ABSTRACT:
A discharge lamp has an outer discharge tube and an inner discharge tube. The outer tube includes an envelope of glass enclosing an inert gas, a first electrode mounted within the envelope, a second electrode formed of a transparent film deposited on the exterior surface of the envelope, and a fluorescent material coated on the interior surface of the envelope for producing a light in a desired color when a voltage is applied across the two electrodes. The inner tube is inserted in the outer tube and includes an envelope of glass enclosing an inert gas, a third electrode mounted within the envelope, the third electrode utilizing the second electrode of the outer tube as an opposite electrode for producing luminous discharge, and a fluorescent material coated on the interior surface of the envelope for producing a light in a color different from the one produced by the fluorescent material on the outer tube.
