The invention relates to a signaling device for signaling an escape route with a plurality of individual light sources, wherein the signaling device is designed to represent a first direction information with a first color in an activated state. The invention further relates to a flight path signaling system with this signaling device.

In larger buildings, it is common or even required that escape routes, which should be used in the event of a fire or other sources of danger of persons identified by appropriate signs or signaling devices. Such signaling devices are permanently illuminated in some embodiments, in other embodiments they are illuminated only when a dangerous situation occurs.

The publication DE 10 2005 021736 A1 relates, for example, to a device for controlling rescue measures, wherein sensors are arranged in a region accessible to the persons, which locate the person, and wherein the sensors are connected to a computer, which consists of the localization of the person, the properties of the area and the location determined at least one source of danger of rescue operations. As a rescue measure, for example, the evacuation of persons is called, which is implemented in particular by guiding on escape routes, instruction to rescue teams or technical measures, such as closing and opening fire doors.

The publication EP 1 408 466 A1 relates to a method and a hazard detector for signaling an escape route and is probably the closest prior art. The document discloses a danger detector which, in addition to the usual equipment for triggering a hazard alarm, has illuminable arrows pointing away from one another and which can be controlled via a control panel. In the event of danger, the arrow is illuminated, which leads away from the source of danger or corresponds to the current escape route.

Disclosure of the invention

In the context of the invention, a signaling device for signaling an escape route with the features of claim 1 and an escape route signaling system with the features of claim 10 is proposed. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims of the following description and the accompanying drawings.

The signaling device according to the invention is suitable for signaling an escape route, and / or formed. Preferably, the signaling device is used to mark the escape route of people from a source of danger, especially from a fire.

The signal device has a plurality of individual light sources, wherein the individual light sources are preferably arranged at a distance from one another and / or are formed as discrete light sources and / or not as a luminescent screen, in particular not as a TFT or CRT screen.

The signaling device is realized in such a way that, in an activated state, it represents first direction information with a first color. The direction information is designed in such a way that persons searching for the path can read off or derive a direction of travel at the signal device. The representation with the first color is made by or on the basis of an active lighting of the individual light sources or a subset thereof.

In the context of the invention, it is proposed that the signal device is designed to display a second direction information with a second color, in particular at the same time, in the activated state. The second direction information and the second Color are formed analogous to the first directional information and the first color, wherein the first and second color differ in hue.

The advantage of the invention is that the people searching for a way out can not only be shown a direction that should be used as an escape route. In addition to this function, it is possible either to indicate to the evictors a direction in which they should not go, or to point the direction of the danger to others, for example rescue personnel or the fire brigade. This dual function increases the security for those seeking to move away and improves the orientation of the third party in the case of use.

In a particularly preferred embodiment, the first color is green and the second color is red. These colors are internationally known as signal colors, so that the people searching for the path intuitively orientate themselves to the direction information with the green color and avoid the direction which is marked by a red color. By contrast, the third parties can specifically use the direction information with the red color.

In a constructive implementation of the invention, the individual light sources are designed as LEDs, in particular high-power LEDs. In a development, the LEDs can be realized as duo LEDs and / or OLEDs (organic light emitting diodes), it being possible to control two different colors in a single LED. Instead of duo LEDs, two LEDs with different colors can also be positioned spatially adjacent. In other developments of the invention, other colors can be added. However, it is preferred - not least for reasons of cost - if the signaling device outputs the direction information with exactly two colors.

In principle, the individual luminous sources can be arranged in any desired form, for example in concentric rings, in a matrix-like manner, wherein optionally only a part of the individual luminous sources is driven to output the direction information. In a preferred embodiment, the individual light sources are arranged like a ribbon. For operation, the signaling device is attached so that the extension direction of the band-like arrangement points in or against the escape route. In the band-like embodiment, a plurality of individual light sources may also be arranged side by side or offset relative to one another transversely to the extension direction.

It is within the scope of the invention that the direction information is output statically, so that the signal device is constantly lit in the activated state. In alternative embodiments, the direction information may be output dynamically and / or time varying. For example, the direction information may be displayed flashing regularly or irregularly.

