Abstract

PURPOSE:To make uniform the thickness of a film a phosphor is coated with, to prevent color shading and to improve the external appearance by a method wherein, when a linear bulb is heated and softened while the bulb is held in the vertical direction, its elongation is equalized. CONSTITUTION:By forming a heat resistant radiation-reflecting film 2 having a melting point of 600 deg.C or over on the external surface in the end portion of a sealed linear bulb 1 along its axial direction, for instance, using white powder of a white phosphor and the like, the external surface in the end portion of the linear bulb 1 is coated with the radiation-reflecting film 2. Next the linear fluorescent lamp is placed in a heating furnace in such a way that the radiation- reflecting film 2 is located in the upper portion of the lamp, and the linear bulb 1 is heated and softened while it is being vertically held. After this, the bulb is formed into a tube and the radiation-reflecting film 2 is wiped to remove the film from the tubular bulb. Then bases and the like are attached to the tube through the usual method to complete a tubular fluorescent lamp.
