An electrodeless discharge lamp comprises a sealed discharge vessel (1) containing a fill capable of sustaining a discharge when suitably energised, and circuitry (6,7) for energising a solenoid (5) to produce an RF electromagnetic field in the vessel to energise the fill. A light transmissive, inherently conductive, polymer layer (20) is provided on the exterior of the discharge vessel for confining the RF field within the lamp. An outer, insulating layer (21) may also be provided over the conductive layer (20). <IMAGE> |
