Hangzhou accelerate the development of semiconductor lighting industry

Semiconductor light source is a cold light source photoelectric conversion rate high, power consumption is only 1/5-1/10 of incandescent lamp, life of up to 100 thousand hours, and the light source has the advantages of light high purity, safe use, free maintenance, no pollution, in promoting the green environmental protection, high efficiency and energy conservation today, has been vigorously spread all over the world. At present, the semiconductor lighting has begun to be applied to the city, landscape lighting and landscaping, is expected to soon replace incandescent, thus ending the Edison lighting era, the application prospects are very broad. According to expert analysis, gallium nitride (GaN) semiconductor light-emitting diodes (referred to as LED) will cause another technological revolution after the computer.

China currently occupy the world 60% lamps export market, Zhejiang province occupies export volume of 60%, become the core region of Chinese civilian lamp. If the development of semiconductor lighting to seize this historic opportunity to concentrate on the development of the third generation lighting, semiconductor lighting industry will become a pillar industry in Hangzhou and Zhejiang, on the other hand, missed opportunities for Zhejiang's economic impact is very heavy.

, an attractive market prospects

1 semiconductor white light lighting will help ease the power shortage in Hangzhou and Zhejiang province.

White LED and traditional lighting and display light source in comparison, there are many obvious advantages, and has very broad application prospects. The first is the energy saving and long life, the traditional incandescent bulbs are used in the heat emitting technology, it wastes 90% of the energy. The light emitting diode will give up to a hundred years of history of tungsten bulb era is over, its efficiency conversion rate is very high, greatly saving the electricity consumption. Ordinary light bulbs can only be used for 1000 hours, white LED lamp can be used for 100000 hours. Followed by environmental protection, due to the use of only 3 volts, and DC, no electromagnetic interference. And long life, resulting in less waste, unlike fluorescent light will produce mercury vapor and other pollutants. At the same time, the fluorescent powder is only 1/10 of the ordinary fluorescent lamp, which is beneficial to the sustainable utilization of rare earth resources.

2002 China lighting electricity accounted for about 1 trillion and 650 billion of China's total generating capacity of 12%, about 200 billion degrees, equivalent to 2 times more total generating capacity of the Three Gorges, lighting energy saving potential. If the use of "semiconductor light" to replace the traditional light source, according to energy saving 45%, can be less to build a Three Gorges power station, to a certain extent, alleviate the shortage of resources brought about by the national economic development.

2 third generation semiconductor technology and new products of blue LED come out, the rich Hangzhou city night scene.

2003 is Hangzhou city lighting project on the greatest efforts of the year, only in the West Lake area, in addition to Yang Gongdi, the new Lake area "shine", Sir Georg Solti, Bai Di, small Yingzhou, and on the east side of West Lake Pavilion and ruangong consists of 43 buildings of the city skyline at night "old look". Yanan Road, Hefangjie Street, Wulin Road, National Tourism Fair square, elevated river road and a few mouth Main Street Plaza is also covered with night dress. At present, Hangzhou has basically formed the West Lake city as the core, the urban landscape architecture composed of urban key building communities. The next 3-5 years, Hangzhou will continue to dressing night city landscape, by road lighting, architectural lighting, advertising light boxes and other city lighting elements of a feature rich Hangzhou city landscape lighting system construction. Most LED products are mainly red, yellow and green based. GaN new product of blue LED, not only enriched the LED family color, with red orange yellow green blue purple color, city nightscape lighting system more rich Hangzhou characteristics, and promote the development of the tourism economy in Hangzhou.

3 development of semiconductor lighting industry, bring huge economic benefits for Hangzhou

According to the forecast, the market scale of China's light will reach $27 billion so far this year. Annual growth rate of over 30%. It is estimated that by 2010, the world will have 1/2 of tungsten filament bulbs and all fluorescent lamps will be replaced by white LED. If the project is successfully implemented, it will be a huge change in the field of lighting, which is closely related to human life and production, will become one of the new economic growth point and breakthrough in Hangzhou. According to authoritative analysis, by 2006, Hangzhou LED industry will achieve sales of 15-20 billion yuan, 100 million U.S. dollars in foreign exchange earnings. By 2010, Hangzhou semiconductor lighting industry will achieve 100-120 billion yuan, 3-5 billion u.s.. Hangzhou will become China's LED and optoelectronics industry demonstration zone, the semiconductor industry technology innovation demonstration zone and industrial cluster.

Basis and advantages of two, Hangzhou

At present in the domestic semiconductor lighting industry development the main problems are: first, the number of packaging enterprises many, small-scale enterprises, have a certain strength of the company, the annual packaging capacity is only 200 million ~ 400 million. And only the annual packaging capacity of more than 1 billion per year, in order to participate in international market competition. Second, the current ultra high brightness LED chip mainly rely on imports, high-grade, better performance of the chip is difficult to buy. High power LED package just in the development stage, mainly due to the lack of high-power LED chips, it is difficult to break through the package. Third, for packaging white LED, the current performance of several phosphors to be improved as soon as possible.

LED lighting industry chain: raw materials - Equipment - substrate - epitaxial -LED chip + fluorescent material application. In the whole industry chain, the key technology is the preparation of GaN based epitaxial materials, large size chip manufacturing and packaging technology. Hangzhou is developing
