The luminous efficiency of LED bulb is higher than that of incandescent bulb, and is expanding its range of applications at a faster speed. Large size liquid TV backlight, automotive, commercial and industrial lighting have gradually become the main application fields of LED. With the efforts of many enterprises and government departments, China's LED industry has initially formed four regions in the north, such as the Pearl River Delta, the Yangtze River Delta, the southeast, Beijing and Dalian, and each region has basically formed a relatively complete industrial chain. In general, the south of China's LED industry pattern has a high degree of industrialization, while the north relies on many universities and scientific research institutions.
Strong R & D strength. In terms of geographical distribution, the bulb Market in the Pearl River Delta and Yangtze River Delta is the most concentrated area of domestic LED industry, with more than 80% of relevant enterprises in China. It is also the fastest developing area of domestic LED industry, and its comprehensive industrial advantages are obvious. Equipment and raw material suppliers related to the LED bulb market have settled in these two regions one after another, and the convenient connection with the international application market is the LED bulb market. In the future, China will carry out ten energy-saving projects, among which green lighting and the promotion of high-efficiency power-saving lighting system will be an important content. Therefore, as the fourth lighting revolution after open flame, incandescent bulb and fluorescent bulb, LED lighting market will become the technical development trend in the next few years.
