Description

Die Erfindung betrifft eine Baugruppe für zumindest eine insbesondere explosionsgeschützte Leuchte aus wenigstens einer Lampe, einer Spannungsversorgungseinrichtung und einer Verbindungseinrichtung, welche miteinander und über die Verbindungseinrichtung mit einer externen Spannungsversorgung elektrisch verbindbar sind.The invention relates to an assembly for at least one lamp, in particular explosion-proof, comprising at least one lamp, a voltage supply device and a connection device which can be electrically connected to one another and to an external voltage supply via the connection device.

Aus der Praxis ist eine solche Baugruppe bekannt, die in einem Gehäuse Lampe, Spannungsversorgungseinrichtung und Verbindungseinrichtung aufweist, wobei die Verbindungseinrichtung eine aus dem Gehäuse nach aussen geführte Durchgangsverdrahtung umfasst. Die entsprechenden Teile sind innerhalb des Gehäuses in verschiedenster Weise elektrisch miteinander verbunden, wobei diese elektrischen Verbindungen nicht explosionsgeschützt sind, da bei der aus der Praxis vorbekannten Baugruppe der Explosionsschutz über ein bestimmtes Dichtungssystem und einen Verschlussmechanismus zwischen einem Grundgehäuse und einer Schutzwanne als Gehäuseteil gebildet ist.From the practice of such an assembly is known, comprising in a housing lamp, power supply device and connecting means, wherein the connecting means comprises a guided outwardly of the housing through-wiring. The corresponding parts are electrically connected to each other within the housing in a variety of ways, these electrical connections are not explosion-proof, since in the previously known from practice assembly of the explosion protection on a particular sealing system and a closure mechanism between a base housing and a protective cover is formed as a housing part.

Soll bei einer solchen Baugruppe zur Wartung oder Reparatur ein Teil, wie Lampe, Spannungsversorgungseinrichtung oder Verbindungseinrichtung repariert oder ersetzt werden, sind dazu spezielle Vorkenntnisse erforderlich, so dass nur geschultes Fachpersonal mit spezieller Zulassung für elektrische Anlagen in explosionsgefährdeten Bereichen die Wartung oder Reparaturen durchführen darf.If a part such as a lamp, power supply device or connecting device is to be repaired or replaced in such an assembly for maintenance or repair, special prior knowledge is required so that only trained specialist personnel with special approval for electrical systems in potentially explosive areas may carry out the maintenance or repairs.

Da gegebenenfalls nur eine geringe Anzahl eines solchen Fachpersonals zur Verfügung steht, kann die Wartung bzw. Reparatur gegebenenfalls nur verzögert oder in grösseren Zeitabständen durchgeführt werden. Ausserdem besteht trotz des geschulten Fachpersonals ein erhöhtes Risiko bei einer solchen Wartung oder Reparatur.Since possibly only a small number of such specialist personnel is available, the maintenance or repair may possibly be delayed or carried out at greater intervals. In addition, there is an increased risk of such maintenance or repair, despite the trained personnel.

US-A-5,534,664 offenbart eine explosionsgeschützte Umhüllung für Beleuchtungssysteme in explosionsgefährdeten Bereichen. Die Umhüllung dient sowohl zur Umhüllung elektronischer Bauteile, als auch zur Bildung einer Verbindung zum Leuchtmittel und zu einer Hüllröhre. US-A-5,534,664 discloses an explosion-proof enclosure for lighting systems in potentially explosive atmospheres. The envelope serves both to encase electronic components, as well as to form a connection to the light source and to an envelope tube.

Der Erfindung liegt die Aufgabe zugrunde, eine Baugruppe der eingangs genannten Art dahingehend zu verbessern, dass auch ohne spezielle Kenntnisse in einfacher und sicherer Weise eine Wartung einer entsprechenden Leuchte im explosionsgefährdeten Bereich durchgeführt werden kann, wobei gleichzeitig die Leuchte eine große Flexibilität hinsichtlich der Bestandteile der Baugruppe aufweist.The invention has for its object to improve an assembly of the type mentioned in that even without special knowledge in a simple and safe way maintenance of a corresponding lamp in the hazardous area can be performed, at the same time the lamp has great flexibility in terms of components Assembly has.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Erfindungsgemäß sind die verschiedenen Teile der Baugruppe als Einzelmodule ausgebildet, wie Lampenmodul, Spannungsversorgungsmodul und Verbindungsmodul, wobei diese Einzelmodule mittels explosionsgeschützter Verbindungselemente miteinander verbindbar sind. Dies gilt ebenfalls für die entsprechende Verbindung zwischen Verbindungsmodul und der externen Spannungsversorgung.According to the invention, the various parts of the assembly are formed as individual modules, such as lamp module, power supply module and connection module, these individual modules are connected to each other by means of explosion-proof connection elements. This also applies to the corresponding connection between the connection module and the external power supply.

