  • 1. Is an LED driver just a power supply?

    Not exactly. Although the LED driver does provide power, it is more than just a simple power converter. It also contains complex circuits to accurately control the output voltage and current, and sometimes includes dimming, temperature protection and other functions.

  • 2. Can I run an LED without a driver?

    Yes, but additional circuits (such as resistors) are required to limit the current. However, this method is less efficient and difficult to maintain a stable current, which may lead to poor LED performance or shortened life.

  • 3. Do all LED lights need a driver?

    Not all LED lights require independent drivers. Some small or integrated LED lamps may already have built-in driver circuits. However, for most high-power LEDs or applications that require specific current control, using a dedicated driver is very necessary.

  • 4. Are there LED drivers with audio output?

    Some high-end LED drivers do have the ability to synchronize with audio signals and change the lighting effects to the rhythm of music. This type of driver is usually used in occasions such as entertainment lighting or stage lighting.
