1. Realizing Power Conversion
LED lights cannot directly use 220V AC power, whereas a driver power supply can convert 220V AC power into low-voltage DC power suitable for LED lights to operate.
2. Controlling the Magnitude of the Current
The brightness of LED lights is related to their power. The driver power supply can precisely output current to adjust the power, thereby achieving regulation and control of LED brightness.
3. Providing Stable Voltage and Current
LED light chips have very high requirements for the stability of current and voltage, and the driver power supply can prevent instability in light emission or changes in brightness caused by fluctuations in current and voltage.
4. Protection Functions.
Better driver power supplies generally have functions such as overcurrent protection, overvoltage protection, short-circuit protection, and overheat protection. When abnormalities occur in the circuit, the driver power supply will automatically cut off the output to prevent damage to the LED chips and the driver power supply itself. This enhances the reliability and safety of the LED lighting system.
したがって, good LED lighting fixtures must be equipped with a good driver power supply.
