Abstract

PURPOSE: To obtain a fluorescent lamp having improved luminescent outputs during a lighting period, provided with a fluorescent film composed of a blue light-emitting divalent Eu-activated halophosphate fluorescent substance, a green light-emitting Ce, Tb-activated rare earth element aluminophosphate fluorescent substance, and a red light-emitting Eu-activated rare earth oxide fluorescent substance.
CONSTITUTION: A fluorescent film is formed by mixing 3W47wt% blue light- emitting divalent Eu-activated halophosphate fluorescent substance (A) of formula I(where M and M' are each one or more of Sr, Ca, and Ba and Z is one or more of Cl and F) 15W65wt% green light-emitting Ce, Tb-activated rare earth aluminophosphate fluorescent substance (B) of formula II (where Re is one or more of Y, La, and Gd, and a, b, x, and y are in the relationships 0<a, 0<b, 0<a+b<1,0<x, and 0<y), and 10W70wt% red light-emitting Eu-activated rare earth oxide fluorescent substance (C) of formula III (where Ln is one or more of Y, La, Gd, Tb, and Sm).
