Abstract

A lighting unit, especially for a lighting system is described and is characterized by a carrier section which has a flattened elongate cross-section which terminates in acute angles at both ends, with all functional elements being concentrated in the central part which always has the largest vertical dimension. Changes of the dimensions lead, as a result of the selected layout to no substantial change in the outer appearance, so that powerful systems can also be realized with the same shape without impairing the external appearance.

Description

SystemleuchteSystem light

Die Erfindung betrifft eine Systemleuchte, insbesondere zur Erzeugung lichtbandartiger Leuchtstrukturen, bestehend aus einem langgestreckten Trägerprofil zur Aufnahme beidendig ge­sockelter Leuchtstofflampen mit zugehörigen Funktionselementen in Form von Vorschaltgeräten, Reflektoren, lichtdurchlässigen Abdeckungen und dergleichen.The invention relates to a system luminaire, in particular for producing light strip-like lighting structures, consisting of an elongated support profile for receiving fluorescent lamps with a base at both ends, with associated functional elements in the form of ballasts, reflectors, translucent covers and the like.

Bekannte Anordnungen dieser Art bestehen aus rohr- oder kasten­förmigen Gehäusen, in denen eine Leuchtstofflampe oder mehrere Leuchtstofflampen zusammen mit den elektrischen Funktionsele­menten untergebracht sind. Um lichtbandartige Strukturen schaf­fen zu können, sind diese Gehäuse entweder direkt oder auch über Verbindungsteile stirnseitig miteinander kuppelbar. Die Rohr- bzw. Kastenform dieser bekannten Anordnungen verhin­dert bei kleinvolumiger Ausgestaltung die Erzielung durchgehen­der Lichtbänder, da zwischen in Längsrichtungen aufeinanderfol­genden Leuchten immer wieder elektrische Funktionselemente, ins­besondere Vorschaltgeräte angeordnet werden müssen, und hat bei großvolumiger Ausgestaltung, wenn in einem Gehäuse mehrere Leuchtstofflampen untergebracht werden müssen, zur Folge, daß sich einerseits in ästhetischer Hinsicht unbefriedigende und häufig plump wirkende Systeme ergeben und andererseits ungün­stige Abstrahlwinkel und ungenügende Wirkungsgrade erhalten werden.Known arrangements of this type consist of tubular or box-shaped housings in which a fluorescent lamp or a plurality of fluorescent lamps are accommodated together with the electrical functional elements. In order to be able to create light band-like structures, these housings can be coupled to one another either directly or via connecting parts on the end face. The tubular or box shape of these known arrangements prevents continuous light strips from being achieved in the case of a small-volume design, since electrical functional elements, in particular ballasts, have to be arranged between successive lights in the longitudinal directions, and has a large-volume design when several fluorescent lamps have to be accommodated in one housing , the result that, on the one hand, aesthetically unsatisfactory and often clumsy-looking systems result and, on the other hand, unfavorable beam angles and insufficient efficiencies are obtained.

Aufgabe der Erfindung ist es, eine Systemleuchte der eingangs angegebenen Art in der Weise auszubilden, daß die Integration der elektrischen Funktionselemente in das Trägerprofil prak­tisch keine Auswirkungen auf das Erscheinungsbild der System­leuchte besitzt und demgemäß Vergrößerungen und Verkleinerungen der Grundform möglich sind, ohne zu einer Veränderung des ästhe­tischen Erscheinungsbildes zu führen. Gleichzeitig soll eine Ver­besserung des Wirkungsgrades, der Abstrahlwinkel und der Abblend­möglichkeiten erreicht und sichergestellt werden, daß durch die Möglichkeit direkter, indirekter und bereichsbezogen konzen­trierter Beleuchtung den unterschiedlichsten lichttechnischen und raumgestaltenden Anforderungen Rechnung getragen werden kann.The object of the invention is to design a system light of the type mentioned in such a way that the integration of the electrical functional elements in the support profile has practically no effect on the appearance of the system light and accordingly enlargements and reductions of the basic shape are possible without changing the to lead aesthetic appearance. At the same time, an improvement in the efficiency, the beam angle and the dimming options should be achieved and it should be ensured that the most varied lighting technology and room design requirements can be taken into account by the possibility of direct, indirect and area-related concentrated lighting.

