ABSTRACT:
A metal vapor discharge lamp has a luminous tube constituted by a translucent ceramic tube member, end caps hermetically fixed to both ends of the translucent ceramic tube member, and electrode supporting tubes hermetically inserted into respective end caps. One of the electrode supporting tubes serves also as an exhaust tube for evacuation and also as a reservoir for a metal charged in the luminous tube. The outer end extremity of this electrode supporting tube is hermetically sealed through fusion by application of heat. This hermetic seal is formed by fusing the end of the electrode supporting tube by application of heat thereto, while keeping a heat-shielding/absorbing plate held in close contact with the electrode supporting tube.
