Definitions

  • Such lighting systems are used for a variety of lighting tasks, in particular for lights in general lighting and for the backlighting of liquid crystal screens (LCD) - there also known as backlight units (BLU).
  • LCD liquid crystal screens
  • BLU backlight units
  • background lighting tasks especially large-format LCD televisions are to be mentioned, which have recently gained increasing attention.
  • the invention is particularly aimed at flat-type lamps of the type of dielectric barrier discharge lamp.
  • this type of lamp either the electrodes of one polarity or all the electrodes, ie the electrodes of both polarities, are separated from the discharge by means of a dielectric layer (a one-sided or two-sided dielectrically impeded discharge).
  • a dielectric layer a one-sided or two-sided dielectrically impeded discharge.
  • Such electrodes are also referred to below as "dielectric electrodes.”
  • the dielectric layer does not have to be a layer specially applied to an electrode for this purpose, but may also be formed, for example, by a discharge vessel wall, if indeed typically strip or line-like electrodes are arranged on the outside of a discharge vessel wall or within the wall.
  • the document EP 1 600 808 A1 discloses a lighting system with a flat lamp. There, the flat lamp is inserted into a housing with rear wall and circumferential side wall. A mounted on the side wall and also encircling frame fixes the flat lamp inside the housing.
  • the lighting system according to the invention has a flat lamp whose edge region is provided with a frame which has a substantially U-shaped profile.
  • the frame itself consists of one or more similar parts with U-profile. Thanks to the U-profile, the individual frame parts can simply be placed on the edge of the flat lamp. In this case, the two legs of the U-profile surround the edge region of the flat lamp.
  • the U-shaped profile of the frame or of the individual frame parts is preferably formed integrally as such.
  • the frame is preferably made of plastic, eg silicone, and is preferably designed as an injection mold. This combines the advantage of ease of manufacture with the ease of use, since each frame part is in one piece and therefore can be easily plugged onto the corresponding edge region of the flat lamp.
  • the frame allows compliance with the relevant electrical protection regulations, for luminaires such as UL 1598 and EN 60598-1, for compliance with the required creepage and clearance distances in the edge area.
  • luminaires such as UL 1598 and EN 60598-1
  • the frame allows compliance with the relevant electrical protection regulations, for luminaires such as UL 1598 and EN 60598-1, for compliance with the required creepage and clearance distances in the edge area.
  • the latter is of particular importance when the flat lamp is provided with electrode tracks arranged on the outside of its base plate, as explained in the applicant's US Pat. No. 6,762,549.
  • dielectric strengths for voltages of several kilovolts, in particular at least 5 kV are required.
  • silicone has proven to be suitable.
  • PE Polyethylene
  • PP polypropylene
  • PMMA Polymethylmethacrylate
  • PS polystyrene
