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. Does an LED strip require an LED driver?
Yes, LED strips usually require a suitable driver to provide the correct voltage and current. Especially for long strips, because they are often composed of multiple small LEDs in series or parallel.
-
3. Can I use an LED light without a driver?
As mentioned before, in theory yes, but in practice it is strongly recommended to use a proper driver to ensure optimal performance and extend life.
-
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.
