Abstract

PURPOSE: To form a fluorescent substance film capable of improving initial light output of fluorescent lighting and bond strength of fluorescent substance film, by using an aqueous solution obtained by blending several kinds of hydroxyalkyl cellulose in a specific ratio.
CONSTITUTION: An aqueous solution of hydroxyethyl cellulose is blended with 10W50 wt.% of an aqueous solution of hydroxypropylmethyl cellulose or that of hydroxypropyl cellulose. A fluorescent substance is added to the resulting mixture to form a fluorescent dispersion, which is applied to the inner surface of the glass tube and dried. The glass tube is heated to form a fluorescent substance film.
