Description

Die vorliegende Erfindung betrifft ein Lichtbandsystem mit einem länglichen Trägerelement, an dem Leuchteneinheiten befestigt sind. Das Lichtbandsystem ist dabei derart ausgestaltet, dass das nachträgliche Anbringen von transparenten Abdeckungen für die Leuchteneinheiten ermöglicht ist.The present invention relates to a lighting system with an elongate support member to which lighting units are attached. The light band system is designed such that the subsequent attachment of transparent covers for the lamp units is made possible.

Lichtbandsysteme sind in unterschiedlichen Formen bekannt. Sie finden vielfach Verwendung, da sie gegenüber fest installierten oder eingebauten Leuchten eine hohe Flexibilität bei der individuellen Planung von Beleuchtungsstrukturen bieten. Da derartige Systeme aus einzelnen Elementen bestehen, die nach dem Baukasten-Prinzip zusammengesetzt werden, kann die gesamte Anordnung in einfacher Weise an die zu beleuchtenden Räumlichkeiten angepasst werden.Lichtbandsysteme are known in different forms. They are widely used, as they offer a high degree of flexibility in the individual planning of lighting structures compared to fixed or built-in luminaires. Since such systems consist of individual elements that are assembled according to the modular principle, the entire arrangement can be easily adapted to the premises to be illuminated.

Ein bekanntes Lichtbandsystem, welches bspw. in der DE 100 25 647 A1 der Anmelderin beschrieben ist, ist in Fig. 1 dargestellt. Das Grundgerüst des bekannten Lichtbandsystems 100 wird durch eine längliche Tragschiene 10 gebildet, welche durch ein zur Unterseite hin offenes, U-förmiges Profilelement gebildet ist. Diese Tragschiene 10 kann entweder unmittelbar an einer Decke oder abgehängt befestigt werden und dient der Halterung mehrerer Leuchteneinheiten, wobei in Fig. 1 eine einzelne Leuchteneinheit dargestellt ist, welche mit dem Bezugszeichen 30 versehen ist. In diesem Zusammenhang ist darauf hinzuweisen, dass Fig. 1 lediglich einen kurzen Abschnitt des Lichtbandsystems 100 zeigt. Tatsächlich ist die Tragschiene 10 deutlich länger als die daran befestigte Leuchteneinheit 30, so dass in der Regel mehrere Leuchteneinheiten 30 hintereinander an der Tragschiene 10 befestigt sind.A well-known lighting system, which, for example, in the DE 100 25 647 A1 the applicant is described in Fig. 1 shown. The basic structure of the known lighting strip system 100 is formed by an elongate support rail 10, which is formed by a U-shaped profile element which is open toward the underside. This support rail 10 can either be attached directly to a ceiling or suspended and serves to hold several lighting units, wherein in Fig. 1 a single lamp unit is shown, which is provided with the reference numeral 30. In this context, it should be noted that Fig. 1 only shows a short section of the lighting system 100. In fact, the support rail 10 is significantly longer than the attached lighting unit 30, so that in general a plurality of lamp units 30 are mounted one behind the other on the support rail 10.

Die Leuchteneinheit 30 wiederum besteht zunächst aus einer länglichen Abdeckschiene 31, welche von der Unterseite her an die Tragschiene 10 angesetzt und befestigt wird. Mit Hilfe von Betätigungselementen, welche über Öffnungen 35 in der Abdeckschiene 31 zugängig sind, kann dabei sowohl eine mechanische Befestigung an der Tragschiene 10 als auch eine elektrische Kontaktierung innerhalb der Tragschiene 10 verlaufender Stromleitungen erfolgen. Das dargestellte Lichtbandsystem 100 zeichnet sich dabei dadurch aus, dass eine freie Anordnung der Leuchteneinheiten 30 an der Tragschiene 10 ermöglicht ist, was die Flexibilität des Lichtbandsystems 100 zusätzlich erhöht. Es sind allerdings auch Lichtbandsysteme bekannt, bei denen die Leuchteneinheiten lediglich an fest vorgegebenen Positionen angeordnet werden können.The lamp unit 30, in turn, initially consists of an elongate cover rail 31, which is attached and secured from the bottom to the support rail 10. With the help of actuators, which are accessible via openings 35 in the covering rail 31, can be both a mechanical attachment to the support rail 10 and an electrical contact within the support rail 10 extending power lines take place. The light band system 100 shown here is characterized in that a free arrangement of the lamp units 30 is made possible on the support rail 10, which additionally increases the flexibility of the light band system 100. However, there are also known light band systems in which the lighting units can be arranged only at fixed predetermined positions.