Gelöst wird diese Aufgabe im wesentlichen dadurch, daß das Trägerprofil einen flachgestreckten, beidseitig spitzwink­lig endenden Querschnitt besitzt und daß in dem die größte Höhenabmessung aufweisenden Mittelteil des Trägerprofils zu­mindest ein kammerartiger Aufnahmebereich für elektrische Funktionselemente oder zumindest eine Leuchtstofflampe aus­gebildet ist.This object is essentially achieved in that the carrier profile has a flat cross-section which ends at both ends at an acute angle and that at least one chamber-like receiving area for electrical functional elements or at least one fluorescent lamp is formed in the central part of the carrier profile which has the greatest height dimension.

Durch die Schaffung und konsequente lichttechnische Nutzung eines derartigen Trägerprofils, das im Querschnitt bevorzugt die Form einer mittensymmetrischen Konvexlinse besitzt, wird es im Gegensatz zu Systemen anderer Querschnittsform, insbe­sondere Systemen mit runder oder rechteckiger Querschnitts­form, möglich, die beispielsweise für eine Leuchtstofflampe bestimmte Grundstruktur zur Aufnahme mehrerer Leuchtstofflam­pen ohne proportionale oder annähernd proportionale Volumener­höhung zu vergrößern. Unabhängig von der jeweiligen Lichtlei­stung und Größe der Leuchte bleibt damit das äußere Erschei­nungsbild der Systemleuchte praktisch unverändert, was ins­besondere eine Folge davon ist, daß durch die gewählte Struk­tur im Mittelteil der Leuchte ein zur Aufnahme von Funktions­elementen optimal geeigneter Raum zur Verfügung steht, dessen Aufnahmevolumen sich bereits bei geringer Verkleinerung oder Ver­größerung der Außenkontur des Trägerprofils stark ändert. Dies wirkt sich besonders bei einer Vergrößerung der Außenabmessungen günstig aus, da schon vergleichsweise geringe Vergrößerungen der Außenabmessungen im Mittelbereich soviel zusätzlichen Raum schaffen, daß ergänzend erforderliche elektrische Funktions­elemente problemfrei untergebracht werden können.The creation and consequent use of such a support profile in terms of lighting technology, which preferably has the shape of a center-symmetrical convex lens in cross-section, makes it possible, in contrast to systems of other cross-sectional shape, in particular systems with a round or rectangular cross-sectional shape, to accommodate a basic structure intended for a fluorescent lamp, for example to enlarge several fluorescent lamps without proportional or nearly proportional increase in volume. Regardless of the respective light output and size of the luminaire, the external appearance of the system luminaire remains practically unchanged, which is a result in particular of the fact that the structure selected in the middle part of the luminaire provides a space that is optimally suitable for accommodating functional elements, the volume of which can be accommodated changes even with a small reduction or enlargement of the outer contour of the carrier profile. This has a particularly favorable effect when the outer dimensions are enlarged, since even comparatively small enlargements of the outer dimensions in the central region create so much additional space that electrical functional elements which are additionally required can be accommodated without problems.

Die schematische Querschnittsansicht der Fig. 1 zeigt ein ins­besondere im Stranggußverfahren hergestelltes Trägerprofil 1, das die Form einer mittensymmetrischen, relativ flachen Konvex­linse besitzt. Begrenzt wird dieses Trägerprofil 1 praktisch nur von zwei gekrümmten Flächen in Form eines oberen Schalen­teils 4 und eines unteren Schalenteils 3, wobei in diesem Aus­führungsbeispiel das obere Schalenteil 4 ganzflächig geschlos­sen ist, während das untere Schalenteil 3 Ausnehmungen zur Auf­nahme lichtdurchlässiger Abdeckungen 12 besitzt.The schematic cross-sectional view of FIG. 1 shows a carrier profile 1 which is produced in particular by the continuous casting process and which has the shape of a center-symmetrical, relatively flat convex lens. This support profile 1 is practically only limited by two curved surfaces in the form of an upper shell part 4 and a lower shell part 3, in this embodiment the upper shell part 4 being closed over the entire surface, while the lower shell part 3 has recesses for receiving translucent covers 12.

