本発明は、両端を封止した外管内に発光管を収容してな
る２重管構造の高圧放電灯に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a high-pressure discharge lamp having a double tube structure in which an arc tube is housed in an outer tube whose both ends are sealed.
（従来の技術）
一般に高圧放電灯は、外管内に発光管を収容して２重管
構造をなしている。(Prior Art) Generally, a high-pressure discharge lamp has a double-tube structure in which an arc tube is housed within an outer bulb.
従来の場合、外管形状はＢＴまたはＢ型などのように片

であり、このため外管か大形になるなどの不具合がある
。In the conventional case, the outer tube has a single-end structure in which only one end is sealed, such as a BT or B type. However, such a structure requires a frame-shaped support, a stem, etc. to surround the arc tube and support the arc tube inside the outer tube, which causes problems such as the outer tube being large.
このため、最近、第５図に示すような両口金形の２重管
構造の放電灯が開発されている。For this reason, recently, a double-cap double tube structure discharge lamp as shown in FIG. 5 has been developed.

部導入線４．４に接続されている。The arc tube 10 is constructed by closing both ends of a bulb 11 made of a translucent alumina tube or the like with disks 12 and 12 made of ceramic or niobium. An electrode 13.13 is attached to the occluding disk 12.12. Attached to these closing discs 12.12 are electrical conductors 14.14 made of niobium tubes connected to the electrodes 13.13. These conductors 14.14 are connected to the internal lead-in line 4.4 via a spring element 15.15 and a support 16.16.

溶接されている。The spring member 15.15 is made of a wire made of niobium, tantalum, or the like, and the center portion of the wire spring member 15.15 is welded to the conductor 14, and both ends of the wire spring member 15.15 are formed into a substantially U-shaped support. It is welded to both ends of 16. This support 16 is welded to the internal lead-in line 4.4.

るので、外管１の径を従来のＢＴまたはＢ型などに比べ
て、２０〜４０％も小形化することができ、使用分野が
広くなり、普及度が拡大する。In such a configuration, the arc tube 10 is housed in the outer tube 1 which is sealed at both ends, and both ends of the arc tube 10 are connected to the sealing portions 2.
2, the diameter of the outer tube 1 can be reduced by 20 to 40% compared to the conventional BT or B type, making it easy to use. The field will expand and the degree of penetration will expand.
ところで、石英チューブからなる外管１内に、透光性ア
ルミナなどのようなセラミックチューブからなる発光管
１０を収容して両端部を固定すると、石英チューブとア
ルミナチューブの熱膨脹差が発生し、点滅のたびに伸縮
差が生じる。By the way, when the arc tube 10 made of a ceramic tube such as translucent alumina is housed in the outer tube 1 made of a quartz tube and both ends are fixed, a difference in thermal expansion occurs between the quartz tube and the alumina tube, causing the blinking. A difference in expansion and contraction occurs each time.
これを吸収するため、発光管１０と内部導入線４．４の
間にばね部材１５．１５を設けである。In order to absorb this, a spring member 15.15 is provided between the arc tube 10 and the internal lead-in line 4.4.
このばね部材１５．１５は、アルミナチューブからなる
発光管１０が外管１に対して熱膨脹差を生じると弾性的

２や発光管１０の破損を防止している。This spring member 15.15 expands elastically when the arc tube 10 made of an alumina tube causes a difference in thermal expansion with respect to the outer tube 1, thereby absorbing the difference in expansion and contraction, and the sealing portion 2 of the outer tube 1 and This prevents the arc tube 10 from being damaged.

０およびＭｏ箔２の位置を外管１の中心軸上に保持し、
Ｍｏ箔２は正しく伸びている必要がある。That is, when inserting the arc tube 10 into the outer tube 1 and crushing and sealing the end of the outer tube 1, as shown in FIG.
0 and the Mo foil 2 are held on the central axis of the outer tube 1,
Mo foil 2 needs to be stretched correctly.

There is also a risk that the wire spring member 15 and the internal lead-in wire 4 may be bent or cut.

（実施例）
以下本発明について、第１図および第２図に示す第１の
実施例にもとづき説明する。(Example) The present invention will be described below based on a first example shown in FIGS. 1 and 2.
この実施例においては、第５図に示す従来の構造を改造

てその説明を省略する。This embodiment is a modification of the conventional structure shown in FIG. 5, and the same members as those in the conventional structure are designated by the same numbers and their explanations will be omitted.
本実施例で従来と異なる点は、内部導入線４．４の内端
部にワイヤリングからなるホルダー２０．２０を取着し
たことである。This embodiment differs from the conventional one in that a holder 20.20 made of a wire ring is attached to the inner end of the internal lead-in wire 4.4.

に当接可能となっている。The holder 20 is made of, for example, SUS material, and one end is welded to the inner end of the internal lead-in wire 4.4, and the other end extends in the radial direction and is shaped like a ring along the inner surface of the outer tube 1. The link portion extends and can come into contact with the inner surface of the outer tube 1.
つまり、リング部はやつと外管１に挿入可能な程度に、
この外管の内径より僅かに小さく形成されており、この
リング部は弾性変形可能となっている。In other words, the ring part can be easily inserted into the outer tube 1.
The ring portion is formed to be slightly smaller than the inner diameter of the outer tube, and is elastically deformable.

サポート１６の傾きを防止し、Ｍｏ箔３の座屈を防止す
るとともに、発光管１０の傾きを防止する。According to such a configuration, as shown in FIG. 7, when the mount is sealed to the outer tube 1, the holder 20 is attached to the outer tube.
Because it hits the inner surface of the inner lead-in wire 4 and prevents eccentricity of the inner lead-in wire 4,
This prevents the support 16 from tilting, prevents the Mo foil 3 from buckling, and prevents the arc tube 10 from tilting.

。Furthermore, even if a difference in expansion and contraction occurs between the outer tube 1 made of a quartz tube and the arc tube 10 made of a translucent alumina tube due to differences in thermal expansion during use of the lamp configured in this way, these differences in expansion and contraction will be compensated by the spring member. 15 is elastically deformed and absorbed, thereby preventing damage to the sealing portion 2 of the outer bulb 1 and the arc tube 10.

持される。Even if vibration or impact is applied, the fluctuation in the axial direction of the arc tube 10 is absorbed by the elastic deformation of the spring member 15,
In addition, the holder 20 attached to the internal lead-in wire 4 hits the inner surface of the outer tube 1 to prevent eccentric movement of the radial direction. Therefore, the arc tube 10 is reliably held on the central axis of the outer tube 1.

字形ばね部材３０を用いた点である。The difference between this embodiment and the first embodiment is that the wire spring member 15 and the support [6] of the first embodiment are replaced by U
This is because the shape spring member 30 is used.
すなわち、Ｕ字形ばね部材３０はニオビウムなどからな

止される。Even in this configuration, even if the outer tube 1 made of a quartz tube and the arc tube 10 made of a translucent alumina tube expand or contract due to differences in thermal expansion, these differences in expansion and contraction are caused by the elastic deformation of the U-shaped spring member 30. It can be absorbed by
Therefore, damage to the sealing portion 2 of the outer tube 1 and the arc tube 10 is prevented.

Therefore, the arc tube 10 is reliably held on the central axis of the outer tube 1.
