Abstract
PURPOSE: A fluorescent lamp of the electric power-saving type having high lamp efficiency, comprising a fluorescent substance layer consisting of respectively specific fluorescent substance of rare earth oxide activated by Eu, fluorescent substance of bivalent metal borate activated by Ce and Tb, and fluorescent sub- stance of alkaline earth metal halophosphate activated by Eu.
CONSTITUTION: A fluorescent substance layer consisting of (A) a fluorescent substance of rare earth oxide shown by the formulaI(Ln is Y, Gd, or Lu), (B) a fluorescent substance of bivalent metal borate shown by the formula II (MI is Mg, Be, etc.; MII is Ca, Sr, Ba; 0<a≤2.0; 0≤x≤0.25; 0<y≤0.4; 0.0001≤z≤ 0.4), and (C) a fluorescent substance of alkaline earth metal halophosphate shown by the formula III (Ma is Ca, Ba, etc.; Mb is Ca, Ba, Sr; X is F, Cl, Br) is formed in the inner face of a glass tube having an inner diameter of 20W 29mm, to give the desired fluorescent lamp.
