FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement equipment and concerns a method for determining phyto-irradiator degradation based on quasi-monochromatic light-emitting diodes. Method consists in the fact that phyto-irradiators based on light-emitting diodes with blue and red crystals are simultaneously exposed to current for the selected period of time. Phyto-irradiators are divided into three groups. Current is passed through the first group, density of which is less than rated current density, current passing through the second group is passed, equal to nominal value, current passing through the third group is passed, density of which is higher than rated current density. At the selected periodicity, the phyto-irradiators are placed in a photometric sphere, in which the required spectral composition is extracted using red and blue color light filters. Common decrease of light flux with filters and without filters is successively measured. Based on the obtained data, a degradation degree of a phyto-irradiator is determined.

EFFECT: technical result consists in enabling determination of dynamics of radiation flux decay and degree of degradation separately for each crystal of phyto-irradiator.