Durch die beiden Schalenteile 3, 4 miteinander verbindende vertikale Stege 5 wird im Trägerprofil 1 ein Mittelteil 2 ab­ gegrenzt, das einen Aufnahmebereich 6 für elektrische Funk­tionselemente, insbesondere ein Vorschaltgerät 7 und im dar­gestellten Falle einer Stromschiene 8 bildet.Through the two shell parts 3, 4 connecting vertical webs 5, a central part 2 is in the carrier profile 1 limited, which forms a receiving area 6 for electrical functional elements, in particular a ballast 7 and in the case shown a busbar 8.

Beiderseits des Mittelteils 2 befinden sich Profilkammern 9, 10, in denen Leuchtstoffröhren 11 angeordnet sind. Die zuge­hörigen Lampenfassungen sind an den stirnseitigen Endwänden des Trägerprofils angebracht.On both sides of the middle part 2 there are profile chambers 9, 10, in which fluorescent tubes 11 are arranged. The associated lamp holders are attached to the front end walls of the support profile.

Die flachen, seitlichen Bereiche der Profilkammern 9, 10 sind als Staukammern 13 für elektrische Kabel 15 und Leitungen aus­gebildet. Dazu ist es lediglich erforderlich, an das untere Schalenteil einen etwa vertikalen, gleichzeitig zur Halterung der lichtdurchlässigen Abdeckungen 12 benutzbaren Steg 19 auszu­bilden, der sich nur über einen Teil der Höhe der Profilkammer erstreckt, so daß die jeweilige Staukammer 13 über einen Schlitz zum Einlegen der Leitungen zugänglich ist.The flat, lateral areas of the profile chambers 9, 10 are designed as storage chambers 13 for electrical cables 15 and lines. To do this, it is only necessary to form an approximately vertical web 19 on the lower shell part, which can also be used to hold the translucent covers 12 and which extends only over part of the height of the profile chamber, so that the respective storage chamber 13 has a slot for inserting the Lines is accessible.

Zur Erzeugung eines schmalen, seitlichen Lichtbandes sind die Eckteile 14 des Trägerprofils 1 mit einem Aufnahmeschlitz für ein Licht konzentrierendes Material ausgebildet, und diese Schlitze stehen über Öffnungen mit den Profilkammern 9, 10 in Verbindung, so daß durch die Öffnungen Licht treten kann und damit diese schmalen Lichtbänder wirksam werden können.To produce a narrow, lateral light band, the corner parts 14 of the carrier profile 1 are formed with a receiving slot for a light-concentrating material, and these slots are connected via openings to the profile chambers 9, 10 so that light can pass through the openings and thus these narrow strips of light can take effect.

Während sich die Profilkammern 9, 10 aufgrund ihrer Breite hinsichtlich des erwünschten Abstrahlwinkels und auch des Wir­kungsgrades günstig auswirken, ermöglicht es die Höhe des Mit­telteils 2, problemfrei alle elektrischen Funktionselemente, insbesondere Vorschaltgeräte und auch zusätzlich vorgesehene Stromschienen problemfrei unterzubringen. Dabei gewährleistet die Ausgestaltung des Trägerprofils eine hohe mechanische Fe­stigkeit als Folge der das Mittelteil 2 bildenden Kastenkon­struktion.While the profile chambers 9, 10 have a favorable effect due to their width with regard to the desired radiation angle and also the efficiency, the height of the central part 2 enables all electrical functional elements, in particular ballasts and also additionally provided busbars, to be accommodated without problems. The design of the support profile ensures high mechanical strength as a result of the box construction forming the middle part 2.

