Abstract
PURPOSE: To prolong life by preventing the oxidation of lead-in wires in case of the formation of a mount, by shaping the unified mount by attaching bead glass for bridge between glass for sealing fastened for the pinch sealing of the lead-in wires.
CONSTITUTION: Glass for sealing 17 attached up to the pinch sealing prearranged portions and the bead glass attached portions, which extend to other portions except said prearranged portions, of lead-in wires 14, 15. A space between one portions of glas for sealing 17 is unified at a fixed void by mutually attaching bead glass 13. Portions except the glass for sealing 17 are heated as little as possible at that time. A filament 16 is supported between the upper ends of the lead-in wires 14, 15 to shape a mount 12, and the mount 12 is pinch sealed into a glass bulb, thus forming an incandescent lamp.
