Definitions

  • the invention relates to a signal display with an exciting light source and display via luminous elements in a plastic frame.
  • 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 generated by these displays is considerable, as far more than 90% of the installed power is converted into heat.
  • 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 according to the invention by an exciting light source 7 of small dimensions and power in almost direct contact with a luminous element 6, in particular a plastic luminous element. All or part of the exciting light source 7 can be arranged in the luminous element 6.
  • 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 with the same brightness can be operated with significantly less power. They have the further advantage that they can be operated with touch-safe low voltage of, for example, 12 V to 24 V. 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 on which no light is to escape.
  • Suitable are e.g. Metal vapor deposition, metal foils, metal vaporized paper or plastic foils and layers of paint and varnish.
  • White-pigmented layers 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.
  • printing with white color on the side opposite the light exit window has advantageously proven itself in such a way that dots are printed in ever closer sequence away from the individual lamp (FIG. 5).
  • the plastics luminous body containing fluorescent dye of clear or can can be constructed on the basis of polymethylmethacrylate, polycarbonate, styrene acrylonitrile, P oly- vinyl 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 that are usually carried by the luminous element can be printed directly on it in any color tones as far as possible, for example by means of tampo printing or by gluing 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 consist of a suitably processed film 5 made of fluorescent plastic.
  • the fluorescent agent incorporated in the film converts all the light emerging from the luminous element into the color tone corresponding to the fluorescent agent.
  • the symbol is either printed or elaborated, e.g. Punching. In the latter case, the symbol 12 of the color of the luminous element appears, the surroundings in the color of the film 5.
  • a uniformly luminous, large luminous area can be produced on the luminous element of a signal display according to the invention by a pigment print on the back.
  • This is preferably constructed in such a way that the pigmented surface of the luminous element increases with increasing distance from the built-in light sources.
  • a signal display according to the invention has a uniformly luminous, large luminous surface due to a reflective, generally white background and a structure (roughening, rasterization) on the back of the luminous element.
  • the structured surface of the filament increases with distance from the built-in light sources.
  • signal displays which are also called pictograms, among other things, can be used for devices or parts in order to more clearly identify symbols, characters or representations of any kind by 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 flush-mounted in the wall.
  • FIG. 1 shows images of the structure of an S 'of the invention ignalan bale 1.
  • Figure 2 is a coupling frame, 3 a highly transparent cover plate 4 with a translucent film with 11 denotes a light exit surface.
  • On the writing film 5 is the desired in the screen printing process drive the desired symbol 12 here "EXIT" applied.
  • the luminous element 6 is a fluorescent plastic element in which the miniature lamps 7 (glass bulb 0 approx. 5 mm, connected load approx. 2 W ) are partially embedded.
  • the listed individual parts and the housing 8 can be held together by a cover frame 2.
  • the reflective layer is designated 9 in each case.
  • FIG. 1 the structure of a commercially available signal display 10 of the same display size is outlined in FIG. The illustration corresponds to that in FIG. 1. It can clearly be seen from this that the conventional devices are much deeper, in particular with regard to the required cutout 13 for the light source 14. In addition, there are additional components, for example another frame 15 and another clear plate 16 required.
