LED (Light-Emitting Diode) is becoming a very important component in modern electronic products. LED has been widely used in the fields of digital display screens, business signs, traffic lights and so on. LEDs have a good surface emitting effect and a wide degree of brightness stability, but it cannot work perfectly in the whole brightness range if it works alone, because it requires more current when operate in high brightness compared with low brightness. Therefore, an LED driver is needed to ensure the LED can work efficiently in the wide brightness range which is regulated through the LED driver.
