Description

The The invention relates to an emergency light for illuminating a surrounding area in case of emergency or danger according to the generic term of claim 1.

Emergency Lights For lighting an environment in case of emergency or danger are in itself known facilities for private households or in the institutional area such as in hotels, hospitals or retirement homes or Like., In which a light source arranged in a room such is turned on and in case of power failure, that one in this Person in the room, despite the loss of power Orient the darkness and move into another safe area can change. In the private sector such emergency lights are often as so-called pluggable night lights also independent of power failures then used when at night dark rooms such as nursery or the like. be illuminated with a low residual brightness, for example to help children wake up at night. In this case, a corresponding lighting device is plugged into a socket and then lights up while In the darkness the room is weak.

Just in the institutional sector as in hospitals or nursing homes but the mere assurance of a lighting function in the case of a Power failure not sufficient to hedge there People. For one thing, it is not certain that such a simple emergency light even while the whole duration of the power failure works as these emergency lights only a limited and previously not reliably detectable lighting duration have in power-free emergency operation. It can therefore happen that such an emergency light is correctly in emergency mode, though the mains fails, but the lighting time only for a portion of the duration of the power failure is sufficient and therefore the emergency light function not sure assured is. Furthermore, it has been established that the operational safety Such emergency lights is given only very limited, since the batteries or batteries of the emergency lights are not regularly monitored and their state of charge therefore very inconsistent. Should a safe operation of emergency lights guaranteed are so elaborate and regular maintenance the emergency lights required, which is expensive and staff-intensive and In addition, regular access required to the installation sites. It is therefore quite often in nursing homes have come to situations where more or less helpless people due to power failure or due to there often executed at night maintenance at electrical installations in dangerous or embarrassing situations have come out of which they are due the lack of lighting or due to non-functioning Could not free call systems alone.

It give this for about the care sector solutions, where by means of specially installed equipment and wiring an emergency operation about of lighting units or signaling devices for the de-energized Condition over Backup batteries guaranteed but this can be costly individual installations are planned from the outset for the electrical installation Need to become.

Farther are the modern electrical installation technology different bus systems well-known, in those in the object area, but also for upscale households when reinstalling the electrical systems instead of normal cables so-called installation bus systems are laid, on the one hand, the power supply the individual devices takes place, but also a communication between the devices or with parent Enable stations. Emergency lighting can also be installed in such installation bus systems Various sensors are integrated, with which an intelligent room monitoring and room control possible becomes. The installation of such systems requires but usually a complete one Re-wiring of the electrical installation and replacement of all ECUs for electrical appliances such as sockets and switches, so that such a system, so to speak, only for the new building or the comprehensive renovation in old stock makes sense.

task The present invention is therefore an easy-to-install and to provide functionally modular emergency lighting, for a safe Emergency operation in de-energized state of the electrical installation safeguards and to take over additional monitoring functions can.

The solution the task of the invention arises from the characterizing features of claim 1 in Interaction with the characteristics of the generic term. Further advantageous Embodiments of the invention will become apparent from the dependent claims.

