GaN基白色发光二极管（LED）增加了实现用于植物生长的理想光谱的可能性。同时，在室内人工照明植物工厂中，白色LED的高光合作用对于植物照明以提高作物产量是非常关键的。本文通过设计一个基于通用遗传算法的非线性规划（NLP），对实现多基色白色LED高光效的光谱进行了综合优化（从三原色到五原色）在三种不同的相关色温下（CCT，分别为2700 K、4500 K和6500 K），同时测量显色性能，例如国际照明委员会（CIE）显色指数（CRI，Ra），两个特殊显色指数（R9和R12）和北美照明工程学会（IES）TM-30（Rf和Rg），以及颜色质量等级（CQS，Qa）。此外，这些提到的性能之间的比较不同的初级数量，CCT，和光谱带宽的多基色LED。最后，我们相信本文所获得的相关结果可以为室内农业实现高光合和优良色性能照明提供有益的指导。
The GaN-based white light-emitting diodes (LEDs) increase the possibility of realizing an ideal spectrum for the growth of plants. At the same time, high photosynthetic action of white LEDs is very crucial for the plant lighting to increase the crops productivity in the indoor artificial lighting plant factory. In this paper, via designing a non-linear program (NLP) based on the common genetic algorithm (GA), we are capable of conducting the comprehensive spectral optimization for realizing high photosynthetic action of multi-primary white LEDs (from three-primary to five-primary) under three different correlated color temperatures (CCTs, 2700 K, 4500 K, and 6500 K, respectively) while taking the color rendering performances, such as Commission Internationale de l'Eclairage (CIE) color rendering index (CRI, Ra), two special color rendering indices (R9 and R12) and Illuminating Engineering Society of North America (IES) TM-30 (Rf and Rg), and color quality scale (CQS, Qa) into account. In addition, these mentioned performances are compared among different primary numbers, CCTs, and spectral bandwidths in the multi-primary LEDs. Finally, we believe that the obtained relevant results presented here could provide a useful guidance for the achievement of high photosynthetic and excellent color performance lighting for the indoor farming.
