Das deutsche Gebrauchsmuster
Aufgabe der Erfindung ist es, eine Leuchte der eingangs genannten Art so weiterzubilden, dass diese mit mehreren gleichartigen Leuchtmitteln verwendet werden kann. Hierbei ist darauf zu achten, dass die Funktionsweise der allseitig abstrahlenden Optik beibehalten wird.The object of the invention is to develop a luminaire of the type mentioned so that it can be used with several similar bulbs. It is important to ensure that the functioning of the omnidirectional optics is maintained.
Die Aufgabe wird gelöst mit einer Leuchte mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Leuchte sind in den Unteransprüchen beschrieben.The object is achieved with a luminaire having the features of
Kern der Erfindung ist es, dass am Geräteträger Ausleger angebracht sind und dass auf den Auslegern jeweils eine Fassung für ein Leuchtmittel angebracht ist. Außerdem sind die Ausleger zumindest in Teilbereichen lichtdurchlässig ausgeführt. Dadurch ist gewährleistet, dass das von dem Leuchtmittel erzeugte Licht in alle Bereiche des Hohlkörpers abgestrahlt wird und damit die gesamte Optik als leuchtender Körper wirkt, der allseitig Licht abgibt.Core of the invention is that the device carrier jibs are mounted and that on the arms each a socket for a light source is mounted. In addition, the boom are designed to translucent, at least in some areas. This ensures that the light generated by the light source is emitted in all areas of the hollow body and thus the entire optics acts as a luminous body, which emits light on all sides.
In einer bevorzugten Ausführungsform sind als Leuchtmittel zwei einseitig gesockelte Gasentladungslampen vorgesehen. Ferner sind zwei Ausleger beidseitig in den Endbereichen mit dem Geräteträger verbunden, wobei jeder der Ausleger eine Fassung trägt und sich bei jedem der Ausleger in dem Bereich, in dem beim einen Ausleger die Fassung angeordnet ist, beim anderen Ausleger ein lichtdurchlässiger Bereich, insbesondere eine Öffnung, befindet. Um die allseitige Lichtabstrahlung zu verbessern können die Gasentladungslampen mit ihren freien Enden durch diese Öffnungen hindurchragen. Der sogenannte Coolspot, der kühlste Punkt der Gasentladungslampe, befindet sich bei diesem Lampentyp im Bereich des freien Endes. Da dieser Bereich vom Ausleger eng umschlossen ist, ist zumindest dann, wenn der Ausleger aus gut wärmeleitendem Material gefertigt ist, davon auszugehen, dass dieser Punkt auf einem gegenüber einer freistehenden Lampe auf niedrigem Temperaturniveau verbleibt und so der Wirkungsgrad der Lampe und damit der Leuchte optimiert ist.In a preferred embodiment, two single-ended gas discharge lamps are provided as the light source. Further, two arms are connected on both sides in the end regions with the equipment carrier, wherein each of the cantilevers carries a socket and in each of the cantilevers in the region in which the socket is arranged at one arm, the other arm a translucent area, in particular an opening , is located. In order to improve the all-round light emission, the gas discharge lamps can protrude with their free ends through these openings. The so-called Coolspot, the coolest point of the gas discharge lamp, is located near the free end in this type of lamp. Since this area is closely enclosed by the boom, at least when the boom is made of good heat-conducting material, it can be assumed that this point remains at a low temperature level compared to a freestanding lamp and thus optimizes the efficiency of the lamp and thus of the luminaire is.
Bevorzugt ist im Freiraum zwischen Leuchtmittel und Frontseite der Optik ein teillichtdurchlässiger Reflektor angeordnet. Dieser Reflektor kann aus zwei Reflektorwänden gebildet sein, welche so angeordnet sind, dass diese in spitzem Winkel aufeinander zulaufen, wobei die Stossstelle im Bereich des Leuchtmittels und der größte Abstand zwischen den beiden Reflektorwänden im Bereich der Frontseite ist. Der bzw. die Ausleger können den Reflektor tragen und so im Hohlkörper fixieren.Preferably, a partially transparent reflector is arranged in the free space between the light source and the front of the optics. This reflector may be formed of two reflector walls, which are arranged so that they converge at an acute angle to each other, wherein the impact point in the region of the illuminant and the largest distance between the two reflector walls in the region of the front side. The or the boom can carry the reflector and fix it in the hollow body.
