1. What is an LED driver for?
The main role of LED drivers is to provide a stable operating current for LEDs. Since LEDs are very sensitive to current, too high a current can cause them to be damaged or their lifespan to be shortened, while too low a current cannot guarantee brightness. Therefore, a suitable driver can ensure that the LED works under safe and efficient conditions.
-
2. 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.
-
3. 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.
-
4. 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.
