How to compare LED switching power supply with traditional power supply?

LED switching power supply is controlled by high-speed switching circuit. Is to convert direct current into high-frequency alternating current to transform the converter, so that it can generate one or more sets of required voltages! The efficiency of high frequency alternating current in transformer circuit is higher than that of commercial power 50Hz or 60Hz, so the volume of switching power supply transformer can be very small, and the switching power supply will not be very hot when working, and the product price is lower than that of power frequency DC regulated power supply. If 50Hz or 60Hz is not converted into high frequency electricity, then switching power supply is meaningless. Switching power supply can be roughly divided into isolated and non-isolated types. The isolated type must have an LED switching power converter, and the non-isolated type may not. Compared with the traditional DC power supply, Liangcheng power supply has the advantages of small volume, light weight and high efficiency.
