1^st : Improve the life and extend the life of the LED fixtures. The overall life of the drive circuit, especially the key components such as: The life of the capacitor at high temperature directly affects the life of the power supply;

2^nd : Improve efficiency and improve the light effect of LED fixtures. UL listed LED drivers should challenge higher conversion efficiency, especially when driving high-power LEDs, because all the power that is not used as light output is dissipated as heat, and the power conversion efficiency is too low, which affects the energy-saving effect of LEDs. ;

3^rd : Reduce costs and improve purchase ability. At present, in the application of low power (1-5W), the proportion of the cost of the constant current drive power supply has been close to 1/3, which is close to the cost of the light source, which affects the market promotion to a certain extent.

The development trend of LED drive power is still quite fast, but the challenge is not simple. Looking forward to the development of LED drive power.
