Abstract

A theoretical study has been made of the optical properties of two-component phosphor blends for fluorescent lamps. The component spectral energy distributions were taken to be gaussian when the number of emitted photons is plotted vs energy. Mercury lines were added. The widths, positions, and proportions of the components were systematically varied in such a way as to keep the blend chromaticity coordinates constant. Luminosity and color-rendering indices were computed. Optimum blends for daylight, cool white, white, and warm white lamps were determined in terms of a quality index, which measures the combination of brightness and color rendition.
