Definitions

  • the present invention relates to a signaling device with a signal plate for the attachment of incandescent lamp modules, wherein the signal plate has openings as well as fastening and / or positioning elements for the arrangement of the incandescent lamp modules.
  • LED bulbs Due to the significantly longer life of LED bulbs is therefore increasingly gone in equipment / retrofit of new or existing signal systems to use LED bulbs. These LED bulbs have a greater number of individual LEDs arranged in an array, which are collectively lit to indicate a signal concept. The failure of a single LED or a small number of individual LEDs can hardly fall due to the large number of points of light weight, which is why in addition to the incandescent lamps increased life of the LED and the system error rate is significantly lower.
  • the problem with retrofitting existing signals is that the new LED bulbs are not compatible with the incandescent bulbs and therefore usually incur high costs for the creation of new signals and at least partially scrap the existing signal structure.
  • the present invention is therefore an object of the invention to provide a signaling device with which the replacement of incandescent lamps by LED bulbs can be done in a simple and cost-saving manner.
  • a signaling device of the type mentioned in which a to the openings and the fastening and / or positioning elements adapted support member is provided, on which an LED light source is arranged.
  • the support element which may be configured, for example, as a support plate or as a carrier housing, so to speak serve as an adapter for the installation of the LED bulbs, which can be used in the originally provided for mounting and mounting of incandescent modules elements. This only has to be done during the replacement process the incandescent module can be removed as such, and the carrier element equipped with the LED illuminant can be used.
  • the carrier element can comprise a glass and / or plastic body adapted to the LED illuminant, which is arranged in the light path.
  • This glass and / or plastic body can according to the requirements have the appropriate properties, so for example serve as a scattering or converging lens.
  • an electrical terminal group of the LED light source can be made compatible with a terminal group of a light bulb module.
  • this electrical connection group may be equipped with corresponding electrical components in order to simulate the electrical properties of the incandescent lamp module.
  • means may be provided which adjust the power consumption in the LED lighting circuit to the power consumption of a light bulb module.
  • FIG. 1 shows a perspective rear view of a signal 2 which has a signal panel 4 facing a viewer, not shown here, and a rear signal panel 6.
  • the signal 2 was originally equipped with incandescent lamp modules not shown here.
  • the signal plate 6 has a plurality of openings 8, 8a and fastening elements 10 and positioning elements 12.
  • a support plate 14 is used in the present embodiment, on which an LED lighting means 16 is arranged.
  • a luminaire housing 18, a rearward heat sink 20 and an encapsulated electrical connection group 22 can be recognized by the LED illuminant 16. Thanks to the carrier plate 14 adapted to the apertures 8, 8a and the fastening elements 10 and positioning elements 12, the LED illuminant 16 can be integrated into the signal 2, without having to make any further modifications to the signal 2.
  • control unit and / or line-side control and / or monitoring it is possible with a correspondingly adapted electrical connection group 22 to maintain exactly the control and / or monitoring regime previously used for the incandescent lamp module.
  • an increased power consumption of the LED lighting means 16 is artificially caused by a parallel connection of an electrical resistance in the electrical connection group 22, which largely corresponds to the power consumption of a conventional incandescent lamp module when the LED illuminant.
  • Figure 2 shows a perspective view of the front of the signal 2 with its signal panel 4.
  • the LED bulb 16 is inserted, of which in this illustration, only a protective glass plate the LEDs 24 can be seen.
  • An enveloping body 26 narrowing the lateral emission of the signal light has already been part of the signal 2 when it was still equipped with incandescent lamp modules.
  • the glass plate 24 can be adapted to the desired radiation characteristic of the signal point, for example in the form of a scattering or condenser lens.
