ABSTRACT:
A discharge tube including a tubular vessel which is filled with gases, and including a first gas and second gas, the first and second gases being different in excitation level and luminous color from each other. A first electrode unit axially applies an electric field to the vessel to generate a positive column in the vessel. A second electrode unit applies an electric field to the vessel to generate a negative glow in an area, the area extending substantially along a wall surface of the vessel and confronting the positive column generated by the electric field applied by the first electrode.
