摘　　要：在互联网通信高速发展的今天,人们对数据信息传输的速率和质量的有了愈来愈高的需求。但是,在目前的射频通信领域中,人们对数据传输的需求日益增加,这使得原本有限的频谱资源更加短缺。Li-Fi技术,具有可用频带宽、通信储量大、传输效率高以及能耗低等特点,得到通信领域的广泛关注。本文从Li-Fi技术的发展历程出发,对文中涉及到的Li-Fi基本概念做了界定,进而分析了Li-Fi的工作原理,接着介绍了Li-Fi的特点及应用,为随后的研究奠定了基础,然后通过对国内外Li-Fi技术发展现状的分析,引出了对Li-Fi技术发展前景的展望。Along with the rapid development of Internet technology, people have a higher request for data information transmission rate and quality. However, the increasing data transmission demand makes spectrum resources shortage more limited in the field of radio frequency communication today. Li-Fi technology has the available bandwidth, communications, large reserves, high transmission efficiency and low energy consumption advantages, get a lot of attention in the communications field. This article, starting from the development course of Li-Fi technology, defines basic concepts, and then analyzes the working principle, then introduces the characteristics and application, lays the foundation for the subsequent research, and then raises the prospect of Li - Fi technology development prospects through the analysis of the current situation of the development of the Li-Fi technology at home and abroad.
