ABSTRACT:
A method and apparatus for manufacturing a bulb wherein a bead mount and a glass bulb are set in a recess in an upper surface of a heater arranged inside a hermetically sealed chamber, a first gas comprised of one component of a composition of a sealing gas in the glass bulb or an inert gas excluding the sealing gas is supplied to the chamber at a predetermined pressure after the chamber is evacuated, a second gas comprised of a remaining component of the sealing gas or all of the components thereof is sprayed in a space between the glass bulb and the bead mount at a pressure higher than that of the first gas to exhaust the first gas from the space within the glass bulb. The heater is energized after the substitution of the gas within the space of the bulb is performed, or while the gas substitution in the space is being performed, in order to heat and melt an edge portion of the bead mount and glass bulb to seal the glass bulb to the bead mount with the second gas sealed within the glass bulb.
