Abstract
An electrodeless discharge lamp comprises a sealed discharge vessel containing a fill capable of sustaining a discharge when suitably energized, and circuitry for energizing a solenoid to produce an RF electromagnetic field in the vessel to energize the fill. A light transmissive, inherently conductive, polymer layer is provided on the exterior of the discharge vessel for confining the RF field within the lamp. An outer, insulating layer may also be provided over the conductive layer.
