Due to the rapid development of the LED industry in recent years, it has gradually shifted from the direction of government lighting to civilian lighting. Thanks to the country’s recent introduction of a series of policies to encourage the development of the LED industry, it has also brought many problems. LED The problem of the driving power is exposed. The LED drive power supply market is closely related to the downstream industries, especially the development of high-power LED street lamps. 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 2011, the industry’s attention While turning from outdoor to indoor commercial lighting applications, there are also different requirements for LED driving power.
Although most of the failures of LED lamps occur on the power supply, the power supply company cannot be blamed blindly. This also shows that the reliability of the LED power supply is also closely related to its application field. The application of LED products will gradually change from being dominated by government projects to being dominated by civilian lighting, and the application of LEDs will be gradually subdivided. Although the so-called claim that the life of a single LED is as long as 100,000 hours has exploded, the LED drive power has indeed not kept up with the actual life of the current LED. According to Hong Dasheng, chairman of Taiwan Donglin Group (HEP), which focuses on dimming technology, there are dozens of components in the LED drive power supply. As long as each small component goes wrong, it will affect the entire drive appliance, and then affect the entire lamp. lifespan. As far as the current situation is concerned, some relatively good LED drive power supplies can reach 20,000 to 30,000 hours in service life, and HEP has been able to achieve this. At present, HEP has modulated a 50,000-hour LED drive power supply in the experimental stage to match the extended use of LED lamps. It is expected that mature products will be launched in the next three years。
So for LED power supply companies, in order to reduce power supply failures, in addition to fully interacting with people from various fields in the industry, how to make better use of their own advantages, intensive cultivation, and play a role in subdivided fields are also worthy of consideration in 2012. A matter of careful planning. At the lighting technology forum of the four municipalities held in Tianjin a few days ago, Liu Muqing, vice chairman of the Shanghai Lighting Society and professor of the Electric Light Source Research Institute of Fudan University, also emphasized that LEDs should be compatible, interchangeable and modular in functional lighting applications. , normalization and standardization. Regardless of any complexity brought by solid-state lighting, products that are easy to use will obviously be more popular with users, and modularization and intelligence will bring a lot of convenience to users, which is the mainstream trend of LED lighting systems in the future. With the development of technology and the maturity of the market, it is imperative to formulate industry standards. Mature and perfect standards are the basic guarantee for the healthy development of the LED industry. Modular products with constant voltage and constant current integration will become the mainstream, and the products will also Gradually increase the intelligent control function.
