Problems solved by technology

[0005] The inner lead wire does not emit light, and is usually formed thin in a linear shape like the wire material of the filament, so the resistance is large, resulting in power consumption or heat loss due to heat generation.
As a result, there is a problem that the start-up time of the light-emitting part (filament) immediately after the lamp is turned on becomes slow, energy use efficiency becomes low, and thermal energy in the light-emitting part decreases.

Embodiment approach

[0083] As described above, according to the first embodiment according to the present invention, a halogen lamp is provided, and there is a light-emitting portion composed of a coil-shaped filament, which can reduce the metal foil of the sealing portion and the light-emitting portion. Thermal loss in the electrically connected internal lead, speeds up the start of the light-emitting portion, and improves the thermal energy in the light-emitting portion. Specifically, the resistance value of the internal lead can be reduced by using a configuration that refers to at least a portion of the light-emitting portion in which the light-emitting portion in the airfoil in the sealing portion is used, so that the resistance value of the internal lead is reduced, and the power loss in the internal lead is reduced. Thereby, sufficient electrical energy is supplied to the light-emitting portion. Further, the resistance value can be further reduced by causing the inner lead in the inner lead th...

Abstract

The invention provides a halogen lamp and a heating device. The halogen lamp is provided with a light-emitting part formed by a coil-shaped filament in a light-emitting tube, the heat loss of a conductive rod electrically connected with the light-emitting part can be reduced, the starting of the light-emitting part can be accelerated, and the heat energy in the light-emitting part can be improved. A conductive rod extending into the light-emitting tube is mounted on the light-emitting part in an energizable manner, and at least a part of the conductive rod has a recrystallization part in which a crystal structure is recrystallized.

Description

Technical field [0001] The present invention relates to a halogen lamp having a coil-shaped filament formed in a light-emitting tube. Background technique [0002] In the past, the image forming apparatus of the printer or the copying machine was mounted with a fixing unit that heats the ink heating to the recording medium, and a halogen lamp is mounted inside the fixing unit. [0003] Representative configurations of the halogen lamp are disclosed in Japanese Chartered 3873635 (Patent Document 1). In the halogen lamp shown in this document, a light-emitting portion and a non-light-emitting portion composed of a coil-shaped filament are formed in the light-emitting pipe, and the purpose of reducing electric power is suppressed by reducing the resistance of the non-light-emitting portion, in the non-lighting portion There is a short circuit conductive bar installed. [0004] In such a halogen lamp, as shown in Patent Document 1, it is generally a configuration in which the sealing...
