Description

Die Erfindung betrifft eine elektrische Leuchte mit einem Leuchtengehäuse, das einen Boden, Seitenwandungen und eine Lichtaustrittsöffnung aufweist, die von einer lichtdurchlässigen Abdeckung, vorzugsweise einer klarsichtigen Abdeckung abgedeckt ist, wobei im Leuchtengehäuse mindestens eine elektrische Lichtquelle sowie mindestens ein Reflektor angeordnet ist, mittels dessen die von der Lichtquelle abgehenden Strahlen durch die Austrittsöffnung abstrahlend ausgerichtet werden.The invention relates to an electric lamp with a lamp housing, which has a bottom, side walls and a light exit opening, which is covered by a translucent cover, preferably a clear cover, wherein in the luminaire housing at least one electric light source and at least one reflector is arranged, by means of which be aligned radiating outgoing from the light source rays through the outlet opening.

Derartige Leuchten sind im Stand der Technik bekannt. Solche Leuchten werden beispielsweise als Bodeneinbauleuchten eingesetzt, wobei das Gehäuse flächenbündig eingebaut ist und die vorzugsweise klarsichtige Abdeckung ebenfalls bündig eingesetzt ist, wobei solche Leuchten auch mit Fahrzeugen überfahrbar sind.Such lights are known in the art. Such lights are used for example as floor lights, the housing is installed flush and the preferably transparent cover is also inserted flush, with such lights are also traversed with vehicles.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, eine elektrische Leuchte gattungsgemäßer Art zu schaffen, die insbesondere als Bodeneinbauleuchte für den gebäudenahen Einsatz geeignet ist, wobei unerwünschte Lichtemissionen vermieden sind und eine ausgewogene Außenbeleuchtung insbesondere von Gebäudefassaden oder dergleichen ermöglicht ist.Based on this prior art, the invention is based on the object to provide an electric lamp generic type, which is particularly suitable as a floor light for use close to the building, with unwanted light emissions are avoided and a balanced outdoor lighting in particular of building facades or the like is possible.

Zur Lösung dieser Aufgabe wird vorgeschlagen, dass im Gehäuse nahe dessen Boden ein Reflektor angeordnet ist, dessen Reflektorfläche als asymmetrische Wanne ausgebildet ist, sodass die Lichtstrahlen asymmetrisch aus der Lichtaustrittsöffnung austreten, und dass auf der der Reflektorfläche abgewandten Seite der Lichtquelle zwei weitere Reflektorelemente angeordnet sind, die mit Abstand voneinander gehalten sind und sich parallel zur Längsachse der Wanne erstrecken, wobei diese Reflektorelemente jeweils eine konkave Grundfläche aufweisen, die der Lichtquelle zugewandt ist und einen Teil der von der Lichtquelle ausgehenden Strahlen in Richtung auf die asymmetrische Wanne reflektieren, konkave innere Seitenflächen aufweisen, die einander zugewandt sind und einen Parabol ähnlichen Teilreflektor bilden, mittels dessen die Strahlen der Lichtquelle etwa gleichgerichtet zu den von der asymmetrischen Wanne abgehenden Lichtstrahlen gebündelt sind, sowie konkave äußere Seitenflächen aufweisen, mittels derer ein Teil der von der asymmetrischen Wanne reflektierten Strahlen ein Streulicht erzeugend gerichtet sind, welches einen beidseits neben dem Hauptstrahlungsbereich der Reflektor-Wanne befindlichen Streustrahl bildet.To solve this problem it is proposed that in the housing near the bottom of a reflector is arranged, the reflector surface is formed as an asymmetric trough, so that the light rays exit asymmetrically from the light exit opening, and that on the side facing away from the reflector surface of the light source, two further reflector elements are arranged , which are spaced apart and extend parallel to the longitudinal axis of the trough, these reflector elements respectively a concave base facing the light source and reflecting a portion of the rays emanating from the light source towards the asymmetric well, having concave inner side surfaces facing each other and forming a parabolic sub-reflector by which the rays of the light source approximate rectified are bundled to the outgoing light rays from the asymmetric pan, and have concave outer side surfaces, by means of which a part of the beams reflected from the asymmetric trough a scattered light are generating, which forms a located on both sides of the main radiation area of the reflector pan scattered beam.

