可见光通信光源布局阴影效应光照度 visible light communication layout of lighting LED LED shadow effect illumination

摘要

在可见光通信系统中, 光源具有照明和通信的双重作用, 由于房间的大小以及室内环境各不相同, 难免会存在光照射不到或者光线比较微弱的地方, 这些地方很有可能成为通信的盲区, 这将会大大影响通信的质量, 为了解决阴影效应, 需合理对光源进行布局设计, 以4 m×4 m×3 m房间为模型, 采用四个LED列阵作为室内光源, 将单个的LED光源看做朗伯光源, 服从朗伯辐射模型, 通过公式计算结合软件仿真分析对比得出了采用9×9大小的LED列阵, 列阵距离屋顶边缘0.4 m, LED光源间的间距为0.03 m时, 在满足国际室内照明标准的前提下, 在距离屋顶2.25 m的4 m×4 m接收平面上光照度分布最均匀,其均匀度达到90.4%。该光源列阵布局模型可推广到任意尺寸房间, 为室内办公照明中光源的布局提供了一种可行的方案。

Abstract

In the visible light communication system, the light source has a double function of illumination and communication. As the size of the room and the indoor environment is different, it is inevitable that there will be somewhere with less light irradiation or the light is weak. These places are likely to become a communication blindzone, which will greatly affect the quality of the communication. In order to solve the shadow effect, a rational layout of the light source is needed. Based on 4 m×4 m×3 m room model, four LED array was adopted as indoor lighting. A single LED light source was considered as a lambert illuminant, which obeyed the Lamber tradiation model. Through formula and software simulation analysis, it was known that when the size of LED array was 9×9 and the distance from LED array to the edge of roof was 0.4 m and the spacing between the LED light source was 0.03 m, the illumination distribution was most uniform in the horizontal plane of 2.25 m from the roof on the premise of meeting the international standard of indoor lighting. And the uniformity of illumination is 90.4% in the 4 m×4 m receiving plane. The model of layout of light source array can be extended to any size of the room in this paper, which provides a feasible solution for the layout of the indoor office lighting source.
