Development status of LED drive power

by:MOSO     2019-12-11
At the same time that LED shines, LED drive power is the top priority in the development of the LED industry chain. The life and reliability of LED drive power directly affect the long life of LED light sources. Therefore, while the LED industry chain continues to integrate and develop, the maturity of LED drive power technology plays a decisive factor. Due to the rapid development of the LED industry, it has gradually shifted from the lighting direction of government agencies to civilian lighting. Thanks to a series of policies recently issued by the country to encourage the development of the LED industry, it has also brought many problems. The problem was exposed. The LED driving power market is closely related to the development of downstream industries, especially high-power LED street lights.However, with the continuous improvement of various performance parameters of LEDs, the LED lighting market has gradually emerged and its application fields have become more extensive, especially in 2012. From outdoor to indoor commercial lighting applications, domestic and foreign markets and customers have higher requirements for LED drive power, especially power efficiency, power factor, life, constant current accuracy, electromagnetic compatibility and other performance. As the application of LED will gradually change from government-led to civil lighting, the application of LED will gradually be subdivided. Although the claim that the life of a single LED is as long as 100,000 hours has exploded, the LED driving power has indeed not kept up with the actual life of the LED. Affects the promotion of LED lighting products because the life of the LED driving power itself directly drags the life of the LED lighting fixtures; or the efficiency of the driving power is not high resulting in a low efficiency conversion of the LED lighting fixtures; or the instability of the output current and voltage affects light Quality has greatly reduced the green energy saving advantages of LED lighting, which has affected the popularity of the market. [1] In order to overcome the problems of heat dissipation and life of the LED driving power, the electrolytic capacitor LED driving solution will become the final choice of the market. In the future, LED drive power will develop towards stable, safe, high efficiency, no electrolytic capacitors, highly integrated and small size.
