1: triac dimming. From the current point of view, the dimming power supply compatible with triac is usually very low in efficiency, and it is difficult to achieve 80%, which is contrary to the original intention of LED energy saving.

2: Linear dimming. The special dimming foot of the constant current chip is used to adjust the current of the LED to achieve the purpose of dimming. This kind of technology has a good effect, but the wiring is complicated, which is not conducive to lighting such as fluorescent lamps and street lamps.

3: PWM dimming. This method is similar to linear dimming, and together with linear dimming, it occupies most of the dimming table lamp. This PWM dimming users and customers are also very happy.

4: Remote control dimming. It is divided into infrared remote control and wireless remote control. It is more complicated to realize, but it can achieve the effect that can not be achieved by other dimming methods such as changing color temperature and color. At present, it is mainly used for panel light dimming, and some bulb lights use some kinds of adjustments. Light way.
