    • An automotive discharge bulb having a light emitting tube includes a ceramic tube with paired electrodes oppositely placed, and contains a light emitting material and starting rare gas. A transversal section of the ceramic tube is longitudinally elongated. Because the capacity of an enclosed space of the ceramic tube is small, after discharging begins, the enclosed space temperature increases. Consequently, the ceramic tube has a good luminous flux rising characteristic. Because of the small surface area of the ceramic tube, the load imposed on the wall surface increases. Consequently, the ceramic tube has good luminous efficiency. In the ceramic tube having a longitudinally elongated transversal section, an arc generated into an upwardly convex shape and the tube wall do not make contact. Thermal shock resistance required of the ceramic tube is alleviated, durability is enhanced, and the ceramic tube is made of a ceramic material hitherto unusable.
    • 具有发光管的汽车放电灯包括具有相对放置的成对电极的陶瓷管,并且包含发光材料和起始稀有气体。 陶瓷管的横截面纵向伸长。 由于陶瓷管封闭空间容量小,放电开始后封闭空间温度升高。 因此,陶瓷管具有良好的光通量上升特性。 由于陶瓷管的表面积小,施加在壁面上的载荷增加。 因此,陶瓷管具有良好的发光效率。 在具有纵向细长横截面的陶瓷管中,产生向上凸起的电弧和管壁不接触。 减轻陶瓷管所需的耐热冲击性,提高耐久性,并且陶瓷管由迄今为止不可用的陶瓷材料制成。

    • A discharge bulb is equipped with a discharge light emitting chamber tube in which discharge electrodes are provided face to face and a luminescent material is filled at the center of the ceramic tube in longitudinal direction. A metallic pipe is jointed into the pore of a tube end communicating with the discharge light emitting chamber. The rear end of an electrode rod inserted into the pipe with its tip protruding into the discharge light emitting chamber to constitute an electrode is jointed to the protruding tip of the pipe. A constricted part is arranged in the part between the tube center corresponding to the discharge light emitting chamber of the ceramic tube and the tube end. The thickness of the tube wall of the tube end is augmented to enhance the thermal shock resistance of the tube end. The thickness of the tube wall at the constricted part is reduced to suppress heat transmission from the discharge light emitting part to the tube end and to improve the light emission efficiency of the arc tube main unit.
    • 放电灯泡配备有放电发光室管,其中放电电极面对面地设置,发光材料在陶瓷管的中心沿纵向填充。 金属管被连接到与放电发光室连通的管端的孔中。 插入管中的电极杆的后端与其顶端突出到放电发光室中以构成电极的接头连接到管的突出尖端。 在与陶瓷管的放电发光室对应的管中心与管端部之间的部分配置收缩部。 增加管端的管壁的厚度,以提高管端的耐热冲击性。 收缩部分的管壁的厚度减小以抑制从放电发光部到管端的热传递,并且提高电弧管主单元的发光效率。

    • In a discharge bulb having an arc tube formed with pinch seal portions on both ends of a sealed glass bulb that is a light-emitting discharge section, infrared transmitting films for blocking visible light and transmitting infrared light are applied to at least the pinch seal portions of the arc tube to prevent visible light from exiting the pinch seal portions and to suppress generation of glare. Infrared light from the pinch seal portions can pass through the infrared transmitting films, which prevents accumulation of heat in the arc tube (pinch seal portions and sealed glass bulb), thereby preventing the temperature of the arc tube from increasing excessively.
