Definitions

  • the invention relates to a display case for receiving transparent advertising posters and the like, translucent, film-shaped information carriers, consisting of an in particular upright frame frame, with at least one, preferably on both broad sides of the showcase, transparent fillings, behind which the transparent information carriers or posters are arranged, wherein bulbs, in particular tubular lamps, arranged at a distance from one another are installed in the interior of the showcase, and a diffuser is held between the bulbs and the information carriers.
  • Such showcases are widely known in the prior art. For example, you will be at public Places or other suitable places that are accessible to the public.
  • the usual showcases are usually cuboid and have transparent fillings and poster carriers on both broad sides, so that in the showcase with a lighting device arranged inside both surfaces serving as advertising space are illuminated.
  • a shape deviating from the cuboid shape for example a triangular or also circular shape, in which case illuminants are then arranged at a distance behind the transparent filling.
  • the object of the invention is to create a display case of the type mentioned at the outset in which a better light distribution is achieved, which in particular should be almost completely uniform, and which light distribution can also be achieved with a smaller number of lamps per transparent filling, which absorbs less light, so that an energy saving effect is achieved.
  • the invention proposes that the lens has zones of different light transmittance, that the areas of the lens that are orthogonal to the illuminants have the lowest light transmittance and that the light transmittance increases with decreasing light intensity and increasing distance from the illuminant.
  • This arrangement ensures that a certain attenuation of the transmitted light effect is effected in the areas in which the illuminants emit particularly bright light, while in areas of decreasing light intensity a higher light transmission is achieved, so that overall an evening out of the illumination of the advertising medium or the like is achieved becomes.
  • the lens consists of clear material, especially plastic films.
  • zones of different light transmittance are formed by a color grid applied to the lens.
  • the color grid is formed from color dots which on the one hand reduce the light transmittance and on the other hand reflect the light. This effect also results in better light scattering.
  • an air and light-permeable spacer be inserted between the lens and the information carrier.
  • the spacer is formed by a plastic fabric, scrim, knitted fabric or the like, which is arranged at a distance in front of the lens and against which the information carrier can be placed on the side facing away from the lens.
  • the spacer consists of a polyester fabric, which is formed from monofilament threads with a thread thickness of about 0.3 mm.
  • a preferred embodiment is seen in the fact that in a showcase approximately 1.30 m wide, three vertically directed fluorescent tubes are arranged in a uniform distribution over the width.
  • the display case serves to hold transparent advertising posters 2 or similar translucent foils or poster-shaped information carriers. It consists of a preferably upright frame 3, which is only indicated schematically in the drawing.
  • a transparent filling 4 for example made of clear plastic film, is arranged on both broad sides of the display case 1, behind which the transparent information carriers or posters 2 are arranged.
  • spaced-apart lamps 5, in particular tubular lamps are installed.
  • a diffusing screen 6, for example made of clear acrylic glass, is additionally held between the illuminants 5 and the information carriers 2.
  • the lens 6 has zones 7 of different light transmission. The areas of the diffusing screen 6 which lie opposite the illuminants 5 orthogonally have the lowest light transmission. These zones are designated 8.
  • the light transmission increases correspondingly with decreasing light intensity and increasing distance from the illuminant 5.
  • the zones 7 of different light transmittance are formed by a color grid printed on the lens 6, for example from the finest white dots.
  • a translucent spacer 9 is inserted between the lens 6 and the information carrier 2.
  • the spacer 9 is formed by a plastic fabric or the like, which is arranged at a distance in front of the lens 6 and to which the information carrier 2 is placed on the side facing away from the lens 6.
  • the spacer 9 thus serves as a diffuser for the light beams and additionally as a support element for the information carrier 2.
  • A can be used as the starting material for producing the spacer 9
  • Polyester fabrics made of monofilament threads with a thread thickness of about 0.3 mm are used.
  • the mesh size of the fabric formed from it can be relatively large.
  • a showcase 1 approximately 1.30 m wide, three vertically directed fluorescent tubes 5 are arranged in a uniform distribution over the width, the edge distance of the outer fluorescent tubes being approximately 1/3 m.
  • This arrangement creates a power-saving lighting of the display case 1, which may even be suitable for the lighting to be supplied with solar cells.
  • the inventive design ensures uniform illumination of the information carrier 2 despite the small number of lamps 5 over the entire area.
  • the invention is not limited to the exemplary embodiments, but is often variable within the scope of the disclosure.
