2、 Research on the Three Major Camps of Global LED Chip Markets

LED lighting chips, as the core chain of the upstream industry, the development of technology will directly drive changes in the lighting market pattern. Currently, the global LED chip market format is divided into three major camps, and its global sales ranking is: I

The first camp: Japan, Europe and America are representative manufacturers: the world's five major LED giants all belong to this camp, including Nichia Chemical, Toyota Synthetic, Lumileds, Cree, and Osram. This camp also includes Toshiba, Panasonic, and Sharp. This camp has first-class technology, rich patents, and has been working in the field of ultra-high brightness LED for many years. Its target markets are general lighting and automotive lighting. Japanese companies tend to balance a small amount of LED backlighting for consumer electronics products, while European and American companies have no interest in LED backlighting for consumer electronics products.

Second camp: manufacturers represented by South Korea and Taiwan, China. This camp of manufacturers has a complete industry chain in consumer electronics, focusing on LED backlighting for consumer electronics products. Their technology lags behind European, Japanese, and American companies, especially in the field of general lighting, which is currently enjoying a period of rapid growth.

Third camp: manufacturers represented by Chinese Mainland. The manufacturers in Chinese Mainland are small in scale and scattered in number. They are mainly engaged in the production of quaternary yellow green LED, mainly used for outdoor landscape, decoration or advertising. In 2009, the total output value of China's LED chip industry was over 2 billion yuan, with 62 enterprises divided by region. Among them, 15 provinces/municipalities directly under the central government entered the LED chip industry, and the number of enterprises in Guangdong and Fujian was significantly ahead of other regions. Guangdong had 10 enterprises accounting for 16.1%, while Fujian had 8 enterprises accounting for 12.9%. 7 provinces/municipalities where national semiconductor lighting industrialization bases are located have a total of 4 or more LED chip enterprises. There are a total of 41 LED chip enterprises in Guangdong, Fujian, Shanghai, Hebei, Jiangsu, Jiangxi, and Liaoning provinces/municipalities where 7 national semiconductor lighting industrialization bases are located, accounting for about 2/3 of the total number of LED chip enterprises. The number of LED chip enterprises in Shandong, Hubei, and Zhejiang is also above 4.
