Description

Leuchte mit zwei Stirnteilen Luminaire with two front parts
Die vorliegende Erfindung betrifft eine Leuchte, deren Leuchtengehäuse durch ein längliches Profilelement und zwei Stirnteile gebildet ist. Das Leuchtengehäuse weist hierbei an der Längsseite eine zur Lichtabgabe vorgesehene Lichtaustrittsöffnung auf, die durch ein zumindest teillichtdurchlässiges Abdeckungsprofil und ein zwischen dem Leuchtengehäuse und Abdeckungsprofil befindliches Dichtungselement verschlossen wird.The present invention relates to a luminaire whose luminaire housing is formed by an elongated profile element and two end parts. In this case, the luminaire housing has on the longitudinal side a light exit opening provided for emitting light, which is closed by an at least partially transparent cover profile and a sealing element located between the luminaire housing and cover profile.
Leuchten, beispielsweise sogenannte Slotlightleuchten der Anmelderin, die sowohl im Deckenein-/anbau als auch in abgehängter bzw. abgependelter Weise zum Einsatz kommen, können beispielsweise ein durch ein schmales längliches Aluminiumprofil gebildetes Leuchtengehäuse aufweisen. Dabei dient das Leuchtengehäuse zur Aufnahme einer Lichtquelle und möglicherweise auch von elektronischen Steuermitteln. Das Leuchtengehäuse weist hierbei eine Öffnung in der gewünschten Abstrahlungsrichtung der Leuchte auf, die dann zumeist ein Abdeckungsprofil aufweist. Bei diesem Abdeckungsprofil kann es sich beispielsweise um einen transparenten Körper aus dem Diffusorperlmaterial PMMA (Plexiglas) handeln, der lösbar an dem Aluminiumprofil befestigt ist.Lamps, for example, so-called slotlight lamps of the Applicant, which are used both in Deckenein- / cultivation and in suspended or pendulum manner, for example, have a formed by a narrow elongated aluminum profile luminaire housing. The luminaire housing serves to receive a light source and possibly also electronic control means. The luminaire housing in this case has an opening in the desired emission direction of the luminaire, which then usually has a cover profile. This cover profile can be, for example, a transparent body made of the diffuser bead material PMMA (plexiglass), which is detachably fastened to the aluminum profile.
Um das schmale längliche Aluminiumprofil gegenüber seiner Umgebung abzudichten, kann in der Öffnung des Aluminiumsprofils eine Dichtungsaufnahme vorgesehen sein in der sich ein Dichtungselement befindet, dass an dem Abdeckungsprofil anliegt und somit eine Abdichtung der Verbindung zwischen dem Abdeckungsprofil und dem Aluminiumprofil sicherstellt.In order to seal the narrow elongated aluminum profile from its surroundings, a seal receiver can be provided in the opening of the aluminum profile in which a sealing element is located, which rests against the cover profile and thus ensures a seal between the cover profile and the aluminum profile.
An den Endkappen der schmalen länglichen Aluminiumprofile werden einfache Endkappen angebracht. Problematisch bei diesen einfachen Endkappen ist, dass durch den einfachen Autbau der Kappen die zur Lichtabgabe vorgesehene Öffnung des Aluminiumprofils nicht vollständig abgedichtet werden kann. Zusätzlich besteht das Problem, dass, aufgrund unterschiedlicher Wärmeausdehnungskoeffizienten, das längliche Aluminiumprofil im Vergleich zu dem aus Plexiglas bestehenden Abdeckungsprofil deutlich geringeren Ausdehnungen und Schrumpfungen bei Temperaturschwankungen unterliegt. So ändert sich die Länge des Abdeckungsprofils im Vergleich zu dem Aluminiumprofil auf einer Länge von 4,5 m um bis zu +/- 6 mm. Durch die verwendeten Endkappen können die entstehenden Längenunterschiede zwischen dem Abdeckungsprofil und dem länglichen Aluminiumprofil nicht ausgeglichen werden und sind somit für den Benutzer einer Leuchte sichtbar.Simple end caps are attached to the end caps of the narrow elongated aluminum profiles. The problem with these simple end caps is that due to the simple construction of the caps, the opening provided for the light emission of the aluminum profile can not be completely sealed. In addition, there is the problem that, due to different coefficients of thermal expansion, the elongated aluminum profile significantly reduces expansion and shrinkage compared to the plexiglass cover profile Temperature fluctuations subject. Thus, the length of the cover profile changes compared to the aluminum profile over a length of 4.5 m by up to +/- 6 mm. The end caps used, the resulting differences in length between the cover profile and the elongated aluminum profile can not be compensated and are thus visible to the user of a lamp.
