METHOD OF DETERMINING SPATIAL DISTRIBUTION OF ERYTHEMA RADIATION FORCE WHEN DESIGNING IRRADIATORS Russian patent published in 2024 - IPC G01J1/56 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering and relates to a method for determining spatial distribution of erythema radiation force. Method involves determining distribution of irradiance over a sphere surrounding the irradiator in the UV-A and UV-B ranges. Relative spectral distribution of radiation in the wavelength range of 280–400 nm is also obtained. Further, determining the conversion factor of energy values into erythemal values by dividing the relative spectral distribution of radiation into the UV-A and UV-B ranges, determining integral of relative spectral distribution of radiation in UV-A and UV-B regions, determining integrals of the radiation overlapping spectrum of the irradiator and the erythema action spectrum in the UV-A and UV-B regions and calculating the erythematous irradiation in the UV-A and UV-B ranges by multiplying the irradiance by the conversion coefficients. Final erythema exposure is determined by summing the obtained values in the UV-A and UV-B regions and increasing the photometry distance by the square.

EFFECT: enabling measurement of erythemal radiation force in the absence of radiation receivers corrected to the erythemal efficiency curve.