Fig. 2 zeigt eine Ausführungsvariante, die zusätzlich zu der bei Fig. 1 gegebenen direkten Beleuchtung eine indirekte Be­leuchtung mittels einer weiteren, im Mittelteil 2 angeordneten Leuchtstoffröhre 11 ermöglicht. Dabei ist im Mittelteil 2 wei­terhin ein Vorschaltgerät 7 angeordnet. Es sind jedoch die Ver­tikalstege 5 nach oben divergierend ausgebildet, so daß sich ein günstiger Abstrahlwinkel über die lichtdurchlässige Ab­deckung 12 erzielen läßt. Trotz dieser zusätzlichen Möglich­keit der gleichzeitigen Schaffung einer indirekten Beleuchtung werden die Außenabmessungen des Trägerprofils nur unwesentlich verändert.FIG. 2 shows an embodiment variant which, in addition to the direct lighting given in FIG. 1, enables indirect lighting by means of a further fluorescent tube 11 arranged in the middle part 2. A ballast 7 is also arranged in the middle part 2. However, the vertical webs 5 are designed to diverge upwards, so that a favorable radiation angle can be achieved via the translucent cover 12. Despite this additional possibility of creating indirect lighting at the same time, the outer dimensions of the support profile are changed only insignificantly.

Fig. 3 zeigt eine Ausführungsform, bei der unter Beibehaltung der Breitenabmessung die Höhenabmessung vergrößert und dadurch wiederum unter Beibehaltung der Grundform einerseits Aufnahme­räume für Reflektoren 17 zur Erzeugung einer gewünschten direk­ten Beleuchtung geschaffen werden und andererseits ein speziel­ler Aufnahmeraum 18 für eine Leuchtstoffröhre 11 zur Erzielung einer indirekten Beleuchtung erhalten wird.Fig. 3 shows an embodiment in which while maintaining the width dimension increases the height dimension and thereby in turn while maintaining the basic shape on the one hand receiving spaces for reflectors 17 to create a desired direct lighting and on the other hand a special receiving space 18 for a fluorescent tube 11 to achieve an indirect Lighting is obtained.

Das Mittelteil 2 umfaßt hierbei einen Aufnahmebereich 6 für das Vorschaltgerät 7 und gegebenenfalls weitere elektrische Funktionselemente sowie einen darüberliegenden, divergierenden Aufnahmeraum für die Leuchtstoffröhre 11.The middle part 2 in this case comprises a receiving area 6 for the ballast 7 and, if appropriate, further electrical functional elements and an overlying, diverging receiving space for the fluorescent tube 11.

Eine vergleichsweise geringe Erhöhung des Mittelteils des Trä­gerprofils führt dazu, daß ohne Beeinträchtigung der Unter­bringungsmöglichkeiten für die elektrischen Funktionselemente ein zusätzlicher Aufnahme- und damit Abstrahlraum 18 zur Ver­fügung steht und außerdem eine vergleichsweise große Freiheit hinsichtlich der Ausgestaltung, d.h. des Verlaufs und der Krüm­mung der Reflektoren 17 für die direkte Beleuchtung erhalten wird.A comparatively small increase in the central part of the support profile means that an additional receiving and thus radiation space 18 is available without impairing the accommodation options for the electrical functional elements and, moreover, a comparatively great freedom with regard to the design, i.e. the course and curvature of the reflectors 17 for direct lighting is obtained.

Die Variante nach Fig. 4 macht deutlich, daß die durch spe­zielle Reflektorgestaltung erzielbare großfläche Direktbeleuch­tung ohne Schwierigkeiten auch mit einer beispielsweise punkt­ förmigen Beleuchtung kombiniert werden kann, indem in das Trägerprofil eine im Mittelteil fixierte Stromschiene 8 in­tegriert wird, die zur Aufnahme herkömmlicher Strahler geeig­net ist. Auch hier sind wiederum alle elektrischen Funktions­elemente im raummäßig günstigen Mittelteil konzentriert, das zur Aufnahme dieser teilweise schweren Elemente aufgrund sei­ner durch die Kammerstruktur bedingten mechanischen Stabilität auch besonders geeignet ist.The variant according to FIG. 4 makes it clear that the large area direct lighting which can be achieved by means of a special reflector design can be achieved without difficulty even with a point, for example Shaped lighting can be combined by integrating a busbar 8 fixed in the central part into the support profile, which is suitable for receiving conventional spotlights. Again, all the electrical functional elements are concentrated in the spatially favorable central part, which is also particularly suitable for accommodating these sometimes heavy elements due to its mechanical stability due to the chamber structure.

