The working principle of LED lamp and the important role of LED controller
LED lamp usually contains a LED array, and according to the preset program, LED controller can control the switch at each position in the LED lamp circuit and make LED lighten regularly to show a specific text or graphics. LED lamps connect together through series way, and they should be driven by a constant power supply. In the process of using, the current control must 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 first through a compound semiconductor, 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 be taken a unidirectional adjustment. In this case, LED controller will appear some problems 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.
