LED drive power is a voltage converter that converts power into specific voltage and current to drive LED lights. Usually, the input of LED drive power includes high-voltage power frequency AC, low-voltage DC, high-voltage DC, low-voltage high-frequency AC, etc.waterproof led power supply， The output of the LED driving power supply is mostly a constant current source, that is, the voltage can be changed with the change of the forward voltage drop value of the LED.

Since the performance and conversion efficiency of various LED power supplies with different specifications are different, choosing a suitable and efficient LED special power supply can truly show the high efficiency characteristics of LED light sources. Since the low-efficiency LED power supply itself needs to consume a large amount of power, the energy-saving characteristics of the LED cannot be highlighted in the process of supplying power to the LED. In a word, the LED power supply plays an important role in the stability, energy saving and lifespan of the LED.
