Abstract

PURPOSE:To prevent a filament of a luminous part from being deformed and disconnected by sticking metallic foils on an inner peripheral surface of a glass tube and using them as supports of the filament of the luminous part. CONSTITUTION:A plurality of molybdenum metallic foils 1 are stuck on an inner peripheral surface of a glass tube 4 made of quartz glass in a halogen electric lamp A, and the foils 1 on both the ends are buried respectively into pinch sealed parts 10. Filaments 9 which form luminous parts 7 are supported by these foils 1. Accordingly, even if the halogen electric lamp in an electronic copying machine or the like is provided with reciprocating motion or the like, external vibration is absorbed into the light foils 1 so that effects of the vibration on the filaments can be suppressed. Consequently the filaments can be prevented from being deformed and disconnected.

(Conventional technology and its problems) Halogen light bulbs (^) are high-intensity incandescent light bulbs that utilize a halogen cycle, but due to their characteristics, they are used as light sources for car headlights, copiers, and general lighting. It is used. Now, the halogen bulb (^) used as a light source for copying machines is usually a straight tube type as shown in Figures 1 to 4, and a molybdenum metal rod (6) is attached to a part of the filament (9) to adjust the light intensity. ) is inserted to short-circuit, forming a light-emitting part (7) and a non-light-emitting part (5) alternately, and then wrapping a support ring (8) around a metal rod (6) to form a filament (9).
was supported at the center of the glass tube (4). However, since the molybdenum metal rod (6) is a solid body, it is heavier than the filament (9), and when used in a copying machine, for example, external vibrations generated by reciprocating a halogen light bulb (^) are When the light is transmitted to the filament (9), the filament (9) gradually shifts, deforming the coil portion which is the light emitting portion (7), and there has been an accident in which the deformed portion causes a wire breakage. Currently, machine cycles tend to become faster, and it is expected that deformation of the filament (9) and disconnection accidents will increase.

(Effects of the present invention) As described above, the present invention connects the light-emitting part of the filament to a metal foil to form a filament with alternating light-emitting parts and non-light-emitting parts, and arranges the filament in a glass tube. Since the metal foil is used as a support for the filament by contacting the inner peripheral surface of the glass tube, the filament is supported within the glass tube by the lightweight metal foil that is scratched. , during the reciprocating motion of the halogen bulb,
Even if external vibrations are transmitted to the halogen bulb, the support metal foil will not shift due to external vibrations, and the advantage is that it can be used for a long period of time without deforming the filament or breaking the wire.

As mentioned above, since the metal foil is used as a support, the distance in contact with the glass tube is much longer than that of conventional support rings, which creates greater resistance when external vibrations are applied to the filament. However, it is very effective in preventing filament deformation and breakage.
