Using Solar Optical Fibers for Public Buildings Illumination in the South Urals

AbstractThe article shows the problem of energy shortage and justifies the necessity of energy-saving activities to be applied in the lighting of buildings. The analysis of solar radiation throughout the year and the length of daylight availability in Chelyabinsk region is made. Based on the analysis of designs and technical characteristics of solar optical fibers their use in newly constructed buildings and social facilities is justified, disclosing the terms of using solar optical fibers in the Urals conditions. The data on the changes of the natural lighting in the room, depending on the time of the day, cloudiness, and the location of the buildings to the cardinal points is produced, the expediency of the combined lighting systems “solar optical fiber+ light-emitting diode” application, which will significantly reduce the lighting costs, is illustrated
