A gas discharge lamp ( 1 ) is described. The gas discharge lamp ( 1 ) has an inner bulb ( 2 ) with a discharge vessel ( 3 ) and two sealing sections ( 4, 5 ) arranged on the discharge vessel. From the sealing sections ( 4, 5 ) electrodes ( 6, 7 ) protrude into the discharge vessel ( 3 ) each of which are electrically connected with a conductor ( 9 ) running in the associated sealing section ( 4, 5 ) in order to supply current to the electrodes ( 6, 7 ). The gas discharge lamp ( 1 ) also has an outer bulb ( 10 ) which surrounds the discharge vessel ( 3 ) leaving a cavity ( 12 ) between the discharge vessel ( 3 ) and the outer bulb ( 10 ). Close to at least one of the two electrodes ( 6, 7 ) in the transitional area between the discharge vessel ( 3 ) and the associated sealing section ( 4, 5 ) or at a short distance from this transitional area on the outside of the inner bulb ( 2 ) is arranged potential-free a conductive structure ( 13, 13' ) which on application of a voltage to the electrodes ( 6, 7 ) influences the electrical field present in the area of the electrodes ( 6, 7 ) concerned such that a discharge arc ( 15 ) travels from the electrode ( 6 ) concerned first in the direction of a wall section of the discharge vessel ( 3 ) adjacent to the electrode and then over the inside of the wall towards the other electrode ( 7 ). A method is also described for igniting such a gas discharge lamp ( 1 ). |
