Abstract

PURPOSE:To obtain a fluorescent lamp whose fluorescent film thickness is uniformly coated by coating and drying the fluorescent suspension, standing tubes on their ends, using the stream down method, inverting the tubes, and re-coating the fluorescent suspension in the same process. CONSTITUTION:The glass tube 2 for a direct tube fluorescent lamp is vertically supported and the fluorescent suspension 1 which is injected from the nozzle 6 and flows down is coated on the tube wall of the tube 2 using the stream down method. Then by heating and drying the fluorescent suspension using the heating air which is injected from the injection tube 9, the first-layer fluorescent coat is coated on the tube wall. After that, the tube 2 is inverted. In this state, the second-layer fluorescent coat is coated on the first-layer one by using the same method by which the first-layer coat is coated.
