Hybrid Solar and Artificial Lighting (HYSAL): Next-Generation Lighting Strategy for Bioregenerative Advanced Life Support

The evolution of lighting systems for Bioregenerative Space Life Support (BLSS) has been brought about by two major challenges confronting current BLSS models: (1) the extensive use of highly energy-intensive artificial lamps; and (2) the substantial energy wastes incurred through heat dissipations by these lamps, frequently dictating unnecessarily large, and costly, physical volumes for the plant growing structures. The results of our studies showed that Solar Irradiance Collection, Transmission and Distribution Systems (SICTDS) should be used to augment artificial lighting for growing plants in a BLSS to constitute a reliable, energy-efficient and mass-optimized Hybrid Solar and Artificial Lighting (HYSAL) system for a BLSS.
