摘　　要：为了提高LED植物生长光源的光照均匀性,提高光照强度,利用Tracepro光学仿真软件设计了红蓝白LED植物生长光源灯珠3种排布方式模型,对各排布方式分别设置了等间距排列和等差数列排列的组合方案,比较其均匀性及光照强度.仿真结果表明不同排布方式和各排列组合方案对辐射照度和均匀性有一定的影响,双线排布在SA40处理下的光源均匀性高于其他处理方式.为了验证仿真设计的可靠性,基于仿真最优结果(SA40双线)制作LED植物生长光源作为试验组,CK30单线排布光源及传统LED白灯作为对照组,搭建6条光源组合照明平台,在150 mm受光距离下测量3组光源均匀性.结果表明SA40处理下的红蓝白双线排布光源光照均匀性最好(88.93%),与仿真结果相符,说明其排布参数设计合理.In order to improve the illumination uniformity and intensity of the LED light source for plant growth,in this study,the three kinds of arrangement patterns of LED light source beads were designed by Tracepro optical simulation software.And the arrangement schemes of equal spacing and arithmetic progression were constructed,and the best lamp bead arrangements were presented by comparing with the uniformity and the light intensity of every scheme.The simulation results showed that the arrangement and combination schemes had a certain influence on the irradiance and uniformity,and the uniformity of the light source of the double-line arrangement with the SA40 was higher than other methods.In order to verify the reliability of the arrangement,a real experiment was setup based on the simulation optimal result(SA40 double-line),the light source of the single-line arrangement(CK30)and the traditional LED white light was used as the control group to build illumination platforms combined with 6 light sources.The uniformity of the three sets of light sources was measured at a distance of 150 mm.The experimental results showed that the illumination uniformity of the double-line arrangement of SA40 had a good performance with 88.93%uniformity that the arrangement parameters were reasonable.
