Abstract

Light fitting provides both direct and indirect lighting. The lamp reflectors are fitted with light outlet openings which are equipped with adjustable shutters. Diffusor or prism plates are positioned behind the light outlet openings. This arrangement provides any required or desirable degree of light intensity or light contrast by an adjustment of the shutters which can be carried out quickly and without difficulty both during the original fitting of the light unit as well as in rooms already equipped with lighting.

Description

I3eleuelltungsanlagc rür direkte und indirekte Beleuchtung Illumination system for direct and indirect lighting

nekanntlich sind Beleuchtungsart und Reflexionsgrade ausgedehnter Flächen im Gesichtsfeld, wozu im wesentlichen Decken und Wände zählen, so z wählen, daß eine als angenehm empfundene Leuchtdichteverteilung im Raum entsteht.It is not known that the type of lighting and the degree of reflection are more extensive Select areas in the field of vision, which essentially include ceilings and walls, that a luminance distribution that is perceived as pleasant is created in the room.

Zu geringe Leuchtdichte-Unterschiede bewirken einen monotonen Raumeindruck. Andererseits sollten Seuchtdichteunterschiede von im Blickfeld des Betrachters liegenden Objekten, die größer als 1:10 sind, vermieden werden, da sie als störend empfunden werden. Bezogen auf Beleuchtungsanlagen für direkte und indirekte Beleuchtung würde dies bedeuten, daß die Aufgabe darin zu sehen ist, die Leuchtendichte der von der direkten Ausstrahlung betroffenen Arbeitsflächen im Raum zu der Leuchtdichte der indirekt angestrahlten Decke in das richtige Verhältnis zu setzen. Geht man z.B. von einer an der Decke befindlichen Leuchte aus, die eine Leuchtdichte von 1000 cd/m² erbringt, dann sollte die dahinter liegende Deckenfläche eine Leuchtdichte von 100 cd/m² haben.Insufficient differences in luminance result in a monotonous spatial impression. On the other hand, there should be differences in epidemic density from those in the field of vision of the observer Objects that are larger than 1:10 should be avoided as they are perceived as annoying will. Would refer to lighting systems for direct and indirect lighting this means that the task is to be seen in the luminance density of the direct radiation affected work surfaces in the room to the luminance of the to put the indirectly illuminated ceiling in the right proportion. If you go e.g. from a luminaire on the ceiling that has a luminance of 1000 cd / m², then the ceiling surface behind it should have a luminance of 100 cd / m².

Es hat sich gezeigt, daß man mit den derzeit verfügbaren Beleuchtungsanlagen für direkte und indirekte Beleuchtung nicht in der Lage ist, ein gewünschtes bzw. gefordertes Leuchtdichteverhältnis, wie oben dargelegt, bei der Montage der Anlage oder bei einer Änderung der Zweckbestimmung eines mit Leuchten ausgestatteten Raumes ohne Schwierigkeiten zu erzielen. Zum mindesten gab es bisher keine Möglichkeit, das Leuchtdichteverhältnis bei der Montage der Anlage oder bei einer erforderlich werdenden Anpassung an geänderte Raumbedingungen, worunter Umstellungen oder Austausch des Mobiliars oder der Arbeitsgerätschaften sowie andere Anstrahlbedingungen für die Decke fallen, durch einfache und leicht zu betätigende Mittel in kürzester Zeit zu ändern.It has been shown that one can with the currently available lighting systems for direct and indirect lighting is not able to achieve a desired or Required luminance ratio, as set out above, when installing the system or when the purpose of a room equipped with lights is changed to achieve without difficulty. At least so far there has been no way the luminance ratio when installing the system or when it is required adapting to changed room conditions, including changes or exchanges the furniture or work equipment as well as other lighting conditions for the ceiling will fall by simple and easy-to-use means in no time to change.

Durch Sie Erfindung werden die bestehenden Schwierigkeiten behoben, und es wird durch sie der Weg zu einer auSbau- und bediennngsmäßigen Vervollständigung offenl7art, die den bekannten Anlagen ermangelt. Die Erfindung, welche von Beleuchtungsanlagen für direkte und indirekte Beleuchtung ausgeht, besteht in ihrem Grundprinzip darin, daß die Leuchtenreflektoren Lichtdurchtrittsöffnungen aufweisen, und daß diesen Lichtdurchtrittsöffnungen verstellbare Blenden zugeordnet sind.Through your invention, the existing difficulties are resolved, and through them it becomes the way to an expansion and operational completion open, which the known systems lack. The invention, which of lighting systems for direct and indirect lighting, its basic principle is to that the light reflectors have light passage openings, and that these Light passage openings are assigned to adjustable diaphragms.

In Fällen, wo eine diffuse oder gestreute Aufhellung der Decke oder von Deckenpartien wünschenswert erscheint, sind nach einem weiteren Merkmal der Erfindung hinter den blendenbewehrten Lichtdurchtrittsöffnungen Diffusor- oder Prismenplatten angeordnet.In cases where a diffuse or scattered lightening of the ceiling or of ceiling parts appears desirable, are according to a further feature of the Invention behind the visor-reinforced light passage openings diffuser or prismatic plates arranged.

