本発明は、石英ガラス電球の封着金属に接続さ
れるフイラメントの支持体を改良したものに関す
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improved support for a filament connected to the sealing metal of a quartz glass light bulb.
従来の石英ガラス（高融点ガラス含む）を外囲
器として用いた電球、特にハロゲン電球は内部に
不活性ガス、ハロゲンガス及びコイル状フイラメ
ントを封有している。そして、石英ガラスの封着
部にはその熱膨張係数が近似したモリブデン箔が
封着金属として封着されている。
BACKGROUND ART Light bulbs using conventional quartz glass (including high melting point glass) as an envelope, especially halogen bulbs, have inert gas, halogen gas, and a coiled filament sealed inside. A molybdenum foil having a thermal expansion coefficient similar to that of the quartz glass is sealed as a sealing metal to the sealed portion of the quartz glass.
このモリブデン箔には内外に延びる導入線が溶
接固定されているのが普通である。この導入線の
うち内部導入線として上記コイル状フイラメント
の一部を延長して脚部を形成し、この脚部の端部
を上記モリブデン箔に固定するようにしたものが
ある。 Usually, lead-in wires extending inward and outward are welded and fixed to this molybdenum foil. Among these lead-in wires, there is one in which a part of the coiled filament is extended to form a leg portion as an internal lead-in wire, and the end portion of the leg portion is fixed to the molybdenum foil.
このフイラメントを脚部とする利点は第１図に
示すようにフイラメント１１と支持部分１２とが
一体化されているので直接封着金属１３に接続出
来ることである。ところが、電球を点灯した場合
にフイラメントと導入線部分との電流密度がほぼ
同一となるので、この支持部分も発光し易くな
る。すなわち、脚部が発光すると電力損失が大き
くなることに加えて封着部の温度が上昇し、封着
部に封着された封着金属の酸化を早めて短寿命と
なり易いという問題があつた。また、支持部分は
フイラメントと同一の直径であるので、低出力の
フイラメントの場合は径が細いので機械的強度が
弱く不安定となり易く、封着部付近から折れる危
険性が大である。 The advantage of using this filament as a leg is that, as shown in FIG. 1, the filament 11 and the supporting portion 12 are integrated, so that they can be directly connected to the sealing metal 13. However, when the light bulb is turned on, the current densities in the filament and the lead-in wire portion are approximately the same, so this support portion also tends to emit light. In other words, when the legs emit light, not only does power loss increase, but the temperature of the sealing part increases, which accelerates the oxidation of the sealing metal sealed to the sealing part, which tends to shorten the lifespan. . Furthermore, since the support portion has the same diameter as the filament, in the case of a low-output filament, the diameter is small, so the mechanical strength is weak and it tends to be unstable, and there is a high risk of it breaking near the sealed portion.
上記を改良する目的で第２図に示すようにコイ

