After several years of development, my country's LED industry has basically formed a relatively complete industrial chain. At the same time, the formulation of LED lighting-related standards and the establishment of a standard system have also entered a stage of rapid development. At present, domestic standard projects involving LED and semiconductor lighting have basically covered all aspects of the industrial chain such as epitaxial chips, packaging devices, product applications, and testing equipment.

Status quo of my country's LED lighting industry distribution (1)

Driven by the "National Semiconductor Lighting Project", my country has established 7 national semiconductor lighting engineering industrialization bases in Shanghai, Xiamen, Dalian, Nanchang, Shenzhen, Yangzhou and Shijiazhuang. The distribution of domestic LED industry is as follows.

(1) Pearl River Delta: mainly concentrated in Shenzhen, Zhongshan, Foshan, Huizhou, Guangzhou, Jiangmen and Dongguan. The Pearl River Delta region is one of the regions with the most active and fastest development of semiconductor lighting industrialization in China. The packaging and application scale is the largest in China, and it is the closest to the market, with active investment and more transfers from overseas companies. The most obvious competitive advantage is market advantage. At present, the consumption of LED lighting in Guangdong market accounts for 50% of the whole country. Among them, Guangzhou's industrial foundation is concentrated on high-end service platforms such as R&D, testing, and design, as well as downstream packaging. Shenzhen's semiconductor lighting industry has initially formed a complete industrial chain of "sapphire-epitaxial-die-package-application", and Jiangmen is mainly concentrated in the downstream. Packaging, application areas, and has been extended to the upstream and midstream epitaxial chip manufacturing.

(2) Yangtze River Delta: The Yangtze River Delta region represented by Shanghai, Jiangsu, Hangzhou and Ningbo in Zhejiang has strong supporting capabilities for the LED industry, prominent high-end applications, and relatively concentrated talents and funds. Among them, Shanghai has shown a good industrial development trend in semiconductor chip manufacturing and packaging applications, and has formed a relatively complete industrial chain and enterprise group; Jiangsu's semiconductor lighting industry, driven by the development of the electronic information industry, is currently in the semiconductor lighting industry. Packaging and application have begun to take shape; Ningbo has a solid industrial foundation (starting early, and is also a lighting production base) and economic location advantages.

(3) Fujian Triangle: Mainly concentrated in Jiangxi and Fujian regions. The upstream investment in the Fujian Triangle is the largest in China, and the scale of epitaxy and chip production capacity and chip companies is relatively large, and Taiwanese companies have transferred more. Xiamen has good group advantages, talent advantages and location advantages. Jiangxi Province has achieved large-scale production from upstream epitaxial materials, midstream chip manufacturing to downstream device packaging.

(4) Bohai Rim region: The Bohai Rim region represented by Beijing, Tianjin, Dalian, Hebei, etc. has strong R&D strength, concentrated R&D institutions, and has the best epitaxy and chip technology in China. Especially Beijing has obvious advantages in research and development; Dalian has a solid light industry and optoelectronic industry foundation, and the economic location advantage of "the center of the Northeast Asian economic circle".
