Abstract

A light has at least two centrally, symmetrically arranged florescent lamps (2,3) and light exit surfaces provided in the support housing parts. A supporting hollow profile (1) is arranged centrally between the end parts (5) and has inner lying receptacle space and outer lying reflection surfaces for two parallel-extending florescent lamps (2,3). The components positioned in the central carrier profile (1) continually decrease the maximum height of the lamp in the direction of the edges of the light, by approximately the thickness of the components forming the room-facing light exit surface.

Description

Die Erfindung betrifft eine Innenraumleuchte in Flachbauweise mit zumindest zwei mittensymmetrisch angeordneten, sich im Wesentlichen über die jeweilige Leuchtenlänge erstreckenden, beidendig gesockelten Leuchtstofflampen sowie in tragenden Gehäuseteilen gehalterten raum- und/oder deckenseitig gelegenen Lichtaustrittsflächen.The invention relates to an interior light in a flat construction with at least two center-symmetrically arranged, substantially over the respective length of the lamp extending, capped at both ends fluorescent lamps and supported in housing parts housing space and / or ceiling side light exit surfaces.

Leuchten dieser Art sind beispielsweise bekannt aus der EP 1 338 845 A2 und der DE 199 61 491 A1 .
Bei diesen bekannten Leuchten sind die Leuchtstofflampen in randseitig gelegenen Gehäusebereichen angeordnet und zwischen diesen zur Lampenaufnahme bestimmten seitlichen Gehäusebereichen ist zumindest raumseitig eine Lichtabstrahlfläche ausgebildet, die eine spezielle Prismengestaltung aufweist. Durch den Leuchtstofflampen zugeordnete Reflektoren wird im Zusammenwirken mit der Prismenfläche versucht, eine möglichst gleichmäßige Leuchtdichte an der Lichtabstrahlfläche zu erreichen.
Trotz des bei den bekannten Lösungen getroffenen konstruktiven Aufwands ist die erreichbare Verringerung der Bauhöhe der Leuchte durchdie erforderliche Aufnahme der Leuchtstofflampen in den seitlichen Gehäusebereichen begrenzt und außerdem lassen die erzielbare Beleuchtungsstärke und Leuchtdichtenverteilung über die Lichtabstrahlfläche der Leuchte zu wünschen übrig.Luminaires of this type are known, for example from the EP 1 338 845 A2 and the DE 199 61 491 A1 ,
In these known luminaires, the fluorescent lamps are arranged in peripherally located housing regions and between these lamp housing for particular lateral housing areas, a light emitting surface is formed at least on the room side, which has a special prism design. Reflectors associated with the fluorescent lamps, in cooperation with the prism surface, attempt to achieve as uniform a luminance as possible at the light emission surface.
Despite the constructive effort taken in the known solutions, the achievable reduction in the height of the luminaire is limited by the required uptake of the fluorescent lamps in the lateral housing areas and also the achievable illuminance and luminance distribution over the light emitting surface of the luminaire leave something to be desired.

Eine Leuchte der gattungsgemäßen Art ist ferner aus der DE 103 44 066 A1 bekannt. Diese Leuchte besitzt zwei endseitige Fassungsträger mit denen an den beiden Stirnseiten der Leuchte ein Tragrahmen verbunden ist, der einen Boden und einen gegenüber dem Boden erhabenen Rand aufweist. Der Boden ist als Lochblech ausgebildet, wobei innerhalb des erhabenen Randes auf diesem Lochblech eine lichtdurchlässige Platte aufliegt, auf der sich wiederum eine lichtstreuende Folie befindet. Mittig zwischen zwei sich über die Länge der Leuchte erstreckende Leuchtstofflampen ist ein als Mehreck-Hohlteil ausgebildeter Reflektor mit ebenen Wänden vorgesehen, in dessen Innenraum ein Vorschaltgerät aufgenommen werden kann. Zwischen den beiden Stirnwänden erstrecken sich Abdeckwandungen, die zunächst seitlich neben den Leuchtstofflampen vertikal und dann zu dem Trägerrahmen hin schräg verlaufen. Diesen Wandungen können innen liegende Reflektoren zugeordnet sein.A lamp of the generic type is further from the DE 103 44 066 A1 known. This lamp has two end fitting carrier with which at the two end faces of the lamp a support frame is connected, which has a bottom and a raised edge with respect to the bottom. The bottom is formed as a perforated plate, wherein within the raised edge on this perforated plate a translucent plate rests, on which in turn is a light-scattering film. Centered between two over the length of the lamp extending fluorescent lamps designed as a polygonal hollow part reflector is provided with flat walls, in the interior of a ballast can be added. Cover walls extend between the two end walls, which initially extend laterally next to the fluorescent lamps and then obliquely toward the support frame. These walls can be assigned inside reflectors.

Aufgabe der Erfindung ist es daher vor allem, die Leuchte sowohl unter technischen als auch unter ästhetischen Aspekten so zu gestalten, dass sie im aufgehängten Zustand ein extrem flaches Erscheinungsbild absolut minimierter Bauhöhe bietet und dabei gleichzeitig sichergestellt wird, dass zumindest raumseitig eine weitestgehend gleichmäßig ausgeleuchtete, blendungsbegrenzte Lichtabstrahlfläche für hohen Direktlichtanteil zur Verfügung steht, die nur von schmalen, streifenförmigen Gehäusebereichen begrenzt oder zum Teil begrenzt ist.The object of the invention, therefore, above all, to make the lamp both under technical and aesthetic aspects so that it offers an extremely flat appearance absolutely minimized height in the suspended state and at the same time it is ensured that at least the room side a largely uniformly illuminated, glare-limited light emission surface for high direct light component is available, which is limited only by narrow, strip-shaped housing areas or limited in part.

