Definitions
- the present invention relates to an emergency light with its own emergency power source and automatic, electronic switching and charging circuit.
- emergency lights with their own emergency power source of the aforementioned type are also state of the art (so-called single battery system).
- These known emergency lights are either designed as independent, individually mounted lights, or kits are used for installation within normal, mains-powered lights.
- the first case it is necessary to lay special power cables to each emergency light, which means a high additional installation effort.
- the second case the selection of luminaires that can be used is severely restricted, and the arrangement of the emergency luminaires is local, which means that they are always in the place of normal luminaires (e.g. on the ceiling), which often does not meet the requirements for safety or replacement lighting in the event of a power failure corresponds (display of an escape route in the building, lighting of workplaces with risk of accident, etc.).
- Emergency lights are also known ( FR-A-1 264 752 ) which have their own emergency power source and an automatic, electronic switching and charging circuit. These are designed as plug-in units and can be inserted into existing sockets. It is considered a disadvantage that such units can be replaced by unauthorized persons and that there is an increased security risk, which is not tolerable with emergency light arrangements.
- the aim of the invention is to avoid the disadvantages of the known designs mentioned and to create an emergency lighting system corresponding to increased safety requirements at a comparatively low cost and at to allow free choice of luminaire locations.
- This object is achieved according to the invention with an emergency light of the type mentioned at the outset with the features of claim 1.
- the emergency luminaires Thanks to such a design of the emergency luminaires, their assembly and arrangement can largely take place in the course of normal power line laying and apparatus installation, i.e. the emergency lights are preferably installed along the network installation to be created anyway and adjacent to sockets, light switches, junction boxes, etc.
- the built-in unit of the emergency light can therefore be connected to the external voltage (mains voltage) in an existing equipment box without additional installation effort.
- the low effort allows the installation of a larger number of emergency lights without any problems, which also enables a more uniform illuminance of the emergency light to be achieved.
- the built-in unit 10 is built on a printed circuit board 11 and contains in particular its own emergency power source - here consisting of two rechargeable cells 12 -, mains connection terminals 13 and a lamp holder 14 which is preferably arranged centrally on the printed circuit board 11. Otherwise, the printed circuit board 11 with the ones here is not switching elements of an automatic, electronic switching and charging circuit shown in detail according to the diagram of FIG. 4; In Fig. 1, only a light-emitting diode 16 as an operating display element and an operating switch 17 are visible from this circuit.
- the unit 10 is received for the installation by the insulating housing 6, which fits into the equipment box 1 and in particular serves to separate the unit 10 from mains cables which are laid in the bottom of the box 1.
- the unit 10 is connected to the mains through housing openings 8 at the terminals 13.
- the mechanical fastening is carried out, as with other built-in apparatus (light switch, socket, etc.), on the eyelets 4 of the mounting frame 3 which fits onto the flange 2 of the socket 1.
- the insulating housing 6 has For this purpose, two screw holes 7, and preferably two further holes 7 'fitting on the eyelets 4', so that the unit 10 can optionally be installed in two positions offset by 90 °.
- the cover 20 of the emergency light has the outer shape of a normal cover plate, as it is also used for switches and sockets, etc. for flush mounting.
- the shield has a light exit opening 21 which is aligned with the lamp holder 14, ie preferably in the center, through which a part of the bulb of the emergency lamp 15 projects.
- a further opening 22 next to the opening 21 is covered by a (partially broken away) dome light 23, which on Shield 20 is attached and consists of translucent, for example light-diffusing shaped material.
- the shield 20 and / or the dome 23 can be provided with a label or, for example, an escape route symbol or the like.
- the openings 21 and 22 can be arranged side by side or one above the other.
- the operating switch 17 is actuated only before the emergency light is installed and is inaccessible in the installed state.
- cover plate 20 in view.
- a combined cover plate 20 ' can of course be used if the emergency light is installed next to another device.
