In this paper the indoor visible light communication (VLC) multipath channel model is analyzed. A new reflection model based on the Lambert-Phong pattern is presented by investigation of the reflection characteristics. Through the MonteCarlo ray tracing simulation based on the Lambert-Phong pattern, the VLC optical channel models are set up, including the single source and multiple-source systems. The simulation results show that using the Lambert-Phong reflection pattern, the calculation becomes linear to the number of reflections and the computation complexity is decreased.
