Product Specifications

Technical details and manufacturing context for Driver / Power Supply

Definition
A critical electronic component within LED RGB/RGBW lighting systems that converts incoming AC power to regulated DC power, controls current flow to the LEDs, and manages color mixing and dimming functions for RGB/RGBW applications. It ensures stable operation, protects LEDs from voltage fluctuations, and enables programmable lighting effects.
Working Principle
The driver/power supply receives alternating current (AC) input, rectifies it to direct current (DC), then regulates voltage and current to match LED requirements. For RGB/RGBW systems, it includes additional circuitry to independently control red, green, blue (and white) channels, allowing color mixing through pulse-width modulation (PWM) or constant current reduction. Advanced drivers incorporate microcontrollers for programmable lighting sequences and communication protocols (DMX, DALI, etc.).
