Definitions

  • the invention relates to a lighting arrangement for information boards comprising a plurality of light sources, a light disk through which light from the light sources is emitted.
  • a generic lighting arrangement for information boards is from U.S. 4,905,390 A famous. It is used in particular to display information on the airfield of an airport.
  • the lighting arrangement provides a substantially cuboid housing with two opposing openings and closing flaps assigned to the openings for closing the openings.
  • three horizontally extending fluorescent tubes which are arranged at a distance from one another, are provided as light sources.
  • Light discs are provided as part of the closure flaps. The light from the light sources is emitted through the lens. At least one area of the lens carries the information to be displayed.
  • a lighting arrangement according to the preamble of claim 1 is out EP2110802 famous.
  • the object of the invention is to specify a scalable lighting arrangement for information boards which is of modular construction and can be designed to be variable with regard to its size.
  • the invention is characterized by the features of claim 1, wherein a flatly extending holding module oriented essentially parallel to the lens and a plurality of light modules are provided, the light modules each having at least one light-emitting diode as a light source and an optical element for shaping and Deflecting light of the light-emitting diode in the direction of the light disc and wherein the light modules with each of the at least one light-emitting diode and the optical element can be fixed on the holding module at a distance such that for each light module a substantially rectangular sub-area of the light disc and through the entirety of the light modules
  • the light module for fixing the light module to the holding module.
  • at least two elastic fastening arms are provided on the light module at a distance from one another.
  • the holding module has for each light module at least two fastening longitudinal recesses formed at a corresponding distance, into which the light module is inserted with the fastening elements first. To bring the light module into an assembly position, the light module is linearly displaced relative to the holding module in an assembly direction predetermined by the orientation of the longitudinal recesses, the elastic holding arms being guided through the fastening longitudinal recesses and encompassing the holding module.
  • the particular advantage of the invention is that a plurality of LED-based light modules are provided for backlighting the lens. Since each light module backlights a partial area of the lens and the light modules together completely illuminate the area of the lens provided for displaying the information, a lighting arrangement of any size can be created by the number of horizontally or vertically adjacent light modules.
  • the backlighting is equally homogeneous here, since each light module homogeneously illuminates the subarea of the light pane assigned to it.
  • the optical element designed to illuminate an essentially rectangular sub-area of the lens can be implemented, for example, by a reflector, in particular a free-form surface reflector, which is assigned to the light-emitting diode.
  • the reflector is shaped, for example, in such a way that light emitted by the at least one light-emitting diode is reflected in the direction of the light pane and the required homogeneous light distribution is formed.
  • refractive optics can be implemented for homogeneous illumination of the essentially rectangular sub-area of the lens. This also advantageously results in the possibility of simply fixing the light modules on the holding module. In this respect, the assembly of the lighting arrangement is simplified, and the replacement of light modules can be carried out quickly and safely on site on the airfield and, in particular, without tools.
  • the light module can, in addition to the at least one light-emitting diode and the optical element a carrier plate having the light-emitting diode and an electrical contact element which is electrically conductively connected to the at least one light-emitting diode. Furthermore, a module housing of the light module and, as part of the module housing, a cover plate covering the light-emitting diode and having a light exit surface made of a light-permeable material are provided. The light emitted by the at least one light-emitting diode and deflected at the optical element is radiated via the light exit surface.
  • the carrier plate is supported in particular on the module housing of the light module.
  • the light exit surface is designed with optics. The light emitted by the at least one light-emitting diode in the direction of the light exit surface is deflected, in particular bundled or scattered, when it passes through the light exit surface.
  • the optical element of the light module is formed by the optical light exit surface of the cover plate. It can also be provided that the optical light exit surface is implemented as an optically effective part of the optical element. This advantageously makes it possible to dispense with the provision of a separate optical element. Instead, the optics are implemented as part of the module housing. Overall, this reduces the number of components in the light module.
  • the support plate fitted with the light-emitting diode, the module housing and a seal provided between the support plate on the one hand and the module housing on the other hand can be implemented as components of the light module.
  • the light module itself then only comprises three functional components that are easy and inexpensive to assemble.
  • An intermediate space that is formed between the module housing and the carrier plate and accommodates at least one light-emitting diode can be encapsulated by providing the seal in accordance with protection class IP64.
  • the light-emitting diode itself and the carrier plate are in this respect protected from the effects of the weather. The protection exists even if an outer housing of the lighting arrangement is damaged, for example, by stones or other foreign bodies thrown up when an aircraft takes off.
  • an electrical mating contact element that can be connected to the electrical contact elements of the light module is provided on the holding module for each light module.
  • the electrical mating contact element is provided on the holding module relative to the position of the longitudinal mounting recesses in such a way that, in the mounting position of the light module, electrical contact is established between the electrical contact element of the light module on the one hand and the electrical mating contact element provided on the holding module on the other hand.
  • the electrical contact can advantageously also be established in a simple manner without tools and directly during the assembly of the light module.
  • a positioning means in particular a positioning nose, is formed on the light module.
  • a further positioning means in particular a positioning recess, is provided on the holding module for each light module in such a way that, in the mounting position of the light module, an operative connection is established between the positioning means of the light module and the positioning means of the holding module for the form-fitting and / or force-fitting fixing of the light module on the holding module .
