Description

本発明は、ランプ本体を外的損傷から保護したり、ランプ本体の破裂・破壊による破片の飛散を防止したり、人体に有害な紫外放射を抑制・低減するため等の目的で、ランプ本体を収容する外管を取り付ける外管付きランプ及びその外管固定方法に関する。   The present invention protects the lamp body from external damage, prevents the lamp body from scattering due to rupture and destruction, and suppresses or reduces ultraviolet radiation harmful to the human body. The present invention relates to a lamp with an outer tube to which an outer tube to be accommodated is attached and a method for fixing the outer tube.

この種のランプとしては、発光管で成るランプ本体、あるいは発光管とこれを収容する気密管とで成るランプ本体が、ランプの外殻を形成する外管内に収容されたメタルハライドランプ等の金属蒸気放電ランプや、発光フィラメントとこれを収容する気密管とで成るランプ本体がランプの外殻を形成する外管内に収容されたハロゲンランプなどがある。
これらの外管付きランプは、その口金に、ランプ本体と該ランプ本体を収容する外管とを取り付ける取付ベースが形成され、該取付ベースに対して外管が耐熱性接着剤で固着されるものが一般的である。 As this type of lamp, a metal vapor such as a metal halide lamp or the like, in which a lamp body composed of an arc tube or a lamp body composed of an arc tube and an airtight tube accommodating the arc tube is accommodated in an outer tube forming the outer shell of the lamp. There are a discharge lamp, a halogen lamp in which a lamp body composed of a light emitting filament and an airtight tube for accommodating the light emitting filament is accommodated in an outer tube forming an outer shell of the lamp.
In these lamps with an outer tube, a mounting base for attaching a lamp main body and an outer tube for housing the lamp main body is formed on the base, and the outer tube is fixed to the mounting base with a heat-resistant adhesive. Is common.

そして、取付ベースは、前記外管の開口部を塞ぐ盤体と、ランプ本体を支持固定する支柱が形成されてなり、その支柱は、その周側面と、該周側面と対峙する前記外管の内周面との間に耐熱性接着剤を充填するギャップを形成する太さに形成されている。
このため、ランプ本体を支持させた支柱に外管を取付固定する場合は、支柱の周側面に前記ギャップに充填される接着剤を十分に盛り付けた後、外管で接着剤の周面を削ぎ落とすようにして、外管の開口部が取付ベースの盤体で塞がれるように装着することにより接着剤をギャップに充填させている。 The mounting base is formed with a disc body that closes the opening of the outer tube, and a column that supports and fixes the lamp body. The column includes a peripheral side surface of the outer tube that faces the peripheral side surface. It is formed in a thickness that forms a gap filled with a heat-resistant adhesive between the inner peripheral surface.
For this reason, when attaching and fixing the outer tube to the column supporting the lamp body, after the adhesive filled in the gap is sufficiently placed on the peripheral side surface of the column, the outer surface of the adhesive is shaved with the outer tube. The adhesive is filled in the gap by mounting so that the opening of the outer tube is closed by the base of the mounting base.

しかしながら、外管は透明であり、ギャップに充填された接着剤が外部から見えてしまうため、見栄えが悪く、商品価値を低下させていた。
特に、支柱に周側面に接着剤を盛り付ける場合、支柱側をランプ本体の長手方向に延びる中心軸を水平にしてこの回りに回転させながら、ノズル先端から搾り出した接着剤を支柱の周側面に巻き付けるようにして盛り付けている。
したがって、支柱側に盛り付けられた接着剤は、蛇がとぐろを巻いたような形状をしており、これをそのまま使用したり、こてで均したりしているが、いずれにしろ幾何学的なきれいな形状に盛り付けることはできない。 However, since the outer tube is transparent and the adhesive filled in the gap is visible from the outside, the appearance is not good and the commercial value is lowered.
In particular, when the adhesive is to be placed on the peripheral side of the column, the adhesive squeezed from the nozzle tip is wrapped around the column side while rotating around the column side with the central axis extending in the longitudinal direction of the lamp body. It is arranged like that.
Therefore, the adhesive placed on the side of the support is shaped like a snake wrapped around a spider, and it is used as it is or leveled with a trowel. It cannot be arranged in a beautiful shape.

