Definitions
- the invention is based on a flat radiator according to the preamble of claim 1.
- the invention also relates to a system comprising this flat radiator and a voltage source according to the preamble of claim 10.
- a flat radiator is known from DE-OS 195 26 211, in which strip-shaped electrodes are arranged on the outer wall of the discharge vessel.
- the radiator is operated with the aid of a sequence of active power pulses separated by pause times.
- a multiplicity of similar discharges similar to delta-like ( ⁇ ) burn in a plan view, that is to say perpendicular to the plane in which the electrodes are arranged, between adjacent electrodes.
- These individual discharges are lined up along the electrodes, each widening in the direction of the (current) anode.
- an overlay of two delta-shaped structures appears visually.
- the number of individual discharge structures can be influenced, inter alia, by the electrical power that is coupled in.
- FIG. 1 In order to be able to recognize the details better, only a section of the electrode area is shown. The aim is to ensure that the individual discharges form spatially denser towards the edges 1-3 of the flat radiator during operation than in the remaining part of the discharge vessel.
- the cathode strips 4 are specifically shaped such that they have spatially preferred starting points for the individual discharges. These preferred starting points are realized by nose-like extensions 6 facing the respectively adjacent anode 5. They cause locally limited amplifications of the electric field and consequently that the delta-shaped individual discharges 7 ignite only at these points.
- the second basic realization of an electrode structure for a type I flat radiator aims to increase the luminance of the individual discharges the closer they are to the edge. This is achieved (see the partial schematic representation of the principle in FIG. 2) in that the two anode strips 9a, 9b of each anode pair 9 are widened in the direction of the edges 10, 11 of the flat radiator oriented perpendicularly thereto. Typical values for the widening are approx. Up to a factor of two for the edge areas of the flat radiator and approx. Up to a factor of three for the corner areas.
- FIG. 3a shows a schematic illustration of a side view of the flat radiator from FIG. 3a.
- a variant differs from the flat radiator shown in FIGS. 3a, 3b only in that not only the anodes but also the cathodes are separated from the inside of the discharge vessel by a dielectric layer (discharge which is dielectric-impeded on both sides).
