A LED power supply or LED transformers, often referred to as an LED driver, is a device that regulates the power to LED lighting systems. It converts higher voltage AC or DC power to low voltage DC power suitable for LEDs, ensuring they receive a steady and appropriate amount of current. LED drivers are crucial for the longevity and performance of LED lights, providing constant current or voltage depending on the type of LEDs used. Do you have any specific questions about LED power supplies?