Die Leuchteneinheit 30 weist weiterhin an den beiden Stirnseiten Halteelemente 32 auf, welche der Halterung von Lampenfassungen 33 dienen. In diese Fassungen 33 ist im dargestellten Ausführungsbeispiel eine längliche Lichtquelle 34 in Form einer Leuchtstofflampe eingesetzt. Die Stromversorgung der Lampe 34 erfolgt über Lampenbetriebsmittel, welche an der Oberseite der Abdeckschiene 31 angeordnet und dementsprechend nach Montage der Leuchteneinheit 30 in dem Aufnahmeraum 11 der Tragschiene 10 angeordnet sind.The lamp unit 30 further has on the two end faces holding elements 32 which serve to hold lamp sockets 33. In these versions 33, an elongated light source 34 is used in the form of a fluorescent lamp in the illustrated embodiment. The power supply of the lamp 34 via lamp operating means, which are arranged on the top of the cover rail 31 and accordingly arranged after mounting the lamp unit 30 in the receiving space 11 of the support rail 10.

Die an der Tragschiene befestigen Leuchteneinheiten können unterschiedlich ausgestaltet sein und insbesondere auch Reflektoren oder andere optische Elemente zur Beeinflussung der Lichtabgabe aufweisen. Nicht selten werden allerdings auch Leuchteneinheiten in der in Fig. 1 dargestellten Form verwendet, welche lediglich die Lichtquelle aufweisen, nicht jedoch weitere Elemente, welche die Lichtquelle umschließen. Dabei werden die Leuchteneinheiten üblicherweise unmittelbar hintereinander an der Tragschiene montiert, so dass keine Freiräume zwischen diesen verbleiben.The fastening to the mounting rail lamp units can be designed differently and in particular also have reflectors or other optical elements to influence the light output. Not infrequently, however, also lighting units in the in Fig. 1 used form, which have only the light source, but not other elements which surround the light source. The lighting units are usually mounted directly behind one another on the mounting rail, so that no free space between them.

Es hat sich nunmehr herausgestellt, dass oftmals das Bedürfnis besteht, bei derartigen Lichtbändern, bei denen derart einfache Leuchteneinheiten verwendet werden, die Lichtquellen nachträglich mit einer transparenten, bspw. quaderförmigen Abdeckung umgeben zu können. Derartige Abdeckungen ermöglichen einerseits eine Beeinflussung des von der Lichtquelle abgegebenen Lichts, auf der anderen Seite werden sie vielfach aus optischen Gründen gewünscht. Hierbei ergibt sich dann allerdings das Problem, dass sich derartige transparente Abdeckungen aufgrund des hierbei verwendeten Materials infolge von Temperaturschwankungen verhältnismäßig stark ausdehnen bzw. zusammenziehen, was während des Betriebs zu nicht unbeträchtlichen Problemen führen kann.It has now been found that there is often the need to be able to surround the light sources with a transparent, for example. Cuboid cover in such light bands, in which such simple lighting units are used. Such covers allow on the one hand to influence the light emitted by the light source, on the other hand, they are often desired for optical reasons. In this case, however, there is the problem that such transparent covers due to the material used here as a result of temperature fluctuations relatively greatly expand or contract, which can lead to not inconsiderable problems during operation.

Der vorliegenden Erfindung liegt dementsprechend die Aufgabe zugrunde, die Möglichkeit zu eröffnen, bei einem Lichtbandsystem der oben beschriebenen Art den Leuchteneinheiten nachträglich eine transparente bzw. opale Abdeckung zuzuordnen.Accordingly, it is the object of the present invention to provide the possibility of subsequently assigning a transparent or opal cover to the lamp units in a continuous-row lighting system of the type described above.

Die Aufgabe wird durch ein Lichtbandsystem, welches die Merkmale des Anspruchs 1 aufweist, gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a lighting strip system, which has the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Lösung beruht auf der Idee, Abdeckungen zu verwenden, die ein oder mehrere Leuchteneinheiten, bevorzugt maximal drei, gleichzeitig überdecken und lösbar an der Tragschiene oder der Leuchteneinheit befestigt werden können. Dabei sind die Abdeckungen derart ausgestaltet, dass sie sich ungehindert in Längsrichtung ausdehnen können, was dadurch erzielt wird, dass diese ein im Wesentlichen U-förmig ausgebildetes und an seinen Stirnseiten offenes Profilelement aufweisen.The solution according to the invention is based on the idea of using covers which simultaneously cover one or more lighting units, preferably a maximum of three, and which can be detachably fastened to the mounting rail or the lighting unit. In this case, the covers are designed such that they can expand unhindered in the longitudinal direction, which is achieved in that they have a substantially U-shaped and open at its end faces profile element.