Vorzugsweise werden in der erfindungsgemäßen Leuchte als Leuchtmittel eine, insbesondere zwei, Leuchtstofflampen des Typs TC-L, 28 Watt verwendet. Werden Lampen in diesem Leistungsbereich eingesetzt, kann die Aufteilung zwischen Direkt und Indirektanteil beispielsweise durch die Wahl der Reflexionseigenschaften und des Grades der Lichtdurchlässigkeit so eingestellt werden, dass die Aufteilung etwa 35 % für den Direktanteil und 65 % für den Indirektanteil beträgt. Hierbei ist zu beachten, dass die einschlägigen Normen, welche unter anderem Vorgaben zur Blendbegrenzung vorsehen, eingehalten werden. Im konkreten Fall wird als Reflektormaterial ein Aluminiumblech mit der Markenbezeichnung Miro 7 mit einem Lochanteil von mindestens 22% verwendet. Neben der erzeugten Lichtleistung durch die Lampen und die genannten Reflektoreigenschaften ist für die Einhaltung der einschlägigen Normen auch wesentlich, dass das Licht auch über die Frontseite und Seitenwände der Optik abgestrahlt werden. Insgesamt ermöglicht diese Bauweise in Verbindung mit den zuvor genannten bzw. vergleichbaren Leuchtstofflampen eine normkonforme Leuchte für anspruchsvolle Beleuchtungsaufgaben, wie beispielsweise die Beleuchtung von Bildschirmarbeitsplätze, zu schaffen, die gegenüber dem Stand der Technik einen niedrigeren Energieverbrauch aufweist.Preferably, one, in particular two, fluorescent lamps of the type TC-L, 28 watts are used in the luminaire according to the invention as a light source. If lamps are used in this power range, the division between direct and indirect component, for example, by the choice of the reflection properties and the degree of light transmission can be adjusted so that the distribution is about 35% for the direct component and 65% for the indirect component. It should be noted that the relevant standards, which provide, among other things, specifications for glare control, are complied with. In the specific case, an aluminum sheet with the brand name Miro 7 with a hole content of at least 22% is used as the reflector material. In addition to the light output generated by the lamps and the above-mentioned reflector properties, it is also essential for compliance with the relevant standards that the light is also emitted via the front and side walls of the optics. Overall, this construction in conjunction with the aforementioned or comparable fluorescent lamps allows a standard-compliant luminaire for demanding lighting tasks, such as the lighting of computer workstations to create, which has a lower energy consumption compared to the prior art.
Einerseits um die lichttechnischen Eigenschaften der Optik zu beeinflussen und andererseits wegen eines ansprechenden gestalterischen Effekts, ist im Inneren der Optik entlang der Seitenwände und der Fronseite ein perforiertes, vorzugsweise als Lochblech ausgeführtes Metallband angeordnet.On the one hand to influence the lighting properties of the optics and on the other hand because of an appealing design effect, a perforated, preferably designed as a perforated metal strip is arranged inside the optics along the side walls and the front side.
Die Optik selbst ist als Hohlkörper mit Frontseite und Seitenwände ausgeführt. Die Rückseite des Hohlkörpers wird mit dem Geräteträger verschlossen. Vorzugsweise sind die Frontseite und die Seitenwände einstückig aus einer Mikroprismenplatte gefertigt. Die Ecken zwischen Frontseite und Seitenwänden können in diesem Fall verrundet sein und sind durch Warmverformen des Kunststoffes gebildet. Die Bodenplatte der Abdeckung ist aus einer Mikropyramidenplatte oder in Sandwichbauweise aus einer glasklaren Bodenplatte mit darüber angeordneter Mikropyramidenplatte hergestellt, wobei die Frontseite und die Seitenwände mit der Bodenplatte verklebt sind. Auf der Oberseite der Optik kann eine lichtdurchlässige Abdeckplatte aufgelegt werden, um das Eindringen von Staub in den Hohlkörper zu vermeiden oder zumindest zu verringern. Der Vollständigkeit halber sei erwähnt, dass anstelle der Mikroprismenplatte bzw. der Mikropyramidenplatte, die sich dadurch auszeichnen, das die lichttechnisch wirksame Struktur in die Oberflächen der Platten eingearbeitet sind, auch glasklare Platten verwendet werden können und die lichttechnischen Eigenschaften durch Einlegen von zusätzlichen Elementen wie Folien oder Platten mit entsprechenden Strukturen erreicht werden können. Ebenfalls ist es möglich andere Strukturen wie beispielsweise Mikrolinsen oder dergleichen anstelle von Mikroprismen oder Mikropyramiden zu verwenden.The optic itself is designed as a hollow body with front and side walls. The back of the hollow body is closed with the equipment carrier. Preferably, the front side and the side walls are made in one piece from a microprism plate. The corners between the front and side walls can be rounded in this case and are formed by hot deformation of the plastic. The bottom plate of the cover is made of a micropyramidal plate or sandwiched from a clear bottom plate with a superimposed micropyramidal plate, with the front and side walls glued to the bottom plate. On top of the optics, a translucent cover plate can be placed in order to prevent or at least reduce the penetration of dust into the hollow body. For the sake of completeness, it should be mentioned that instead of the microprism plate or the micropyramidal plate, which are distinguished by the fact that the phototechnically active structure are incorporated into the surfaces of the plates, even clear plates can be used and the photometric properties by inserting additional elements such as films or plates with corresponding structures can be achieved. It is also possible to use other structures such as microlenses or the like instead of microprisms or micropyramids.
Die erfindungsgemäße Leuchte kann mittels eines Montageblechs in bekannter Art und Weise an einer Wand Decke montiert werden und so beispielsweise als Wandleuchte eingesetzt werden. Ebenfalls möglich ist die Verwendung der Leuchte in Verbindung mit einem Steher. Damit kann eine Stehleuchte gebildet werden. Andere Einsatzmöglichkeiten als Decken oder Pendelleuchte sind ebenfalls denkbar.The luminaire according to the invention can be mounted by means of a mounting plate in a known manner to a wall ceiling and so used for example as a wall lamp. Also possible is the use of the lamp in conjunction with a post. Thus, a floor lamp can be formed. Other uses as ceiling or pendant light are also conceivable.
