- the first and second walls 21 and 22 are each formed as elastically flexible latching fingers 8.
- the two latching fingers 8 each have a latching nose 13 pointing into the receiving cavity 6.
- the latching fingers 8 form an integral part of the profile body 2.
- the profile body 2 is in a tapered foot region 14 in the latching fingers 8 on.

- the in Fig. 1 shown sealing elements 10, which in the illustrated embodiment have a circular cross-section, inserted into the hollow channels 9. Due to their circular cross-section, the sealing elements 10 protrude partially into the receiving cavity 6.
- the locking fingers 8 are spread elastically to the left above or right below.
- the elastically spread latching fingers 8 move back to their original position, in which they engage around the opposite longitudinal sides of the cover strip 5 in a form-fitting manner.
- the movement of the cover strip 5 in the receiving cavity 6 has also caused that the preferably elastically deformable sealing elements 10 have deformed such that they rest in the region of the opposite longitudinal sides of the cover 5 sealingly against the cover strip 5. Due to their elasticity, the sealing elements 10 are pressed against the cover strip 5 and thereby cause an effective seal of the receiving cavity 7 from the environment. An arbitrarily strong deformation of the sealing elements 10 is prevented by the limit stops 12 on the holding elements 11. Accordingly, an excessive and thus disadvantageous for the sealing effect deformation of the sealing elements 10 is avoided in an advantageous manner.
- the limit stops 12 limit the maximum penetration depth of the cover strip 5 into the receiving cavity 6 and thus also the maximum deformation of the sealing elements 10.
- the cover strip 5 After releasing the cover strip 5 press the elastically deformed and thus biased sealing elements 10, the cover strip 5 in Fig. 2 to the bottom left. As a result, the cover strip 5 is pressed without play against the locking lugs 13. The position of the latching noses 13 thus determines the relative position of the cover strip 5 relative to the light emitting diodes 4 of the LED carrier strip 3. This defines predeterminable relative position of the cover strip 5 relative to the light emitting diodes 4 makes it possible in an advantageous manner, a desired optical effect of the cover strip 5, which depends on their distance from the LEDs 4, comply.
- the cover strip 5 has the cross section of a plano-convex converging lens. The optical effect of such a lens has proved to be particularly advantageous for spatially targeted illumination of food in refrigerators.
- Fig. 2 the insulated wall 32 of a refrigerated cabinet is partially shown.
- the interior 34 of the refrigerator is located in Fig. 2 on the left side of the wall 32.
- the LED light strip 1 according to the invention with its profile body 2 is accordingly mounted on the inside of the wall 32 and the light emitted from the LEDs 4 through the transparent cover strip 5 light illuminates the interior 34 of the cabinet.
- An attached to the inside of the wall 32 light aperture 35 prevents the immediate visual contact of a person who in Fig. 2 from above into the interior 34, with the LED light strip 1.
- the screen 35 does not form part of the LED light strip 1.
- Each of the holding devices 20 designed as clip holders has an in Fig. 2 lower headband 36 and an in Fig. 2 upper bracket 37, which protrude at right angles from the wall 32 in the interior 34.
- the holding device 20 is held here by means of a screw on the wall 32, the screw 38 and nut 25 in Fig. 2 can be seen.
- the cross section of the profile body 2 is provided with a pivot finger 16 and a locking arm 17.

Abstract
Description
Die vorliegende Erfindung betrifft eine LED-Lichtleiste insbesondere für den Einbau in Kühlmöbel wie beispielsweise Kühltruhen oder Tiefkühltruhen in Lebensmittelmärkten. Die LED-Lichtleiste dient dabei dem Zweck, die in dem Kühlmöbel zum Verkauf bereitgehaltenen Lebensmittel in vorteilhafter Weise zu beleuchten.The present invention relates to a LED light strip in particular for installation in refrigeration cabinets such as freezers or freezers in food markets. The LED light strip serves the purpose of illuminating the food kept ready for sale in the refrigerator for sale in an advantageous manner.
