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. 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. -
3. Why do I need to program an LED driver?
Programming is usually for advanced drivers with programmable functions, such as achieving finer dimming control, color adjustment or other intelligent functions. This allows users to customize the behavior of the driver according to specific needs.
-
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.
