Although most of the malfunctions of LED lamps occur on the power supply, they cannot blame the power supply companies. This also shows that the reliability of LED power supply is also closely related to its application field. The application of LED products will gradually shift from government engineering to civilian lighting, and LED applications will be gradually subdivided.
Although the claim that the lifetime of a single LED is as long as 100,000 hours has exploded, the LED driver power supply has not yet caught up with the actual life of the current LED. According to Hong Dasheng, chairman of Taiwan's Donglin Group (HEP), which focuses on dimming technology, there are dozens of components in the LED driver. Every small component will affect the whole of the driver as long as it has a problem, which in turn affects the entire lamp. Life expectancy. At present, some good LED driver power supply life can reach 2-3 million hours, HEP can be achieved, and currently HEP has modulated 50,000 hours of LED driver power in the experimental stage to cooperate with the extension of LED full-lamp use. Life expectancy, it is expected that mature products will be launched in the next three years.
So for LED power companies, in order to reduce power failures, in addition to full interaction with people in various fields of the industry, how to better use their own advantages, intensive cultivation, and play a role in the segmentation field, is also worth the next in 2012. Carefully planned questions. Liu Muqing, vice chairman of the Shanghai Lighting Society and professor of the Institute of Electric Light Sources of Fudan University, also stressed that LEDs should be compatible, interchangeable and modular in functional lighting applications. , normalization and standardization.
Needless to pay attention to any complexity brought by solid-state lighting, products that are easy to get started 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 system in the future. With the development of technology and the maturity of the market, the formulation of industry standards is imperative. The mature and perfect standards are the basic guarantee for the healthy development of the LED industry, and the modular products of constant voltage and constant current integration will become mainstream, and the products will also be Gradually increase the effectiveness of intelligent control.
