Abstract:The historical aspects and prospects of the use of artificial light sources in the biological and technical systems of life support for space applications are considered. According to the given data, the most promising for such systems are LED light sources. Based on the results of photobiological studies it is shown that radiation, perceived by a man as white, in his spectral efficiency unreliable differs from radiation, a spectral curve similar to the average action spectrum of photosynthesis the green sheet (“Phyto”). In accordance with this, the possibility of choosing either a phyto spectrum or a spectrum close to the equal energy for the cultivation of plants in life support systems is justified.
