ABSTRACT:
An incandescent lamp bulb assembly having three or four lead wires led out of the bottom of a pinched sealing neck of an envelope or bulb containing two filaments (double filament structure), said lead wires are disposed in line longitudinally of the pinched sealing neck. Each of three supports connected to these lead wires comprises a connecting arm section extending parallelly with a plane defined by the line of lead wires and lead-out direction of them and also in a direction intersecting the lead-out direction, and a stem section extending from the connecting arm section and having one end thereof fixed. Since the connecting arm section of each support is so formed as to be welded to a corresponding lead wire from a direction perpendicular to said plane, all the supports are welded to the lead wires from a same direction.
