ABSTRACT:
A metal vapor discharge lamp including an arc tube1that includes a container10and power transmission members20aand20b. The container10, made of translucent ceramic, is divided into a main tube portion11and narrow tube portions12aand12bextending out from both ends of the main tube portion11. The power transmission members20aand20brespectively include electrode pins21aand21bmade of tungsten. Coils22aand22bmade of tungsten are respectively wound around ends of electrode pins21aand21b, which are respectively joined with electrode supporting members23aand23bmade of conductive cermet. Electrode length L1is set to (0.041P+0.5) mm to (0.041P+8.0) mm, “P” representing a lamp power in watts. Alternatively, a narrow tube portion length L2is set to (0.032P+3.5) mm to (0.032P+8.0) mm inclusive.