Der vorliegenden Erfindung liegt dementsprechend die Aufgabe zugrunde, die oben beschriebene Leuchte dahingegen weiterzubilden, dass zum einen die zur Lichtabgabe vorgesehene Öffnung vollständig abgedichtet werden kann und zum anderen die durch Temperaturschwankungen entstehenden Längenunterschiede zwischen dem Abdeckungsprofil und dem länglichen Aluminiumprofil kompensiert werden können.Accordingly, it is an object of the present invention to further develop the luminaire described above in that on the one hand the opening provided for emitting light can be completely sealed and on the other hand the length differences between the cover profile and the elongated aluminum profile resulting from temperature fluctuations can be compensated.
Die Aufgabe wird durch eine Leuchte gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a luminaire according to claim 1. Advantageous developments of the invention are the subject of the dependent claims.
Erfindungsgemäß wird eine Leuchte vorgeschlagen, deren Leuchtengehäuse durch ein längliches Profilelement und zwei die Stirnseiten des Profilelements abschließende Stirnteile gebildet ist. Die Längsseite des Leuchtengehäuses weist dabei eine zur Lichtabgabe vorgesehene Lichtaustrittsöffnung auf, in der zumindest ein teillichtdurchlässiges Abdeckungsprofil lösbar befestigt ist. Zusätzlich weist die Leuchte ein zwischen dem Leuchtengehäuse und dem Abdeckungsprofil wirksames Dichtungselement auf, welches entlang der Längsseite des Leuchtengehäuses in einer Dichtungsaufnahme des Profi lelements angeordnet ist. Erfindungsgemäß weisen auch die Stirnteile eine die Dichtungsaufnahme des Profilselements weiterführende Aufnahme für das Dichtungselement auf.According to the invention, a luminaire is proposed whose luminaire housing is formed by an elongated profile element and two end parts of the end element that terminate the profile element. The longitudinal side of the lamp housing in this case has a light emission opening provided for the light emission, in which at least one part-light-permeable cover profile is releasably attached. In addition, the lamp has an effective between the lamp housing and the cover profile sealing element, which is arranged along the longitudinal side of the lamp housing in a seal holder of professional lelements. According to the invention, the end parts also have a receptacle for the sealing element which continues the sealing receptacle of the profiled element.
Durch die spezielle Ausgestaltung der Stirnteile mit einer zusätzlichen Dichtungsaufnahme, ist nun gewährleistet, dass auch an den Stirnteilen eine Abdichtung der zur Lichtabgabe vorgesehenen länglichen Öffnung stattfindet. Dies ist insbesondere auch bei einer Ausdehnung oder Schrumpfung des Abdeckungsprofils gegenüber dem länglichen Profilelement aufgrund von Temperaturschwankungen sichergestellt. Gemäß vorteilhafter Weiterbildungen der Erfindung, weist das Abdeckungsprofil eine Auflagelläche für das umlaufende Dichtungselement auf, wobei die Auflagefläche im Bereich der Stirnteile breiter als das Dichtungselement ausgestaltet ist. Zusätzlich weisen die Stirnteile einen Hohlraum auf, der mit einem Deckel verdeckt wird, wodurch die längliche Ausdehnung oder Schrumpfung des Abdeckungsprofils für den Benutzer nicht mehr sichtbar ist. Der Deckel kann vorteilhafter weise lösbar an den Stirnteilen befestigt sein.Due to the special design of the end parts with an additional seal receiving, it is now ensured that also takes place at the end portions a seal provided for the light output elongated opening. This is ensured in particular in case of expansion or shrinkage of the cover profile relative to the elongate profile element due to temperature fluctuations. According to advantageous developments of the invention, the cover profile has a bearing surface for the peripheral sealing element, wherein the bearing surface is designed to be wider than the sealing element in the region of the end parts. In addition, the end parts have a cavity which is covered with a cover, whereby the elongate expansion or shrinkage of the cover profile for the user is no longer visible. The lid can advantageously be releasably secured to the end parts.
