Patent ID: 7884549

Claim:
A gas-discharge lamp ( 1 ) having an inner envelope ( 2 ) comprising a discharge vessel ( 3 ) and two tubular sections ( 6 , 7 ) arranged on the discharge vessel, two electrodes ( 4 , 5 ) that project from the tubular sections ( 6 , 7 ) into the discharge vessel ( 3 ) and that, to enable them to be supplied with power, are electrically connected to respective electrical conductors ( 10 , 11 ) that extend through the associated tubular sections ( 6 , 7 ) and that are enclosed in the tubular sections ( 6 , 7 ) with a gastight seal along a sealing section ( 8 , 9 ), an outer envelope ( 18 ) that is connected at each of its ends to respective ones of the tubular sections ( 6 , 7 ) of the inner envelope ( 2 ) and that surrounds the discharge vessel ( 3 ) while leaving an outer cavity ( 20 ) between itself and the discharge vessel ( 3 ), and a conductive coating ( 22 , 23 ) that is arranged on the outside of the inner envelope ( 2 ) at least in a region or regions and that is conductively connected, inside the outer envelope ( 18 ), to one ( 11 ) of the electrical conductors.
