual improvement of people's living standards, everyone's yearning and pursuit of visual experience is getting higher and higher. Traditional incandescent lamps consume a lot of power and are gradually replaced by electronic energy-saving lamps. The lamp contains mercury, which will be released into the air after the energy-saving lamp is broken, which will seriously pollute the environment and bring very serious consequences; it is gradually replaced by LED, and the service life of LED lamp is about 50,000 hours; while At present, most of the LED lighting systems on the market use a single switch when controlling multiple LED lights, that is, fully on or fully off. Problems such as turning on the lights are not conducive to energy saving, environmental ...
