LED power supply, also known as LED driver, is a device used to convert the main power supply into a low-voltage direct current (DC) that is required to power LED lighting systems. It provides a stable and regulated current to the LEDs, ensuring their longevity and optimal performance. LED power supplies can be either constant voltage or constant current, depending on the LED system's requirements. They also come in various sizes and wattage ratings, and can be customized to match the specific needs of the LED system. LED power supplies are an essential component of LED lighting systems and play a crucial role in ensuring their reliability and efficiency.
