トリウムランプが提案されている。Conventional Technology As we enter an era of full-scale energy conservation, the development and commercialization of compact high-intensity discharge lamps to replace low-wattage incandescent light bulbs is actively underway. In particular, in order to use high-pressure sodium lamps and metal halide lamps as the main light source for indoor lighting, lamps with efficiency and high color rendering properties comparable to the luminous flux level of 100-150W class incandescent bulbs are used. Attempts are being made to develop and commercialize compact OW class high pressure sodium lamps and metal halide lamps. For example, a new compact high-pressure sodium lamp has been proposed in Japanese Patent Application Laid-Open No. 61-4554.

があった。Problems to be Solved by the Invention In such a small high-pressure sodium lamp, the getter holding member 18 is bent in order to be able to insert the wide getter holding member 18 into the outer tube 9 having a small inner diameter. The width is narrowed. However, when the getter holding member 18 subjected to such a bending process is welded to the lead wire 7, the mounting angle of the getter holding member 18 with respect to the lead wire 7 (the central axis of the lead wire 7 and the getter holding member 18 The angle between the getter material filled in the central hole and the surface tends to vary.The getter temperature is determined by heat conduction and heat radiation of the arc tube 1, so if the mounting angle of the getter holding member 18 varies, There was a problem in that the getter temperature varied, the getter did not operate properly, and the lamp life characteristics varied.
