“…The prototype daylighting system is divided into two parts: light collection and light transmission. The novel optical design principles are divided into three categories: collection [33,100,[111][112][113][114][115], transmission [99] and collection with transmission [32,[38][39][40]44,47,49,52,56,96,103,106,116] (Table 8).…”

Daylighting systems make daylight illuminance possible, and the development of prototype daylighting systems can provide more efficient daylight illuminance. The purpose of this article is to review the development and performance of prototype daylighting systems in the last decade. The passive and active daylighting systems are listed separately and divided into the four categories by the presence and absence of hybrid. Each prototype daylighting system was evaluated in terms of cost and daylight performance and as well as their novel optical design. We evaluated the architecture and daylighting principles of each system by reviewing individual prototype daylighting systems. The cost of prototype systems still poses a challenge to development. How to use passive or active systems in different environments and whether or not electrical lighting assistance is needed is a controversial issue. However, active daylighting systems equipped with solar tracking systems are still mainstream. This research is a valuable resource for daylight researchers and newcomers. It is helpful to understand the advantages of various prototype daylighting systems and commercial daylighting systems that have been developed for many years; moreover, it is also possible to know the research directions suggested by the prototype daylighting systems. These will be of further use in developing innovative and better daylighting systems and designs.

Metal nanoparticles (NPs) with subwavelength dimensions exhibit plasmonic phenomena in resonance frequency and can absorb a portion of light non-radiatively and thermally. This property of NPs can be used in various applications such as seawater desalination, where the thermal power generated by them can be utilized. In this paper, we have designed and analyzed NPs to achieve maximum absorption and heat generation under solar irradiance. The NPs were arranged on a glass substrate in the most optimal pattern to obtain the highest possible absorption and heat generation. We utilized a numerical method to determine the total absorbed power of the NPs under solar irradiance. The shape, material, size and arrangement and interaction of the NPs determine their optical behavior, and, as a result, their thermal behavior. Therefore, we designed cylindrical, cubic, triangular, and hexagram-shaped NPs with the same volume of metal, choosing the material from noble metals such as Ag, Au, Cu, and Al. In the first step, we calculated the absorption cross-section of NPs using the Finite Difference Time Domain (FDTD) method. We then multiplied the solar irradiance intensity by the cross-section obtained in the first step. In the final step, we integrated the graph obtained in the solar spectrum to obtain the total absorbed power of the NPs. To determine the best arrangement period of the NPs, we utilized the Particle Swarm Optimization (PSO) method. This algorithm helped us find the period with the highest absorbed power. Aluminum hexagram nanoparticles, having the highest absorbed power and cost-effectiveness in manufacturing, were considered as the main candidates for the structure.

Because a traditional optical fiber light guiding system includes a tracking device, it also inevitably has a complex structure, high construction and maintenance costs, short life span and low reliability. Although several types have been developed for decades, there are no successful products on the market. The biggest cause of the problem is that all traditional optical fiber light guiding systems must have a tracking device. This paper studies a solar fiber optic guide system without a tracking device, hoping to solve this problem. A fixed fiber light guide system using concave outlet concentrators as its receiving unit is proposed. The structure and working principle of the concave outlet concentrator, the receiving unit and the light guide system are introduced. With optical simulation software and the actual sunlight experimental method, this paper first discusses the conceptual design of the concentrator, then studies the transmission efficiency curve of the receiving unit with different angles of incident light, and finally tests the output illuminance of the whole system in actual sunlight. Field test results show that when the average sunshine intensity is about 800 W/m2, the system has an output of nearly 300 lux at 0.4 m in front of the outlet end of the fiber bundle with only receiving area. This illumination has been able to meet people’s daily lighting requirements. The results of computer simulation and actual sunlight experiments show that this fixed optical fiber light guide system with non-tracing structure is feasible. The absence of a tracking structure means that all moving parts of the system are completely discarded. This greatly improves the working reliability and operation life of the light guide system, and greatly reduces the maintenance and operating costs.
