LED植物组培灯具的光照均匀性设计

Design of High Illumination Uniformity LED Luminaires for Plant Tissue Culture

随着LED应用产业的不断发展,LED灯正逐步替代传统光源作为植物组培用光源。研究了以两根LED灯管和3根LED灯管为单元在0.6 m2组培区域内的光照均匀度问题,提出了1种不附加光学组件仅改变LED发光颗粒在灯管上的分布位置实现提高组培区域内光照均匀度的方法。两根灯管和3根灯管的组培补光单元内部LED发光颗粒经排布优化后,光照接收面的均匀度均提升了约60%。摘要:

While LED lighting industry is developing very fast,LED luminaires are replacing traditional luminaires as the light sources for plant tissue culture.Uniformity of illumination of 0.6 m2 plant tissue culture shelf illuminated by two and three light tubes is studied respectively.A new method of only optimizing the LED package distribution of the light tubes with no additional optical components to achieve higher uniformity of illumination within the tissue culture shelf is proposed.The uniformity of illumination is improved by about 60 percent for both cases(two and three lighting tubes per shelf).