Gelöst wird diese Aufgabe durch den Gegenstand des Anspruchs 1.This object is achieved by the subject matter of claim 1.

Durch die Verwendung eines zentral angeordneten Träger-Hohlprofils mit hoher Durchbiegungssteifigkeit, das gleichzeitig als Multifunktionsprofil ausgebildet ist und bezüglich der benachbart angeordneten Leuchtstofflampen definierte Reflexionsflächen aufweist, gelingt es in Verbindung mit sich zum Randbereich der Leuchte hin in ihrer Höhe verringernden Lichtführungskammern, sowohl randseitig eine minimale Bauhöhe zu erreichen als auch über die gesamte raumseitige Lichtaustrittsfläche einen hohen Direktlichtanteil und gleichmäßige Lichtverteilung zu erzielen.By using a centrally arranged support hollow profile with high deflection stiffness, which is also designed as a multi-functional profile and with respect to the adjacently arranged fluorescent lamps defined reflection surfaces, it succeeds in conjunction with the edge region of the lamp down in height reducing light guide chambers, both marginally a minimum Achieve overall height as well as to achieve a high proportion of direct light and uniform light distribution over the entire room-side light exit surface.

Die raumseitige Lichtaustrittsfläche, welche die Lichtführungskammern nach unten begrenzt, besteht in ihrem Aufbau, von der Raumseite her betrachtet, bevorzugt aus einer Glas- oder einer entsprechenden Kunststoffplatte, einer Prismenplatte mit glasseitig gelegenen, insbesondere pyramidenförmigen Prismenelementen und gegebenenfalls einer sich daran anschließenden Diffusorfolie. Diese Lichtaustrittsfläche wird von den beiderseits des Hohlprofils angeordneten Leuchtstofflampen durch das Zusammenwirken zwischen den an dem Hohlprofil vorgesehenen Reflexionsflächen und den speziell gestalteten Lichtführungskammern unter Erzielung eines hohen Direktlichtanteils sehr gleichmäßig über die gesamte Fläche mit Licht beaufschlagt, wobei zu dieser Vergleichmäßigung der Lichtbeaufschlagung der Lichtaustrittsfläche auch Diffusorstreifen beitragen, die unmittelbar unterhalb der Leuchtstofflampen angeordnet sind.The room-side light exit surface, which limits the light guide chambers down, consists in its construction, viewed from the room side, preferably from a glass or a corresponding plastic plate, a prism plate with glass side located, in particular pyramidal prism elements and optionally an adjoining diffuser film. This light exit surface is acted upon by the arranged on both sides of the hollow profile fluorescent lamps by the interaction between the provided on the hollow profile reflection surfaces and the specially designed Lichtführungskammern to achieve a high direct light component very uniform over the entire surface with light, to this homogenization of the light exposure of the light exit surface and diffuser strips contribute, which are located directly below the fluorescent lamps.

Durch die Positionierung aller raumbeanspruchenden Komponenten im Mittelbereich der Leuchte und die ausgeprägte Reduzierung der Leuchtenhöhe zu den Randseiten hin, befindet sich der Mittelbereich der Leuchte im aufgehängten Zustand der Leuchte auch bei seitlicher Sichtlinie praktisch stets im Sichtschatten, so dass von der Leuchte nur die raumseitige Lichtaustrittsfläche mit den ungewöhnlich schmalen Randbereichen wahrgenommen wird, was zu einem ästhetisch äußerst ansprechenden flachen Erscheinungsbild der Leuchte führt.Due to the positioning of all raumbeanspruchenden components in the central region of the lamp and the pronounced reduction of the luminaire height to the edge sides, the central region of the luminaire in the suspended state of the lamp is practically always in the visual shadow even with lateral line of sight, so that of the lamp only the room-side light exit surface is perceived with the unusually narrow edge areas, resulting in an aesthetically pleasing flat appearance of the lamp.

Vorzugsweise erstreckt sich der mittig gelegene Bereich maximaler Höhe, in dem sich das Trägerhohlprofil befindet, etwa über ein Viertel der Gesamtbreite der Leuchte, und die Höhe der Randleisten bzw. Höhe des die Leuchte randseitig begrenzten Rahmens beträgt weniger als 20% der maximalen Höhe der Leuchte. Diese geringe Randhöhe ist im Wesentlichen vorgegeben durch die Materialstärke der zur Bildung der Lichtaustrittsfläche verwendeten Komponenten.Preferably, the central region of maximum height, in which the carrier hollow profile is located, extends over approximately one quarter of the total width of the luminaire, and the height of the edge strips or height of the frame bordering the luminaire is less than 20% of the maximum height of the luminaire , This small edge height is essentially predetermined by the material thickness of the components used to form the light exit surface.

Das mittensymmetrisch ausgebildete Multifunktionsträgerprofil besitzt der jeweiligen Leuchtstofflampe zugewandt eine erste konkave Reflexionsfläche und eine sich daran anschließende zweite konkave Reflexionsfläche. Die erste Reflexionsfläche ist dabei so gerichtet, dass sie Licht insbesondere in die ihr zugeordnete Lichtführungskammer und/oder zur Erzielung eines indirekten Lichtanteils zur Deckenseite richtet, während die zweite Reflexionsfläche das auftreffende Licht vorwiegend in Richtung der raumseitigen Lichtaustrittsfläche leitet bzw. über die Lichtaustrittsfläche verteilt.The centrally symmetrical multifunction carrier profile, facing the respective fluorescent lamp, has a first concave reflection surface and an adjoining second concave reflection surface. The first reflection surface is directed in such a way that it directs light in particular into the light guide chamber assigned to it and / or to achieve an indirect light component to the ceiling side, while the second reflection surface guides the incident light mainly in the direction of the room-side light exit surface or distributed over the light exit surface.

