In this way, the latching connection can be particularly close and thus effectively formed at the point at which the correspondingly tight transitional region between the optical element and the carrier element is located.
Vorzugsweise ist dabei die Rastverbindung durch das wenigstens eine Rastelement einerseits und einen der zwei Schenkel der Seitenwand des Trägerelements andererseits gebildet. Auf diese Weise lässt sich die Rastverbindung besonders einfach und doch wirkungsvoll gestalten.Preferably, the latching connection is formed by the at least one latching element on the one hand and one of the two legs of the side wall of the carrier element on the other hand. In this way, the locking connection can be particularly simple and yet effective.
Vorzugsweise umfasst die Leuchte außerdem ein weiteres längliches, sich parallel zur Längsachse erstreckendes optisches Element zur optischen Beeinflussung des von der LED-Lichtquelle abgestrahlten Lichts, wobei das weitere optische Element in Richtung der Längsachse mit dem zuerst genannten optischen Element überlappend angeordnet ist. Hierdurch lässt sich der Übergangsbereich zwischen den beiden optischen Elementen besonders einfach geeignet dicht gestalten. Herstellungstechnisch besonders vorteilhaft sind dabei vorzugsweise das optische Element und das weitere optische Element derart geformt, dass sie - in einem Schnitt parallel zu der Längsachse betrachtet - ineinandergreifende, insbesondere formschlüssig ineinandergreifende Endbereiche aufweisen.Preferably, the luminaire further comprises a further elongate optical element extending parallel to the longitudinal axis for optically influencing the light emitted by the LED light source, wherein the further optical element overlaps in the direction of the longitudinal axis with the first-mentioned optical element is arranged. As a result, the transition region between the two optical elements can be designed to be particularly dense in a suitable manner. In terms of manufacturing technology, the optical element and the further optical element are preferably shaped in such a way that they-viewed in a section parallel to the longitudinal axis-have intermeshing, in particular interlocking, end regions.
Vorzugsweise ist die Leuchte derart gestaltet, dass das optische Element und das weitere optische Element parallel zu der Längsachse mit Spiel gelagert angeordnet sind. Hierdurch lassen sich besonders geeignet im Fall von Temperaturschwankungen Längenänderungen der beiden optischen Elemente auffangen.Preferably, the lamp is designed such that the optical element and the further optical element are arranged parallel to the longitudinal axis with play. This makes it particularly suitable in the case of temperature fluctuations absorb changes in length of the two optical elements.
Vorzugsweise weist die Leuchte weiterhin ein Stirnteil auf, das an einem Längsendbereich des Trägerelements mit Letzterem verbunden ist, wobei das optische Element an das Stirnteil anliegend angeordnet ist. Auf diese Weise lässt sich an dem betreffenden stirnseitigen Endbereich des optischen Elements besonders geeignet eine entsprechende Dichtigkeit erzielen.Preferably, the luminaire further comprises a front part which is connected to the latter at a longitudinal end region of the carrier element, wherein the optical element is arranged adjacent to the front part. In this way, a corresponding density can be achieved particularly suitably at the respective front end region of the optical element.
Vorzugsweise weist die Leuchte weiterhin ein Halteelement zur Halterung der Leuchte, insbesondere an einer Tragschiene, auf, wobei das Trägerelement derart gestaltet ist, dass in einem Schnitt normal zu der Längsachse betrachtet durch das Trägerelement ein erstes Kompartiment und ein zweites Kompartiment gebildet sind, die durch einen Trennbereich des Trägerelements vollständig voneinander getrennt sind und wobei in dem ersten Kompartiment die LED-Lichtquelle angeordnet ist und in dem zweiten Kompartiment das Halteelement. Auf diese Weise lässt sich eine geeignete Dichtigkeit zwischen den beiden Kompartimenten erzielen; somit sind mit Bezug auf die Gestaltung des Halteelements größere Freiheiten gegeben. Zudem lässt sich auf diese Weise erzielen, dass kein Licht aus dem ersten Kompartiment in das zweite Kompartiment gelangt und von dort die Leuchte verlässt, was im Allgemeinen unerwünscht ist.Preferably, the lamp further comprises a holding element for supporting the lamp, in particular on a mounting rail, wherein the carrier element is designed such that viewed in a section normal to the longitudinal axis through the carrier element, a first compartment and a second compartment are formed by a separation region of the carrier element are completely separated from each other and wherein in the first compartment the LED light source is arranged and in the second compartment the holding element. In this way, a suitable tightness between the two compartments can be achieved; thus greater freedom is given with respect to the design of the retaining element. In addition, it can be achieved in this way that no light from the first compartment enters the second compartment and leaves the lamp from there, which is generally undesirable.