Durch die Verwendung solcher Einzelmodule sind keine speziellen Erfordernisse an ein Gehäuse aus Grundgehäuse und Schutzwanne hinsichtlich Explosionsschutz gestellt, so dass beispielsweise die Schutzwanne ohne Spannungsabschaltung der Lampe demontiert und anschließend ein Einzelmodul zur Wartung oder Reparatur entnommen werden kann. Auch dies kann ohne Spannungsabschaltung erfolgen. Da die Erfordernisse bei der Montage oder Demontage, zur Wartung bzw. Reparatur einer solchen Leuchte gegenüber der vorbekannten Leuchte erheblich vereinfacht und sicherer durchführbar sind, ist speziell geschultes Fachpersonal nicht erforderlich. Statt dessen können die Module vor Ort und ohne spezielle Maßnahmen gewartet oder ausgetauscht werden.Due to the use of such individual modules, no special requirements are made of a housing comprising a base housing and a protective trough with regard to explosion protection, so that, for example, the protective trough can be dismantled without voltage cut-off of the lamp and subsequently a single module can be removed for maintenance or repair. Again this can be done without power off. Since the requirements in the assembly or disassembly, for maintenance or repair of such a lamp over the prior art light considerably simpler and safer feasible, specially trained professionals is not required. Instead, the modules can be serviced or replaced on site without special measures.

Insbesondere bei Leuchtstofflampen kann es in diesem Zusammenhang als vorteilhaft angesehen werden, wenn das Spannungsversorgungsmodul ein elektronisches Vorschaltgerät aufweist.Particularly in the case of fluorescent lamps, it can be considered advantageous in this context if the power supply module has an electronic ballast.

Je nach Erfordernis besteht außerdem die Möglichkeit, dass die Einzelmodule vor der Lampenmontage miteinander verbunden sind, wozu die entsprechenden explosionsgeschützten Verbindungselemente benutzt werden. Auf diese Weise kann die bereits zu einer Leuchte zusammengesetzte Baugruppe insgesamt gehandhabt werden und bei der Montage an der entsprechenden Stelle befestigt und mit der externen Spannungsversorgung verbunden werden.Depending on requirements, there is also the possibility that the individual modules are connected to each other before the lamp assembly, using the appropriate explosion-proof fasteners are used. In this way, the already assembled to a light assembly can be handled in total and attached during assembly at the appropriate location and connected to the external power supply.

Bei anderen Montagen kann es günstig sein, wenn die Einzelmodule während der Lampenmontage miteinander verbunden werden.For other assemblies, it may be beneficial if the individual modules are connected together during lamp assembly.

Die Verbindungselemente können in unterschiedlicher Weise ausgebildet sein, solange sie entsprechend explosionsgeschützt sind. Ein Beispiel für solche Verbindungselemente der Einzelmodule sind Steckverbinder. Solche Steckverbinder können direkt an den entsprechenden Einzelmodulen angeordnet sein, so dass im Wesentlichen die Einzelmodule aneinandergesteckt werden und dadurch beispielsweise nach ihrer Verbindung relativ stabil für weitere Handhabungen sind.The connecting elements can be designed in different ways, as long as they are appropriately explosion-proof. An example of such connectors of the individual modules are connectors. Such connectors can be connected directly to the corresponding individual modules can be arranged, so that essentially the individual modules are plugged together and thus are relatively stable for further handling, for example, after their connection.

Grundsätzlich besteht die Möglichkeit, zwischen bestimmten Einzelmodulen auch bestimmte Verbindungselemente vorzusehen. Dadurch kann beispielsweise verhindert werden, dass Einzelmodule miteinander verbunden werden, die nicht für bestimmte Bereiche beim Explosionsschutz geeignet sind, nur für bestimmte Spannungen geeignet sind oder dergleichen. Dazu können die entsprechenden Verbindungselemente beispielsweise kodiert sein, so dass nur solche mit passender Kodierung miteinander verbindbar sind.Basically, there is the possibility to provide certain fasteners between certain individual modules. This can be prevented, for example, that individual modules are connected to each other, which are not suitable for certain areas in the explosion protection, are only suitable for certain voltages or the like. For this purpose, the corresponding connecting elements can be coded, for example, so that only those with matching coding can be connected to one another.