Während der Innenraum des Trägerhohlprofils zur Aufnahme von Funktionskomponenten wie z.B. einem Vorschaltgerät dient, ist bevorzugt die gesamte Außenfläche des Trägerprofils als Reflexionsfläche genutzt, wobei das raumseitige, als Spitze ausgebildete Ende dieses Hohlprofils unmittelbar benachbart der raumseitigen Lichtaustrittsfläche gelegen ist, um alle Möglichkeiten zur Minimierung der Gesamthöhe der Leuchte zu nutzen.While the interior of the carrier hollow profile for receiving functional components such. serves a ballast, the entire outer surface of the carrier profile is preferably used as a reflection surface, wherein the room-side, designed as a tip end of this hollow profile is located immediately adjacent the room-side light exit surface to use all possibilities for minimizing the overall height of the lamp.

Da eine erfindungsgemäße Leuchte eine Länge von mehr als 3 m besitzen kann, ist es von Bedeutung, dass das verwendete Trägerprofil eine hohe Durchbiegungssteifigkeit besitzt. Die erwünschte hohe Durchbiegungssteifigkeit wird durch die gewählte Querschnittsform des Profils einerseits sowie andererseits dadurch erreicht, dass in das Hohlprofil Abschnitte eines Versteifungsprofils eingeklipst werden können, die zu einer versteifenden Mehrkammerstruktur führen. Außerdem ist die oben offene Seite des Trägerprofils durch einen streifenförmigen Versteifungsdeckel verschließbar, so dass insgesamt eine ungewöhnlich biegesteife Gesamtanordnung entsteht.Since a lamp according to the invention may have a length of more than 3 m, it is important that the carrier profile used has a high deflection stiffness. The desired high deflection stiffness is achieved by the selected cross-sectional shape of the profile on the one hand and on the other hand, in that sections of a stiffening profile can be clipped into the hollow profile, which lead to a stiffening multi-chamber structure. In addition, the top open side of the carrier profile can be closed by a strip-shaped stiffening lid, so that overall an unusually rigid overall arrangement arises.

Die seitlich der jeweiligen Leuchtstofflampe gelegenen Lichtführungskammern bestehen aus transparentem Material und sind bevorzugt über eine bodenseitige Verbindungswand zu einem einteiligen Bauteil verbunden.The light guide chambers located laterally of the respective fluorescent lamp are made of transparent material and are preferably connected to a one-piece component via a bottom-side connecting wall.

Da die raumseitige Direktlichtaustrittsfläche sowohl direkt von den Leuchtstofflampen mit Licht beaufschlagt wird als auch eine indirekte Beaufschlagung über Reflexionslicht erfolgt, besteht die Möglichkeit, durch Verwendung von reflektierenden und/oder streuenden und/oder teildurchlässigen oder total reflektierenden Beschichtungen oder Folien und/oder eingelegte oder integrierte lineare Prismenstrukturen gezielt eine jeweils optimale Lichtverteilung zu realisieren, wobei Licht nicht nur über die raumseitige Lichtaustrittsfläche gleichmäßig verteilbar ist, sondern auch ein frei wählbarer Anteil an Licht zur Deckenseite geleitet werden kann.Since the room-side direct light exit surface is exposed to light both directly from the fluorescent lamps and an indirect exposure to reflected light, it is possible by using reflective and / or scattering and / or partially transparent or totally reflective coatings or films and / or inserted or integrated linear prism structures targeted to realize each optimum light distribution, with light not only on the room-side light exit surface is evenly distributed, but also a freely selectable proportion of light can be passed to the ceiling side.

Zu der jeweils gewünschten Lichtverteilung trägt auch der oberhalb der Leuchtstofflampen gelegene Bereich zwischen dem Trägerprofil und den Lichtführungskammern bei, der durch eine zumindest teilweise lichtdurchlässige und/oder zumindest teilweise reflektierende und/oder streuende Abdeckung verschließbar ist, wobei zu diesem Zweck die Abdeckung mit entsprechend geeigneten Folien, Beschichtungen oder Prismenstrukturen kombinierbar ist. Die bevorzugt linearen und quer zur Längserstreckung der Leuchte verlaufenden Prismenstrukturen können auch mit der Abdeckung integriert ausgebildet und insbesondere außenseitig vorgesehen sein.The area between the carrier profile and the light guiding chambers situated above the fluorescent lamps also contributes to the respective desired light distribution, which can be closed by an at least partially translucent and / or at least partially reflecting and / or diffusing cover, the cover being suitably suitable for this purpose Foils, coatings or prismatic structures can be combined. The preferably linear and transverse to the longitudinal extension of the luminaire prismatic structures can also be integrated with the cover formed and in particular provided on the outside.

Die Aufhängung der jeweiligen Leuchte erfolgt über die beidendig vorgesehenen Endteile, die mit dem Trägerprofil verschraubt sind, die Lampenfassungen tragen und außerdem Formschlussverbindungen mit den übrigen Leuchtenkomponenten gewährleisten.The suspension of the respective lamp via the end portions provided at both ends, which are bolted to the carrier profile, carry the lamp holders and also ensure form-fitting connections with the other lighting components.

Eine bevorzugte Ausführungsform der Leuchte nach der Erfindung zeichnet sich dadurch aus, dass einer vorgegebenen Lampen- und Trägerprofillänge mehrere in sich gleiche Einzelmodule in Form eines Trägerrahmens für die Komponenten der Lichtaustrittsflächen sowie für die Lichtleitkammern und gegebenenfalls weitere Abdeckorgane zugeordnet sind, wobei die einzelnen Module über stabilisierende Koppelelemente miteinander verbindbar sind, welche die Lichtaustrittsfläche raumseitig nach Art von Querstegen unterteilen.A preferred embodiment of the luminaire according to the invention is characterized in that a predetermined lamp and Trägerprofillänge several self-contained individual modules are assigned in the form of a support frame for the components of the light exit surfaces and for the Lichtleitkammern and optionally other Abdeckorgane, wherein the individual modules on Stabilizing coupling elements are connected to each other, which subdivide the light exit surface on the room side in the manner of transverse webs.

