Definitions

  • the application relates to a light, in particular safety or escape sign light.
  • a luminaire has at least one backlit visible surface which has at least one pictogram and a variable display region arranged in the pictogram or associated with the pictogram.
  • Corresponding lights are used, for example, to display an escape route and in the icon is a running person and an arrow to indicate the corresponding direction of escape included.
  • the escape direction points to a safe exit from a corresponding building. In such lights, there is a possibility that the direction of escape changes, for example, if there are smoke or fire in certain areas of the building, which require a change of the originally indicated escape route.
  • each directional display corresponds to a corresponding display area in which, for example, an arrow symbol is arranged and activated by operating the corresponding light emitting different arrow symbols with different display directions effectively become.
  • a corresponding switching of the escape direction due to a fire alarm system or a smoke detector signal received and, for example, a central control device for all existing in a building lights, as well as security or escape sign lights.
  • the invention is therefore based on the object to improve a luminaire of the type mentioned in that with little effort corresponding display areas of the visible surface are variable and at the same time the lamp meets all requirements of the above-mentioned DIN standard or standards mentioned above.
  • the luminaire is characterized in particular in that the variable display area is designed as an electrically or electronically switchable, optical shutter area, which allows light to pass through or essentially blocks depending on the switching state.
  • Such an optical shutter area is sometimes called a shutter area.
  • the passage or blocking of the corresponding light can also relate only to specific spectral regions of, in particular, visible light. That is, for example, that only a spectral range of visible light in the green area is transmitted through the shutter area, so that, for example, with white arrow symbols on a green background, the white arrow symbols in the display area are displayed green by the shutter area. This means that the white arrow symbols are no longer visible against the green background.
  • the corresponding display area is completely blocked, d. that is, no light in the visible range is transmitted through the optical shutter area in the corresponding blocking switching state.
  • each of the arrowhead is visible by driving the optical shutter area corresponding to the direction of the escape route.
  • the other arrowhead is invisible.
  • two corresponding optical shutter areas are arranged or assigned to the icon, for example, to turn left or right of the current person corresponding arrow directions to the left or right effective or ineffective.
  • the optical shutter area is assigned to different direction indicators of the icon, ie, different arrow symbols or direction indicators.
  • the corresponding direction indicators may be part of the pictogram or corresponding to it Be assigned to positions.
  • the optical shutter area relative to a light source of the corresponding direction indicator may be upstream or downstream.
  • the closure region can be arranged between the light source and the direction indicator or between the direction indicator and a viewer on an outer side of the visible surface of the luminaire.
  • the optical shutter area in Vietnamese glassschaltrus can have a transparency of greater than 70 percent, preferably greater than 80 percent and particularly preferably greater than 90 percent. That is, in the pass-through state, the optical shutter area allows more than 70 percent of the incident light to pass, and this may also be greater than 80 or more than 90 percent.
  • the corresponding permeability of the closure region may be limited to certain spectral regions of visible light and may also include IR and / or UV spectral regions.
  • the corresponding closure region only allows a given light color in the blocking switching state, such as, for example, green, yellow, red or blue light, in the case of substantially white irradiated light.
  • a given light color in the blocking switching state such as, for example, green, yellow, red or blue light
  • the blockage affects all white light, i. h., That the closure area is opaque.
  • LEDs light emitting diodes
  • corresponding LEDs are arranged in particular along a light entry edge of a Lichtverteilplatte, which is also part of the corresponding lamp.
  • the light of the LEDs is radiated into the light distribution plate from the light entry edge and emitted by the latter via at least one side surface in the direction of the pictogram relative to the background illumination thereof.
  • pictograms and corresponding display regions or optical shutter regions are arranged on both sides of such a light distribution plate.
  • the closure region may be formed as an LCD shutter region.
  • the corresponding technique of such a shutter area is known, for example, from corresponding LCD shutter glasses, such glasses having glasses consisting of two liquid crystal surfaces. One of these surfaces is intended for the left eye, the other for the right eye.
  • the corresponding liquid crystal surfaces can be electronically switched between permeable and impermeable. This serves to darken either the left or right eye. In this way, the viewing of 3D images or films is possible.
  • a corresponding LCD shutter area may be considered a large LCD pixel that is switched to either transparent or opaque.
  • the display area is changed, see, for example, the activation of different arrow symbols.
  • the switching can be done very quickly, for example in the millisecond range. In addition, only a small voltage is required to cause switching or maintaining a corresponding switching state.
  • the corresponding closure region is designed as a dimmable, electrochromic glass plate or as a dimmable, electrochromic glass panel.
  • a conductive polymer film is applied to the corresponding glass plate on one side. This changes its transparency depending on the voltage applied. In other words, when the supply voltage changes polarity, this closure region is switched over between the on-state and the off-state.
  • the corresponding visible surface can be handled separately and in particular be designed as an exchange module. This makes it possible in a simple manner, an exchange of the icon with variable display area or variable display areas. There is only one corresponding connection the closure areas for their control, for example on an existing lighting electronics or the like.
  • such a luminaire electronics is generally present at least for driving the luminous means within the luminaire, wherein according to the invention, the luminaire control can also be used to control the closure region or the closure regions. Since only a small supply voltage for a corresponding switching of the closure areas is required, the already supplied to the lamp or within the lamp supply voltage is usually sufficient and no additional measures to further power supply must be taken. However, it may be advantageous if an additional voltage control for controlling the different closure areas is provided, wherein this voltage control can be part of the lighting electronics or can be realized by the lighting electronics software. By the voltage control, a corresponding supply of the closure areas and the switching takes place.
  • closure region can be in the on-state switching state without activation.
  • the closure region is assigned to a region of the visible surface which may be larger than a corresponding arrow symbol or the like. Furthermore, there is the possibility that the corresponding closure region is formed congruent to a part of the pictogram or to the display region. That is, only a certain part of the icon or display area is permeable switched or blocked, this part may correspond, for example, the corresponding arrowhead. At the same time an arrow pointing in another direction arrowhead is used in the reverse manner, that is, for example, visible switched when the other arrowhead is switched invisible. There is also the possibility that an entire arrow is congruent with the closure area or other parts of an arrow. Accordingly, an arrow with a different direction indicator is respectively activated or deactivated.
  • the corresponding closure regions can be realized in different ways on or in the visible surface. It is conceivable, for example, that the closure region is designed as a closure field or panel. Such a closure panel or a corresponding panel can be arranged from the outside on the visible surface or even within this.
  • the corresponding display areas may also be part of the visible area or applied inside or outside.
  • the corresponding closure area is integrated in the visible area, i. H. is made in one piece with the visible surface.

