摘要： Two arc tubes which are to be connected are held at different levels. Predetermined portions in the vicinity of an end of each arc tube are evenly heated and softened by a flame of a burner from the side. An air flow is supplied to blowing up the softened portion to form a semi-junction bridge having a circular cross-section and a flat connecting face. The thickness of the wall of the semi-junction bridge is even. The arc tubes having the semi-junction bridges are disposed on the same plane and one arc tube is moved to the other to connect the semi-junction bridges while the connecting faces are softened.

摘要： This invention provides a compact, efficient and well-designed circular fluorescent lamp with high output power. The circular fluorescent lamp has less non-luminant region and good characteristics of luminous intensity distribution, and keeps high level of lamp lumen output. Circular arc tubes are disposed concentrically on the same plane. Electrodes are attached to the tube-end parts of the one side of the circular arc tubes respectively, and the other tube-end parts of non-electrode side are sealed. The circular arc tubes are joined each other near the tube-end parts of the non-electrode side with a bridge-jointed portion, so that a discharge path is formed between the electrodes inside the arc tubes. The tube outer diameter of the circular arc tubes is 14 mm, the circle outer diameter of the outer circular arc tube is 150 mm, and the circle inner diameter of the inner arc tube is 90 mm. The distance measured along the center line of the tube from the point corresponding radially to the end part of the bridge-jointed portion to the sealed tube-end part of the outer circular arc tube is 11 mm, and the distance measured along the center line of the tube from the point corresponding radially to the end part of the bridge-jointed portion to the sealed tube-end part of the inner circular arc tube is 6 mm.

摘要翻译： 本发明提供了具有高输出功率的紧凑，高效和精心设计的圆形荧光灯。 圆形荧光灯具有较少的非发光区域和良好的发光强度分布特性，并保持了较高的灯管流明输出。 圆弧管同心地放置在同一平面上。 电极分别连接到圆弧管一侧的管端部分，非电极侧的另一个管端部分被密封。 圆弧管在非电极侧的管端部附近具有桥接部，从而在电弧管内的电极之间形成放电路径。 圆弧管的管外径为14mm，外圆弧管的圆外径为150mm，内弧管的圆内径为90mm。 沿着管子的中心线从径向对应于桥接部分的端部到外圆弧管的密封管端部分的距离测量的距离为11mm，沿着中心线测量的距离 从径向对应于桥接部的端部到内圆弧管的密封管端部的管的直径为6mm。
