Claims

[Scope of utility model registration request]

In a metal vapor discharge lamp in which a pair of opposing electrodes are provided at both ends of a translucent ceramic tube, and an arc tube is sealed inside the outer bulb, the arc tube is made of a starting rare gas, mercury, and a luminescent metal. A proximate conductor for starting is provided on the surface, and this proximate conductor is electrically connected to one electrode via a thermally responsive member, and the thermally responsive member moves the proximate conductor toward the electrode of the same potential when the arc tube is lit. A metal vapor discharge lamp characterized by being thermally deformed so as to cause
