ること、ができない不具合があった。(Prior art and its problems) In high-output incandescent light bulbs used for studio lighting, etc., the filament consists of multiple coil segments connected at connection parts, and these coil segments 1-
In many cases, the coil segments are installed parallel to each other between internal lead rods.In such mounts, it is necessary to install the coil segments under tension to prevent the coil segments from vibrating or coming into contact with each other during use. There is. Fourth
The figure shows a conventional example of such a mount, in which a pair of internal lead rods 4 are fixed by a pair of glass pieces 6 located above and below a filament 5, and a supporter 7 fixed by the glass pieces 6 is The filament 5 may be held by hooking the connecting portion 52 of the coil segment 51, or only the lower glass piece 6 may fix the internal lead rod 4, and the upper and lower glass pieces 6 may be fixed using supports. In any case, the distance between the upper and lower glass pieces 6 is determined when the upper and lower glass pieces 6 are formed by welding two glass rods sandwiching the internal lead rod 4 and the supporter 7. Tension must be applied to the coil segment 51 between the upper and lower glass pieces 6 whose positions are determined in advance, but since the hook portion of the supporter 7 is bent while being heat-treated after the glass piece 6 is formed, there are a number of steps. There was a problem that the tension increased and it was not possible to apply sufficient tension.
また、大出力の白熱電球は、封体の容積も大きくなり、
封体内部の大気を排気し、ハロゲンガスを含む不活性ガ
スのような所定の封入ガスを給入するために封体の頂部
の連設される排気管も内径の大きなものが使用される。In addition, high-output incandescent light bulbs have a large envelope volume,
The exhaust pipe connected to the top of the enclosure and having a large inner diameter is also used to exhaust the atmosphere inside the enclosure and supply a predetermined filler gas such as an inert gas containing halogen gas.
そして、排気管の内径が大きいと、チップオフしたとき

る。If the inner diameter of the exhaust pipe is large, when tip-off occurs, the wall thickness of that part will be stretched and become thinner, but the molten part with the thinner wall thickness will cave in due to the pressure difference between the inside and outside of the seal. There is. For this reason, it was necessary to use thick quartz glass for the exhaust pipe. Furthermore, if the internal diameter of the exhaust pipe is large, there is a problem in that when a support for holding the mount is inserted into the exhaust pipe to prevent the mount from moving, a fairly thick rod must be used as the support.

きるが、更に。That is, since the auxiliary exhaust pipe is welded to the upper glass piece, the auxiliary exhaust pipe is inserted into the exhaust pipe at the top of the seal, and is welded to the exhaust pipe, sufficient tension can be easily applied to the filament. And since we tip off the exhaust pipe, including the auxiliary exhaust pipe, we can hold the mount securely, but furthermore.
排気管は、補助排気管の肉厚を加算したものを使用した
のと同等になり、肉厚の大きなものを使用する必要がな
い。The exhaust pipe is equivalent to using one with the added thickness of the auxiliary exhaust pipe, so there is no need to use a thick one.

１に固定する。Next, as shown in FIG. 2, the mount is placed inside a split quartz glass enclosure 1. At this time, the auxiliary exhaust pipe 8 is placed at the top of the enclosure 1 with an outer diameter of 17 mmφ. is inserted into the exhaust pipe 12 of the exhaust pipe 12 and made to protrude from the exhaust pipe 12. Then, after pinch-sealing the portion of the sealing body 1 where the molybdenum foil 2 is located to form a crimp sealing portion 11, the auxiliary exhaust pipe 8 is welded to the exhaust pipe 12 while being pulled in the direction of the arrow. That is, the mount is fixed to the envelope 1 while being pulled in the vertical direction.

持することができる。In this way, by pulling the auxiliary exhaust pipe 8, the mount can be fixed to the envelope 1 while being pulled in the vertical direction, so that sufficient and uniform tension can be easily applied to the filament 5. Shaking of the coil segment 51 and contact accidents can be prevented. In addition, since the exhaust pipe 12 including the auxiliary exhaust pipe 8 is tipped off, even if the exhaust pipe 12 is thin, the thickness of the auxiliary exhaust pipe 8 is added, and the remaining part 13 of the exhaust pipe becomes thicker. , will not cave in when melted. Furthermore, the auxiliary exhaust pipe 8 perfectly fulfills the role of a holding rod, and the mount can be held securely without tilting.
以上説明したように、本発明によれば、大出力白熱電球