In a preferred embodiment, the signaling device is designed so that a running light function is implemented in the activated state, the impression is created by a time-controlled activation of the individual luminous sources for the refugees seeking people, one or more light sources would run in a direction corresponding to the first direction information or the second direction information corresponds.

In a particularly interesting implementation or development of the invention, the signaling device has means for generating a directional radiation of the individual light sources. The radiation characteristic is selected such that a part of the individual light sources is directed into a first solid angle region and a second part of the single light sources into a second solid angle region, wherein the first and second solid angle regions are not formed overlapping. Locally, each of the individual sources of light radiates either into the first or the second solid angle range. In an overall view of the signaling device results in a radiation characteristic, wherein e.g. in a plan view from above, the first part of the single luminous sources radiates in a first direction and a second part of the luminous sources radiates in a different direction, wherein the individual beams of the individual luminous sources in the immediate vicinity can indeed intersect, however, at some distance, there are two different solid angle ranges , Preferably, the signal device is designed so that all individual luminous sources, whose emission characteristic in the first solid angle range shows with the one color and that all single luminance sources whose emission characteristic in the second solid angle range shows emitting with the other color.

By this construction, it is realized that the light of the single luminous sources can be seen only in certain solid angles. The signaling device is formed in this development is such that only the first color and in a different direction only the second color can be seen for the wegsuchenden people in a viewing direction. at This development, it is therefore not necessary to share the signal device, for example, in half and to illuminate the one half with the first color and the second half with the second color. Instead, it is possible that in extreme cases, only the first color or only the second color is shown depending on the position of the escape route searching persons with respect to the signaling device and its viewing direction to the signaling device. In other positions or other directions of view of the escape route seeker, the signal device is divided in terms of position depending on the colors.

In a possible structural realization of the invention, the signal device has light-guiding and / or limiting structures, for example in the cross section through the signal device funnel-like structures, which limit the solid angle of the radiation of the individual light sources.

To facilitate the installation of the signaling device, this can be integrated in another functional unit, such as a decorative band, a carpet strip, a bumper strip or the like. It is even possible that the signal device is used in the non-activated state for illumination purposes.

The invention also relates to an escape route signaling system with a signaling device as described above, or according to one of the preceding claims, wherein at least one of the signaling devices is arranged near the ground.

In particular, in buildings without smoke and heat vent, namely, the problem may occur that conventional signal devices are arranged at ceiling height and thus in a smoke area. It is therefore proposed to attach the signal device according to the invention near the bottom, in particular at a height <1.80 m, in order to avoid occlusion by rising smoke.

The emergency exit signaling system has, for example, a security alarm center, which is connected via a fieldbus system or another system with a plurality of hazard sensors and further actuators. In the alarm control panel, the hazard sensor signals of the hazard sensors are evaluated and in the case of a dangerous condition, for example, based on in the alarm center deposited escape route plans made a dynamic control of the actuators and the at least one signaling device.

Embodiment (s) of the invention

The FIG. 1 shows a schematic representation of an escape route signaling system 1 for a building, a building complex, public spaces or the like as an embodiment of the invention. The escape route signaling system 1 is used to detect a hazard, such as a fire automated or another alarm message and appropriate To implement countermeasures, in particular an evacuation of persons staying in the danger areas. The evacuation takes place, among other things, by issuing directional information to the persons at risk.

The escape route signaling system 1 comprises a hazard warning center 2, hazard sensors 3, general actuators 4 and signaling devices 5, which are connected to each other by signal technology or via the hazard warning center 2. The signaling connection can be realized for example via a fieldbus system. The topology of the signaling connection is arbitrary, the hazard sensors 3, the actuators 4 and the signaling device 5 can be controlled via the same fieldbus, alternatively, different fieldbus stitches or - rings can be used. It is also possible to use another form of fieldbus for the hazard sensors 3 and the actuators 4 or the signal device 5.

The security control center 2 has a storage device 6, in which an escape route plan is stored, so that the security control center 6 is designed for dynamic activation of the actuators 4 and signal devices 5. The signaling devices 5 are intended to provide the refugees with information on the basis of optical signals in which direction they should go in order to safely leave the object, for example the building.

