Basic Knowledge about Different Kinds of LED Power Supplies

Although LED’s power saving efficiency is higher than ordinary light sources, it can not be connected directly to public grid voltage like those ordinary ones. It should be configured with special voltage switching device which can supply it with rated voltage and current, providing a sound condition for it to function in normally. That is the so-called special power supply for LED.
