PURPOSE:To enhance the luminous efficacy as well as the color rendering of a fluorescent lamp, by combining 3 kinds of given fluorescent-body films. CONSTITUTION:The fluorescent-body film of a fluorescent lamp is constituted of the combination of 3 kinds of fluorescent-body films. The 3 kinds of films comprise: a calcium-halophosphate phospher activated with antimony-manganese which has a peak wave-length of 570-575nm; a red phosphor made of yttrium oxide activated with trivalent europium; and a blue phosphor having a peak wave-length of 440- 460nm, preferably a strontium-calcium-chloroapatite phosphor activated with bivalent europium. |
