LED开关电源的发展趋势

（1） High conversion efficiency and power factor

1. High conversion efficiency refers to the utilization rate of the power supply to the power grid. With the development of science and technology, the demand for electric energy also increases, which requires high conversion efficiency of the energy conversion device (power supply);

2. Power factor - high power factor reduces the burden of energy transmission in the power grid.

（2） Small size and light weight

With the continuous development of the industry, the identification or lighting products are becoming more and more refined, smart and small. The size of the power supply matched with them also needs to be miniaturized and light-weight.

（3）Modular and intelligent power supply

Modularization is the general trend of power supply development. Modular power supply can be used to form a distributed power supply system, which can be designed into multiple one redundant power supply systems, and realize capacity expansion in parallel mode, so as to achieve intellectualization.
