Triac dimming is mainly used in LED dimming control, and has a very wide range of applications in current LED displays. smarts power has been a leader in the field of Constant voltage LED dimming driver for many years, and has rich research experience in various devices and equipment of LED dimming driver

First, we need to know what triac dimming is. A triac is a high-power semiconductor element with a four-layer structure with three PN junctions, usually using two thyristors for reverse connection. We can derive one of its functions from its full name, which is rectification.

Semiconductor components usually have the characteristics of small size, good stability and high efficiency. In this regard, triac also has these three characteristics. Triac has a very important and wide range of applications in the field of dimming. Triac dimming is a common mainstream device in current stage lighting and ambient lighting. It is environmentally friendly, energy-saving, has long life and no noise. It is a very popular dimming method.

In essence, triac dimming led driver can be regarded as an AC voltage regulator. By adjusting the voltage, the brightness of the light is changed. This dimming method changes the amplitude of the sinusoidal alternating current, but does not change its waveform. At present, LED lighting has been widely used in life and production. The LED lighting method saves energy and resources, and the application of triac dimming technology in LED lighting is also very extensive.