Es sind herkömmliche Leuchtstoffröhren bekannt, die insbesondere in Kühlmöbeln von Lebensmittelmärkten zum Ausleuchten des Innenraums des Kühlmöbels verwendet werden. Zu diesem Zweck werden die Leuchtstoffröhren im oberen Bereich der Innenseiten der Wandungen des Kühlmöbels angebracht. Bei den bekannten Leuchtstoffröhren ist es nachteilig, dass das Licht nicht räumlich zielgerichtet in einem bestimmten Raumwinkelabstrahlbereich, sondern gleichmäßig in alle Raumrichtungen abgestrahlt wird. Für die Zwecke der verkaufsfördernden Beleuchtung von in Kühlmöbeln bereitgehaltenen Lebensmitteln ist es jedoch wünschenswert, eine Beleuchtungseinrichtung zur Verfügung zu haben, mit deren Hilfe das Licht gezielt in einem bestimmten Raumwinkelabstrahlbereich abgestrahlt werden kann.There are known conventional fluorescent tubes, which are used in particular in refrigeration furniture of food markets for illuminating the interior of the refrigerator. For this purpose, the fluorescent tubes are mounted in the upper region of the insides of the walls of the refrigerator. In the known fluorescent tubes, it is disadvantageous that the light is not spatially targeted in a certain Raumwinkelabstrahlbereich, but evenly emitted in all spatial directions. However, for the purpose of promoting lighting of food stored in refrigerated cabinets, it is desirable to have a lighting device that can be used to selectively radiate the light in a particular solid angle radiation area.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Beleuchtungseinrichtung insbesondere zur Beleuchtung des Innenraums eines Kühlmöbels in einem Lebensmittelmarkt zu schaffen, mit deren Hilfe die in dem Kühlmöbel befindlichen Lebensmittel derart in einem von der Beleuchtungseinrichtung aus gemessenen Raumwinkelabstrahlbereich beleuchtet werden können, dass sie zum Einen dem Kunden des Lebensmittelmarktes verkaufsfördernd präsentiert werden und zum Anderen den Kunden beim Betrachten der Lebensmittel in dem Kühlmöbel nicht blenden.It is therefore an object of the present invention to provide an illumination device, in particular for illuminating the interior of a refrigerated cabinet in a food market, with the help of which the foodstuffs located in the refrigerated cabinets can be illuminated in a solid angle radiation range measured by the illumination device such that they are on the one hand the customer of the food market are promoted presentation and on the other hand, the customer when viewing the food in the refrigerator do not dazzle.
Erfindungsgemäß wird eine LED-Lichtleiste insbesondere zur Verwendung in einem Kühlmöbel eines Lebensmittelmarktes vorgeschlagen, die einen länglichen Profilkörper, wenigstens eine längliche LED-Trägerplatte, auf der mehrere Leuchtdioden (LEDs) angeordnet sind, und eine transparente Abdeckleiste zum Abdecken der LED-Trägerplatte umfasst.According to the invention, a LED light strip is proposed in particular for use in a refrigerated cabinet of a food market, comprising an elongate profile body, at least one elongated LED support plate on which a plurality of light-emitting diodes (LEDs) are arranged, and a transparent cover strip for covering the LED support plate.
