Disclosure of the invention

in the The invention provides a signaling device for signaling an escape route with the features of claim 1 and an escape route signaling system proposed with the features of claim 10. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims of the following description and the attached figures.

The Signaling device according to the invention is for Signaling an escape route, suitable and / or trained. Preferably, the signaling device is used to mark the escape route of persons from a source of danger, in particular before a fire.

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

The Signaling device is realized so that they are activated in one State represents a first direction information with a first color. The direction information is designed such that wegsuchende Persons at the signaling device read a direction or can derive. The representation with the first color takes place by or on the basis of an active lighting of the individual sources of light or a subset thereof.

in the According to the invention, it is proposed that the signaling device is formed, in the activated state, a second direction information with a second color, especially at the same time represent. The second direction information and the second color are analog formed to the first directional information and the first color, where the first and second colors differ in color.

Of the Advantage of the invention is that the wegsuchenden persons not Only one direction can be shown, which is used as an escape route shall be. In addition to this feature, it is possible either to show the pathfinder a direction they are not or third parties, for example rescue personnel or the fire department to point the direction to the danger area. These Dual function increases safety for those looking for a way out Persons and improves the orientation of the third party in the application.

at a particularly preferred embodiment is the first Color green and the second color red. These colors are internationally known as signal colors, so that the wegsuchenden Persons intuitively at the direction information with the green Orient the color and the direction, which by a red color is to be avoided. The third party can against it specifically use the direction information with the red color.

at a constructive implementation of the invention are the single light sources designed as LEDs, in particular high-power LEDs. In a further education The LEDs can be used as duo LEDs and / or OLEDs (organic Light emitting diodes) be realized, wherein in a single LEDs two different colors can be controlled. Instead of Duo LEDs can also each two LEDs with different Colors are positioned spatially adjacent. For others Further developments of the invention can be added more colors become. However, it is preferred - not least for reasons of cost - if the signaling device with the direction information with exactly outputs two colors.

in principle can single-light sources in any form be arranged, for example in concentric rings, like a matrix etc., with the output of the direction information optional only a part the individual sources of light is controlled. In a preferred Embodiment, the individual sources of light are band-like arranged. For operation, the signaling device fixed so that the extension direction of the band-like arrangement in or against the escape route points. In the band-like embodiment can also have several individual sources of light transversely to the extension direction be arranged side by side or offset from one another.

It in the context of the invention, that the directional information is static be issued so that the signaling device in the activated State constantly lit. In alternative embodiments The direction information can be dynamic and / or time varying be issued. For example, the direction information regular or irregular flashing.

at According to a preferred refinement, the signaling device is designed such that that in the activated state, a running light function is implemented, wherein by a time-controlled activation of the individual light sources for the people seeking refuge the impression arises one or more light sources would be in one direction run, the first direction information or the second direction information equivalent.

at a particularly interesting implementation or development of the invention the signaling device has means for generating a directed radiation of the individual sources of light. The radiation characteristic is chosen so that a part of the individual sources of light in a first solid angle region and a second part of the single light sources is directed into a second solid angle range, wherein first and second solid angle region is not formed overlapping are. Locally, each of the individual sources of light emits either in the first or in the second solid angle range. In an overall view the signal device results in a radiation characteristic, wherein z. B. in a plan view from above the first part of the individual light sources radiates in a first direction and a second part of the light sources radiates in a different direction, with the individual rays of the individual light sources Although in the immediate vicinity can cross, However, at some distance, there are two different solid angle ranges result. Preferably, the signaling device is designed such that all individual sources of light, their radiation characteristics in the first Solid angle area shows with the one color and that all single light sources, whose emission characteristic points into the second solid angle range blast with the other color.

By This structure is realized that the light of the individual sources of light to be seen only in certain solid angles. The signaling device is in this development is designed such that for the looking for people in a line of sight only the first color and to see only the second color in another direction is. In this development, it is therefore not necessary, the Signal device, for example, split in half and one half with the first color and the second half to illuminate with the second color. Instead, it becomes possible that depending on the position of the escape route seeker Persons relating to the signaling device and its direction of view on the signaling device in extreme cases, only the first Color or only the second color is shown. For other positions or other points of view of the person seeking escape the signaling device is position dependent with respect to the colors divided.

at a possible constructive realization of the invention the signal device has light-guiding and / or limiting Structures, for example, funnel-like in cross section through the signaling device Structures on which the solid angles of the radiation of the individual light sources limit.

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

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

Especially For buildings without smoke and heat exhaust can namely the problem occur that usual signaling devices arranged at ceiling height and thus in a smoke area are. It is therefore proposed that the signal device according to the invention near the ground, in particular at a height <1.80 m, to avoid occlusion by rising smoke.

