Suitabilityof Monochromatic Model for Spectrum of Colored LEDs

Abstract

Influence of width of spectrum of coloured LED is analysed on accuracy of descriptions of radiation at measuring power, photonic, light units and in the colorimetery. An analysis is made by the methods of mathe­matical simulation, triangle symmetric and asymmetrical spectrum were utillized. The maximal widths of the spectrums of radiation were estimated on the basis of a normative document and measurings chains. It is well-proven that application of the monochromatic approaching it admits in the limited cases.
