摘　　要：本文对可见光通信(VLC)系统的光源——商用大功率照明白光LED的调制特性进行了研究。通过对白光LED发光原理和商用照明白光LED的特性的分析进而得出可见光通信系统光源实验的最佳选择类型。分析了白光LED的调制特性,针对LED调制带宽特性专门设计了一个VLC系统作为实验平台,测量并比较了多种型号的商用大功率LED的调制性能得出实验数据和结论。通过对实验数据进行分析从而总结出目前商用照明白光LED的调制特性,为今后可见光通信系统的光源选择提供理论指导。This paper conducts a profound research on modulation features of commercial high-power white LED, the light source of Visible Light Communication (VLC). Through the white LED light commercial lighting principles and the analysis of the characteristics of white LED, Come visible light communication system the best choice for the type of ex-periment. Analysis of the modulation characteristics of white LED, LED modulation bandwidth characteristics for a VLC system is designed as an experimental platform. Measure and compare a variety of types of commercial high- power LED modulation performance of experimental data and conclusions drawn. Through the analysis of experimental data to conclude that the current commercial white LED lighting modulation characteristics. It provides theoretical guidance for visible light communication system to choose the light sources in the future.
