Claim 5:
6. An electrodeless light emitting device comprising:
a discharge vessel hermetically enclosing a gaseous substance, the gaseous substance being ionizable by an electromagnetic excitation means, thereby inducing circulation of a discharge current in the high light transmittance vessel, the discharge vessel comprising a non-cylindrical, hollow shaped envelope, wherein the non-cylindrical, hollow shaped envelope comprises a tubular segment at least partially enclosing an internal segment, the internal segment comprising one of a tube and a rod; and
wherein:
when the discharge current circulates in the non-cylindrical, hollow shaped envelope, a hollow-shaped plasma is created therein, and
the tubular segment at least partially encloses the internal segment in a coaxial configuration.
