PURPOSE:To obtain the high color rendering properties and high luminous efficacy of a fluorescent lamp concurrently by arranging the chromaticity of luminous colors within the chromaticity range enveloped by multiple coordinate points in the 1931 x, y chromaticity coordinates based on the 1960 CIE-ucs chromaticity system. CONSTITUTION:The chromaticity of luminous colors is determined to be within the chromaticity range enveloped by the first coordinate point (x=0.346, y=0.362), second coordinate point (x=0,356, y=0.375), third coordinate point (x=0.337, y=0.352), fourth coordinate point (x=0.348, y=0.381), fifth coordinate point (x=0.359, y=0.390), and sixth coordinate point (x=0.338, y=0.370) as shown in the figure. Halo strontium phosphate activated with europium for a blue luminous phosphor, cerium .magnsium aluminate activated with terbium for a green luminous phosphor, and yttrium .vanadium silicate activated with europium for a red luminous phosphor were used in combination to produce a fluorescent lamp for trial, and a desired objective was attained to occupy within the coordinate range mentioned above. |
