为了解决太阳光经传统菲涅尔聚光镜聚光后太阳能电池接收面上的光强分布不均匀问题，设计了一种环带式菲涅尔聚光镜。根据菲涅尔环带设计方法，把接收面划分为与之对应的环带，使光线在经过菲涅尔聚光镜的表面环带后进入相应的接受面环带，减少了光能损失并提高了光强分布均匀性。给出了在350 nm ~760 nm波段范围内太阳张角角度为0.54°、口径200 mm、高宽比为0.65、聚光比为400的菲涅尔聚光系统设计实例，通过Tracepro模拟并分析了菲涅尔聚光镜的光学能力。结果表明：在接收面尺寸相同的情况下与参数相同的的传统匀光菲涅尔聚光镜相比，此环带菲涅尔透镜光斑能量分布均匀性达到75%。

In order to solve the problem of nonuniform distribution of light intensity on the receiving surface of solar cells after the solar light was collected by the conventional Fresnel concentrator,a belt type Fresnel concentrator was designed.According to the Fresnel belt design method,the receiving surface was divided into corresponding zones,which made the light first pass through the surface belt of Fresnel condenser then enter the corresponding receiving surface strip,so as to reduce the optic energy loss and improve the uniformity of light intensity distribution.This paper gave an example of Fresnel condenser system with the solar flare angle of 0.54°,the diameter of 200 mm,the height width ratio of 0.65 and the concentration ratio of 400 in the wavelength range of 350 nm~760 nm,simulated and analyzed the optic capability of Fresnel condenser by Tracepro.Results show that compared with traditional uniform Fresnel lens condenser of the same parameters and in the case of the same size receiving surface,the spot energy distribution uniformity of the belt-type Fresnel lens reaches 75% .
