本発明は、ハロゲン電球の製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for manufacturing a halogen light bulb.
従来例の構成とその問題点
臭素または塩素を用いたハロゲン電球を作る場合、ガラ
ス管内に酸素が残存すると短寿命となる。Conventional structure and problems When making a halogen light bulb using bromine or chlorine, if oxygen remains in the glass tube, the lifespan will be shortened.
従って、極力、電球内から酸素を取り除く必要がある。Therefore, it is necessary to remove oxygen from the bulb as much as possible.

いため、ガラス管内に酸素が残存することとなり、短寿
命が発生する原因となっていえ。Conventionally, in general, during the exhaust process, an inert gas containing a few percent of hydrogen was sealed inside the glass tube, the glass tube was heated from the outside with a burner, etc., and a filament was lit, and the heat was used to remove the metal inside the glass tube. A method was used to reduce the material. However, since such a method cannot sufficiently reduce the metal material inside the glass tube, oxygen remains inside the glass tube, causing a short life.
発明の目的
本発明はこのような問題を解決するもので、ガラス管内

ものである。Structure of the Invention According to the present invention, oxides of metal materials in the glass tube are reduced by diborane by filling the glass tube with a gas containing an inert gas and diborane during the evacuation process.
実施例の説明 以下本発明の一実施例を図面を参照して説明する。Description of examples An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 2 indicates a sealing portion, 3 a double-coiled tungsten filament provided inside the glass tube 1, 4 and 5 internal lead-in wires, and 6 a filament support wire. The filament support line 6 and the internal lead-in lines 4 and 6 are
Their bases are embedded in glass rod-shaped bodies by heat processing. 8 and 9 are molybdenum foils, and 1Q and 11 are external lead-in wires.

短寿命となったりする。In a halogen light bulb having such a configuration, a filament support wire 6 and internal lead-in wires 4 and 5 are attached to a glass rod-shaped body 7.
When embedding by heating processing, the filament support wire 6,
Internal lead-in wires 4 and 6 are often oxidized. The oxidation can be removed by chemical polishing or electrolytic polishing, but it is difficult to completely remove it. When a halogen bulb is completed by sealing, exhausting, and filling in a small amount of halogen compound along with an inert gas as a filler gas, this halogen bulb may cause early blackening or
It may have a short lifespan.
これらの問題を解決するためには、ガラス管内に残留す

金属材料を１０００℃以上の温度にする必要がある。し
かし、実際にはフィラメント以外の金属材料を１０００
℃以上に加熱することは困難である。As mentioned above, in general, during the evacuation process, the glass tube is filled with an inert gas containing several percent hydrogen, the glass tube is heated from the outside with a burner, etc., and a filament is lit. Methods have been used to reduce the materials, but in order to reduce the oxidized metal materials in the glass tube with hydrogen, it is necessary to bring the metal materials to a temperature of 1000° C. or higher. However, in reality, 1,000 metal materials other than filaments are used.
It is difficult to heat above ℃.
そこで、もっと低い温度で酸化を除去する方法忙ついて
検討を行った。Therefore, we have been busy investigating ways to remove oxidation at lower temperatures.

ほとんど分解しないだめ、酸化タングステンを蒸発させ

した。When heated, methylene bromide decomposes into carbon and hydrogen bromide. At higher temperatures, hydrogen bromide decomposes into hydrogen and bromine. When this bromine combines with tungsten oxide, it becomes tungsten oxybromide. Tungsten oxybromide has a low evaporation temperature and is easily evaporated by heat from the filament and heat from a burner, etc. from outside the glass tube, so it is thought that it is possible to exhaust it outside the glass tube during the exhaust process. Ta. However, when we actually investigated the prototype, we found that it did not work as expected. It was discovered that the cause of this was that the hydrogen bromide formed by decomposition of methylene bromide was hardly decomposed, and therefore not enough bromine was obtained to evaporate the tungsten oxide.
臭素の量を多くする目的で、封入ガス中の臭化メチレン

供することができなかった。When the amount of methylene bromide in the filler gas was increased to increase the amount of bromine, progress was made in the desired direction for evaporating tungsten oxide, but the carbon released when methylene bromide decomposed was It adhered to the filament, embrittled the filament, and caused blackening of the tube wall, making it impossible to put it to practical use.
臭素の炭化水素を用いず、不活性ガス中に臭素を封入し
た封入ガスの場合には、十分、酸化タングステンを蒸発
させることが可能であ−だが、排気機が臭素に侵食され
るだめ、実用に供することができなかった。If bromine is not used as a hydrocarbon, but bromine is sealed in an inert gas, it is possible to evaporate tungsten oxide sufficiently, but it is not practical because the exhaust equipment is corroded by bromine. could not be provided.
そこで、発明者は、臭素を用いずに酸化タングステンを
還元する方法について検討した。Therefore, the inventor investigated a method for reducing tungsten oxide without using bromine.

。Nitrogen,
We investigated using a trace amount of diborane together with an inert gas consisting of argon or a mixture thereof. When the filament inside the glass tube is lit, diborane easily decomposes due to the heat and becomes BH and hydrogen (Formula (I))

を還元することができる。In the case of hydrogen bromide, it is not possible to reduce tungsten oxide because the bond between bromine and hydrogen is strong, but a compound of boromine and hydrogen (BH) has a strong affinity for boromine and oxygen, so it cannot reduce hydrogen. The bond with tungsten is broken, and tungsten oxide is converted to boron oxide by removing oxygen from tungsten, so tungsten oxide can be reduced.

好ましくなかった。As a result of an experiment on the amount of diborane sealed in an inert gas, it was found that if the amount was less than 0.1 volume, the oxide inside the glass tube could not be removed, leading to early blackening and short life of halogen bulbs. did. However, if the volume is more than 2.5, the amount of boron diffused into the tungsten filament becomes too large, causing problems such as filament sag, which is undesirable.
