Abstract
This article analyzes and compares three daylighting technologies: light pipes, optical fibers, and heliostats. This work aims to evaluate their efficiency, sustainability, and cost-effectiveness in providing natural light to indoor spaces. The analysis includes a review of the principles behind each technology, the design and development of the prototypes and experiments carried out by our research team, their advantages and disadvantages, and their applications in different settings. The comparison is based on several criteria, such as installation, cost, efficiency, output spectrum, and hybrid system. The results indicate that each technology has its unique features and is suited to specific applications. Light pipes are effective for short distances, and they can be easily integrated into existing buildings. Optical fibers are suitable for long distances and offer flexibility in design, but they require more maintenance. Heliostats are ideal for large spaces, but they are expensive to install and operate. Overall, this study provides valuable insight into the strengths and weaknesses of three daylighting technologies and helps designers and architects make informed decisions when selecting the most appropriate solution for future work.
