記載の蛍光管。[Claims for Utility Model Registration] 1. A long cathode supported by a plurality of support parts is applied with alternating voltage at a constant cycle to the support parts, and thermionic electrons emitted from the cathode are transferred to a substrate. A fluorescent tube that causes the phosphor provided on an anode to collide with the phosphor to cause the phosphor to emit light, comprising: a coil spring support provided near both ends of the cathode; A fluorescent tube characterized in that the coil spring support is provided with a coil spring whose both ends are fixed. 2. Claims for registration of a utility model characterized by providing means for applying a DC voltage instead of alternating voltage applied at a constant cycle to the cathode, and means for applying a voltage to the coil spring to heat it. The fluorescent tube according to item 1.
