"Artificial Sunlight" is a foundational exploration of the intersection between lighting technology and human health. Written by M. Luckiesh, a pioneer in the science of illumination, this work delves into the dual purpose of light: providing visibility and promoting biological well-being. The text examines the physics of radiant energy, comparing the properties of natural sunlight with the capabilities of artificial light sources available in the early 20th century.Luckiesh investigates the physiological benefits of ultraviolet radiation, discussing how lighting systems can be designed to mimic the beneficial effects of the sun. The book covers essential topics such as the measurement of radiation, the biological effects of different wavelengths, and the practical application of light therapy in residential and industrial environments. By bridging the gap between physics and hygiene, "Artificial Sunlight" serves as a significant historical document in the development of lighting design and environmental health science. It offers unique insights into the evolution of our understanding of how the indoor environment affects human vitality and the technical challenges of replicating the qualities of the natural world through engineering.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
