Description

Die Erfindung betrifft eine Leuchte mit einem Rahmenelement.The invention relates to a luminaire with a frame element.

Es sind Rettungszeichenleuchten bekannt, bei denen die transparenten, mit den Piktogrammen versehenen Scheiben von einem umlaufenden Aluminiumrahmen umgeben sind. Zur Herstellung eines solchen Rahmens werden vier, jeweils an ihren Endbereichen entsprechend auf Gehrung geschnittene Einzelteile verwendet. Diese Einzelteile werden dann in einem Verfahrensschritt an ihren Endbereichen mithilfe von Eckverbindern zusammengefügt, beispielsweise durch Pressen.Escape sign luminaires are known in which the transparent, provided with the pictograms discs are surrounded by a surrounding aluminum frame. For the production of such a frame, four individual parts are used, which are each mitred at their end regions. These individual parts are then assembled in one step at their end using corner connectors, for example by pressing.

Die Herstellung dieses Rahmens ist vergleichsweise aufwändig und zeitintensiv. Außerdem hat sich in der Praxis gezeigt, dass es immer wieder zu Problemen bei der Montage der Eckverbinder kommt.The preparation of this framework is relatively complex and time consuming. In addition, it has been shown in practice that there are always problems with the assembly of the corner connectors.

Aus der GB 1 558 844 A ist ein Lichtkasten mit einem Rahmen bekannt, der aus einem einstückigen Teil durch Biegungen gebildet ist. Der Rahmen umgibt eine plattenförmige Anzeigetafel.From the GB 1 558 844 A For example, a light box is known with a frame formed from a one-piece piece by bends. The frame surrounds a plate-shaped display panel.

Der Erfindung liegt die Aufgabe zugrunde, eine entsprechende verbesserte Leuchte mit einem Rahmenelement anzugeben; insbesondere soll eine erleichterte Herstellung ermöglicht sein.The invention has for its object to provide a corresponding improved luminaire with a frame element; in particular, a facilitated production should be made possible.

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

Gemäß der Erfindung ist eine Leuchte mit einem Rahmenelement vorgesehen, wobei das Rahmenelement derart gestaltet, dass es sich aus einem Linear-Zustand, in dem es sich längs einer Längsachse erstreckt, durch Biegen der Sollbiegestellen in einen Rahmen-Zustand biegen lässt, in dem es als Rahmen der Leuchte dienen kann.According to the invention, a lamp is provided with a frame member, wherein the frame member designed such that it is a linear state in which it extends along a longitudinal axis, can bend by bending the predetermined bending points in a frame state in which it can serve as a frame of the lamp.

Durch diese Ausgestaltung lässt sich vermeiden, dass zur Rahmenbildung vier Einzelteile miteinander verbunden werden müssen. Insbesondere sind keine Eckverbinder erforderlich. Die Sollbiegestellen ermöglichen ein einfaches Biegen bzw. Falten zur Herstellung des Rahmens, so dass eine besonders einfache und schnelle Herstellung des Rahmens ermöglicht ist.By this configuration can be avoided that four individual parts must be connected to each other for framing. In particular, no corner connectors are required. The predetermined bending points allow easy bending or folding for the production of the frame, so that a particularly simple and fast production of the frame is made possible.

Erfindungsgemäß weist das Rahmenelement Rastelemente zur Fixierung des Rahmenelements im Rahmen-Zustand auf. Durch solche Rastelemente ist eine besonders einfache Montage des Rahmenelements ermöglicht.According to the invention, the frame element has latching elements for fixing the frame element in the frame state. By such locking elements a particularly simple assembly of the frame element is made possible.

Erfindungsgemäß weist die Leuchte weiterhin ein in erster Näherung plattenförmiges Lichtabgabeelement auf, wobei das Rahmenelement im Rahmen-Zustand rahmenförmig um das Lichtabgabeelement herum angeordnet ist.According to the invention, the lamp further comprises a plate-shaped light-emitting element in a first approximation, wherein the frame element is arranged frame-shaped around the light-emitting element in the frame state.

