という問題点かあワた。(Problems to be Solved by the Invention) However, in the conventional metal halide lamp as described above, when the arc tube 1 is used with the center of gravity arranged vertically, high-pressure metal vapor with a large output is produced. Since the current in a discharge lamp is large, the magnetic field of the conducting wire 9 is strong, causing the arc to curve into an arched shape (this phenomenon in which the arc undulates in a serpentine manner is called a "snake"). ).This curvature of the arc causes a problem in that the inner wall of the arc tube near the arc becomes locally high temperature, which expands and causes damage to the arc tube.

As disclosed in Japanese Patent Application No. 33, a magnet that utilizes the mutual canceling effect of magnetic fields is used. However, in high-output high-pressure steam discharge lamps, the long arc tube makes the magnet structure large, and it cannot be used practically due to the difficulty of fixing it and manufacturing it. 】Ta.
