LED Drivers
An LED driver is a driving device used to illuminate LEDs stably. In order to keep the luminance of an LED stable, the flowing current needs to be constant. By using an LED driver, the current can be controlled with high accuracy and the change in luminance can be minimized. It also detects LED failures and cable breakages. LED drivers can be classified into linear control type, DCDC type, ACDC type, etc. Select a driver according to the application. The DCDC type can control energy loss by adjusting the voltage. The major light control methods are analog method and PWM method. In the analog method, an electronic volume, a variable resistor, etc. is used for light control. In addition, the PWM method has a wider light control range than the analog method, and it is possible to increase the degree of darkness in particular.
