The Driver / Power Supply is a critical electronic component within LED RGB/RGBW lighting systems. It converts incoming alternating current (AC) power to regulated direct current (DC) power, controls current flow to the LEDs, and manages color mixing and dimming functions for RGB/RGBW applications. This ensures stable operation, protects LEDs from voltage fluctuations, and enables programmable lighting effects. The driver receives AC input, rectifies it to 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 such as DMX and DALI. Typical parameters include input voltage of 100–240 V AC, output voltage of 24 V DC ±10%, output current of 0.35–2.0 A, output power of 15–60 W, efficiency of 85–92%, power factor of 0.9–0.99 (per IEC 61000-3-2), operating temperature of -20 to 50 °C, storage temperature of -40 to 85 °C, IP rating of IP20–IP67 (per IEC 60529), dimming range of 1–100%, dimming interface of 0–10 V DC (also supports DALI/PWM), dimensions of 150×40×30 mm (typical for 60W model), and weight of 200–500 g. Materials typically include printed circuit board (PCB), semiconductors (MOSFETs, ICs), electrolytic capacitors, ferrite core transformers, and aluminum heat sinks. These values are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application.