Dementsprechend wird erfindungsgemäß ein Lichtbandsystem mit einem länglichen Trägerelement vorgeschlagen, an dem mindestens eine Leuchteneinheit mit einer länglichen Lichtquelle lösbar befestigt ist, wobei der Leuchteneinheit eine die Lichtquelle umgebende opale Abdeckung zugeordnet ist, welche ein zumindest teilweise transparentes Profilelement aufweist, das lösbar an dem Trägerelement oder der Leuchteneinheit befestigt ist, im Wesentlichen U-förmig und an seinen Stirnseiten offen ist und dessen Länge in etwa der Länge der Leuchteneinheit oder einem ganzzahligen Vielfachen der Länge der Leuchteneinheit entspricht.Accordingly, the invention proposes a continuous-row lighting system with an elongated support element, to which at least one lamp unit is detachably attached with an elongated light source, wherein the lamp unit is associated with an opal cover surrounding the light source, which has an at least partially transparent profile element which is releasably attached to the support element or the lamp unit is fixed, is substantially U-shaped and open at its ends and whose length corresponds approximately to the length of the lamp unit or an integral multiple of the length of the lamp unit.

Vorzugsweise ist dabei vorgesehen, dass das Profilelement eine Länge aufweist, die geringfügig kürzer ist als die Länge der Leuchteneinheit bzw. des ganzzahligen Vielfachen der Leuchteneinheit. In Fällen, in denen mehrere Leuchteneinheiten unmittelbar aufeinanderfolgend an der Tragschiene montiert sind, ist dann vorgesehen, dass die Abdeckungen nicht direkt aneinander stoßend sondern mit einem Abstand von etwa 5mm montiert werden. Diese Freiräume ermöglichen selbst im Falle hoher Temperaturschwankungen ein ungehindertes Ausdehnen der Abdeckungen. Vorzugsweise ist dabei vorgesehen, dass das Profilelement mit dem Trägerelement oder der bzw. den Leuchteneinheiten bzw. Teilen davon verrastbar ist.Preferably, it is provided that the profile element has a length which is slightly shorter than the length of the lamp unit or the integer multiple of the lamp unit. In cases where several lamp units are mounted directly successively on the mounting rail, it is then provided that the covers are not directly abutting but mounted with a distance of about 5mm. These open spaces allow even in case of high Temperature fluctuations unimpeded expansion of the covers. Preferably, it is provided that the profile element with the carrier element or the or the lighting units or parts thereof can be latched.

Eine weitere Problematik bei Verwendung derartiger transparenter Abdeckungen besteht darin, dass Insekten, die ins Innere der Abdeckung gelangen und verenden, von außen als dunkle, unschöne Flecken sichtbar sind. Um derartige Effekte bei dem Lichtbandsystem gemäß der vorliegenden Erfindung zu vermeiden, ist gemäß einem besonders bevorzugten Ausführungsbeispiel vorgesehen, dass die nachträglich anbringbare Abdeckung zuzüglich zu dem Profilelement davon getrennte Stirnteile aufweist, welche an den Stirnseiten der Leuchteneinheiten befestigbar sind. Hierbei ist insbesondere vorzugsweise vorgesehen, dass die Stirnteile auf Fassungshalter der Leuchteneinheiten aufsetzbar bzw. aufschnappbar sind. Diese Stirnteile werden dann von der Abdeckung übergriffen und zwar derart, dass sie die temperaturbedingte Längenänderung der Abdeckung nicht beeinträchtigen. Die Stirnteile sind vorzugsweise ebenfalls lichtdurchlässig bzw. opal ausgeführt, was einerseits den Vorteil mit sich bringt, dass sie sich auf der Abdeckung nicht abbilden. Ferner wird der gleichmäßige opale Eindruck der gesamten Anordnung nicht gestört.Another problem with the use of such transparent covers is that insects that reach the inside of the cover and end up, are visible from the outside as a dark, unsightly stains. To avoid such effects in the lighting system according to the present invention, it is provided according to a particularly preferred embodiment that the subsequently attachable cover in addition to the profile element thereof has separate end portions, which are attachable to the end faces of the lamp units. In this case, it is particularly preferably provided that the end parts can be placed or snapped onto the holder holders of the lamp units. These end parts are then overlapped by the cover in such a way that they do not affect the temperature-induced change in length of the cover. The end parts are preferably also translucent or opal, which on the one hand brings with it the advantage that they do not map on the cover. Furthermore, the uniform opal impression of the entire arrangement is not disturbed.

