Both fire-protected known from these writings Luminaires are on the inside of their housing wall covered with heat-insulating material. To here one sufficient thermal insulation can be achieved significant amounts of insulating material required, so that the weight of these lights and thus the Manufacturing costs and installation costs for this Lights are very high.
  • a fire-proof luminaire to indicate that compared to the stand the technology has a reduced weight and the still offers high thermal insulation.
  • the luminaire should last up to fire-related failure compared to conventional, thermal non-insulated lights are extended so that important Time for rescue and extinguishing measures is gained.
  • the lid is designed such that its Inner wall that of the inner walls of the housing body formed space and with this an inner housing forms and that its outer wall that of the outer walls of the Housing body completes space and with this one Forms outer housing.
  • At least one has the Wall delimiting the air gap is an inflow opening for Cold air and a discharge opening for heated air the inflow opening and / or the outflow opening with a external ventilation system is in fluid connection, so that the air spaces are cooled by convection and thus to reduce the heat transfer from Outer housing is achieved on the inner housing.
  • the inflow opening is preferably one end Piping system connected, the other end at one lower place, for example at the level of a floor tunnels illuminated by the fire-protected lamp, empties.

  • One first bursting of the outer glass pane, which leads to the The point in time should be very sooty, also worries for the fact that the not yet sooty inner pane of glass then again the full light output lets through this too then sooty and finally burst too.
  • the Cascading of two thermally resistant glass panes hesitates the time until the lamp fails completely and creates additional time for rescue and extinguishing work.
  • the lid Preferably there is at least one other outside in the lid located translucent sacrificial disk provided by the glass pane spaced apart in the outer wall of the lid the outside of which faces away from the inner wall.
  • This victim disc keeps the first thermal attack of the Fire stood and takes the early stages of a fire usually above average soot. she then bursts at a time when the temperatures of the Fires are so high that the peak of soot development soot is exceeded or hardly any more soot in the combustion gases is included, so that the outer pane of glass then hardly sooty, which means the lighting of the fire site lasts longer is guaranteed.
  • thermally insulating Spacer also ensure that the outer housing wall for a defined distance between Outside and inside wall and thus for a defined width of the heat-insulating air space and prevent due to their thermally insulating property the formation of a Thermal bridge between the outer and inner wall.
  • thermally insulating Materials e.g. Insulating elements made of calcium silicate, provided, there may be an additional time delay heating of the inner lamp housing can be achieved, because, for example, that of the already heated outer wall radiated heat does not cover the wall of the inner housing directly reached, but from the thermally insulating Material is caught or slowed down.
  • a further improvement in the thermal insulation of the fire-protected lamp is achieved in that the Outside of the outer wall of the housing body and preferably also the lid outside of Light passage areas with foaming fire protection lacquer are provided.
  • the fire-protected according to the invention Luminaires in an arrangement of a plurality of fire-proof lights used, at least one first lamp is provided with an inflow opening, the is preferably connected to the piping system, wherein at least one last lamp with an outflow opening is provided, preferably another lamp is provided between the first and the last lamp and where the first lamp, the last lamp and the further lamp (s) are in fluid communication with each other.
  • At least one last lamp with an outflow opening is provided, preferably another lamp is provided between the first and the last lamp and where the first lamp, the last lamp and the further lamp (s) are in fluid communication with each other.
