1. Can I run an LED without a driver?
Yes, but additional circuits (such as resistors) are required to limit the current. However, this method is less efficient and difficult to maintain a stable current, which may lead to poor LED performance or shortened life.
-
2. 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.
-
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.
