Definitions

  • the invention relates to a method for operating a lighting system with an incoherently emitting radiation source, in particular Discharge lamp, by means of dielectric barrier discharge according to the Preamble of claim 1. Furthermore, the invention relates to one for this Operating method suitable lighting system according to the preamble of claim 12.
  • UV (U ltra v Iolet) - and IR (I nfra r ot) emitters as well as discharge lamps which emit visible light in particular, to understand.
  • Such radiation sources are suitable, depending on the spectrum of the emitted radiation, for general and auxiliary lighting, such as home and office illumination or backlighting of displays, such as LCDs (L iquid C rystal D isplays), for the transport and signal lighting, for UV radiation, for example disinfection or photolytics, and for IR radiation, for example for drying paints.
  • general and auxiliary lighting such as home and office illumination or backlighting of displays, such as LCDs (L iquid C rystal D isplays)
  • UV radiation for example disinfection or photolytics
  • IR radiation for example for drying paints.
  • WO 94/23442 describes a method for operating an incoherently emitting Radiation source, in particular discharge lamp, by means of dielectric disabled discharge disclosed.
  • the operating procedure sees one Sequence of voltage pulses before, the individual voltage pulses through Dead times are separated.
  • the advantage of this pulsed mode of operation is a high efficiency of radiation generation.
  • EP 0 363 832 describes a UV high-power lamp with pairs of electrodes connected to both poles of a high voltage source.
  • the electrodes are from each other and from the discharge space of the Radiator separated by dielectric material. Such electrodes are hereinafter referred to as "dielectric electrodes".
  • the electrodes are arranged side by side, whereby area-like discharge configurations with relatively flat discharge vessels let it be realized.
  • An AC voltage is applied to the dielectric electrodes in the order of magnitude of several 100 V to 20000 V. Frequencies in the range of technical alternating current up to a few kHz placed such that there is essentially only a sliding electrical discharge in the area of the dielectric surface.
  • the main disadvantage is that sliding discharges in particular place a thermal load on the surface, which is why cooling channels for dissipating the heat from the dielectric are also proposed. Due to the unavoidable, substantial heat generation of this discharge type, the efficiency for generating radiation, in particular in the UV and VUV (V acuum U ltra v Iolet) range is limited. In addition, sliding discharge causes chemical processes on the surface, thereby shortening the life of the lamp.
  • the object of the invention is to eliminate these disadvantages and a method to operate a lighting system, which both through a flat discharge vessel as well as through efficient production characterized by radiation.
  • Another object of the invention is to provide a lighting system which is suitable for the operating method. This object is achieved according to the invention by the characterizing features of claim 12 solved.
  • the basic idea of the invention is in the interior of the discharge vessel with dielectric electrodes arranged next to one another generate spatial discharge in the areas between electrodes opposite polarity a distance from the surface of the inner wall of the discharge vessel. While in the prior art one Variety of sliding discharges along the surface of the dielectric Serve generation of UV radiation, the invention proposes the use one that separates from the dielectric surface, spatially within extended discharge before the discharge vessel.
  • the advantages achieved thereby are firstly a higher efficiency of generation of UV or VUV (V acuum U ltra v iolet) radiation and hence a lower heat generation.
  • no cooling liquid is required for heat dissipation.
  • the discharge type according to the invention results in a significantly lower thermal and chemical wall load than is the case with surface sliding discharges. An extension of the life of the discharge vessel is consequently achieved.
  • a more uniform, area-like, spatially diffuse luminance distribution can be realized between the electrodes.
  • the latter offers considerable advantages over optically imaging lighting or radiation tasks, such as, for example, in photolithographic applications, in comparison to the channel-shaped sliding discharges.
  • diffuse luminance distributions directly improve process efficiency. In this regard, lighting patterns such as the conventional channel-shaped lighting structures are undesirable.
  • the method according to the invention now provides for those arranged side by side dielectric electrodes with a series of voltage pulses supplying voltage source to connect.
  • the individual voltage pulses are separated from each other by break times.
  • this procedure does not only involve radiation is generated with high efficiency, but that completely beyond that Unexpectedly, a spatial discharge is generated inside the discharge vessel that is in the areas between electrodes of different polarity a distance from the surface of the inner wall of the discharge vessel having.
  • pulse width becomes and pause time selected so that the spatial, discharge occurs partially from the dielectric surface.
  • Typical pulse widths and pause times are between 0.1 ⁇ s and 5 ⁇ s or in the range between 5 ⁇ s and 100 ⁇ s, corresponding to one Pulse repetition frequency in the range between 200 kHz and 10 kHz.
  • the optimal values for the pulse width and the pause time are in individual cases depends on the specific discharge configuration, i.e. of type and Pressure of the gas filling and the electrode configuration.
  • the electrode configuration results from the type and thickness of the dielectric, the area and shape of the electrodes and the electrode spacing.
  • the voltage signal to be applied is such a discharge configuration choose that a discharge separates from the dielectric surface that sets a maximum radiation yield at the desired electrical Power density.
  • those disclosed in WO 94/23442 are also Sequences of voltage pulses are suitable.
  • the amount of voltage pulses is typically between approx. 100 V and 10 kV.

  • the electrodes are preferred arranged parallel and equidistant to each other. This is important to everyone Discharges between the neighboring electrodes have the same conditions to ensure. This makes a large-scale and homogeneous Illumination ensured. It will also be more appropriate in this way Pulse sequence achieves optimal radiation efficiency.
  • the lateral dimensions - i.e. the diameter of the wires or widths of the strips - from anode or cathode can be different.
  • the operating method according to the invention is suitable for a large number of possible ones Discharge vessel geometries, especially for all those in the EP 0 363 832 A1. It does not matter whether the discharge vessel contains a gas filling and is sealed gastight, e.g. with discharge lamps, or whether the discharge vessel is open on both sides and is flowed through by a gas or gas mixture, e.g. in photolytic Reactors.
  • the only decisive factor for the mode of operation is that the dielectric Electrodes are arranged side by side. Side by side means here that neighboring electrodes of different polarity as it were lie on one side of the discharge zone.
  • the electrodes can be arranged in a common plane, e.g. on an outside of a wall of the discharge vessel -vtl. additionally covered with a dielectric protective layer - or directly into the Wall embedded.
