为一般照明前言，更需要白色的光源。在1998年发表的白光LED的研制成功。白光LED发光效率是逐步完善和设备的商业化已达到白炽灯的水平，实验室白光LED发光接近荧光灯的效率水平，稳定发展。它也已成为造成的污染，无长寿命，抗震动和冲击的显着特点，有LED白光LED产业，在全球能源短缺最有前途的新产品的担忧再次升高的背景下，白光LED照明被世界在欧洲，美国，日本等先进国家的关注，市场前景也投入大量的人力，并成立专门机构，以促进研究和白光LED的发展。这将是21世纪的新一代光源—第四代电源取代，如传统的光源，白炽灯，荧光灯和高压气体放电灯，白光LED有巨大的商业机会怀孕。自从50多年前的出现，LED发光二极管，但一直一直在努力实现固体光源的追求，首先从1960年的LED商业化引起的。英国

发光二极管发光二极管(LED)的首字母缩写的光，发光二极管LED制造技术的进步和新材料(氮化物晶体和荧光粉)的开发与应用，使发光的二极管的信号显示，已逐渐成为照明源，从单色(光的品种单一颜色)为白色，脂肪，白光LED半导体稳定的性能和持续改进光源进入实用阶段。出现的白色光的LED，高亮度LED应用进入了高效率的光源市场。一旦有人指出，高亮度LED将是人类在以下爱迪xx明白炽灯泡，最伟大的发明之一。随着LED的亮度逐年提高，在过去，只能用在室内的各种显示功能，并逐步扩大到室外的各种应用。过去很多只能使用一次灯泡，多光源的选择机会。

，LED单色显示器仍然占主导地位的申请，尽管其中许多有效地取代LED灯泡的使用，例如，发光二极管，如手机和数码相机闪光灯，汽车尾灯，刹车灯，交通灯，甚至是共同的近年来，地埋灯，或如景观照明工程应用中，应用的主要类型仍然是一个节目，而不是普通照明。目前，该LED的实际应用范围仍xx于所谓的特种照明，普通照明应用的有很大差距，其原因其实是白光LED的效率和提高价格过于缓慢，是需要各国政府的投入，大力支持严重，以加快研究和发展的步伐。好消息是，许多国家，政府已成立了一个国家计划，在研发生产综合实力，投资巨大的资金，这将有希望加快相关技术的开发以使下一代照明，尽快，日本，美国，韩国和中国的实际使用，已推出了{gjj}白光LED计划。中国的LED将有利于促进国家一级耗时15至20年，三峡电厂和相同，三峡电厂花费50％的建设资金，但大陆将30％的效率节余照明用电，一个长江三峡电厂发电量相当于。在短期，中期和长期计划，长期投资，为“中国国家半导体照明工程计划，最近的一个名字，”两年(2003年-2005在全国12 000万美元的资金);年中期规划将实施在十分之一的国家五年计划(2006 -2010)，以一两链为主体(研发+行业)平台，产业研究和发展目标为100 lmPW，研究所120 lmPW，为0.05袁萍流明市场价格的目标;长期来看，该国计划于固体照明战略将是前投入服务为5000000000?2020年拨款100亿人民币的研发目标为160? 200lmPW的袁萍为0.015流明市场价格的目标。 1，原则和LED的结构是半导体技术的电灯就20世纪之后出现的，50年代后，半导体技术的发展，并逐步在由Ⅲ - Ⅴ族化合物半导体发展。 LED发光原理是在一个半导体电子和空穴结合使用发出光子与传统的电阻加热使用，LED灯泡或荧光灯管排放是根本不同的… … 06.9.8

White LED lighting technology and industrial progress, and the market situation

Abstract: The semiconductor lighting of this century are the most promising high-tech area, the white LED will be the 21st century a new generation of light source — the fourth generation of electric light source can replace the incandescent, fluorescent and high-pressure gas discharge lamp, such as traditional light source, white LED pregnant with enormous business opportunities. The LED on the basic principles, characteristics and prospects for the development and application, and introduce white LED market and industry status quo.