- the cover can e.g. in the case of more extensive apparatus combinations, it can also be part of a control panel or the like.
- FIG. 2 is a top view of the unit 10 that can be installed. As can be seen, it or its circuit board 11 can be prepared for surface mounting by means of screws 18. In that case, the associated luminaire cover is expediently designed with the outer dimensions of a surface-mounted apparatus housing, but with corresponding openings and a dome light (not shown).
- the circuit of a suitable electronic switching and charging circuit according to FIG. 4 is known per se, for which reason the mode of operation is only briefly explained below:
- the rectifier bridge G is connected to the AC network via series resistors by means of terminals 13. It normally generates a DC charging voltage for the emergency supply battery 12.
- the live LED 16 indicates normal operation.
- a control circuit with the npn transistor T1 and the pnp transistor T2 is set in such a way that T2 is blocked as long as the rectifier bridge G generates the charging voltage when the mains voltage is present.
- the lamp 15 then remains de-energized.
- the switch 17 in the circuit of the emergency power source (battery 12) remains during the entire operating period, i.e. since the installation and connection of the emergency light, closed; for this reason the switch should remain inaccessible. It only has one function during the storage period before installation: For reasons of functional reliability, it is advisable to connect the cells 12 firmly in the circuit (using a welded or soldered connection). The unit 10 is therefore already equipped with the cells 12 during manufacture.
- the switch 17 is opened after the cells 12 have been charged for the first time and is only closed after the emergency light has been connected and installed in order to establish the operational readiness.
- a pluggable or solderable contact bridge could be provided on the printed circuit board 11.
- Parts of the switching and charging circuit according to FIG. 4 can, of course, also be constructed as an integrated circuit (chip) instead of individual components (FIG. 2).
- the equipment box for surface or flush mounting which accommodates the unit 10, can also be designed to be drip-proof, splash-proof, water-jet-proof, water-tight or explosion-proof, depending on the requirements.

Abstract
Description
Die vorliegende Erfindung betrifft eine Notleuchte mit eigener Notstromquelle und automatischem, elektronischem Umschalt- und Ladekreis.The present invention relates to an emergency light with its own emergency power source and automatic, electronic switching and charging circuit.
Neben Notbeleuchtungsanlagen mit Gruppen- oder Zentralversorgung mehrerer Notleuchten sind auch "autonome" Notleuchten mit eigener Notstromquelle der vorgenannten Art Stand der Technik (sogen. Einzelbatterie-System). Diese bekannten Notleuchten sind entweder als selbständige, einzeln zu montierende Leuchten ausgebildet, oder es werden Bausätze zum Einbau innerhalb normaler, netzgespeister Leuchten verwendet. Im ersten Fall ist die Verlegung von besonderen Netzleitungen zu jeder Notleuchte erforderlich, was einen hohen zusätzlichen Installationsaufwand bedeutet. Im zweiten Fall ist die Auswahl der verwendbaren Leuchten stark eingeschränkt, und die Anordnung der Notleuchten ist ortsgebunden, d.h. sie befinden sich zwangsläufig immer an der Stelle der Normalleuchten (z.B. an der Decke), was oft nicht den Erfordernissen einer Sicherheits- oder Ersatzbeleuchtung bei Netzausfall entspricht (Anzeige eines Fluchtweges im Gebäude, Beleuchtung von Arbeitsplätzen mit Unfallgefahr usw.).In addition to emergency lighting systems with group or central supply of several emergency lights, "autonomous" emergency lights with their own emergency power source of the aforementioned type are also state of the art (so-called single battery system). These known emergency lights are either designed as independent, individually mounted lights, or kits are used for installation within normal, mains-powered lights. In the first case, it is necessary to lay special power cables to each emergency light, which means a high additional installation effort. In the second case, the selection of luminaires that can be used is severely restricted, and the arrangement of the emergency luminaires is local, which means that they are always in the place of normal luminaires (e.g. on the ceiling), which often does not meet the requirements for safety or replacement lighting in the event of a power failure corresponds (display of an escape route in the building, lighting of workplaces with risk of accident, etc.).
