In the past ten years, China's LED industry, especially the high-brightness LED industry, has experienced the introduction of the first quaternary AlGaInP / GaAs MOCVD equipment and the first GaN MOCVD equipment, and developed the first bright red and yellow light epitaxial materials And the first piece of bright blue and green epitaxial materials, produced the first batch of LED chips (devices) for traffic lights, to large quantities for landscape lighting, display screens, backlights, and current road lighting, Tunnel lighting and indoor lighting, etc., LED has developed from the initial signal and indication applications to the current widely used in indoor and outdoor high-brightness display and lighting fields, the industrial white light effect has developed from the initial ten lm / W to the present 130lm / W. The product has covered all application fields Due to the energy-saving, environmental protection, long life and flexible use of LEDs, LED products have expanded from initial signals and indications to display screens, landscape lighting, backlight applications and general lighting. They are widely used in indoor and outdoor large-screen displays and urban architectural landscapes. Lighting, backlights for mobile phones, notebooks, TVs, automotive lamps and solar LED lighting, road lighting, tunnels, industrial and mining lighting and some special lighting applications are also constantly expanding penetration. After ten years of development, the application of LED products in China has covered all the above-mentioned application fields, and more and more new applications have been developed. In the past two years, more and more investment in research and development in the fields of agricultural production, artificial light sources, medical light sources, etc., as more and more countries announced the implementation of the phase-out incandescent lamp program, with the continuous improvement of LED performance and Prices continue to decrease, and energy-saving and environmentally friendly LEDs are gradually entering the field of general lighting. Gas stations, underground parking lots, hospitals, hotels, clubs, commodity display cabinets, office buildings and other commercial places have taken the lead in using white LEDs as general lighting. At the same time, the technical level of China's LED industry has also been significantly improved. In particular, the Nanchang University Materials Research Institute with independent intellectual property rights has successfully developed a blue-substrate transfer substrate using a silicon substrate and creatively developed a silicon substrate LED technology route. , Changed the situation of Japan and the United States and other countries monopolizing the core technology of LED lighting. Up to now, the luminous efficiency of silicon-based high-power LED chip products that Jingneng Optoelectronics has put on the market has exceeded 120lm / W, and it is the only company in the world that has realized mass production of silicon-based LED products. Equipment and talent are the bottleneck The lack of core technology restricts the development of enterprises. LED core technology is mainly epitaxial growth control, chip structure design and manufacturing process, etc. These core technologies are monopolized by a few foreign companies and are protected for a long time in the form of patents, so that China's technological development is in a very passive situation. The export of products is restricted, and the technological upgrading and product updating of enterprises are limited. Most of the products of enterprises are at a low level of homogeneity for a long time, forming a vicious competition situation. The size of the enterprise is still small. The characteristics of domestic LED companies are: the number of companies is small and the scale is small. Whether it is the epitaxy of the pre-process, the chip, or the packaging and application products of the post-process, this structure is the form. Even the largest domestic LED companies, and Compared with overseas and foreign counterparts, its scale is still much smaller. By the end of 2011, none of the domestic LED companies in the upper and middle reaches has more than 1 billion yuan in main revenue. This form of enterprise will lack R & D strength, product grades will be low, and it will lack competitiveness in the market. Is very unfavorable. Key raw materials and equipment cannot be self-sufficient. Most of the major equipment and instruments in China's LED industry chain currently rely on imports. Key raw materials and supporting parts, such as phosphors, sapphire, organic sources, arsenic, and phosphorane, must rely on imports. MOCVD epitaxy equipment and some fully automated chips and packaging equipment also rely on imports, and the price is high. High-performance silicone and epoxy for encapsulation must also be imported. In the long run, the cost of products will be too high and uncompetitive, which will restrict the entire process of LED industry development. The core technical talent is lacking. There is a lack of domestic leading talents to master the core technology of LED, and there are not enough talents to master the key technologies in all links of the LED industry chain. This will restrict the technological upgrading of China's LED industry and make it difficult to confront foreign counterparts. Lighting is the ultimate LED market The LED industry has experienced an imbalance in the upstream and downstream production capacity structure caused by the investment of the pile. The production capacity scale and the market demand scale are seriously mismatched, and the expansion of market demand is not as expected, resulting in a phased overcapacity. In order to seize the market, Enterprises are fighting price wars, and SMEs are struggling. Although the problems continue, after the baptism of the market, the LED industry is consolidating the foundation and will surely usher in a more healthy and rapid development. In terms of market trends, it can be predicted that in the next five to ten years, the LED market will be mainly indications, display screens, backlights, and lighting, among which the lighting market is the largest and the ultimate market for LEDs. With the decrease in the proportion of incandescent lamps year by year, the future LED industry market is mainly based on commercial lighting and mass consumption. Indoor lighting will be the last huge market for LED applications. In terms of technological development trends, luminous efficiency will be further improved, and technological development will still focus on improving electro-optic conversion efficiency and reducing costs. LED light efficiency will always be guided by technological innovation until it reaches the theoretical limit. Sapphire's non-substrate transfer technology, silicon carbide substrate transfer technology, and silicon substrate technology have great room for technological development. In order to improve the electro-optical conversion efficiency of LED packaging, the development of high-refractive-index encapsulation colloids and phosphors with high excitation light efficiency will become the development trend of packaging technology. The epitaxial chip process technology will accompany the development of sapphire substrates from 2 inches to 3 inches, 4 inches, and 6 inches. Sapphire substrates of 4 inches and above will push the price of LED epitaxial chips and end products down. The price of LED products showed an overall downward trend. With the gradual release of the new production capacity of sapphire substrate manufacturers and the emergence of scale effects, the price of sapphire substrates has further decreased, and the mature use of large-size sapphire substrates larger than 3 inches will continue to reduce the price of chip products; MO source Localization is also a reason for the price reduction of LED chips; in the packaging process, low-cost, easy-to-use and diverse design of COB packaging, and the emergence of new packaging technologies will also greatly reduce the price of LED products. Many LED manufacturers believe that the price of LEDs will fall at an average annual rate of 30% or higher. If this rate can be maintained, by 2015, LED lights will fall to the same price level as incandescent bulbs. Enterprises with better competition are better. The competition of enterprises is mainly reflected in the two aspects of technology and cost. The market competition through product performance and price ratio is the survival of the fittest. In order to obtain technological advantages, companies are competing to increase investment in research and development, in order to continuously improve the technical performance of LED products, adapt to and meet market demand; through continuous improvement of production processes and production management to reduce costs, in order to obtain cost competitive advantages; Increase investment to expand the scale of production or extend to the upstream and downstream of the industry in order to obtain a competitive advantage in economies of scale. We believe that China's LED companies will continue to grow in the competition. In the next few years, whether it is a price war or a brand war, more companies will win and grow into leading companies in the LED industry.