Vorzugsweise sind die Stirnteile lösbar an dem Profilelement befestigt und weisen in den Kontaktbereichen mit dem länglichen Profilelement eine Dichtung auf. Hierdurch ist gewährleistet, dass der komplette Innenraum des Leuchtengehäuses abgedichtet werden kann, wodurch auch beispielsweise die Vorraussetzungen für die sog. Schutzart IP54 erfüllt werden können.Preferably, the end parts are releasably attached to the profile element and have in the contact areas with the elongate profile element on a seal. This ensures that the entire interior of the luminaire housing can be sealed, whereby, for example, the requirements for the so-called. Protection IP54 can be met.
Besonders vorteilhaft ist es, wenn die Stirnteile eine Druckausgleichsvorrichtung für einen Druckausgleich zwischen dem Innenraum des Leuchtengehäuses und der Umgebung vorsehen, wobei die Druckausgleichsvorrichtung aus einem Atmungsventil und einem Filterschaum, der zwischen dem Atmungsventil und dem Innenraum angebracht ist, besteht. Des Weiteren ist es vorteilhaft, wenn die Stirnteile eine Entwässerungsöffnung aufweisen um verschiedene Einbaulagen für die Leuchte zu ermöglichen.It is particularly advantageous if the end parts provide a pressure compensation device for pressure compensation between the interior of the lamp housing and the environment, wherein the pressure compensation device consists of a breathing valve and a filter foam, which is mounted between the breathing valve and the interior. Furthermore, it is advantageous if the end parts have a drainage opening to allow different mounting positions for the lamp.
Nachfolgend soll die Erfindung anhand der beiliegenden Zeichnungen näher erläutert werden. Es zeigen:The invention will be explained in more detail with reference to the accompanying drawings. Show it:

Anhand der Figuren 1-4 soll nachfolgend der Aufbau der Stirnteile 2 einer erfindungsgemäßen Leuchte 1 beschrieben werden. In den Figuren 5 und 6 wird dann die Funktionsweise der Stirnteile 2 in Verbindung mit dem Profilelement 19 beschrieben.The structure of the end portions 2 of a luminaire 1 according to the invention will be described below with reference to FIGS. 1-4. In FIGS. 5 and 6, the mode of operation of the end parts 2 in conjunction with the profile element 19 will be described.
Fig. Ia zeigt ein allgemein mit dem Bezugszeichen 2 versehenes Stirnteil, dass beispielsweise aus Kunststoff hergestellt sein kann. Das Stirnteil 2 ist dabei im Wesentlichen quaderförmig ausgebildet wobei die Quaderform im oberen Bereich abgestuft ist, wodurch sich das Gehäuse in diesem Bereich verjüngt. Diese Abstufungen 5 sind durch die Form des länglichen Profilelements 19 vorgegeben, erfüllen jedoch keine besonderen Aufgaben bei der Funktionsweise des Stirnteils 2. Die dem länglichen Profilelement 19 zugewandte Seite des quaderförmigen Stirnteils ist offen gestaltet, wo hingegen die dem länglichen Profilelement 19 abgewandte Seite verschlossen ist.Fig. Ia shows a generally provided with the reference numeral 2 front part, which may be made of plastic, for example. The front part 2 is formed substantially parallelepiped wherein the cuboid shape is stepped in the upper region, whereby the housing tapers in this area. These gradations 5 are predetermined by the shape of the elongated profile element 19, but do not fulfill any special tasks in the operation of the front part 2. The elongated profile element 19 facing side of the cuboid end portion is open, where, however, the elongated profile element 19 opposite side is closed ,
Im Innenbereich 20 des quaderförmigen Stirnteils 2 sind in den Randbereichen vier runde Stege 6 mit mittigen Löchern zur Verschraubung des Stimteils 2 an dem länglichen Profilelement 19 vorgesehen. Außerdem sind ebenfalls in den Randbereichen des Innenraums 20 des Stirnteils 2 längliche Stege 7 vorgesehen, die etwas über die Quaderform des Stirnteils 2 hervorstehen, um eine genaue Positionierung bei der Montage des Stirnteils 2 an einem länglichen Profilelement 19 zu vereinfachen. Alternativ zu einer Verschraubung wären auch andere Maßnahmen zur Befestigung der Stirnteile 2 an dem Profilelement 19 denkbar.In the inner region 20 of the cuboidal end part 2 four round webs 6 are provided with central holes for screwing the end part 2 on the elongated profile element 19 in the edge regions. In addition, 2 elongated webs 7 are also provided in the edge regions of the inner space 20 of the end part, which project slightly beyond the cuboid shape of the end part 2 in order to simplify accurate positioning during assembly of the end part 2 on an elongate profile element 19. As an alternative to a screw connection, other measures for fastening the end parts 2 to the profile element 19 would also be conceivable.
