Description

Die Erfindung betrifft eine Leuchte mit einem Zusatzelement in Form eines Notlichtelements und/oder eines Sende- bzw. Empfangselements zum Senden und/oder Empfangen elektromagnetischer Strahlung.The invention relates to a luminaire with an additional element in the form of an emergency light element and / or a transmitting or receiving element for transmitting and / or receiving electromagnetic radiation.

Eine derartige Leuchte in Form einer Deckeneinbauleuchte mit einem Notlichtelement wird von der Anmelderin unter der Bezeichnung "Mildes Licht V" vertrieben. In Fig. 6 ist eine perspektivische Ansicht von schräg unten auf diese Leuchte skizziert. Die Leuchte weist ein Rahmenelement 400 auf, sowie ein lichtdurchlässiges Abdeckelement 200, das in drei Bereiche aufgeteilt ist. Im mittleren Bereich erkannt man das Notlichtelement 500. Nach oben hin, also in dem zum Einbau vorgesehenen Bereich, weist die Leuchte eine (in der Figur nicht gezeigte) nach unten offene Leuchtenwanne auf, die sich im Wesentlichen allseits bis zu dem Rahmenelement 400 hin erstreckt und in der die wesentlichen Bauteile der Leuchte, also beispielsweise eine Lichtquelle angeordnet sind.Such a lamp in the form of a recessed ceiling luminaire with an emergency light element is sold by the applicant under the name "Mild Light V" . In Fig. 6 is a perspective view of obliquely down on this light sketched. The luminaire has a frame element 400, as well as a translucent cover element 200, which is divided into three areas. In the middle region, the emergency light element 500 is recognized. Towards the top, that is to say in the area intended for installation, the luminaire has a downwardly open luminaire trough (not shown in the figure) which extends substantially all the way to the frame element 400 and in which the essential components of the lamp, so for example a light source are arranged.

Das Notlichtelement 500 ist im Vergleich zu dem Rahmenelement 400 klein, so dass man von einem "Notlichtauge" sprechen kann.The emergency light element 500 is small compared to the frame element 400, so that one can speak of an "emergency light eye".

Das Notlichtauge ist für den Fall vorgesehen, dass die Stromversorgung, mit der die Leuchte regulär betrieben wird, unterbrochen ist. In diesem Fall wird durch das Notlichtauge eine gewisse Grundbeleuchtung bzw. Notbeleuchtung sichergestellt. Dementsprechend ist zur Stromversorgung des Notlichtauges eine separate Stromquelle, beispielsweise in Form eines Akkumulators, vorgesehen. Bei der Lichtquelle des Notlichtauges handelt es sich um eine LED-Lichtquelle.The emergency light eye is provided in the event that the power supply, with which the lamp is operated regularly, is interrupted. In this case, the emergency light eye ensures a certain level of basic lighting or emergency lighting. Accordingly, a separate power source, for example in the form of a rechargeable battery, is provided for the power supply of the emergency light eye. The light source of the emergency light eye is an LED light source.

Das Notlichtauge ist im Bereich des Abdeckelements 200 angeordnet, derart, dass das von der LED-Lichtquelle erzeugte Licht durch das Abdeckelement 200 hindurch nach unten abgegeben wird, um so die Notbeleuchtung zu gewährleisten.The emergency light eye is arranged in the region of the cover element 200, such that the light generated by the LED light source is emitted through the cover element 200 downwards so as to ensure the emergency lighting.

Das Abdeckelement 200 wird durch mehrere plattenartige Elemente gebildet, die übereinander geschichtet angeordnet sind. Bei dem untersten Element handelt es sich um eine glasklare Abdeckung. Die darüber liegenden Elemente weisen im Bereich des Notlichtauges jeweils eine Ausnehmung auf, die etwas größer bemessen ist, als der entsprechende Umfang des Notlichtauges. Das Notlichtauge ist derart angeordnet, dass es von oben her in diese Ausnehmungen teilweise eingreift und sich nach unten hin zumindest im Wesentlichen bis zu der glasklaren Abdeckung hin erstreckt. Das Licht der LED-Lichtquelle des Notlichtauges durchsetzt also lediglich die glasklare Abdeckung, bevor es die Leuchte nach unten hin verlässt.The cover member 200 is formed by a plurality of plate-like members which are stacked on each other. The lowest element is a crystal clear cover. The overlying elements have in the region of the emergency light eye in each case a recess which is dimensioned slightly larger than the corresponding circumference of the emergency light eye. The emergency light eye is arranged such that it partially engages from above into these recesses and extends downwardly at least substantially up to the crystal-clear cover. The light from the LED light source of the emergency light eye thus only penetrates the crystal-clear cover before it leaves the light at the bottom.