Diese modulare Ausgestaltung führt nicht nur zu einem in sich besonders stabilen Gesamtaufbau, sondern es wird auf diese Weise erreicht, dass Leuchten unterschiedlicher Länge, die durch die verwendeten Leuchtstofflampen und das zugehörige Trägerprofil vorgegeben ist, aus den Einzelmodulen aufgebaut werden können, wobei die Teilung der Module an die gängigen Lampenlängen angepasst ist.This modular design not only leads to a particularly stable overall structure, but it is achieved in this way that lights of different lengths, which is determined by the fluorescent lamps used and the associated support profile can be constructed from the individual modules, the division of Modules adapted to the common lamp lengths.

Eine problemlose Aneinanderreihung von Modulen ist dadurch gewährleistet, dass jeder in sich geschlossen ausgebildete Trägerrahmen stirnseitig jeweils ein profiliertes, zumindest zum Teil der Form der Lichtführungskammern angepasstes Rahmenstegteil aufweist und jeweils zwei aneinandergrenzende Rahmenstegteile über ein Koppel-Stegteil form- und kraftschlüssig miteinander verbindbar sind.A trouble-free juxtaposition of modules is ensured by the fact that each self-contained support frame frontally each have a profiled, at least partially adapted to the shape of the Lichtführungskammern Rahmenstegteil and two adjacent frame web parts via a coupling web part form and locks are connected to each other.

Alternativ zu der Verwendung eines in sich geschlossen ausgebildeten Trägerrahmens in Verbindung mit den Einzelmodulen können die Einzelmodule auch jeweils gebildet werden von zu einer Baueinheit zusammengefassten transparenten Lichtführungskammern, an die stirnseitig ebenfalls transparente Anschlussstegteile angeformt sind. Aneinandergrenzende Module werden unter Verwendung eines die raumseitige Lichtaustrittsfläche querstegartig unterteilenden Koppel-Stegteils miteinander verbunden, wobei das Koppel-Stegteil form- und kraftschlüssig mit den an den Lichtführungskammern vorgesehenen Rahmenstegteilen befestigt, insbesondere verschraubt wird. Die Rahmenstegteile greifen dabei zur Gewährleistung der Formschlussverbindung in entsprechende Ausnehmungen im Koppel-Stegteil ein, so dass die sonst übliche Koppeldistanz entfallen kann. Da überdies die an die Lichtführungskammern angeformten Rahmenstegteile transparent sind, sind in diesem Falle an der raumseitigen Lichtaustrittsfläche nur die diese Lichtaustrittsfläche querstegartig unterteilenden Koppel-Stegteile als nicht lichtdurchlässige Elemente sichtbar.As an alternative to the use of a self-contained support frame in conjunction with the individual modules, the individual modules can also be formed in each case by transparent light guide chambers combined to form a structural unit, to which end face also transparent connecting web parts are integrally formed. Adjoining modules are connected to one another using a coupling web portion which divides the room-side light exit surface in a transverse manner, wherein the coupling web portion is positively and non-positively attached to the frame web portions provided on the light guiding chambers, in particular screwed. The frame web parts engage to ensure the positive connection in corresponding recesses in the coupling web portion, so that the usual coupling distance can be omitted. Moreover, since the frame web parts formed on the light guiding chambers are transparent, only the coupling web parts dividing the web-like cross-section in this case are visible on the room-side light exit surface as non-translucent elements.

Die Randleisten können entweder als separate Elemente ausgebildet oder randseitig einteilig an die lichtdurchlässige Platte angeformt sein, die die Lichtaustrittsfläche raumseitig begrenzt. Die Randleisten können auch einteilig an die Lichtführungskammern angeformt sein, wobei in diesem Falle die die Lichtaustrittsfläche bildenden Komponenten seitlich in die diese Komponenten führenden Randleisten einzuschieben sind.The edge strips can either be formed as separate elements or edge integrally formed on the translucent plate, which limits the light exit surface on the room side. The edge strips can also be integrally formed on the light guide chambers, in which case the components forming the light exit surface are laterally inserted into the edge strips guiding these components.

Diese Ausgestaltungen eröffnen insbesondere die Möglichkeit, im Falle separater Randleisten unterschiedliche Arten von Randleisten, z.B. transparente oder unterschiedlich farbige Randleisten zu verwenden, während bei direkt angeformten Randleisten diese im Regelfall transparent sind, so dass die Leuchte randseitig keine lichtundurchlässige Begrenzung aufweist. Bei den ohne in sich geschlossenen Rahmen ausgeführten Leuchten sind die mit den Koppel-Stegteilen zu verbindenden Rahmenstegteile einteilig mit den Lichtführungskammern ausgebildet und entsprechend diesen Kammern transparent. Dies führt in der raumseitigen Ansicht der Leuchte dazu, dass als die Leuchte in Querrichtung unterteilende Stege im Wesentlichen nur die die Rahmenstegteile formschlüssig aufnehmenden Koppel-Stegteile sichtbar in Erscheinung treten.In particular, these embodiments offer the possibility, in the case of separate edge strips, of different types of edge strips, e.g. transparent or differently colored edge strips to use, while in directly molded edge strips these are usually transparent, so that the edge of the light has no opaque boundary. In the case of the luminaires without closed frames, the frame web parts to be connected to the coupling web parts are integrally formed with the light guiding chambers and transparent according to these chambers. This leads in the room-side view of the lamp to the fact that as the luminaire in the transverse direction dividing webs substantially only the frame web parts positively receiving coupling web parts visible in appearance.

