Description
Die Erfindung betrifft eine Flächenleuchte mit einer lichtleitenden Platte, die eine erste Großfläche, eine dieser gegenüberliegende zweite Großfläche und einen Rand in Form einer schmalen Stirnfläche hat, über die zeilenförmig angeordnete LEDs Licht einstrahlen, das die lichtleitende Platte diffus in Richtung der ersten Großfläche streut.The invention relates to a surface light having a light-conducting plate which has a first large area, a second large area opposite thereto and an edge in the form of a narrow end face, via which LEDs arranged in rows radiate light which diffuses the light-conducting plate diffusely in the direction of the first large area.
LED-Flächenleuchten mit diesen Merkmalen sind als sog. LED-Paneele in unterschiedlichen Ausführungen bekannt. Das über die erste, im Fall einer abgehängten oder Pendelleuchte untere Großfläche diffus abgestrahlte Licht beleuchtet eine unter der Leuchte befindliche Fläche, z. B. eine Tisch- oder eine Bodenfläche. Der übrige Raum bleibt weitgehend dunkel. Diese Beleuchtungssituation ist als sog. Höhleneffekt bekannt. Um eine freundlichere Beleuchtungsatmosphäre zu schaffen, werden deshalb häufig weitere Lichtquellen unterschiedlicher Art und Anbringung eingesetzt, die z. B. gegen die Decke strahlen und dadurch sog. indirektes Licht erzeugen.LED area lights with these features are known as so-called. LED panels in different versions. The light diffusely radiated via the first, in the case of a suspended or pendant light lower large area illuminates an area located under the light, z. B. a table or a floor surface. The rest of the room remains largely dark. This lighting situation is known as the so-called cave effect. To create a friendlier lighting atmosphere, therefore, more light sources of different types and attachments are often used, the z. B. against the ceiling and thereby generate so-called. Indirect light.

Der Erfindung liegt die Aufgabe zu Grunde, eine Flächenleuchte der eingangs genannten Art so zu verbessern, dass sie zu einer angenehmeren Beleuchtungssituation des Raumes führt.The invention is based on the object to improve a surface light of the type mentioned so that it leads to a pleasant lighting situation of the room.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass die lichtleitende Platte derart ausgebildet ist, dass sie nur einen ersten Teil des eingestrahlten Lichtes in Richtung der ersten Großfläche streut und einen zweiten Teil des eingestrahlten Lichtes in Richtung der zweiten Großfläche streut, also das von den LEDs erzeugte Licht in zwei im wesentlichen entgegengesetzten Richtungen abstrahlt.This object is inventively achieved in that the photoconductive plate is designed such that it scatters only a first portion of the incident light in the direction of the first large area and scatters a second portion of the incident light in the direction of the second large area, that is generated by the LEDs Light radiates in two substantially opposite directions.
Die Flächenleuchte nach der Erfindung vereinigt die Vorteile der bekannten LED-Flächenleuchten, d. h. flache Bauweise, große Gestaltungsfreiheit bezüglich der Abmessungen und des Umrisses sowie hohe Energieeffizienz, mit dem Vorteil der gleichzeitigen Schaffung einer indirekten Beleuchtung.The surface light according to the invention combines the advantages of the known LED area lights, d. H. Flat design, great design freedom in terms of dimensions and outline and high energy efficiency, with the advantage of the simultaneous creation of indirect lighting.
Die lichtleitende Platte kann zwar grundsätzlich aus einer einzigen, weitgehend transparenten Kunststoffplatte bestehen, die in an sich bekannter Weise lichtstreuend wirkt. Vorzugsweise umfasst die lichtleitende Platte jedoch zwei oder mehr Schichten, die z. B. sandwichartig miteinander verbunden sind und unterschiedliche Dicke haben können. Beispielsweise kann eine der Schichten das eingestrahlte Licht überwiegend in Richtung der ersten Großfläche streuen und die andere Schicht das eingestrahlte Licht überwiegend in Richtung der zweiten Großfläche streuen. Mindestens eine der Schichten kann auch lediglich aus einer lichtstreuenden Kunststofffolie oder einer Bedruckung, z. B. im Siebdruck, bestehen.Although the photoconductive plate may in principle consist of a single, largely transparent plastic plate, which acts in a manner known per se light scattering. Preferably, however, the photoconductive plate comprises two or more layers, e.g. B. are sandwiched together and may have different thickness. For example, one of the layers scattering the incident light predominantly in the direction of the first large area and the other layer scatter the incident light predominantly in the direction of the second large area. At least one of the layers may also consist only of a light-scattering plastic film or a print, for. B. in screen printing, exist.
Vorzugsweise hat die lichtleitende Platte mindestens eine teildurchlässige Reflexionsschicht, deren Transmissionsgrad das Verhältnis zwischen dem ersten und dem zweiten Teil des eingestrahlten Lichtes bestimmt. Der Grad der Durchlässigkeit der Reflexionsschicht kann im Fall deren Erzeugung durch Metallbedampfung durch die Schichtdicke, im Falle einer reflektierenden Metallfolie durch rasterartige Öffnungen eingestellt werden.Preferably, the photoconductive plate has at least one semitransparent reflection layer whose transmittance determines the ratio between the first and the second part of the irradiated light. The degree of transmissivity of the reflection layer can be adjusted by the film thickness in the case of its production by metal vapor deposition, or by grid-like openings in the case of a reflective metal foil.