Ein einfaches Einlegen des Notlichtauges in die Ausnehmungen ist nicht praxistauglich, weil das Notlichtauge bei einem Kippen der Leuchte, beispielsweise während eines Transports der Leuchte, herausfallen könnte. Deshalb ist das Notlichtauge mittels eines Blechbügels an der Leuchtenwanne bzw. an dem Rahmenelement befestigt.A simple insertion of the emergency light eye in the recesses is not practical, because the emergency light eye could fall out when tilting the lamp, for example, during transport of the lamp. Therefore, the emergency light eye is fastened by means of a sheet metal bracket to the lamp pan or on the frame element.

Die plattenartigen Elemente, die das Abdeckelement 200 bilden, bestehen aus Kunststoff. Daher dehnen sie sich bei Erwärmung entsprechend aus. Das Rahmenelement 400 bzw. die Leuchtenwanne hingegen besteht aus einem Material, üblicherweise aus einem Metall, das sich in seinen Wärmeausdehnungseigenschaften von denjenigen des Abdeckelements 200 unterscheidet. Aus diesem Grund sind die Ausnehmungen gegenüber dem Umfang des Notlichtauges so großzügig bemessen, dass die plattenartigen Elemente bei entsprechender Erwärmung nicht mit dem Notlichtauge 500 kollidieren. In Fig. 5 ist ein Bereich um das Notlichtauge 500 herum bei Ansicht von unten gezeigt. Wie in dieser Skizze erkennbar, ist zwischen dem Notlichtauge 500 und den plattenartigen Elementen ein verhältnismäßig großer Spalt S gebildet, um die genannte Kollisionsgefahr zu vermeiden. Man erkennt in dieser Zeichnung ferner den Blechbügel B, der sich oberhalb des Abdeckelements 200 erstreckt und mit dem das Notlichtauge 500 am Rahmenelement 400 befestigt ist. Der Spalt S beeinträchtigt das äußere Erscheinungsbild der Leuchte. Außerdem kommt es in der Praxis dazu, dass das Notlichtauge 500 nicht - wie in Fig. 5 skizziert - zentrisch innerhalb der Ausnehmungen angeordnet ist und folglich der Spalt S ungleichmäßig erscheint. Hierdurch ist das äußere Erscheinungsbild der Leuchte weiterhin beeinträchtigt.The plate-like elements forming the cover member 200 are made of plastic. Therefore, they expand when heated accordingly. The frame element 400 or the luminaire trough, on the other hand, consists of a material, usually of a metal, which differs in its thermal expansion properties from those of the cover element 200. For this reason, the recesses are dimensioned so generously with respect to the circumference of the emergency light eye that the plate-like elements do not collide with the emergency light eye 500 when heated appropriately. In Fig. 5 is an area around the emergency light eye 500 around when viewed from below. As can be seen in this sketch, a relatively large gap S is formed between the emergency light eye 500 and the plate-like elements, in order to avoid the aforementioned risk of collision. It can be seen in this drawing also the sheet metal bracket B , which extends above the cover 200 and with which the emergency light eye 500 is attached to the frame member 400. The gap S affects the external appearance of the luminaire. In addition, it comes in practice that the emergency light eye 500 not - as in Fig. 5 sketched - is arranged centrally within the recesses and consequently the gap S appears uneven. As a result, the appearance of the lamp is still impaired.

Der Erfindung liegt die Aufgabe zugrunde, eine entsprechende verbesserte Leuchte anzugeben. Insbesondere soll die Leuchte ein verbessertes äußeres Erscheinungsbild ermöglichen.The invention has for its object to provide a corresponding improved luminaire. In particular, the lamp should allow an improved appearance.

Diese Aufgabe wird gemäß der Erfindung mit dem in dem unabhängigen Anspruch genannten Gegenstand gelöst. Besondere Ausführungsarten der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with the object mentioned in the independent claim. Particular embodiments of the invention are indicated in the dependent claims.