Das von den Leuchtdioden ausgestrahlte Licht tritt durch die transparente Abdeckleiste hindurch in einem von der LED-Lichtleiste aus gemessenen vorgebbaren Raumwinkelabstrahlbereich aus der LED-Lichtleiste aus und kann dementsprechend räumlich zielgerichtet zur verkaufsfördernden Beleuchtung der Lebensmittel eingesetzt werden. Insbesondere kann der vorgebbare Raumwinkelabstrahlbereich, in welchem das Licht von der LED-Lichtleiste abgestrahlt wird, in einem von oben zugänglichen Kühlmöbel schräg nach unten in den Innenraum des Kühlmöbels gerichtet werden, so dass ein von oben in das Kühlmöbel hineinschauender Kunde des Lebensmittelmarktes nicht geblendet wird. In vorteilhafter Weise ist der Profilkörper der LED-Lichtleiste mit einem ersten Aufnahmehohlraum versehen, in welchem sich die LED-Trägerplatte befindet. Darüber hinaus weist der Profilkörper zwei den ersten Aufnahmehohlraum zumindest teilweise begrenzende Haltevorsprünge auf, die jeweils eine der Längsseiten der LED-Trägerplatte umfassen und dadurch die LED-Trägerplatte formschlüssig in dem ersten Aufnahmehohlraum halten. Dies bewirkt im Vergleich zu anderen Befestigungsmethoden, wie beispielsweise das Befestigen der LED-Trägerleiste mit Hilfe von Klebstoff, eine sichere Verankerung der LED-Trägerleiste in dem Profilkörper.The light emitted by the light emanates light through the transparent cover strip in a measured from the LED light bar from predeterminable Raumwinkelabstrahlbereich from the LED light bar and can therefore be spatially targeted for promotional lighting of the food used. In particular, the predeterminable Raumwinkelabstrahlbereich in which the light is emitted from the LED light bar, be directed in an accessible from above refrigerated cabinets obliquely down into the interior of the cabinet, so that a looking into the refrigerator from above into the customer of the food market is not dazzled , Advantageously, the profile body of the LED light bar is provided with a first receiving cavity, in which the LED carrier plate is located. In addition, the profile body has two holding projections which at least partially delimit the first receiving cavity, each of which comprises one of the longitudinal sides of the LED carrier plate and thereby hold the LED carrier plate in a form-fitting manner in the first receiving cavity. This causes in comparison to other attachment methods, such as attaching the LED support bar with the aid of adhesive, a secure anchoring of the LED support bar in the profile body.
Vorzugsweise weist der Profilkörper der LED-Lichtleiste einen zweiten Aufnahmehohlraum, in welchem sich zumindest teilweise die Abdeckleiste befindet, sowie zwei zu dem zweiten Aufnahmehohlraum hin offene Hohlkanäle zur Aufnahme jeweils eines vorzugsweise elastisch verformbaren Dichtelements auf. Die Hohlkanäle verlaufen derart und das verformbare Dichtelement ist jeweils derart in den Hohlkanälen angeordnet, dass das jeweilige Dichtelement im Bereich einer Längsseite der Abdeckleiste dichtend an der Abdeckleiste anliegt. Dadurch wird der Innenraum der LED-Lichtleiste, insbesondere die LED-Trägerplatte samt zugehöriger Elektrik bzw. Elektronik, sicher vor dem Eindringen von Feuchtigkeit geschützt.Preferably, the profile body of the LED light strip has a second receiving cavity, in which at least partially the cover strip is, as well as two open towards the second receiving cavity hollow channels for receiving in each case a preferably elastically deformable sealing element. The hollow channels extend in such a way and the deformable sealing element is in each case arranged in such a way in the hollow channels, that the respective sealing element in the region of a longitudinal side of the cover strip bears sealingly against the cover strip. As a result, the interior of the LED light bar, in particular the LED carrier plate together with the associated electrical system or electronics, is reliably protected against the ingress of moisture.
