Definitions

  • the present invention deals with an escape sign luminaire with a self-illuminating display which, electronically controlled, can alternately display at least two different direction and / or path information.
  • the present invention deals with an escape sign luminaire according to the preamble of claim 1.
  • the present invention also deals with a communication method for switching a display of an escape sign luminaire, which is intended in particular for signposting various escape routes.
  • the present invention deals with a communication method according to the preamble of claim 17.
  • the present invention is concerned with a method for guiding escape routes through a corresponding system with at least two escape sign lights and a guidance system, the guidance system preferably being able to be brought into a data exchange connection with each of the exit sign lights via a bidirectional communication device.
  • the present invention is concerned with a method for operating a corresponding escape route control system, in which a corresponding escape sign luminaire is also to be operated, according to the preamble of claim 18.
  • a luminaire that is intended for use as an escape sign luminaire can indicate to people via which escape route a certain location, e.g. B. a building should ideally be left in an emergency situation. This means that the exit sign luminaires must be clearly visible, even in poor lighting conditions. Escape sign luminaires are often installed in corridors or passageways, for example to help people flee from a source of danger, such as a fire, to decide which route is the safest route is to be taken, to decrease or to make it easier. The aim is that fleeing people do not lose valuable time in their escape due to a lack of orientation or due to their ignorance of the exact local conditions.
  • each subpixel has a thin-film transistor. This should be able to be controlled in a manner analogous to TFT technology, after which a pixel that is excited to glow is retained until the next corresponding pulse and emits light. This should not only enable a better contrast value compared to TFT-LC (D) displays; the contrast should also be given regardless of a changing viewing angle.
  • OLED displays do not require backlighting. As a result, such luminaires have a lower electrical power consumption and an improved energy balance.
  • very fast switching times in the microsecond range should be possible with OLED technology, so that a viewer of an OLED luminaire should no longer really perceive the transition from a first display to a second display.

  • TFT-LCDs are also written on.
  • the light should be guided with these LCDs.
  • a corresponding flat panel monitor is arranged in a housing together with a backlighting unit.

  • This display designed in this way is a prerequisite for the EP 2 902 995 A1 luminaire technology described can be implemented at all.

  • the display of the emergency light should be an illuminated, backlit or backlit display, for which an emergency battery should supply the energy for the lighting in the event of failure of the voltage supply network supplying the display. This should be waived if the emergency sign light has a display that is an electronic paper (e-paper, e-ink). If one sensor is allowed to control its own luminaire at will, escape routes that do not directly lead refugees into security areas via the shortest possible route should almost inevitably be preprogrammed.
  • the DE 20 2016 102 969 U1 (Owner: Zumtobel Lighting GmbH; Date of registration: September 6th, 2017) suggests using PDLC foils for luminaires. If the supply voltage breaks down, the crystals in an LC light lose their alignment and display becomes opaque. An escape sign can be made visible through a PDLC film cut to a pictogram. As long as voltage is applied to the luminaire, the PDLC film can become (almost) invisible due to the transparency of the display. Such a luminaire looks promising due to its emergency operation properties, but should not offer sufficient, standard-compliant brightness and contrast and thus visibility.

  • a first exit sign luminaire 30 I is provided with a first display image (see, for example, display image 46 in FIG Figure 1 ) and a second exit sign luminaire 32 a second display image (see, for example, display image 48 in FIG Figure 1 ) assigned by the received escape route indicator 99, it being possible for the two display images to differ.
  • further display images of further escape sign luminaires e.g. the third display image 50 of the third escape sign luminaire 34 in FIG Figure 1
  • the escape route indicator 99 After selecting 108 or 108 I according to Figure 5 there is a switching 110, 110 I of the respective escape sign luminaire or of its respective display to the display mode predetermined by the escape route indicator 99.
  • a switching process takes place in particular in a display driver stage. In this way, the in Figure 1 The escape route shown causes.
  • the guidance system 22 can generate a second escape route indicator 99 I and send it to the exit sign luminaires 30, 32, 34 send.
  • the escape sign lights 30, 32, 34 make their own selection of their display mode on the basis of the second escape route indicator 99 I from the display modes held in their memory.
  • the first escape route 24 can be blocked by a route information such as the route information 58 on the first escape route luminaire 30 and the second escape route 26 can be indicated by a directional information such as the directional information 56 on the second escape route luminaire 32.
  • the emergency lighting system such as the emergency lighting system 20 in FIG Figure 1 to react to a changed danger situation and to show the safest or fastest possible escape route to the building exit.