Die Anordnung der zuvor beschriebenen Stirnteile erfolgt selbstverständlich lediglich an den beiden Enden der gesamten Anordnung. Im Stoßbereich zwischen zwei benachbarten Profilelementen hingegen ist ein Einsatz dieser Stirnteile nicht sinnvoll, sodass hier ein Luftspalt von etwa 5mm verbleiben würde, der die Ausdehnung der Profilelemente bei Temperaturschwankungen ermöglicht. Da aus optischen Gründen allerdings auch derartige Luftspalte vermieden werden sollten, kann gemäß einer besonders bevorzugten Weiterbildung der Erfindung zusätzlich ein spezielles Verbindungselement eingesetzt werden. Dieses ist derart gestaltet, dass es ebenso wie die Profilelemente lösbar an dem Trägerelement oder der Leuchteneinheit befestigt werden kann. Es befindet sich hierbei zwischen den einzelnen Optiken bzw. Profilelementen und wird von diesen übergriffen. Durch die Anordnung des Verbindungselements innerhalb der Profilelemente wird weiterhin die Längenausdehnung der Profilelemente nicht beeinträchtigt. Gleichzeitig folgt allerdings von der Innenseite her eine Abdeckung des Luftspalts, was einerseits optische Vorteile mit sich bringt, andererseits wiederum verhindert, dass von Außen her Insekten oder dergleichen in das Innere der Anordnung gelangen können.The arrangement of the end portions described above is of course only at the two ends of the entire arrangement. In the joint area between two adjacent profile elements, however, use of these end pieces is not meaningful, so that here an air gap of about 5mm would remain, which allows the expansion of the profile elements with temperature fluctuations. Since, for optical reasons, however, such air gaps should be avoided, according to a particularly preferred embodiment of the invention, in addition a special connection element can be used. This is designed such that it can be releasably attached to the support element or the lamp unit as well as the profile elements. It is located here between the individual optics or profile elements and is overlapped by these. The arrangement of the connecting element within the profile elements, the length extension of the profile elements is still not affected. At the same time, however, follows from the inside a cover of the air gap, on the one hand on the other hand, prevents external insects or the like from getting into the interior of the arrangement.

Letztendlich bietet die vorliegende Erfindung die Möglichkeit, bestehende Lichtbandsysteme in einfacher Weise mit transparenten Abdeckungen nachzurüsten, um den optischen Gesamteindruck des Lichtbandsystems zu verbessern.Ultimately, the present invention provides the ability to retrofit existing trunking systems in a simple manner with transparent covers to improve the overall appearance of the lighting system.

Das in Fig. 1 dargestellte Lichtbandsystem 100 wurde bereits eingangs erläutert, wobei ergänzend hierzu auf die DE 100 25 647 A1 verwiesen wird, in der dieses Lichtbandsystem detailliert beschrieben ist. Die vorliegende Erfindung stellt nun eine Ergänzung zu diesem Lichtbandsystem 100 dar, welche es ermöglicht, die Leuchteneinheiten 30 nachträglich mit einer transparenten bzw. opalen Abdeckung zu umgeben, wie dies in Fig. 2 gezeigt ist. Die Abdeckung 50 soll hierbei die Lichtquellen der Leuchteneinheit 30 bzw. mehrerer Leuchteneinheiten quaderförmig umschließen, wobei selbstverständlich auch andere Formen für die Abdeckung 50 denkbar wären.This in Fig. 1 shown light band system 100 has already been explained in the introduction, in addition to this on the DE 100 25 647 A1 in which this lighting system is described in detail. The present invention is now an addition to this lighting system 100, which makes it possible to subsequently surround the lighting units 30 with a transparent or opal cover, as shown in FIG Fig. 2 is shown. In this case, the cover 50 is intended to enclose the light sources of the lamp unit 30 or of a plurality of lamp units in the shape of a cuboid, it being understood that other shapes for the cover 50 would also be conceivable.

Aufgrund des für derartige Abdeckungen üblicherweise verwendeten KunststoffMaterials besteht allerdings das Problem, dass infolge von Temperaturschwankungen sich die Abdeckung 50 im Vergleich zu der Tragschiene 10, welche üblicherweise aus Metall gefertigt ist, unterschiedlich stark ausdehnt. Diesem Problem wird mit einer speziellen Ausgestaltung der Abdeckung 50 Rechnung getragen, was nachfolgend näher erläutert werden soll.Due to the plastic material commonly used for such covers, however, there is the problem that as a result of temperature fluctuations, the cover 50 expands to different extents compared to the support rail 10, which is usually made of metal. This problem is taken into account with a special embodiment of the cover 50, which will be explained in more detail below.

Die Besonderheit der Abdeckung 50 besteht in der Verwendung unterschiedlicher Bauteile. So ist die Abdeckung 50 einerseits aus einem im Wesentlichen U-förmigen Profilelement 51 sowie andererseits aus zwei Stirnteilen 60 gebildet, deren Ausgestaltung nachfolgend anhand der Fig. 3 bis 11 näher erläutert werden soll.The peculiarity of the cover 50 is the use of different components. Thus, the cover 50 is formed on the one hand from a substantially U-shaped profile element 51 and on the other hand from two end portions 60, whose configuration is described below with reference to Fig. 3 to 11 will be explained in more detail.

