| abstract | (57) [Abstract] [Purpose] To provide a metal halide lamp which has a long life without causing cracks in the sealed portion of the arc tube. [Structure] A sealing portion 11 is formed at an end portion of an arc tube 10 made of quartz glass, and an electrode shaft 13 of an electrode is provided at this sealing portion. In a metal halide lamp in which mercury, at least one rare earth metal halide, and a rare gas are sealed in the arc tube, the coldest part of the arc tube 10 is connected to the sealing part 11. It is characterized in that it is formed on the wall surface of the discharge space away from the periphery of the electrode shaft 13. Since the coldest part is formed at a position avoiding the periphery of the electrode axis of the sealing part, the rare earth metal halide does not aggregate between the electrode shaft and the sealing part, and the rare earth metal and quartz The reaction of can be prevented, and the discoloration and deterioration of quartz can be prevented. |
