The design, construction, and ray simulation of a new compound parabolic concentrator based on a toroidal shape (toroidal compound parabolic concentrator, TCPC) are addressed. Such analysis indicates that the amount of concentrated radiation is independent of the Sun trajectory. Thus, the TCPC has the advantage of concentrating Sun rays in a spot, and if positioned with an inclination corresponding to the latitude, a solar tracker would not be needed. Experimental measurements with a prototype model are shown to be in good agreement with the simulation results. The possibility of a variety of applications, as natural illumination for this TCPC device, is also pointed out. The simple design, fabrication, and implementation of the TCPC make it an excellent alternative for low concentration in a spot. We present the analysis of the TCPC in natural illumination as one of these applications.
本文探讨了一种基于环形形状的新型复合抛物面聚光器（环形复合抛物面聚光器，TCPC）的设计、构造及光线模拟。此类分析表明，聚光辐射量与太阳轨迹无关。因此，TCPC具有将太阳光聚于一点的优势，并且如果其倾斜角度与纬度相对应，则无需太阳跟踪器。原型模型的实验测量结果与模拟结果吻合良好。文中还指出了该TCPC装置作为自然照明的多种应用可能性。TCPC简单的设计、制造及应用使其成为点光源低聚光的理想选择。我们将TCPC在自然照明方面的分析作为其中一种应用进行介绍。
