本発明は透光性セラミクス管を発光管バルブと
する金属蒸気放電灯の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for manufacturing a metal vapor discharge lamp using a translucent ceramic tube as an arc tube bulb.
透光性セラミクス管を発光管バルブとして使用
した金属蒸気放電灯たとえば高圧ナトリウムラン

る。
Metal vapor discharge lamps, such as high-pressure sodium lamps, which use translucent ceramic tubes as arc tube bulbs are known as lamps with excellent luminous efficiency.

発光管の最冷部温度を高く保つことが必要とな
る。 Recently, from the viewpoint of energy conservation, there has been a demand for improvements in this type of lamps as indoor light sources by making them smaller and lowering their wattage. For example, if a high-pressure sodium lamp is to be used as an indoor light source, it must be recommended to improve its color rendering properties, and this requires keeping the temperature of the coldest part of the arc tube high.
ところで、透光性セラミクス管は石英ガラス管

定の発光金属（発光物質）および始動用希ガスを
封入しなければならないが、この排気封止には以
下の方法が採用されている。 By the way, unlike quartz glass tubes, it is difficult to thermally process translucent ceramic tubes, so the tube end opening is sealed with a separate closing body. Niobium caps and ceramic disks are known as the closing body, and are hermetically bonded to a translucent ceramic tube with glass solder or metal solder. The interior of such an arc tube must be evacuated and filled with a predetermined luminescent metal (luminescent substance) and starting rare gas, and the following method is adopted for sealing the exhaust gas.
すなわちその１つは、閉塞体の中央部にニオブ
チユーブなどの排気管を気密に貫通させ、この排
気管の内端に電極を取り付けたもので、排気およ
び封入物の投入はこの排気管を通じて行われる。 One of them is to airtightly pass through an exhaust pipe made of niobium tube or the like through the center of the closing body, and an electrode is attached to the inner end of this exhaust pipe, and the exhaust and the injection of the inclusions are carried out through this exhaust pipe. .
このものは排気および封入物の封入が完了する
と、排気管の外端部を封止（チツプオフ）してい
る。しかしながらこの封止端は閉塞体の外方に突
出する先端が最冷部となり、この最冷部の温度上
昇が困難になる。 In this case, the outer end of the exhaust pipe is sealed (tip-off) after exhaustion and filling are completed. However, in this sealed end, the outwardly projecting tip of the closure body becomes the coldest part, and it becomes difficult to raise the temperature of this coldest part.
したがつてこのものは演色性の改善にはたいし
て役に立たず、小形、低ワツト化を図つて室内用
光源とするには演色性の面で不向きとなる。 Therefore, this product is not very useful for improving color rendering properties, and is not suitable for use as an indoor light source due to its size and low wattage.
このような方法に代つてたとえば特公昭49−
12980号公報に示された排気封止方法が知られて
いる。 Instead of this method, for example,
An exhaust gas sealing method disclosed in Japanese Patent No. 12980 is known.

ガスと同一のガスで置換し、セラミクス管の上端
開口部より発光金属を投下し、しかるのちこの上
端開口部を閉塞体により封止するものである。 In this method, a ceramic tube whose one end has been sealed with a closing body is placed vertically in a bell gear with the closed end side facing downward, and the inside of the bell gear is replaced with the same gas as the starting rare gas. A luminescent metal is dropped through the opening, and then the upper opening is sealed with a closing body.
この方法は排気管を使用しないことからチツプ
レスタイプと称されており、点灯中に最冷部が管
内の閉塞体近傍、つまり管端部に形成されるので
チツプオフタイプに比べて最冷部の温度を高温に
保持でき、演色性の改善に有効となる。 This method is called the tip-press type because it does not use an exhaust pipe, and the coldest part is formed near the blocker in the pipe, that is, at the end of the pipe, so compared to the tip-off type, the coldest part is formed during lighting. The temperature can be maintained at a high temperature, which is effective in improving color rendering properties.
しかしながら上記チツプレスタイプにおいては
排気・封止工程中に以下のごとき問題を生じる。 However, in the chip press type described above, the following problems occur during the evacuation and sealing steps.
つまり、ベルジヤ内においてセラミクス管の上

に小形、低ワツトランプでは熱源が発光物質に近
いので輻射熱により発光物質の飛散消失が著し
い。 That is, in order to seal the upper end of the ceramic tube within the bell gear, the sealing location is heated to near the melting point of the solder. During this heating, the luminescent material that has already been put into the ceramic tube is evaporated and scattered by the radiant heat and escapes to the outside of the ceramic tube, making it impossible to obtain the desired luminescent characteristics. Large, high-output lamps have long tubes, and when the top opening is heated, it is difficult for the heat to reach the luminescent material deposited at the bottom. Particularly in small, low-wattage lamps with tube lengths of 70 to 60 mm or less, the heat source is close to the luminescent material, so the luminescent material is significantly scattered and lost due to radiant heat.

