Abstract (en)

[origin: DE10238096B3] The gas discharge lamp has at least 2 electrodes (1,2) for generation of a radiation emission plasma (8) in a discharge space (6) between them, one of the electrodes provided with an opening (4) leading to an adjacent external region (9) in which charge carriers are generated. The opening allows transport of the charge carriers to the discharge space, the opening tapering in the direction of the external region.
