LED power supply is an important part of LED lighting system. During the use of LED power supply, a certain amount of heat will be generated according to the design of LED power supply, and heat is the biggest killer of LED power supply light decay. Therefore, if you want the heat to be small and not obvious, the efficiency must be high. This requires a high-efficiency LED power supply. The efficiency of the whole power supply determines the heat generation of the power supply itself. So, what are the specific reasons why LED power supplies need high efficiency?

1. The first reason, of course, is because it can save energy;

2. The high efficiency of the LED power supply can reduce the power loss. For example, an LED power supply with an output power of 150w, when the efficiency reaches 95%, its loss is 7.9w, and when the efficiency is only 85%, its loss is 26.5w ;

3. The high-efficiency power supply can prolong its service life and greatly improve its reliability;

4. If the LED power supply can achieve high efficiency, it can significantly reduce the operating temperature of the LED lamps and delay the light decay.
