Semiconductor illume causes illume domain the 3rd times the century on revolution 90 time end, the breakthrough of technology of GaN of material of the 3rd acting semiconductor caused the 3rd revolution of illume domain, its indicate is to be based on semiconductor glow diode (LED) solid state illume (also say ” semiconductor lamp ” ) , will replace incandescent lamp and fluorescent lamp to LED spotlight common illume field stage by stage. Semiconductor illume uses semiconductor chip to regard glow as material, photoelectricity changeover efficiency is taller, have energy-saving, environmental protection, life to grow wait for an advantage, OK at indicating the many domains such as illuminant of illume, adornment illume, back, common illume applying. World each country takes seriously advance LED to develop strategic world each country to value semiconductor illume property. For example, basically advance a branch what the United States develops as semiconductor industry with energy department, formulate a series of the development of plan and industry of illume of policy support semiconductor. Below the joint efforts of each country government and enterprise, development of global LED technology is rapid, light produced by electricity changes efficiency to rise ceaselessly. Tall brightness LED regards LED technology as the prospective direction of development, be close to stage by stage practical. Global LED industry grows property of global semiconductor illume steadily growth is rapid, dimensions of market of global glow diode amounted to 5.73 billion dollar 2005. 2001 2006, the LED application market besides the mobile phone year average growth rate is about 22% . At present global LED industry formed the United States, inferior, the pattern of Ou San sufficient tripartite balance of forces. Day, beautiful technology is relatively banner, europe has relative advantage in what use a field. Area of our country Taiwan and Korea LED industry rise quickly in recent years. Development of estate of our country LED is rapid, industrial catenary forms our country already basically to take semiconductor illume seriously to develop the strategy. Green illume project already was labelled ” 915 ” 10 big focal points of countrywide are energy-saving one of projects. Ministry of science and technology was initiated ” project of national semiconductor illume ” . In recent years, rate of development of estate of our country LED is rapid at the whole world average level. Among them, technical content encloses course of study inferiorly development is rapidder, had had certain dimensions. Current, catenary of industry of our country LED is delayed outwards stage by stage piece wait for technical content and additional cost with chip production taller upriver domain is outspread, on, catenary of medium, downstream industry is formed already basically. In the meantime, gao Liang spends the proportion that LED is produced in our country LED and uses to be increased stage by stage. On the whole, technology of our country LED and abroad are put in bigger difference, need answers a series of questions such as patent block. Group of industry of our country LED is initial form our country preliminary formed triangle of delta of Pearl River delta, the Yangtse River, Fujian, Beijing and Dalian to wait for northern region area of industry of 4 big LED. Be in at the same time ” project of national semiconductor illume ” drive below, built the national semiconductor gaffer such as Shanghai, Dalian, Nanchang, Xiamen and Shenzhen Cheng industrialization base. With Dalian Lu Ming, Xiamen 3 how, Jiangxi couplet achieves photoelectricity, Shenzhen the LED company that Lan Mingxin of La Guang of Fang Daguo division, Shanghai, Hangzhou person is a delegate grows quickly.