In bevorzugter Weise begrenzen die Haltevorsprünge auf ihrer von der LED-Trägerplatte abgewandten Seite jeweils einen der Hohlkanäle zumindest teilweise. Zusätzlich oder alternativ können die zwei den ersten Aufnahmehohlraum zumindest teilweise von dem zweiten Aufnahmehohlraum trennenden Haltevorsprünge auf ihrer von der LED-Trägerplatte abgewandten Seite jeweils als Begrenzungsanschlag ausgebildet sein. Der Begrenzungsanschlag bewirkt, dass die Eindringtiefe der Abdeckleiste in den zweiten Aufnahmehohlraum beim Einsetzen derselben in den zweiten Aufnahmehohlraum begrenzt wird. Weiterhin zusätzlich oder alternativ zu der zumindest teilweisen Begrenzung der Hohlkanäle durch die Haltevorsprünge sind die Hohlkanäle vorzugsweise derart angeordnet, dass der Begrenzungsanschlag auch die Verformung der Dichtelemente beim Einsetzen der Abdeckleiste in den zweiten Aufnahmehohlraum begrenzt. Dadurch kann durch entsprechende Dimensionierung der Begrenzungsanschläge, d.h. durch die Wahl des Ausmaßes, um welches sich die Begrenzungsanschläge in den zweiten Aufnahmehohlraum hinein erstrecken, die maximale Verformung der Dichtelemente in besonders vorteilhafter Weise derart eingestellt werden, dass ausschließlich eine elastische Verformung der Dichtelemente eintritt. Auf diese Weise kann gewährleistet werden, dass beim Einsetzen der Abdeckleiste keine solchen plastischen Verformungen der Dichtelemente auftreten, welche die beabsichtigte Dichtwirkung beeinträchtigen könnten.In a preferred manner, the holding projections each delimit one of the hollow channels at least partially on their side remote from the LED carrier plate. In addition or as an alternative, the two holding projections which at least partially separate the first receiving cavity from the second receiving cavity may in each case be designed as limit stops on their side remote from the LED carrier plate. The limit stop causes the penetration depth of the cover strip into the second receiving cavity when inserting the same is limited in the second receiving cavity. Furthermore, in addition to or as an alternative to the at least partial delimitation of the hollow channels by the holding projections, the hollow channels are preferably arranged such that the limiting stop also controls the deformation of the hollow channels Sealing elements limited when inserting the cover strip in the second receiving cavity. As a result, by appropriate dimensioning of the limit stops, ie by the choice of the extent to which the limit stops extend into the second receiving cavity, the maximum deformation of the sealing elements can be adjusted in a particularly advantageous manner such that only an elastic deformation of the sealing elements occurs. In this way it can be ensured that no such plastic deformation of the sealing elements occur when inserting the cover, which could affect the intended sealing effect.
Der Profilkörper der LED-Lichtleiste weist vorzugsweise zwei Rastfinger mit jeweils einer Rastnase auf, welche den zweiten Aufnahmehohlraum zur Aufnahme der Abdeckleiste zumindest teilweise begrenzen. Die Rastnasen umfassen jeweils eine der sich gegenüber liegenden Längsseiten der Abdeckleiste, wodurch die Abdeckleiste formschlüssig in dem zweiten Aufnahmehohlraum gehalten wird.The profile body of the LED light strip preferably has two latching fingers, each with a latching nose, which at least partially limit the second receiving cavity for receiving the cover strip. The locking lugs each comprise one of the opposite longitudinal sides of the cover strip, whereby the cover strip is held in a form-fitting manner in the second receiving cavity.
Die Anordnung der Hohlkanäle sowie die Dimensionierung der Dichtelemente, der Rastfinger, der Rastnasen und der Abdeckleiste werden vorzugsweise derart gewählt, dass die elastisch verformten Dichtelemente die Abdeckleiste spielfrei gegen die Rastnasen vorspannen. Dadurch wird gewährleistet, dass sich die Abdeckleiste stets in einer definierten Relativlage insbesondere zu der LED-Trägerplatte und damit den Leuchtdioden befindet.The arrangement of the hollow channels and the dimensioning of the sealing elements, the latching fingers, the locking lugs and the cover strip are preferably selected such that the elastically deformed sealing elements bias the cover without play against the locking lugs. This ensures that the cover strip is always in a defined relative position, in particular to the LED support plate and thus the LEDs.
Die Rastfinger des Profilkörpers können jeweils einen Fußbereich aufweisen, in welchem sie jeweils einen der Hohlkanäle zumindest teilweise begrenzen. Durch die Ausbildung der Hohlkanäle wird der jeweilige Fußbereich der Rastfinger relativ zu den benachbarten Bereichen des Profilkörpers verjüngt, so dass die Rastfinger beim Einsetzen der Abdeckleiste in oder dem Entnehmen der Abdeckleiste aus dem ersten Aufnahmehohlraum leichter elastisch in von dem zweiten Aufnahmehohlraum wegweisende Richtungen aufgebogen werden können.The latching fingers of the profile body can each have a foot region in which they each delimit one of the hollow channels at least partially. Due to the design of the hollow channels, the respective foot region of the latching fingers is tapered relative to the adjacent regions of the profile body, so that the latching fingers when inserting the cover strip in or removing the cover strip from the first receiving cavity easily elastic in the second receiving cavity pioneering directions can be bent.