Gemäß der Erfindung ist Leuchte vorgesehen, die eine Lichtquelle zur Erzeugung eines Lichts aufweist, sowie ein lichtdurchlässiges Abdeckelement zum Durchtritt des Lichts, wobei das Abdeckelement eine, in einer Ebene liegende Lichtabgabefläche aufweist. Weiterhin weist die Leuchte ein Rahmenelement auf, wobei das Abdeckelement durch das Rahmenelement gehalten angeordnet ist, sowie ein Zusatzelement in Form eines Notlichtelements und/oder eines Sende- bzw. Empfangselements zum Senden und/oder Empfangen elektromagnetischer Strahlung, wobei das Zusatzelement mittels einer Halterung gegenüber dem Rahmenelement gehalten angeordnet ist. Das Abdeckelement weist auf einer, der Lichtabgabefläche gegenüberliegenden Seite eine Aufnahme für das Zusatzelement auf, in die das Zusatzelement zumindest teilweise eingreifend angeordnet ist, wobei die Aufnahme durch eine Ausnehmung oder wenigstens ein Anschlagelement gebildet ist. Die Halterung ist derart gestaltet, dass das Zusatzelement parallel zu der Ebene schwimmend gegenüber dem Rahmenelement gelagert angeordnet ist.According to the invention, luminaire is provided, which has a light source for generating a light, as well as a translucent cover member for the passage of the light, wherein the cover member has a lying in a plane light emitting surface. Furthermore, the lamp has a frame element, wherein the cover is arranged held by the frame member, and an additional element in the form of an emergency light element and / or a transmitting or receiving element for transmitting and / or receiving electromagnetic radiation, wherein the additional element by means of a holder is arranged held the frame member. The cover member has on a, the light emitting surface opposite side of a receptacle for the additional element, in which the additional element is arranged at least partially engaging, wherein the receptacle is formed by a recess or at least one stop element. The holder is designed such that the additional element is arranged parallel to the plane floating against the frame member.

Durch die schwimmende Lagerung des Zusatzelements ist es ermöglicht, die Aufnahme so zu bemessen, dass sie sich besonders nahe bis an das Zusatzelement heran erstreckt. Ein Spalt zwischen der seitlichen Begrenzung der Aufnahme und dem Zusatzelement, wie eingangs beim Stand der Technik beschrieben, lässt sich dadurch so klein gestalten, dass er keine praktisch Beeinträchtigung des äußeren Erscheinungsbildes der Leuchte hervorruft. Außerdem lässt sich der Spalt so klein gestalten, dass das Zusatzelement bei Betrachtung der Lichtabgabefläche stets zentrisch innerhalb der Aufnahme erscheint. Auch hierdurch ist das äußere Erscheinungsbild der Leuchte verbessert.The floating support of the additional element makes it possible to dimension the receptacle so that it extends particularly close to the additional element. A gap between the lateral boundary of the receptacle and the Additional element, as described at the beginning in the prior art, can be made so small that it causes no practical impairment of the appearance of the lamp. In addition, the gap can be made so small that the additional element always appears centric within the recording when viewing the light emitting surface. This also improves the appearance of the luminaire.

Vorzugsweise ist die Halterung weiterhin derart gestaltet, dass das Zusatzelement in einer Richtung normal zu der Ebene nicht schwimmend angeordnet ist. Auf diese Weise lässt sich erzielen, dass das Zusatzelement auch bei einem Kippen oder "auf den Kopf" Drehen der Leuchte nicht aus der Aufnahme heraus fällt.Preferably, the holder is further configured such that the additional element is not floating in a direction normal to the plane. In this way it can be achieved that the additional element does not fall out of the receptacle even when tilted or "turned upside down".

Vorzugsweise umfasst das Sende- bzw. Empfangselement einen Sensor, beispielsweise einen Bewegungssensor oder einen Lichtsensor. Hierfür eignet sich die beschriebene Anordnung besonders gut, weil ein derartiges Sende- bzw. Empfangselement mit einer, einem Notlichtauge bzw. Notlichtelement vergleichbaren Größe und Form gestaltet sein kann.Preferably, the transmitting or receiving element comprises a sensor, for example a motion sensor or a light sensor. For this purpose, the described arrangement is particularly well, because such a transmitting or receiving element can be designed with a, a Notlichtauge or emergency light element comparable size and shape.

Vorzugsweise ist die Halterung fest mit dem Rahmenelement verbunden. Hierdurch ist eine besonders einfache und unmittelbare Halterung des Zusatzelements ermöglicht. Weiterhin vorzugsweise weist die Halterung ein Loch auf sowie ein, das Loch mit einem Spiel durchsetzendes Halteelement, beispielsweise in Form einer Schraube, so dass hierdurch das Zusatzelement schwimmend gelagert ist. Hierdurch ist eine besonders einfache und dabei geeignete schwimmende Lagerung ermöglicht. Bei dem Loch kann es sich vorteilhaft um ein Langloch handeln.Preferably, the holder is firmly connected to the frame member. This allows a particularly simple and immediate support of the additional element. Further preferably, the holder has a hole and a, the hole with a clearance passing through holding element, for example in the form of a screw, so that in this way the additional element is floating. As a result, a particularly simple and thereby suitable floating storage is possible. The hole may advantageously be a slot.

