重管構造のランプでは組み立てに手間がかかっていた。However, in the triple tube structure lamp, it is very difficult to match the tube axis of the outer tube, the tube axis of the inner tube and the tube axis of the arc tube, and the workability is not good. . This will be described in detail with reference to FIG. An outer lead rod extending from the arc tube is connected to an inner lead rod arranged inside the outer tube so that the tube axis of the arc tube and the tube axis of the outer tube are aligned with each other. Next, the inner tube was connected to the inner lead rod supporting the arc tube by a supporting member so that the tube axis of the inner tube coincided with the tube axis of the outer tube. In other words, since the tube axes of the arc tube and the inner tube are made to coincide with the tube axis of the outer tube independently, the tube axis of the arc tube and the tube axis of the outer tube are misaligned, or the tube axes of the arc tube and the outer tube are not aligned. However, there was a problem that the tube axis of the inner tube was misaligned.
In other words, it was difficult to achieve coaxiality. In addition, it takes time to assemble the lamp having such a triple tube structure.