Wenn solche Erfordernisse nicht notwendig sind, besteht die Möglichkeit, dass alle Verbindungselemente der Einzelmodule gleichartig aufgebaut sind. Dadurch kann beispielsweise ein Lampenmodul der einen Leuchte in einfacher Weise auch in eine andere Leuchte eingesetzt werden. Dies gilt analog für die anderen Einzelmodule.If such requirements are not necessary, there is the possibility that all the connection elements of the individual modules are of similar construction. As a result, for example, a lamp module of a lamp can be used in a simple manner in another lamp. This applies analogously to the other individual modules.

Um die Montage der Leuchte zu vereinfachen, kann zumindest ein Einzelmodul Befestigungsmittel zur Leuchtenmontage an Mast, Decke, Wand oder dergleichen aufweisen. Je nach Größe der Lampe besteht ebenfalls die Möglichkeit, das entsprechende Befestigungsmittel an bei oder mehr Einzelmodulen vorgesehen sind.In order to simplify the mounting of the luminaire, at least one individual module can have fastening means for luminaire mounting on a mast, ceiling, wall or the like. Depending on the size of the lamp, it is also possible to provide the corresponding fastening means on at or more individual modules.

Das Lampenmodul umfasst in der Regel nicht nur das eigentliche Leuchtmittel, sondern kann beispielsweise auch eine Reflektoreinrichtung aufweisen. Dabei wird das Leuchtmittel mit zugeordneter Reflektoreinrichtung direkt mit den anderen Einzelmodulen verbunden, wodurch die Montage vereinfacht ist.As a rule, the lamp module not only comprises the actual lighting means, but may, for example, also have a reflector device. In this case, the light source with associated reflector device is connected directly to the other individual modules, whereby the assembly is simplified.

Bei einem Ausführungsbeispiel können die Einzelmodule mit jeweils einem anderen Einzelmodul verbindbar sein, so dass beispielsweise ein Lampenmodul mit einem Spannungsversorgungsmodul und einem Verbindungsmodul zusammengesetzt wird, um die entsprechende Leuchte zu bilden.In one embodiment, the individual modules can each be connectable to another individual module, so that, for example, a lamp module is assembled with a power supply module and a connection module in order to form the corresponding lamp.

Es ist außerdem denkbar, dass zwei oder mehr Lampenmodule mit einem Spannungsversorgungsmodul und beispielsweise auch zwei oder mehr Spannungsversorgungsmodule mit einem Verbindungsmodul verbindbar sind. Dadurch erhält man eine größere Variation bei dem Leuchtenaufbau.It is also conceivable that two or more lamp modules with a power supply module and, for example, two or more power supply modules can be connected to a connection module. This gives a greater variation in the luminaire construction.

Bei bestimmten Leuchten kann es erforderlich sein, dass diese beispielsweise zusätzlich einen wiederaufladbaren Batteriesatz aufweisen, um im Falle einer Spannungsunterbrechung eine gewisse Notbeleuchtung durch die Leuchte aufrechtzuerhalten. Erfindungsgemäß kann es dabei als günstig angesehen werden, wenn die Baugruppe weiterhin ein mit wenigstens einem der anderen Einzelmodule verbindbares Notversorgungsmodul aufweist. Dieses Notversorgungsmodul enthält die wiederaufladbaren Batterien.For certain luminaires, it may be necessary, for example, to additionally have a rechargeable battery pack in order to maintain a certain amount of emergency lighting by the luminaire in the event of a power failure. According to the invention, it can be regarded as favorable if the module furthermore has an emergency supply module that can be connected to at least one of the other individual modules. This emergency supply module contains the rechargeable batteries.