  • this display area 4 is corresponding arranged on the visible surface 2 or formed by this. The arrangement can be made both on an outer side of the visible surface and on an inner side.
  • the luminaire 1 has a flat design and is an LED luminaire with a plurality of LEDs as the light source 9 along a lower light entry edge 11 of a light distribution plate 10. On one or both sides of the Lichtverteilplatte 10 corresponding viewing surfaces 2 are arranged with pictogram and display area.
  • the corresponding electronics are also arranged within the lamp 1. This electronics include, for example, a lighting electronics 15 and optionally an additional voltage control 16.
  • the light 1 can be connected via a cable or wirelessly with a central unit 18 in connection.
  • This central unit 18 is usually associated with a plurality of lights to perform, for example, a corresponding escape route control.
  • the corresponding central unit 18 can be used to control an emergency lighting system in which the lamp 1, in particular as a safety or escape sign light, is included.
  • the central unit 18 By means of the central unit 18 is also carried out a monitoring of the lamp 1 according to the standards or standards applicable in the emergency light area. Such an activation from the central unit 18 takes place, for example, via an address assigned to the luminaire 1. By means of this address, the light is accessible and controllable as well as monitorable or communicable with it.
  • the lamp 1 according to FIG. 1 is the corresponding display area 4 immutable.
  • the corresponding display area 4 can be changed, this being the case in the exemplary embodiments FIGS. 2a to 2c especially the arrow symbol shown together with the current person.