Die Fig. 3 bis 5 zeigen dabei zunächst die Ausgestaltung des U-förmigen Profilelements 51, welches von der Unterseite her an dem Lichtbandsystem 100 befestigt werden kann. Im dargestellten Ausführungsbeispiel ist dabei die Bodenseite 52 des Profilelements 51 ebenso wie die beiden Seitenwände 53 transparent ausgebildet, so dass über sämtliche Flächen hinweg eine Lichtabgabe erfolgen kann. Selbstverständlich wäre es allerdings auch möglich, die Seitenwände 53 lichtundurchlässig zu gestalten, falls eine Lichtabgabe lediglich zur Unterseite hin gewünscht ist. Auch die Verwendung von Farbfiltern für die verschiedenen Flächen wäre denkbar, um die Farbe des über die Abdeckung 51 abgegebenen Lichts in gewünschter Weise zu beeinflussen.The Fig. 3 to 5 initially show the configuration of the U-shaped profile element 51, which can be attached from the bottom to the lighting system 100. In the illustrated embodiment, while the bottom side 52 of the profile element 51 as well as the two side walls 53 is formed transparent, so that over all surfaces across a light emission can take place. Of course, it would also be possible to make the side walls 53 opaque, if a light output is desired only to the bottom. The use of color filters for the different areas would also be conceivable in order to influence the color of the light emitted via the cover 51 in the desired manner.

Die Befestigung des Profilelements 51 an der Leuchteneinheit erfolgt im dargestellten Ausführungsbeispiel dadurch, dass das Profilelement 51 mit der Leuchteneinheit verrastet wird. Hierzu sind an den oberen Enden der Seitenwände 53 jeweils zur Innenseite ragende Vorsprünge 54 ausgebildet, welche ein einfaches Einrasten ermöglichen. Entsprechend der Darstellung in Fig. 6, welche einen Schnitt I-I der Fig. 2 zeigt, ist hierbei vorgesehen, dass die Vorsprünge 54 in entsprechende Ausnehmungen 36 an der Abdeckschiene 31 der Leuchteneinheit 30 eingreifen. Das Abdeckprofil 51 kann dementsprechend in einfacher Weise von der Unterseite her an die Leuchteneinheit 30 angesetzt und mit dieser verrastet werden. Alternativ hierzu wäre allerdings auch ein Verrasten mit der Tragschiene 10 denkbar. Die Schnittdarstellung in Fig. 6 zeigt ferner auch das Lampenbetriebsgerät 40 sowie das Kontaktierungselement 41 zur mechanischen Verankerung der Leuchteneinheit 30 an der Tragschiene 10 und zur elektrischen Kontaktierung, wobei auf diese Elemente allerdings im Folgenden nicht näher eingegangen werden soll, da sie bereits aus dem Stand der Technik bekannt sind.The attachment of the profile element 51 to the lamp unit takes place in the illustrated embodiment in that the profile element 51 is latched to the lamp unit. For this purpose, at the upper ends of the side walls 53 in each case protruding to the inside projections 54 are formed, which allow a simple engagement. As shown in Fig. 6 , which is a section II of the Fig. 2 shows, it is provided that the projections 54 engage in corresponding recesses 36 on the covering rail 31 of the lamp unit 30. Accordingly, the cover profile 51 can be attached in a simple manner from the bottom to the lamp unit 30 and locked with this. Alternatively, however, a locking with the support rail 10 would be conceivable. The sectional view in Fig. 6 also shows the lamp operating device 40 and the contacting element 41 for mechanically anchoring the lamp unit 30 to the support rail 10 and for electrical contact, but these elements will not be discussed in more detail below, since they are already known from the prior art.

Eine Besonderheit des Profilelements 51 besteht ferner darin, dass dieses an seinen Stirnseiten offen ist und seine Länge auf die Länge der Leuchteneinheit 30 abgestimmt ist. Insbesondere ist vorgesehen, dass das Profilelement 51 geringfügig kürzer ist als die Leuchteneinheit 30. Für den Fall, dass bei dem mit den transparenten Abdeckungen 50 nachzurüstenden Lichtbandsystem 100 die Leuchteneinheiten 30 unmittelbar aufeinander folgend angeordnet sind, hat dies zur Folge, dass die nachträglich daran befestigten Profilelemente 50 jeweils einen geringfügigen Abstand untereinander aufweisen. Bspw. beträgt dieser Abstand im montierten Zustand etwa 5mm, was zur Folge hat, dass sich aufgrund von Temperaturänderungen ergebende Längenveränderungen der Profilelemente 51 aufgefangen werden können. Trotz allem bleibt der Eindruck einer die Leuchteneinheiten 30 über die gesamte Länge hinweg umfassenden transparenten Abdeckung im Wesentlichen erhalten.A special feature of the profile element 51 is further that this is open at its end faces and its length is matched to the length of the lamp unit 30. In particular, it is provided that the profile element 51 is slightly shorter than the lamp unit 30. In the event that in the retrofitted with the transparent covers 50 Lichtbandsystem 100, the lighting units 30 are arranged directly following one another, this has the consequence that the subsequently attached thereto Profile elements 50 each have a slight distance from each other. For example. this distance is about 5mm in the assembled state, with the result that due to temperature changes resulting changes in length of the profile elements 51 can be collected. Despite all this, the impression of a transparent cover covering the luminaire units 30 over the entire length is essentially retained.