Vorzugsweise weist das Abdeckelement wenigstens zwei plattenartige Elemente auf, die parallel zueinander und dabei insbesondere parallel zu der Ebene angeordnet sind. Dabei ist vorteilhaft die Lichtabgabefläche durch ein erstes der wenigstens zwei plattenartigen Elemente gebildet und ein zweites der wenigstens zwei plattenartigen Elemente bildet zumindest teilweise die Aufnahme. Auf diese Weise lässt sich die Aufnahme besonders einfach und geeignet bilden. Besonders geeignet besteht das Abdeckelement aus Kunststoff.Preferably, the cover member has at least two plate-like elements, which are arranged parallel to each other and in particular parallel to the plane. In this case, the light emission surface is advantageously formed by a first of the at least two plate-like elements and a second of the at least two plate-like elements at least partially forms the receptacle. In this way, the recording can be particularly simple and suitable form. Particularly suitably, the cover consists of plastic.

Vorzugsweise ist das Zusatzelement mit Bezug auf das Abdeckelement und die Ebene außermittig angeordnet. Dies ist vorteilhaft mit Bezug auf das äußere Erscheinungsbild der Leuchte.Preferably, the additional element with respect to the cover and the plane is arranged eccentrically. This is advantageous with respect to the external appearance of the luminaire.

Ebenfalls mit Bezug auf das äußere Erscheinungsbild kann weiterhin vorteilhaft eine Kaschierung des Zusatzelements vorgesehen sein, die auf der Lichtabgabefläche um einen Bereich der, auf die Lichtabgabefläche projizierten Aufnahme herum angeordnet ist. Die Kaschierung umfasst dabei vorzugsweise eine Platte, insbesondere eine Platte aus Aluminium oder Kunststoff. Vorzugsweise ist Kaschierung sich bis zu dem Rahmenelement hin erstreckend gestaltet.Also with respect to the external appearance may further be advantageously provided a lamination of the additional element, which is arranged on the light emitting surface around a portion of, projected onto the light emitting surface around recording. The lamination preferably comprises a plate, in particular a plate made of aluminum or plastic. Preferably, lining is designed to extend up to the frame member.

Fig. 1 zeigt eine perspektivische Schnitt-Skizze eines Bereichs um ein Zusatzelement - hier in Form eines Notlichtelements 5 - einer erfindungsgemäßen Leuchte. Fig. 1 shows a perspective sectional sketch of an area around an additional element - here in the form of an emergency light element 5 - a luminaire according to the invention.

Die Leuchte weist eine (in den Figuren nicht gezeigte) Lichtquelle zur Erzeugung eines Lichts auf. Bei der Lichtquelle kann es sich beispielsweise um Leuchtstoffröhren oder um eine LED-Lichtquelle handeln. Diese Lichtquelle dient zur Erzeugung einer regulären Beleuchtung. Insbesondere kann diese Lichtquelle so gestaltet sein, wie sie aus dem eingangs beschriebenen Stand der Technik an sich bekannt ist.The luminaire has a light source (not shown in the figures) for generating a light. The light source may be, for example, fluorescent tubes or an LED light source. This light source is used to generate a regular lighting. In particular, this light source can be designed as known from the prior art described above.

Weiterhin weist die Leuchte ein lichtdurchlässiges Abdeckelement 2 zum Durchtritt des Lichts auf, wobei das Abdeckelement 2 eine, in einer Ebene E liegende Lichtabgabefläche 3 aufweist. Vorzugsweise ist die Leuchte derart gestaltet, dass diese Ebene E bzw. die Lichtabgabefläche 3 horizontal orientiert ist, wenn die Leuchte wie für einen Betrieb vorgesehen mit Bezug auf die Vertikale ausgerichtet ist. Dementsprechend handelt es sich bei der Leuchte vorzugsweise um eine Deckenleuchte, also beispielsweise um eine Deckenanbau- oder Deckeneinbauleuchte. In der vorliegenden Beschreibung wird von einer solchen Orientierung der Leuchte ausgegangen. Dies ist allerdings nicht beschränkend, die Lichtabgabefläche 3 könnte beispielsweise auch zum Betrieb geneigt gegenüber der Horizontalen vorgesehen sein.Furthermore, the luminaire has a translucent covering element 2 for the passage of the light, the covering element 2 having a light emission surface 3 lying in a plane E. Preferably, the luminaire is designed in such a way that this plane E or the light emission surface 3 is horizontally oriented when the luminaire is aligned with respect to the vertical as intended for operation. Accordingly, the luminaire is preferably a ceiling light, that is, for example, a recessed ceiling or recessed ceiling luminaire. In the present description is based on such an orientation of the lamp. However, this is not restrictive, the light emitting surface 3 could for example also be provided inclined to operate with respect to the horizontal.