ンプの製造においては、封入物の消失を少なくす
ることが大きな課題となつていた。 Furthermore, in small, low-wattage lamps, the amount of luminescent material filled in is small, and slight changes in this amount have a large effect on lamp characteristics, so when manufacturing this type of lamp, it is necessary to minimize the loss of the filled material. This had become a major issue.

The present invention has been made to address the above-mentioned drawbacks.
It is an object of the present invention to provide a method for manufacturing a metal vapor discharge lamp, which can prevent an enclosed luminescent substance from scattering and disappearing outside the arc tube during manufacture of the arc tube, thereby obtaining a specific stable metal vapor discharge lamp.

In the process of sealing the end of the chit press type arc tube, the present invention provides a reservoir for the sealed luminescent substance in advance at the center of the inner surface of one of the closing bodies to be sealed first, and then By allowing the luminescent substance to be sealed from the bulb to accumulate, the radiant heat generated when the other end opening of the arc tube bulb is then heated and sealed via the sealing material with the other closing body is absorbed by the luminescent substance. This is designed to reduce the influence and prevent the luminescent material from evaporating and scattering.

Hermetically sealed using a sealing material such as glass solder 3 whose main components are Al 2 O 3 and CaO,
Electrodes 5A and 5B are supported at one end of lead-in wires 4A and 4B made of a heat-resistant metal, such as niobium, which airtightly penetrate the center of each of the closing bodies 2A and 2B via a sealing material 3 such as glass solder. There is.

ことが好ましい。 Next, an embodiment of a method for manufacturing such an arc tube will be described. First, as shown in FIG.
A is supported and sealed via a glass solder 3 by a closure body 2A having a concave recess 6 for the enclosed luminescent substance in the center of the inner surface. Next, if a granular amalgam 7 made of luminous substances, sodium Na and mercury Hg, is dropped from the unsealed opening at the other end of the arc tube bulb 1, the amalgam 7 will move as shown by the arrow into the closure body 2A. It falls upward and collects in a concave reservoir 6 provided at the center of its inner surface. This step is preferably carried out in an inert gas to prevent deterioration of the amalgam.

て加熱封止する。 Next, the sealed amalgam 7 is placed in a vertical position as shown in Fig. 2 in a closed container such as a bell gear, and the inside of the closed container is replaced with a starting rare gas, for example (Ne-Ar) mixed gas. , the above (Ne-Ar) mixed gas is introduced into the arc tube bulb 1. After passing through each of these steps, the opening at the other end of the unsealed side of the arc tube bulb 1 is heat-sealed via the sealing material 3 by the other closing body 2B supporting the electrode 5B.

る。 At this time, the radiant heat generated in the heat sealing process tries to reach the amalgam 7 sealed in the previous process, but since the pool 6 of the amalgam 7 is located below the electrode 5A, this electrode 5A It acts as a shield for radiant heat, so the radiant heat hardly reaches the amalgam 7, and the amalgam 7 is prevented from disappearing outside the arc tube bulb 1 due to evaporation and scattering.
なお、発光物質の溜り部６の最大径は電極５Ａ
の最大径よりも小さくなるように形成することが
最も好ましい。 Note that the maximum diameter of the luminescent substance reservoir 6 is the same as that of the electrode 5A.
It is most preferable to form it so that it is smaller than the maximum diameter of.

である。 Furthermore, if the amalgam 7 is brought into contact with the electrode shaft or the electrode lead-in wire, and the part of the lead-in wire 4A outside the arc tube is cooled (not shown), the encapsulating material has better thermal conductivity than ceramics. Since the lamp is cooled by the wire, the disappearance of the inclusions is further suppressed, and a lamp with good and stable characteristics can be obtained.

The same parts as those shown in the second figure are denoted by the same reference numerals, and the description thereof will be omitted. In this example, the entire inner surface of one of the closing bodies 2A forming the luminescent material reservoir 6 is shaped like a mortar, and the luminescent material is collected in the center thereof. With such a shape, the luminescent substance to be dropped and sealed can be easily accumulated at the base of the electrode 5A, that is, at the position directly below, and radiant heat can be avoided using the electrode 5A as a shield.
