[Some bioengineering and hygienic aspects of incorporating sodium light illuminators into space life support systems]

Some bioengineering aspects of utilizating high-pressure sodium lamps (HPSL) in space plant growth chambers are reviewed. Comparative feasibility analysis of various lighting systems currently used in plant industry, and investigation of HPSL limitations and advantages allow the conclusion about their good prospect as a component of future plant growth facilities aboard long-term space bioengineering life support systems. High appraisal is given to the design of a board prototype of the DnaTSf-70 sodium lamp. Associated sanitary-hygienic regulations developed, HPSL are liable to be also used to lighten the spacecraft interior.