Eine solche elektrische Leuchte kann beispielsweise als Bodeneinbauleuchte für den gebäudenahen Einsatz sehr nah an einem Gebäude angeordnet sein. Durch die entsprechende Ausbildung ist eine engstrahlendasymmetrische sanfte und weiche Anstrahlung von Gebäudefassaden ermöglicht. Hierbei kann die Außenbeleuchtung die Aufgabe übernehmen, die entsprechende Gebäudearchitektur und besondere Elemente der Gebäudestruktur visuell zu vermitteIn und hervorzuheben. Diese Anstrahlung der Gebäudefassaden und dergleichen erfolgt ohne störendes Streulicht für die Anrainer und die Nutzer des Gebäudes. Durch die fassadennahe Anordnung und die asymmetrische, zum Gebäude gerichtete Strahlungscharakteristik werden unerwünschte Lichtemissionen vermieden. Bei der Außenbeleuchtung wird zudem ein Streiflichtanteil erreicht, wodurch eine gewisse Schattigkeit und Erkennbarkeit von Strukturen bewirkt wird.Such an electric light can be arranged, for example, as a floor light for close-to-building use very close to a building. The appropriate training a narrow beam asymmetric soft and soft illumination of building facades is possible. Here, the outdoor lighting can take over the task, the appropriate building architecture and special To visually communicate and highlight elements of the building structure. This illumination of the building facades and the like is done without disturbing stray light for the residents and users of the building. Due to the arrangement close to the facade and the asymmetrical radiation characteristic directed towards the building, unwanted light emissions are avoided. In the outdoor lighting, a grazing light component is also achieved, whereby a certain shading and recognizability of structures is effected.

Insbesondere wird durch eine solche Leuchte eine sehr gute Lichtwirkung bei kontrastreicher Ausleuchtung einer Gebäudefassade erreicht, so dass Gebäudestrukturen gezielt hervorgehoben werden können. Die durch die entsprechende Ausbildung ermöglichte gebäudenahe Installation ermöglicht es, solche Leuchten auf dem eigenen Grundstück des Gebäudes zu montieren, also Nachbargrundstücke oder Nachbarflächen nicht nutzen zu müssen. Auch die Bewegungsfreiheit von Anrainern und Passanten im öffentlichen Bereich wird kaum beeinträchtigt.In particular, such a luminaire achieves a very good lighting effect with high-contrast illumination of a building facade, so that building structures can be highlighted in a targeted manner. The building-related installation, made possible by the appropriate training, makes it possible to install such luminaires on the building's own property, ie not having to use neighboring properties or neighboring areas. The freedom of movement of residents and passers-by in public areas is hardly affected.

Aufbauten, wie zum Beispiel Masten oder dergleichen im Gelände sind nicht erforderlich.Constructions, such as masts or the like in the field are not required.

Bevorzugt kann zudem vorgesehen sein, dass als Lichtquelle eine T5-Leuchtstofflampe vorgesehen ist, deren Längsachse parallel zur Längsachse der Wanne gerichtet ist.In addition, it can preferably be provided that the light source is a T5 fluorescent lamp whose longitudinal axis is directed parallel to the longitudinal axis of the trough.

Hierdurch wird bei hohem Wirkungsgrad ein relativ geringer Energieverbrauch realisierbar.As a result, a relatively low energy consumption can be realized with high efficiency.

Zudem ist vorgesehen, dass die Reflektoren oder Reflektorelemente um einen geringen Winkelgrad justierbar sind, vorzugsweise um etwa bis zu 5°.In addition, it is provided that the reflectors or reflector elements are adjustable by a small angular degree, preferably by about up to 5 °.

Durch diese Ausbildung ist eine Justage der Leuchte insbesondere im eingebauten Zustand ermöglicht.By this design an adjustment of the lamp is made possible in particular when installed.