Es besteht die Möglichkeit, dass die Einzelmodule direkt miteinander verbindbar sind, indem beispielsweise die Teile eines entsprechenden Steckverbinders so ausgebildet sind, dass sie in den entsprechenden Gehäusen der Module integriert sind. Auf diese Weise werden die Module im Wesentlichen direkt miteinander verbunden. Es besteht ebenfalls die Möglichkeit, dass Steckerteil und/oder Buchsenteil eines solchen Steckverbinders mit dem zugeordneten Einzelmodul über ein flexibles Kabel verbunden sind. Dadurch können die Einzelmodule in größerem Abstand zueinander angeordnet werden und es ergibt sich mehr Flexibilität bezüglich der relativen Anordnung solcher Einzelmdule.It is possible that the individual modules are directly connectable to each other, for example, by the parts of a corresponding connector are formed so that they are integrated in the corresponding housings of the modules. In this way, the modules are essentially connected directly to each other. There is also the possibility that plug part and / or socket part of such a connector are connected to the associated individual module via a flexible cable. This allows the individual modules are arranged at a greater distance from each other and there is more flexibility in the relative arrangement of such Einzelmdule.

Um ein Einzelmodul im Prinzip in Reihe zwischen zwei andere Einzelmodule zu verschalten, können einem solchen Einzelmodul zumindest ein Steckerteil und ein Buchsenteil verschiedener Steckverbinder zugeordnet sein.To interconnect a single module in principle in series between two other individual modules, such a single module at least one plug part and a socket part of different connectors can be assigned.

Um mehr Optionen beim Lampenmodul zu erhalten, kann dieses aus verschiedenen Untermodulen zusammensetzbar sein. Beispiele für solche Untermodule sind ein Reflektormodul, ein Schutzwannenmodul und dergleichen. Diese entsprechenden Untermodule können zusammen mit einer oder mehreren Lampen zu dem entsprechenden Lampenmodul zusammengesetzt werden. Um auch in diesem Zusammenhang auf spezielle Anforderungen zur Verbindung der Untermodule zu verzichten, können diese durch entsprechende explosionsgeschützte Steckverbinder miteinander verbindbar sein. Dies gilt insbesondere für den Steckverbinder zur Verbindung einer Lampe mit Reflektor- und/oder Schutzwannenmodul.To get more options with the lamp module, this can be composed of different sub-modules. Examples of such sub-modules are a reflector module, a protective well module and the like. These respective sub-modules can be assembled together with one or more lamps to the corresponding lamp module. In order to dispense with special requirements for connecting the sub-modules in this context, they can be connected to each other by appropriate explosion-proof connectors. This is especially true for the connector for connecting a lamp with reflector and / or protection tank module.

Um ein entsprechendes Kabel aus einem Einzelmodul oder Untermodul für einen Steckverbinder herausführen zu können, kann ein Teil des Steckverbinders mittels einer explosionsgeschützten Verschraubung am Einzel- oder Untermodul befestigt sein.To be able to lead out a corresponding cable from a single module or submodule for a connector, a part of the connector can be attached by means of an explosion-proof screw on the single or submodule.

Im Folgenden werden vorteilhafte Ausführungsbeispiele der Erfindung anhand der in der Zeichnung beigefügten Figuren näher erläutert.In the following advantageous embodiments of the invention will be explained in more detail with reference to the accompanying figures in the drawing.

In Figur 1 ist eine Prinzipdarstellung einer Baugruppe 1 für eine Leuchte 2 aus einer Anzahl von Einzelmodulen dargestellt. Diese Einzelmodule sind ein Lampenmodul 7 mit der eigentliche Lampe 3, ein Spannungsversorgungsmodul 8 als Spannungsversorgungseinrichtung 4 und ein Verbindungsmodul 9 als Verbindungseinrichtung 5 zu einer beispielsweise externen Spannungsversorgung 6. Die Einzelmodule sind alle separat handhabbar und zur Wartung oder Reparatur austauschbar. Zur Verbindung der Einzelmodule sind zwischen diesen entsprechende Verbindungseinrichtungen, wie beispielsweise Steckverbinder 13 angeordnet. Da die entsprechende Leuchte 2 in explosionsgefährdeten Bereichen eingesetzt wird, sind diese Steckverbinder 13 als Verbindungseinrichtungen explosionsgeschützt mit entsprechender Zündschutzart, wie druckfeste Kapselung, erhöhte Sicherheit oder dergleichen ausgebildet.In FIG. 1 is a schematic diagram of an assembly 1 for a light 2 of a number of individual modules shown. These individual modules are a lamp module 7 with the actual lamp 3, a power supply module 8 as a power supply device 4 and a connection module 9 as a connection device 5 to an example external power supply 6. The individual modules are all separately handled and interchangeable for maintenance or repair. For connecting the individual modules are between these corresponding connection means, such as connectors 13 are arranged. Since the corresponding luminaire 2 is used in potentially explosive areas, these connectors 13 are used as connecting devices explosion-proof with the appropriate type of protection, such as flameproof enclosure, increased security or the like.

