What is an LED driver?

An LED driver is an essential electronic component that powers and controls LED (Light-Emitting Diode) lights and fixtures. Its primary function is to convert the available input power, typically from a mains power source, into the correct DC voltage and current required by the LED or LED array. LED drivers maintain a constant current supply to the LEDs, ensuring consistent and stable light output, and often incorporate dimming capabilities to adjust the brightness. They also include safety features like over-voltage and over-current protection to safeguard the LED lights and the power supply. LED drivers are designed to be highly efficient, minimizing energy losses and ensuring the longevity of the LED lighting system.

LED drivers are available in a wide range of sizes, power ratings, and feature sets to accommodate various LED lighting applications, from small, low-power LED lamps to large-scale LED installations in commercial, industrial, and outdoor environments.
