Abstract

PURPOSE: A fluorescent lamp slightly balcking at the end of pipe, provided with a fluorescent film comprising a fluorescent substance for blue emission of a halo- boron phosphate activated by bivalent Eu, a fluorescent substance for green emission of rare earth sulfide activated by Tb, etc., and a fluorescent substance for red emission of rare earth oxide activated by Eu.
CONSTITUTION: The desired fluorescent lamp provided with (A) a fluorescent substance for blue emission shown by the formulaI(M and M' are Sr, etc.; X is Cl, etc.; 2.7≤x≤3.1; 0.50≤y≤1.5; 0.10≤a≤0.50; 0.01≤b≤0.50; 0.01≤p≤ 0.20),(B) a fluorescent substance for green emission selected from one or more of the formulas II, III, and IV (LnI and LnII are Y, Ln, Gd, etc.), and (C) a fluorescent substance for red emission shown by the formula V (LnIII is Y, LN, Gd, etc.). The most preferable weight ratio of A:B:C is (5W45):(20W70):(10W60).
