Abstract

PURPOSE:To obtain the improved color rendition and efficiency at a color temprature of 4,000-7,000 deg.C by using a fluorescent film of a specific composition. CONSTITUTION:A fluorescent film 2 is provided on the inside surface of a glass tube 1. The fluorescent film is composed of a mixture of 1-45wt% of a halogenated calcium phosphate phosphor activated with antimony, 40-86wt% of a halogenated strontium phosphate phosphor activated with anitmony and manganese, 3-17wt% of yttrium oxysulfide phosphor activated with europium, and 2-10wt% of yttrium oxide phosphor activated with europium.
