−・ロデン化物高圧放電ランプの製造方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides two
The electrode system is hermetically melted or squeezed into the core, and the polarization system is disposed within the discharge vessel. A packing wheel defined by a melting part or pressing part, and a current supply conductor protruding from inside the melting part or pressing part in the direction of the longitudinal axis of the lamp. The present invention relates to a method of manufacturing a double-ended high-pressure discharge lamp. In particular, the invention relates to a method for manufacturing metal-lodenide high-pressure discharge lamps with a power output of up to 50 W.

容器の中へ入れ、最後にポンプ管を熔かし切る。Speaking of metal halide high-pressure discharge lamps with an output of 50W, these lamps have recently been widely used for lighting in public facilities and in truck headlights, but until now these lamps were made by first closing one end of a quartz tube with both ends open. , then the quartz glass is assembled in the shape of a diolive at the location of the future discharge vessel, and then in the next working step the initially closed tube ends are opened again and the pump tube is inserted into the central wall of the discharge vessel. Put it on. After each electrode system is inserted into the open tube end and melted, the filling material and the filling gas are introduced into the discharge vessel using the pump tube, and finally the pump tube is melted out.

このランプを光学系に所定の導入をする際の欠点となる
。This conventional manufacturing method, which is expensive and requires concentration, has additional drawbacks as follows. This is achieved by attaching the pump pipe to a very small discharge vessel (its length is only about 7.511L, and its diameter is only about 5.511L) and sealing it by fusing. ``Inhomogeneity occurs, which negatively affects the cold spot temperature and thus also the light color of the lamp, and on the other hand also irreproducibly scatters the light emitted from the lamp.'' This is a drawback when implementing this lamp into an optical system.
この発明の課題は、このような問題となっているランプ
を簡単に製造することであシ、その際不拘−な材質配分
が放電容器に生じないようにして、前記欠点を排除する
ことにある。The object of the present invention is to eliminate the above-mentioned drawbacks by simply manufacturing a lamp that has caused such problems, and in doing so without causing any unrestricted material distribution in the discharge vessel. .

ポンプ管つきランプの場合よｐもよシ多く均一化する。Since the process of filling and sealing the discharge vessel is carried out in the highly clean atmosphere of the glove box, contamination by foreign gases such as hydrogen, oxygen, and water vapor is minimized. By heating the tube, which is still open, in the glove box, the particle density in this area is reduced. Because of this (after sealed melting with plasma birch in the glove box and after cooling of the discharge vessel) a certain low pressure is obtained in its interior, combined with a temperature drop below approximately 100 °C, so that the second squeezing part can be removed from the glove box. It becomes possible to manufacture the product outside the POC. The use of the manufacturing method according to the invention significantly reduces the manufacturing time and simplifies the entire manufacturing process. Since there is no longer a pump tube in this discharge vessel, there are no differences in wall thickness or other types of non-uniformities. The light emission of the lamp is therefore much more uniform than in conventional lamps with pump tubes.

明・暗境界の配置が重要となるものに用いられる。This lamp therefore becomes suitable for implementation in optical systems, for example in truck headlights, where fairly precise adjustment and placement of the bright/dark boundary are important.
以下、この発明を５つの図面金剛いてより詳しく説明す

Two constriction parts 4 and 5 are provided at the center and spaced from each other at a predetermined distance (FIG. 1b). During heating and shaping, nitrogen N2 is passed through the tube 1 from one side at a rate of 10-e violet per hour. By providing the crimping parts 4, 5, the discharge vessel 6 (FIG. 1C) of the old rice is accurately cut to a length of about 7.511 mm. The tightening portion 4 has a smaller inner diameter than the tightening portion 5. As a result, a gas damming part P for the nitrogen flow N2 is generated in the future PA heating area of the discharge vessel 6 between the two wire clamping parts 4.5, and as a result, this heating area swells to some extent, resembling an olive fruit. It becomes an oval shape. The shape of the olive fruit has an outer diameter of about 5.5 cm.

The electrode system consists of a tungsten electrode 1, a molybdenum packing wheel 8, and a molybdenum current supply conductor 9. The electrode 7 is provided with a ball 10 at its end located within the discharge vessel 6 .

座標での電極１のセンタリングも自動的に達成される。The current supply conductor 9 is bent in a zigzag manner in the y = -z plane 29, the angle α being only the bent current supply conductor 9! ' - The deviation from the Z plane is less than 45°, in particular about 20° to 60°. The height h, which is the value, is equal to the value of the turning point 11 of the bent current supply conductor 9.
It is offset from the Z plane and is larger than half of the inner diameter d of the tube 1. In reality, it has been found that the relationship corresponding to h + 0.55 d is appropriate. Patsukin wheel 8 is x-z
y- of the in-plane and therefore bent current supply conductor 9
They are arranged perpendicular to the z-plane. The support of such a shaped electrode system in the tube body 1a takes place by pressing the current supply conductor 9 against the inner wall of the tube while holding down the folds or folding points 11. Once adjusted into position on the tube, the inner tube wall continues to support the electrode system until final fixation. At least six turning points 11 are provided to ensure reliable support of the current supply conductor 9 to the inner wall of the tube 1.0.
is provided on each supply conductor 9. The supply conductor 9 thus formed is centered on the axis of the tube 1a body. This allows the packing wheel BOX in the discharge vessel 6 to
Centering of the electrode 1 in the coordinates is also achieved automatically.

特に示していない。As shown in FIG. 6, the first pressing section 12 is then made. For this purpose, the tube 1 is heated in the region of the packing wheel 8 to a temperature suitable for forming, which is approximately 2200 DEG C. or higher. At the same time, argon fluid is allowed to flow through the entire formed tube 1. When the pressing temperature is reached, the first pressing section 12 is formed. First of all, the compressed portions adjacent to the small diameter crimped portion 4 are stacked against each other. The manufacture of this compressor is not specifically shown in the figures since it is a process well known to those skilled in the field of lamp manufacturing.

ハロゲン化物１４と水銀１５の蒸発を防止する。FIG. 4a shows the one-sided squeeze lamp of FIG. 6 which is placed in the glove box 13. Next, the filling material (this is metal) is first poured into the discharge vessel 6, which has become cold again.
It consists of 14 Rodenvilles and 15 mercury beads. ) and a second electrode system (Figure 4b). This filling material penetrates into the discharge vessel 6 through the still open constriction 5 which has a relatively large diameter. As mentioned earlier in the preparation of the first compressing section 12, this electrode system is self-supporting and adjusted at a predetermined mounting position for this electrode system, so that the electrode 7 is discharged. The spacing between the spheres 10 of the picture electrode 7 arranged inside the container 6 is kept precisely at its predetermined value. The open tube 1 is then heated with a heating device. This results in a local density reduction in the heated area. Then quartz W1'
Inside the glove box 13, the open end is sealed and melted using a plasma burner 16 or a laser (FIG. 4C), so that only the melted tip 17 (FIG. 4D) remains. When the prefabricated lamp gold is cooled, the reduced local stiffness inside the discharge vessel creates a filling pressure that is approximately 500 mbar lower than the ambient atmospheric pressure. I took it out of the glove box 13 again.
As already explained in the case of the first compression section 12, the second
The area around the packing wheel 8 of the electrode system is approximately 220
The second compressed portion 18 (FIG. 5) is completely formed by heating to a pressing temperature of 0° C. and caulking the second electrode system. During this heating and squeezing step, the region of the discharge vessel 6 is kept cooled to below 100° C. with the cooled nitrogen gas to prevent evaporation of the metal halide 14 and mercury 15.