このため、接着剤を隠すために、外管に不透明膜を形成した外管付きランプが提案されている。
この外管付きランプ５０は、図５に示すように、ランプ本体５１とこれを収容する外管５２が口金５３の取付ベース５４に取り付けられている。
そして、取付ベース５４に、外管５２の開口部５５を塞ぐ盤体５６と、ランプ本体５１を支持固定する支柱５７が形成されている。
支柱５７が、その周側面５７ａと、これに対峙する外管５２の内周面５２ａとの間に接着剤乃至充填材Ｓを充填するギャップ５８を形成する太さに形成され、支柱５７にランプ本体５１を支持させた状態で接着剤乃至充填材Ｓがギャップ５８に充填されて、外管５２が取付固定されている。
外管５２には、その長手方向に対して直交する方向から見てギャップ５８に充填された接着剤乃至充填材Ｓと対応する位置に、その接着剤乃至充填材Ｓが見えないように隠す不透明膜５９が形成されている。
実用新案登録第３１２４１８１号公報 For this reason, in order to hide the adhesive, a lamp with an outer tube in which an opaque film is formed on the outer tube has been proposed.
As shown in FIG. 5, the lamp 50 with the outer tube has a lamp body 51 and an outer tube 52 that accommodates the lamp body 51 attached to an attachment base 54 of a base 53.
The mounting base 54 is formed with a board 56 that closes the opening 55 of the outer tube 52, and a column 57 that supports and fixes the lamp body 51.
The support column 57 is formed to a thickness that forms a gap 58 for filling the adhesive or filler S between the peripheral side surface 57a and the inner peripheral surface 52a of the outer tube 52 facing the support column 57a. An adhesive or filler S is filled in the gap 58 in a state where the main body 51 is supported, and the outer tube 52 is fixedly attached.
The outer tube 52 is opaque so that the adhesive or filler S is hidden from view at a position corresponding to the adhesive or filler S filled in the gap 58 when viewed from the direction orthogonal to the longitudinal direction. A film 59 is formed.
Utility Model Registration No. 3124181

この場合、不透明膜５９は、図５（ａ）に示すように外管５２の内周面５２ａに形成する場合と、図５（ｂ）に示すように外管５２の内周面に形成する場合が考えられるが、外管５２の根元部分はランプの点灯により高温に晒され、消灯により室温まで低下するため、その温度変化が激しい。
したがって、不透明膜５９は、耐熱性材料を用いて温度変化に晒されても外管表面から剥れない程度の接着強度（高投錨性）で形成しなければならず、例えば、アルミナ−シリカ系の耐熱塗料に外管を浸漬してその内周面又は外周面に塗布し、これを高温で焼き付けている。
すなわち、耐熱塗料を塗布する工程だけでなく、さらに、焼付工程が必要となる。
そして、ランプや外管の製造ライン中に製膜用の焼成炉を新たに設置する場合は、設備費が嵩むだけでなく、既存の設備を移動させたりして設置スペースを確保しなければならないという面倒がある。既存の焼成炉を利用できる場合であっても、ラインの搬送路を見直すなどの作業が必要になる。
また、いずれの場合も、焼付工程が増設されることから省エネの社会的要請に反し、製造コストが嵩み、生産効率が低下するという問題があった。 In this case, the opaque film 59 is formed on the inner peripheral surface 52a of the outer tube 52 as shown in FIG. 5A and on the inner peripheral surface of the outer tube 52 as shown in FIG. 5B. In some cases, the root portion of the outer tube 52 is exposed to a high temperature when the lamp is turned on, and decreases to room temperature when the lamp is turned off.
Therefore, the opaque film 59 must be formed with an adhesive strength (high throwing property) that does not peel off from the outer tube surface even when exposed to temperature changes using a heat resistant material. The outer tube is immersed in the heat-resistant paint and applied to the inner peripheral surface or the outer peripheral surface, and this is baked at a high temperature.
That is, not only the process of applying the heat resistant paint but also a baking process is required.
And when installing a film-forming baking furnace in the lamp or outer tube production line, not only will the equipment cost increase, but the existing equipment must be moved to secure the installation space. There is a trouble. Even when an existing firing furnace can be used, work such as reviewing the conveyance path of the line is required.
Moreover, in any case, since the baking process is increased, there is a problem that the manufacturing cost is increased and the production efficiency is lowered against the social demand for energy saving.