Weiterhin weist die Leuchte ein beispielsweise aus einem Metall wie Aluminium bestehendes Rahmenelement 4 auf, wobei das Abdeckelement 2 durch das Rahmenelement 4 gehalten angeordnet ist. Das Rahmenelement 4 kann beispielsweise profilartig gestaltet sein und einen unteren, horizontalen Auflageschenkel 41 aufweisen, auf dem das Abdeckelement 2 aufliegend und beispielsweise auf diese Weise gehalten angeordnet ist. Wie aus Fig. 1 hervorgeht, ist die Leuchte vorzugsweise derart gestaltet, dass das Abdeckelement 2 bei einer temperaturänderungsbedingten Ausdehnung, wie sie insbesondere bei einem Betrieb der Leuchte auftreten kann, nicht gegen das Rahmenelement 4 anschlägt.Furthermore, the lamp has an existing example of a metal such as aluminum frame member 4, wherein the cover 2 is arranged held by the frame member 4. The frame member 4 may for example be designed like a profile and have a lower, horizontal support leg 41, on which the cover 2 is arranged resting and for example held in this way. How out Fig. 1 shows, the lamp is preferably designed such that the cover member 2 does not abut against the frame member 4 in a temperature change-related expansion, as may occur in particular during operation of the lamp.

Weiterhin weist die Leuchte das bereits erwähnte Zusatzelement, hier in Form des Notlichtelements 5 auf. Das Zusatzelement kann anstelle oder zusätzlich zu dem Notlichtelement ein Sende- und/oder Empfangselement zum Senden und/oder Empfangen elektromagnetischer Strahlung aufweisen, beispielsweise in Form eines Bewegungs- bzw. Anwesenheitssensors oder Lichtsensors. In der vorliegenden Beschreibung wird der Einfachheit halber auf ein "Notlichtelement" Bezug genommen, wobei dieses "Notlichtelement" mit Bezug auf seine Halterung allgemeiner als "Zusatzelement" im oben genannten Sinn verstanden werden kann.Furthermore, the light has the already mentioned additional element, here in the form of the emergency light element 5. The additional element may instead of or in addition to the emergency light element, a transmitting and / or receiving element for transmitting and / or Have received electromagnetic radiation, for example in the form of a movement or presence sensor or light sensor. In the present specification, for the sake of simplicity, reference will be made to an "emergency light element", which "emergency light element" with respect to its support may be understood more generally as "supplementary element" in the above-mentioned sense.

Das Notlichtelement 5 ist mittels einer Halterung 6 gegenüber dem Rahmenelement 4 gehalten angeordnet. Das Abdeckelement 2 weist auf einer, der Lichtabgabefläche 3 gegenüber liegenden Seite eine Aufnahme 7 für das Notlichtelement 5 auf, in die das Notlichtelement 5 zumindest teilweise eingreifend angeordnet ist. Die Aufnahme 7 ist beim hier gezeigten Beispiel durch eine Ausnehmung 7 gebildet, sie kann aber alternativ auch beispielsweise durch wenigstens ein (in den Figuren nicht gezeigtes) seitliches Anschlagelement gebildet sein, das den Bewegungsspielraum des Notlichtelements 5 parallel zu der Ebene E begrenzt. Ein derartiges Anschlagelement kann beispielsweise als Teil des Abdeckelements 2 ausgebildet sein, das sich stift- oder rippenförmig von einer Oberseite des Abdeckelements 2 nach oben erstreckt.The emergency light element 5 is held by means of a holder 6 relative to the frame member 4. The cover member 2 has on a, the light emitting surface 3 opposite side of a receptacle 7 for the emergency light element 5, in which the emergency light element 5 is arranged at least partially engaging. The receptacle 7 is formed in the example shown here by a recess 7, but it may alternatively be formed for example by at least one (not shown in the figures) lateral stop element, which limits the range of motion of the emergency light element 5 parallel to the plane E. Such a stop element may for example be formed as part of the cover 2, which extends pin-shaped or rib-shaped from an upper side of the cover 2 upwards.

