1. What is the difference between an LED driver and a ballast?
LED drivers: Designed specifically for LEDs, they are usually used to adjust the output current to meet the requirements of LEDs.
Ballasts: Traditionally used for fluorescent lamps or other gas discharge lamps, they control the high voltage at startup and limit the operating current. Although some modern electronic ballasts can also provide constant current, their original design and application areas are different from LED drivers. -
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. How can I tell if an LED driver is broken?
If the LED does not light up or the brightness drops significantly.
The driver is heating abnormally.
There is a distinct burnt smell.
Measure the input and output voltage/current and it does not meet the specification.
Test the status of its internal components through professional equipment. -
4. 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.