Die Einzelmodule sind ebenfalls so ausgebildet, dass sie in explosionsgefährdeten Bereichen einsetzbar sind.The individual modules are also designed so that they can be used in potentially explosive areas.

Durch die Verwendung solcher Einzelmodule und der entsprechenden Verbindungseinrichtungen zwischen diesen besteht die Möglichkeit, dass auch im Prinzip "Laien" ein solches Einzelmodul ohne Spannungsabschaltung entfernen oder durch ein anderes ersetzen können. Es besteht nicht die Notwendigkeit, dass dies durch speziell qualifiziertes Fachpersonal durchgeführt wird. Das heißt, ein Austausch eines entsprechenden Moduls kann während des Betriebs und ohne besondere Vorkenntnisse erfolgen.By using such individual modules and the corresponding connection devices between them, there is the possibility that also in principle "layman" can remove such a single module without voltage cut-off or replace it with another one. There is no need for this to be done by specially qualified personnel. That is, an exchange of a corresponding module can be done during operation and without any special knowledge.

Das in Figur 1 dargestellte Lampenmodul 7 enthält bereits eine Reflektoreinrichtung 21 und an diesem Einzelmodul wie auch am Spannungsversorgungsmodul 8 sind Befestigungsmittel 15 zur Montage der Leuchte und damit der gesamten Baugruppe 1 an beispielsweise einem Mast, einer Decke, einer Wand oder dergleichen vorgesehen.This in FIG. 1 illustrated lamp module 7 already contains a reflector device 21 and on this single module as well as the power supply module 8 fastening means 15 for mounting the lamp and thus the entire assembly 1 are provided on, for example, a mast, a ceiling, a wall or the like.

Die Befestigungsmittel 15 können an jedem Einzelmodul oder auch nur an einem Einzelmodul vorgesehen sein, wobei die Anordnung der Befestigungsmittel vom Gewicht der gesamten Baugruppe 1 und von Ort und Art der Befestigung abhängen.The fastening means 15 can be provided on each individual module or else only on a single module, the arrangement of the fastening means depending on the weight of the entire assembly 1 and on the location and type of fastening.

Weiterhin besteht die Möglichkeit, dass als weiteres Einzelmodul oder gegebenenfalls auch als Teil eines anderen Einzelmoduls ein Notversorgungsmodul 16 mit insbesondere wiederaufladbaren Batterien oder Akkumulatoren verwendet wird. Dieses dient bei Ausfall der externen Spannungsversorgung zur Notbeleuchtung mittels der Leuchte 2.Furthermore, there is the possibility that an emergency power supply module 16 with in particular rechargeable batteries or accumulators is used as a further individual module or possibly also as part of another individual module. This serves in case of failure of the external power supply for emergency lighting by means of the lamp 2.

In den Figuren 2a) bis 2d) sind verschiedene Ausführungsbeispiele insbesondere für Lampenmodule 7 dargestellt.In the FIGS. 2a) to 2d) different embodiments are shown in particular for lamp modules 7.

In Figur 2a) ist das Lampenmodul 7 mit einer Leuchtstofflampe als Leuchtmittel ausgebildet. Diese ist zur Verbindung mit einem weiteren Einzelmodul, wie Spannungsversorgungsmodul 8 oder Verbindungsmodul 9 mit einem Steckerteil 10 als Verbindungselement ausgebildet. Dieses Steckerteil 10 ist über ein flexibles Kabel 17 mit dem Lampenmodul 7 verbunden.In FIG. 2a ), the lamp module 7 is formed with a fluorescent lamp as a light source. This is for connection to a further individual module, such as power supply module 8 or connection module 9 with a plug part 10 as a connecting element educated. This plug part 10 is connected via a flexible cable 17 to the lamp module 7.

Analoge Leuchtmittel sind in Figuren 2b) bis 2d) dargestellt. Insbesondere in den Figuren 2c) und 2d) sind mehrere Lampenmodule 7 mit einem entsprechenden Spannungsversorgungsmodul 8 über ein zugeordnetes Steckerteil 10 verbunden.