Es sind auch Notleuchten bekannt (FR-A- 1 264 752) die eine eigene Notstromquelle und einen automatischen, elektronischen Umschalt- und Ladekreis besitzen. Diese sind als steckbare Einheiten ausgeführt und lassen sich in vorhandene Steckdosen einfühen. Nachteilig wird dabei angesehen, dass sich solche Einheiten durch unautorisierte Personen auswechseln lassen, und dass damit ein erhöhtes Sicherheitsrisiko besteht, was bei Notleuchten-Anordnungen nicht tolerierbar ist.Emergency lights are also known ( FR-A-1 264 752 ) which have their own emergency power source and an automatic, electronic switching and charging circuit. These are designed as plug-in units and can be inserted into existing sockets. It is considered a disadvantage that such units can be replaced by unauthorized persons and that there is an increased security risk, which is not tolerable with emergency light arrangements.
Aus allgemeinen Beleuchtungseinrichtungen für Unterputz Montage (GB-A-1 098 560) ist ebenfalls modulartiger Aufbau von Lampenanordnungen mit Schalter und Netzanschluss, sowie zugehöriger Lichtaustrittsöffnung für den Einsatz verschiedener Lampengrössen bekannt. Grundsätzlich nachteilig bei solch modularem Aufbau ist hingegen die aufwendige technische Lösung, die sich in diesem Zusammenhang nur für absolut eindeutige Massenproduktion eignet.From general lighting devices for flush mounting ( GB-A-1 098 560 ) is also known modular construction of lamp arrangements with switches and power supply, as well as the associated light outlet opening for the use of different lamp sizes. On the other hand, the complex technical solution, which in this context is only suitable for absolutely unambiguous mass production, is fundamentally disadvantageous with such a modular structure.
Mit der Erfindung wird angestrebt, die erwähnten Nachteile der bekannten Ausführungen zu vermeiden und die Erstellung von erhöhtem Sicherheitsbedürfnis entsprechenden Notbeleuchtungsanlagen mit vergleichsweise geringen Kosten und bei freierer Wahl der Leuchtenstandorte zu ermöglichen. Diese Aufgabe wird mit einer Notleuchte der eingangs genannten Art erfindungsgemäss mit den Merkmalen des Anspruch 1 gelöst.The aim of the invention is to avoid the disadvantages of the known designs mentioned and to create an emergency lighting system corresponding to increased safety requirements at a comparatively low cost and at to allow free choice of luminaire locations. This object is achieved according to the invention with an emergency light of the type mentioned at the outset with the features of
Dank einer solchen Gestaltung der Notleuchten kann deren Montage und Anordnung weitgehend im Zuge der normalen Netz-Leitungsverlegung und Apparate-Installation erfolgen, d.h. die Notleuchten werden vorzugsweise entlang der ohnehin zu erstellenden Netzinstallation und benachbart zu Steckdosen, Lichtschaltern, Abzweigdosen usw. eingebaut. Die einbaubare Einheit der Notleuchte kann also ohne zusätzlichen Installationsaufwand in einer bereits vorhandenen Apparatedose an die Fremdspannung (Netzspannung) angeschlossen werden. Der geringe Aufwand erlaubt ohne weiteres das Anbringen einer grösseren Zahl von Notleuchten, wodurch sich auch eine gleichmässigere Beleuchtungsstärke des Notlichtes erreichen lässt.Thanks to such a design of the emergency luminaires, their assembly and arrangement can largely take place in the course of normal power line laying and apparatus installation, i.e. the emergency lights are preferably installed along the network installation to be created anyway and adjacent to sockets, light switches, junction boxes, etc. The built-in unit of the emergency light can therefore be connected to the external voltage (mains voltage) in an existing equipment box without additional installation effort. The low effort allows the installation of a larger number of emergency lights without any problems, which also enables a more uniform illuminance of the emergency light to be achieved.

