Airports, skyscrapers, towers, etc., used as alarm signal lights on buildings or access gates, etc., as warning lights for electricity pylons, transmission towers, television towers or on vehicles that are at least temporarily outdoors.
  • a disadvantage of such signal lights is that they are exposed to the weather conditions and thereby the signaling or the emission of the signal light can be impaired.
  • the object of the invention is the contrast, to propose a signal light, especially exposed to the weather outside area, with at least one light emitting element for generating a signal light whose signal light is reliably perceptible even in adverse climatic conditions.
  • an indicator light according to the invention is characterized in that at least one heating device separate from the lighting element is provided for heating at least part of the signal light.

  • a wiper unit or the like could effectively strip or eliminate fogging, dew, snow or the like, so that the object according to the invention could also be solved with the aid of this measure.
  • the invention is also conceivable to heat electronic components or the like using the heater according to the invention, so that even extremely low temperatures do not lead to failure of corresponding components.
  • the reliability of the signal light is ensured according to the invention, even in particularly cold climatic conditions effectively.
  • the heating device is designed for heating the luminous element.
  • This measure is particularly in signal lights without dome or the like of particular advantage, since with appropriately trained signal lights snow, ice or the like would deposit directly on the luminous element, but this can be effectively compensated according to this variant of the invention.
  • a cap is provided for covering and / or protecting the luminous element.
  • the lighting element can be effectively protected against mechanical deterioration or the like.
  • the dome can be designed for advantageous signal propagation or for signal light steering, whereby the emission of the signal light can be further improved.
  • the heating device is designed to heat at least a portion of the dome. This ensures that, for example, on the dome depositing snow, ice, frost, dew or fog or can be effectively eliminated by means of the heating device according to the invention. As a result, the safe operation of the signal light is guaranteed.
  • the heating device is arranged on the outside of the luminous element and / or the outside of the dome. This could be an immediate elimination of ice or snow, etc. realized.
  • the heating device is arranged in the interior of the dome.
  • an effective protection of the heater for example, against mechanical impairment, abrasion or the like can be implemented.
  • the entire interior can be heated advantageously, resulting in a more even heat distribution in the interior and / or on the dome.
  • the heating device may have comparatively small or comparatively small heating surfaces, without the secure removal of ice and snow, etc. along large-area areas, e.g. the dome would be affected.
  • a particularly inconspicuous and / or the emission of the signal light little impairing heating device can be realized according to the invention.
  • the heating device may use a fuel such as e.g. Natural gas, hydrogen or the like, which is (catalytically) oxidized or burned and thus generates the advantageous heat for heating the signal light.
  • a fuel such as e.g. Natural gas, hydrogen or the like, which is (catalytically) oxidized or burned and thus generates the advantageous heat for heating the signal light.
  • the heating device is designed as an electrical heating resistor. Often signal lights already have an electrical power supply for the supply of the electric lighting element. With this measure, the design effort for supplying energy to the heater according to the invention is reducible.
  • an electrical heating resistor is particularly easy ausgestaltbar. For example, it is possible to resort to already commercially available electrical heating resistors. This leads to an economically favorable implementation of the invention.
  • the heating device is designed as a metal heating wire.
  • Corresponding heating wires that means in particular a comparatively thin and at the same time long wire or line-shaped heating element, impair in particular the propagation of the signal light particularly little.
  • the heating device has numerous metallic heating wires and / or electrical heating resistors.
  • an advantageous distribution of the heating device on the area to be heated of the signal light or the dome can be realized.
  • the heater is designed as a covering of the dome.
  • the coating is arranged on the inside, in particular on the inner surface of the dome, whereby, inter alia, a mechanical protection of Schubelages is realized.
  • the coating is applied by means of vapor deposition, spraying, brushing, printing or the like on the calotte.
  • any desired pattern can be produced with this method, which in particular advantageously influences the areal distribution of the heating device.
  • it is a covering, which is designed as a metallic heating wire or electrical heating resistor. This makes a particularly simple realization of the heating device according to the invention possible.
  • the heating device is arranged within the dome wall. This means, for example, that the heater is in the dome wall. As a result, the heater is particularly effectively protected by the dome. Neither from the inside nor from the outside, such a trained heating device is advantageously accessible directly, which means a particularly good mechanical protection of the heater. As a result, for example, particularly thin heating lines or heating wires can be realized, which do not affect the radiation of the signal light.
  • a fan for generating an air movement is provided.
  • the heat circulation can be further improved, in particular in the interior of the signal light, which can lead to an advantageous distribution of heat and / or heating of the signal light or the dome.
  • the dome can be made essentially of glass or plastic, whereby the emission of the signal light can be carried out in an advantageous manner.
  • a crystal clear dome and / or an at least partially colored dome can be provided.
  • At least one sensor for detecting a thermal and / or optical parameter is provided.
  • the temperature of the signal light and / or the environment can be detected with the aid of a thermal sensor.
  • an optical sensor for example, the light intensity in the signal light or outside of this can be detected.
  • the detected parameters can be made available, for example, to a control unit which, on the basis of the sensor parameters determined, for example, determines whether there is a risk that frost will occur or frost, ice, snow or the like could affect the radiation of the signal light and / or whether a freeze of the electronics or the like would be possible and / or whether snow, frost or the like has accumulated or deposited on the signal light.
  • a control unit is provided for controlling the operation of the heating device as a function of the parameter detected by the sensor.
  • control unit can automatically put the heating device according to the invention into operation. If, for example, the light conditions in the interior of the signal light and / or the temperature change, for example, the heating device can be put out of operation with the aid of the control unit. Alternatively or in combination with this, a manual switching on and / or off of the heating device according to the invention can also take place.
  • the luminous element is designed as a light bulb or halogen bulb, etc.
  • the luminous element is designed as a light-emitting diode or light-emitting diode array, etc.
  • Corresponding light-emitting diodes are characterized on the one hand their long life and low energy consumption. Accordingly, an economically favorable operation of the signal light according to the invention can be realized. However, since LEDs emit comparatively little heat, a special heating device according to the invention is particularly advantageous.
  • Figure 1 shows schematically a signal lamp with a heating device according to the invention.
  • the signal light according to FIG. 1 has a housing 1, which is designed in two parts and comprises a calotte 2 and a base part 3.
  • the dome 2 is made for example of colored plastic or glass, which is translucent.
  • the base part 3 of the housing 1 can be made of opaque plastic or the like.
