Summary:Electrodeless low-pressure discharge lamp having a lamp vessel (1) which is sealed in a gas-tight manner and which is filled with a metal vapour and a rare gas, which lamp has a core (4) of a magnetic material, whilst during operation of the lamp an electric field is generated in the lamp vessel (1) by means of a winding (5) surrounding the core and a high-frequency supply unit (6) connected thereto, a transparent electrically conducting layer (13) being present on the inside of the lamp vessel, which layer is connected to an electric conductor (11) located outside the lamp vessel by means of a lead-through member (10) incorporated in the wall of the lamp vessel. The lead-through member (10) is electrically connected to a contact strip (12) of conducting material extending on at least the greater part of the circumference on the inside of the lamp vessel and being electrically connected substantially throughout its length to the transparent conducting layer (13).