Die transparente Abdeckleiste dient vorzugsweise als optisches Element zur Bündelung oder Zerstreuung des von den Leuchtdioden abgestrahlten Lichts. Besonders bevorzugt ist es in diesem Zusammenhang, die Abdeckleiste in ihrer Längserstreckung zumindest abschnittsweise mit einem solchen Querschnitt auszubilden, der einer plan-konvexen Sammellinse entspricht.The transparent cover strip preferably serves as an optical element for bundling or dispersing the light emitted by the light emitting diodes. It is particularly preferred in this context, the cover strip in their longitudinal extent at least partially form with such a cross section, which corresponds to a plano-convex converging lens.
In vorteilhafter Weise können die Hohlkanäle teilkreisförmige Begrenzungswandungen mit einem Teilkreiswinkel von wenigstens 180° aufweisen. Dadurch wird gewährleistet, dass im Querschnitt beispielsweise kreisförmige Dichtelemente sicher in den Hohlkanälen gehalten werden.Advantageously, the hollow channels part-circular boundary walls having a pitch angle of at least 180 °. This ensures that in circular cross-section, for example, circular sealing elements are securely held in the hollow channels.
In besonders vorteilhafter Weise ist die erfindungsgemäße LED-Lichtleiste unabhängig von der Ausgestaltung und dem Vorhandensein des ersten und des zweiten Aufnahmehohlraums mit Hilfe einer Dreh- bzw. Schwenkbewegung um eine zu ihrer Längsachse parallele Achse an einer Wandung, insbesondere an der Innenseite einer Wandung eines Kühlmöbels, befestigbar. Hierzu weist der Querschnitt des Profilkörpers einen Drehpunktfinger und einen Rastfinger auf, so dass der Profilkörper eine längliche Drehkante und eine längliche Rastkante ausbildet, die zusammen eine Befestigungsebene aufspannen. Im Wege einer Drehbewegung des Profilkörpers um die Drehkante ist die LED-Leiste im Wesentlichen in der Befestigungsebene mit einer an der Wandung vorgesehenen Halteeinrichtung verrastbar.In a particularly advantageous manner, the LED light strip according to the invention is independent of the design and the presence of the first and the second receiving cavity by means of a rotary or pivotal movement about an axis parallel to its longitudinal axis on a wall, in particular on the inside of a wall of a refrigerated cabinet , attachable. For this purpose, the cross section of the profile body on a pivot finger and a latching finger, so that the profile body forms an elongated rotational edge and an elongate locking edge, which together span a mounting plane. By way of a rotational movement of the profile body about the rotational edge, the LED strip can be latched essentially in the fastening plane with a retaining device provided on the wall.
Der Querschnitt des Profilkörpers ist vorzugsweise derart gekrümmt oder abgewinkelt, dass eine erste Wand des Profilkörpers näher an der Befestigungsebene liegt als eine zweite Wand des Profilkörpers. In diesem Zusammenhang bildet die erste Wand eine längliche Greifkante aus, die zum Bewirken der Dreh- bzw. Schwenkbewegung des Profilkörpers um eine zu seiner Längsachse parallele Achse in Form der Drehkante von Hand ergreifbar ist.The cross section of the profile body is preferably curved or angled such that a first wall of the profile body is closer to the mounting plane than a second wall of the profile body. In this context, the first wall forms an elongate gripping edge which can be gripped by hand in order to effect the rotary or pivoting movement of the profile body about an axis parallel to its longitudinal axis in the form of the turning edge.