Keywords: white LED; semiconductor lighting; light-emitting diodes; solid light source;

the foreword for the general lighting, it is more white light sources required. Issued in 1998 the successful development of white LED. White LED light-emitting efficiency is gradually improve and commercialization of the device has reached the level of incandescent, laboratory white LED light-emitting fluorescent lamp close to the level of efficiency and steady growth of. It also has as a result of pollution-free, long-life, anti-vibration and impact of the distinct characteristics, there are LED white LED industry, the most promising new products in the global energy shortage worries again elevated background, white LED lighting market prospects of being the world’s attention in Europe, America and Japan and other advanced countries have also invested in many human, and to set up specialized institutions to promote research and development of white LED. It will be the 21st century a new generation of light source — the fourth-generation power source to replace incandescent, fluorescent and high-pressure gas discharge lamp, such as traditional light source, white LED pregnant with enormous business opportunities. Since the emergence of more than 50 years ago, LED light-emitting diodes, there has been has been working to realize the pursuit of solid light source, the first arising from the commercialization of LED in 1960. English

LED are light emitting diode (LED)acronym, with the light-emitting diode LED manufacturing technology advances and new materials (crystal and nitride phosphors)Development and Application, making light-emitting diodes from the signal show has gradually become a lighting source, from the monochromatic (single color of light variety)to white; fat white LED light source of semiconductor solid performance and continuous improvement into the practical stage. The emergence of white-light LED, so that high-brightness LED applications enter the market of highly efficient light source. Once it was pointed out that high-brightness LED will be following are human after Edison invented incandescent bulbs, one of the greatest inventions. With LED brightness improve year by year, in the past can only be used in a variety of interior display function, and gradually expanded to a variety of outdoor applications. Many of the past can only use light bulbs of the occasion, more than a choice of light source opportunities.

On the whole, LED monochrome display applications still dominated, although many of them to effectively replace the use of LED light bulb example, such as mobile phones and digital camera LED flash, automotive taillights, brake lights, traffic lights and even common in recent years, buried lights or construction applications such as landscape lighting, however, the main types of applications are still a show rather than the general lighting. At present, the scope of the practical application of LED is still limited to the so-called special lighting, general lighting applications from there is quite a gap, The reason, in fact, are white LED efficiency and price improvement is too slow, it is badly in need of inputs from Governments to vigorously support in order to accelerate the pace of research and development. The good news is that many countries, the Government has set up a national plan, combined with production of the R & D strength, invest huge sums of money, which would have hoped to accelerate the development of related technologies to enable the next generation of lighting to practical use as soon as possible, Japan, the United States, South Korea and China have introduced a state-level white LED plan. China’s LED is expected to promote national-level time-consuming 15 to 20 years, the Three Gorges power plant and the same, the Three Gorges power plant to spend 5% of construction funds, but the mainland is expected to efficiency savings of 30% of lighting electricity, the equivalent of a Yangtze River Three Gorges electricity plant generating capacity. The plan at short, medium and long-term investment, the recent name of the scheme for the “China National Semiconductor Lighting Project,” a period of two years (2003 -2005)in funding for the National 12 000 million; medium-term planning will be implemented in one tenth of the country five-year plan (2006 -2010)to a platform for the two-chain (R & D + industry)as the mainstay, industry research and development objectives for the 100 lmPW, Institute for 120 lmPW, the market price target of 0.05 yuan P lumens; Long-term, the country is scheduled to solid lighting strategy will be put into operation before the 2020 funding for five billion ~ 10 billion yuan in R & D goals for the 160 ~ 200lmPW, the market price target of 0.015 yuan P lumens. 1, principles and structure of LED is a semiconductor technology made by the electric light comes on the heels of the 20th century, the 50s, after the development of semiconductor technology, and gradually by the of Ⅲ - Ⅴ compound semiconductor evolved. LED light-emitting principle is the use of semiconductors in a combination of electron and hole issued photon, with the traditional use of resistance heating LED light bulb or fluorescent tube discharge are fundamentally different … … (06-9-8)