Erfindungsgemäß weist dabei das Lichtabgabeelement Rastelemente auf, die für eine rastende Verbindung mit den Rastelementen des Rahmenelements zur Fixierung des Rahmenelements im Rahmen-Zustand an dem Lichtabgabeelement ausgebildet sind. Dies ermöglicht eine besonders einfache Montage des Rahmenelements an dem Lichtabgabeelement.According to the invention, the light-emitting element has latching elements which are designed for a latching connection with the latching elements of the frame element for fixing the frame element in the frame state to the light-emitting element. This allows a particularly simple mounting of the frame element to the light-emitting element.

Die rastende Verbindung ist dabei vorzugsweise derart ausgestaltet, dass das Rahmenelement sowohl gegen ein Aufklappen gesichert ist, als auch gegen ein Auseinanderbewegen der beiden Endbereiche des Rahmenelements. Hierdurch ist eine besonders stabile Fixierung des Rahmenelements an dem Lichtabgabeelement ermöglicht.The latching connection is preferably designed such that the frame element is secured both against unfolding, as well as against a movement apart of the two end portions of the frame member. This allows a particularly stable fixation of the frame element to the light-emitting element.

Vorzugsweise ist die rastende Verbindung derart ausgestaltet, dass das Rahmenelement im Rahmen-Zustand unter Zug gehalten ist.Preferably, the latching connection is designed such that the frame element is held under train in the frame state.

Das Lichtabgabeelement besteht vorzugsweise aus Kunststoff, insbesondere aus zwei Kunststoffschalen.The light-emitting element is preferably made of plastic, in particular of two plastic shells.

Bei der Leuchte handelt es sich vorzugsweise um eine Rettungszeichenleuchte.The luminaire is preferably a rescue sign luminaire.

Vorzugsweise besteht das Rahmenelement aus Aluminium. Hierdurch lässt sich das Rahmenelement so gestalten, dass es besonders einfach gebogen werden kann und dennoch ausreichende Stabilität aufweist.The frame element is preferably made of aluminum. As a result, the frame element can be designed so that it can be bent particularly easily and yet has sufficient stability.

Vorzugsweise weist das Rahmenelement genau vier Sollbiegestellen auf. Hierdurch lässt sich ein viereckiger Rahmen bilden, bei dem die zwischen den beiden Endbereichen des Rahmens gebildete Stoßstelle nicht an einer Ecke ausgebildet ist.Preferably, the frame member has exactly four predetermined bending points. This makes it possible to form a quadrangular frame in which the joint formed between the two end regions of the frame is not formed at a corner.

Vorzugsweise sind an den Sollbiegestellen Gehrungsschnitte ausgebildet. Dies ermöglicht eine besonders ebenmäßige Ausbildung der Ecken des Rahmens.Miter cuts are preferably formed at the predetermined bending points. This allows a particularly even formation of the corners of the frame.

Vorzugsweise weisen die Sollbiegestellen Materialverdünnungen auf, die quer zu der Längsachse ausgebildet sind. Hierdurch lassen sich besonders gut handhabbare Sollbiegestellen ausbilden.Preferably, the predetermined bending points on material dilutions, which are formed transversely to the longitudinal axis. As a result, can be trained particularly well-handled predetermined bending points.

Vorzugsweise ist das Rahmenelement aus einem U-förmigen Profilteil hergestellt, insbesondere aus einem Strangpressprofilteil. Hierdurch ist weiterhin eine besonders einfache Herstellung des Rahmenelements und damit des Rahmens ermöglicht.Preferably, the frame member is made of a U-shaped profile part, in particular of an extruded profile part. As a result, a particularly simple production of the frame member and thus of the frame is further enabled.

Vorzugsweise sind die Rastelemente an den beiden, durch die U-Form des Profilteils gebildeten U-Schenkeln ausgebildet, insbesondere an deren, mit Bezug auf die U-Form nach innen weisenden Seiten. Hierdurch ist eine verdeckte Anordnung der Rastelemente im Rahmen-Zustand ermöglicht, so dass ein weiterhin besonders ebenmäßiges äußeres Erscheinungsbild des durch das Rahmenelement gebildeten Rahmens erzielt ist.Preferably, the latching elements are formed on the two, formed by the U-shape of the profile part U-legs, in particular at their, with respect to the U-shape inwardly facing sides. This allows a concealed arrangement of the locking elements in the frame state, so that a further particularly even external appearance of the frame formed by the frame element is achieved.

