Claims

[Scope of utility model registration request]

A light emitting tube made of a translucent polycrystal or single crystal, with a pair of opposing electrodes at both ends and at least a luminescent metal and a rare gas sealed inside, is mounted in an outer tube with a cap attached to one end. , a long proximal conductor is arranged along the longitudinal direction of the ascending arc tube, one end of the proximate conductor is attached to the arc tube support member via a thermally responsive metal member, and the other end of the proximal conductor is The arc tube is movably supported by at least two support holes in the support member, and the proximate conductor is in contact with the arc tube at room temperature, and during lighting, the arc tube is deformed by the thermally responsive metal member. A metal vapor discharge lamp characterized by being separated from the outer surface. .