さらに、外管内周面５２ａに不透明膜５９を形成した場合に剥離すると、ギャップに充填された接着剤乃至充填材Ｓの外管に対する投錨性が消失するため、外管５２が脱落するおそれさえある。
また、外管外周面５２ｂに不透明膜５９を形成した場合に、そのような温度変化等の使用条件に耐えきれずに剥離すると、外管５２内に盛り付けた接着剤乃至充填材Ｓが露呈するだけでなく、剥離痕が見苦しく、剥離した塗膜が周囲に飛散するという問題も生ずる。 Furthermore, if the opaque film 59 is formed on the inner peripheral surface 52a of the outer tube, peeling off of the adhesive or filler S filled in the gap with respect to the outer tube may cause the outer tube 52 to drop off. .
Further, when the opaque film 59 is formed on the outer peripheral surface 52b of the outer tube, the adhesive or the filler S placed in the outer tube 52 is exposed if the opaque film 59 is peeled off without being able to withstand such use conditions as temperature change. In addition, the peeling marks are unsightly, and there arises a problem that the peeled coating is scattered around.

そこで本発明は、外管に別途不透明な膜を形成することなく、支柱部分に盛り付けられた接着剤乃至充填材を外部から見えないようにして、見栄えを良くし、商品価値を向上させることを技術的課題としている。   Therefore, the present invention is to improve the appearance and improve the commercial value by making the adhesive or filler placed on the support column invisible from the outside without forming a separate opaque film on the outer tube. It is a technical issue.

上記課題を解決するために、請求項１の発明は、ランプ本体と該ランプ本体を収容する外管が口金の取付ベースに取り付けられ、該取付ベースに、前記外管の開口部を塞ぐ盤体と、ランプ本体を支持固定する支柱が形成されてなり、前記支柱が、その周側面と、該周側面と対峙する前記外管の内周面との間に接着剤乃至充填材を充填するギャップを形成する太さに形成され、当該支柱にランプ本体を支持させた状態で前記外管を取付固定する外管付きランプの外管固定方法において、前記支柱の周側面に、前記ギャップに充填される接着剤乃至充填材を盛り付け、前記外管内周面には、前記支柱側に盛り付けられた接着剤乃至充填材の取付ベースからその盛付頂点に至るまでの盛付高さより大きな付着幅で、取付ベース側から外管内周面に設定した見切線に至るまで予め接着剤乃至充填材を塗り付けておき、当該外管の開口部が前記盤体で塞がれるように外管を取付ベースに当接させ、前記接着剤乃至充填材をギャップに充填した後に固化させることを特徴としている。
この場合に、請求項２では、前記支柱の周側面と前記外管の内周面に、夫々前記ギャップに面する凹部又は凸部を形成しておき、前記ギャップに充填した前記接着剤乃至充填剤によって、前記外管と前記支柱とを接合するジョイントを成形する。 In order to solve the above-mentioned problems, according to the invention of claim 1, a lamp body and an outer tube that accommodates the lamp body are attached to a mounting base of a base, and the mounting base closes an opening of the outer tube. And a column for supporting and fixing the lamp body, and the column is filled with an adhesive or a filler between the peripheral side surface and the inner peripheral surface of the outer tube facing the peripheral side surface. In the outer tube fixing method for a lamp with an outer tube, the outer tube is mounted and fixed in a state where the lamp body is supported by the column, and the gap is filled in the peripheral side surface of the column. Adhesive or filling material, and on the inner peripheral surface of the outer pipe, with an adhesion width larger than the height of the mounting from the mounting base of the adhesive or filling material arranged on the column side to the top of the mounting, Installed on the inner peripheral surface of the outer pipe from the mounting base side The adhesive or filler is applied in advance until reaching the parting line, and the outer pipe is brought into contact with the mounting base so that the opening of the outer pipe is closed by the disc body, and the adhesive or filler It is characterized by solidifying after filling the gap.
In this case, according to the second aspect of the present invention, a concave portion or a convex portion facing the gap is formed on the peripheral side surface of the support column and the inner peripheral surface of the outer tube, respectively, and the adhesive or filling filled in the gap. agent by, for forming the shape of a joint that joins the said and the outer tube strut.