Die Erfindung wird an Hand von in den Fig. 1 und 2 dargestellten Ausführungsbeispielen näher erläutert. Dabei zeigt Fig. 1 die Verwirklichung des Grundprinzips der Erfindung an einem üblichen Leuchtentyp, während Fig. 2 den Einbau einer mit Blende(n) erfindungsgemäß ausgestatteten Leuchte in einer liasterdecke zum Gegenstand hat.The invention is illustrated by the embodiments shown in FIGS explained in more detail. 1 shows the implementation of the basic principle of the invention on a conventional type of luminaire, while FIG. 2 shows the installation of a cover (s) according to the invention equipped luminaire in a laster ceiling.

In Fig. 1 ist mit 1 der Reflektor einer mit Lichtquelle 2 versehenen Leuchte bezeichnet, wobei der Reflektor Lichtdurchtrittsöffnungen 3, 4 aufweist, denen einstellbare Blenden 5, 6 zugeordnet sind. Mit 7, k3 sind der Leuchte untergehängte Rasterelemente angedeutet, die Blendwirkungen verhindern sollen. 9 ist eine Diffusorplatte, mittels deren das durch die Lichtdurchtrittsöffnung 3 gelangte Licht zerstreut werden kann, bevor es die Decke 10 beaufschlagt.In Fig. 1, the reflector 1 is provided with a light source 2 Designated luminaire, the reflector having light passage openings 3, 4, which adjustable apertures 5, 6 are assigned. With 7, k3 the lamp is suspended Grid elements indicated that are intended to prevent the effects of glare. 9 is a diffuser plate, by means of which the light that has passed through the light passage opening 3 is scattered can before it acts on the ceiling 10.

Wie man sieht, wird der hauptsächliche Anteil der Strahlen der Lichtquelle 2 nach unten reflektiert, während ein klein durch die Blenden 5, 6 einstellbarer Anteil nach oben zur Decke austritt, wo er die indirekte Beleuchtung-herstellt. Die Dlenden sind in nichtdargestellten Lagern geführt, und sie sind mit Handhaben o.dgl. versehen, die es erlauben, jede Blende am Ort der eingebauten oder an der Decke angehängten Leuchte so zu verstellen , daß ein gewünschtes Leuchtdichteverhältnis zwischen Decke und Raum (Arbeitsfläche) erzielt ist.. Die Blenden können auch als Lochblenden ausgeführt sein, falls sich dies als zweckmäßig erweisen sollte.As you can see, the main part of the rays becomes the light source 2 reflected downwards, while a small one can be adjusted by means of the apertures 5, 6 Share exits upwards to the ceiling, where it produces the indirect lighting. The diaphragms are guided in bearings (not shown) and they come with handles or the like. provided that allow each panel to be installed at the location of the built-in or at the To adjust the ceiling-attached lamp so that a desired luminance ratio between the ceiling and the room (work surface) is achieved. The panels can also be used as Perforated diaphragms should be designed if this should prove to be expedient.

Bei der in Fig. 2 dargestellten Leuchte, welche in eine vorgefertigte Decke 11 mit Rastern, wie bei 12, 13 angedeutet, eingebaut ist, sind bei diesem Ausführungsbeispiel im Reflektor 1 im ganzen drei Lichtdurchtrittsöffnungen 14 bis 16 vorgesehen, die mit zugehörigen Verstellblenden 17 bis 19 versehen sind. Es gelingt hierdurch, sowohl die zur Decke 11 strahlenden, als auch zu den Rasterseitenflächen gelangenden Lichtanteile so zu regeln, daß alle innerhalb sinnvoller Grenzen erwünschten Leuchtdichteverhältnisse erreicht werden können. Auch hier gilt, daß der maximale Lichtanteil nach unten, zur Nutzebene N hin, gelangen soll. Mit B ist die Aufhängehöhe der Leuchte über N bezeichnet. N befindet sich 0,85 m über dem Fußboden, also in einer Ilöhe, auf die die Nennbeleuchtungfistärke bezogen wird.In the lamp shown in Fig. 2, which in a prefabricated Ceiling 11 with grids, as indicated at 12, 13 is installed, are in this Embodiment in the reflector 1 a total of three light passage openings 14 to 16 provided, which are provided with associated adjustment panels 17 to 19. It succeeds As a result, both the radiating to the ceiling 11 and the grid side surfaces to regulate incoming light components so that all desired within reasonable limits Luminance ratios can be achieved. Here, too, the maximum Light component should go down, to the useful level N. With B is the suspension height of the lamp above N. N is 0.85 m above the floor, i.e. in an Iheight to which the nominal illuminance is related.

Die Erfindung bietet den großen Vorteil, daß sowohl bei der Montage als auch bei mit Leuchten bereits versehenen Räumen an Ort und Stelle erforderliche oder gewünschte Leuchtdichteverhältnisse oder Kontrastvorstellungen einfach durch Verstellen von Blenden erzielt werden können, was, technisch und aufbaumäßig gesehen, mit geringem Aufwand und, bedienungsmäßig betrachtet, schnell und ohne jede Schwierigkeit durchfütirbar ist.The invention offers the great advantage that both during assembly as well as in rooms already equipped with lights on the spot or the desired luminance ratios or ideas of contrast Adjustment of panels can be achieved, which, technically and structurally, with little effort and, in terms of operation, quickly and without any difficulty is feasible.

Man kann mit der Leuchte der Erfindung optimal nur 8o viel Licht wie erforderlich zur Deckenaufhellung gegen die Decke strahlen und die Leuchte möglichst weit nach unten und damit verlustäraer in die Nutzebene wirken lassen.With the lamp of the invention you can optimally only get 8o much light like required to illuminate the ceiling and shine the luminaire against the ceiling if possible let it work far down and thus in the usable plane.