Dabei ist anzumerken, dass nicht zwingend jeder Leuchteneinheit eine separate Abdeckung zugeordnet sein muss. Denkbar wäre auch, mehrere, vorzugsweise allerdings maximal drei Leuchteneinheiten gleichzeitig mit der Abdeckung zu umgeben. In diesem Fall entspricht dann die Länge des Profilelements in etwa der Gesamtlänge der zu umgebenden Leuchteneinheiten, ist allerdings vorzugsweise wiederum etwas kürzer bemessen, um eine temperaturbedingte Längenveränderung auffangen zu können.It should be noted that not necessarily each lamp unit must be assigned a separate cover. It would also be conceivable to surround a plurality, but preferably a maximum of three, lighting units simultaneously with the cover. In this case, then the length of the profile element corresponds approximately to the total length of the surrounding lighting units, but is preferably again slightly shorter, in order to catch a temperature-induced change in length can.

Zusätzlich wird die Funktion sowie der optische Eindruck des gesamten Systems durch den Einsatz von Stirnteilen verbessert, die nachfolgend beschrieben werden sollen. Die Ausgestaltung der Stirnteile, die vorzugsweise ebenfalls transparent ausgestaltet sind, ist dabei in den Fig. 7 bis 9 dargestellt, wobei Fig. 7 eine perspektivische Ansicht, Fig. 8 eine Seitenansicht sowie Fig. 9 eine Ansicht der Stirnteile von der Oberseite her zeigt.In addition, the function and the visual impression of the entire system is improved by the use of front parts, which will be described below. The design of the end parts, which are preferably also designed to be transparent, is in the Fig. 7 to 9 shown, where Fig. 7 a perspective view, Fig. 8 a side view as well Fig. 9 shows a view of the end parts from the top.

Die Stirnteile 60 weisen zunächst eine Platte 61 auf, deren Abmessungen dem Innenquerschnitt des Profilelements 51 entsprechen. Im oberen Bereich dieser Platte 61 ist dann eine Tasche 62 ausgebildet, welche es ermöglicht, das Stirnteil 60 auf einen Fassungshalter der Leuchteneinheit 30 aufzusetzen und mit diesem zu verrasten. Die Tasche 62 weist dementsprechend an ihrer Unterseite eine Abrundung auf, die der Form eines üblichen Fassungshalters entspricht. Ferner sind zur Innenseite vorragende Schnappelemente 63 vorgesehen, welche ein Einrasten ermöglichen. Die Oberseite der Platte 61 ist ferner derart ausgeführt, dass sich das Stirnteil 60 im montierten Zustand möglichst exakt an die Leuchteneinheit 30 anschmiegt.The end parts 60 initially have a plate 61 whose dimensions correspond to the inner cross section of the profile element 51. In the upper region of this plate 61, a pocket 62 is then formed, which makes it possible to put the front part 60 on a socket holder of the lamp unit 30 and to lock with this. The pocket 62 has accordingly on its underside a rounding, which corresponds to the shape of a conventional frame holder. Furthermore, protruding snap elements 63 are provided to the inside, which allow a snap. The top of the plate 61 is further designed such that the front part 60 in the mounted state clings as closely as possible to the lamp unit 30.

Fig. 10 zeigt hierbei den Endbereich einer an einer Tragschiene 10 montierten Leuchteneinheit 30, während hingegen Fig. 11 den gleichen Ausschnitt mit montiertem Stirnteil 60 zeigt. Der Darstellung in Fig. 10 ist hierbei entnehmbar, dass an den Seiten der Fassungshalter 32 Ausnehmungen 37 ausgebildet sind, in welche die Schnappelemente 63 der Stirnteile 60 eingreifen können. Zum Montieren der Stirnteile 60 werden diese also von der Unterseite her an die Leuchteneinheit 30 angesetzt und derart nach oben geschoben, dass die Tasche 62 auf die Fassungshalter 32 geschoben wird, bis letztendlich die Schnappelemente 63 in die Ausnehmungen 37 eingreifen. Hierdurch wird eine sichere Halterung der Stirnteile 60 ermöglicht. Auch das nachträgliche Montieren der Stirnteile 60 ist dementsprechend sehr einfach durchzuführen. Fig. 10 in this case shows the end portion of a mounted on a mounting rail 10 lamp unit 30 while while Fig. 11 the same section with mounted front part 60 shows. The representation in Fig. 10 In this case, it can be seen that recesses 37 are formed on the sides of the holder holders, into which the snap elements 63 of the end parts 60 can engage. To mount the end portions 60, these are thus attached from the bottom to the lamp unit 30 and pushed up so that the bag 62 is pushed onto the socket holder 32 until finally the snap elements 63 engage in the recesses 37. As a result, a secure mounting of the end parts 60 is made possible. The subsequent mounting of the end portions 60 is accordingly very easy to perform.

