Description

Die Erfindung betrifft eine Leuchte mit einer Lichterzeugungseinheit und einem Rahmenelement.The invention relates to a luminaire with a light-generating unit and a frame element.

Bei einer derartigen Leuchte muss im Rahmen der Herstellung das Rahmenelement mit der Lichterzeugungseinheit verbunden werden. Aus dem Stand der Technik ist es dabei bekannt, dass hierzu das Rahmenelement mittels Schrauben mit der Lichterzeugungseinheit verbunden wird. Die Herstellung dieser Verbindung erfordert daher einen nicht unwesentlichen Arbeitsaufwand. Zudem ist es durch diese Art der Verbindung erforderlich, das Rahmenelement mit einer bestimmten entsprechend geeigneten Mindestbreite zu gestalten; außerdem sind die Schrauben oft bei Betrachtung der fertig zusammengebauten Leuchte von außen zu erkennen. Dadurch sind die Gestaltungsmöglichkeiten der Leuchte mit Bezug auf deren äußeres Erscheinungsbild beeinträchtigt.In the case of such a luminaire, the frame element must be connected to the light-generating unit during production. It is known from the prior art that for this purpose the frame element is connected by means of screws with the light generating unit. The preparation of this compound therefore requires a not insignificant amount of work. In addition, it is necessary by this type of connection to make the frame element with a certain correspondingly suitable minimum width; In addition, the screws are often seen from the outside when looking at the fully assembled lamp. As a result, the design options of the lamp are affected with respect to their external appearance.

Dabei ist das Rahmenelement lediglich über Rastverbindungselemente an der Lichterzeugungseinheit gehalten angeordnet.According to the invention, a luminaire is provided, which has a light-generating unit for generating a light, and a frame element, by which a frame of the luminaire is formed. In this case, the frame element is held only via latching connection elements held on the light generating unit.

Auf diese Weise lässt sich das Rahmenelement besonders einfach mit der Lichterzeugungseinheit zum Zusammenbau der Leuchte verbinden. Weiterhin muss das Rahmenelement keine Löcher bzw. Ausnehmungen für Verbindungselemente wie beispielsweise Schrauben aufweisen, so dass es sich besonders schmal gestalten lässt. Hierdurch lässt sich das äußere Erscheinungsbild der Leuchte besonders vorteilhaft gestalten.In this way, the frame element can be particularly easily connected to the light generating unit for assembling the lamp. Furthermore, the frame element does not have holes or recesses for fasteners such as For example, have screws, so that it can be made very narrow.

Im gezeigten Ausführungsbeispiel umfasst die Lichterzeugungseinheit 2 eine Lichtleiterplatte 25 und eine LED-Lichtquelle 26, wobei durch Letztere das Licht erzeugt wird. Die Lichtleiterplatte 25 ist vorzugsweise planparallel zu der Trägerplatte 23 ausgerichtet angeordnet. Die Lichtleiterplatte 25 weist zwei große Hauptoberflächen auf, die über kleine, randseitige Schmalflächen miteinander verbunden sind. Die LED-Lichtquelle 26 ist dabei derart angeordnet, dass das Licht über eine Schmalseite der Lichtleiterplatte 25 in Letztere eingestrahlt wird. Im gezeigten Beispiel umfasst die LED-Lichtquelle 26 eine Platine, auf der mehrere LEDs, vorzugsweise längs einer horizontalen Gerade verlaufend, angeordnet sind.In the embodiment shown, the light generating unit 2 comprises a light guide plate 25 and an LED light source 26, the light being generated by the latter. The light guide plate 25 is preferably arranged aligned plane-parallel to the support plate 23. The light guide plate 25 has two major major surfaces, which are interconnected via small, edge-side narrow surfaces. The LED light source 26 is arranged such that the light is irradiated via a narrow side of the light guide plate 25 in the latter. In the example shown, the LED light source 26 includes a board on which a plurality of LEDs, preferably along a horizontal straight line running, are arranged.

Vorzugsweise ist dabei die LED-Lichtquelle 26 relativ zu der Lichtleiterplatte 25 verschiebbar gelagert angeordnet, insbesondere verschiebbar gegenüber dem Trägerblech 23. Die LED-Lichtquelle 26 kann insbesondere an einem LED-Lichtquellen-Trägerelement 27 angeordnet sein, das verschiebbar gegenüber dem Trägerblech 23 gelagert angeordnet ist.Preferably, the LED light source 26 is arranged displaceably mounted relative to the light guide plate 25, in particular displaceable relative to the support plate 23. The LED light source 26 may in particular be arranged on an LED light source support member 27 which is slidably mounted relative to the support plate 23 is.

