Definitions

  • the present invention relates to a safety sign luminaire used to display emergency-relevant information in the form of an illuminated pictogram.
  • the present invention relates to a luminaire used to indicate the direction of an escape route.
  • safety or escape sign luminaires are used. These luminaires indicate the direction of the escape route using a suitably designed pictogram, which is appropriately illuminated by the luminaire's light source. Because the pictogram appears brighter than its surroundings, it is immediately recognizable, and the design of the pictogram makes the direction of the escape route immediately understandable.
  • the present invention particularly concerns the question of how the pictogram is placed on the light guide in such a safety sign luminaire. For manufacturing reasons For these reasons, as well as with regard to the efficiency of light extraction, direct printing on the light guide is generally impractical. Instead, the pictogram is usually printed on a separate component in the form of a film or a thin plastic plate, which is then ideally detachably attached to the light guide plate. Various approaches are known in the art for this, for example, the corresponding film is adhered to the light guide plate using adhesive strips. The use of small expanding rivets at the corners and corresponding clips that grip the corners of the resulting arrangement is also known.
  • the present invention is therefore based on the objective of providing a novel solution that avoids the aforementioned disadvantages.
  • foil- or plate-like pictogram elements should be held neatly, attractively, and unobtrusively to a corresponding light guide.
  • subsequent replacement of the pictogram should be as simple as possible, i.e., the pictogram element should be as easy to install and remove as possible.
  • the desired interchangeability of the pictogram element is achieved according to the invention in that it is provided as a separate component compared to the light guide and additional mounting measures are provided with the aid of which the pictogram element is detachably held on the light guide.
  • the holder of the pictogram element is provided with the aid of a frame-like component which, for holding the pictogram element, comprises an edge region of the light guide plate with the pictogram element placed thereon.
  • the present invention specifically addresses the problem of arranging the pictogram element(s) 90 in a suitable manner on the light guide plate 20.
  • a frame-like holding element which is also referred to below as a frame element and is designated by reference numeral 40 in the figures, is responsible for this.