請求項１の発明によれば、支柱の周側面に、前記ギャップに充填される接着剤乃至充填材を盛り付け、外管内周面には、支柱側に盛り付けられた接着剤乃至充填材の取付ベースからその盛付頂点に至るまでの盛付高さより大きな付着幅で、取付ベース側から外管内周面に設定した見切線に至るまで予め接着剤乃至充填材を塗り付けておく。
そして、外管の開口部が前記盤体で塞がれるように外管を取付ベースに当接させ、前記接着剤乃至充填材をギャップに充填した後に固化させる。
これにより、外管内周面に付着した接着剤乃至充填材の取付ベースから先端側見切線に至るまでの付着幅が、前記支柱側に盛り付けられた接着剤乃至充填材の取付ベースからその盛付頂点に至るまでの盛付高さより大きく選定された外管付ランプが製造される。 According to the first aspect of the present invention, the adhesive or filler filled in the gap is provided on the peripheral side surface of the support column, and the adhesive or filler mounting base provided on the support column side is provided on the inner peripheral surface of the outer tube. The adhesive or filler is applied in advance from the mounting base side to the parting line set on the inner peripheral surface of the outer tube with an adhesion width larger than the height of the height from the height to the height of the height.
Then, the outer tube is brought into contact with the mounting base so that the opening of the outer tube is closed by the disc body, and the adhesive or filler is filled in the gap and then solidified.
This ensures that the attachment width from the mounting base of the adhesive or filler adhering to the outer tube circumference up to the front end side parting line, the mounting base of the adhesive or filler is dished on the post side thereof A lamp with an outer tube that is selected to be larger than the height of the leading up to the top of the serving is manufactured.

この外管付ランプによれば、外管内周面の取り付けベース側から見切線までに付着している接着剤の付着幅が、支柱側に盛り付けられた接着剤の盛付高さより大きいので、外管外部からその長手方向に対して直交する方向から見ると、外管内周面に付着している接着剤は見えるが、そのさらに内側の支柱側に盛り付けられた接着剤は隠されることになる。
このとき、外管に耐熱性の不透明膜を別途形成する必要がないので、不透明膜形成工程に必要な過大な設備投資が不要であり、また、不透明膜剥離による不具合を生ずることもない。 According to this lamp with outer tube, since the adhesion width of the adhesive adhering from the mounting base side to the parting line on the inner peripheral surface of the outer tube is larger than the height of the adhesive deposited on the column side, When viewed from the direction perpendicular to the longitudinal direction from the outside of the tube, the adhesive attached to the inner peripheral surface of the outer tube can be seen, but the adhesive placed on the inner column side is hidden.
At this time, since it is not necessary to separately form a heat-resistant opaque film on the outer tube, an excessive capital investment necessary for the opaque film forming process is unnecessary, and there is no problem caused by peeling of the opaque film.

さらに、請求項２に記載されているように、支柱の周側面と外管の内周面に、夫々前記ギャップに面する凹部又は凸部を形成しておき、前記ギャップに充填した前記接着剤乃至充填剤によって、前記外管と前記支柱とを接合するジョイントを成形すれば、外管は、接着剤乃至充填剤の接着力によらず、該接着剤乃至充填剤で成形されたジョイントによって口金の取付ベースに取り付けられるので、接着剤乃至充填剤が経時劣化によって接着力を喪失しても、口金の取付ベースから脱落するおそれがない。 Furthermore, as described in claim 2, the concave portion or the convex portion facing the gap is formed on the peripheral side surface of the support column and the inner peripheral surface of the outer tube, respectively, and the adhesive filled in the gap or the filler, if formed form a joint for joining said and the outer tube strut, the outer tube, by not relying on the adhesive strength of the adhesive or filler, molded in the adhesive or filler joint Since it is attached to the attachment base of the base, even if the adhesive or the filler loses the adhesive force due to deterioration with time, there is no possibility of dropping off from the attachment base of the base.

本発明は、外管に別途不透明な膜を形成することなく、支柱部分に盛り付けられた接着剤乃至充填材を外部から見えないようにして、見栄えを良くし、商品価値を向上させるという目的を達成するために、前記支柱の周側面に、前記ギャップに充填される接着剤乃至充填材を盛り付け、前記外管内周面には、前記支柱側に盛り付けられた接着剤乃至充填材の取付ベースからその盛付頂点に至るまでの盛付高さより大きな付着幅で、取付ベース側から外管内周面に設定した見切線に至るまで予め接着剤乃至充填材を塗り付けておき、当該外管の開口部が前記盤体で塞がれるように外管を取付ベースに当接させ、前記接着剤乃至充填材をギャップに充填した後に固化させた。   An object of the present invention is to improve the appearance and improve the commercial value by making the adhesive or filler placed on the support column invisible from the outside without forming a separate opaque film on the outer tube. To achieve this, an adhesive or filler filled in the gap is provided on the peripheral side surface of the support column, and an adhesive or filler mounting base provided on the support column side is provided on the inner peripheral surface of the outer tube. Adhesive or filler is applied in advance from the mounting base side to the parting line set on the inner peripheral surface of the outer pipe with an adhesion width larger than the height of the leading up to the peak of the opening, and the opening of the outer pipe The outer tube was brought into contact with the mounting base so that the portion was closed by the disc body, and the adhesive or filler was filled in the gap and then solidified.