Beim gezeigten Beispiel ist diese Lagerung derart, dass die LED-Lichtquelle 26 durch das LED-Lichtquellen-Trägerelement 27 auf diejenige Schmalseite der Lichtleiterplatte 25 zu verschoben werden kann, durch die das Licht in Letztere eingestrahlt wird. Dabei ist das LED-Lichtquellen-Trägerelement 27 so geformt, dass es zur Halterung der Lichtleiterplatte 21 dient; hierzu kann es insbesondere in der für den Betrieb der Leuchte vorgesehenen Stellung die Lichtleiterplatte 25 randseitig umfassen. In Fig. 1 ist wie erwähnt, lediglich ein Teilbereich der Lichterzeugungseinheit 2 skizziert, mit Bezug auf die Darstellung in Fig. 1 ein linker Teil. Vorzugsweise ist die Leuchte auf der entsprechenden gegenüberliegenden Seite bzw. rechts analog gestaltet, so dass sie hier eine entsprechende weitere LED-Lichtquelle mit einem weiteren LED-Lichtquellen-Trägerelement aufweist, so dass die Lichtleiterplatte 21 entsprechend von zwei gegenüberliegenden Seiten gehalten ist. Vorzugsweise ist zwischen der Lichtleiterplatte 21 und dem Trägerblech 23 noch ein Reflektor 28 angeordnet; hierdurch lässt sich der Wirkungsgrad der Lichtabgabe der Leuchte steigern. Vorzugsweise ist die Leuchte dabei so gestaltet, dass durch das LED-Lichtquellen-Trägerelement 27 und das weitere LED-Lichtquellen-Trägerelement die Lichtleiterplatte 25 und gegebenenfalls der Reflektor 28 an der restlichen Lichterzeugungseinheit 2 beispielsweise in Anlage an dem Trägerblech 23 gehalten sind.In the example shown, this storage is such that the LED light source 26 can be moved by the LED light source support member 27 to that narrow side of the light guide plate 25, through which the light is radiated into the latter. At this time, the LED light source support member 27 is formed so as to serve for supporting the light guide plate 21; For this purpose, it may include the edge of the light guide plate 25 in particular in the position provided for the operation of the lamp. In Fig. 1 As mentioned above, only a partial area of the light generating unit 2 is sketched, with reference to the illustration in FIG Fig. 1 a left part. Preferably, the lamp is designed analogously on the corresponding opposite side or on the right, so that it has a corresponding further LED light source with a further LED light source carrier element, so that the light guide plate 21 is held correspondingly from two opposite sides. Preferably, a reflector 28 is disposed between the light guide plate 21 and the support plate 23; This can increase the efficiency of the light output of the lamp. Preferably, the light is designed so that the light guide plate 25 and optionally the reflector 28 are held on the remaining light generating unit 2, for example, in contact with the support plate 23 by the LED light source support member 27 and the other LED light source support member.

Beim gezeigten Beispiel weist die Leuchte weiterhin eine lichtdurchlässige Abdeckscheibe 5 auf, durch die hindurch das Licht von der Leuchte nach außen abgegeben wird, so dass also durch die Abdeckscheibe 5 eine Lichtabgabefläche der Leuchte gebildet ist. Diese Abdeckscheibe 5 ist dabei an dem Rahmenelement 3 abgestützt angeordnet.In the example shown, the lamp further comprises a translucent cover 5, through which the light is emitted from the lamp to the outside, so that therefore by the cover 5, a light emitting surface of the lamp is formed. This cover 5 is arranged supported on the frame member 3.

Vorzugsweise weisen die Profilelemente 35 des Rahmenelements 3 hierzu jeweils einen horizontalen Schenkel 32 auf, auf dem die Abdeckscheibe 5 aufliegend gelagert angeordnet ist. Dieser Schenkel 32 kann sehr schmal gestaltet sein, da er nicht als Angriffselement für Verbindungselemente wie beispielsweise Schrauben dienen muss. Beispielsweise kann vorgesehen sein, dass der Schenkel 32 eine Breite aufweist, die maximal 8 mm beträgt. Die Leuchte kann hierdurch vorteilhaft so gestaltet werden, dass sie einen besonders schmalen sichtbaren Rand aufweist.For this purpose, the profile elements 35 of the frame element 3 preferably each have a horizontal leg 32, on which the cover plate 5 is arranged resting. This leg 32 can be made very narrow, since it does not have to serve as a driving element for fasteners such as screws. For example, it can be provided that the leg 32 has a width which is a maximum of 8 mm. The luminaire can thereby be advantageously designed so that it has a particularly narrow visible edge.

