Development of an optical system for lighting rooms with biologically safe and environmentally friendly sunlight

Abstract

The article discusses the development and advantages of an optical system for lighting rooms with biologically safe and environmentally friendly sunlight. A passive system that does not consume energy is proposed. The analysis of artificial light sources by their spectral composition is carried out. It was found that the spectral composition most suitable for a comfortable human condition is an incandescent lamp, which has several limitations. It is established that the most environmentally friendly and safe solution is the use of sunlight. An energy-efficient natural light system has been developed, creating a comfortable environment for the eyes, well-being, and mood of a person.

“…The development of technological progress has led to an increase in the load on the technosphere of the planet [1][2][3][4][5][6][7]. Negative processes affect various components of the environment (air, water, green spaces and soils) [2,3,6,[8][9][10][11][12][13][14][15]. The sharp reduction of forests and green areas has led to a decrease in the ability to process emissions of carbon dioxide and other harmful substances [1,3,8,9,[16][17][18][19].…”