Die Stirnteile 60 sind wie zuvor erläutert ebenfalls vorzugsweise transparent ausgeführt. Dies hat zur Folge, dass sie sich nicht auf den transparenten Profilelementen 51 abzeichnen und dementsprechend der Eindruck einer die Leuchteneinheiten vollständig umschließenden transparenten Abdeckung verstärkt wird. Ferner verhindern die Stirnteile 60 ein Eindringen von Insekten oder großen Staubpartikeln in das Innere der Abdeckung 50, welche sich in unschöner Weise als dunkle Flecken abzeichnen würden. Letztendlich kann also durch den kombinierten Einsatz des Profilelements 51 mit den Stirnteilen 60 ein Schutzgrad für die transparente Abdeckung 50 gemäß IP40 erzielt werden.The end parts 60 are also preferably transparent, as explained above. As a result, they are not transparent Sign profile elements 51 and accordingly the impression of the lamp units completely enclosing transparent cover is reinforced. Further, the end portions 60 prevent insects or large dust particles from entering the interior of the cover 50, which would unfavorably appear as dark spots. Ultimately, therefore, a degree of protection for the transparent cover 50 according to IP40 can be achieved by the combined use of the profile element 51 with the end portions 60.

Schließlich sind die Stirnteile ferner auch derart ausgeführt, dass sie die temperaturbedingte Längenänderung der länglichen Profilelemente 51 nicht behindern. Diese können an den Außenseiten der Stirnteile 60 ungehindert entlang gleiten, so dass jederzeit eine vollständige Umschließung der Leuchteneinheiten 30 gewährleistet ist. Die Höhe zwischen der Rückwand der Tasche 62 und der Platte 61 eines Stirnteils beträgt dabei ca. 9mm bis 10mm. Diese Höhe hat sich als optimal herausgestellt, um temperaturbedingte Längsausdehnungen der Abdeckung 50 auszugleichen, sofern diese maximal drei Leuchteneinheiten gleichzeitig überdeckt. Ist dabei die Länge des Profilelements 51 derart, dass mehrere Leuchteneinheiten gleichzeitig umschlossen werden, so werden selbstverständlich die Stirnteile 60 ausschließlich an den jeweiligen letzten Fassungshaltern der gesamten Anordnung montiert.Finally, the end parts are also designed such that they do not hinder the temperature-induced change in length of the elongated profile elements 51. These can slide along the outer sides of the end parts 60 unhindered, so that at any time a complete enclosure of the lamp units 30 is ensured. The height between the rear wall of the pocket 62 and the plate 61 of a front part is about 9mm to 10mm. This height has been found to be optimal to compensate for temperature-related longitudinal expansions of the cover 50, provided that covers a maximum of three lighting units simultaneously. If the length of the profile element 51 is such that several lamp units are enclosed at the same time, it goes without saying that the end parts 60 are mounted exclusively on the respective last socket holders of the entire arrangement.

Mit Hilfe der zuvor beschriebenen Stirneile 60 kann also die Anordnung an ihren beiden Enden elegant und einfach abgeschlossen werden. Sollten allerdings mehrere Profilelemente 51 hintereinander angeordnet werden, so stellt sich dann das Problem, dass in den Übergangsbereichen Luftspalte auftreten, welche aus optischen Gründen vorzugsweise ebenfalls abgeschlossen werden sollten. Hierfür sind allerdings die vorgeschriebenen Stirnteile 60 offensichtlich nicht geeignet. Stattdessen werden in diesen Übergangsbereich spezielle Verbindungselemente angeordnet, wie sie in den Figuren 12-16 dargestellt sind.With the help of the previously described Stirneile 60 so the arrangement can be completed elegantly and easily at both ends. However, if a plurality of profile elements 51 are arranged one behind the other, then the problem arises that air gaps occur in the transition areas, which for optical reasons should preferably also be completed. For this, however, the prescribed end pieces 60 are obviously not suitable. Instead, special connecting elements are arranged in this transition region, as in the Figures 12-16 are shown.

