Analyses the LED application present situation and development prospects
Abstract: LED is today a set of environmental protection, energy saving, life waiting advantages of a high-tech green technology products, in line with the strategic objectives of national sustainable development, the introduction of its enormous impact on the development of today's technology. Through the background of LED technology, the basic theory of technology infrastructure and technology are introduced, the status of the application of LED technology, conduct research, and on the basis of existing technologies and on the development prospects of the conditions LED analyzed. Today's situation, the development of LED industry by high costs, publicity is not in place, the impact of poor public awareness of environmental protection and many other reasons are not so smooth. Therefore, for countries and companies, the need to greatly increase awareness of independent innovation, accelerate the pace of technological innovation, reduce costs, widely publicized LED lighting, making it popular as soon as possible, and truly benefit all consumers.

浅析LED的应用现状与发展前景 引言
LED身为一种新兴的技术和光源，集寿命长，绿色环保，节省能源，抗震性强和不包含铅、汞等诸多优点于一身。完善的LED产业链，包含上游的芯片和外延片的制造，中游的零件封装和下游的产品的应用[1]。其产业链规模巨大，在很多产业领域都有应用。文章主要是对LED的应用现状和发展前景做分析和总结，着重对LED下游应用的发展现状和照明应用做重点的介绍，进而对LED的发展前景做简单介绍。文章选取LED照明的应用做重点介绍的原因是LED照明从产品的研发和产品的使用都涉及了很多的领域，从专一的照明应用的领域，可从应用的角度折射出整个LED行业的发展趋势，对LED产业链的下中上游的应用都可以有所提及。为了实现论文要达到的预期效果，文章第一部分对LED的产生背景和技术方面做宏观环境介绍，进而引出LED照明的设计理论和LED和发光原理；第二部分阐述LED的相关特性和技术方面的优缺点，从而让大家了解到LED产业具有很大的发展潜力的同时也遇到很多的技术问题，它的发展并不是一帆风顺的；第三部分将介绍LED的应用现状和应用领域，重点还是对LED照明做重点介绍，通过对LED最近几年的发展做分析折射出发展现状；论文最后一部分则是对LED产业的的发展做一些简单规划和畅想并提供一些有助于发展的意见。
