Abstract
PURPOSE: To reduce electric power consumption and improve the efficiency of lamp remarkably, without decreasing colour representation estimation number by coating phosphor consisting of yellow and blue-green luminous phosphors of which chromaticity point is in a specific range.
CONSTITUTION: Calcium halo-phosphate phosphor energized by antimony and manganese and barium magnesium aluminate phosphor energized by europium and manganese of which chromaticity point are within 0.425≤x≤0.475, 0.445≤y≤ 0.485 on CIE-xy chromaticity figure are dispersed in buthyl acetate solution containing cellulose nitrate, and phosphor emulsion thus formed is coated on the inner surface of a glass tube, in order to form phosphor membrance. The inner diameter of the glass tube is 18W29mmϕ. Thus, the lamp electric power consumption can be reduced, and the lamp efficiency can be improved markedly, without decreasing average colour representation estimation number.
