Lighting Device with Variable Spectral Composition for Growing "Chlorella" in Artificial Conditions

Article Preview

Abstract:

In the paper the basis for the use of the LED light sources in the space greenhouses is described. It is shown that the change in the spectral composition and the intensity of the radiation will reduce the electricity consumption of the irradiation facilities. The unicellular alga "Chlorella" and the greenhouse lettuce "Afitsion" were chosen as prototype models. On the basis of the experiments conducted, the basic principles of the irradiator’s energy efficiency that can be applied in the space greenhouses were defined.
