ABSTRACT:
The present invention is to provide a gas discharge tube which is properly lighted to improve the reproducibility of a satisfactory light emission state. The gas discharge tube includes an envelop for accommodating a hot cathode for emitting thermoelectrons, an anode for receiving the thermoelectrons, a focusing electrode having a focusing opening for converging paths of the thermoelectrons, and a discharge shielding member supporting the focusing electrode and the anode, the discharge shielding member further supporting a cathode box for surrounding the hot cathode while being electrically insulated from the focusing electrode. Since a lighting device for the gas discharge tube sets the focusing electrode to a zero or negative potential while an electric field is generated between the hot cathode and the anode, the lighting device will be certainly turned on.
