Led dimmer is mainly used for dimming various LED devices. However, depending on the scale of use, the dimmer will have a different dimming system. At present, the dimming system can be roughly divided into segmented switch dimming, remote dimming and intelligent dimming. Here are some of the characteristics of each of them.

Sectional switch dimming

The led dimmer can use the ordinary switch on the wall for four-stage dimming, the first segment is full bright, the second segment is 60% brightness, and the third segment is 40% brightness. The four segments are 20% brighter. This four-stage dimming performance makes the scale of the dimmer more scalable, and it is more convenient to operate than the traditional dimmer.

And its power factor can be as high as 0.92 or more. This feature makes the dimmer not affected by the disturbing signal. Although the segmented switch dimming has many advantages, it also has a significant disadvantage, that is, it cannot Performing dimming in succession is a bit complicated.

2. Remote dimming

Remote control dimming links with the latest modern science and technology, using infrared controller to control the LED. This is the most ideal LED control method. It can remotely complete the switch of LED, and can complete the dimming according to the system setting. We have a very large lunch.

However, the remote control dimming system is adopted, and the investment cost is very large, and the prices of various remote control system devices are relatively high. And now there is no uniform standard for remote control standards on the market, and different manufacturers' products cannot be interoperable. So today the remote control system is still only suitable for high-end residences.

3. Intelligent dimming

Intelligent dimming is a new type of led dimmer system that adapts itself to the environment according to the surrounding environment. For example, a photosensitive dimming system, which is commonly used in streetlights, will reduce the brightness of streetlights during the night to dawn, compared to the brightness of streetlights before twelve o'clock, reducing the cost of electricity.
