摘要:
A gas discharge lamp having a discharge vessel (202) which is at least partially transparent and filled with a gas filling, a number of essentially strip-shaped anodes (205, 206) and cathodes (203, 204) which extend on the walls of the discharge vessel and essentially parallel to each other, and a dielectric layer (215) between at least the anodes and the gas filling for a dielectrically impeded discharge in the discharge vessel between neighboring anodes and cathodes, characterized in that at least one anode pair (205) is arranged between two cathodes (203, 204) respectively adjacent to one anode pair.
摘要:
A flat radiator (4), suitable for a dielectrically impeded discharge and with a discharge vessel (5) made from an electrically non-conducting material has strip-like electrodes (6, 7) arranged on the wall of the discharge vessel (5), cathodes (6) and anodes (7a) being arranged alternately next to one another, and at least the anodes being separated from the interior of the discharge vessel (5) by a dielectric material (10). In each case one additional anode (7b) is arranged between neighbouring cathodes (6), that is to say in each case one anode pair (7a, 7b) is arranged between the neighbouring cathodes (6). The result is a uniform discharge structure accompanied by optimum utilization of the discharge vessel. FIG. 3b
摘要:
A radiation source, in particular a discharge lamp suitable for operating a dielectrically hindered pulsed discharge by means of a ballast, has at st one electrode separated by dielectric material from the inside of the discharge vessel. By appropriately designing at least one of the electrodes and/or the dielectric material, local field reinforcement areas are created, so that during the pulsed mode of operation one or more dielectrically hindered individual discharges are generated exclusively in these areas, maximum one individual discharge being generated in each area. These areas are obtained in particular by shortening the spacing in locally limited areas, for example by providing on one of the electrodes hemispherical projections which extend towards the counter-electrode. This measure achieves a timestable discharge structure with a high useful radiation effectiveness uniformly distributed throughout the discharge vessel.