Der in Fig. Ia nach unten geöffnete quaderförmige Innenraum 20 des Stirnteils 2 ist im unteren Drittel durch einen Quersteg 8 in einen oberen Innenraum 21 und einen davon vollständig abgetrennten unteren Innenraum 9 getrennt. Der Quersteg 8 weist außerdem eine nach unten ausgerichtete Dichtungsaufnahme 4 für ein Dichtungselement 17 auf, die an der offenen Seite der Quaderform des Stirnteils 2 verläuft. Somit entsteht hinter der Dichtungsaufnahme 4 im unteren Innenraum 9 der Quaderform ein Hohlraum.In Fig. Ia downwardly open cuboidal interior 20 of the end part 2 is separated in the lower third by a transverse web 8 in an upper inner space 21 and a completely separated lower interior 9 thereof. The crossbar 8 also has a downwardly directed seal receptacle 4 for a Seal member 17 which extends on the open side of the cuboid shape of the end part 2. Thus arises behind the seal holder 4 in the lower interior 9 of the cuboid shape a cavity.
Wie in Figur Ib dargestellt, ist der obere Innenraum 21 der Quaderform des Stirnteils 2 durch ein Loch 10 mit dem unteren Innenraum 9 der Quaderform des Stirnteils 2 verbunden, wobei sich in dem unteren Innenraum 9 der Quaderform des Stirnteils 2 ein runder Steg erststreckt in dem das Loch 10 fortgeführt ist. Das Loch 10 kann als eine Art Atmungsventil angesehen werden, durch das ein Druckausgleich des Innenraums des Leuchtengehäuses mit der Umgebung möglich ist. Um nun ein Eindringen von Staub in den Innenraum der erfindungsgemäßen Leuchte 1 zu verhindern, ist in dem oberen Innenraum 21 der Quaderform des Stirnteils 2, wie in Fig. 2 dargestellt, ein Filterschaum 1 1 vorgesehen.As shown in Figure Ib, the upper inner space 21 of the cuboid shape of the end part 2 is connected through a hole 10 with the lower interior 9 of the cuboid shape of the end part 2, wherein in the lower interior 9 of the cuboid shape of the end part 2, a round web erststreckt in the the hole 10 is continued. The hole 10 can be considered as a kind of breathing valve, through which a pressure equalization of the interior of the lamp housing with the environment is possible. In order to prevent the penetration of dust into the interior of the lamp 1 according to the invention, a filter foam 1 1 is provided in the upper interior 21 of the cuboid shape of the front part 2, as shown in Fig. 2.
Des Weiteren wird der untere Innenraum 9 der Quaderform des Stirnteils 2 durch eine Öffnung 12 mit der Umgebung verbunden, die als sogenannte Entwässerungsöffnung vorgesehen ist. Hierdurch ist die Verwendung der erfindungsgemäßen Leuchte 1 mit einem derart ausgebildeten Stirnteil 2 auch in verschiedenen Einbaulagen (Wandein- und -anbau horizontal und vertikal bzw. Deckenein- und -anbau) möglich.Furthermore, the lower interior 9 of the cuboid shape of the front part 2 is connected by an opening 12 with the environment, which is provided as a so-called drainage opening. As a result, the use of the luminaire 1 according to the invention with a front part 2 designed in this way is also possible in different mounting positions (wall mounting and mounting horizontally and vertically or ceiling mounting and mounting).
