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 high-bright red, yellow epitaxial material and the first A bright blue, green light epitaxial material to produce the first batch of LED chips (devices) for traffic lights, to be used in large quantities for landscape lighting, display screens, backlights, and current road lighting, tunnel lighting And Indoor Lighting, etc., LED has been developed from the initial signal and indication applications to the current widely used in indoor and outdoor high-brightness display and lighting, industrialization of white light efficiency from the initial development of more than a dozen lm/W to the current 130lm /W.
Product has covered all application areas
Due to LED's energy saving, environmental protection, long life, and flexible use, LED products have expanded from initial signals and indications to display screens, landscape lighting, backlighting applications, and general lighting. They are widely used in indoor and outdoor large-screen displays and urban architectural landscapes. Lighting, mobile phones, notebooks, TV backlights, automotive lighting and solar LED lighting, road lighting, tunnels, industrial lighting, and some special lighting applications are also expanding their penetration.
After ten years of development, China's LED product applications have covered all of the above application areas, and more and more new applications have been developed. In the past two years, more and more applications have been invested in the fields of agricultural production of artificial light sources, medical light sources, etc. As more and more countries announced the phase-out of incandescent lamp projects, with the continuous improvement of LED performance and Prices continue to decrease, and energy-saving and environmental-friendly LEDs are gradually entering the general lighting field. Commercial stations such as gas stations, underground parking lots, hospitals, hotels, clubs, merchandise display cabinets, and office buildings 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 Material Research Institute with independent intellectual property rights has successfully developed the substrate transfer blue LED using silicon substrate, and creatively developed the silicon substrate LED technology route. , Japan and the United States changed the monopoly of LED lighting core technology situation. Up to now, the luminous efficiency of silicon-based high-power LED chip products that Jingneng Optoelectronic has introduced to the market has exceeded 120lm/W, and it is the only company in the world to achieve volume production of silicon-based LED products.
Equipment, talent is the bottleneck
The lack of core technology restricts the development of enterprises. The core technology of LED is mainly the control of epitaxial growth, the structural design of the chip and the manufacturing process. These core technologies are monopolized by a few foreign companies and are protected in the form of patents for a long period of time, resulting in a very passive state of technological development in China. The export of products was restricted, and the technological upgrades and product updates of enterprises were limited. Most of the products of the company were in the low-end level of homogeneity for a long time, resulting in a vicious competition situation.
The size of the company is still small. The characteristics of domestic LED companies are: the number of companies is large and small, whether it is the extension of previous processes, chips, or the encapsulation and application products of post-processes, this is the structural form, even if it is the largest LED company in China, and Compared with overseas counterparts, their scale is still much smaller. By the end of 2011, LED companies in the upper and middle reaches of the country have not had a company whose main business income exceeds 1 billion yuan. This type of enterprise will lack R&D strength, low product quality, lack of competitiveness in the market, and development of China's LED industry. It is very unfavorable.
