摘要

传统植物照明设计只优化某一参考面的均匀度,导致植物生长空间内的光环境不均一。为了解决该问题,对空间照明均匀度评价体系进行了研究。首先,提出了三种潜在的立体化高空间照明均匀度植物光源设计方案,并借助TracePro光学仿真软件研究了结构参数对照明效果的影响。进一步利用Taguchi方法优化实验过程,并结合ANOVA分析,获得了最佳方案的最优结构参数。然后,基于所得最优解,对植物生长过程中的照明效果进行了测试。最后,介绍了立体化光源系统相对传统阵列式LED光源的技术优势。实验结果表明:最优结构可提供一个均匀照明空间,该空间内的水平面照明均匀度和垂直面照明均匀度分别为92.00%和83.12%,并且两个空间参考平面上的红蓝光混色均匀度分别达到94.19%和90.70%。该植物光源系统可为植物提供其生长过程中所需的均匀空间照明环境。

Abstract

The traditional plant lighting design only optimizes the uniformity of a certain reference surface, which leads to the unevenness of the light environment in the plant growth space. In order to solve this problem, we conduct the research based on the spatial illunimation uniformity evaluation system. First, three potential design schemes are proposed for the stereo plant light sources with high spatial illumination uniformity, and the effect of structural parameters on illumination is studied with the help of the TracePro commercial simulation software. Further, the Taguchi method is used to optimize the experimental process and the optimal structural parameters are obtained with the ANOVA analysis. Then, the illumination effect during plant growth is tested based on the obtained optimal solution. Finally, the technical advantages of the stereo light source system compared with the traditional array LED light source are introduced. The experimental results show that the optimal structure can provide a uniform illumination space with illumination uniformity of horizontal planes and illumination uniformity of vertical planes of 92.00% and 83.12%, respectively, and with the red and blue color-mixed uniformity of two spatial reference planes of 94.19% and 90.70%, respectively. The plant light source system can meet the need of a uniform spatial illumination environment during plant growth.