Besonders vorteilhaft ist es im Rahmen der Erfindung, dass zur Schaffung von sich zwischen zwei Endteilen erstreckenden Lichtbandanordnungen modular oder nicht modular aufgebaute Einzelleuchten über beidseitig Fassungshalter für Leuchtstofflampen aufweisende Zwischenträger miteinander verschraubbar sind, wobei diese vorzugsweise mit einer Aufhängung verbundenen Zwischenträger an der raumseitigen Lichtaustrittsfläche Querstege analog den Koppel-Stegteilen der Einzelmodule bilden.It is particularly advantageous in the context of the invention that for the creation of extending between two end portions light band assemblies modular or non-modular single luminaires on both sides frame holder for fluorescent lamps having intermediate carrier screwed together, these preferably connected to a suspension intermediate carrier on the room side light exit surface transverse webs analog form the coupling web parts of the individual modules.

Durch die auf diese Weise ermöglichte Aneinanderreihung von modular oder nicht modular aufgebauten Einzelleuchten lassen sich in ästhetischer Hinsicht ungewöhnlich leicht wirkende Lichtbänder mit hinsichtlich der sichtbaren Rahmenteile durchgängig gleichmäßiger Struktur schaffen.In this way, the juxtaposition of modular or non-modular individual luminaires, which is made possible in this way, makes it possible to create unusually light-acting light bands with a structure which is uniform in terms of the visible frame parts.

Die Querschnittsansicht nach Fig. 1 zeigt eine bevorzugte Ausgestaltung des zentralen Trägerhohlprofils 1, das zwischen zwei Leuchtstofflampen 2, 3 positioniert ist, welche beidendig in Fassungen 4 aufgenommen sind, die an entsprechenden Leuchtenendteilen 5 angebracht sind. Die Wandungen des Trägerprofils 1 sind - von außen betrachtet - konkav ausgebildet, wodurch das Trägerprofil zu einem Multifunktionsprofil wird, da es nicht nur tragende Funktion und im Hinblick auf seinen Innenraum 17 Aufnahmefunktion für Vorschaltgeräte und dergleichen besitzt, sondern seine Außenflächen gleichzeitig als Reflexionsflächen genutzt sind, wozu gegebenenfalls eine entsprechende Beschichtung oder Belegung mit reflektierenden Folien vorgesehen sein kann. Diese Ausgestaltung als Multifunktionprofil gewährleistet, dass dieses Trägerprofil 1 und die zugehörigen integrierten Elemente zwischen den zwei Leuchtstofflampen angeordnet werden können.The cross-sectional view after Fig. 1 shows a preferred embodiment of the central carrier hollow profile 1, which is positioned between two fluorescent lamps 2, 3, which are accommodated at both ends in sockets 4, which are attached to corresponding lamp end parts 5. The walls of the carrier profile 1 are - viewed from the outside - concave, whereby the carrier profile is a multi-functional profile, since it not only supporting function and in terms of its interior 17 recording function for ballasts and the like, but its outer surfaces are used simultaneously as reflective surfaces for which purpose, if appropriate, a corresponding coating or coating with reflective foils can be provided. This embodiment as a multi-functional profile ensures that this support profile 1 and the associated integrated elements between the two fluorescent lamps can be arranged.

Auf jeder Seite des mittensymmetrisch ausgebildeten Trägerprofils 1 befinden sich demgemäß eine erste Reflexionsfläche 18 bzw. 20, jeweils benachbart der zugehörigen Leuchtstofflampe 2, 3, und eine zweite Reflexionsfläche 19 bzw. 21. Die Achsen der jeweils ersten und zweiten Reflexionsflächen schließen zwischen sich beispielsweise einen Winkel von etwa 90° ein. Die jeweiligen zweiten Reflexionsflächen 19, 21 sind so gerichtet, dass das von ihnen reflektierte Licht über die raumseitig gelegene Lichtaustrittsfläche 13 verteilt wird.On each side of the center symmetrically formed carrier profile 1 are accordingly a first reflection surface 18 and 20, respectively adjacent to the associated fluorescent lamp 2, 3, and a second reflection surface 19 and 21. The axes of the respective first and second reflection surfaces close between them, for example Angle of about 90 °. The respective second reflection surfaces 19, 21 are directed such that the light reflected by them is distributed via the light exit surface 13 located on the side of the room.

Jeweils seitlich der beiden Leuchtstofflampen 2, 3 befinden sich im Querschnitt die Form von etwa spitzwinkligen Dreiecken besitzende Lichtführungskammern 6, 7, die bevorzugt zumindest im Wesentlichen aus transparentem Material bestehen, die Wahl eines vorgebbaren Verlaufs der Deckwand 27 zulassen und über eine bodenseitige Verbindungswand 29 zu einem einteiligen Bauteil zusammengefasst sind.In each case laterally of the two fluorescent lamps 2, 3 are in cross-section the shape of about acute triangles possessing Lichtführungskammern 6, 7, preferably at least substantially made of transparent material, allow the choice of a predetermined course of the top wall 27 and a bottom-side connecting wall 29 a one-piece component are summarized.

Raumseitig befindet sich unterhalb der Lichtführungskammern 6, 7 - sowie der sie verbindenden Wand 29 - von der Raumseite her gesehen - eine Glas- oder entsprechend transparente Kunststoffplatte 8, eine Prismenplatte 9 und eine sich jeweils daran anschließende Diffusorfolie 10. Die Prismenplatte 9 dient zur Erzielung des geforderten Ausblendeffekts, wobei die vorzugsweise pyramindenförmigen Prismen auf der Seite der Glasplatte gelegen sind und diese Glasplatte damit gleichzeitig die Prismen vor Verschmutzung schützt und eine glatte, leicht zu reinigende Außenfläche gewährleistet.The room side is below the light guide chambers 6, 7 - as well as the connecting wall 29 - seen from the room side - a glass or correspondingly transparent plastic plate 8, a prism plate 9 and a respectively adjoining diffuser film 10. The prism plate 9 is used to achieve the required Ausblendeffekts, the preferably pyramidal prisms are located on the side of the glass plate and this glass plate thus simultaneously protects the prisms from contamination and ensures a smooth, easy to clean outer surface.

