The working principle of LED lamp and the important role of LED controller

LED lamp usually contains a LED array. According to the preset program, LED controller can control the switch at each position in the LED lamp circuit and lighten LED regularly to show a specific text or graphics. LED lamps connect together in series, and they should be driven by a constant power supply.  When using, the current control needs to be strict in order to ensure the LED lamp work normally for the brightness of each LED is determined by current.

The working principle of LED lamp is simple. The current is through a compound semiconductor first, and then by a combination of electrons and holes, the excess energy will be released in the form of light so as to achieve the lighting effect. The brightness of LED lamp is determined by the forward current. In order to achieve adjustable light, LED lamps should take a unidirectional adjustment. In this case, some problems may occur in LED controllers, such as slow start speed, uneven illumination and so on. It is a little difficult to ensure the LED controller work normally when adjusting light.
