ADesign of Fresnel lens for solar concentrator
-
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TIR（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30mm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 30mm was designed. The compounded Fresnel lens improves the utilization of solar energy and provides a better uniformity of energy distribution. The design method generates a better compound condenser than conventional Fresnel condenser.