Die Halterung 6 ist derart gestaltet, dass das Notlichtelement 5 parallel zu der Ebene E schwimmend gegenüber dem Rahmenelement 4 gelagert angeordnet ist. Dies ist insbesondere vorteilhaft für den Fall, dass sich aufgrund einer temperaturänderungsbedingten Ausdehnung des Abdeckelements 2 die Position der Ausnehmung 7 relativ zu dem Rahmenelement 4 verändert. Durch die schwimmende Lagerung des Notlichtelements 5 lässt sich in diesem Fall erzielen, dass das Notlichtelement 5 seine Position gegenüber dem Rahmenelement 4 analog zu der Positionsänderung der Ausnehmung 7 gegenüber dem Rahmenelement 4 ändert, also sozusagen mit der Ausnehmung 7 mitwandert. Daher kann der parallel zu der Ebene E bestehende, kurz der "seitliche" Spielraum zwischen dem Notlichtelement 5 und den entsprechenden Begrenzungen der Ausnehmung 7 besonders klein bemessen sein. Auf diese Weise lässt sich - im Vergleich zum eingangs erwähnten Stand der Technik - vermeiden, dass ein unschöner Spalt zwischen dem Notlichtelement 5 und den Begrenzungen der Ausnehmung 7 zu sehen ist, wenn man auf die Lichtabgabefläche 3 der Leuchte blickt. Der Spielraum kann auf diese Weise so klein gestaltet werden, dass praktisch kein entsprechender Spalt erkennbar ist.The holder 6 is designed such that the emergency light element 5 is arranged to float parallel to the plane E with respect to the frame element 4. This is particularly advantageous in the event that the position of the recess 7 changes relative to the frame element 4 due to a temperature change-related expansion of the cover 2. Due to the floating mounting of the emergency light element 5, it is possible in this case for the emergency light element 5 to change its position relative to the frame element 4 analogously to the change in position of the recess 7 relative to the frame element 4, that is to say to move with the recess 7. Therefore, the parallel to the plane E existing, in short the "lateral" clearance between the emergency light element 5 and the corresponding boundaries of the recess 7 may be particularly small. In this way - in comparison to the prior art mentioned above - avoid that an ugly gap between the emergency light element 5 and the boundaries of the recess 7 can be seen when looking at the light emitting surface 3 of the lamp. The scope can be made so small in this way that virtually no corresponding gap is visible.

Beim gezeigten Beispiel weist das Notlichtelement 5 als Lichtquelle eine LED-Lichtquelle 51 auf. Vorzugsweise weist das Notlichtelement 5 weiterhin ein optisches Element 53 zur Beeinflussung eines von der LED-Lichtquelle 51 erzeugten Lichts auf.In the example shown, the emergency light element 5 as a light source on an LED light source 51. Preferably, the emergency light element 5 further comprises an optical element 53 for influencing a light generated by the LED light source 51.

Die seitliche Begrenzung des Notlichtelements 5 ist durch ein Umfassungselement 52 des Notlichtelements 5 gebildet. Das Umfassungselement 52 kann beispielsweise, parallel zu der Ebene E einen kreisrunden Querschnitt aufweisen, wobei die Ausnehmung 7 ebenfalls einen kreisrunden Querschnitt aufweist, der entsprechend korrespondierend bemessen ist, so dass hierdurch die genannte Spaltminimierung erzielt ist. Selbstverständlich können jedoch auch andere Umfangsformen des Notlichtelements 5 und der Ausnehmung 7 vorgesehen sein, beispielsweise rechteckig.The lateral boundary of the emergency light element 5 is formed by a surrounding element 52 of the emergency light element 5. The enclosing element 52 may, for example, have a circular cross-section parallel to the plane E, wherein the recess 7 likewise has a circular cross-section which is dimensioned correspondingly, so that thereby the mentioned gap minimization is achieved. Of course, however, other peripheral shapes of the emergency light element 5 and the recess 7 may be provided, for example rectangular.

Vorzugsweise ist die Halterung 6 derart gestaltet, dass das Notlichtelement 5 in einer Richtung normal zu der Ebene E nicht schwimmend angeordnet ist. Auf diese Weise lässt sich vermeiden, dass das Notlichtelement 5 bei einem Kippen der Leuchte, beispielswiese im Rahmen eines Transports der Leuchte, aus der Ausnehmung 7 heraus fällt.Preferably, the holder 6 is designed such that the emergency light element 5 is not arranged to float in a direction normal to the plane E. In this way, it is possible to prevent the emergency light element 5 from falling out of the recess 7 during a tilting of the luminaire, for example during a transport of the luminaire.