図１は本発明に係る外管付ランプを示す一部切欠斜視説明図、図２は本発明に係る外管固定方法を示す説明図、図３は外管内への接着剤塗布方法を示す説明図、図4は外管装着工程を示す説明図である。   FIG. 1 is a partially cutaway perspective explanatory view showing a lamp with an outer tube according to the present invention, FIG. 2 is an explanatory diagram showing an outer tube fixing method according to the present invention, and FIG. 3 is an explanatory diagram showing an adhesive application method in the outer tube. FIG. 4 and FIG. 4 are explanatory views showing the outer tube mounting step.

本例の外管付きランプＬは、ランプ本体１がセラミック製の発光管２とこれを収容する石英ガラス製の気密管３とで成るメタルハライドランプであって、その口金４に、ランプ本体１と該ランプ本体を収容する硬質ガラス製又は石英ガラス製の外管５とを取り付ける取付ベース６が形成されている。
なお、本例では、外管５が、外径２２.０ｍｍ、肉厚１.５ｍｍの先丸直管の中間部に半径１３.０ｍｍの球面が形成されるように最大外径２６.０ｍｍに膨らませた形状をしており、ランプ本体１の気密管３は外径１５.０ｍｍ、肉厚１.２ｍｍの直管状に形成されている。 The lamp L with an outer tube of this example is a metal halide lamp in which a lamp body 1 is composed of a ceramic arc tube 2 and a quartz glass hermetic tube 3 that accommodates the arc tube 2. A mounting base 6 is formed to which an outer tube 5 made of hard glass or quartz glass that accommodates the lamp body is attached.
In this example, the outer tube 5 has a maximum outer diameter of 26.0 mm so that a spherical surface with a radius of 13.0 mm is formed in the middle portion of the rounded straight tube having an outer diameter of 22.0 mm and a wall thickness of 1.5 mm. The airtight tube 3 of the lamp body 1 is formed in a straight tube shape having an outer diameter of 15.0 mm and a wall thickness of 1.2 mm.

口金４の取付ベース６は、外管５の開口部７を塞ぐ盤体８に、ランプ本体１を支持固定する支柱９が形成され、その全体がセラミック等の磁器体で形成された構成となっている。また、支柱９は、その先端から軸方向に沿って、ランプ本体１を構成する気密管３のピンチシール部１０を差し込んで耐熱性の接着剤で固定するためのスリット１１が形成されている。   The mounting base 6 of the base 4 has a structure in which a column 9 for supporting and fixing the lamp body 1 is formed on a plate body 8 that closes the opening 7 of the outer tube 5, and the whole is formed of a ceramic body such as ceramic. ing. Moreover, the support | pillar 9 is formed with the slit 11 for inserting the pinch seal part 10 of the airtight tube 3 which comprises the lamp | ramp main body 1 along the axial direction from the front-end | tip, and fixing with a heat resistant adhesive agent.

そして、支柱９の周側面と、該周側面と対峙する外管５の内周面との間に、耐熱性の接着剤乃至充填剤を充填するためのギャップ１２が形成されると共に、互いに対峙する支柱９の周側面と外管５の内周面に、夫々ギャップ１２に面する凹部１３と凸部１４が形成され、そのギャップ１２に充填した耐熱性の接着剤乃至充填剤Ｓによって、外管５と支柱９とを接合するジョイントＪが成形されている。
なお、支柱９の凹部１３は、支柱９の周方向に延びる凹溝で形成され、外管５の凸部１４は、外管５の開口端を口金４の取付ベース６に形成された盤体８の周壁部８ａの内側に嵌め付けるためにその外管５の開口端を縮径させて口細形状にする加工によって形成されたもので、外管５の内側に突出する環状の凸部を成している。本例の場合、開口端の外径が１８.０ｍｍに縮径されて、凸部１４が形成されている。 A gap 12 for filling a heat-resistant adhesive or filler is formed between the peripheral side surface of the support column 9 and the inner peripheral surface of the outer tube 5 that faces the peripheral side surface. A concave portion 13 and a convex portion 14 that face the gap 12 are formed on the peripheral side surface of the supporting column 9 and the inner peripheral surface of the outer tube 5, respectively, and the heat-resistant adhesive or filler S filled in the gap 12 It is the joint J GaNaru shape joining the tube 5 and the support 9.
The concave portion 13 of the support column 9 is formed by a concave groove extending in the circumferential direction of the support column 9, and the convex portion 14 of the outer tube 5 is a board body in which the opening end of the outer tube 5 is formed on the mounting base 6 of the base 4. 8 is formed by a process of reducing the diameter of the open end of the outer tube 5 so as to be fitted into the inside of the peripheral wall portion 8a. It is made. In the case of this example, the outer diameter of the opening end is reduced to 18.0 mm, and the convex portion 14 is formed.

