    • The present invention provides a metal halide lamp in which the change of the color temperature is suppressed regardless of the orientation of the light emitting bulb in use. The metal halide lamp includes a light emitting bulb of translucent ceramics that includes a light emitting portion and tubular portions that are connected to the light emitting portion. The light emitting portion includes a liquid holding portion on the inner surface of the light emitting portion so as to hold a liquefied substance that moves on the inner surface toward one of the tubular portions. The internal diameter d of the light emitting bulb at the liquid holding portion satisfies 0.4D
    • 本发明提供一种金属卤化物灯,其中与使用中的发光灯泡的取向无关地抑制色温的变化。 金属卤化物灯包括半透明陶瓷的发光灯泡,其包括发光部分和连接到发光部分的管状部分。 发光部分包括在发光部分的内表面上的液体保持部分,以便保持在内表面上朝着一个管状部分移动的液化物质。 液体保持部分处的发光管的内径d满足0.4D
