White LED Modulation Bandwidth and Modulation
Characteristics of the Study
Abstract: 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.
