AbstractThe solar-ray supply system presented here will mainly provide the visible solar ray necessary for the various activities in the space station, such as cultivation experiments on plants, fishes, birds and animals, room lighting for modules, and crew sun-bathing. Even natural solar rays reaching earth surface contain harmful rays for human beings, animals, higher plants and algae: Ultraviolet rays of medium (UV-B) and long wavelength (UV-A), infrared and heat rays, are all harmful to life. On a space station, the most dangerous short-wavelength ultraviolet (UB-C), X-ray and gamma-ray are additionally included, besides those cited above in markedly higher intensity. The range of rays useful and harmless to life is the visible band of wavelengths. No conclusive studies have been conducted concerning the unexpected powerful effects on the growth of plants and algae that can be brought by pure visible solar rays, in comparison with the corresponding effects of other kinds of artificial light source.
