  • Halogen incandescent lamp, particularly for operation from power networks, and method of its manufacture
    Patent number: 5146134
    Abstract: To support a filament, or filament structure, in a halogen incandescent l, which may have a V or U filament, a straight filament, or be of the lumiline type, support ribs are placed within the lamp, which support ribs are formed from the lamp bulb material itself, by deforming the lamp bulb after local softening, for example by punches or by applying a vacuum, to provide interiorly extending, essentially tubular ribs. The tubular ribs may have circular or oval cross section, and can be placed to engage the filament to, for example, pinch the filament therebetween. In the pinching regions, the filament preferably is straight or only single-coiled and may be supported by a core pin.
