ABSTRACT:
A fluorescent lighting structure having an inner glass envelope and an outer glass envelope surrounding the inner glass envelope, an ionizable gas contained within the volume between the inner and outer glass envelopes, an electrode structure disposed on the inside surface of the inner glass envelope, a phosphor coating disposed on the outside surface of the inner glass envelope, and an ultraviolet reflective coating on the inside surface of the outer glass envelope. Excitation of the electrode structure causes discharge of the ionizable gas that produces ultraviolet radiation, which in turn excites the phosphor coating to emit visible light.