Die Ausführungsform nach Fig. 5 verdeutlicht, daß auch im Falle einer Kombination von direkter, indirekter und beispiels­weise punktförmiger Beleuchtung und der dafür erforderlichen elektrischen Funktionselemente der innerhalb des Trägerprofils zur Verfügung stehende Raum in optimaler Weise genutzt werden kann und gleichzeitig durch entsprechende Profilgestaltung die notwendige mechanische Stabilität gegeben ist. Obwohl bei die­ser Ausführungsform nach Fig. 7 im Mittelteil Raum für einan­der gegenüberliegend angeordnete Vorschaltgeräte bereitgestellt und an der Unterseite eine Stromschiene 8 integriert ist sowie Aufnahmebereiche für Kabel 15 und Leitungen zur Verfügung stehen, ergibt sich keine Veränderung der Grundform des Trä­gerprofils. Eine Vergrößerung der Trägerprofilhöhe führt dem­gemäß zwar zu einer sofort merkbaren Volumenerhöhung im zur Aufnahme der Funktionselemente bestimmten Mittelteil, verändert aber die Gesamtstruktur und damit das Erscheinungsbild der System­leuchte nicht in merkbarer Weise.The embodiment of FIG. 5 illustrates that even in the case of a combination of direct, indirect and, for example, point-shaped lighting and the electrical functional elements required for this, the space available within the support profile can be used in an optimal manner and, at the same time, the necessary mechanical design can be achieved by appropriate profile design Stability is given. Although in this embodiment according to FIG. 7, space is provided in the central part for ballasts arranged opposite one another and a busbar 8 is integrated on the underside, and receiving areas for cables 15 and lines are available, there is no change in the basic shape of the carrier profile. An increase in the height of the support profile accordingly leads to an immediately noticeable increase in volume in the middle part intended to accommodate the functional elements, but does not noticeably change the overall structure and thus the appearance of the system light.

Fig. 6 zeigt eine Möglichkeit der Reihenschaltung mehrerer Systemleuchten durch Verbindung über rohrförmige Elemente 21. Dazu sind im Trägerprofil, insbesondere an dessen Oberseite, Kupplungsaufnahmen 20 für Rohrelemente vorgesehen, wodurch sich einfache Steckkupplungsmöglichkeiten ergeben. Im Bereich der Profilteile können diese Rohrelemente auch fest integriert sein, so daß sich eine durchgehende Rohrstruktur ergibt, die gleich­zeitig so ausgestaltet sein kann, daß - wie in Fig. 6 angedeu­tet - Teilbereiche der Rohrwandung lichtdurchlässig ausgebildet sind und im Verbindungsrohr eine Leuchtstoffröhre 11 angeord­net ist. Auf diese Weise wird die Möglichkeit der Erzielung einer indirekten Beleuchtung durch Ausnutzung der Verbindungs­elemente erhalten, was wiederum zu einer günstigen Gesamtstruk­tur von vergleichsweise geringer Höhe des Trägerprofils führt.6 shows a possibility of connecting a plurality of system lights in series by connection via tubular elements 21. For this purpose, coupling receptacles 20 for tubular elements are provided in the carrier profile, in particular on its upper side, which results in simple plug-in coupling options. In the area of the profile parts, these tube elements can also be firmly integrated, so that there is a continuous tube structure which can at the same time be designed such that — as indicated in FIG. 6 — partial areas of the tube wall are made translucent are and a fluorescent tube 11 is arranged in the connecting tube. In this way, the possibility of achieving indirect lighting is obtained by utilizing the connecting elements, which in turn leads to a favorable overall structure with a comparatively low height of the support profile.

Fig. 7 zeigt eine Ausführungsform, bei der an der Unterseite des Trägerprofils stirnseitig gehaltert ein Rohrelement 21 vor­gesehen ist, das auch mit weiterführenden Rohren kuppelbar sein kann, und in dem eine Leuchtstoffröhre 11 in der Weise angeordnet ist, daß nach unten eine Abschirmung gegeben und eine Abstrah­lung über die Reflexion an dem oberen Schalenteil 4 erreicht ist.Fig. 7 shows an embodiment in which a tubular element 21 is provided on the underside of the support profile, which can also be coupled with further tubes, and in which a fluorescent tube 11 is arranged in such a way that a shield is provided at the bottom and radiation via the reflection on the upper shell part 4 is achieved.