Die Figuren 12-16 zeigen hierbei unterschiedliche Ansichten eines Verbindungselements 70, welches plattenförmig ausgestaltet ist. Die in etwa der Querschnittsform eines Profilelements 51 entsprechende Platte 71 ist hierbei an der Unterseite sowie seitlich von einem U-förmigen Rahmen 72 umgeben, wobei die Seitenwände 73 des Rahmens 72 an Ihren oberen Enden zur Innenseite ragende Vorsprünge 74 aufweisen. Diese Vorsprünge 74 dienen dazu, dass Verbindungselement 70 mit der Tragschiene 100 oder der Leuchteneinheit 30 zu verrasten.The Figures 12-16 show here different views of a connecting element 70, which is designed plate-shaped. The approximately in the cross-sectional shape of a profile element 51 corresponding plate 71 is in this case at the bottom and laterally surrounded by a U-shaped frame 72, wherein the side walls 73 of the frame 72 projecting at their upper ends to the inside Have projections 74. These projections 74 serve to lock the connecting element 70 to the mounting rail 100 or the lamp unit 30.

Wie in den Figuren 17 bis 21 dargestellt wird nunmehr das Verbindungselement 70 derart angeordnet, dass sich die Platte 71 zwischen den Fassungshaltern 32 zweier benachbarter Leuchteneinheiten 30 befindet. Der umlaufende Rahmen 72 ist dabei derart bemessen, dass er den Luftspalt zwischen zwei aneinandergrenzenden Profilelementen 51 abdeckt. Genau genommen ist die Form des Rahmens 72 derart gewählt, dass die Profilelemente 51 diesen übergreifen und sich dementsprechend nach wie vor bei Temperaturänderungen ungehindert ausdehnen bzw. zusammenziehen können. Das Verbindungselement 70 ist also vollständig innerhalb der Profilelemente 51 angeordnet, allerdings derart, dass grundsätzlich der Spalt zwischen zwei Profilelementen 51 geschlossen wird.As in the FIGS. 17 to 21 now the connecting element 70 is shown arranged such that the plate 71 is located between the socket holders 32 of two adjacent lamp units 30. The peripheral frame 72 is dimensioned such that it covers the air gap between two adjoining profile elements 51. Strictly speaking, the shape of the frame 72 is selected such that the profile elements 51 overlap it and can accordingly continue to expand or contract unhindered in the event of temperature changes. The connecting element 70 is thus arranged completely within the profile elements 51, but in such a way that in principle the gap between two profile elements 51 is closed.

Die Verbindungselemente 70 sind ebenso wie die Stirnteile 60 vorzugsweise aus einem transparentem Material gebildet, was den Vorteil mit sich bringt, dass im Stoßbereich zweier benachbarter Profilelemente 51 keine Dunkelstellen auftreten, da das Licht durch die Verbindungselemente 70 nicht abgeschottet wird. Wiederum wird allerdings der Vorteil erhalten, dass das Eindringen von Insekten oder anderen Partikeln, welche zu dunklen Flecken führen könnten, weitestgehend verhindert wird.The connecting elements 70, like the end parts 60, are preferably made of a transparent material, which has the advantage that no dark spots occur in the abutting region of two adjacent profile elements 51, since the light is not sealed off by the connecting elements 70. Again, however, the advantage is obtained that the penetration of insects or other particles, which could lead to dark spots, is largely prevented.

Letztendlich wird also durch die zuvor beschriebene transparente Abdeckung die Möglichkeit geschaffen, Lichtbandsysteme in einfacher Weise nachzurüsten. Dies stellt eine deutliche Erleichterung im Vergleich zu bekannten Lösungen dar. Bislang war nämlich bei bereits installierten Lichtbändern eine nachträgliche Ergänzung der Systeme mit Optiken, welche Endkappen benötigen, nur möglich, wenn die Leuchteneinheiten nachträglich verschoben bzw. nachgesetzt wurden, um einen Freiraum zum Anbringen der Endkappen zu ermöglichen. Durch die Verwendung der U-förmigen Profilelemente, welche vorzugsweise als extrudierte Kunststoffteile ausgebildet sind, ist dieses nachträgliche Versetzen bereits installierter Leuchteneinheiten allerdings nicht mehr erforderlich. Trotz allem kann durch die ergänzende Verwendung der Stirnteile und Verbindungselemente ein vollständiges Umschließen der Leuchteneinheiten erzielt werden.Ultimately, therefore, the possibility is created by the previously described transparent cover, retrofit lighting systems in a simple manner. This represents a significant relief compared to known solutions. So far, a supplementing of the systems with optics, which require end caps, so far was only possible if the lighting units were subsequently postponed or postponed to a free space for attaching the already installed light strips To allow end caps. By using the U-shaped profile elements, which are preferably formed as extruded plastic parts, this subsequent displacement of already installed lighting units, however, is no longer necessary. Despite all, the complementary use of the end parts and connecting elements complete enclosure of the lamp units can be achieved.