In diesem Zusammenhang liegt die Projektion der länglichen Greifkante in die Befestigungsebene vorzugsweise auf der von der Rastkante abgewandten Seite der Drehkante des Profilkörpers. Eine derartige Ausgestaltung der LED-Lichtleiste bringt den Vorteil mit sich, dass der Benutzer beim Bewirken der Drehbewegung des Profilkörpers durch Drücken gegen die Greifkante den Eindruck erhält, dass sich die LED-Leiste im Wesentlichen um ihre innerhalb des Profilkörpers liegende Längsachse dreht. Alternativ ist jedoch auch denkbar, die Projektion der Greifkante in die Befestigungsebene auf derjenigen Seite der Drehkante anzuordnen, auf welcher auch die Rastkante liegt.In this context, the projection of the elongate gripping edge in the mounting plane is preferably on the side remote from the locking edge side of the rotary edge of the profile body. Such an embodiment of the LED light strip has the advantage that the user receives the impression when pressing the rotary movement of the profile body by pressing against the gripping edge that the LED strip essentially rotates about its longitudinal axis lying within the profile body. Alternatively, however, it is also conceivable to arrange the projection of the gripping edge in the mounting plane on that side of the rotating edge on which also lies the locking edge.
Die erste und die zweite Wand des Profilkörpers werden in bevorzugter Weise von dem jeweiligen Rastfinger gebildet und begrenzen damit den zweiten Aufnahmehohlraum zumindest teilweise.The first and the second wall of the profile body are preferably formed by the respective latching fingers and thus limit the second receiving cavity at least partially.
In vorteilhafter Weise ist der Profilkörper in dem Bereich zwischen dem Drehpunktfinger und dem Rastfinger mit wenigstens einem Eindringhohlraum versehen. In diesen Eindringhohlraum kann wenigstens ein Befestigungselement zum Befestigen der Halteeinrichtung an der Wandung während der Dreh- bzw. Schwenkbewegung des Profilkörpers zumindest teilweise eindringen. Der Eindringhohlraum gewährleistet, dass bei der Gestaltung der Befestigung der Halteeinrichtung an der Wandung, beispielsweise an der Innenseite der Wandung eines Kühlmöbels, nicht auf raumgreifende Befestigungselemente zur Befestigung der Halteeinrichtung an der Wandung verzichtet werden muss.Advantageously, the profile body is provided in the region between the fulcrum finger and the latching finger with at least one penetration cavity. At least one fastening element for fastening the holding device to the wall can at least partially penetrate into this penetration cavity during the pivoting movement of the profile body. Ensures the penetration cavity that in the design of the attachment of the holding device on the wall, for example on the inside of the wall of a cabinet, must not be dispensed with expansive fasteners for attachment of the holding device on the wall.

Die Bewegung der Abdeckleiste 5 in den Aufnahmehohlraum 6 hinein hat außerdem bewirkt, dass sich die vorzugsweise elastisch verformbaren Dichtelemente 10 derart verformt haben, dass sie im Bereich der gegenüber liegenden Längsseiten der Abdeckleiste 5 dichtend an der Abdeckleiste 5 anliegen. Aufgrund ihrer Elastizität werden die Dichtelemente 10 an die Abdeckleiste 5 angedrückt und bewirken dadurch eine wirksame Abdichtung des Aufnahmehohlraums 7 gegenüber der Umgebung. Ein beliebig starkes Verformen der Dichtelemente 10 wird durch die Begrenzungsanschläge 12 an den Haltelementen 11 verhindert. Dementsprechend wird in vorteilhafter Weise eine zu starke und dadurch für die Dichtwirkung nachteilige Verformung der Dichtelemente 10 vermieden. Die Begrenzungsanschläge 12 begrenzen die maximale Eindringtiefe der Abdeckleiste 5 in den Aufnahmehohlraum 6 und damit auch die maximale Verformung der Dichtelemente 10. Beim Einsetzen der Abdeckleiste 5 in den Aufnahmehohlraum 6 des Profilkörpers 2 muss daher keine besondere Rücksicht dahingehend genommen werden, dass die Dichtelemente 10 in für die Dichtwirkung nachteiliger Weise beschädigt werden könnten.

