Mathematical analysis of the static solar concentrator with cascading right-angle prisms
Abstract
A design of the static solar concentrator with cascading right-angle prisms is proposed to guiding sunlight into indoor for illumination. In this paper, the input- output relationship between incident and exit light for the parallel light impinging on a single right-angle prism was investigated in two-dimensional conditional analysis. We propose the mathematical models to analyze the collection efficiency on the relationship between cascading right-angle prisms and the path of the sun. The proposed models have been verified by FRED optical design software. The simulation on the examples indicates the proposed mathematical models are effective and feasible, consistent with that of the FRED.

With the detection in 2002 of a novel photoreceptor cell in the eye, the biological effects that light has can be better understood. From the research on the biological effects of lighting, it is evident that the rules governing the design of good and healthy lighting installations are, to a certain degree, different from the conventionally held rules. We demonstrate that it can be beneficial to be able to adapt both the level and the colour of the lighting. Not only the light on the visual task, but also that entering the eye determines the overall quality of lighting. In a working environment, not only are the advantages in terms of health and wellbeing important for the workers themselves, they also lead to better work performance, fewer errors, better safety, and lower absenteeism.
In recent years, green energy has undergone a lot of development and has been the subject of many applications. Many research studies have focused on illumination with sunlight as a means of saving energy and creating healthy lighting. Natural light illumination systems have collecting, transmitting, and lighting elements. Today, most daylight collectors use dynamic concentrators; these include Sun tracking systems. However, this design is too expensive to be cost effective. To create a low-cost collector that can be easily installed on a large building, we have designed a static concentrator, which is prismatic and cascadable, to collect sunlight for indoor illumination. The transmission component uses a large number of optical fibers. Because optical fibers are expensive, this means that most of the cost for the system will be related to transmission. In this paper, we also use a prismatic structure to design an optical coupler for coupling n to 1. With the n-to-1 coupler, the number of optical fibers necessary can be greatly reduced. Although this new natural light illumination system can effectively guide collected sunlight and send it to the basement or to other indoor places for healthy lighting, previously there has been no way to manage the collected sunlight when lighting was not desired. To solve this problem, we have designed an optical switch and a beam splitter to control and separate the transmitted light. When replacing traditional sources, the lighting should have similar characteristics, such as intensity distribution and geometric parameters, to those of traditional artificial sources. We have designed, simulated, and optimized an illumination lightpipe with a dot pattern to redistribute the collected sunlight from the natural light illumination system such that it equals the qualities of a traditional lighting system. We also provide an active lighting module that provides lighting from the natural light illumination system or LED auxiliary sources, depending on circumstances. The system is controlled by a light detector. We used optical simulation tools to design and simulate the efficiency of the active module. Finally, we used the natural light illumination system to provide natural illumination for a traffic tunnel. This system will provide a great number of benefits for the people who use it.
One- and two-stage concentrations using wedge-shaped concentrators were proposed as static solar concentrators, where the light changes its direction with specular reflection at the rear surface and refraction or total internal reflection at the front surface. The condition for the total internal reflection gives the critical tilt angle of the wedge and consequently determines the maximum value of the concentration ratio. When the tilt angle is larger than the critical one, only the reflection at the front surface lowers the collection efficiency. Two-stage concentration can give a higher concentration ratio than one-stage concentration. A truncated-cone-shaped concentrator with tracking system can give higher concentration ratios than the two-dimensional wedge-shaped concentrators.
Optical daylighting technology can deliver natural light to a space in a building where daylight is limited. This study gives an overview of two optical daylighting systems for capturing natural light: light pipe systems and mirror sunlighting systems. The literature on optical system theories and developments is identified and commercial products for optical daylighting systems on the market are described. By using a survey of major applications for optical daylighting systems, this study provides practical advice to building designers and researchers and also shows a light pipe system and a mirror sunlighting system developed from this investigation as well as an evaluation of their performance. The evaluation measured the illuminance of the two optical systems installed in a test room and a living room. This study concluded that optical daylighting systems can provide adequate visual comfort and can save energy if they are carefully designed.
Non-imaging optics, well known for its application to solar concentrators, was used to set up novel daylighting systems that aim at an efficient collection and redistribution of the diffuse component of daylight. These devices, called anidolic systems (an: without, eidolon: image), were designed, installed and monitored on experimental test modules under clear and overcast sky conditions. Three different anidolic systems with different specific objectives were considered (anidolic ceiling, integrated anidolic system, anidolic solar blinds). Installed on 6.55-m deep rooms, the first two showed a significant improvement of daylight factors monitored in overcast conditions in comparison to a reference facade (conventional double glazing): a substantial improvement of the daylighting autonomy can be expected as a consequence. Higher work plan illuminances were observed for the third system under clear sky conditions, demonstrating sunlighting control capabilities that improve visual comfort and overall performance. The present article gives a description of these anidolic systems, as well as an overview of their luminous performance, assessed experimentally within the framework of IEA Task 21.
For some time there has been the need to bring new technologies utilising daylight in buildings and to assess their performance for the benefit of those concerned with the building industry, particularly building design practitioners, lighting engineers, builders, product manufacturers, building owners and property managers. As there are many different systems with different purposes and abilities on the market, it is difficult to find the right one. An overview with division into main principles, illustrating sketches and short descriptions of the elements helps a lot to choose the right daylighting system for given conditions. More detailed descriptions can be found in the source book of IEA Task 21.