Hierdurch lässt sich ein quasi ringförmig geschlossener Rahmen bilden. Vorzugsweise ist im Rahmen-Zustand der Abstand zwischen dem ersten Endbereich 21 und dem zweiten Endbereich 22 kleiner als 2 mm, besonders bevorzugt kleiner als 1 mm.How out Fig. 1 shows, the design is preferably such that in the frame state between the first end portion 21 and the second end portion 22 a joint 7 is formed. This makes it possible to form a quasi-annular closed frame. In the frame state, the distance between the first end region 21 and the second end region 22 is preferably less than 2 mm, particularly preferably less than 1 mm.

Fig. 4 zeigt eine entsprechende Aufsicht auf das Rahmenelement 2 und Fig. 2 zeigt eine perspektivische Skizze um den zweiten Endbereich 22 des Rahmenelements 2 im Linear-Zustand. Fig. 4 shows a corresponding top view of the frame member 2 and Fig. 2 shows a perspective sketch around the second end portion 22 of the frame member 2 in the linear state.

Das Rahmenelement 2 weist Faltstellen bzw. Sollbiegestellen 3 auf und ist dabei derart gestaltet, dass es sich aus dem Linear-Zustand heraus durch Biegen der Sollbiegestellen 3 in den Rahmen-Zustand verformen bzw. biegen lässt. Auf diese Weise lässt sich für die Leuchte 10 ein Rahmen bilden, ohne dass hierfür Eckverbinder erforderlich wären.The frame element 2 has folding points or predetermined bending points 3 and is designed such that it can be deformed or bent from the linear state by bending the predetermined bending points 3 into the frame state. In this way, a frame can be formed for the luminaire 10 without the need for corner connectors.

Vorzugsweise besteht das Rahmenelement 2 aus Aluminium. Herstellungstechnisch vorteilhaft ist es aus einem U-förmigen Profilteil gebildet, insbesondere aus einem Strangpressprofilteil. In Fig. 5 ist ein entsprechender Querschnitt normal zu der Längsachse L skizziert, der die U-Form des Profilteils erkennen lässt. Durch die U-Form sind zwei U-Schenkel 24, 25 und ein, die beiden U-Schenkel 24, 25 miteinander verbindender Verbindungsschenkel 26 gebildet.Preferably, the frame member 2 is made of aluminum. In terms of manufacturing technology, it is formed from a U-shaped profile part, in particular from an extruded profile part. In Fig. 5 is a corresponding cross-section normal to the longitudinal axis L sketched, which reveals the U-shape of the profile part. Due to the U-shape, two U-legs 24, 25 and one, the two U-legs 24, 25 interconnecting connecting leg 26 are formed.

Wie beim Ausführungsbeispiel der Fall, weist das Rahmenelement 2 vorzugsweise insgesamt genau vier Sollbiegestellen 31, 32, 33, 34 auf. Die Stoßstelle 7 lässt sich auf diese Weise im Fall eines viereckigen Rahmens zwischen zwei benachbarten Ecken ausbilden.As in the exemplary embodiment of the case, the frame element 2 preferably has a total of exactly four predetermined bending points 31, 32, 33, 34. The joint 7 can be formed in this way in the case of a square frame between two adjacent corners.

Vorzugsweise sind im Rahmen-Zustand durch das Rahmenelement 2 jeweils zwischen zwei benachbarten Sollbiegestellen 3 insbesondere lediglich geradlinig verlaufende Abschnitte s1, s2, s3 gebildet und zwischen den beiden Sollbiegestellen 31, 34, die im Linear-Zustand die beiden äußeren der Sollbiegestellen 3 bilden, ein weiterer, ebenfalls insbesondere lediglich geradlinig verlaufender, Abschnitt s4. Im Linear-Zustand sind alle diese Abschnitte s1, s2, s3, s4 längs der Längsachse L orientiert.Preferably in the frame state by the frame member 2 between two adjacent predetermined bending points 3 in particular only rectilinear portions s1, s2, s3 are formed and between the two predetermined bending points 31, 34 which form the two outer of the predetermined bending points 3 in the linear state Another, also in particular only rectilinearly extending, section s4 . In the linear state, all these sections s1, s2, s3, s4 are oriented along the longitudinal axis L.

