Abstract

PURPOSE:To suppress the occurrence of the peeling, crack of the coating and to prevent the deterioration of the light output and the valve strength, by coating the inner face the valve with the phosphor material mainly composed of antimony, manganses activated calcium halo-phosphate phosphor material containing specific amount of phosphor particle having specific grain size. CONSTITUTION:The glass valve 1 forming the discharge path is bent at three positions, for example, into the cubic W-shape and formed such that the discharge path as long as possible is obtained in the small occupied volume while having the inner face coated with the phosphor film 2. Said phosphor coating is composed of the phosphor material mainly composed of antimony, manganese activated calcium halo-phosphate containing 10-50wt% of the phosphor particle having the grain size smaller than 3mu. Consequently the phosphor coating is never peeled at the bending section while the light output is never deteriorated and the deterioration of the strength of the valve can be prevented.
