However  high cost is the main factor restricting widespread application of LED lighting  and the packaging is the most expensive aspect of LED products. Light emitting diodes (LED) are regarded as the most important light sources in solid-state lighting for their advantages in energy efficiency  long life  vivid colors  high reliability  environmental protection  safety and multiple applications. However  application of LEDs in projection display exist many questions such as low illuminance uniformity and low energy efficiency by reason of luminescence distribution and constructure specificity for LED  the study on application of LED in the micro-projection display and projection display is reported[2-8]. Considering the question mensioned above the rectangular CPC(Compound Parabolic Concentrator) system with three-color LED is applied in the projection display. 2009 SPIE.   An opinion search system for consumer products 会议论文  OAI收割 Proceedings of the International Joint Conference on Neural Networks, Hong Kong, China, 2008.6.1- 2008.6.6 作者:  Miao Qingliang;  Li Qiudan 收藏  |  浏览/下载：14/0  |  提交时间：2016/10/27 consumer products  opinion search
