发明名称 Electric lamp with bridge support member providing both compressive and axial support
摘要 An electric incandescent lamp (e.g., tungsten-halogen) including a light-transmitting envelope having an internal curvilinear wall, a gas mixture within the envelope, at least two support rods extending within the envelope in a spaced-apart manner, at least one bridge member within the envelope and supported substantially between the two support rods, and an electrically conductive filament structure located within the envelope and suspended from the bridge member. At least one support member, secured to the bridge member and projecting therefrom and including a U-shaped end portion for engaging the curvilinear internal wall of the envelope, is utilized to provide both compressive and axial support for the bridge member and suspended filament structure. The support member is preferably a wireform comprised of molybdenum.