The invention is based on an emergency light for illuminating an environmental area in the event of an emergency or danger, which is connected to the power supply in normal operation and has at least one light-emitting device. Such a generic emergency light is further formed by the fact that the emergency light in a switch box or the like. Built-in receiving space is permanently installed and has sensors / actuators or connected to sensors / actuators with which monitoring and notification functions of the emergency light depending on environmental parameters are executable , where the emergency light is equipped with its own emergency power supply, which in case of failure of Mains voltage is activated and ensures the operation of the emergency light and / or at least one of its monitoring and notification functions. Significant advantage of the emergency light according to the invention is therefore on the one hand, the installation of emergency light in existing conventional switch boxes or otherwise usually in existing or provided installation space such as drainage boxes, mounting frames or the like., By one, the installation space is minimized and installation also in the building stock is simply made possible. Furthermore, the emergency light according to the invention can have sensors / actuators or be connected to sensors / actuators with which monitoring and notification functions of the emergency light can be performed depending on environmental parameters, so that the emergency light in addition to the pure lighting function can also take on other tasks that previously only were executable either with elaborate additional sensors / actuators and the necessary additional wiring. The emergency light according to the invention can also be used as an easily installable and cost-effective alternative to known installation bus systems, which indeed allow appropriate monitoring and notification functions, but this usually only by combining several separate individual modules, assuming the presence of the actual installation bus. In addition, it is ensured with the emergency light according to the invention that in addition to the pure emergency light function of the emergency light at least some of the integrated monitoring and notification functions can be ensured even in a power failure by the emergency power supply of the emergency light and the emergency power supply of the modules for the monitoring and notification functions takes over. This ensures that even in the event of a power failure, for example, for persons located in the vicinity of the emergency light, the security is ensured, but at least a dangerous condition is detected and signaled and thus appropriate countermeasure can be taken. With this combination of the functionalities of the emergency light according to the invention a substantial improvement in the applicability to conventional emergency lights is achieved with lower equipment and installation costs. But above all, such an emergency light can be easily integrated into existing electrical installations or connect with existing electrical installations, so that just the use in the building stock can be done inexpensively. In the sense described above, the emergency light also has a orientation function and could also be referred to as emergency and orientation light.

From It is advantageous if the emergency power supply of the emergency light has an energy storage device. Such energy storage device can during operation of the emergency light be charged continuously on the power grid, so that the functionality of the Emergency light is given at any time. Beyond that from the emergency light, the state of charge of the energy storage device preferably constantly monitored, For example, aging of the energy storage device can also be timely be recognized and signaled about such that an exchange of Energy storage device quickly and thus the functionality Emergency light remains permanently secured. For this it is in further Design useful if the energy storage device of Emergency light is self-exchangeable without dismantling the emergency light, preferably by one from outside of the emergency light Drive bay. This can not even professionally trained professionals the energy storage device easy and possibly even without special Simply replace the tool so that nursing staff working in a nursing home, for example signaling the necessity of replacing the energy storage device can replace the energy storage device directly on site. Also, it is conceivable additional to connect external energy storage devices with the emergency light, to increase the service life of the emergency light.

Conceivable it is also that the energy storage storage device alternatively for charging on the mains or in addition via a Solar module is loadable, which is integrated into the emergency light or with the emergency light is in electrical connection. This is a further safeguard of the function of the emergency light conceivable, that even with longer ones de-energized states the mains supply always over the solar module is recharged.

Of importance for the safety function of the emergency light is when the emergency power supply in case of interference or below a predefinable minimum light duration of the emergency light by emergency power supply outputs an error signal, preferably acoustically or visually signaled. It is important that the emergency light, for example, provides the emergency light function and the monitoring and notification functions independently of the status of the power grid in the event of a power failure over a definable time in order to protect persons located in the area of the emergency light, for example. By the emergency power supply constantly calculates and monitors the foreseeable due to the state of charge of the energy storage device minimum operating time, the system designer can safely specify and ensure the duration of the functioning of the emergency light. Should the state of charge of the energy storage device no longer guarantee the required duration of the currentless operation of the emergency light, this can be signaled in good time before an emergency operation and a premature failure of the emergency light, for example by exchanging the energy memory storage device counteracted. It is advantageous in this case if the signaling of a fault or falling below a predefinable minimum light duration by a magnetic contact is temporarily suppressed, preferably by a magnetic contact which is actuated by a magnet from outside the emergency light. As a result, for example, the nursing staff of a retirement home, which is made aware of the disturbance by the signaling of a disturbance, temporarily suppress this signaling, for example switching off a corresponding buzzer for a limited time until repair or replacement of the energy storage device. During this time, for example, the resident of the nursing home is not disturbed and, if necessary, maintenance personnel can be requested. It is important that the signal can be suppressed by the contact only for a limited time and then a renewed signaling, so that not safety-impaired by repeatedly suppressing the signaling the safety function of the emergency light is impaired or even canceled. It is also conceivable fault acknowledgment by a concealed switch, which is accessible only by means of a sharp object through a hole in the cover of the emergency light and whose function is known only to the nursing staff. With regard to checking the function of the emergency light, it is also advantageous if the emergency light after a connection to the mains power supply performs a test of the emergency power supply. This will detect any problems that have occurred and ensure trouble-free emergency operation.

