摘　　要：传统的植物照明设计只针对单一参考面均匀度进行评价,难以满足植物在整个生长过程中对均匀光照环境的需求。针对这一问题,首先提出了空间照明均匀度评价体系,并基于该体系设计了一种复合光源模块的立体化照明系统,以期构建照明均匀的植物生长空间。进一步利用Taguchi方法优化实验过程,在结合ANOVA分析的基础上,获得了最优结构参数。最后对所得最优解进行灯珠形状分析和植物生长过程中的照明效果测试。实验结果表明:最优结构可提供一个水平参考面照度均匀度为87.22%,混色均匀度为90.11%;竖直参考面照度均匀度93.02%,混色均匀度91.43%的均匀照明空间。该植物光源系统可满足植物生长过程中对均匀空间照明环境的需求。The traditional plant lighting design only evaluates the uniformity of a single reference surface,and it is difficult to meet the light intensity and light quality requirements of different stages of plant growth.Aiming at this problem,first,a space lighting uniformity evaluation system was proposed,and based on this system,a threedimensional lighting system with a composite light source module was proposed,in order to construct a plant lighting space with uniform lighting.Further,the Taguchi method was used to optimize the experimental process,and the optimal structural parameters were obtained on the basis of ANOVA analysis.Finally,the lamp beads shape analysis and the lighting effect test during the plant growth process were performed on the obtained optimal solution.The experimental results show that the optimal structure can provide a uniform illumination space with horizontal reference plane illumination uniformity of 87.22%,color mixing uniformity of 90.11%;vertical reference plane illumination uniformity of 93.02%,and color mixing uniformity of 91.43%.The plant light source system can meet the requirement of a uniform space lighting environment during plant growth.