Nach einer weiteren Besonderheit der Erfindung können Mittel­teile und Seitenteile separat ausgebildet und miteinander kuppel­bar, insbesondere verklipsbar ausgestaltet werden, so daß eine Baukastenanordnung erhalten wird, die den Aufbau ein- oder zwei­teiliger Leuchten ermöglicht.According to a further special feature of the invention, middle parts and side parts can be formed separately and can be coupled, in particular clipped, so that a modular arrangement is obtained which enables the construction of one- or two-part lamps.

Fig. 7 zeigt eine bevorzugte Ausführungsvariante, bei der das die Form einer Konvexlinse besitzende Trägerprofil 1 aus zwei identisch ausgebildeten seitlichen Profilteilen 24 und einem Mittelbereich besteht, wobei der Mittelbereich 26 zur Aufnahme einer oder mehrerer Leuchtstoffröhren 11 und entsprechender Reflektoren 17 dient. Die seitlichen Profilteile 24 sind in der Weise mit durchgehenden Stegen, Ausnehmungen und Hinter­schneidungen versehen, daß sich einfache Kopplungsverbindungen mit dem Mittelbereich 26 zugeordneten lichtdurchlässigen oder lichtundurchlässigen Abdeckungen 23, Blendrastern oder Streu­scheiben 22 erzielen lassen. In den seitlichen Profilteilen sind ferner Kammern zur Aufnahme von Funktionseinheiten 25 aus­gebildet.7 shows a preferred embodiment variant, in which the carrier profile 1, which has the shape of a convex lens, consists of two identically designed lateral profile parts 24 and a central region, the central region 26 being used to receive one or more fluorescent tubes 11 and corresponding reflectors 17. The lateral profile parts 24 are provided with continuous webs, recesses and undercuts in such a way that simple coupling connections can be achieved with the translucent or opaque covers 23, blind grids or diffusers 22 assigned to the central region 26. In the lateral profile parts, chambers for receiving functional units 25 are also formed.

Während die seitlichen Profilteile zusammen mit ihrer gegen­seitigen Verbindung eine gleichbleibende Grundstruktur bei die­ser Ausführungsform darstellen, kann der Mittelbereich 26 in unterschiedlicher Weise mit Reflektoren, Abdeckungen und Leucht­stoffröhren bestückt werden, so daß sich unterschiedliche Ab­strahlcharakteristiken einseitig oder beidseitig ergeben und somit den in der Praxis auftretenden Forderungen nach Art eines Baukastensystems auf besonders wirtschaftliche Weise Rechnung getragen werden kann.While the side profile parts together with their mutual connection represent a constant basic structure in this embodiment, the central region 26 can be equipped in different ways with reflectors, covers and fluorescent tubes, so that different radiation characteristics result on one or both sides and thus meet the requirements that arise in practice can be taken into account in a particularly economical manner in the manner of a modular system.

Die beispielsweise geschilderten Ausführungsvarianten der Erfin­dung machen deutlich, daß die spezielle Querschnittsform des Trägerprofils eine hohe Variabilität hinsichtlich der Abstrahl­winkel und auch der Abblendmöglichkeiten bei stets vorhandenem hohem Wirkungsgrad ermöglicht. Diese vorteilhaften Eigenschaf­ten sind gepaart mit hoher Stabilität und optimaler Gewichts­verteilung, wobei für alle Ausführungsvarianten gilt, daß trotz unterschiedlicher Höhenabmessungen das äußere Erscheinungsbild praktisch unverändert bleibt.The exemplary embodiments of the invention described, for example, make it clear that the special cross-sectional shape of the carrier profile enables a high degree of variability with regard to the radiation angle and also the dimming options with a high level of efficiency which is always present. These advantageous properties are paired with high stability and optimal weight distribution, whereby it applies to all design variants that, despite different height dimensions, the external appearance remains practically unchanged.
