    • In a gas discharge tube 1 of the present invention, a focusing electrode portion 14 and a discharge limiting portion 30 are electrically insulated, and the discharge limiting portion 30 comprises a discharge limiting opening 31 which opposes an arc ball shaping concave portion 16. Thus the formation of a discharge path from a cathode portion 20 to the concave portion 16 is ensured and a starting discharge can be reliably generated. Further, by means of the discharge limiting opening 31 which opposes the concave portion 16, an arc ball S can be continuously maintained in an appropriate shape even when a lamp is illuminated, and thus the arc ball S can be shaped with stability, thereby stabilizing the luminance and light quantity.
    • 在本发明的气体放电管1中,聚焦电极部14和排出限制部30电绝缘,排出限制部30包括与电弧球成形凹部16相对的排出限制开口31.因此, 确保从阴极部20到凹部16的排出路径的形成,可靠地产生起动放电。 此外,通过与凹部16相对的排出限制开口31,即使在灯被点亮的情况下,也能够将电弧球S连续地保持为适当的形状,从而可以稳定地成形圆弧球S,从而稳定 亮度和光量。

    • While high heat is generated in the anode section in the gas discharge tube in accordance with the present invention during its use, the heat is transmitted to the stem by way of the anode support plate due to a configuration in which the anode support plate abuts against the stem, and is released outside from the stem, whereby the cooling efficiency of the anode section is improved. Since the anode section employs not a floating structure including stem pins interposed therein but a configuration in which it is seated on the stem by way of the anode support plate, the anode section is stabilized on the stem, whereby the resistance to vibration improves. Also, for assembling the anode section into a sealed envelope, it will be sufficient if the anode support plate is mounted on the stem, which contributes to improving the easiness in assembling the gas discharge tube.
    • 在使用本发明的气体放电管的阳极部产生高热的同时,由于阳极支撑板与阳极支撑板抵接的结构,热量通过阳极支撑板传递到杆体 并且从杆部向外释放,从而提高了阳极部的冷却效率。 由于阳极部分不使用包括插入其中的杆销的浮动结构,而是通过阳极支撑板将其置于杆上的构造,阳极部分在杆上稳定,由此抵抗振动提高。 此外,为了将阳极部件组装成密封的壳体,如果将阳极支撑板安装在杆上则足以有助于提高组装气体放电管的容易性。

    • A gas discharge tube includes a first spacer, a second spacer, an anode support member, and an anode. The first spacer is arranged to contact the rear surface of the focusing electrode support member and the front surface of the anode, and the second spacer is arranged to contact the front surface of the anode support member and the rear surface of the anode. This arrangement clamps the anode between the first and second spacers to hold the anode securely between the rear surface of the focusing support member and the front surface of the anode support member, keeping the distance between the focusing electrode and the anode constant. This structure improves the service life and the operational stability of the gas discharge tube during continuous light emission over an extended period of time.
    • 气体放电管包括第一间隔件,第二间隔件,阳极支撑构件和阳极。 第一间隔件布置成接触聚焦电极支撑构件的后表面和阳极的前表面,并且第二间隔件布置成接触阳极支撑构件的前表面和阳极的后表面。 这种布置将阳极夹在第一和第二间隔件之间,以将阳极牢固地夹持在聚焦支撑构件的后表面和阳极支撑构件的前表面之间,从而保持聚焦电极和阳极之间的距离恒定。 这种结构在长时间连续发光期间提高了气体放电管的使用寿命和操作稳定性。