Beim gezeigten Beispiel ist die Halterung 6 fest mit dem Rahmenelement 4 verbunden. Alternativ kann die Halterung 6 auch mit einem anderen Bauteil der Leuchte, beispielsweise einer Leuchtenwanne verbunden sein. Grundsätzlich ist auch eine entsprechende Verbindung der Halterung 6 mit dem Abdeckelement 2 möglich.In the example shown, the holder 6 is fixedly connected to the frame member 4. Alternatively, the holder 6 can also be connected to another component of the luminaire, for example a luminaire tub. In principle, a corresponding connection of the holder 6 with the cover 2 is possible.

Vorzugsweise weist die Halterung 6 einen ersten Teil 61 auf, der fest mit dem Rahmenelement 4 verbunden ist, sowie einen zweiten Teil 62, der fest mit dem Notlichtelement 5 verbunden ist, wobei die schwimmende Lagerung zwischen diesen beiden Teilen 61, 62 gebildet ist. Bei dem in Fig. 1 gezeigten Beispiel weist der erste Teil 61 der Halterung 6 ein Loch 8 auf und der zweite Teil 62 ein, das Loch 8 mit einem Spiel durchsetzendes Halteelement 9, beispielswiese in Form einer Schraube; durch entsprechend größere Bemessung des Lochs 8 im Vergleich zum seitlichen Umfang des Halteelements 9 auf Höhe des Lochs 8 lässt sich die schwimmende Lagerung des Notlichtelements 5 besonders geeignet erzielen. Ebenso kann selbstverständlich das Loch 8 an dem zweiten Teil 62 der Halterung 6 ausgebildet sein und das Halteelement 9 an dem ersten Teil der Halterung 6.Preferably, the holder 6 has a first part 61 which is fixedly connected to the frame member 4, and a second part 62 which is fixedly connected to the emergency light element 5, wherein the floating bearing between these two parts 61, 62 is formed. At the in Fig. 1 As shown, the first part 61 of the holder 6 has a hole 8 and the second part 62 a, the hole 8 with a clearance passing through holding element 9, for example in the form of a screw; by correspondingly larger dimensioning of the hole 8 in comparison to the lateral circumference of the retaining element 9 at the level of the hole 8, the floating mounting of the emergency light element 5 can be achieved particularly suitable. Likewise Of course, the hole 8 may be formed on the second part 62 of the holder 6, and the holding element 9 on the first part of the holder 6.

In Fig. 2 ist eine Explosionsdarstellung des Notlichtelements 5 und der Halterung 6 gemäß einer Variante skizziert, wobei die Bezugszeichen analog gebraucht sind. Hier ist das Loch 8 wiederum an dem ersten Teil 61 der Halterung 8 ausgebildet und das Halteelement 9 bzw. die Schraube an dem zweiten Teil 62. Fig. 3 zeigt die in Fig. 2 gezeigte Anordnung in entsprechend zusammengesetztem Zustand.In Fig. 2 an exploded view of the emergency light element 5 and the holder 6 is sketched according to a variant, wherein the reference numerals are used analogously. Here again, the hole 8 is formed on the first part 61 of the holder 8 and the holding element 9 or the screw on the second part 62. Fig. 3 shows the in Fig. 2 shown arrangement in accordance assembled state.

Wie aus Fig. 2 beispielhaft hervorgeht, ist das Loch 9 vorteilhaft ein Langloch. Das Langloch ist dabei vorzugsweise so gestaltet, dass sich seine Hauptachse parallel zu der Richtung der zu erwartenden temperaturbedingten Bewegung der Ausnehmung 7 erstreckt.How out Fig. 2 By way of example, the hole 9 is advantageously a slot. The slot is preferably designed so that its main axis extends parallel to the direction of the expected temperature-induced movement of the recess 7.

Das Loch 8 kann vorteilhaft durch einen zumindest im Wesentlichen horizontal bzw. parallel zu der Ebene E ausgerichteten plattenförmigen Bereich der Halterung 6, insbesondere in einem entsprechenden Schenkel der Halterung 6 gebildet sein; hierdurch lässt sich besonders geeignet erzielen, dass das Notlichtelement 5 in einer Richtung normal zu der Ebene E nicht schwimmend gelagert angeordnet ist.The hole 8 can advantageously be formed by a plate-shaped region of the holder 6 aligned at least substantially horizontally or parallel to the plane E, in particular in a corresponding leg of the holder 6; This makes it possible to achieve particularly suitable that the emergency light element 5 is arranged not floating in a direction normal to the plane E.

