Halogen-filled incandescent lamp and inside current conductor therefor

摘要

A halogen-filled incandescent lamp includes a curved tube enclosure made of a translucent material and enclosing a gas filling and an incandescent body made of a tungsten wire helix of circular wire cross- section. The incandescent body is arranged within the enclosure. Two inside current conductors connect the incandescent body with an energizing device. Each inside current conductor has first and second spiral members and an elongated part forming together a series assembly. The series assembly is connected via the second spiral member with the incandescent body and via the first spiral member with the energizing device. The series assembly is at least partly made of a wire having a cross-sectional area exceeding that of the tungsten wire forming the incandescent body.
