【摘要】：为了提高LED植物光源的有效利用率,基于Taguchi的实验方法对LED植物红蓝光源阵列进行设计和优化。用MATLAB软件编程进行仿真模拟,通过ANOVA方法分析得出对植物光源照射距离为10 cm处的红蓝光的光子数比值(R/B)分布均匀度影响最大的因子,并对试验最优结果采用Trace Pro光学软件进行试验验证,从而获得本次试验最佳的参数组合。结果表明:曲率半径为50 mm的凹形曲面底板的圆心加点排布方式,圆心为LED蓝光芯片,圆环上为LED红光芯片,芯片数量分别为6个LED红光芯片和1个LED蓝光芯片,芯片距离为10 mm的最优化组合是本次试验的最优组合。通过ANOVA方法分析得出,LED红蓝芯片之间的间距对植物光源的R/B的均匀分布影响最大,占有35.17%的比例,LED红蓝芯片的排布方式也不可忽略,因为其占有了28.05%的影响比例。
[Abstract]:In order to improve the effective utilization rate of LED plant light source, the experimental method based on Taguchi is used to design and optimize the LED plant red and blue light source array. By means of ANOVA analysis, the most important factor affecting the distribution uniformity of the red and blue light at a distance of 10 cm is obtained, and the optimum results are verified by Trace Pro optical software. The results show that the center of the bottom plate with a curvature radius of 50 mm is arranged at the center of LED blue chip, and the ring is a LED red chip. The number of chips is 6 LED red light chips and 1 LED blue light chip. The optimal combination of chips with a distance of 10 mm is the best combination in this experiment. The results of ANOVA analysis show that the distance between red and blue chips has the greatest effect on the uniform distribution of R / B of the plant light source. 35.17% of the LED red and blue chip layout can not be ignored, because it accounts for 28.05% of the impact of the proportion.