Herstellungstechnisch vorteilhaft besteht das Trägerelement aus einem gebogenen Bauteil, insbesondere aus einem gebogenen Blechteil, wobei der Trennbereich durch wenigstens einen schlaufenartigen Bereich des Trägerelements gebildet ist.In terms of manufacturing technology, the carrier element consists of a bent component, in particular of a bent sheet metal part, wherein the separating region is formed by at least one loop-like region of the carrier element.

Durch das Trägerelement 1 ist eine Seitenwand 11 und eine zu Letzterer parallele weitere Seitenwand 12 der Leuchte gebildet.By the
Weiter umfasst die Leuchte eine LED-Lichtquelle 2, die an dem Trägerelement 1 angeordnet ist, sowie ein längliches, sich parallel zur Längsache L erstreckendes optisches Element 3 zur optischen Beeinflussung eines, von der LED-Lichtquelle 2 abgestrahlten Lichts, wobei das optische Element 3 zwischen der Seitenwand 11 einerseits und der weiteren Seitenwand 12 andererseits angeordnet ist.Furthermore, the luminaire comprises an LED light source 2, which is arranged on the
In
In dieser Beschreibung wird davon ausgegangen, dass die Leuchte gegenüber der Vertikalen so orientiert ist, dass der Verbindungsschenkel 17 horizontal ausgerichtet ist und sich die beiden U-Schenkel bzw. die beiden Seitenwände 11, 12 von dem Verbindungsschenkel 17 aus nach unten hin erstrecken. Im Allgemeinen kann jedoch auch eine andere Orientierung der Leuchte vorgesehen sein.In this description, it is assumed that the lamp is oriented relative to the vertical so that the connecting
Durch die beiden freien, hier also unteren Endbereiche der beiden Seitenwände 11, 12 ist vorzugsweise ein Lichtaustrittsbereich der Leuchte gebildet, durch den hindurch das von der LED-Lichtquelle 2 abgestrahlte Licht zumindest teilweise die Leuchte verlässt. Das optische Element 3 ist hier in diesem Lichtaustrittsbereich angeordnet. Insbesondere kann durch eine nach unten weisende Fläche des optischen Elements 3 eine Lichtaustrittsfläche 39 der Leuchte gebildet sein.Due to the two free, in this case lower end regions of the two
Bei dem optischen Element 3 kann es sich, wie beim hier gezeigten Beispiel der Fall, um ein linsenartiges Element handeln. Das optische Element 3 ist vorzugsweise aus einem festen Material, beispielsweise Kunststoff gefertigt; beispielsweise kann es sich bei dem optischen Element 3 um ein Spritzgussteil handeln. Insbesondere ist das optische Element 3 vorzugsweise derart gestaltet, das es aus lediglich einem Stück besteht.The
Die LED-Lichtquelle 2 kann vorteilhaft, wie gezeigt, an einem nach unten weisenden Flächenbereich des Verbindungsschenkels 17 angeordnet sein.The LED light source 2 can advantageously be arranged, as shown, on a downwardly facing area of the connecting
Die LED-Lichtquelle 2 weist vorteilhaft eine Platine 21 auf, sowie mehrere, auf einem nach unten weisenden Flächenbereich der Platine 21 angeordnete LEDs 22, die vorzugsweise entlang einer, zu der Längsachse L parallelen Geraden angeordnet sind. Wie aus
Beim gezeigten Beispiel ist durch den U-förmigen Bereich mit den beiden Seitenwänden 11, 12 einerseits und das optische Element 3 andererseits ein Innenraum 15 der Leuchte gebildet, wobei die LED-Lichtquelle 2 in diesem Innenraum 15 angeordnet ist.In the example shown, by the U-shaped area with the two
Die Leuchte ist derart gestaltet, dass die Seitenwand 11 des Trägerelements 1 elastisch gegen das optische Element 3 drückend angeordnet ist. Auf diese Weise lässt sich herstellungstechnisch vorteilhaft erzielen, dass der Innenraum 15 vor einem Eindringen von Staub, Fliegen und dergleichen geschützt ist. Insbesondere lässt sich hierdurch die Leuchte geeignet so gestalten, dass sie die Schutzart IP 50 erfüllt.The luminaire is designed such that the