Wie sich aus
Nachfolgend wird die Vorgehensweise zum Befestigen der LED-Lichtleiste 1 bzw. des Profilkörpers 2 an den Halteeinrichtungen 20 beschrieben:
- Zunächst wird die LED-Lichtleiste 1 von Hand derart gehalten, dass sich ihr Profilkörper 2 in einer gegenüber der in
Fig. 2 gezeigten Einbaudrehlage im Gegenuhrzeigersinn ein wenig verdrehten Drehlage befindet. Dann wird der Drehpunktfinger 16 samt seiner Drehkante 18 jeweils aufden unteren Haltebügel 36der Halteeinrichtungen 20 aufgesetzt,wobei ein Rückhaltevorsprung 41 andem unteren Haltebügel 36 verhindert, dass der Drehpunktfinger 16 inFig. 2 nach links aus der Halteeinrichtung 20 heraus gleiten kann. Anschließend wird derart von Hand gegen dieGreifkante 23 gedrückt, dass aufden Profilkörper 2 ein Drehmoment wirkt, welches eine Drehbewegung desProfilkörpers 2 um dieDrehkante 18 im Uhrzeigersinn bewirkt. Diese Drehbewegung hat zur Folge, dass sich der Rastarm 17mit seiner Rastkante 19 inFig. 2 von links dem jeweils oberen Haltebügel 37der Halteeinrichtungen 20 nähert.Die Rastkante 19 stößt schließlich anden Rastvorsprung 42 des oberen Haltebügels 37 an und biegt ihn inFig. 2 elastisch nach oben. Die im Uhrzeigersinn fortgesetzte Drehbewegung desProfilkörpers 2 bewirkt daraufhin, dass der Rastvorsprung 42 inFig. 2 entlang der Oberseite des Rastarms 17 gleitetbis der Rastvorsprung 42den Rastarm 17 hintergreift und ihn formschlüssig sowie sicher in der inFig. 2 gezeigten Lage inder Halteeinrichtung 20 hält.
- First, the LED light bar 1 is held by hand so that their
profile body 2 in a relation to the inFig. 2 The mounting posture shown is counterclockwise a little twisted rotational position. Then thefulcrum finger 16 together with itsrotational edge 18 is placed in each case on thelower retaining bracket 36 of the holdingdevices 20, wherein a retainingprojection 41 on thelower retaining bracket 36 prevents thefulcrum finger 16 inFig. 2 can slide out of the holdingdevice 20 to the left. Subsequently, it is pressed by hand against the grippingedge 23, that acts on theprofile body 2, a torque which causes a rotational movement of theprofile body 2 about the rotatingedge 18 in the clockwise direction. This rotational movement has the consequence that the latchingarm 17 with its lockingedge 19 inFig. 2 from the left approaches theupper headband 37 of the holdingdevices 20. The lockingedge 19 finally abuts the lockingprojection 42 of theupper retaining bracket 37 and bends it inFig. 2 elastic upwards. The continued in a clockwise direction of rotation of theprofile body 2 causes then, that the lockingprojection 42 inFig. 2 along the upper side of the latchingarm 17 slides until the latchingprojection 42 engages behind the latchingarm 17 and it positively and securely in the inFig. 2 shown position in the holdingdevice 20 holds.
Die Anordnung der Greifkante 23 in
Eindruck erhält, dass sich der Profilkörper 2 um eine im Wesentlichen innerhalb seines Querschnitts liegende Längsachse dreht, obwohl die tatsächliche Dreh- bzw. Schwenkbewegung um die von dem unteren Haltebügel 36 gehaltene Drehkante 18 erfolgt. Die den Einbau durchführende Person kann daher in Zusammenhang mit der erfindungsgemäßen LED-Lichtleiste 1 grundsätzlich dieselben Einbauhandgriffe vornehmen wie beim Einbau einer herkömmlichen Leuchtstoffröhre in deren Fassungen. Der Einbau herkömmlicher Leuchtstoffröhren erfolgt durch Einsetzen der elektrischen Kontakte der Leuchtstoffröhre in die zugehörigen Fassungen sowie anschließendes Verdrehen der Leuchtstoffröhre um ihre Längsachse. Die Gestaltung der erfindungsgemäßen LED-Lichtleiste 1 erfordert somit nicht, dass sich die einbauende Person mit ungewohnten Einbauhandgriffen anfreunden muss.The impression is that the
