Abstract
PURPOSE: To improve efficiency and light-flux maintaining efficiency of a fluorescent lamp, by use of a fluorescent material obtained by mixing antimony- or manganese-activated calcium halogeno-phosphate and europium-activated yttrium oxide.
CONSTITUTION: A fluorescent lamp is manufactured by preparing a fluorescent material by mixing 70W90 wt % of antimony-or manganess-activated calcium halogeno-phophate and 10W30 wt % of europium-activated yttrium oxide, having its maxiumum light-emitting peak value at 572 nm, and applying the same over the bulb surface in a customary method. In case that its maximum light-emitting peak value is seleced, in particular, at 572 nm and the above mixing ratio is selected at 83 wt % to 17 wt %, quantity of luminous flux after 100 hour lighting is 3300 Lm and color rendering index is 56. Therefore, lightflux of this fluoescent lamp is more than two times greater than common fluorescent lamps, and at the same time, its light-flux maintaining efficiency can be also improved.
