LED power classification; 1: According to the power supply voltage: there is a high voltage AC85-265. Low pressure 1. 5- 36V 2: according to the power supply mode, there are constant voltage source and constant current source. 3. According to the isolation relationship between input and output, there are isolated power supply and non-isolated power supply. 4. The relationship between input voltage and output voltage is divided into step-up type, step-down type and up-down type. The development of China's LED industry; China's LED industry started in 1970s. After more than 30 years of development, China's LED industry has initially formed the production of LED epitaxial wafer, LED chip preparation, LED chip packaging, A relatively complete industrial chain including LED power supply and LED product application. With the promotion of 'National Semiconductor Lighting Project', seven national semiconductor lighting project industrialization bases in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang have been formed. The Yangtze River Delta, the Pearl River Delta, the Fujian Triangle and the northern region have become the gathering places for the development of China's LED industry. At present, China's semiconductor lighting industry is developing well, the development of extension chip enterprises is especially rapid, the scale of packaging enterprises continues to maintain rapid growth, and lighting applications have made great progress. The output value of China's LED application products has exceeded 300 yuan in 2007, and it has become the world's largest producer and exporter of LED full-color display screen, Solar LED, landscape lighting and other application products, the emerging semiconductor lighting industry is taking shape. Some characteristics have been formed in the field of lighting in China. Among them, outdoor lighting has developed rapidly, with hundreds of LED street lamp enterprises and dozens of demonstration roads built, however, China still lags behind in terms of large-size LCD backlights and automotive headlamps. The concentrated display of LED lighting in 2008 Beijing Olympic Games gave people a new understanding of LED, which strongly promoted the development of China's semiconductor lighting industry. At present, China's semiconductor industry is large but not strong, and its core competitiveness still needs to be further improved. For domestic enterprises, expanding the scale and improving the product quality and technical level are the primary tasks, so as to improve the asking price ability when obtaining the authorization of brick profits from large factories in the future, or gradually break through the core brick profits through research and development. In addition, the products sold by our company include ARTESYN power supply, switching power supply, etc. Welcome to consult!
