Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ハロゲン電球に関する。The present invention relates to a halogen bulb.
ハロゲン電球は、一般に光源あるいは熱源として種々
の分野に用いられている。Halogen bulbs are generally used as light sources or heat sources in various fields.
例えば複写機の露光用光源としては、配光分布の制御
が容易であることから、従来、ガラス製管型封体内に、
発光部と非発光部とを有するフィラメントを管軸に沿っ
て延びるよう配設してなるハロゲン電球が好適に用いら
れている。For example, as an exposure light source for copiers, since the distribution of light distribution is easy to control, conventionally, a glass tube-shaped envelope
A halogen lamp in which a filament having a light-emitting portion and a non-light-emitting portion is disposed so as to extend along a tube axis is suitably used.
しかして、ハロゲン電球においては、ハロゲンサイク
ルを遂行させるために、ガラス製管型封体内に、従来、
不活性ガスと、ハロゲンを含むガスとが封入されてい
る。However, in the halogen lamp, in order to perform the halogen cycle, conventionally, in a glass tube-shaped envelope,
An inert gas and a gas containing halogen are sealed.
複写機の露光用光源として用いられるハロゲン電球に
おいては、露光のたびごとに点灯・消灯が繰返して行わ
れるので、ガラス製管型封体の管壁の温度が低下しやす
い、そのため比較的低温時においても円滑にハロゲンサ
イクルが遂行されるような活性なハロゲンを用いること
が好ましい。斯かるハロゲンとしては塩基が好適であ
る。Halogen bulbs used as light sources for copier exposure are repeatedly turned on and off for each exposure, so that the temperature of the tube wall of the glass tube-type envelope tends to decrease. In this case, it is preferable to use an active halogen so that the halogen cycle can be smoothly performed. Bases are preferred as such halogens.
しかし、塩素は、臭素等に比して活性が高いため、反
面、フィラメントの低温部分と反応しやすく、その結果
断線等によりハロゲン電球の使用寿命を短縮する問題が
ある。However, chlorine has a higher activity than bromine or the like, and on the other hand, easily reacts with the low-temperature portion of the filament. As a result, there is a problem that the service life of the halogen bulb is shortened due to disconnection or the like.
一方、ガラス製管型封体の酸素を除去する目的で当該
封体内にはゲッターが封入されるが、斯かるゲッターと
しては、従来、シラン、ハロゲン化シランが知られてい
る。これらの化合物によれば、封体内の酸素が二酸化ケ
イ素となって管壁やフィラメントの低温部等に付着する
ことによって封体内の酸素が除去される。On the other hand, a getter is sealed in the glass tube-type sealed body for the purpose of removing oxygen, and silane and halogenated silane are conventionally known as such getters. According to these compounds, oxygen in the envelope is removed by converting the oxygen in the envelope into silicon dioxide and adhering to the tube wall or the low-temperature portion of the filament.
しかし、シランおよびハロゲン化シランは反応性が高
く、例えばシラン（SiH4）はハロゲンと爆発的に反応す
るため、これをハロゲンと混合して使用すると危険であ
る問題がある。また、ハロゲン化シラン（SiCl4,SiHC
l3,SiH2Cl2,SiHBr3,CH3SiCl3）等は水蒸気と反応してハ
ロゲン化水素が生成するため配管設備を腐蝕する問題が
ある。However, silanes and halogenated silanes are highly reactive. For example, silane (SiH 4 ) explosively reacts with halogens, and thus there is a problem that it is dangerous to use them in a mixture with halogens. In addition, halogenated silanes (SiCl 4 , SiHC
l 3 , SiH 2 Cl 2 , SiHBr 3 , CH 3 SiCl 3 ) have a problem of corroding piping equipment because they react with steam to generate hydrogen halide.
本発明者等が以上の如き事情に基づいて鋭意研究を重
ねた結果、封入ガスの組合せおよび配合量を特定の範囲
に限定することにより、黒化現象の防止および長寿命化
と、封入ガスの導入のための配管設備の腐蝕防止とを一
挙に達成できることを見出し、本発明を完成したもので
ある。The inventors of the present invention have conducted intensive studies based on the above circumstances, and as a result, by limiting the combination and blending amount of the filling gas to a specific range, it is possible to prevent the blackening phenomenon and extend the life, and to increase the filling gas. The present inventors have found that corrosion prevention of piping equipment for introduction can be achieved at once, and have completed the present invention.
本発明の目的は、黒化現象の抑制および長寿命化を図
ることができ、しかも封入ガスの導入のための配管設備
の腐蝕を防止することができるハロゲン電球を提供する
ことにある。An object of the present invention is to provide a halogen lamp capable of suppressing the blackening phenomenon and prolonging the life thereof, and preventing corrosion of piping equipment for introducing a sealed gas.
上記目的を達成するため、本発明は、発光部と非発光
部とを有するフィラメントを備えてなるガラス製管型封
体内に、不活性ガスと、モノメチルシランと、塩素と、
水素とが封入されてなるハロゲン電球において、下記条
件〜の満足することを特徴とする。In order to achieve the above object, the present invention provides, in a glass tubular envelope including a filament having a light emitting portion and a non-light emitting portion, an inert gas, monomethylsilane, and chlorine,
In a halogen lamp filled with hydrogen, the following conditions (1) to (4) are satisfied.
条件；塩素の封入量が前記ガラス製管型封体の内容積
1cc当り0.14〜1.4×10-6グラム原子であること。Condition: The amount of chlorine enclosed is the inner volume of the glass tube-shaped envelope.
0.14 to 1.4 × 10 -6 gram atoms per cc.
条件；モノメチルシランの封入量が前記ガラス製管型
封体の内容積1cc当り0.012〜0.16μmolであること。Conditions: The amount of monomethylsilane to be enclosed is 0.012 to 0.16 μmol per 1 cc of the inner volume of the glass tubular envelope.
条件；塩素および水素の封入量が、両者のグラム原子
数の比（Cl/H）で0.9〜3.0であること。Conditions: The amount of chlorine and hydrogen charged is 0.9 to 3.0 in terms of the ratio of the number of gram atoms of both (Cl / H).
ガラス製管型封体内に、不活性ガスと、モノメチルシ