The FIG. 2 shows a schematic three-dimensional representation of a room with a signaling device 5 as an embodiment of the invention, which is controlled by the escape route signaling system 1. In the middle of the figure, a person looking for the escape route 7 is shown standing on the floor 8, which looks at the signaling device 5. The signaling device 5 is formed as a band and implemented in this embodiment as a design or impact protection strip. In the signaling device, a plurality of individual light sources 9, 9a, 9b are integrated, which are arranged side by side in the extension direction of the signal device 5.

The individual light sources 9, 9a, 9b are used to display an escape direction 10 and an opposite direction 11. In a very simple embodiment of the invention, the escape direction 10 and the opposite direction 11 can be displayed by a in the FIG. 2 the left part of the individual luminous sources 9a is illuminated green and a right part of the individual luminous sources 9b is illuminated red. Due to the signal colors green and red white the person 7 intuitively that the escape route according to arrow 10 by the green single light sources 9a and the route to the sources of danger according to arrow 11 and / or in a non-recommended area by the red single light sources 9b is displayed.

In a dynamic embodiment of the signaling device 5 belonging to a color group, ie red or green, individual light sources 9 a and 9 b are driven with a running light function. The implementation of the chase function is in the Figures 3 a and 3b illustrate as a table, the table according to FIG. 3 a signaling the route in the direction of arrow 11 and the FIG. 3b the signaling of the path in the direction of arrow 10 represents. In the FIG. 3a "runs" a light source in the FIG. 2 to the right, by switching the activation of the individual light sources 9b so that the "current light source" is activated in a time step 1 in the position outside left. In a time step 2, this position is deactivated and the adjacent one to the right is activated. In the time step 3, the position of the "running light source" is again shifted by one position to the right, etc. In the case of FIG. 3b the light source apparently "runs" to the left. In the in the FIG. 2 In the exemplary embodiment shown, in a dynamic embodiment, the red single luminous sources 9b according to the logic of FIG FIG. 3a and the green single luminous sources 9a according to the logic of FIG. 3b driven.

It is also possible that individual light sources 9a, 9b of one color are operated statically and those of the other color are operated dynamically. For example, it makes sense that in the escape direction 10, the individual light sources 9a are operated like a running light and are controlled statically in the opposite direction 11.

The FIG. 4 shows a development of the embodiment, as for example in the signaling device 5 of FIG. 2 can be used, in a sectional view from above through the signaling device 5, wherein the individual light sources 9a, b are each shown as LEDs. Each of the individual light sources 9a, b is arranged in a shaft 12, which is designed such that the radiation of the individual light sources 9a, b is limited in each case to a solid angle range <45 °, preferably <30 °. The solid angle range restriction is preferably performed only in one to the bottom 8 ( FIG. 2 ) parallel plane. The solid angles are oriented so that all individual luminous sources 9b with a red color in the direction of escape 10 and single luminous sources 9a with a green color in the opposite direction 11 shine. Through this Restriction of the solid angle of the individual luminous sources 9a, b sees the person 7 when looking in the direction of escape 10 only green luminous individual luminous sources 9a and in a view in the opposite direction 11 only red luminous single luminous sources 9b.

If the direction information for the escape direction 10 or opposite direction 11 is to be reversed, the individual light sources 9a, b designed as duo LEDs, for example, are switched in color so that the individual light sources 9b are green and the individual light sources 9a are red. Alternatively, in each well 12, two individual light sources 9 with different colors or equally oriented wells 12 with individual light sources 9 with different colors may be provided.

In the FIGS. 5a and 5b are the single luminous sources 9b and 9a shown in a highly schematic representation, wherein the radiation characteristic is illustrated as clubs. The limits of the lobes are defined, for example, by the fall in maximum light intensity to 50%. The lobe of the single luminous source 9b is oriented in the escape direction 10 and the lobe of the single luminous source 9a in the opposite direction 11. In a band-like, alternating stringing together of the individual light sources 9b and 9a results in a Gesamtabstrahlcharakteristik as schematized in plan view in the FIG. 6 is shown. In escape route direction 10, the person 7 sees in the sighting area I only the green individual light sources 9a. In contrast, in the opposite direction 11 in the viewing direction range II, the person 7 only sees the red individual light sources 9b.
