変形、断線事故の増加が予想されるものである。(Prior art and its problems) The halogen bulb (A) is a high-intensity incandescent bulb that uses a halogen cycle, but due to its features, it can be used as a headlight for automobiles, a light source for copiers, a light source for general lighting, etc. It is used. A halogen bulb (A) used as a light source of a copying machine is usually a straight tube type as shown in FIGS. 1 to 4, and a molybdenum metal rod (6) is used as a part of a filament (9) for adjusting the light quantity. ) Is inserted to short-circuit the light-emitting part (7).
And non-light emitting parts (5) are formed alternately, and further metal bars (6)
A support ring (8) was wound around the filament to support the filament (9) in the center of the glass tube (4). However, since the molybdenum metal rod (6) is solid, it has a larger weight than the filament (9). For example, when used in a copying machine, external vibration generated by reciprocating the halogen bulb (A) is generated. Filament (9)
Then, there was an accident in which the filament (9) was gradually displaced and the coil portion corresponding to the light emitting portion (7) was deformed, and the deformed portion caused a disconnection. At present, the machine cycle tends to be faster, and it is expected that the filament (9) will be deformed and the number of wire breakage accidents will increase.

Move while doing. When the irradiation of the original is completed, the halogen bulb (A) is turned off and the copying is completed. During this reciprocating movement of the halogen bulb (A), external vibration causes a halogen bulb (A)
However, since the support (3) which is arranged along with the non-light emitting part (5) of the filament (9) or which constitutes the non-light emitting part (5) is the metal foil (1), it is very lightweight. However, since it comes in contact with the inner wall surface of the glass tube at three points to provide a very durable support structure, it does not synchronize with the intense external vibration transmitted to the glass tube and does not cause axial swaying, so the filament light emitting part Since it does not expand or contract, it is not deformed, and the contact at three points does not cause rattling in directions other than the axial direction, so that external vibration hardly acts on the filament (9), and the filament (9) is deformed or broken. It can be used for a long time without accident.

Both ends of the filament (9) arranged in the glass tube (4) are welded to the molybdenum metal foil (1), and further the external lead rod (11) is welded from the molybdenum metal foil (1). It is led out to the outside, and a metal terminal (12) is butt-welded to its tip.
Further, an insulator (13) is adhered to the pinch seal portion (10) and holds the metal terminal (12). The filament (9) is a tightly wound coil-shaped light emitting part (7)
And non-light emitting portions (5) in which the filaments (9) are stretched are alternately formed, and the support (3) formed by the molybdenum metal foil (1) described later is formed on the non-light emitting portions (5). ) Is attached.

The metal foil (1) is made of molybdenum, has a rectangular shape, and is pressed into a shape in which both ends are folded and the central portion is expanded as shown in FIG. 2 (b). When viewed from the side, it has a V shape as shown in FIG. The support (3) is arranged along with the non-light emitting part (5) of the filament (9), and the filament attaching parts (2) at both ends of the support (3) are attached to the non-light emitting part (5) of the filament (9). The non-light emitting part (5) of the filament (9) is held by the metal foil (1) by welding or pressure welding. Then, as shown in FIG. 3, since the molybdenum metal foil (1) comes into contact with the three points on the inner surface of the glass tube (4) to support the filament (9 ) Comes to be located at the center of the glass tube (4).

にわたって使用する事が出来ると言う利点がある。(Effect of the present invention) As described above, the present invention forms a filament in which a light emitting portion of a filament is connected to a metal foil and a light emitting portion and a non-light emitting portion are alternately provided, and the filament is arranged in a glass tube. Since the metal foil is brought into contact with the inner peripheral surface of the glass tube and the metal foil is used as a support for the filament, the filament is supported in the glass tube with an extremely lightweight metal foil. , This support is the inner wall of the glass tube and 3
It abuts in places to provide a very sturdy support structure,
As a result, during the reciprocating movement of the halogen bulb, even if external vibration is transmitted to the halogen bulb, it does not synchronize with the vibration and does not cause axial sway, so the filament light emitting part does not expand or contract and is therefore not deformed. Since there is no rattling in a direction other than the axial direction due to the contact at the points, there is no such thing as the metal foil that is the support is displaced due to external vibration, and it is used for a long time without filament deformation or wire breakage accident. There is an advantage that you can do it.
尚、前述のように金属箔をサポートとして使用している
ので、ガラス管と接触する距離が従来のサポートリング
に比べて非常に長く、フィラメントに外部振動が加わっ
たときにより大きな抵抗となり、この点でもフィラメン
トの変形・断線防止に大きな威力を発揮する。Since the metal foil is used as a support as described above, the distance of contact with the glass tube is much longer than that of the conventional support ring, and the resistance becomes larger when external vibration is applied to the filament. However, it is very effective in preventing filament deformation and disconnection.
