摘要
针对现有植物光源系统架构难以提供优质的照明环境,提出空间照明均匀度理论。采用多光源模块的植物光源系统实现植物生长空间内的高空间照度均匀度以及色度均匀度,多光源模块由倒置光源、直下式光源以及在生长空间的中部光源组成。通过多光源模块的立体化混光方式达到设计的目的,根据Taguchi理论简化实验过程并结合变异数分析深入优化关键因子,从而找到植物光源系统的最优解。进一步优化LED灯珠的形状和间距,最终获得水平面和竖直面的照度均匀度分别为91.35%和89.71%,混色均匀度分别为87.67%和88.54%的立体化植物光源系统。对植物生长进行模拟和实物测试,实验结果表明植物光源系统能够在整个植物生长空间提供高质量的照明效果。
Abstract
Existing plant light source systems do not provide a sufficiently high-quality lighting environment for optimal plant growth, the theory of spatial illumination uniformity is proposed. The plant light source system with multiple light source modules is adopted to achieve high spatial illumination uniformity and color-mixed uniformity in the plant growth space. The multi-light source module is composed of inverted light source, straight down light source and central light source in the growth space. The experimental process is simplified according to the Taguchi theory and the key factors are optimized in conjunction with an analysis of varianceto find the optimal plant light source system. The shape and spacing of LED beads are further optimized to obtain a three-dimensional plant light source system with the illumination uniformity of horizontal and vertical planes of 91.35% and 89.71%, and color-mixed uniformity of 87.67% and 88.54%, respectively. Plant growth is simulated and tested in kind, the experimental results show that the three-dimensional plant light source system can provide high-quality lighting effects for the entire plant growth space.
