Abstract
PURPOSE: The titled lamp, consisting of a novel composition containing an aluminate fluorescent substance activated with Ce, Tb and Mn of specific composition formula as a green emission luminous body and a blue and a red emission fluorescent substances in a specified proportion as a fluorescent film, and having a high color rendering and emission brightness with a slight change with time.
CONSTITUTION: A fluorescent lamp consisting of a novel mixed composition containing (A) 20W70wt% aluminate green fluorescent substance, activated with Ce, Tb and Mn, and expressed by formula I [Me is Mg, Zn, etc.; w, x, y, z, p and q are as follows: 0≤w≤2; 5≤x≤15; 0.001≤y≤0.20;0<z≤0.5; 0.005≤p≤0.90; 0<q≤0.60; 1-p-q≥0,preferably p+q=1], (B) 3W40wt% bivalent metallic aluminate blue emission fluorescent substance, activated with Eu+2, and expressed by formula II (MIII is Mg, Ca, etc.; 2≤a≤10)and (C) 10W 70wt% rare earth oxide red emission fluorescent substance, activated wit Eu, and expressed by formula III (Ln is yttrium, gadolinium, etc.) as a fluorescent film.
