1. An electrodeless lamp for use in special applications such as hazardous or wet environments, comprising:

  • a light-transmissive envelope enclosing a gaseous medium adapted to sustain an electric discharge and luminous phosphors disposed on interior surfaces of said envelope and adapted to emit visible light when excited by ultraviolet radiation emitted from said gaseous medium;

    a source of RF energy adapted to receive electrical power for generating an RF electrical signal;

    an energy coupler electrically coupled to the output of said RF source and for being excited by said RF signal, said coupler being shaped to conform to the shape of a portion of said envelope and to cooperate therewith such that said coupler may be assembled to said envelope in energy-transfer relation; and

    potting material encasing said RF source and said coupler and conforming to the shape of said coupler as it is accommodated by said envelope;

    said lamp being characterized in that said envelope is removably assembled to said coupler in said energy-transfer relationship and may readily be removed and replaced.