From It is also an advantage if the function of the emergency light is appropriate the ambient brightness adjustable and / or on and off is formed, such as the emergency light is a photosensitive Has element with which the function of the emergency light of the ambient brightness is controllable accordingly. This can be about the lighting function be adapted to the emergency light of the respective brightness at the installation site or it can also monitoring and notification functions depending on the respective brightness be switched on or off or regulated at the installation.

Farther it is an advantage to whom the maximum duration of the emergency light, the above the energy storage device must be ensured at the emergency light is adjustable. This can be about when operating several such Emergency lights the required service life of the emergency light to the respective Installation location individually adapted to who, are also easy changes the needs The minimum duration of the emergency light can be easily changed on site.

This makes it possible to expand the scope of application and in particular the administration of such installation of emergency lights both in terms of effort manageable and cost-effective retrofit. Thus, alone with the help of such networked emergency lights a monitoring and notification function in a whole retirement home or the like. Can be built without complex modifications are required. Here, the communication of the individual emergency lights and / or the monitoring center via the wiring of the power grid can be done, for example by known techniques such as powerline transmission or the like. Transmission techniques are used, which remain functional even in the de-energized state of the cable networks. It is also conceivable to use a radio link between the emergency lights and / or the monitoring center as it is already known and tested in the networking of wireless smoke detectors. It can be provided that in such interconnections of several emergency lights a kind of diagnostic option is implemented in emergency, in which the quality of the connection of individual compounds of the emergency lights can be analyzed and examined for the presence of interference or misconduct. This is for troubleshooting and quality assurance in networking directly beneficial.

From Importance here is that in the monitoring center the signals every emergency light over one Coding or the like. With regard to their spatial assignment to the respective Emergency light are clearly identifiable. This can cause an accumulated message an emergency light are assigned directly to the respective emergency light and the auxiliary personnel are immediately provided with the information where help or a check is necessary. It is also conceivable that the monitoring center based the signals of the emergency light automatically initiates countermeasures that lead to a Serve as security for people staying in the vicinity of the emergency light. For example, in the event of a power failure by the emergency light An electrical device switched off on site otherwise, when the power returns in one go undefined operating state could.

From It is an advantage if the emergency light is also available on common installation bus systems connectable and with these bus systems information technology can be coupled. hereby can the emergency light according to the invention also in installation environments with an installation bus system be used, for. For example a simple extension or for Area where the installation bus system itself is not provided is. For this purpose, it is helpful if the emergency light to such Bus systems can log to directly on the emergency light the corresponding Configuration within the bus system to make. The same of course applies also for other connection options z. B. over Radio communications.

Regarding the foreseeable sensors or actuators connected to the emergency light itself can be provided or connected to the emergency light, there are many conceivable possibilities for using such sensors on or with the emergency light. Conceivable is about that the emergency light has a sensor for movement or with a sensor for Movements is connected, preferably an infrared motion detector or a radar motion detector that works on movements in the vicinity of the emergency light reacts and reports this to the emergency light. This allows the function dependent on the emergency light be controlled by movements in the environment of emergency light, such as Emergency light can only be switched on if a movement in the detection area is detected or the brightness of the emergency light can be regulated higher when a person is within the detection range of the motion detector. Also, the signal of the motion detector about to hedge physically limited People are being used by being checked whether movements were registered within certain periods of time and therefore the person is probably physically intact as well.

Farther A sensor can be provided which is designed to smoke or fire in the Environment of the emergency light reacts and reports this to the emergency light. hereby can in particular in networked inserts of emergency light to central Spot alarm to be resolved, if smoke or fire was detected. For single or few Emergency lights can also be used locally to give a warning sound be like traditional Smoke detectors usual is.