耐熱性の接着剤乃至充填剤Ｓは、例えば、１００〜３００℃程度の低温で硬化させることができ、１０００〜２０００℃の高温に耐えることができるスミセラム（朝日化学工業株式会社の商品名）等の低温硬化型のペースト状無機接着剤乃至充填剤で成る。
そして、この接着剤乃至充填剤Ｓは、外管内周面５ａに対して取付ベース６から先端側見切線２１に至る付着幅Ｗｓで付着され、支柱９側で取付ベース６からその盛付頂点２２に至るまでの盛付高さＨｓに盛り付けられ、外管内周面５ａ側の付着幅Ｗｓが支柱９側の盛り付け高さＨｓより大きく選定されたジョイントＪが形成されている。 For example, the heat-resistant adhesive or filler S can be cured at a low temperature of about 100 to 300 ° C. and can withstand a high temperature of 1000 to 2000 ° C. (trade name of Asahi Chemical Industry Co., Ltd.) The low-temperature curing type paste-like inorganic adhesive or filler.
The adhesive or filler S is attached to the outer peripheral surface 5a of the outer tube with an attachment width Ws from the attachment base 6 to the tip-side parting line 21, and from the attachment base 6 on the column 9 side, the peak apex 22 thereof. The joint J is formed so as to have a height Hs that reaches the height of the inner wall 5a, and the adhesion width Ws on the inner peripheral surface 5a side of the outer tube is selected to be larger than the height Hs on the side of the support column 9.

これにより、外管５の長手方向に対して直交する方向から見たときに、盛付高さＨｓで支柱９側に盛り付けられている接着剤乃至充填材Ｓの様子は、外管内周面５ａに付着幅Ｗｓで付着している接着剤乃至充填材Ｓにより隠されて見ることができず、したがって、外管付ランプの見栄えが良く商品価値が向上する。
すなわち、外管５の外側からギャップ１２に充填された接着剤乃至充填材Ｓが見えてしまうが、接着剤乃至充填材Ｓのうち、支柱９側に盛り付けられた見栄えの悪い部分を、外管内周面５ａに付着している部分で隠すことができる。
したがって、外管５の内周面又は外周面に別途不透明膜を形成する必要がなく、ランプＬや外管５の製造ラインに膜形成工程を組み込む必要もない。 Thereby, when seen from the direction orthogonal to the longitudinal direction of the outer tube 5, the state of the adhesive or the filling material S placed on the support column 9 side at the height Hs of the outer tube is shown in FIG. Therefore, it is not possible to see it hidden by the adhesive or the filler S adhering with the adhering width Ws. Therefore, the appearance of the lamp with the outer tube is good and the commercial value is improved.
That is, the adhesive or filler S filled in the gap 12 can be seen from the outside of the outer tube 5, but the unsightly portion of the adhesive or filler S arranged on the support column 9 side is removed from the inner tube. It can be hidden by the part adhering to the peripheral surface 5a.
Therefore, it is not necessary to separately form an opaque film on the inner peripheral surface or outer peripheral surface of the outer tube 5, and it is not necessary to incorporate a film forming process in the production line of the lamp L or the outer tube 5.

