The development history of LED lighting in china"

Over the past ten years, in the face of the huge business opportunities and encouraging development prospects of the LED industry, the various countries around the world have launched a fierce competition in the development of LED. The United States since 2000 to invest $500 million to implement the national semiconductor lighting plan, the EU announced in July 2000 to launch a similar rainbow project". South Korea GaN semiconductor development plan from 2000 to 2008, the government invested $472 million, the company invested $736 million. China's Ministry of science and technology under the support of the "863" plan, in 2003, June first proposed the development of semiconductor lighting program. A series of data show that as early as ten years ago, semiconductor lighting has successfully attracted attention of governments, and secretly hard competition, and the emergence of LED, also known as "the third lighting revolution history".

At night LED lighting in China

Since June 17, 2003, China's Ministry of science and technology led the establishment of cross sectoral, cross regional, cross industry "national semiconductor lighting project coordination leading group", to 2005, emergency start of semiconductor lighting industry in the "fifteen" project in the key technology of major projects, to 2006, in the "11th Five-Year" start, the national semiconductor lighting project as a major project to promote. As of 2006, the Ministry of science and technology successfully approved Shanghai, Dalian, Nanchang, Xiamen and Shenzhen as an industrial base, which is more rapid development in the region of Shenzhen.

Chinese LED industrial development since 2003, including extension, chip, package, the application of products on the downstream industry chain, "Shen" state gradually changed, China upstream of the LED industry has been rapid development, one of the most striking chip industry development. Nevertheless, the core patent LED lighting technology is basically a few big foreign companies control, such as Japan's Nichia, TOYOTA, Toshiba, the United States Philips synthesis of Lumileds, Cree, Osram in Germany, these companies use their own core patent, take horizontal and vertical expansion, layout strict patent net in the world also, the subsequent development of China enterprise patent crisis.

From the point of view of the history of the development of white LED, white LED from its inception in 1997, LED lighting technology is in a stage of rapid development, and continuously improve the luminous efficiency, in 2005, the industry is almost universally predicted commercially available white LED to achieve the luminous efficiency of 100lm/W is the earliest to wait until 2007 or 2008, the luminous efficiency of 100lm/W is better than CITIZEN the electronic development blueprint for a year early, which not only because the technology of open market competition, including factors of coping price collapse.

The patent trap, with technology is not mature, the cost is high, so at that time (2003 to 2007) just broke into the LED industry enterprises suffered all kinds of suffering, "while Luo Wenzheng is the only feeling at the time, so Sony light engineer said to reporters," LED industry market in what time to heat up? In the outbreak? When the industry "is one of the most popular topics discussed. At that time a lot of companies, it seems to smell the potential business opportunities LED lighting, LED lighting with a bright future in the future, swarm began to invest heavily. But when LED lighting technology is not mature, the cost is too expensive, the market unfamiliar to LED products, although many manufacturers have introduced a variety of products, but praised, this is a great test of the LED lighting industry. Many companies are difficult to support R & D and market development of high input and low returns, sadly out of the market.

The exploration of LED lighting in the dark night in our country

Vigorously promote energy-saving emission reduction in the world, and actively respond to climate change in the situation, in 11th Five-Year, China proposed a 20% reduction in energy consumption per unit of GDP, the main pollutant emissions to reduce the binding target of 10%. At the same time, many countries have introduced the elimination of incandescent roadmap, then, China has gradually accelerated the elimination of inefficient lighting products. As of November 2011, China has established a relatively complete elimination of high energy consuming products and energy-saving product promotion policy system, including the release of high energy consuming products out of the directory, the implementation of energy efficiency standards, the implementation of mandatory government procurement, identification of government financial subsidies and other measures.

October 2011, the national development and Reform Commission issued a formal announcement of the Chinese government to eliminate incandescent lamps and roadmap, and from October 1, 2011 to September 30, 2012 as a transitional period. According to the road map, by 2016, will be a total ban on the sale of a variety of incandescent incandescent lamps. From 2011 to 2016, incandescent lamp has the transition time of 5 years, set aside a large buffer for manufacturers, distributors and consumers; and the command will lead manufacturers to stop production, distributors to stop sales, its market share will naturally decline, which will undoubtedly provide a huge market opportunity to promote and popularize the application of my LED country.

Although the national policy gives LED the opportunity to enter the market, but in 2010 ~2011 did not usher in the outbreak, the industry predicted instead, processing of energy-saving lamps, the enterprise market listing scam fishing gold, patent infringement and other negative news is full of the LED lighting industry, more shocking is that in October 8, 2010, has been rated "Shenzhen China industry (Optoelectronics) chairman of the Shenzhen junduoli Industrial Company Mao Guojun and top 10 enterprises" as relatives of missing, suddenly disappeared. In October of the same year, there are more news Shenzhen up to 80 LED companies closed down, the LED industry was suddenly a burst of business owners foot tide masking. MOCVD blind introduction led to overcapacity, lack of nuclear
