摘要

目前植物工厂培养架所使用的LED光源模块光学结构简单，照度均匀度和混色均匀度难以保证，导致农作物的品质参差不齐。为了提高种植物品质，需要优化植物光源的照明效果，设计高均匀度的植物光源。本文针对这一问题提出并研究了一种倒置光源的植物培养架设计方案。将LED灯珠安置在种植面同侧，并结合曲面反射顶面对LED发出的光线进行进一步均匀分配，在植物培养架有限的种植空间内增加光线耦合距离和耦合程度，提高了培养架植物光源的均匀度。经过多次结构优化后，最终获得了一个照度均匀度为91.64%、混色均匀度为89.73%的高均匀度植物照明培养架。然后基于优化得出的植物光源，研究植物生长过程对照明效果的影响后表明植物在生长过程中均可获得良好的照明环境。最后研究了不同形状和不同配光曲线的灯珠对培养架均匀度和光能利用率的影响。

Abstract

At present

the LED light source module used in the plant factory growing shelf has simple optical structure

so the illumination uniformity and color-mixed uniformity are difficult to ensure

which lead to uneven quality of crops. In order to improve the quality of the plant

it is necessary to optimize the illumination effect of the plant light source

and design a high uniformity plant light source. To this problem

this essay proposes and studies a design scheme of the plant growing shelf with inverted light source. The LED lamp bead is placed on the same side of the planting surface

and the light emitted by the LED is further uniformly distributed in combination with the curved reflecting top. This method increases the coupling distance and coupling degree of the light in the limited planting space of the plant growing shelf

thereby improving the uniformity of the plant light source. After several structural optimizations

a plant lighting growing shelf is obtained

whose illumination uniformity is 91.64% and color-mixed uniformity is 89.73% finally. Based on the plant light source

studying the influence of plant growth process on the lighting effect shows that the plant can obtain a good lighting environment during the growth process. At last

the effects of different shapes and different light distribution curves on the growing shelfs uniformity and light efficiency are studied.
