Description

Die Erfindung betrifft eine Beleuchtungseinrichtung für Räume, insbesondere für Büroräume.The invention relates to a lighting device for rooms, in particular for offices.

Insbesondere in Büroräumen ist es wichtig, die Arbeitsfläche gut zu beleuchten, wobei aber zu lokalisierte hohe Leuchtdichten zu vermeiden sind. Außerdem möchte man im Bereich der Arbeitsfläche selbst, die Bewegungsfreiheit einschränkende Tischleuchten oder dergleichen vermeiden.In office rooms in particular, it is important to illuminate the work area well, but avoid localizing high luminance levels. In addition, one would like to avoid table lamps or the like that restrict freedom of movement in the area of the work surface itself.

Aufgabe der Erfindung ist es, eine diesen Erfordernissen gerecht werdende Beleuchtungseinrichtung, insbesondere für Büroräume zu schaffen. Erfindungsgemäß wird dies durch eine Beleuchtungseinrichtung erreicht, die gekennzeichnet ist durch:

  • mindestens eine nach oben strahlende Werferleuchte (7)
  • wenigstens ein im Bereich der Raumdecke (2) angeordnetes Lichtumlenkelement (8) zum Umlenken des von der bzw. den Werferleuchten (7) nach oben geworfenen Lichts nach unten, und
  • wenigstens eine die Raumdecke (2) neben dem bzw. den Lichtumlenkelement(en) (8) anstrahlende Zusatzleuchte (9).
The object of the invention is to provide a lighting device which meets these requirements, in particular for office spaces. According to the invention, this is achieved by a lighting device which is characterized by:
  • at least one projector lamp shining upwards (7)
  • at least one light deflecting element (8) arranged in the area of the ceiling (2) for deflecting the light thrown upwards by the projector lamp (s) (7), and
  • at least one additional light (9) illuminating the ceiling (2) next to the light deflecting element (s) (8).

Über die Werferleuchten und die Lichtumlenklamellen ist eine gezielte Beleuchtung bestimmter Raumbereiche, insbesondere der Arbeitsflächen möglich, wobei an der Raumdecke selbst keine elektrischen Leitungen verlegt werden müssen, sondern praktische Umlenkelemente anzubringen sind.Targeted lighting of certain areas of the room, in particular of the work surfaces, is possible via the projector lights and the light deflection slats, whereby no electrical cables have to be installed on the ceiling itself, but practical deflection elements have to be attached.

Da die Breite des Lichtkegels der Werferleuchten aufgrund der Blendungsgefahr nicht beliebig groß gemacht werden kann, und andererseits für einen angenehmen Raumeindruck auch der neben den Arbeitsflächen liegende Bereich ausgeleuchtet werden soll, ist erfindungsgemäß eine weitere Zusatzleuchte vorgesehen, die günstigerweise die Raumdecke anstrahlt und damit als indirekte diffuse Deckenbeleuchtung für eine Hintergrundbeleuchtung sorgt, die den durch die Werferleuchten und Lichtumlenkelemente erzeugten Lichtdruck auflöst. Es ergibt sich so bei hervorragender Ausleuchtung der Arbeitsflächen oder anderer gezielter Raumbereiche eine insgesamt angenehme Raumbeleuchtung, wobei die Zusatzleuchte vorzugsweise im Bereich der oberen Wandhälfte einer Wand angeordnet sein kann. Damit sind einerseits bei der Anstrahlung der Decke Blendungen ausgeschlossen und andererseits sind dann in der Decke überhaupt keine elektrischen Leitungen nötig.Since the width of the light cone of the projector lights cannot be made arbitrarily large due to the risk of glare and, on the other hand, the area next to the work surfaces should also be illuminated for a pleasant impression of the room, a further additional light is provided according to the invention, which advantageously illuminates the ceiling and thus as an indirect one diffuse ceiling lighting provides background lighting that resolves the light pressure generated by the projector lights and light deflection elements. This results in an overall pleasant room lighting with excellent illumination of the work surfaces or other targeted room areas, wherein the additional lamp can preferably be arranged in the region of the upper half of a wall. On the one hand, glare is excluded when illuminating the ceiling, and on the other hand no electrical cables are necessary in the ceiling.