Beim gezeigten Beispiel weist das Abdeckelement 2 wenigstens zwei plattenartige Elemente 21, 22 auf, die parallel zueinander und dabei insbesondere zumindest in erster Näherung parallel zu der Ebene E angeordnet sind. Die Lichtabgabefläche 3 ist dabei durch ein erstes plattenartiges Element 21 dieser wenigstens zwei plattenartigen Elemente 21, 22 gebildet. Ein zweites plattenartiges Element 22 dieser wenigstens zwei plattenartigen Elemente 21, 22 bildet zumindest teilweise die Ausnehmung 7, insbesondere durch eine Durchgangsöffnung. Das erste plattenartige Element 21 ist vorzugsweise ein glasklares Element; die Lichtabgabefläche 3 ist vorzugsweise plan. Bei dem zweiten plattenartigen Element 22 kann es sich beispielsweise um eine Prismenscheibe oder eine Streuscheibe oder dergleichen handeln. Selbstverständlich können insgesamt auch drei oder noch mehr entsprechende plattenartige Elemente zur Bildung des Abdeckelements 2 vorgesehen sein, wobei ein oberer Teil dieser Elemente die Ausnehmung 7 bildet, insbesondere durch entsprechend korrespondierende Durchgangsöffnungen.In the example shown, the cover element 2 has at least two plate-like elements 21, 22 which are arranged parallel to one another and in particular at least to a first approximation parallel to the plane E. The light emission surface 3 is formed by a first plate-like element 21 of these at least two plate-like elements 21, 22. A second plate-like element 22 of these at least two plate-like elements 21, 22 at least partially forms the recess 7, in particular through a passage opening. The first plate-like member 21 is preferably a crystal clear element; the light-emitting surface 3 is preferably flat. The second plate-like element 22 may, for example, be a prismatic disk or a diffuser or the like. Of course, a total of three or even more corresponding plate-like elements may be provided to form the cover 2, wherein an upper part of these elements the recess 7 forms, in particular by correspondingly corresponding passage openings.

Das Notlichtauge 5 ist vorzugsweise von oben in die Ausnehmung 7 eingelegt angeordnet.The emergency light eye 5 is preferably arranged from above into the recess 7.

Vorzugsweise besteht das Abdeckelement 2 aus Kunststoff, bzw. bestehen die wenigstens zwei plattenartigen Elemente 21, 22 aus Kunststoff.Preferably, the cover 2 is made of plastic, or consist of at least two plate-like elements 21, 22 made of plastic.

Das Notlichtelement 5 kann vorteilhaft mit Bezug auf das äußere Erscheinungsbild der Leuchte - wie an sich aus dem Stand der Technik bekannt und beispielswiese in Fig. 6 dargestellt - mit Bezug auf das Abdeckelement 2 und die Ebene E außermittig angeordnet sein.The emergency light element 5 can be advantageous with respect to the external appearance of the lamp - as known from the prior art and example meadow in Fig. 6 shown - be arranged off-center with respect to the cover 2 and the plane E.

Wie weiterhin in Fig. 4 beispielhaft gezeigt, kann die Leuchte außerdem eine Kaschierung 10 des Zusatzelements 5 aufweisen, die auf der Lichtabgabefläche 3 um einen Bereich der, auf die Lichtabgabefläche 3 projizierten Ausnehmung 7 bzw. Aufnahme herum angeordnet ist. Vorteilhaft umfasst die Kaschierung 10 eine Platte, insbesondere eine Platte aus Aluminium oder Kunststoff. Wie in Fig. 4 beispielhaft gezeigt, ist dabei die Kaschierung so gestaltet, dass sie sich bis zu dem Rahmenelement 4 hin erstreckt.As continues in Fig. 4 By way of example, the luminaire may also have a lamination 10 of the additional element 5, which is arranged on the light-emitting surface 3 around a region of the recess 7 or receptacle projected onto the light-emitting surface 3. Advantageously, the lamination 10 comprises a plate, in particular a plate made of aluminum or plastic. As in Fig. 4 by way of example, the lamination is designed such that it extends as far as the frame element 4.

Durch die Kaschierung 10 lässt sich auch ein minimaler Freiraum zwischen dem Notlichtelement 5 und der seitlichen Begrenzung der Ausnehmung 7 überdecken. Die Kaschierung 10 kann dabei fest mit der Lichtabgabefläche 3 verbunden sein, so dass auch sie temperaturschwankungsbedingte Lageänderungen des Notlichtelements 5 bzw. der Ausnehmung 7 entsprechend mit vollzieht.The lamination 10 also allows a minimal clearance between the emergency light element 5 and the lateral boundary of the recess 7 to be covered. The lamination 10 may be firmly connected to the light emitting surface 3, so that they also takes place in accordance with temperature fluctuation changes in position of the emergency light element 5 and the recess 7 accordingly.
