通过采用平面LED点阵、半球曲面内LED点阵、半球曲面与菲涅耳透镜结合这三种光学设计 ,本文研制出具有不同光强和光照均匀差别的三种实用型LED生物光源 ,研究了每个光源中的四个工作参数对其辐射照度的影响 ,并使用统计分析软件SPSS拟合得出它们的辐射照度经验计算公式
By using three kinds of optical design such as flat LED dot matrix, LED dot matrix in hemispherical curved surface, hemispherical curved surface and Fresnel lens, three practical LED biological light sources with different light intensity and uniform illumination have been developed. The influence of four working parameters of each light source on their irradiance and the empirical formula of their irradiance using the statistical analysis software SPSS
