阅读说明：本技术 菲涅尔聚光装置和聚光式太阳能系统 (Fresnel condensing device and condensing solar system ) 是由 胡笑平 于 2017-07-03 设计创作，主要内容包括：一种菲涅尔聚光装置和聚光式太阳能系统,其中聚光装置包括第一和第二菲涅尔透镜层(110,130),每个透镜层包括至少一个聚光型菲涅尔透镜(111,131)；以及一直筒形导光层(120),第一和第二菲涅尔透镜层(110,130)分别设置于其两端,直筒形导光层(120)用于将来自第一菲涅尔透镜层(110)的光线(LL)向下引导至第二菲涅尔透镜层(130)。通过采用两个菲涅尔透镜层(110,130)分别进行光线的汇聚,中间使用直筒形导光层(120)协助将光线从上层向下层引导,使得聚光装置不仅能够具有宽广的入射角度适应范围,还能够在较低的高度下获得较大的聚光比,避免了对跟日系统的依赖。(Fresnel light-gathering device and light-gathering solar system, wherein the light-gathering device comprises a th Fresnel lens layer and a second Fresnel lens layer (110,130), each lens layer comprises at least light-gathering Fresnel lenses (111,131), and a straight cylindrical light-guiding layer (120), the th Fresnel lens layer and the second Fresnel lens layer (110,130) are respectively arranged at two ends of the light-gathering layer, the straight cylindrical light-guiding layer (120) is used for guiding light (LL) from the Fresnel lens layer (110) downwards to the second Fresnel lens layer (130), the light gathering is respectively carried out by adopting the two Fresnel lens layers (110,130), the straight cylindrical light-guiding layer (120) is used in the middle to assist in guiding the light from the upper layer to the lower layer, so that the light-gathering device not only has a wide incident angle adaptation range, but also can obtain a larger light-gathering ratio at a lower height, and the dependence on a solar system is avoided.)
