The first white LED production line put into operation

China's first batch of more than 60 lumens per watt (luminous efficiency units, the greater its value indicates that the higher luminous efficiency of white light emitting diode) chip production line, 28 in the Tsinghua Science Park Electronic Co. Ltd started production.

According to Tsinghua Science and Technology Park Technology Co., Ltd. Yi Hanping, director of introduction, as a new semiconductor light source, LED (light emitting diode) is reflected in three aspects: energy saving, environmental protection and long life. LED energy consumption is 10% of incandescent lamp, fluorescent lamp is 50%. LED solid package, solid structure, life of up to 100 thousand hours, is a fluorescent lamp 10 times, incandescent lamp of 100 times. In environmental protection, the use of LED instead of incandescent or fluorescent lamps, without the use of glass vacuum packaging, no toxic gas and mercury pollution.

As a new semiconductor light source, semiconductor lighting has become a sunrise industry in twenty-first Century. According to statistics, in 2003 Chinese LED chip market sales of 6 billion 100 million, to 2006 Chinese high brightness LED chip market sales as high as 15 billion 400 million, while in 2006 the global high brightness LED chip market sales will be as high as 108 billion 500 million.

According to reports, China's LED industry has initially formed a production, from wafer and chip manufacturing, packaging to the integrated application of relatively complete industrial chain, but a very large gap in the upstream of LED, mainly MOCVD (metal chemical vapor deposition equipment) epitaxial material level is not high, not large scale, inadequate investment, lack of talent.

It is understood that the ultra high brightness LED industrialization project led by the Hebei Institute of Tsinghua development, cooperation with foreign advanced LED research institutions. According to the measured results of domestic testing organizations, white LED Tsinghua Science Park Electronic Co. Ltd production average luminous efficiency has reached 59 lumens per watt, far higher than the current level, reached the advanced level in the world. High brightness LED light source products developed can be widely used in city landscape lighting, road and traffic signs, indoor and outdoor decorative lighting, full-color display, car lights, mobile phone and digital camera and flash based on field.

Yi Hanping said that their goal is to absorb the international advanced level in the digestion, to establish their own high brightness LED R & D center, development of independent intellectual property rights of technology and products, breakthroughs in key technologies, the formation of high brightness LED relatively complete industrial chain of R & D and production base. To the end of 2008 at the end of the third phase of the project, in addition to reach an annual output of blue LED epitaxial wafers 180 thousand, 2 billion 400 million chip grain size, will be built with an annual output of 500 million high power LED package of scientific research and production base, the breakthrough and the formation of semiconductor lighting industrial supporting technology.
