Abstract

PURPOSE: To raise the color rendition of a fluorescent lamp while maintaining high efficiency by reducing the luminance of antimony practically to zero and using calcium halophosphate phosphor of high efficiency yellow luminance mostly of manganese luminance.
CONSTITUTION: 500g of calcium halophosphate of high efficiency yellow luminance having a chromaticity co-ordinates; x=0.447, y=0.450, 250g of europium and manganese activated barium manganese aluminate phosphor, and 150g of europium activated oxi-yttrium sulfide phosphor are mixed well. 6.5g of the mixture is applied to the inner surface of a 40W-glass tube, dried and baked to form a phosphor film 2 over the inner surface of the 40W-glass tube which is processed to produce a fluorescent tube.