Die erfindungsgemäße Beleuchtungseinrichtung erlaubt auch einen modularen Aufbau, bei dem aus den Komponenten Werferleuchte, Lichtumlenkelement, Zusatzleuchte zahlreiche verschiedene Raumsituationen beleuchtungsmäßig ideal erfaßt werden können, wobei zur Anpassung an den jeweiligen speziellen Raum und die Lage der darin befindlichen Arbeitsflächen die Grundelemente der Beleuchtungseinrichtung im wesentlichen gleich bleiben können und lediglich in ihrer relativen Anordnung angepaßt werden müssen. Dies erlaubt vor allem bei größeren Bürogebäuden einen modularen kostengünstigen Aufbau.The lighting device according to the invention also permits a modular structure in which numerous different room situations can be ideally detected from the components of the projector lamp, light deflecting element, additional lamp, the basic elements of the lighting device being essentially the same in order to adapt to the respective special room and the position of the work surfaces therein can remain and only have to be adjusted in their relative arrangement. This allows a modular, low-cost structure, especially for larger office buildings.

Gemäß einer bevorzugten Variante der Erfindung ist bei einer Beleuchtungseinrichtung für Räume mit wenigstens einer von einer Vorderseite aus zugänglichen Arbeitsfläche (beispielsweise Schreibtisch) vorgesehen, daß die Werferleuchte(n) und das bzw. die Umlenkelement(e) derart angeordnet sind, daß das Licht durch eine die Vorderseite der Arbeitsfläche enthaltende, gedachte Vertikalfläche hindurch auf die Arbeitsfläche gelangt. Bei einer derartigen Anordnung erfolgt also eine Beleuchtung von schräg hinten oben. Damit sind Blendungen durch auf den Tisch bzw. die Arbeitsfläche aufgelegte Gegenstände, wie beispielsweise Klarsichtfolien für eine vor der Vorderseite der Arbeitsfläche befindliche Person ausgeschlossen.According to a preferred variant of the invention, in the case of a lighting device for rooms with at least one work surface (for example a desk) which is accessible from the front, that the projector lamp (s) and the deflection element (s) are arranged in such a way that the light reaches the work surface through an imaginary vertical surface containing the front of the work surface. With an arrangement of this type, illumination takes place obliquely from behind and above. Glare from objects placed on the table or the work surface, such as, for example, transparent films for a person in front of the front of the work surface, is thus ruled out.

Weitere Vorteile und Einzelheiten der Erfindung werden anhand der nachstehenden Figurenbeschreibung näher erläutert.Further advantages and details of the invention are explained in more detail with reference to the description of the figures below.

Der in Fig. 1 gezeigte Raum 1 weist eine Raumdecke 2, eine Hinterwand 3 und eine Vorderwand 4 auf, in der die Fenster 5 angeordnet sind. Im Raum befindet sich eine Arbeitsfläche 6, die beleuchtet werden soll. Insgesamt soll ein angenehm beleuchteter Büroraum geschaffen werden.The room 1 shown in FIG. 1 has a room ceiling 2, a rear wall 3 and a front wall 4, in which the windows 5 are arranged. There is a work surface 6 in the room which is to be illuminated. Overall, a pleasantly lit office space is to be created.

