Definitions

  • the invention relates to a flat signal display according to the preamble of claim 1; such a signal display is known from FR-A-2 445 485 and DE-A-2 951 471.
  • the known signal displays have elaborate constructions that can be assembled on the spot, among other things. They are either to be mounted on plaster, the devices have a depth of 50 mm or more, or to be installed under plaster. Here, a complex wall recess is necessary. These displays are generally operated at 220 V, the power consumed being 20 to 50 W and more, depending on the size of the display. The heat exposure of these displays is considerable, as far more than 90% of the installed power is converted into heat.
  • a lighting device with an edge-illuminated curved light stick is known, in which for the complete illumination over the length of the light stick with increasing distance from the light source reflecting surfaces are arranged.
  • the object of the invention is seen in an assembly-friendly signal display. It should be bright with low power and evenly illuminated.
  • the object is achieved in a signal display of the type mentioned by the characterizing teaching of claim 1.
  • All or part of the exciting light source can be arranged in the plastic filament.
  • the signal systems according to the invention have a low overall depth and low electrical power consumption. It was surprising that with the use of glass-clear plastic or fluorescent plastic and the use of so-called miniature lamps, signal displays can be operated with significantly less power and with the same brightness. They have the further advantage that they can be operated with low voltage, e.g. B. 12 V to 24 V can be operated. This allows a light design to be chosen. Furthermore, they can be used safely in so-called wet rooms. If designed accordingly, the devices can also be operated with 220 V AC or DC voltage.
  • Suitable light sources of small dimensions and power are, for example, miniature lamps (glass bulb 0 approx. 5 mm, power max. 2 W). Furthermore, glow lamps or LEDs, i.e. generally lamps with low heat generation.
  • the plastic part a so-called luminous element
  • a reflective layer on the sides where no light is to escape.
  • Views pigmented with white have proven to be particularly favorable, for example colors pigmented with rutile or heavy spar.
  • An enveloping box made of white pigmented plastic or made of white lacquered metal, wood or other material can also be used.
  • the plastic filament which can contain crystal clear or fluorescent dye, can be based on polymethyl methacrylate, polycarbonate, styrene acrylonitrile, polyvinyl chloride, epoxy and polyester resin. It can be machined from semi-finished products. Manufacture by injection molding has proven to be particularly suitable.
  • the symbols usually carried by the luminous element can be printed on this directly in any color tones as far as possible, for example by means of tampo printing or by sticking or laying on a film or plate.
  • the symbols can also be worked out from the foil or plate. Generating the symbols by screen printing is particularly favorable.
  • the symbols 12 can be made of fluorescent plastic by means of a correspondingly processed film 5.
  • the fluorescent agent incorporated into the film converts all light emerging from the luminous body into a color tone corresponding to the fluorescent agent.
  • the symbol is either printed or elaborated, e.g. B. punching. In the latter case, the symbol 12 of the color of the luminous element appears, the fall in the color of the film 5.
  • a uniformly luminous, large luminous area is produced by such a pigment print on the back that the pigmented area of the luminous element increases with increasing distance from the built-in light sources.
  • signal displays which are also called pictograms, among other things, can be used for devices or parts, symbols, characters or to mark representations of any kind more clearly with light or to achieve a signal effect.
  • the luminous element itself can also be used as a low-power lighting element, so-called dim light. It can be used as an emergency light, for example in stairwells, in bathrooms and children's rooms. In bathrooms, the light fixture can be designed so that it has the geometry of a tile and can therefore be embedded flush in the wall.
  • FIG. 4 the structure of a commercially available signal display 10 of the same display size is outlined in FIG. 4.
  • the illustration corresponds to that in FIG. 1. It can be clearly seen from this that the conventional devices require a considerably deeper installation space, in particular with regard to the recess 13 required for the light source 14.
