An LED driver is an electronic device that regulates the power supplied to LEDs (Light Emitting Diodes). It ensures that the LEDs receive a consistent voltage and current, which is essential for their proper functioning and longevity. Without a driver, LEDs may receive too much power, leading to overheating and failure. LED drivers come in various types, including constant current and constant voltage drivers. They are used in a wide range of applications, from residential lighting to large-scale commercial installations. By providing the right power, LED drivers help maintain the efficiency and brightness of LED lighting systems.
