    Tips: What is a LED driver?

    A LED driver, also known as an LED power supply or LED transformer, is a device that regulates and provides the necessary electrical power to light-emitting diodes (LEDs). LED drivers are specifically designed to match the electrical requirements of LEDs and ensure their proper operation.

    LEDs are semiconductor devices that require a specific voltage and current to function optimally. Unlike traditional incandescent or fluorescent lamps, LEDs are more sensitive to variations in voltage and current. LED drivers address these requirements and provide the appropriate electrical parameters for reliable and efficient LED operation.
