The LED lighting industry chain includes upstream raw materials, equipment (single chip) and epitaxial growth; midstream chip manufacturing; downstream packaging and product development, production and application; supporting industries including related equipment, accessories, materials, etc. The upstream link has high technical content, large capital investment, large quality impact, high profit margin, LED luminous color and luminous efficiency are related to the materials and processes for making LED, and upstream accounts for about 70 LED manufacturing costs, which is extremely important for the LED industry; Technology and capital-intensive links, the chip is currently the most fierce part of the patent competition, with the characteristics of strong investment intensity but slow effect; the downstream links include the development and production application of LED packaging and lamps, which is the most closely related link with the market. Relatively low, the investment threshold is also low, so it is the largest and fastest growing field in the LED industry.
The current LED lighting industry status LED lighting industry is in a period of rapid development, the current global LED industry can be divided into four major regions. First, in Europe and the United States, the general lighting is the main direction, emphasizing the high reliability and high brightness of the products. Second, Japan is the most comprehensive technology. Whether it is general lighting or backlit display, it has strong strength, and its development direction takes into account general lighting, automobiles, mobile phones and television. Third, South Korea and Taiwan, with notebook display backlighting, LED-TV backlighting and mobile phone backlight as the main direction, with large shipments, low unit prices and low gross profit. Fourth, the mainland of China, focusing on yellow-green light, focuses on outdoor display, advertising screens, and signal lights.
Under the dual pull of domestic industrial policies and international market demand, China's LED lighting products market is also accelerating. At present, global LED production capacity is shifting to China, and around 50 LED packages and more than 60 LED applications are being carried out in China. China has become the fastest growing region in the global semiconductor lighting industry.
