Principle Of LED Controller-Application

The light-emitting principle of LED is actually very simple, but it can be said that it is very difficult to achieve dimming while ensuring the normal operation of the LED controller. The principle of the LED controller is to realize the adjustment of the LED lamp, and it is necessary to unidirectionally adjust the constant current flowing to the LED. Generally, the controller in this case will have slow startup speed, uneven lighting, and flicker when adjusting the brightness.

We often see all kinds of advertising signs and billboards on the streets. Because there is no LED controller, we can't control the length of flashing time, flashing speed and so on. The LED controller can solve these problems conveniently and simply, because it can control the switches of various positions in the LED lamp circuit, so that the LED array emits light regularly, thereby displaying specific text or graphics. At the same time, the cost is low and it can better serve our customers. LED controllers are widely used in various lighting equipment such as outdoor billboards, Building Lighting decoration, and indoor decorative lighting.