Im gezeigten Fall, in dem das Rahmenelement 2 im Rahmen-Zustand einen viereckigen Rahmen bildet, sind auf diese Weise vier geradlinig verlaufende Abschnitte gebildet, durch die die Seiten des entsprechenden Vierecks gebildet sind. Die Stoßstelle 7 ist dabei innerhalb des weiteren Abschnitts s4 gebildet.In the case shown, in which the frame element 2 forms a quadrangular frame in the frame state, four rectilinear sections are formed in this way, through which the sides of the corresponding quadrangle are formed. The joint 7 is formed within the further section s4 .

Um ein besonders ebenmäßiges äußeres Erscheinungsbild des Rahmens zu ermöglichen, sind vorteilhaft an den Sollbiegestellen 3 Gehrungsschnitte 4 ausgebildet. Wie im gezeigten Beispiel der Fall, sind bei einem viereckigen Rahmen die Gehrungsschnitte 4 gegenüber der Längsachse L vorteilhaft um 45° geneigt ausgebildet. Insbesondere sind durch die Gehrungsschnitte 4 an den Sollbiegestellen 3 jeweils keilförmige Ausnehmungen gebildet, die einen Winkel von 90° bilden. Wie aus Fig. 2 hervorgeht, können vorzugsweise die Gehrungsschnitte 4 derart gestaltet sein, dass sie sich bis in den Verbindungsschenkel 26 hinein erstrecken.In order to enable a particularly even external appearance of the frame, 3 miter cuts 4 are advantageously formed at the predetermined bending points. As in the example shown, in the case of a quadrangular frame, the miter cuts 4 are advantageously inclined by 45 ° with respect to the longitudinal axis L. In particular, wedge-shaped recesses are formed by the miter cuts 4 at the predetermined bending points 3, which form an angle of 90 °. How out Fig. 2 As can be seen, preferably the miter cuts 4 can be designed such that they extend into the connecting leg 26 into it.

Um ein einfaches Biegen zu ermöglichen, weisen die Sollbiegestellen 3 jeweils Materialverdünnungen 5 auf, die quer, insbesondere rechtwinklig zu der Längsachse L ausgebildet sind. Vorzugsweise sind die Materialverdünnungen 5 derart gestaltet, dass das Rahmenelement 2 hierdurch jeweils an den Sollbiegestellen 3 eine reduzierte Stärke aufweist, die etwa zwischen 0,01% und 0,2% der Länge l des Rahmenelements 2 im Linear-Zustand längs der Längsachse L beträgt. Vorzugswise sind die Materialverdünnungen 5 durch die Gehrungsschnitte 4 ausgebildet.In order to allow a simple bending, the predetermined bending points 3 each have material dilutions 5, which are formed transversely, in particular at right angles to the longitudinal axis L. The material dilutions 5 are preferably designed in such a way that the frame element 2 hereby has a reduced thickness at the predetermined bending points 3, which is approximately between 0.01% and 0.2% of the length l of the frame element 2 in the linear state along the longitudinal axis L. , Vorzugswise the material dilutions 5 are formed by the miter cuts 4.

Beispielsweise kann die Länge l zwischen 500 mm und 1500 mm betragen und die Stärke an den Sollbiegestellen 3 zwischen 0,4 mm und 1,0 mm, vorzugsweise zwischen 0,5 mm und 0,9 mm, beispielswiese 0,7 mm.For example, the length l may be between 500 mm and 1500 mm and the thickness at the predetermined bending points 3 between 0.4 mm and 1.0 mm, preferably between 0.5 mm and 0.9 mm, for example 0.7 mm.

Der Abstand zwischen den beiden Endbereichen 21, 22 im Rahmen-Zustand beträgt vorzugsweise weniger als 0,1% der Länge /. The distance between the two end regions 21, 22 in the frame state is preferably less than 0.1% of the length / .

