Triac technology is a technology with more than half a century. After the Triac dimming technology, the lighting industry has adopted 0/1-10V analog dimming, DMX512 and DALI and other PWM digital dimming protocol technologies.

However, Triac dimming technology has its irreplaceable reasons. One is due to historical inheritance, and the other does not require signal lines and does not need to change the simplicity of the original lines. The cost is low and the construction is convenient. It is more popular with the engineering side, so it can Triac dimming power supply still occupies the largest market share of dimming power supply. So what is Triac dimming power supply?

Triac was originally just a discrete device, commonly known as thyristor. Because of its unique structural characteristics, it is widely used in traditional fan speed regulators and halogen lamp dimmers. The general shape is designed as the national standard 86 type.

so most of them call it a cutting-edge Triac dimmer, and most of the Triac edge dimmer switches designed using MOS tubes are also called Triac dimmers. In the period of rapid development of LED lamps, The driving power used with the Triac dimmer is collectively referred to as the Triac dimming power supply.
