While LED is shining brightly, LED driver power is of utmost importance in the development of the LED industry chain. The lifespan and reliability of LED driver power directly affect the longevity of LED light sources. So, as the LED industry chain continues to integrate and develop, the maturity of LED driver power technology plays a decisive factor. Due to the rapid development of the LED industry, it has gradually shifted from government lighting to civilian lighting. Thanks to a series of policies recently introduced by the country to encourage the development of the LED industry, many problems have also emerged, such as the problem of LED driver power supply. The LED driver power supply market is closely related to downstream industries, especially the development of high-power LED street lights. However, with the continuous improvement of LED performance parameters, the LED lighting market has gradually emerged and its application fields have become more extensive. Especially in 2012, the industry's focus shifted from outdoor to indoor commercial lighting applications. At the same time, domestic and foreign markets and customers have higher requirements for LED driver power supplies, especially in terms of power efficiency, power factor, lifespan, constant current accuracy, electromagnetic compatibility, and other performance. As the application of LED will gradually shift from government engineering led to civilian lighting led, the application of LED will gradually be subdivided. Although the claim that a single LED has a lifespan of up to 100000 hours has been shattered, LED driver power has not yet kept up with the actual lifespan of LEDs. The impact on the promotion of LED lighting products is due to the fact that the lifespan of the LED driver power supply itself directly affects the lifespan of LED lighting fixtures; Or the low efficiency of the driving power supply may lead to low efficiency conversion of LED lighting fixtures; Or it may be due to the instability of output current and voltage, which affects the luminous quality and greatly undermines the green and energy-saving advantages of LED lighting, thereby affecting the popularity of the market.
In order to overcome the issues of heat dissipation and lifespan of LED driver power supplies mentioned above, the solution for LED driver without electrolytic capacitors will become the ultimate choice in the market. The future LED driver power supply will develop towards stability, safety, high efficiency, no electrolytic capacitors, and highly integrated small volume.
