MEASURING COLORIMETRIC CHARACTERISTICS OF THE LIGHT SOURCES
The paper deals with colorimetric characteristics of light sources. Details of the technique of measurement of the chromaticity coordinates of the method of weighted coordinates. The physical meaning of the concept "ordinates of curves of addition", "color coordinates" and "chromaticity coordinates" is considered. A brief description of the alternative two-coordinate model of color vision is given. The description of the installation for the measurement of colorimetric characteristics of led light sources, laboratory technology of manufacturing and research of LEDs with "remote" phosphor and the procedure for calculating the chromaticity coordinates of the measured emission spectra.
