摘要： The present invention relates to a metal halide lamp with a ceramic discharge tube, which includes a ceramic discharge tube and two electrodes. The ceramic discharge tube includes a main discharge tube and two ceramic capillary tubes respectively located at two ends of the main discharge tube, the main discharge tube has a central protuberant part located in the middle thereof and two cylindrical parts respectively connected to two ends of the central protuberant part, the two cylindrical parts are respectively connected to the two ceramic capillary tubes. The shape of the ceramic discharge tube may, under the premise of maintaining high efficacy, effectively reduce the highest temperature in the center of the tube body, thereby greatly enhancing lamp reliability, and meanwhile with such structure, a fixed cold spot is also formed at a lower end of a discharge cavity formed at central protuberant part, so that a filler may always be fixedly deposited at the cold spot; in this way, the stability of the color temperature of the metal halide lamp with a ceramic discharge tube may be effectively improved.