Das Rahmenelement 2 kann eine - in Fig. 5 bezeichnete - Breite b parallel zu den Sollbiegestellen 3 und eine Höhe h rechtwinklig zu der Längsachse L und der Breite b aufweisen, wobei die Breite b vorzugsweise zwischen 1% und 3% der Länge l beträgt und die Höhe h vorzugsweise zwischen 0,2% und 1,0% der Länge /. Die Breite b kann zwischen 5 mm und 50 mm, vorzugsweise zwischen 10 mm und 25 mm betragen, die Höhe h zwischen 2 mm und 10 mm, vorzugsweise zwischen 3 mm und 8 mm.The frame element 2 may have a - in Fig. 5 designated - width b parallel to the predetermined bending points 3 and a height h perpendicular to the longitudinal axis L and the width b Preferably, wherein the width b is preferably between 1% and 3% of the length l and the height h is preferably between 0.2% and 1.0% of the length / . The width b may be between 5 mm and 50 mm, preferably between 10 mm and 25 mm, the height h between 2 mm and 10 mm, preferably between 3 mm and 8 mm.

Die Gehrungsschnitte 4 und/oder die Materialverdünnungen 5 können insbesondere durch Fräsen gebildet sein.The miter cuts 4 and / or the material dilutions 5 can be formed in particular by milling.

Zur Fixierung des Rahmenelements 2 im Rahmen-Zustand weist das Rahmenelement 2 weiterhin vorzugsweise Rastelemente 6 auf.For fixing the frame element 2 in the frame state, the frame element 2 further preferably has latching elements 6.

Wie in Fig. 6 beispielhaft skizziert, weist die Leuchte 10 vorzugsweise ein in erster Näherung plattenförmiges Lichtabgabeelement 11 auf, wobei das Rahmenelement 2 im Rahmen-Zustand rahmenförmig um das Lichtabgabeelement 11 herum angeordnet ist.As in Fig. 6 sketched by way of example, the lamp 10 preferably has a plate-shaped light-emitting element 11 in a first approximation, the frame element 2 being arranged in the frame state around the light-emitting element 11 in the form of a frame.

Fig. 9 zeigt eine entsprechende Frontansicht. Fig. 9 shows a corresponding front view.

Das Lichtabgabeelement 11 kann ein Piktogramm oder mehrere Piktogramme, insbesondere auf zwei gegenüberliegenden, voneinander durch das Rahmenelement 2 getrennte, Außenflächen aufweisen. Vorzugsweise besteht das Lichtabgabeelement 11 aus Kunststoff; beispielsweise ist es aus zwei Kunststoffschalen 111, 112 gebildet. Dabei ist die Gestaltung vorzugsweise derart, dass die zwischen den Kunststoffschalen 111, 112 gebildete Trennfuge durch das Rahmenelement 2 abgedeckt ist, wenn das Rahmenelement 2 wie vorgesehen im Rahmen-Zustand um das Lichtabgabeelement 11 herum angeordnet ist.The light-emitting element 11 can have one or more pictograms, in particular on two opposite outer surfaces separated from one another by the frame element 2. Preferably, the light-emitting element 11 is made of plastic; For example, it is formed from two plastic shells 111, 112. In this case, the design is preferably such that the parting line formed between the plastic shells 111, 112 is covered by the frame member 2, when the frame member 2 is arranged around the light emitting element 11 as intended in the frame state.

Um eine besonders einfach herzustellende und dabei stabile und zuverlässige Fixierung des Rahmenelements 2 an dem Lichtabgabeelement 11 zu ermöglichen, weist das Lichtabgabeelement 11 Rastelemente 9 auf, die für eine rastende Verbindung mit den Rastelementen 6 des Rahmenelements 2 zur Fixierung des Rahmenelements 2 im Rahmen-Zustand ausgebildet sind.In order to enable a particularly easy to manufacture while stable and reliable fixation of the frame member 2 to the light emitting element 11, the light emitting element 11 has latching elements 9, for a latching connection with the locking elements 6 of the frame member 2 for fixing the frame member 2 in the frame state are formed.

Diese rastende Verbindung ist vorzugsweise derart ausgestaltet, dass das Rahmenelement 2 sowohl gegen ein Aufklappen aus dem Rahmen-Zustand gesichert ist, als auch gegen ein Auseinanderbewegen der beiden Endbereiche 21, 22 des Rahmenelements 2. Insbesondere kann die rastende Verbindung derart ausgestaltet sein, dass das Rahmenelement 2 im Rahmen-Zustand unter Zug gehalten ist.This latching connection is preferably designed such that the frame element 2 is secured both against unfolding from the frame state In particular, the latching connection can be configured such that the frame member 2 is held under train in the frame state.

