针对智慧珞灯及车联网的应用需求，设计了基于可见光发光二极管（LED）珞灯的通信模型。首先，提出 LED羊珞稳定和多珞稳定的照度预均衡方法，并测试了预均衡接收效果。其次，根据羊侧、双侧对称和双 侧非对称等珞灯安装方式，用朗伯特模型构造和仿真了 3种珞灯的空间照度分布数学模型，分析了道珞近地区域的平均照度。最后，据此设计了可见光信号的车辆接收模型和 LED珞灯到车辆的色分多珞复用（CDM）可 见光通信模型，并分析了模型的信号接收波形和该模型的多径效应。

Aim to the application of smart street lamp and internet of vehicles, a communication model of street lamp based on visible light-emitting diode （LED) is designed. Firstly, the illumination pre-equalization method of LED single channel stability and multi-channel stability is proposed, and the receiving effect is tested. Secondly, according to the installation methods of uni-lateral, bilateral symmetrical and bilateral asymmetric street lamps, the spatial illumination distribution mathematical models of three kinds of street lamps are constructed and simulated by Lambert model, and the average illumination in the near ground are a of the road is analyzed. Finally, the vehicle receiving model of visible light signal and the color division multiplexing (CDM) visi-ble light communication model from LED street lamp to vehicle are designed, and the signal receiving waveform of the model and the multipath effect of the model are analyzed.