図２及び図３はこのような外管付ランプの外管固定方法を示す具体例である。
外管５を口金４の取付ベース６に固定する場合、まず、図２（ａ）に示すように、支柱９に形成されたスリット１１にランプ本体１の気密管３のピンチシール部１０を差し込んでおく。
次いで、図２（ｂ）に示すように、支柱９の周側面に、ギャップ１２に充填される接着剤乃至充填材Ｓを盛り付け、外管５には、その内周面５ａに設定した見切線２１まで接着剤乃至充填材Ｓを付着させておく。
このとき、支柱９に盛り付けられた接着剤乃至充填材Ｓは、取付ベース６からその盛付頂点２２に至るまでの盛付高さがＨｓであり、外管内周面５ａに塗り付けられた接着剤乃至充填材Ｓは、開口部７から見切線２１に至るまでの付着幅がＷｓであり、付着幅Ｗｓが盛付高さＨｓより大きくなるように見切線２１の位置が設定されている。
したがって、この外管５を口金４の取付ベース６に取り付ければ、図２（ｃ）に示すように、外管内周面５ａに付着している接着剤乃至充填材Ｓにより、支柱９に盛り付けられた接着剤乃至充填材Ｓが隠されることになる。 2 and 3 are specific examples showing a method of fixing the outer tube of such a lamp with an outer tube.
When fixing the outer tube 5 to the mounting base 6 of the base 4, first, as shown in FIG. 2A, the pinch seal portion 10 of the hermetic tube 3 of the lamp body 1 is inserted into the slit 11 formed in the column 9. Leave in.
Next, as shown in FIG. 2 (b), an adhesive or filler S filled in the gap 12 is arranged on the peripheral side surface of the support column 9, and the parting line set on the inner peripheral surface 5 a of the outer tube 5. Adhesive or filler S is allowed to adhere to 21.
At this time, the adhesive or filler S deposited on the support column 9 has a height of Hs from the mounting base 6 to the peak apex 22 and is applied to the outer peripheral surface 5a of the outer tube. In the agent or filler S, the adhesion width from the opening 7 to the parting line 21 is Ws, and the position of the parting line 21 is set so that the adhesion width Ws is larger than the height Hs.
Therefore, when the outer tube 5 is attached to the attachment base 6 of the base 4, as shown in FIG. 2C, the outer tube 5 is placed on the support column 9 by the adhesive or filler S attached to the outer peripheral surface 5 a of the outer tube. The adhesive or filler S is hidden.

図３（ａ）〜（ｃ）は、開口部７から見切線２１に至るまで付着幅Ｗｓで外管内周面５ａに接着剤乃至充材Ｓを塗り付ける方法の一例を示す。
塗布装置３１は、図３（ａ）に示すように、タンク３２に貯留された液状接着剤乃至充填材Ｓの液面より高い位置に、外管５の開口部７を嵌め込む凹部３３を備えた治具３４が形成され、凹部３３の周囲には外管５を気密に支持するパッキン３５が嵌め付けられている。
タンク３２と凹部３３とはその底面側で流路３６を介して連通されると共に、前記治具３４には、外管５を凹部３３に嵌め込んだ状態で外管５内の空気を出し入れする通気管３７が設けられている。 3A to 3C show an example of a method of applying an adhesive or a filler S to the inner peripheral surface 5a of the outer tube with an adhesion width Ws from the opening 7 to the parting line 21. FIG.
As shown in FIG. 3A, the coating device 31 includes a recess 33 into which the opening 7 of the outer tube 5 is fitted at a position higher than the liquid adhesive or filler S stored in the tank 32. A jig 34 is formed, and a packing 35 for airtightly supporting the outer tube 5 is fitted around the recess 33.
The tank 32 and the recess 33 communicate with each other via a flow path 36 on the bottom side thereof, and the air in the outer tube 5 is taken into and out of the jig 34 with the outer tube 5 fitted into the recess 33. A vent pipe 37 is provided.

これによれば、図３（ｂ）に示すように、治具３４の凹部３３に外管５の開口部７をはめ込み、通気管３７を介して外管５の空気を抜くと、タンク３２から流路３６を通って外管５内に接着剤乃至充填材Ｓが流入する。
そして、その液面が予め設定した見切線２１に達したところで、通気管３７を大気に開放することにより、あるいは、外管５内に空気を送り込むことにより、外管５内に流入していた接着剤乃至充填材Ｓは、図３（ｃ）に示すように、外管内周面５ａに付着した部分を残してタンク２内に還流し、これにより、外管内周面５ａには、開口部７から見切線２１に至るまで所定の付着幅Ｗｓで塗料が塗り付けられることになる。
なお、接着剤乃至充填財Ｓの粘性が高く、通気管３７を介して外管５の空気を抜いただけでは外管５内に流入しない場合は、接着剤乃至充填財Ｓを加圧して外管５内に強制的に流入させるようにすればよい。 According to this, as shown in FIG. 3 (b), when the opening 7 of the outer tube 5 is fitted into the recess 33 of the jig 34 and the air in the outer tube 5 is removed through the vent tube 37, The adhesive or filler S flows into the outer tube 5 through the flow path 36.
And when the liquid level reached the preset parting line 21, the air flowed into the outer pipe 5 by opening the vent pipe 37 to the atmosphere or by sending air into the outer pipe 5. As shown in FIG. 3C, the adhesive or the filler S flows back into the tank 2 while leaving a portion attached to the inner peripheral surface 5a of the outer tube, and thereby, an opening is formed in the inner peripheral surface 5a of the outer tube. The paint is applied with a predetermined adhesion width Ws from 7 to the parting line 21.
If the adhesive or filling material S has a high viscosity and does not flow into the outer tube 5 just by removing the air from the outer tube 5 through the vent pipe 37, the adhesive or filling material S is pressurized to the outer tube. 5 may be forced to flow in.