Eine Werferleuchte 7, die vorzugsweise eine im wesentlichen punktförmige Lichtquelle (beispielsweise Quecksilberdampflampe oder Halogenglühlampe) und einen Reflektor aufweist, wirft Licht nach oben. An der Decke ist ein Lichtumlenkelement 8 (beispielsweise ein Spiegel) angeordnet, der das aus der Werferleuchte 7 stammende Licht nach unten auf die Arbeitsfläche 6 hin umlenkt. Außerdem ist in der der Vorderwand 4 gegenüberliegenden Hinterwand 3 eine Zusatzleuchte 9 angeordnet, die die Raumdecke 2 anstrahlt und somit für eine diffuse Hintergrundbeleuchtung sorgt. In Fig. 1 ist mit strichlierten Linien der Beleuchtungsstärkenverlauf dieser von der Zusatzleuchte 9 hervorgerufenen Hintergrundbeleuchtung auf der Höhe der Arbeitsfläche 6 angedeutet. Mit strichpunktierten Linien ist der Beleuchtungsstärkenverlauf jenes Lichtanteiles eingezeichnet, der aus der Werferleuchte 7 stammt und über das Lichtumlenkelement 8 auf die Arbeitsfläche 6 gelangt. Insgesamt ergibt sich eine gute Ausleuchtung des Arbeitsplatzes, ohne jedoch in den danebenliegenden Bereichen eine Beleuchtungsstärke zu haben, denn in diesen Bereichen übernimmt die Zusatzleuchte mit ihrer Hintergrundbeleuchtung eine ergänzende Ausleuchtung.A projector lamp 7, which preferably has an essentially point-shaped light source (for example mercury vapor lamp or halogen incandescent lamp) and a reflector, throws light upwards. A light deflecting element 8 (for example a mirror) is arranged on the ceiling, which deflects the light coming from the projector lamp 7 downwards onto the work surface 6. In addition, an additional light 9 is arranged in the rear wall 3 opposite the front wall 4, which illuminates the ceiling 2 and thus provides diffuse background lighting. In Fig. 1, dashed lines indicate the illuminance curve of this backlight caused by the additional light 9 at the height of the work surface 6. The course of the illuminance of that part of the light which comes from the projector lamp 7 and reaches the work surface 6 via the light deflection element 8 is drawn in with dash-dotted lines. Overall, there is good illumination of the workplace, but without having an illuminance in the adjacent areas, because in these areas the additional light with its backlighting takes on additional illumination.

Um Blendungen zu vermeiden, ist es günstig, wenn die Zusatzleuchte im oberen Bereich der Raumwand 3 angeordnet ist und praktisch nur die Decke (also kaum die Wände) großflächig anstrahlt. Eine geschützte und optisch ansprechende Unterbringung der Zusatzleuchte 9 im Inneren der Raumwand 3 ist möglich, wie dies die Fig. 1 beispielsweise zeigt.In order to avoid glare, it is advantageous if the additional light is arranged in the upper area of the room wall 3 and practically only illuminates the ceiling (ie hardly the walls) over a large area. Protected and visually appealing accommodation of the additional light 9 in the interior of the room wall 3 is possible, as shown in FIG. 1, for example.

Eine gute Aufteilung der Raumausleuchtung durch die Werferleuchten einerseits und die Zusatzleuchte andererseits ergibt sich dann, wenn die Werferleuchten und die Zusatzleuchte an gegenüberliegenden Raumenden angeordnet sind, wie dies in Fig. 1 gezeigt ist, wobei es günstiger ist, wenn die Lichtumlenkelemente näher bei den zugehörigen Werferleuchten liegen. Damit ist es möglich, daß die Werferleuchten 9 präzise die Lichtumlenkelemente 8 treffen, sodaß im wesentlichen die gesamte Lichtintensität (beispielsweise mindestens 80%) der Werferleuchten auf die Lichtumlenkelemente (und nicht auf die danebenliegenden Decken und Wandbereiche) trifft. Es soll also über die Lichtumlenkelemente eine definierte Lichtführung gewährleistet sein, während die großflächige Hintergrundbeleuchtung über die Zusatzleuchte 9 bewerkstelligt wird.A good distribution of the room lighting by the projector lights on the one hand and the additional light on the other hand results when the projector lights and the additional light are arranged at opposite ends of the room, as shown in Fig. 1, it being more favorable if the light deflecting elements are closer to the associated projector lights. This makes it possible for the projector lights 9 to hit the light deflection elements 8 precisely, so that essentially the entire light intensity (for example at least 80%) of the projector lights strikes the light deflection elements (and not the adjacent ceilings and wall areas). A defined light guidance should thus be ensured via the light deflection elements, while the large-area background lighting is accomplished via the additional light 9.

Wie die Werferleuchten 7 kann auch die Zusatzleuchte 9 eine Quecksilberdampflampe aufweisen, welche bei geringem Stromverbrauch eine hohe Lichtausbeute erlaubt. Die Werferleuchten 7 können günstigerweise in der Fensterbrüstung angeordnet sein. Dort sind im allgemeinen die nötigen elektrischen Versorgungsleitungen leicht zugänglich.Like the projector lights 7, the auxiliary light 9 can also have a mercury vapor lamp, which allows a high luminous efficiency with low power consumption. The projector lights 7 can advantageously be arranged in the window parapet. The necessary electrical supply lines are generally easily accessible there.

