N2 - Powering lighting systems using renewable energy technologies, such as solar energy, is a promising solution to improve health, productivity and building energy efficiency. In this research, a novel design for a hybrid sun/LED lighting system has been numerically investigated. The design integrates the Fiber Optics, as a waveguide of the sunlight, to the existing electrical grid infrastructure, to optimize the use of natural daylight during sunlight hours and seamlessly transitioning to energy-efficient Light-Emitting Diodes (LED) when there is not enough light quantitively and qualitatively. Simulation results showed an overall optical transmission efficiency of 32% along 10m-length. Moreover, the luminous efficacy of the visible light transmission was evaluated based on the average illuminance levels achieved within interior spaces indicating substantial indoor lighting enhancements recording 92 Lumens/Watts. The lighting capacity of the system exceeds the average requirement of a standard office space by approximately 30%. The findings of the present work represent a significant advancement towards the commercialization of Fiber Optic Daylight systems (FOD)-Based Fresnel Lens.