Das Gehäuse weist eine in der Zeichnung oben angeordnete Lichtaustrittsöffnung 2 auf, die von einer lichtdurchlässigen Abdeckung, beispielsweise von einem klarsichtigen bruchfesten Glas abgedeckt ist. Im Leuchtengehäuse 1 ist bodennah ein Reflektor 3 angeordnet, dessen Reflektorfläche als asymmetrische Wanne ausgebildet ist, so dass die von einer Lichtquelle 4 ausgehenden Strahlen asymmetrisch etwa in Richtung des Pfeils 5 reflektiert werden. Auf der der Reflektorfläche des Reflektors 3 abgewandten Seite der Lichtquelle 4 sind zwei weitere Reflektorelemente 6, 7 angeordnet, die mit einem Abstand voneinander gehalten sind und sich parallel der Längsachse des wannenartigen Reflektors 3 erstrecken. Diese Reflektorelemente 6, 7 weisen jeweils eine konkave Grundfläche 8, 9 auf, die der Lichtquelle 4 zugewandt ist und einen Teil der von der Lichtquelle 4 ausgehenden Strahlen in Richtung auf den Reflektor 3 reflektieren. Des Weiteren weisen diese Reflektorelemente 6, 7 konkave innere Seitenflächen 10, 11 auf, die einander zugewandt sind und einen parabolähnlichen Teilreflektor bilden, mittels dessen die von der Lichtquelle 4 abgehenden Strahlen etwa gleichgerichtet zu den von der asymmetrischen Wanne (Reflektor 3) abgehenden Lichtstrahlen gebündelt sind. Des Weiteren weisen die Reflektoren 6, 7 konkave äußere Seitenflächen 12, 13 auf, mittels derer ein Teil der von der asymmetrischen Wanne (Reflektor 3) reflektierten Strahlen ein Streulicht erzeugend gerichtet sind, welches einen beidseits neben dem Hauptstrahlungsbereich (in Richtung 5) der Reflektorwanne (des Reflektors 3) befindlichen Streustrahl bildet.The luminaire has a luminaire housing 1, which may for example have a cuboid shape. The housing has a light exit opening 2 arranged at the top in the drawing, which is covered by a light-permeable cover, for example by a transparent, break-proof glass. In the luminaire housing 1, a reflector 3 is arranged close to the ground, whose reflector surface is formed as an asymmetric trough, so that the rays emanating from a light source 4 are asymmetrically reflected approximately in the direction of the arrow 5. On the side facing away from the reflector surface of the reflector 3 of the light source 4, two further reflector elements 6, 7 are arranged, which are held at a distance from each other and extend parallel to the longitudinal axis of the trough-like reflector 3. These reflector elements 6, 7 each have a concave base 8, 9, which faces the light source 4 and a part of the emanating from the light source 4 rays in the direction Reflect on the reflector 3. Furthermore, these reflector elements 6, 7 concave inner side surfaces 10, 11 which face each other and form a parabol-like partial reflector, by means of which the outgoing from the light source 4 beams approximately rectified to the outgoing of the asymmetric tub (reflector 3) light rays are. Furthermore, the reflectors 6, 7 have concave outer side surfaces 12, 13, by means of which a part of the rays reflected by the asymmetrical trough (reflector 3) are directed to produce a scattered light, which is located on either side of the main radiation area (in direction 5) of the reflector trough forms (the reflector 3) located scattered beam.

Die Lichtquelle 4 ist vorzugsweise eine T5-Leuchtstofflampe, deren Längsachse parallel zur Längsachse des Reflektors 3 gerichtet ist. Vorzugsweise sind die Reflektoren oder zumindest die Reflektorelemente 6, 7 um einen geringen Winkelgrad justierbar, vorzugsweise um etwa 5°, so dass nach dem Einbau der Leuchte, der vorzugsweise bodenseitig vorgesehen ist, eine Justage ermöglich ist. Durch eine solche elektrische Leuchte ist es einerseits möglich, eine unsichtbare und nicht störende Anordnung innerhalb des Bodens vor einem Gebäude vorzusehen, wobei durch die entsprechende Ausrichtung der Lichtstrahlen eine außerordentlich wirksame Fassadenbeleuchtung erreicht wird, die weder für die Menschen innerhalb des Gebäudes störend ist noch für die Anwohner oder dergleichen störende Lichtemissionen erzeugen.The light source 4 is preferably a T5 fluorescent lamp whose longitudinal axis is directed parallel to the longitudinal axis of the reflector 3. Preferably, the reflectors or at least the reflector elements 6, 7 are adjustable by a small angular degree, preferably by about 5 °, so that after installation of the lamp, preferably the bottom side is provided, an adjustment is possible.