Als Umlenkelemente kommen Spielge infrage, die eben oder gewölbt sein können.Spielge, which can be flat or curved, are suitable as deflection elements.

Wenn die Umlenkelemente aus mehreren Einzelreflektoren 8a bis 8d aufgebaut sind, wie dies beispielsweise in Fig. 2 der Fall ist, kann eine angenehme Auflösung der effektiven Lichtquelle in Teillichtquellen erzielt werden. Eine hohe Blendung aus bestimmten Betrachtungsrichtungen läßt sich somit vermeiden.If the deflection elements are constructed from a plurality of individual reflectors 8a to 8d, as is the case, for example, in FIG. 2, a pleasant resolution of the effective light source in partial light sources can be achieved. A high level of glare from certain viewing directions can thus be avoided.

Die Fig. 2 zeigt im Grundriß ein sogenanntes 2-Achsbüro, mit einem Hauptarbeitsplatz 6 und einem Besprechungstisch 6', der nur geringere Beleuchtungsstärken bedarf.Fig. 2 shows in the floor plan a so-called 2-axis office, with a main work station 6 and a meeting table 6 ', which only requires lower illuminance levels.

Über eine nach oben gerichtete Werferleuchte 7 wird Licht auf das aus vier Teilspiegeln 8a bis 8d bestehende Lichtumlenkelement 8 geworfen. Eine nicht dargestellte Lochmaske kann dabei sicherstellen, daß ein Großteil der Lichtintensität auf das Lichtumlenkelement trifft. Die Arbeitsfläche 6 weist eine Vorderseite 6a auf, vor der ein Stuhl 10 angeordnet ist. Das Licht aus der Werferleuchte 7 gelangt nun über das Umlenkelement 8 an der Raumdecke von schräg oben hinten (durch die gedachte Vertikalfläche, welche die Vorderseite 6a enthält hindurch) auf die Arbeitsfläche 6. Selbst wenn auf dieser Arbeitsfläche 6 spiegelnde Folien od.dgl. aufliegen, führt dies zu keiner Blendung der auf dem Stuhl 10 sitzenden Person. Auch im Bildschirm 11 kommt es durch die gezielte Beleuchtung der Fläche 6 zu keinen störenden Blendungen. Die Hintergrundbeleuchtung übernimmt die Zusatzleuchte 9, welche die Raumdecke anstrahlt.Light is thrown onto the light deflecting element 8 consisting of four partial mirrors 8a to 8d via an upward-pointing projector lamp 7. A shadow mask, not shown, can ensure that a large part of the light intensity strikes the light deflecting element. The work surface 6 has a front side 6a, in front of which a chair 10 is arranged. The light from the projector lamp 7 now reaches the work surface 6 via the deflecting element 8 on the ceiling from obliquely above (through the imaginary vertical surface which contains the front side 6a). Even if reflective foils or the like on this work surface 6. lying on, this does not lead to glare for the person sitting on the chair 10. In the screen 11, too, there is no disruptive glare due to the targeted illumination of the surface 6. The backlight is provided by the additional light 9, which illuminates the ceiling.

Die Fig. 3 zeigt im Grundriß ein sogenanntes 3-Achsbüro für zwei Mitarbeiter. Es sind zwei Arbeitsflächen 6 vorgesehen, die jeweils über Werferleuchten und Umlenkelemente 8 an der Decke beleuchtet werden. Die Hintergrundbeleuchtung kann eine Zusatzleuchte 9 besorgen.Fig. 3 shows in the floor plan a so-called 3-axis office for two employees. Two work surfaces 6 are provided, each of which is illuminated by projector lights and deflection elements 8 on the ceiling. The backlight can provide an additional light 9.

Fig. 4 zeigt im Grundriß ein sogenanntes 3-Achsbüro für drei Mitarbeiter. Wiederum sorgen an der Decke angeordnete passive Lichtumlenkelemente für die Beleuchtung der jeweiligen Arbeitsfläche 6. Eine einzige Zusatzleuchte 9 reicht zur Hintergrundbeleuchtung (anstrahlen der Raumdecke) aus.Fig. 4 shows in the floor plan a so-called 3-axis office for three employees. Again, passive light deflection elements arranged on the ceiling provide for the lighting of the respective work surface 6. A single additional light 9 is sufficient for the background lighting (illuminating the room ceiling).