The Escape route signaling system has, for example, a danger control center which, via a fieldbus system or another system associated with a plurality of hazard sensors and other actuators is. In the danger control center, the hazard sensor signals become the hazard sensors and in the case of a dangerous condition is stored, for example, by means of in the danger control center Escape route plans a dynamic control of the actuators and the at least one signaling device made.

Embodiment (s) of the invention

The 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 serves to avoid a hazard such. As a fire automated or detected by another alarm message and implement appropriate countermeasures, in particular an evacuation of those residing in the danger areas people. The evacuation takes place, among other things, by issuing directional information to the persons at risk.

The escape route signaling system 1 includes a danger control center 2 , Hazard sensors 3 , general actuators 4 and signaling devices 5 , which signaling technology with each other or via the alarm panel 2 are connected. The signaling connection can be realized for example via a fieldbus system. The topology of the signaling connection is arbitrary, so can the hazard sensors 3 , the actors 4 and the signaling device 5 can be controlled via the same fieldbus, alternatively different fieldbus stitches or rings can be used. It can also be another form of fieldbus for the hazard sensors 3 and the actors 4 or the signaling device 5 be used.

The danger control center 2 has a storage device 6 on, in which an escape route plan is filed, so that the danger control center 6 for a dynamic control of the actuators 4 and signaling devices 5 is trained. The signaling devices 5 The aim is to provide the refugees with information by means of optical signals in which direction they should go in order to safely leave the object, for example the building.

The 2 shows in a schematic three-dimensional representation of a room with a signaling device 5 as an embodiment of the invention, which via the escape route signaling system 1 is controlled. In the middle of the figure is a person seeking the escape route 7 on the ground 8th standing, which points to the signaling device 5 looks. 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 are a plurality of individual light sources 9 . 9a . 9b integrated, in the extension direction of the signaling device 5 are arranged side by side.

The single source of light 9 . 9a . 9b serve to indicate an escape direction 10 and a reverse direction 11 , In a very simple embodiment of the invention, the direction of escape 10 and the opposite direction 11 be indicated by a in the 2 left part of the single source of light 9a illuminated green and a right-hand part of the individual luminosity sources 9b is illuminated in red. Because of the signal colors green and red, the person knows 7 intuitively, that the escape route according to arrow 10 through the green single source of light 9a and the way to the sources of danger according to arrow 11 and / or in a non-recommended area by the red single light sources 9b is shown.

In a dynamic embodiment of the signaling device 5 become the individual light sources belonging to a color group, ie red or green 9a respectively. 9b controlled by a running light function. The implementation of the chase function is in the 3a and 3b illustrated as a table, the table according to 3a signaling the way in the direction of the arrow 11 and the 3b the signaling of the way in the direction of the arrow 10 represents. In the 3a "Runs" a light source in the 2 to the right, by activating the single source of light 9b is switched so that the "running light" in a time step 1 is activated in the position outside left. In a time step 2 this position is deactivated and the adjacent one on the right is activated. In the time step 3 the position of the "running light source" is shifted by one position to the right, etc. At the 3b The light source apparently "runs" to the left. In the in the 2 In the embodiment shown, in a dynamic embodiment, the red single light sources 9b according to the logic of 3a and the green single source of light 9a according to the logic of 3b driven.

It is also possible that single sources of light 9a . 9b one color is static and the other color is dynamic. For example, it makes sense that in the direction of escape 10 the single source of light 9a be operated running light and in the opposite direction 11 be controlled statically.

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

Should the direction information for the escape direction 10 or opposite direction 11 be reversed, so for example, designed as a duo LEDs single luminance sources 9a , b switched in color, so that then the single light sources 9b green and the single source of light 9a glow red. Alternatively, in each slot 12 two individual sources of light 9 with different colors or equally oriented manholes 12 with individual sources of light 9 be provided with different colors.

In the 5a and 5b are in a highly schematic representation of the individual sources of light 9b respectively. 9a illustrated, wherein the emission characteristic is illustrated as clubs. The limits of the lobes are defined, for example, by the fall in maximum light intensity to 50%. The club of the single source of light 9b is in escape route direction 10 and the club of the single source of light 9a in the opposite direction 11 oriented. In a band-like, alternating juxtaposition of the individual sources of light 9b respectively. 9a results in a Gesamtabstrahlcharakteristik, as schematized in plan view in the 6 is shown. In escape route direction 10 sees the person 7 in the field of vision I only the green single source of light 9a , In the opposite direction 11 in sight line II the person sees 7 against it only the red single light sources 9b ,
