Market research for=pagetitle
Second, the global LED chip three camp market research LED lighting chip as the upstream industry core chain, the development of technology will directly drive the changes in the lighting market structure, the current global LED chip market format is divided into three camps, its global sales ranking:
I first camp: Japan, Europe and the United States as representative manufacturers.
The world's top five LED giants belong to this camp, including Nichia, Toyota Synthetic, Lumileds, Cree and Osram. The camp also includes Toshiba, Panasonic and Sharp. This camp is top-notch and patent-rich, and has been working in the field of ultra-high brightness LED for many years. The target market is general lighting and automotive lighting. Japanese companies will take a small amount of LEDs for consumer electronics backlights, while European and American companies are not interested in LEDs for consumer electronics backlighting.
II second camp: manufacturers represented by Korea and Taiwan.
The manufacturers of this camp have a complete industrial chain of consumer electronics, focusing on LEDs for backlighting of consumer electronics products. The technology has a gap with European, Japanese and American companies, especially in the field of general lighting, and is currently enjoying high-speed growth.
The third camp of III: the manufacturer represented by mainland China.
The manufacturers in mainland China are small in scale and scattered in quantity. They are mainly engaged in the production of quaternary yellow-green LEDs, which are mainly used for outdoor landscapes, decoration or advertising. In 2009, the total output value of China's LED chip industry was more than 2 billion yuan. The number of enterprises by region was 62, of which 15 provinces/municipalities entered the LED chip industry. The number of enterprises in Guangdong and Fujian was significantly ahead of other regions. The number of LED chip companies is 4 or more in Fujian, which has 8 provinces/municipalities in which 12.9.7 national semiconductor lighting industrialization bases are located. A total of 41 LED chip companies in Guangdong, Fujian, Shanghai, Hebei, Jiangsu, Jiangxi, and Liaoning provinces with 7 national semiconductor lighting industrialization bases account for 2/3 of the total number of LED chip companies. Shandong, Hubei, Zhejiang The number of LED chip companies is also four.
