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. 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.
-
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.
