Abstract
An electrodeless low-pressure gas discharge lamp includes a glass lamp vessel (1) which is provided with a sealing member (6) connected to the wall of the lamp vessel by means of a suitable sealing material, and which has on its inner wall a conductive layer (7), at least part of which is transparent, that extends beyond the connection to the sealing member (6), the member being slightly recessed into the lamp vessel. The inner conductive layer can thus be connected in a simple manner to an electrical conductor, which during operation of the lamp is connected, for example, to one of the supply wires of the mains.
