Abstract

PURPOSE: To better the color renderability and luminous brightness of a fluorescent lamp, by using a luminous composition containing a Ce, Tb-activated divalent metal borate fluorescent substance, a divalent Eu-activated divalent metal inorganic acid salt fluorescent substance, and an Eu-activated rare earth element-containing fluorescent substance as a fluorescent film.
CONSTITUTION: As a fluorescent film, a composition, consisting of 20W70wt% a green-color luminous fluorescent substance, e.g., one or more of the compounds of the formula I (where M1 is one or more of Mg, Be, Zn, and Cd, MII is one or more of Ca, Sr, and Ba, and 0<a≤2.0, 0≤x≤0.25, 0<y≤0.4, and 0.0001≤z≤4), 3W40wt% a blue-color luminous fluorescent substance, e.g., one or more of the divalent Eu-activated divalent metal aluminate compounds of the formula II (where MII is one or more of Be, Mg, Ca, Sr, Ba, Zn, and Cd, and 2≤b≤10), and 10W 70wt% a red-color luminous fluorescent substance, e.g., one or more of the Eu- activated rare earth element oxide, acid sulfides, and yttrium vanadate fluorescent substances, represented by the formulas III, IV, and V (where Ln is one or more of Y, Gd, Lu, and La), is used.