Um die Abdichtung zwischen dem länglichen Profilelement 19 und dem Stirnteil 2 zu gewährleisten, ist im Rand der geöffneten Seite der Quaderform eine Dichtung 13 vorgesehen, die es ermöglicht, dass das längliche Profilelement 19 durch die Stirnteile 2 dichtend abgeschlossen werden kann.In order to ensure the sealing between the elongated profile element 19 and the front part 2, a seal 13 is provided in the edge of the open side of the cuboid shape, which allows the elongated profile element 19 can be sealed by the end parts 2.
In Fig. 2 ist nun im Gegensatz zu Fig. 1 ein mit dem Stirnteil 2 fest verbundener, schwenkbarer Deckel 3 dargestellt. Der Deckel 3 ist dabei an dem unteren Ende des Stirnteils 2 an dem der offenen Seite gegenüberliegenden Rand im offenen Zustand angebracht. Der Deckel 3 ist dabei derart angeordnet, sodass der untere Innenraum 9 im geschlossenen Zustand des Deckels 3 von unten betrachtet verdeckt ist.In FIG. 2, in contrast to FIG. 1, a hinged lid 3 fixedly connected to the front part 2 is shown. The lid 3 is attached to the lower end of the front part 2 at the opposite side of the open side in the open state. The lid 3 is arranged such that the lower interior 9 is hidden when viewed from below when the lid 3 is closed.
In Fig. 2 ist der Deckel 3 fest mit dem Stirnteil 2 verbunden. Alternativ dazu besteht aber auch die Möglichkeit, dass ein L-förmiger Deckel 15 wie in Fig. 4 dargestellt mit sogenannten Filmscharnieren 14 an dem Stirnteil 2 lösbar verbunden ist. Fig. 3 zeigt nunmehr ein Stirnteil 2 mit einem geschlossenem Deckel 3, 15. Hierbei ist zu erkennen, dass zwischen der Dichtungsaufnahme 4 und dem Deckel 3, 15 weiterhin ein Spalt besteht, dessen Höhe in etwa der Dicke eines Abdeckungsprofi Is entspricht.In Fig. 2, the lid 3 is fixedly connected to the front part 2. Alternatively, however, there is also the possibility that an L-shaped cover 15 as shown in Fig. 4 with so-called film hinges 14 on the front part 2 is detachably connected. Fig. 3 shows now a front part 2 with a closed lid 3, 15. Here it can be seen that between the seal holder 4 and the lid 3, 15 continues to be a gap whose height corresponds approximately to the thickness of a cover professional Is.
Fig. 5 zeigt nun ein an einem Profilelement 19 montiertes Stirnteil 2 in einem seitlichen Schnitt. In Fig. 6 ist die erfindungsgemäße Leuchte 1 im Querschnitt dargestellt.FIG. 5 now shows a front part 2 mounted on a profile element 19 in a lateral section. In Fig. 6, the lamp 1 according to the invention is shown in cross section.