Aufgenommen sind die Komponenten 8, 9, 10 sowie die Lichtführungskammern 6, 7, 29 in einem Trägerrahmen 11, dessen für das Erscheinungsbild der Leuchte wesentliche Höhe minimiert und praktisch nur durch die Materialstärken der die Lichtaustrittsfläche 13 bildende Komponenten 8, 9, 10 bestimmt ist.
Gehalten wird dieser Trägerrahmen 11 in den Endteilen 5 und im Falle eines im Einzelnen noch zu erläuternden modularen Aufbaus der Leuchte in zusätzlichen Koppel-Stegteilen.The components 8, 9, 10 and the light guide chambers 6, 7, 29 are accommodated in a support frame 11, the height of which is minimized for the appearance of the luminaire and practically determined only by the material thicknesses of the components 8, 9, 10 forming the light exit surface 13 ,
This support frame 11 is kept in the end parts 5 and in the case of a still to be explained in detail modular construction of the lamp in additional coupling web parts.

Zur Vergleichmäßigung der Leuchtdichte und zur Erzielung eines hohen Direktlichtanteils an der raumseitigen Lichtaustrittsfläche 13 tragen nicht nur die speziell am Trägerprofil vorgesehenen Reflexionsflächen bei, sondern auch unmittelbar unterhalb der Leuchtstoffröhren 2, 3 in entsprechenden Ausnehmungen der Verbindungswand 29 vorgesehene Diffusorstreifen 22 sowie an der Deckwand 27 der Lichtführungskammern 6, 7 bzw. der Abdeckung 23 je nach Bedarf entweder innen- oder außenseitig vorgesehene Reflexions- und/oder Prismenflächen 26, wobei die Prismenflächen vorzugsweise linear strukturiert sind und die linearen Prismenelemente quer zur Längsrichtung der Leuchte verlaufen. Die Prismen, die auch in das jeweilige lichtdurchlässige Element integriert sein können, sind nach außen gerichtet und durch eine geeignete Deckfläche abgedeckt, so dass nach außen hin stets eine vor Verschmutzung schützende glatte Fläche vorliegt, die auch problemlos gereinigt werden kann. Speziell können in diesem Zusammenhang Umkehrprismatikfolien Verwendung finden, aber es ist anstelle der Verwendung entsprechender Folien auch möglich, die Prismen integriert mit den jeweiligen transparenten Wandungen bzw. Wandungsbereichen auszubilden.To even out the luminance and to achieve a high proportion of direct light on the room-side light exit surface 13 contribute not only the specially provided on the support profile reflection surfaces, but also directly below the fluorescent tubes 2, 3 provided in corresponding recesses of the connecting wall 29 diffuser strip 22 and on the top wall 27 of Lichtführungskammern 6, 7 and the cover 23 as needed either inside or outside provided for reflection and / or prism surfaces 26, wherein the prism surfaces are preferably linearly structured and the linear prism elements extend transversely to the longitudinal direction of the lamp. The prisms, which may also be integrated into the respective translucent element, are directed outwards and covered by a suitable cover surface, so that there is always a protective surface against contamination smooth surface, which can also be easily cleaned. In particular reversible prismatic films may be used in this connection, but instead of using corresponding films, it is also possible to form the prisms integrated with the respective transparent walls or wall regions.

Durch die Wahl der Lichtdurchlässigkeit der Deckwand 27 der Lichtführungskammern 6, 7 kann der Anteil des zur Decke hin gerichteten indirekten Lichtes ebenso beeinflusst werden wie durch Wahl einer mehr oder weniger lichtdurchlässigen oder auch reflektierenden Abdeckung 23 oberhalb der Leuchtstofflampen 2, 3. Dazu kann an der Innenseite dieser Abdeckung 23 eine geeignete Folie 24 oder Prismenfolie oder eine integrierte Prismenstruktur vorgesehen sein, so dass die im Einzelfall gewünschten deckenseitigen Lichtaustrittsflächen 14, 15 erhalten werden.By choosing the translucency of the top wall 27 of the light guide chambers 6, 7, the proportion of directed towards the ceiling indirect light can be influenced as well as by choosing a more or less translucent or reflective cover 23 above the fluorescent lamps 2, 3. This can at the Inside this cover 23 may be provided a suitable film 24 or prismatic film or an integrated prismatic structure, so that in each case desired ceiling-side light exit surfaces 14, 15 are obtained.

Die Aufhängung der Leuchte erfolgt über bevorzugt mit Seilen zusammenwirkenden Aufhängemitteln 12, die mit den Endteilen 5 verbunden werden können.The suspension of the lamp via preferably cooperating with ropes hangers 12, which can be connected to the end portions 5.

Es wurde bereits darauf hingewiesen, dass bezüglich des Trägerprofils 1 eine hohe Durchbiegesteifigkeit gefordert wird, da Leuchten mit einer Länge von mehreren Metern realisiert werden können und dazu entsprechend lange durchgehende Hohlprofile erforderlich sind. Um die Durchbiegesteifigkeit zu erhöhen, sind in das Hohlprofil 1 Abschnitte eines Versteifungsprofils 16 einschnappbar, die in Verbindung mit einem ebenfalls einschnappbar ausgebildeten Versteifungsdeckel 25 zu einer Mehrkammerstruktur des Profils führen, die sich durch besonders hohe Steifigkeit auszeichnet.It has already been pointed out that, with regard to the carrier profile 1, a high degree of flexural rigidity is required since lamps with a length of several meters can be realized and correspondingly long continuous hollow profiles are required. In order to increase the flexural rigidity, sections of a stiffening profile 16 can be snapped into the hollow profile 1, which, in conjunction with a stiffening cover 25 which is likewise snap-fit, lead to a multi-chamber structure of the profile, which is characterized by particularly high rigidity.