Wie in
Die elastische Eigenschaft der Seitenwand 11 des Trägerelements 1 lässt sich besonders geeignet erzielen, wenn die Seitenwand 11 zwei Schenkel 111, 112 aufweist, die in einem Querschnitt normal zu der Längsachse L betrachtet eine V-Form bilden, wobei einer der zwei Schenkel 111, 112 gegen das optische Element 3 drückend angeordnet ist. In dem Querschnitt betrachtet ist auf diese Weise mit Bezug auf eine Mittelachse M der Leuchte durch einen der beiden Schenkel 111, 112 ein "innerer" Schenkel 112 gebildet und durch den anderen ein "äußerer" Schenkel 111. Beim gezeigten Beispiel drückt der Seitenwandbereich 11 mit einem oberen Endbereich des inneren Schenkels 112 gegen das optische Element. Auf diese Weise ist bei einfacher Erzielung der gewünschten Elastizität eine besonders geeignete Raumnutzung ermöglicht.The elastic property of the
Vorzugsweise ist das optische Element 3 mit Hilfe einer Rastverbindung an dem Trägerelement 1 gehalten angeordnet. Hierdurch lässt sich das optische Element 3 beim Zusammenbau der Leuchte besonders einfach mit dem Trägerelement 1 verbinden.Preferably, the
Außerdem kann das optische Element 3 über eine Schraubverbindung an dem Trägerelement 1 gehalten angeordnet sein. Auf diese Weise lässt sich eine besonders zuverlässige Halterung des optischen Elements 3 an dem Trägerelement 2 erzielen. Wie in den
Zur Bildung der Rastverbindung ist vorzugsweise an dem Seitenwandbereich 31 des optischen Elements 3 ein Rastelement 33 ausgebildet, das insbesondere mit Bezug auf die Mittelachse M von dem Seitenwandbereich 31 nach außen weisend ausgebildet ist. Besonders raumsparend ist dabei das Rastelement 33 an einem oberen Endbereich des Seitenwandbereichs 31 ausgebildet. Wie beim gezeigten Beispiel der Fall, ist die Rastverbindung durch das wenigstens eine Rastelement 33 einerseits und einen der zwei Schenkel 111, 112 der Seitenwand 11 des Trägerelements 1, hier den inneren Schenkel 112 andererseits gebildet. Insbesondere kann es sich bei dem wenigstens einen Rastelement 33 um eine Rastnase handeln, die einen oberen Endbereich des inneren Schenkels 112 rastend umfasst.To form the latching connection, a latching
Wie exemplarisch aus
Beim gezeigten Beispiel weist das optische Element 3 außerdem einen entsprechenden weiteren flügelartigen Bereich 32' auf, von dem sich der weitere Seitenwandbereich 31' nach oben erstreckt. Durch den zuerst genannten flügelartigen Bereich 32 und den weiteren flügelartigen Bereich 32' ist dabei die Lichtaustrittsfläche 39 gebildet.In the example shown, the
Wie aus
Vorzugsweise erstreckt sich der Seitenwandbereich 31 über die gesamte Länge des optischen Elements 3. Mit anderen Worten ist die Länge des optischen Elements 3 gleich groß wie die Länge λ des Seitenwandbereichs 31. Auf diese Weise lässt sich die beschrieben Dichtigkeit vorteilhaft über die gesamte Länge des optischen Elements 3 erzielen.Preferably, the
Das weitere optische Element 4 ist dabei in Richtung der Längsachse L mit dem zuerst genannten optischen Element 3 überlappend angeordnet. Auf diese Weise lässt sich auch in diesem Bereich vorteilhaft eine geeignete staubdichte Verbindung bilden. Zudem lässt sich so erzielen, dass der Übergangsbereich zwischen dem optischen Element und dem weiteren optischen Element bei Betrachtung der Leuchte im Betriebszustand besonders wenig auffällig erscheint.The further optical element 4 is arranged overlapping in the direction of the longitudinal axis L with the first-mentioned