定の配合割合で封入したので、点灯・消灯を繰返して行
うときのように封体の管壁の温度が比較的低い場合に
も、活性な塩素により円滑なハロゲンサイクルが遂行さ
れ、また塩素の低温時における活性が水素により好適に
抑制されるためフィラメントの構成材料の塩素による劣
化が防止され、そして好適な量のモノメチルシランによ
り良好なゲッター作用が発揮されるため酸化劣化を十分
に防止することができる。Since the inert gas, monomethylsilane, chlorine, and hydrogen are sealed in the glass tube-type enclosure at a specific mixing ratio that satisfies the above conditions (1) and (2), sealing is performed as if lighting and extinguishing were repeatedly performed. Even when the temperature of the body tube wall is relatively low, a smooth halogen cycle is performed by active chlorine, and the activity of chlorine at a low temperature is suitably suppressed by hydrogen, so that the constituent material of the filament is deteriorated by chlorine. And a suitable amount of monomethylsilane exerts a good getter effect, so that oxidative deterioration can be sufficiently prevented.
そして、モノメチルシランは塩素との反応性が低いの
で封入ガスの導入のための配管設備を腐蝕する原因とな
る物質が生成せず、封入ガスの導入を安定に行うことが
できる。Since monomethylsilane has low reactivity with chlorine, a substance causing corrosion of piping equipment for introducing the sealed gas is not generated, and the sealed gas can be introduced stably.
以下、本発明の実施例を説明する。 Hereinafter, embodiments of the present invention will be described.
第１図は本発明の一実施例を示す説明図である。 FIG. 1 is an explanatory view showing one embodiment of the present invention.
10はガラス製管型封体、20はフィラメント、30は内部
リード、40は気密シール用金属箔、50は外部リード、60
は封入ガスの導入管（破線で示す）61を封止して形成し
たチップである。10 is a glass envelope, 20 is a filament, 30 is an inner lead, 40 is a metal foil for hermetic sealing, 50 is an outer lead, 60
Is a chip formed by sealing an inlet tube 61 (shown by a broken line) for filling gas.
フィラメント20は、例えばコイル状のタングステン線
よりなる発光部21と、隣接する発光部21と21とを連結す
る例えばモリブデン棒よりなる非発光部22とよりなる。The filament 20 includes a light emitting portion 21 made of, for example, a coil-shaped tungsten wire, and a non-light emitting portion 22 made of, for example, a molybdenum rod connecting the adjacent light emitting portions 21 to 21.
しかして、本発明においては、ガラス製管型封体10内
には、不活性ガスと、モノメチルシランと、塩素と、水
素とを上記条件〜を満足するように封入する。Thus, in the present invention, an inert gas, monomethylsilane, chlorine, and hydrogen are sealed in the glass tube-shaped sealing body 10 so as to satisfy the above conditions (1) and (2).
前記条件において、塩素の封入量が過小のときには

る。Under the above conditions, when the amount of chlorine is too small, it is difficult to perform a smooth halogen cycle especially at a low temperature, so that the blackening phenomenon occurs early. On the other hand, when the amount of enclosed chlorine is excessive, the light emitting portion 21 or the non-light emitting portion 22 of the filament 20 is deteriorated by chlorine, so that the service life is shortened.

色するため透光性が悪くなる。Under the above conditions, when the amount of monomethylsilane is too small, the getter function is insufficient and the amount of oxygen in the enclosure becomes too large, so that the service life is shortened due to oxidative deterioration. On the other hand, when the filling amount of monomethylsilane is excessive, the minimum necessary oxygen is also taken out in the envelope, making it difficult to perform a smooth halogen cycle, causing an early blackening phenomenon, and SiO or SiO 2 on the tube wall. Is adhered and the color is changed to white or yellow, so that the light transmittance is deteriorated.

I do. On the other hand, when the ratio of the number of gram atoms (Cl / H) is excessively large, the effect of suppressing the activity of chlorine by hydrogen is insufficient.
In addition, the non-light emitting portion 22 is deteriorated, and the service life is shortened.
不活性ガスとして、例えばアルゴン、クリプトン等を
用いることができる。この不活性ガスの封入量は特に限

I do. After the introduction of the introduction gas is completed, the introduction pipe 61 is sealed.
