Abstract

PURPOSE: A fluorescent lamp having high lamp efficiency and coloring properties, obtained by forming a fluorescent substance layer comprising respectively specific fluorescent substance of yttrium oxide activated by Eu, fluorescent substance of bivalent metal borate activated by Ce and Tb, and blue fluorescent substance in the inner face of a glass tube.
CONSTITUTION: A fluorescent substance layer comprising (A) a fluorescent substance of yttrium oxide activated by Eu having an Eu concentration of 0.04W0.08atom based on 1g Y atom, (B) a fluorescent substance of bivalent metal borate activated by Ce and Tb shown by the formula (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 blue fluorescent substance putting a blue color consisting essentially of a range of wave length of 430W470 nm, slightly emitting ultraviolet rays, requiring aline and/or band spectrum having band range of <40 nm is formed in the inner face of a glass tube, to give the desired fluorescent lamp.