Die Reflexionsschicht kann zwischen einer ersten lichtleitenden Schicht und einer zweiten lichtleitenden Schicht der lichtleitenden Platte angeordnet sein. Durch die Lage der Reflexionsschicht im Verhältnis zu den Hauptstrahlungsachsen der LEDs, also z. B. durch Wahl unterschiedlicher Dicken für die erste und die zweite lichtleitenden Schicht, lässt sich auf einfache Weise das Verhältnis zwischen dem ersten und dem zweiten Teil des in den beiden entgegengesetzten Richtungen abgestrahlten Lichtes bestimmen. In der Regel wird der in Richtung der ersten Großfläche gestreute und abgestrahlte Teil des Lichtes der Größere sein. Das Verhältnis kann auch umgekehrt gewählt werden, wenn ein besonders hoher Anteil indirekten Lichtes gewünscht wird. The reflection layer may be disposed between a first photoconductive layer and a second photoconductive layer of the photoconductive plate. Due to the position of the reflection layer in relation to the main radiation axes of the LEDs, ie z. Example, by choosing different thicknesses for the first and the second photoconductive layer, can be determined in a simple manner, the ratio between the first and the second part of the radiated in the two opposite directions of light. As a rule, the part of the light scattered and emitted in the direction of the first large area will be the larger one. The ratio can also be chosen vice versa, if a particularly high proportion of indirect light is desired.
Die lichtstreuende Platte kann, wie an sich bekannt, eine Schicht mit eingebetteten, reflektierenden oder lichtstreuenden Partikeln umfassen.The light-diffusing plate can, as is known, comprise a layer with embedded, reflective or light-scattering particles.
Alternativ oder zusätzlich kann mindestens eine der Großflächen der lichtleitenden Platte lichtstreuende Mikrostrukturen haben.Alternatively or additionally, at least one of the large areas of the light-guiding plate can have light-scattering microstructures.
Eine nachträgliche Veränderung des Verhältnisses der zwei abgestrahlten Anteile des eingestrahlten Lichtes ist möglich, wenn mindestens auf der zweiten Großfläche der lichtleitenden Platte Blenden angeordnet sind. Diese können zur Veränderung der Fläche des Lichtaustrittes beweglich, insbesondere verschiebbar sein. Um auch das auf diese Blenden gestreute Licht zu nutzen, können die Blenden mindestens auf ihrer Innenseite, d. h. auf ihrer der jeweiligen Großfläche zugewandten Seite, reflektierend ausgebildet sein.A subsequent change in the ratio of the two radiated portions of the incident light is possible if diaphragms are arranged at least on the second large area of the light-guiding plate. These can be movable, in particular displaceable, for changing the surface of the light exit. In order to use the light scattered on these panels, the panels can at least on their inside, d. H. be formed on its side facing the respective large area, reflective.
Eine andere oder zusätzliche Möglichkeit zur Beeinflussung der Anteile des in den beiden entgegengesetzten Richtungen abgestrahlten Lichtes besteht, wenn die Anordnung der LEDs und die lichtleitende Platte rechtwinklig zu deren Großflächen relativ zueinander verschiebbar sind. Dadurch wird die Ebene, in der die Hauptstrahlrichtungen der LEDs liegen, im Verhältnis z. B. zu einer Mittelebene oder einer Reflexionsschicht der lichtleitenden Platte einstellbar.Another or additional possibility for influencing the proportions of the light emitted in the two opposite directions is when the arrangement of the LEDs and the photoconductive plate are displaceable relative to one another at right angles to their large surfaces. As a result, the plane in which the main beam directions of the LEDs are in the ratio z. B. adjustable to a center plane or a reflective layer of the photoconductive plate.
Eine weitere Möglichkeit zur Steuerung der Lichtverteilung ergibt sich, wenn die LEDs in mindestens zwei Zeilen angeordnet sind, von denen jede vorzugsweise an eine eigene, einstellbare Stromversorgung angeschlossen ist. Dadurch erhöht sich gleichzeitig die Beleuchtungsstärke, die durch das direkte und das indirekte Licht erzeugt werden. Wenn die LED-Zeilen an eigene und getrennt einstellbare Stromversorgungen angeschlossen sind, lassen sich die Beleuchtungsstärken, die durch das direkte und das indirekte Licht erzeugt werden, unabhängig voneinander einstellen.Another possibility for controlling the light distribution results when the LEDs are arranged in at least two rows, each of which is preferably connected to its own, adjustable power supply. This simultaneously increases the illuminance generated by the direct and indirect light. If the LED lines are connected to separate and separately adjustable power supplies, the illuminance levels generated by the direct and indirect light can be adjusted independently of each other.
Die Flächenleuchte nach der Erfindung kann als Hängeleuchte oder als Wandvorsatzleuchte ausgebildet sein.The surface light according to the invention can be designed as a suspended luminaire or as a wall mounted luminaire.
In beiden Fällen hat sie an ihrem Gehäuse, das in dem Fachmann bekannter Weise ausgebildet sein kann, entsprechend unterschiedliche Befestigungen. Die zeilenförmigen LEDs können bei polygonalem oder kreisförmigem Umriss der Flächenleuchte je nach Größe deren Fläche und gewünschter Beleuchtungsstärke über einen Teil des Umfangsrandes oder über den gesamten Umfang in einem Abstand voneinander angeordnet sein, der unter Berücksichtigung der thermischen Belastungen der einzelnen LED und der wärmeleitenden Eigenschaften des die LEDs und die wärmeleitenden Platte aufnehmenden und haltenden Gehäuses gewählt ist.In both cases, it has on its housing, which may be formed in the manner known in the art, correspondingly different fasteners. The line-shaped LEDs can be arranged with a polygonal or circular outline of the surface light depending on the size of their surface and desired illuminance over a portion of the peripheral edge or over the entire circumference at a distance from each other, taking into account the thermal loads of the individual LED and the heat-conducting properties of the the LEDs and the thermally conductive plate receiving and holding housing is selected.