Beim gezeigten Ausfuhrungsbeispiel umfassen hierzu die Rastelemente 9 des Lichtabgabeelements 11 ein - in Fig. 7 beispielhaft gezeigtes - insbesondere elastisch ausbiegbares Schnappelement 91, das mit einer durch die Rastelemente 6 des Rahmenelements 2 gebildeten Rastnase 61 wechselwirkt, so dass das Rahmenelement 2 gegen ein Lösen von dem Lichtabgabeelement 11, also gegen ein Aufklappen aus dem Rahmen-Zustand gesichert ist.In the exemplary embodiment shown, this includes the locking elements 9 of the light emitting element 11 a - Fig. 7 exemplified - in particular elastically ausbiegbares snap element 91, which interacts with a latching lug 61 formed by the locking elements 6 of the frame member 2, so that the frame member 2 is secured against loosening of the light emitting element 11, ie against unfolding from the frame state.

Insbesondere kann - wie beispielhaft aus Fig. 8 ersichtlich - an jedem der beiden Endbereiche 21, 22 des Rahmenelements 2 jeweils wenigstens eine derartige Rastnase 61, 61' ausgebildet sein und die Rastelemente 9 des Lichtabgabeelements 11 können dementsprechend - wie beispielhaft aus Fig. 7 ersichtlich - wenigstens zwei Schnappelemente 91, 91' aufweisen, so das jeweils eine der Rastnasen 61, 61' mit jeweils einem der Schnappelemente 91, 91' zur Herstellung der rastenden Verbindung wechselwirkt. Im gezeigten Beispiel sind - wie beispielhaft aus Fig. 4 ersichtlich - an jedem der beiden Endbereiche 21, 22 des Rahmenelements 2 jeweils zwei derartige Rastnasen 61, 61' ausgebildet und dementsprechend weisen - wie beispielhaft aus Fig. 7 ersichtlich - die Rastelemente 9 des Lichtabgabeelements 11 vier entsprechende Schnappelemente 91, 91' auf.In particular - as exemplified Fig. 8 can be formed - at each of the two end portions 21, 22 of the frame member 2 each at least one such latching lug 61, 61 'and the locking elements 9 of the light emitting element 11 can accordingly - as exemplified Fig. 7 seen - at least two snap elements 91, 91 ', so that in each case one of the latching lugs 61, 61' interacts with one of the snap elements 91, 91 'for producing the latching connection. In the example shown are - as exemplified Fig. 4 seen - at each of the two end portions 21, 22 of the frame member 2 each have two such locking lugs 61, 61 'is formed and accordingly have - as exemplified Fig. 7 seen - the locking elements 9 of the light emitting element 11 four corresponding snap elements 91, 91 'on.

Weiterhin umfassen beim Ausführungsbeispiel die Rastelemente 9 des Lichtabgabeelements 11 eine Spannnoppe 92, die mit einer durch die Rastelemente 6 des Rahmenelements 2 gebildeten - in Fig. 8 beispielhaft gezeigten - Ausnehmung 62 zur Herstellung der rastenden Verbindung wechselwirkt, so dass das Rahmenelement 2 gegen ein Auseinanderbewegen der beiden Endbereiche 21, 22, also gegen ein Öffnen der Stoßstelle 7 gesichert ist. Im verrasteten Zustand greift hierzu die Spannnoppe 92 in die Ausnehmung 62 ein.Furthermore, in the exemplary embodiment, the locking elements 9 of the light-emitting element 11 comprise a clamping nub 92, which with a formed by the locking elements 6 of the frame element 2 - Fig. 8 as shown by way of example - recess 62 interacts to produce the latching connection, so that the frame element 2 is secured against moving apart of the two end regions 21, 22, ie against opening of the joint 7. In the locked state, the clamping knob 92 engages in the recess 62.