Die Notleuchte nach Fig. 1, bestehend aus der Einheit 10, zugehöriger Abdeckung 20 und einem die Einheit 10 aufnehmenden Isoliergehäuse 6 ist zum Einbau in eine normale Unterputz-Apparatedose 1 mit Flansch 2 und Montagerahmen 3 bestimmt. Die einbaubare Einheit 10 ist auf einer Leiterplatte 11 aufgebaut und enthält insbesondere die eigene Notstromquelle - hier bestehend aus zwei wiederaufladbaren Zellen 12 -, Netzanschlussklemmen 13 und eine vorzugsweise mittig auf der Leiterplatte 11 angeordnete Lampenhalterung 14. Im übrigen ist die Leiterplatte 11 mit den hier nicht im einzelnen dargestellten Schaltelementen eines automatischen, elektronischen Umschalt- und Ladekreises gemäss Schema nach Fig. 4 bestückt; in Fig. 1 sind von diesem Schaltkreis lediglich noch eine Leuchtdiode 16 als Betriebs-Anzeigeorgan sowie ein Betriebsschalter 17 sichtbar.1, consisting of the
Die Einheit 10 wird für den Einbau vom Isoliergehäuse 6 aufgenommen, welches in die Apparatedose 1 passt und insbesondere zur Trennung der Einheit 10 gegenüber Netzleitungen dient, die im Boden der Dose 1 verlegt werden. Der Netzanschluss der Einheit 10 erfolgt durch Gehäuseöffnungen 8 hindurch an den Klemmen 13. Die mechanische Befestigung erfolgt wie bei anderen Einbauapparaten (Lichtschalter, Steckdose usw.) an den Oesen 4 des auf den Flansch 2 der Dose 1 passenden Montagerahmens 3. Das Isoliergehäuse 6 weist zu diesem Zweck zwei Schraubenbohrungen 7 auf, und vorzugsweise zwei weitere auf die Oesen 4 passende Bohrungen 7′, so dass die Einheit 10 wahlweise in zwei um 90° gegeneinander versetzten Lagen eingebaut werden kann.The
Die Abdeckung 20 der Notleuchte hat hier - bei Unterputz-Montage - die äussere Gestalt eines normalen Abdeckschildes, wie es auch für Schalter und Steckdosen usw. verwendet wird. Das Schild hat eine auf die Lampenhalterung 14 ausgerichtete, also vorzugsweise mittige Lichtaustrittsöffnung 21, durch welche ein Teil des Kolbens der Notlampe 15 hindurchragt. Entsprechend der Anordnung der Leuchtdiode 16 (Betriebsanzeige) auf der Einheit 10 befindet sich neben der Oeffnung 21 eine weitere Oeffnung 22. Beide Oeffnungen 21 und 22 sind von einer (teilweise weggebrochen gezeichneten) Lichtkuppel 23 überdeckt, die am Schild 20 befestigt ist und aus lichtdurchlässigem, z.B. lichtstreuend geformtem Material besteht. Das Schild 20 und/oder die Kuppel 23 könnnen mit einer Beschriftung oder z.B. einem Fluchtweg-Symbol oder dergleichen versehen sein. Je nach Erfordernis - und natürlich entsprechend der montierten Drehlage der Einheit 10 bzw. des Gehäuses 6 - können die Oeffnungen 21 und 22 nebeneinander oder übereinander angeordnet sein.The
Der Betriebsschalter 17 wird, wie weiter unten ausgeführt, nur vor der Montage der Notleuchte betätigt und ist im eingebauten Zustand unzugänglich.As explained further below, the
Die Fig. 3 zeigt das Abdeckschild 20 in Ansicht. Wie strichpunktiert angedeutet, kann selbstverständlich ein kombiniertes Abdeckschild 20′ verwendet werden, wenn die Notleuchte neben einem andern Apparat eingebaut wird. Die Abdeckung kann aber z.B. im Falle umfangreicherer Apparatekombinationen auch Bestandteil einer Schalttafel oder dergleichen sein.3 shows the