持線２３の径を太くすることが出来て、支持体部

ここで問題となることは、封着金属と支持線との
接続に伴なう接触面である。これは第２図のＡ−
Ａ線の断面を第３図で示す通りほぼ線接触となる
ので、この局部的な接触面でのジユール熱による
発熱の発生が特にあり、これによつて封着金属２
２の過熱酸化が早期に発生すことがある。また、
この問題を解決するために封着金属との接合固定
部を扁平に加工したものが提案されている。この
場合は接触面積が増えて面接触に近くなるので、
ジユール熱の発生が少なくて都合がよい。しか
し、この支持線の加工に手間がかかり、作業性を
悪化させる原因となつてしまう。更にまた加工時
に塑性変形して機械的強度が低下し易く折れ易く
なる等の不都合が生ずることが多く信頼性に乏し
かつた。 In order to improve the above-described problem, various proposals have been made in which a metal support wire 23 is inserted between a coiled filament 21 and a sealing metal 22, as shown in FIG. The advantage of this is that the diameter of the support wire 23 can be increased regardless of the output of the filament, and the current density in the support portion can be reduced. However, the problem here is the contact surface associated with the connection between the sealing metal and the support wire. This is A- in Figure 2.
As the cross section of the A line is shown in Figure 3, there is almost a line contact, so heat generation due to Joule heat occurs particularly at this local contact surface, which causes the sealing metal 2
Overheated oxidation of No. 2 may occur early. Also,
In order to solve this problem, it has been proposed that the joint fixing part with the sealing metal is processed to be flat. In this case, the contact area increases and becomes close to surface contact, so
It is convenient because there is less generation of Joule fever. However, machining this support wire takes time and effort, which causes deterioration of workability. Furthermore, during processing, plastic deformation tends to occur, resulting in a decrease in mechanical strength and a tendency to break, resulting in poor reliability.
また、この支持線を更に太くすると封着金属と
の接合面積は多少拡大される。しかし封着部であ
るからこの支持線を太くすることは封着金属を薄
く箔状として熱膨張を石英ガラスに近似させた意
味がなくなつてしまい、封着部のクラツクの発生
が生じて信頼性が失なわれてしまうおそれが出て
来る。 Furthermore, if the support wire is made thicker, the area of contact with the sealing metal will be somewhat expanded. However, since it is a sealed part, making this support wire thicker would mean that the sealing metal was made thin and foil-like to approximate the thermal expansion of quartz glass, and cracks would occur in the sealed part, making it unreliable. There is a risk of losing one's sexuality.

A ring anchor 44 that is connected in series and supports a filament 42 and a shorting element 43 at appropriate locations is sealed. A support 45 (having three thin wires twisted around it) made of a strand wire (stranded wire) 46 is fitted and fixed to the end of the filament 42 . This fixing means is a strand wire (stranded wire)
46 may be inserted into the end of the coiled filament 42 and then pinched to crush and fix the filament coil, or a fixing material may be tightly wrapped over the coil. good. The other end of this support 45 is connected to a molybdenum foil that is a sealing metal 47, and is fixed together with the sealing metal 47 in a sealing part 49 that is sealed by pressing the end of the quartz glass bulb 41. has been done. Furthermore, an outer conductor 48 is fixed to this sealing metal 47. The connection relationship between the support body 45 and the sealing metal 47 is shown in enlarged scales in FIGS. 5a and 5b, where the strand wire 46 is welded and fixed to the surface of the sealing metal 47 while fitting very well therein. That is, in figure a, two strand wires 46 are fixed in contact with the molybdenum foil surface of the sealing metal 47 and have a sufficient contact surface, and in figure b, three strand wires 4b are all in contact with the molybdenum foil. Fixed. In this way, a quartz tube type light bulb is constructed.

分に緩和することが可能となる。 In the above light bulb according to the present invention, the sealing metal 4
7 and the support body 45 can have a sufficient contact area. That is, since the support body 45 is constituted by the strand wire 46, three wires are lined up in a plane, or at least two lines are lined up in a plane and sealed, as shown in FIGS. 5a and 5b. Since it comes into contact with the molybdenum foil, which is the deposited metal 47, the contact area between the two is significantly increased, making it possible to obtain sufficient current capacity and suppressing the generation of Joule heat. Moreover, since the support body 45 is a strand wire 46, when welding it with the sealing metal 47, each of them can be easily moved and become flat, and the heat generated by the wire can be kept to a minimum without special processing. Undesirable oxidation of the sealing metal 47 can be sufficiently alleviated.

どなくなる。 Since the filament element 42 and the support body 45 are bonded to each other, since the support body 45 is a strand wire 46, an uneven portion is formed that is perpendicular to the axial direction of the support body 45. Therefore, the coiled filament 42 and the uneven portion are coupled so as to intertwine with each other, so that the filament 42 and the support 4
It is easy to fix with 5, and accidents of slipping out are almost eliminated.

According to the present invention, the support for supporting the filament is constituted by a strand wire that is inserted and fitted into the coil of the filament, and the current density in this support is extremely small compared to the filament. Therefore, it prevents heat loss due to light emission from the support and Joule heat at the connection with the sealing metal, and
It was possible to provide a quartz glass light bulb in which the filament and the support can be securely fixed.
