LED Drivers | Power Supplies for LED Lighting

LED Drivers and Power Supplies
LED drivers regulate power to LED lighting systems, converting line voltage to the low voltage DC current required for optimal LED performance. These electronic devices protect LEDs from voltage fluctuations and ensure consistent light output while extending fixture lifespan.

Constant Current vs Constant Voltage Drivers
Constant current LED drivers maintain steady current output regardless of voltage changes, ideal for high-power LEDs and fixtures with series-connected arrays. Constant voltage drivers deliver fixed voltage output, typically 12V or 24V, suited for parallel LED configurations and LED strip lighting applications.

Key Specifications

Output Current: Measured in milliamps (mA), determines LED brightness and compatibility
Wattage Rating: Total power capacity the driver can supply to connected LEDs
Input Voltage: AC line voltage compatibility (120V, 277V, or universal input)
Dimming Protocol: 0-10V, TRIAC, PWM, or DALI dimming compatibility
Efficiency Rating: Higher efficiency reduces heat generation and energy consumption

Applications
LED drivers power commercial downlights, track lighting, outdoor landscape fixtures, architectural lighting, signage, and industrial high-bay installations. Selecting the correct driver requires matching output specifications to LED load requirements and ensuring compatibility with existing dimming systems.

Installation Considerations
Driver location affects performance and longevity. Remote mounting in ventilated areas away from heat sources maximizes operational life. Class 2 rated drivers simplify installation by eliminating conduit requirements for low-voltage wiring. Waterproof IP67-rated enclosures enable outdoor and wet location installations.