Mit der Leuchte lässt sich also ein besonders gutes Verhältnis zwischen der Größe der Lichtabgabefläche und dem sichtbaren Rahmen der Leuchte erzielen.With the lamp, therefore, a particularly good ratio between the size of the light emitting surface and the visible frame of the lamp can be achieved.

Im gezeigten Beispiel ist raum- und materialsparend die Abdeckscheibe 5 durch die Lichterzeugungseinheit 2 lagefixiert angeordnet. Insbesondere weist hierzu das LED-Lichtquellen-Trägerelement 27 eine nach unten weisende Anlagefläche 271 auf, die die Abdeckscheibe 5 in ihrer Lage von oben sichert.In the example shown, space and material saving the cover 5 is fixed in position by the light generating unit 2.

Weiterhin weist die Leuchte vorteilhaft ein vorzugsweise plattenförmiges optisches Element 6 auf, das planparallel zu der Abdeckscheibe 5 angeordnet ist und das ebenfalls an dem Rahmenelement 3 abgestützt angeordnet ist. Dabei kann es sich bei diesem optischen Element 6 insbesondere um ein optisches Element zur Lichtlenkung, beispielsweise um eine Prismenplatte handeln. Hierdurch lässt sich das von der Leuchte abgegebene Licht vorteilhaft entblenden.Furthermore, the lamp advantageously has a preferably plate-shaped optical element 6, which is arranged plane-parallel to the cover plate 5 and which is also arranged supported on the frame member 3. In this case, this optical element 6 may in particular be an optical element for directing the light, for example, to act a prismatic plate. As a result, the light emitted by the light can be de-emphasized advantageous.

Im gezeigten Beispiel weist die Leuchte außerdem noch ein weiteres, vorzugsweise plattenförmiges optisches Element 7 auf, das ebenfalls planparallel zu der Abdeckscheibe 5 angeordnet ist und das ebenfalls an dem Rahmenelement 3 abgestützt angeordnet ist. Hierbei kann es sich insbesondere um eine Diffusor-Platte oder eine Diffusor-Folie handeln. Wenn das weitere optische Element 7 diffus wirkend gestaltet ist, lässt sich eine besonders homogene Ausleuchtung der Lichtabgabefläche bis zum Rand hin erzielen.In the example shown, the lamp also has another, preferably plate-shaped optical element 7, which is also arranged plane-parallel to the cover plate 5 and which is also arranged supported on the frame member 3. This may in particular be a diffuser plate or a diffuser film. If the further optical element 7 is designed diffusively, a particularly homogeneous illumination of the light emission surface can be achieved up to the edge.

Im gezeigten Beispiel werden die Abdeckscheibe 5, das optische Element 6 und das weitere optische Element 7 durch Andruck der Anlagefläche 271 des das LED-Lichtquellen-Trägerelement 27 von oben fixiert gehalten.In the example shown, the cover 5, the optical element 6 and the further optical element 7 are held fixed by pressing the contact surface 271 of the LED light source support member 27 from above.

Durch die beschriebene Gestaltung der Leuchte lässt sich eine sehr homogene Ausleuchtung der Lichtabgabefläche erzielen, insbesondere eine gute Ausleuchtung bis zum Randbereich der Lichtabgabefläche hin.The described design of the luminaire makes it possible to achieve a very homogeneous illumination of the light emission surface, in particular a good illumination up to the edge region of the light emission surface.

Zum Zusammenbau der Lichterzeugungseinheit 2 lässt sich das Federelement 22 an dem Trägerblech 23 vormontieren. Die Leuchte ist vorzugsweise so gestaltet, dass sowohl die Lichterzeugungseinheit 2, als auch das Rahmenelement 3 in der Fertigung jeweils separat vormontiert werden können. Anschließend lassen sich die beiden genannten Teile dann zusammenbauen, und zwar ohne, dass hierfür ein weiteres Teil erforderlich wäre, also insbesondere schraubenlos und vorzugsweise ohne Zuhilfenahme eines Werkzeugs. Die Leuchte kann insbesondere weiterhin so gestaltet sein, dass sie aus der Lichterzeugungseinheit 2 und dem Rahmenelement 3 besteht, also keine weiteren Teile umfasst.To assemble the light generating unit 2, the spring element 22 can be preassembled on the carrier plate 23. The luminaire is preferably designed such that both the light-generating unit 2 and the frame element 3 can each be pre-assembled separately in the production. Subsequently, the two parts mentioned can then be assembled, without, for this purpose, a further part would be required, ie in particular screwless and preferably without the aid of a tool.
