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.

The three practical light emitting diode (LED) biology light sources with different intensity and uniformity have been developed by three schemes of optical system:an array of LEDs being set in the flat surface;in the curved surface;the integration of curved surface and Fresnel len. The affects of four parameters on the illumination in each light source have been researched respectively and their experiential formulae for calculating illumination have been obtained by SPSS .
