| 摘 要： | 讨论并设计了一种超薄的菲涅尔聚光镜,根据费玛原理设计出以非球面为截面的中心折射区域和T IR(内部全反射)棱镜为锯齿部分的折反区域,用ZEMAX软件优化得到最佳聚光态,并利用ZEMAX软件模拟出菲涅尔聚光镜聚光性及其能量分布,最终得到总厚度仅为30 mm的折反复合型菲涅尔聚光镜。实验结果表明:折反复合型菲涅尔聚光镜不仅能提高太阳能的利用率,同时也使会聚到光电池表面上的能量分布更均匀,复合式菲涅尔聚光镜的性能优于传统的菲涅尔聚光镜。

| Abstract: | An ultra-thin Fresnel condenser lens was discussed and designed.According to Fema principle,an aspheric surface was designed as central refraction area,and a total internal reflection(TIR) prism was designed as a catadioptric area in saw-teeth part.The optimal condense performance was achieved with ZEMAX.ZEMAX was used to simulate the concentration and distribution of Fresnel condenser,and a Fresnel condenser with thickness of 30 mm was designed.The compounded Fresnel lens improves the utilization of solar ... |
