摘　　要：LED照明具有节能、可靠、使用寿命长等特点,被认为是下一代主流照明技术。基于LED比荧光灯和白炽灯切换速度快的特性,用室内照明的白光LED光源作为通信基站进行信息无线传输的技术,就是现在国内外研究的热点技术-可见光通信技术。文章简要介绍了白光LED可见光无线通信技术在的研究现状,分析了它的关键技术,并从应用角度出发阐述了LED可见光无线通信技术的发展趋势。LED lighting with energy- saving, reliable, long life and other characteristics, is considered the next generation of main- stream lighting technology. LED- based fluorescent lamps and incandescent than fast switching characteristics, with the interior lighting of the white LED light source of information as a communication base station wireless transmission technology, international research is now the hot technology - visible light communication technology. This paper briefly describes the white LED visi- ble- light wireless communication technology in the study abroad status, analysis of its key technologies, and from the application point of view expounded LED visible light, wireless communication technology trends.
