“…5.1 that have been reported in this work except for the work by (Ochieng and Onyango, 2009). However, variants of this concentrator such as the straight cone type in which some literature can be found, (Williamson, 1952), (Witte, 1965), (Smith, 1966), (Welford and Wilson, 1978). The inclusion of cylindrical component is a completely a new addition.…”

“…A primitive form of nonimaging concentrator, the light cone has been used for many years (see for example, (Hotler et.al. 1962), (Witte, 1965), (Williamson, 1952), (Welford & Winston, 1978). The option to integrate cost effective storage systems directly into solar thermal facilities represents a significant advantage of solar thermal systems over other concepts using renewable energy sources.…”

“…The cone is far from being an ideal concentrator. (Williamson, 1952) and (Witte, 1965) attempted some analysis of the cone concentrator by restricting their analysis to the meridian rays. The meridian ray analysis gives a very optimistic estimate of the concentrator; however, it does not address the problem of back reflections.…”

“…In comparison with compound parabolic concentrators (CPCs), it shows better performance than cones; however, producing CPCs is more difficult and expensive. Williamson [28] geometrical method of ray tracing in a simple cone, and Witte [29] demonstrated that the same procedure is applicable for skew rays. Myer [30] implemented the same method for the concentration of collimated paraxial rays in a cone.…”

Concentrated sunlight that is transmitted by fiber optics has been used for generating electricity, heat, and daylight. On the other hand, multijunction photovoltaic cells provide high efficiency for generating electricity from highly concentrated sunlight. This study deals with designing and simulating a high-efficiency coupler, employing a mathematical model to connect sunlight with fiber optics for multiple applications. The coupler concentrates and distributes irradiated light from a primary concentrator. In this study, a parabolic dish was used as the primary concentrator, a coupler that contains nine components called a compound truncated pyramid and a cone (CTPC), all of which were mounted on a plate. The material of both the CTPC and the plate was BK7 optical glass. Fiber optics cables and multijunction photovoltaic cells were connected to the cylindrical part of the CTPC. The fibers would transmit the light to the building to provide heat and daylight, whereas multijunction photovoltaic cells generate electricity. Theoretical and simulation results showed high performance of the designed coupler. The efficiency of the coupler was as high as 92%, whereas the rim angle of the dish increased to an optimum angle. Distributed sunlight in the coupler increased the flexibility and simplicity of the design, resulting in a system that provided concentrated electricity, heat, and lighting for residential buildings.

“…The radiation focused by the mirror is deflected into a copper condensing cone [21], which then channels the radiation through a 1.25-mm-thick high-density pblyethylene (HDPE) window of 19mm diameter into a room-temperature bolometer. Since the diameter of the pyroelectric detector is only 5mm, an additional copper condensing cone is installed between the HDPE window and the bolometer to direct all radiation through the window onto the detector surface.…”
