Abstract

PURPOSE: To provide a bent tube type fluorescent lamp which does not cause any problems on environmental pollution and exhibits similar light output characteristics to those of lead glass, by depositing a calcium halophosphate phosphor having a specified composition on the inner surface of a bulb made of soda glass.
CONSTITUTION: There is prepd. a halophosphate phosphor of the formula, wherein M is a bivalent metal such as calcium, manganese, barium, strontium, cadminum or magnesium; X is halogen; a is 0.17W0.5. A metal borate, ethyl cellulose and a solvent are mixed with the resulting halophosphate phosphor to produce a coating liquid which is then coated on a bulb made of soda glass. The both ends of the bulb are sealed by using stem mounts. Then the bulb is heated to a temp. not lower than the softening point thereof and is bent into a circular shape to produce the desired bent tube type fluorescent lamp.
