METHOD FOR ORGANIZED ARRANGEMENT OF OPTICAL RADIATION SOURCES OF RADIATION SYSTEM USED FOR PLANT GROWING Russian patent published in 1998 - IPC

FIELD: agriculture, in particular, growing of plants in climatic selection systems with higher radiation mode requirements. SUBSTANCE: method, based on dependence of spectral composition of radiation on supply voltage value and lamp operating time, as well as on voltage losses in elongate electric lines, involves uniform distribution of loading obtained on the basis of technical calculations between supply mains phases and groups; providing groups of light sources with spectral parameters required depending on purpose of radiation unit; determining and setting operating time of light sources used in the process on the basis of test results; using known dependence of radiation spectral composition on supply voltage and determining the supply voltage value at which spectral deviations are minimum; determining actual voltage value of each radiator in accordance with length of group line; equipping radiators with light sources providing joint standardized spectral parameters of radiation medium in growing construction for plants or for current vegetative phase. EFFECT: increased efficiency by maintaining standardized indicators of radiation mode of greenhouses at required level. 2 dwg, 1 tbl
