An LED driver is an electronic device that regulates the power supplied to LEDs (Light Emitting Diodes). It ensures that the correct amount of current flows through the LEDs, preventing them from burning out or flickering. By converting the input voltage to a suitable level, the LED driver helps maintain consistent brightness and efficiency. LED drivers come in various types, including constant current and constant voltage drivers, depending on the application. They are essential for both residential and commercial lighting systems, providing energy-efficient solutions for illuminating spaces while extending the lifespan of the LEDs.