Vorzugsweise sind dabei das optische Element 3 und das weitere optische Element 4 derart geformt, dass sie - in einem Schnitt parallel zu der Längsachse L betrachtet - ineinandergreifende, insbesondere formschlüssig ineinandergreifende Endbereiche 39, 49 aufweisen. Auf diese Weise lässt sich sozusagen an dem zuerst genannten optischen Element 3 ein "männlicher" Endbereich 39 bilden und an dem weiteren optischen Element 4 ein hierzu korrespondierend geformter "weiblicher" Endbereich 49.In this case, the
Vorzugsweise ist dabei die Gestaltung derart, dass das optische Element 3 und das weitere optische Element 4 parallel zu der Längsachse L mit Spiel gelagert angeordnet sind. Auf diese Weise ist ermöglicht, dass sich die beiden optischen Elemente 3, 4 im Fall einer Temperaturschwankung ausdehnen können, ohne dass unerwünschte Spannungen auftreten und sich auch wieder zusammenziehen können, ohne dass sich die Überlappung auflöst. In
Insbesondere kann das Stirnteil 5 hierzu einen nach unten weisenden Wandbereich 51 aufweisen, der in Anlage gegen das optische Element 3 angeordnet ist. Im gezeigten Beispiel weist das optische Element 3 hierzu einen stirnseitigen Endbereich mit einem nach oben weisenden Flächenbereich auf, den der nach unten weisende Wandbereich 51 des Stirnteils 5 entsprechend dicht kontaktiert. Hierdurch lässt sich die gewünschte Dichtigkeit erzielen, wohingegen auch hier bei einem lediglich stirnseitigen Aneinanderfügen eine solche Dichtigkeit nicht erzielbar wäre.In particular, the
Auf diese Weise ist zudem das Stirnteil 5 bei äußerer Betrachtung der Leuchte besonders wenig auffällig. So lässt sich insbesondere ein besonders homogen erscheinender Lichtabgabebereich erzielen.In this way, the
Die Leuchte kann dafür vorgesehen sein, an einem Leuchtenträgerelement, beispielswiese einer (in den Figuren nicht gezeigten) Tragschiene montiert zu werden. Insbesondere kann es sich bei der Leuchte um eine Lichtbandleuchte handeln.The luminaire can be provided to be mounted on a luminaire support element, for example a support rail (not shown in the figures). In particular, the luminaire may be a continuous line luminaire.
Hierzu kann die Leuchte ein, perspektivisch und exemplarisch in
Außerdem lässt sich durch die Trennung der beiden Kompartimente 15, 16 geeignet erzielen, dass kein Licht der LED-Lichtquelle 2 aus dem ersten Kompartiment 15 in das zweite Kompartiment 16 gelangt und aus diesem - unerwünscht - nach außen tritt.In addition, can be achieved by the separation of the two
Zur Bildung des Trennbereichs 17 kann insbesondere vorgesehen sein, dass das Trägerelement 1 wenigstens einen schlaufenartigen Bereich 18 bildet.To form the
Die anmeldungsgemäße Leuchte zeichnet sich bei besonders kostengünstiger und Prozess-sicherer Herstellung durch eine geeignete Dichtigkeit, insbesondere Staubdichtigkeit aus; ein Eindringen von Staub, aber auch kleinen Fliegen u. s. w. in einen Innenbereich der Leuchte lässt sich geeignet verhindern. Die Leuchte eignet sich beispielsweise besonders für einen Einsatz in einem Lebensmittelgeschäft oder dergleichen.The lamp according to the application is characterized by a particularly cost-effective and process-reliable production by a suitable tightness, in particular dustproofness; Ingress of dust, but also small flies u. s. w. in an interior of the lamp can be suitably prevented. For example, the luminaire is particularly suitable for use in a grocery store or the like.
