What is an LED Driver? – A Complete Guide by W&T

An LED driver is a crucial component in any LED lighting system. It functions as a power supply that regulates the voltage and current delivered to LED lights, ensuring stable performance, long lifespan, and safety. Unlike traditional lighting, LEDs are sensitive to fluctuations in power. Without a proper LED driver, LEDs can flicker, overheat, or fail prematurely.

How Does an LED Driver Work?

An LED driver converts high-voltage AC power from the mains to a low-voltage DC output suitable for LEDs. Depending on the LED type, it can be constant voltage driver:

• Constant Voltage LED Driver: Maintains a fixed voltage, commonly used for LED strips, modules, and low-power lighting.

Many modern LED drivers also include Power Factor Correction (PFC) and protections against overvoltage, short circuit, and overheating. These features are essential for meeting international safety standards such as CE, UL, and RoHS.

Applications of LED Drivers

LED drivers are widely used in various lighting applications, including:

• Indoor lighting: ceiling lights, downlights, panel lights

• Outdoor lighting: street lights, floodlights, landscape lights

• Commercial and industrial lighting: office, warehouse, factory lighting

• Specialty lighting: signage, display, and automotive LEDs

Selecting a high-quality LED driver ensures energy efficiency, consistent brightness, and extended LED lifespan.