Vorzugsweise ist an jedem der beiden Endbereiche 21, 22 jeweils wenigstens eine entsprechende Ausnehmung 62, 62' ausgebildet und die Rastelemente 9 des Lichtabgabeelements 11 umfassen wenigstens zwei Spannnoppen 92, 92', die an den betreffenden Gegenstellen ausgebildet sind. Im gezeigten Beispiel sind an jedem der beiden Endbereiche 21, 22 des Rahmenelements 2 jeweils zwei entsprechende Ausnehmungen 62, 62' ausgebildet und am Lichtabgabeelement 11 dementsprechend vier entsprechende Spannnoppen 92, 92'.Preferably, at least one corresponding recess 62, 62 'is formed on each of the two end regions 21, 22 and the latching elements 9 of the light-emitting element 11 comprise at least two clamping knobs 92, 92', which are connected to the are formed counterpart concerned. In the example shown, two respective recesses 62, 62 'are formed on each of the two end regions 21, 22 of the frame element 2, and correspondingly four corresponding clamping knobs 92, 92' on the light emission element 11.

Die Gestaltung der Spannnoppen 92, 92' und der Ausnehmung 62, 62' ist dabei vorzugsweise derart, dass hierdurch das Rahmenelement 2 im Rahmen-Zustand unter Zug steht.The design of the clamping knobs 92, 92 'and the recess 62, 62' is preferably such that thereby the frame member 2 is under train in the frame state.

Die Ausgestaltung der Rastelemente 6 des Rahmenelements 2 und der Rastelemente 9 des Lichtabgabeelements 11 kann auch so gewählt sein, dass die Schnappelemente 91, 91' und/oder die Spannnoppen 92, 92' nicht an dem Lichtabgabeelement 11, sondern an dem Rahmenelement 2 ausgebildet sind und die entsprechenden, damit wechselwirkenden Rastelemente an dem Lichtabgabeelement 11. Die zuerst beschriebene Ausgestaltung ist jedoch herstellungstechnisch vorteilhaft. Beispielsweise kann die Ausnehmung 62 bzw. können die Ausnehmungen 62, 62' vergleichsweise einfach durch Fräsen gebildet sein.The configuration of the latching elements 6 of the frame element 2 and the latching elements 9 of the light-emitting element 11 can also be selected so that the snap-action elements 91, 91 'and / or the clamping knobs 92, 92' are not formed on the light-emitting element 11 but on the frame element 2 and the corresponding, thus interacting latching elements on the light-emitting element 11. However, the embodiment described first is advantageous in terms of manufacturing technology. For example, the recess 62 or the recesses 62, 62 'can be comparatively easily formed by milling.

Wie aus den Figuren 4 und 5 hervorgeht, sind die Rastelemente 6 vorzugsweise an den beiden U-Schenkeln 24, 25 des Rahmenelements 2 ausgebildet, die durch die U-Form des Profilteils gegeben sind. Hierdurch lässt sich das Rahmenelement 2 besonders einfach mit einer vergleichsweise geringen Höhe h ausbilden, so dass der durch das Rahmenelement 2 gebildete Rahmen besonders schmal erscheint bzw. ist.Like from the FIGS. 4 and 5 shows, the locking elements 6 are preferably formed on the two U-legs 24, 25 of the frame member 2, which are given by the U-shape of the profile part. As a result, the frame element 2 can be formed particularly simply with a comparatively small height h , so that the frame formed by the frame element 2 appears or is particularly narrow.

Außerdem sind die Rastelemente 6 des Rahmenelements 2 vorzugsweise derart gestaltet, dass sie sich von den beiden gegenüberliegenden U-Schenkeln 24, 25 des Rahmenelements 2 mit Bezug auf die U-Form nach innen erstrecken. Hierdurch ist weiterhin ein besonders ebenmäßiges äußeres Erscheinungsbild des Rahmens ermöglicht.In addition, the locking elements 6 of the frame member 2 are preferably designed such that they extend from the two opposite U-legs 24, 25 of the frame member 2 with respect to the U-shape inwardly. As a result, a particularly even external appearance of the frame is still possible.

Die Rastelemente 9 des Lichtabgabeelements 11 sind vorzugsweise derart gestaltet, dass sie sich innerhalb der U-Form befinden, wenn sich das Rahmenelement 2 wie vorgesehen um das Lichtabgabeelement 11 herum im Rahmen-Zustand befindet.The locking elements 9 of the light-emitting element 11 are preferably designed such that they are within the U-shape when the frame element 2 as intended is around the light-emitting element 11 in the frame state.

