Abstract

PURPOSE:To aim at forming a phosphor film inside a glass tube, on which a phosphor suspension is applied uniformly by injecting the phosphor suspension from an opening end into the glass tube before the glass tube is caused to turn round while it is being moved downward so that the phosphor suspension is fluxed. CONSTITUTION:A U-glass-tube 1 is held with its opening ends 11a, 12b up, and the phosphor suspension 3 is injected from one opening end into the tube 1. Subsequently, leaving the opening ends 11a, 12b as they are up, the tube 1 is grasped with a holder 21. The holder 21 makes a swinging movement integrally with a shaft 22 at a prescribed speed, while, the tube 1 changes the direction gradually while describing a circular orbit in the direction of the arrow A and it is turned upside down. During this space of time, the suspension 3 in the tube 1 fluxes gently from the opening ends 11a, 12b while it is subjected to the acceleration produced in the direction the tube moves, Thereby, the air cannot be included in the suspension 3 within the tube 1, and consequently, an uniformly applied film can be obtained.