  • Each of these display areas 4 comprises an optical shutter area 5 and 6, respectively. These can be switched over electrically or electronically in order to transmit or essentially block light, depending on the switching state. For example, in FIG. 2a the optical shutter region 5 in the blocking switching state and therefore substantially opaque. The other optical shutter portion 6 is in the pass-through state, and therefore, the corresponding arrow symbol is recognizable as a direction indicator 7.
  • both optical shutter areas 5 and 6 are in the forward switching state, so that both arrow symbols or direction indicators 7 and 8 are visible.
  • This also corresponds to a possible switching state of the closure regions, in which, for example, lead at least from the point at which the corresponding lamp 1 is located within a building escape routes in both directions.
  • Figure 2c is analogous to FIG. 2a the other optical shutter portion 6 in the blocking switching state while the optical shutter portion 5 is in the on-state switching state.
  • D. h. The other direction indicator 8 with the corresponding arrow symbol is activated and marks the escape direction.

  • Such a material also referred to as LC glass, comprises a polymer-liquid-crystal film which is, for example, embedded between two thin glass panes and connected to a power source.
  • the liquid crystals are arbitrarily oriented in the solid polymer and are aligned only when a voltage is applied in a preferred direction. This alignment makes the glass transparent. When the voltage is removed, the opposite effect results and the LC glass becomes opaque again and thus opaque.
  • the corresponding voltages can be provided by the voltages already present within the luminaire 1. There are no additional measures required for the power supply. It may prove advantageous only if the already existing luminaire electronics 15 additionally has a voltage control 16, by means of which, for example, the corresponding switching states of the different optical shutter regions 5 and 6 can be realized.

  • the corresponding visible surface 2 is usually part of an outer wall of the lamp 1 or is formed directly by this.
  • the pictogram can be realized inside or outside of this outer wall as a separate part or as a coating on the outer wall.
  • closure regions In both embodiments of the closure regions described above, these can be designed as closure panels or panels 17. It is also possible that a corresponding closure area is integrated in the visible surface and thus is part of the visible surface.
  • FIGS. 3a to 3c are further embodiments of visible surfaces 2 with particular pictogram 3 or display areas 4 or direction indicators 7, 8 shown.
  • the representation of corresponding visible surfaces is not exhaustive, but only by way of example, wherein other pictograms, display areas and arrangements of closure areas are possible.
  • Corresponding direction indicators are arranged on one side or on both sides to a word "exit". Also with regard to these direction indicators is a switching through the optical described above Closure areas 5 and 6 possible. D. h., It can, for example, in the in FIG. 3a Above visible surface, the right-facing triangle are ineffective, for example, to identify a door located directly below this visible surface as an escape door. However, should this door not be usable, there is an escape route guidance by visual switching of the corresponding triangle. This applies analogously to the in FIG. 3a Pictured below, in addition, a selection between the two pointing to the left or right triangles can be made.
  • variable display areas which are formed in a simple manner by corresponding switchable optical shutter areas. These require essentially no conversion of the lamp, but can be powered by the existing lighting electronics and controlled. Also, no additional bulbs or power supplies are required, since the existing bulbs and the already existing power supply for the corresponding closure areas are sufficient.
  • the control of the lamp is thereby also simplified because, for example, no additional addresses for addressing additional facilities within the lamp are required, but the entire control via the existing means and addresses can optionally be done by a central unit forth. It is also no switching or dimming of bulbs required that serve, for example, the backlighting of the icon or the display areas. Instead, the bulbs can be operated in the usual way.
