Development of optical systems for additional lighting of premises with sunlight

the necessity of using light for indoor lighting, the spectral composition of which corresponds to the spectrum of the sun, is justified. It is established that this is necessary for a comfortable state of a person. The results of the study of natural light sources by their spectrum are presented. It is established that the full spectrum of solar radiation is contained in incandescent lamps, which are short-lived and unsafe at high power. The obtained research results showed that the safest solution to the problem is the use of additional sunlight. An optical system has been developed for transmitting sunlight from the roof of a building to residential and utility rooms via optical fibers. An experimental study of the system operation was carried out. The results of experimental studies are presented.
