In 2009, China's chip output up 25% compared with 2008, reaching 2.3 billion; LED packaging production value of 204 million; semiconductor lighting applications in the impact from the financial crisis, the contrarian growth of more than 30%, reaching 60 billion yuan. In 2009 the total scale of China's LED industry, a total of 82.7 billion yuan!
2009 is the internal and external environment of China's semiconductor lighting industry, changes in the year. From the industrial environment, industrial environment at home and abroad affect the major events have occurred, the semiconductor lighting and in today's world of social and economic development linked closer to the opportunities and challenges; from industry itself, domestic and foreign technology continues to breakthroughs in new applications the rapid development of the gradual introduction of the relevant supporting policies, industry competition in technology, markets, products, etc. are all dimensions of the emergence of new patterns; from the industrial development trend, development opportunities for China's semiconductor lighting industry, significantly greater than the challenges, the overall industrial environment and industrial competitiveness further improved the prospects for industrial development clearer.
2009 is also the development of China's semiconductor lighting industry, volatile year. In the first quarter by the 2008 financial crisis led to the continuing impact of decline in exports, industrial development is slow, some business difficulties and even collapse. From the second quarter, as China's "10 City, 10000," application demonstration project to promote the improvement of domestic and international market conditions, the semiconductor lighting industries have begun to stabilize and rebound, becoming the first out of the crisis-affected industries. In the second half, China's semiconductor lighting industry, the situation continued to improve, in the energy-saving and low-carbon emission reduction under the impetus of economic concepts, the semiconductor light started to become a hot industry.
In 2009, under the impact of rapid increase in chip demand, China's rapid increase in production capacity epitaxial silicon. According to statistics, the domestic enterprises engaged in production of LED chip, more than 40 enterprises of the MOCVD has more than 150 of which have been installed-type GaN MOCVD production of more than 135 sets of production quaternary MOCVD 18 computers a month, domestic scientific research institutes Research facilities also increased. The company plans to further accelerate the extension of chip investments, according to preliminary statistics, the planned device in 100 or so, the development of much more than expected in early 2009.
In 2009, China's chip output increased 25% to 2.3 billion in 2008 to 26% of the growth was essentially flat. GaN chip in 2009 made a very prominent increase in production capacity, compared with 2008 growth of 60%, reaching 2.24 billion / month, while the actual annual increase of 40% to 18.2 billion, domestic rates increase to 46%. A larger domestic performance chips increase, in the display, lights, outdoor lighting, small and medium size high-end applications such as backlighting recognized, high-power chip, performance and output has also been improved so much. In 2009, with the gradual weakening impact of the financial crisis and the rapid improvement in business conditions, the domestic chip companies in 2009 obtained a better business environment, the next few years, the domestic chip production and business operating conditions will remain an rapid enhancement of the process.
In 2009, China's LED packaging production value reached 20.4 billion yuan more than in 2008 18.5 billion an increase of 10%; production from 2008 to 94 billion an increase of 10% to 105.6 billion, of which highlight the LED output value reached 18.6 billion , accounting for 90% of total sales LED. At the same time from product and enterprise structure has greatly improved the domestic terms, SMD, and high-power LED packages faster growth.
In 2009, China's semiconductor lighting applications in the effect from the financial crisis has made rapid growth, more than 30% overall growth, the output value reached 60 billion yuan. LED full-color display, solar LED, landscape lighting, consumer electronics, backlighting, signals, instructions, etc., as the main application areas, an increase of more steady.
Accelerate the application of LED-TV in the context of large-size LED backlight applications in China has made important progress, major TV brands have launched a LED backlight TV, and as the focus of the next few years to develop and promote their products. In China's "10 City, 10000," demonstration project, led, LED lights and other road lighting, LED lighting and other interior lighting applications developed rapidly. LCD backlight and lighting in 2009, the growth has been China's semiconductor lighting is gradually becoming the main fields of application.
In terms of investment, domestic large enterprises and the capital began to aggressively intervene in semiconductor lighting industry, industrial investment has obviously increased. According to public statistics, in 2009 throughout the country LED total investment amount (including plans for investment) has more than 20 billion yuan, a number of listed companies through acquisitions or raise capital investment into the field of semiconductor lighting, there are a number of solid-state lighting companies preparing for listing to raise funds for expansion.
On the technical side, the domestic production of low-power chips has been achieved 120lm / W, Power-based chip, 80-100lm / W, with the level of international industry closer together. China's own intellectual property rights Si substrate chip optical power efficiency of 70lm / W, and to achieve economies of scale production. China's high-power package, the level of world-class basic synchronization, in a small species, multi-volume production capacity at the international advanced level, such as the miner's lamp, landscape lamp and other special needs of the LED packages.
Is expected in 2010, both from the applications and promotion, technology level, capital operation, or business areas will have some new changes.
In the applications, growth will be mainly reflected in the lighting and LCD backlighting applications, in other areas of development will be more steady. With the price of semiconductor lighting products and application of the rapid decline in technology continues to mature, domestic and international semiconductor lighting at the municipal, domestic, commercial and industrial areas such as the promotion of the various areas of expertise will accelerate the application, and our party in the product manufacturing has the more obvious advantages of LED lighting products is expected to become the manufacturing center, while the manufacturing model will be OEM, ODM and own-brand production and marketing of various forms of expression;
Although LED backlight module industry in China is still relatively backward, but the LCD panel industry is gradually transferred to China, China is likely to become the world's largest LCD TV production base machine, with simultaneous production of LCD TVs machine, LED backlight modules, the production of parts after the process will also focus on China, the domestic production prospects for the development great.
On the technical side, our sapphire substrate GaN-based chips and white patent technology constraints still exist, with the production capacity of Chinese enterprises, technology level and international manufacturers to speed up the layout of domestic production, domestic enterprises will place more directly with international manufacturers competition. This also means that international companies will inevitably use of patented a way to bolster their competitive edge, relevant domestic enterprises should take precautions ahead of the competition in the layout of the patent. In 2010 and beyond, large foreign companies in China will gradually open up the patent license is expected early in the application of product patent cross licensing deal will be part of financial gain the main part of the chip and the device will be more to patent litigation against competitors, mainly to obtain a competitive advantage.
With regard to enterprises with R & D, capital, markets, manufacturing, and other advantages of the company is expected to rapidly expand the scale of related industries, industry concentration degree will be improved. By the 2009 operating results of semiconductor lighting capital, inspired by, more companies will be listed or plan to introduce strategic investors, the competitive level of product technology will be more to the capital, and market level shift, which will cause the industry pattern of related adjustments.
From the industry as a whole, such adjustments will help domestic enterprises to enter the backlighting, automotive, lighting and other more complex areas of competition and gain advantage. Competition in the enterprise, government-related measures will also be a crucial factor in government at all levels is expected in 2009 will focus on the macro-guidance from the 2009 project were implemented to a greater emphasis on practical measures.
