ABSTRACT:
A luminous tube is provided with three color producing inner tubes and is mounted within a clear outer tube. The luminous gas filling the outer tube also fills the open-ended inner tubes. Each of the color-producing tubes has an electrode to enable the current density to be independently controlled, and thus control of the light-intensity emitted from each of the color-producing tubes. A luminous tube may also be constructed with at least one tube mounted inside an outer tube within a common luminous gas, where the inner tube houses an electrode and has a restricted diameter opening to produce a high-intensity luminous discharge.
