Abstract

PURPOSE:To avoid the decrease of the initial light-flux and the life-performance characteristics of a curved fluorescent lamp, by making a heat-proof metal oxide containing sodium to be added to a fluorescent-body film, which is affixed to the inner wall of an airtight case made of either a soda-lime glass or a low lead glass. CONSTITUTION:An airtight case is made of either a soda-lime glass which has a softening point of 640-720 deg.C and a linear-expansion coefficient of 92-105X 10<-7>cm/cm/ deg.C, or a low lead glass which contains not more than 12wt% of lead oxide. The inner wall of this case is coated with a fluorescent-body film, which is added with 0.05-1wt% of a heat-proof metal oxide which contains not more than 0.0004wt% of sodium.