Wenn das Lichtabgabeelement 11 aus zwei Kunststoffschalen 111, 112 besteht, können Letztere jeweils an ihren Randbereichen längs der Trennfuge einen vorzugsweise umlaufenden flanschartigen Vorsprung aufweisen, der sich jeweils innerhalb der U-Form befindet, wenn das Rahmenelement 2 wie vorgesehen im Rahmen-Zustand um das Lichtabgabeelement 11 herum angeordnet ist. Auf diese Weise lässt sich durch die U-Form ein Zusammenhalt der beiden Kunststoffschalen 111, 112 bewirken oder unterstützen.If the light-emitting element 11 consists of two plastic shells 111, 112, the latter can each have at their edge regions along the parting line a preferably circumferential flange-like projection, which is in each case within the U-shape, when the frame element 2 as provided in the frame state around the Light emitting element 11 is arranged around. In this way, a cohesion of the two plastic shells 111, 112 cause or support by the U-shape.

Die rastende Verbindung ist weiterhin vorzugsweise derart gestaltet, dass sie sich reversibel lösen und wieder herstellen lässt. Und die Sollbiegestellen 3 sind vorzugsweise für mehrmalige Biegungen ausgebildet. Hierdurch lässt sich das Rahmenelement 2 von dem Lichtabgabeelement 11 trennen und wieder an diesem befestigen. Dies kann beispielsweise für Wartungsarbeiten in einem Innenraum des Lichtabgabeelements 11 wünschenswert sein. Beim gezeigten Ausführungsbeispiel können zum Lösen des Rahmenelements 2 von dem Lichtabgabeelement 11 mithilfe eines Werkzeugs die Rastnasen 61, 61' von den entsprechenden Schnappelementen 91, 91' durch Hebeln gelöst werden.The latching connection is further preferably designed such that it can be reversibly loosened and restored. And the predetermined bending points 3 are preferably designed for repeated bends. As a result, the frame element 2 can be separated from the light-emitting element 11 and fastened to it again. This may be desirable, for example, for maintenance work in an interior of the light-emitting element 11. In the illustrated embodiment, to release the frame member 2 from the light emitting element 11 by means of a tool, the locking lugs 61, 61 'of the corresponding snap elements 91, 91' are released by levers.

Beim gezeigten Ausführungsbeispiel weist das Rahmenelement 2 weiterhin wenigstens eine Öffnung 14, beispielsweise zwei Öffnungen 14 auf, die zur Anbringung eines Aufhängemittels der Leuchte, beispielsweise in Form wenigstens eines Seiles oder wenigstens einer Pendelstange, ausgebildet ist bzw. sind.In the embodiment shown, the frame member 2 further comprises at least one opening 14, for example two openings 14, which is or are for mounting a suspension means of the lamp, for example in the form of at least one cable or at least one pendulum rod.

Das Rahmenelement 2 eignet sich nicht nur im Fall einer Rettungszeichenleuchte. Es kann beispielsweise auch zum Umfassen von Austrittsöffnungen größerer Leuchten genutzt werden.The frame member 2 is not only suitable in the case of a escape sign lamp. It can also be used for example to include outlet openings of larger lights.

Einer der Vorteile der gezeigten Lösung besteht darin, dass sich das Rahmenelement 2 auf besonders einfache Weise aus einem Aluminium-Strangpressprofil herstellen lässt. Die Nachbearbeitung des entsprechenden Profilteils zur Herstellung der Sollbiegestellen 3 und der Rastelemente 6 des Rahmenelements 2 erfordert dabei lediglich vergleichsweise geringen Aufwand. Weiterhin ist das Anbringen des Rahmenelements 2 an dem Lichtabgabeelement 11 besonders einfach und schnell möglich.One of the advantages of the solution shown is that the frame element 2 can be produced in a particularly simple manner from an aluminum extruded profile. The post-processing of the corresponding profile part for the production of the predetermined bending points 3 and the locking elements 6 of the frame member 2 requires only relatively little effort. Furthermore, the attachment of the frame member 2 to the light-emitting element 11 is particularly simple and fast.
