    摘要： The present invention has an object to provide a cold-cathode discharge lamp which can suppress sputtering on a lead-in wire and reduce consumption of mercury so as to achieve a longer lifetime without increasing an amount of applied mercury. The cold-cathode discharge lamp of the present invention is characterized in that a lead-in wire connected to a cylindrical electrode in a lighting tube is made of a material same as a material that forms the cylindrical electrode. It is possible to suppress concentration negative glow discharge shifted to the lead-in wire and to allow the electrode to be covered with even negative glow discharge. Thus, it is possible to reduce mercury consumed by excessive sputtering on the outer surface of the internal lead-in wire and to achieve a longer lifetime of the cold-cathode discharge lamp.

    摘要翻译： 本发明的目的是提供一种冷阴极放电灯，其可以抑制引入线上的溅射并降低汞的消耗，从而在不增加施加的汞的量的情况下实现更长的寿命。 本发明的冷阴极放电灯的特征在于，与照明管中的圆筒形电极连接的引入线由与形成圆筒形电极的材料相同的材料制成。 可以抑制向负极辉光放电的浓度偏移到引入线，并且允许电极被均匀负的辉光放电覆盖。 因此，可以减少内部引入线的外表面上的过度溅射所消耗的汞，并且能够实现冷阴极放电灯的寿命更长。

Thus, sputtering of a small-sized electrode is suppressed thereby to suppress consumption of a rare gas sealed in a lamp so as to increase a life time, and a decrease of an emitted luminous flux is prevented.

    摘要： The present invention has an object to provide a cold-cathode fluorescent lamp which can suppress sputtering caused by electric discharge and reduce consumption of mercury so as to achieve a longer lifetime even if a lamp current is large and a lighting tube has a small diameter. The cold-cathode fluorescent lamp according to the present invention is characterized in that a distance between the inner surface of the lighting tube and the outer surface of a cylindrical electrode is set such that electric discharge develops mainly on the inner surface of the cylindrical electrode. When the lighting tube has an inside diameter D1 of 1 to 6 mm and the maximum lamp current is 5 mA or more, an outside diameter D2 of the cylinder electrode is preferably set at D1−0.4 [mm]≦D2