Der Fig. 1, die hinsichtlich der Relativabmessungen ein maßstabsgetreues Abbild einer konkret ausgeführten erfindungsgemäßen Leuchte ist, lässt sich auch entnehmen, dass der mittig gelegene Bereich maximaler Höhe sich etwa über ein Viertel der Gesamtbreite der Leuchte erstreckt und dass die Höhe des randseitigen Rahmens 11 weniger als 20% der maximalen Leuchtenhöhe beträgt. Im Hinblick auf die durch diese Abmessungsrelationen erzielten Vorteile ist noch von Bedeutung, dass die Deckwand 27 der Lichtführungskammern 6, 7 seitlich in einen Randstreifen 28 übergeht, der auf den Komponenten der Lichtaustrittsfläche 13 aufliegt.Of the Fig. 1 , which is a scale representation of a concretely designed luminaire according to the invention with regard to the relative dimensions, it can also be seen that the centrally located area of maximum height extends approximately over a quarter of the total width of the luminaire and that the height of the peripheral frame 11 is less than 20% maximum luminaire height is. With regard to the advantages achieved by these dimensional relationships, it is also of importance that the top wall 27 of the light guiding chambers 6, 7 merges laterally into an edge strip 28 which rests on the components of the light exit surface 13.

Auch dies trägt dazu bei, dass bei aufgehängter Leuchte unter den üblichen Betrachtungswinkeln lediglich die Lichtaustrittsfläche 19 und der Trägerrahmen 11 von sehr geringer Höhe sichtbar sind, während der gesamte darüber liegende Aufbau im Sichtschatten liegt und damit die mittig gelegenen funktionellen Komponenten der Leuchte nicht störend in Erscheinung treten.This also contributes to the fact that with suspended luminaire under the usual viewing angles, only the light exit surface 19 and the support frame 11 are visible from very low height, while the entire overlying structure lies in the visual shadow and thus does not interfere with the centrally located functional components of the luminaire Appear appearance.

Die perspektivische Teilansicht nach Fig. 2 zeigt eine Ausführungsform der Erfindung, bei der die bereits anhand der Fig. 1 erläuterten Komponenten verwendet sind und bei der sich insbesondere auch die Lichtführungskammern 6, 7 mit ihren lichtdurchlässigen Wandungen 27, 30 über die gesamte Länge der Leuchte erstrecken. Die Randleisten 11, die aus transparentem oder farblich unterschiedlichem Material bestehen können, sind mit den Endteilen 5 fest verbunden und nehmen die die Lichtaustrittsfläche 13 bildenden flächigen Komponenten sowie den Randbereich der Deckwand 27 der Lichtführungskammern 6, 7 auf.The perspective partial view after Fig. 2 shows an embodiment of the invention, in which already with reference to the Fig. 1 explained components are used and in which in particular the light guide chambers 6, 7 extend with their translucent walls 27, 30 over the entire length of the lamp. The edge strips 11, which may consist of transparent or different color material, are fixedly connected to the end portions 5 and take the light-emitting surface 13 forming planar components and the edge region of the top wall 27 of the light guide chambers 6, 7.

Eine besonders vorteilhafte Ausführungsform der Erfindung ist in der perspektivischen Teilansicht nach Fig. 3 zu sehen. Es handelt sich dabei um eine Ausführungsform, bei der die Leuchte aus untereinander identisch ausgebildeten Teilen modular aufgebaut ist.A particularly advantageous embodiment of the invention is shown in the perspective partial view Fig. 3 to see. It is an embodiment in which the lamp is constructed modularly from each other identically formed parts.

Auch bei dieser Ausführungsform ist ein über die Länge der Leuchte durchgehendes Trägerhohlprofil 1 von der bereits beschriebenen Art verwendet, das sich zwischen zwei Endteilen 5 erstreckt. Der Leuchtenaufbau besteht jedoch aus mehreren identischen Einzelmodulen 33. Die Einzelmodule 33 können dabei in unterschiedlicher Weise ausgestaltet sein. Nach einer ersten Ausgestaltung umfasst ein Einzelmodul 33 jeweils einen in sich geschlossenen Trägerrahmen 11 für die Komponenten der Lichtaustrittsfläche 13 sowie für die wiederum bevorzugt zu einer Einheit zusammengefassten Lichtleitkammern 6, 7. Jeder der in sich geschlossen ausgebildeten Trägerrahmen 11 besitzt in diesem Falle stirnseitig jeweils ein profiliertes, der Form der Lichtführungskammern 6, 7 etwa angepasstes Rahmenstegteil 31. Beim Aufbau der Leuchte werden jeweils zwei aneinandergrenzende Rahmenstegteile 31 benachbarter Module 33 über ein Koppel-Stegteil 32 form- und kraftschlüssig miteinander verbunden, wodurch insgesamt eine sehr stabile Gesamtanordnung entsteht. Die Rahmenstegteile 31 und das jeweils dazwischen liegende Koppel-Stegteil 32 sind an der raumseitigen Lichtaustrittsfläche 13 sichtbar und strukturieren damit diese Lichtaustrittsfläche 13 zusammen mit den außen liegenden Rahmen-Randleisten. Das Ausmaß der Sichtbarkeit der Rahmenstegteile 31 kann durch die Eingriffstiefe der Rahmenstegteile in die sie formschlüssig aufnehmenden Koppel-Stegteile 32 vorgegeben werden.Also in this embodiment, a continuous over the length of the lamp carrier profile 1 is used of the type already described, which extends between two end portions 5. However, the luminaire structure consists of several identical individual modules 33. The individual modules 33 can be designed in different ways. According to a first embodiment, a single module 33 each comprises a self-contained support frame 11 for the components of the light exit surface 13 and for the turn preferably combined into a unit Lichtleitkammern 6, 7. Each of the self-contained support frame 11 has in this case the front one each Profiled, the shape of the light guide chambers 6, 7 approximately adapted frame web portion 31. In the construction of the lamp two adjacent frame web portions 31 adjacent modules 33 are positively and non-positively connected via a coupling web portion 32, creating a very stable overall arrangement. The frame web parts 31 and the respectively intermediate coupling web part 32 are visible on the room-side light exit surface 13 and thus structure this light exit surface 13 together with the outer frame edge strips. The extent of visibility of the frame web parts 31 can be specified by the engagement depth of the frame web parts in the form-fitting receiving coupling web parts 32.

