What is led driver?

Generally speaking, the LED driving power supply is a converter. Its function is to convert our commonly used commercial power or other power supply into the voltage and current suitable for LED. Only through its conversion the LED can work normally and emit light. For example, if we want to open a nut, we must use the same type of wrench.

The function of LED driver is no different from the ballast of quartz lamp cup, transformer, fluorescent lamp, energy-saving lamp and metal halide lamp we used in the past. They are all for the stable and normal operation of light source products. So it is often called led ballast, led transformer, etc, but it is generally called drivers by the LED practitioners. One is to distinguish them from other converters. Second, there are differences in their working principles.