Die Fig. 2 ist die Draufsicht auf die einbaubare Einheit 10. Wie ersichtlich, kann diese bzw. deren Leiterplatte 11 für Aufputz-Montage mittels Schrauben 18 vorbereitet sein. In jenem Fall wird zweckmässig die zugehörige Leuchten-Abdeckung mit den äusseren Abmessungen eines Aufputz-Apparategehäuses, jedoch mit entsprechenden Oeffnungen und einer Lichtkuppel gestaltet (nicht dargestellt).FIG. 2 is a top view of the
Die Schaltung eines geeigneten elektronischen Umschalt- und Ladekreises nach Fig. 4 ist an sich bekannt, weshalb die Wirkungsweise nachstehend nur kurz erläutert wird: Die Gleichrichterbrücke G ist über Vorschaltwiderstände mittels Klemmen 13 an das Wechselstromnetz angeschlossen. Sie erzeugt normalerweise eine Lade-Gleichspannung für die Notversorgungs-Batterie 12. Dabei zeigt die unter Strom stehende Leuchtdiode 16 den Normalbetrieb an. Eine Steuerschaltung mit dem npn-Transistor T1 und dem pnp-Transistor T2 ist so eingestellt, dass T2 gesperrt ist, solange die Gleichrichterbrücke G bei vorhandener Netzspannung die Ladespannung erzeugt. Die Lampe 15 bleibt dann stromlos.The circuit of a suitable electronic switching and charging circuit according to FIG. 4 is known per se, for which reason the mode of operation is only briefly explained below: The rectifier bridge G is connected to the AC network via series resistors by means of
Wenn jedoch die Netzspannung und damit die Ladegleichspannung ausfällt, erlischt die Leuchtdiode 16, und der Transistor T2 wird leitend. Es fliesst dann Strom aus der Batterie 12 über die Lampe 15 und den Transistor T2, d.h. die Notbeleuchtung wird automatisch eingeschaltet. Der Schalter 17 im Stromkreis der Notstromquelle (Batterie 12) bleibt während der gesamten Betriebsdauer, d.h. seit dem Einbau und Anschluss der Notleuchte, geschlossen; der Schalter soll aus diesem Grund auch unzugänglich bleiben. Er hat nur eine Funktion während der Lagerdauer vor dem Einbau: Aus Gründen der Funktionssicherheit ist es zweckmässig, die Zellen 12 in der Schaltung fest (mittels Schweiss-oder Lötverbindung) anzuschliessen. Die Einheit 10 wird also bereits bei der Herstellung mit den Zellen 12 bestückt. Um eine Entladung der Zellen über die Schaltung während der Lagerung zu verhindern, wird der Schalter 17 nach erstmaliger Ladung der Zellen 12 geöffnet und erst nach dem Anschluss und Einbau der Notleuchte zwecks Erstellung der Betriebsbereitschaft geschlossen. Anstelle eines eigentlichen Schalters 17 könnte selbstverständlich auch lediglich eine steckbare oder einzulötende Kontaktbrücke auf der Leiterplatte 11 vorgesehen sein. Teile des Umschalt- und Ladekreises nach Fig. 4 können anstatt aus Einzelkomponenten aufgebaut (Fig. 2) natürlich auch als integrierte Schaltung (Chip) ausgeführt sein.However, if the mains voltage and thus the DC charging voltage fails, the light-
Die Apparatedose für Auf- oder Unterputzmontage, welche die Einheit 10 aufnimmt, kann je nach Erfordernis auch tropfwasser-, spritzwasser-, strahlwassersicher, wassderdicht oder explosionsgeschützt ausgeführt sein.The equipment box for surface or flush mounting, which accommodates the
