摘要： A method for manufacturing a fluorescent lamp that can achieve stable luminous characteristics and discharge characteristics and also does not suffer from cracks in the interconnected portion of the glass tubes while handling or lighting the fluorescent lamp is provided. Interconnecting portions located in the vicinity of open end portions of glass tubes that are positioned adjacent to each other are heated respectively from inside to form a welding portion, and then, the glass tubes are thrust against each other and thinned by conducting a preliminary tapping of the welding portion from inside using hammers. Next, the welding portion is opened by conducting a main tapping to form an interconnected portion, and end portions in the vicinity of the interconnected portion are closed by heating and melting, and then the end portions are molded.

摘要： A method for manufacturing a glass tube used for a fluorescent lamp having an arc tube constructed by joining a plurality of glass tubes is provided. According to this method, a straight glass tube held at both ends is rotated, and a predetermined cutting portion of the glass tube is softened by heating, and then the glass tube is moved in the heated state in the direction toward the predetermined cutting portion to form a glass accumulated portion at the area of the predetermined cutting portion. Next, the glass tube is drawn away in the direction receding from the predetermined cutting portion, and the predetermined cutting portion of the glass tube is cut into two glass tubes having self-closing end walls. In this way, the end walls of the self-closed glass tubes can be formed thicker and more uniform compared to those obtained by the conventional techniques, and the mechanical strength of the end walls also can be improved. As a result, the defective percentage of the lamps during the manufacturing process and on the market due to cracks, leakage, or damages in the end walls of the glass tubes can be reduced.
