The development status of LED light drive power

While LED shines, LED drive power is the top priority of the development of the LED industry chain. The life and reliability of LED drive power directly affect the long life of LED light source. 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 direction of government agency lighting to civil lighting. It has benefited from a series of policies recently issued by the country to encourage the development of the LED industry, but this has also brought many problems. The problem is exposed. The LED drive 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 the application fields have become more extensive, especially in 2012. While shifting from outdoor to indoor commercial lighting applications, domestic and foreign markets and customers also have higher requirements for LED drive power, especially the efficiency, power factor, life, constant current accuracy, electromagnetic compatibility and other performance of the power supply. As the application of LED will gradually change from government engineering dominance to civil lighting dominance, 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 been exploded, the LED drive power supply has indeed not kept up with the actual life of the LED. The promotion of LED lighting products is affected because the life of the LED driving power supply itself directly drags down the life of the LED lighting fixture; or the low efficiency of the driving power supply leads to low efficiency conversion of the LED lighting fixture; or the instability of the output current and voltage affects the light emission The quality of LED lighting greatly reduces the green energy-saving advantages of LED lighting, thus affecting the popularity of the market.

In order to overcome the heat dissipation and lifespan problems of the above-mentioned LED drive power supply, electrolytic capacitor-free LED drive solutions will become the ultimate choice in the market. The future LED drive power supply will develop towards the trend of stability, safety, high efficiency, no electrolytic capacitors, high integration and small size.
