    FAQ

    Q1: Why can't a regular power supply be used directly as a power supply for LEDs?

    While a regular power supply can power LEDs in some situations, LEDs are inherently current-driven devices, and even small changes in current can significantly affect brightness and lifespan. Regular power supplies typically lack the precise control capabilities for LEDs; unstable input voltage or changes in load can lead to overcurrent, severe overheating, or even direct damage to the LED. In contrast, dedicated LED power supplies are better suited for lighting applications in terms of control precision and protection functions.

    Q2: What do LED driver input and output voltages mean?

    The input voltage of an LED driver refers to the range of power supplies that the power supply can be connected to, commonly AC100–240V, to adapt to the mains power conditions of different countries and regions. The output voltage, on the other hand, is the operating voltage or voltage range provided by the power supply to the LED lighting fixture. Correctly understanding and matching the input and output parameters is a crucial step in ensuring the normal operation of LED lighting fixtures and the safe operation of the system.
