1: Thyristor dimming, a dimming technology developed from incandescent lamps, can be achieved smoothly due to the pure resistive load of incandescent lamps. However, it is not practical for LEDs. From a dimming power supply compatible with thyristors, the efficiency is usually very low, with 80% being difficult to achieve, which goes against the original intention of LED energy-saving. Secondly, it is difficult to achieve high power factor, and can only work under a single input voltage, This dimming technology will inevitably die out due to the disappearance of incandescent lamps, but due to its high market penetration, it will still exist for some time.
2: Linear dimming utilizes the dedicated dimming foot of a constant current chip to adjust the current of the LED to achieve dimming. This technology has a good effect, but the wiring is complex and not conducive to lighting such as fluorescent lamps and street lamps. Many desk lamps use this method.
3: PWM dimming is similar to linear dimming, and together with linear dimming, it occupies the majority of the dimming table lamp market. This PWM dimming is also very enjoyable for both users and customers.
4: Remote dimming can be divided into infrared remote control and wireless remote control, which are relatively complex to achieve, but can achieve effects that cannot be achieved by other dimming methods such as changing color temperature and color. It is mainly used for dimming panel lights, and some bulb lights also use some dimming methods.