図４は外管を装着する工程を示す説明図であって、内周面５ａに接着剤乃至充填材Ｓを付着させた外管５を取付ベース６に固定する際は、図４（ａ）〜（ｂ）に示すように外管５を徐々に下ろして行き、図４（ｃ）に示すように支柱９に盛り付けられた接着剤乃至充填材Ｓの外周部を縮径された外管５の開口部７で削ぎ落としながら、図４（ｄ）に示すように外管５の開口端を口金４の取付ベース６に形成された盤体８の周壁部８ａの内側に嵌め付け、外管５の外周部にはみ出した接着剤乃至充填材Ｓをふき取る。   FIG. 4 is an explanatory view showing a process of mounting the outer tube. When fixing the outer tube 5 with the adhesive or filler S attached to the inner peripheral surface 5a to the mounting base 6, FIG. The outer tube 5 is gradually lowered as shown in FIG. 4 (b), and the outer diameter of the outer periphery of the adhesive or filler S placed on the support column 9 is reduced as shown in FIG. 4 (c). 4 (d), the opening end of the outer tube 5 is fitted inside the peripheral wall 8a of the plate body 8 formed on the mounting base 6 of the base 4 as shown in FIG. The adhesive or filler S that protrudes from the outer periphery of 5 is wiped off.

これにより、支柱９の周側面と外管５の内周面５ａとに塗り分けられていた接着剤乃至充填剤Ｓ、Ｓが相互に粘着し合って一体化し、図４（ｄ）に示すように、支柱９の周側面と外管５の内周面との間に形成されるギャップ１２に接着剤乃至充填剤Ｓが充填された状態となる。
この状態で、接着剤乃至充填剤Ｓを低温加熱して硬化させると、その接着剤乃至充填剤Ｓが外管５と支柱９とを接合するジョイントＪとなり、該ジョイントＪによって、外管５が口金４の取付ベース６に取り付けられると同時に、外管５が取付ベース６から脱落することが阻止される。 As a result, the adhesives or fillers S and S applied separately to the peripheral side surface of the support column 9 and the inner peripheral surface 5a of the outer tube 5 adhere to each other and are integrated, as shown in FIG. In addition, the gap 12 formed between the peripheral side surface of the support column 9 and the inner peripheral surface of the outer tube 5 is filled with an adhesive or a filler S.
In this state, when the adhesive or filler S is heated and cured at a low temperature, the adhesive or filler S becomes a joint J that joins the outer tube 5 and the support column 9. At the same time that the outer tube 5 is attached to the attachment base 6 of the base 4, the outer tube 5 is prevented from falling off the attachment base 6.

ジョイントＪは、外管内周面５ａに対して取付ベース６から先端側見切線２１に至る接着剤乃至充填剤Ｓの付着幅Ｗｓが、支柱９側における取付ベース６からその盛付頂点２２に至るまでの接着剤乃至充填剤Ｓの盛付高さＨｓより大きく選定されているので、外管５の長手方向に対して直交する方向からランプＬを見たときに、盛付高さＨｓで支柱９側に盛り付けられている接着剤乃至充填材Ｓの様子は、外管内周面５ａに付着幅Ｗｓで付着している接着剤乃至充填材Ｓにより隠されて見ることができず、したがって、外管付ランプＬの見栄えが良く商品価値を向上させることができる。   In the joint J, the adhesion width Ws of the adhesive or filler S extending from the mounting base 6 to the tip-side parting line 21 with respect to the outer peripheral surface 5a of the outer tube reaches from the mounting base 6 on the support column 9 side to the summit vertex 22 thereof. Is selected to be larger than the height Hs of the adhesive or filler S up to when the lamp L is viewed from the direction perpendicular to the longitudinal direction of the outer tube 5, the support column has the height Hs of the height. The state of the adhesive or filler S placed on the 9 side cannot be seen hidden by the adhesive or filler S adhering to the outer peripheral surface 5a of the outer tube with the adhering width Ws. The appearance of the tube lamp L is good and the product value can be improved.