Gemäß einer modifizierten und vereinfachten Ausführungsvariante sind die Rahmenstegteile einteilig an die Stirnseiten der Lichtleitkammern 6, 7 angeformt und ebenfalls transparent ausgebildet. Die Verbindung der einzelnen Module untereinander erfolgt wiederum jeweils über ein Koppel-Stegteil, das mit den Rahmenstegteilen von aufeinander folgenden Modulen wiederum form- und kraftschlüssig verbindbar.According to a modified and simplified embodiment, the frame web parts are integrally formed on the end faces of the Lichtleitkammern 6, 7 and also formed transparent. The connection of the individual modules with each other again takes place via a coupling web part, which in turn can be positively and non-positively connected to the frame web parts of successive modules.

Wenn die zur Halterung der die raumseitige Lichtaustrittsfläche bildenden Komponenten erforderlichen Randleisten nicht direkt an die die Lichtführungskammern umfassende Baueinheit angeformt sind oder wenn diese Randleisten nicht an die die Lichtaustrittsfläche raumseitig begrenzende lichtdurchlässige Platte angeformt sind, können insbesondere Randleisten aus unterschiedlichem Material und unterschiedlicher Farbgebung Verwendung finden, wobei in diesem Falle die raumseitige Sichtfläche der Leuchte nur durch die Randleisten und durch die Koppel-Stegteile strukturiert wird, da die transparenten, mit den Lichtleitkammern einteilig ausgebildeten Rahmenstegteile nicht oder nur unwesentlich in Erscheinung treten.If the edge strips required for holding the components forming the room-side light exit surface are not formed directly on the unit comprising the light guide chambers or if these edges are not formed on the translucent panel delimiting the light exit surface, in particular edge strips of different material and different colors can be used. in which case the room-side visible surface of the luminaire is structured only by the edge strips and by the coupling web parts, since the transparent, integrally formed with the Lichtleitkammern frame web parts not or only slightly appear in appearance.

Nach einer weiteren Ausgestaltung können die Randleisten einteilig an die raumseitig gelegene transparente Platte der Lichtaustrittsfläche angeformt sein, so dass sich eine Lichtaustrittsfläche ergibt, die strukturell nur durch die von den Koppel-Stegteilen herrührenden Querstege unterteilt ist.According to a further embodiment, the edge strips can be integrally formed integrally on the room side located transparent plate of the light exit surface, so that there is a light exit surface, which is structurally divided only by the originating from the coupling web parts transverse webs.

Fig. 4 zeigt eine Ansicht einer Leuchte mit dem Grundaufbau nach Fig. 3 von der Deckenseite her, während
Fig. 5 eine raumseitige Ansicht dieser Leuchte ohne raumseitige Prismatikfläche 9 zeigt und die gewünschte formale Unterteilung der Lichtaustrittsfläche 13 durch die Querstege 31, 32 erkennen lässt. Fig. 4 shows a view of a luminaire with the basic structure Fig. 3 from the ceiling side while
Fig. 5 a room-side view of this lamp without room-side prismatic surface 9 shows and the desired formal division of the light exit surface 13 by the transverse webs 31, 32 can be seen.

In speziellen Anwendungsfällen, insbesondere in entsprechend großen Räumen werden häufig so genannte Lichtbandanordnungen benötigt, und derartige Lichtbandanordnungen können in besonders einfacher und wirksamer Weise ausgehend von der erfindungsgemäßen Leuchte dadurch geschaffen werden, dass modular oder nicht modular aufgebaute Einzelleuchten über beidseitig Fassungshalter für Leuchtstofflampen aufweisende Zwischenträger ohne die sonst übliche Koppeldistanz praktisch nahtlos miteinander verschraubbar sind, wobei diese vorzugsweise mit einer Aufhängung verbundenen Zwischenträger an der raumseitigen Lichtaustrittsfläche Querstege analog den Doppel-Stegteilen der Einzelmodule bilden.In special applications, especially in correspondingly large rooms so-called light band arrangements are often required, and such light band arrangements can be created in a particularly simple and effective manner, starting from the lamp according to the invention that modular or non-modular single luminaires on both sides socket holder for fluorescent lamps having intermediate carrier without the usual coupling distance are virtually seamlessly screwed together, these preferably connected to a suspension intermediate carrier on the room-side light exit surface transverse webs form analogous to the double-web parts of the individual modules.

Auf diese Weise werden formal und strukturell einheitliche und auch großflächige Lichtbänder realisiert, die sich sowohl in lichttechnischer Hinsicht aufgrund der erzielbaren hohen und gleichmäßigen Leuchtdichte als auch in ästhetischer Hinsicht durch ihr extrem flaches Erscheinungsbild auszeichnen.In this way, formally and structurally uniform and large-scale light strips are realized, which are distinguished both in terms of lighting technology due to the achievable high and uniform luminance as well as aesthetically by their extremely flat appearance.