Wie in Fig. 6 ersichtlich, weist das längliche Profilelement 19 eine Dichtungsaufnahme 18 auf, in der ein Dichtungselement 17 angebracht ist. An diesem Dichtungselement 17 liegt das Abdeckungsprofil 16 an, wodurch die zur Lichtabgabe vorgesehene Lichtaustrittsöffnung des Profilelements 19 verschlossen wird. Um nun auch an den Stirnseiten der erfindungsgemäßen Leuchte 1 die Dichtheit in diesem Bereich zu gewährleisten, geht die Dichtungsaufnahme 18 des Profilelements 19 direkt in die Dichtungsaufnahme 4 des Stirnteils 2 über. Hierdurch ist es möglich, dass ein einzelnes vollständig umlaufendes Dichtungselement 17 an dem Abdeckungsprofil 16 an einer Auflagefläche hierfür anliegt. Im Bereich der Stirnteile 2, ist diese Auflagefläche nun etwas breiter ausgestaltet, sodass auch bei einer temperaturbedingten Verschiebung des Abdeckungsprofils 16 im Verhältnis zum Profilelement 19 und dem damit verschraubten Stirnteil 2, das Dichtungselement 17 weiterhin auf der Auflagefläche des Abdeckungsprofils 16 aufliegt und dadurch auch die Dichtheit weiterhin gewährleistet ist. Wie in Fig. 5 ersichtlich, dient der untere Innenraum 9 des Stirnteils 2 hierbei insbesondere dazu, die Längsverschiebungen des Abdeckungsprofils 16 zu kompensieren.As can be seen in FIG. 6, the elongated profile element 19 has a seal receiver 18 in which a sealing element 17 is mounted. At this sealing element 17, the cover profile 16 abuts, whereby the light emission opening provided for the light-emitting opening of the profile element 19 is closed. In order to ensure the tightness in this area on the end faces of the luminaire 1 according to the invention, the seal receptacle 18 of the profile element 19 passes directly into the seal receptacle 4 of the front part 2. This makes it possible that a single completely circumferential sealing element 17 rests against the cover profile 16 on a bearing surface for this purpose. In the area of the end parts 2, this support surface is now designed slightly wider, so that even with a temperature-related displacement of the cover profile 16 in relation to the profile element 19 and the thus screwed end part 2, the sealing member 17 continues to rest on the support surface of the cover profile 16 and thereby also the Tightness is still ensured. As can be seen in FIG. 5, the lower interior 9 of the front part 2 serves in particular to compensate for the longitudinal displacements of the cover profile 16.
Damit ein Benutzer einer erfindungsgemäßen Leuchte 1 die Längsverschiebungen des Abdeckungsprofils 16 nicht wahrnimmt, wird der untere Innenraum 9, wie bereits oben ausführlich dargelegt, durch einen Deckel 3 bzw. 15 verdeckt. Somit wird die Längsverschiebung des Abdeckungsprofils 16 innerhalb des unteren Innenraums 9 kaschiert. Zur Montage bzw. Demontage des Abdeckungsprofils 16 muss nun lediglich der Deckel 3 geöffnet bzw. weggeschwenkt werden oder bei Verwendung eines nicht fest mit dem Stirnteil 2 verbundenen Deckels 15 entfernt werden. Insbesondere durch die Ausgestaltung des Stirnteils ist es nun möglich, dass die erfindungsgemäße Leuchte I beispielsweise die Vorraussetzungen für die Schutzart IP54 erfüllen kann, wodurch beispielweise auch ein Einsatz im geschützten Außenbereich möglich ist, da auch bei Temperaturschwankungen von -20 ° Grad bis + 60 ° Grad trotz der Ausdehnung oder Schrumpfung des Abdeckungspro fils 16 weiterhin eine Abdichtung der Lichtaustrittsöffnung gewährleistet ist.So that a user of a luminaire 1 according to the invention does not perceive the longitudinal displacements of the cover profile 16, the lower interior 9, as already explained in detail above, is covered by a cover 3 or 15. Thus, the longitudinal displacement of the cover profile 16 is laminated within the lower interior 9. For assembly or disassembly of the cover profile 16 now only the cover 3 must be opened or swung away or removed when using a not fixedly connected to the front part 2 cover 15. In particular, by the design of the front part, it is now possible that the lamp I according to the invention can meet, for example, the requirements for protection IP54, which for example, a use in sheltered outdoor area is possible because even with temperature variations of -20 ° degrees to + 60 ° Degree despite the expansion or shrinkage of Abdeckungspro fils 16 continues to seal the light exit opening is guaranteed.
Die in den Figuren gezeigte erfindungsgemäße Leuchte 1 und das dazugehörige Stirnteil 2 sind nur eine Ausführungsmöglichkeit der vorliegenden Erfindung. So kann beispielsweise das längliche Profilelement eine völlig andere Form aufweisen als dies hier dargestellt ist. Hierdurch würde dann auch das Stirnteil 2 eine andere dem länglichen Profilelement entsprechende Form aufweisen. The lamp 1 according to the invention shown in the figures and the associated front part 2 are only an embodiment of the present invention. For example, the elongated profile element may have a completely different shape than shown here. As a result, the front part 2 would then have a different shape corresponding to the elongated profile element.
