Abstract
Description
Die Erfindung betrifft eine Leuchte für langgestreckte Leuchtmittel, wie z.B. Leuchtstofflampen, mit zumindest einem gekrümmten Reflektor, in dessen stärkstem Krümmungsbereich das langgestreckte Leuchtmittel positioniert ist, und mit einer Leuchtmittelfassung und einer dem Leuchtmittel zugeordneten Abblendeinheit, die aus mehreren Rasterflächen aus lichtdurchlässigem Material besteht, die beidseits des Leuchtmittels angeordnet sind.The invention relates to a lamp for elongated lamps, such as e.g. Fluorescent lamps, with at least one curved reflector, in the strongest area of curvature positions the elongated lamp is, and with a bulb holder and the bulb associated dimming unit, which consists of several grid areas translucent material, which is arranged on both sides of the lamp are.
Eine Leuchte dieser Art ist bekannt aus der DE 41 25 545 A1. Bei dieser bekannten Leuchte ist die Leuchtstofflampe über ihre Länge innerhalb eines einen vierseitigen geschlossenen Querschnitt aufweisenden Lampenkanals angeordnet, wobei die Oberseite dieses Lampenkanals von einem Reflektorbereich und die Unterseite des Lampenkanals von einem Hilfsreflektor gebildet sind, während die Seitenwände des Lampenkanals aus Prismenplatten aus transparentem Material bestehen, die zum einen in Längsrichtung und zum andern in Querrichtung des Lampenkanals verlaufen.A lamp of this type is known from DE 41 25 545 A1. At this Known lamp is the fluorescent lamp over its length within a a four-sided closed cross-section lamp channel arranged, the top of this lamp channel by a Reflector area and the underside of the lamp channel by an auxiliary reflector are formed, while the side walls of the lamp channel Prismatic plates made of transparent material, which on the one hand in Run longitudinally and secondly in the transverse direction of the lamp channel.
Des weiteren ist eine vergleichbare Leuchte bekannt aus der EP 0 538 727 A1. Bei dieser Leuchte ist als Abblendeinheit bzw. Blendschutz ein halbzylindrisch ausgebildetes Lochblech vorgesehen, das das außerhalb der Öffnungsebene des Gehäuses gelegene Leuchtmittel umschließt. Die Innen- und/oder Außenseite des Lochblechs ist mit einer lichtdurchlässigen Folie abgedeckt, wobei Lochblech und Folie zusammen einen Ersatz für opake oder milchige Halbschalen bilden sollen. A comparable luminaire is also known from EP 0 538 727 A1. This lamp is a semi-cylindrical as anti-glare unit or anti-glare protection trained perforated plate provided that the outside of Illuminant located in the opening plane of the housing. The interior and / or outside of the perforated plate is with a translucent Foil covered, perforated sheet and foil together a replacement for should form opaque or milky half-shells.
Aufgabe der Erfindung ist es, eine Leuchte der eingangs angegebenen Art so auszugestalten, daß die Verwendung eines möglichst flachen, d.h. eine geringe Tiefe aufweisenden Gehäuses ermöglicht und unter Ausschaltung störender Blendeffekte eine optimale Lichtausnutzung bei möglichst gleichmäßiger Leuchtdichte über die gesamte Öffnungsfläche der Leuchte erhalten wird.The object of the invention is to provide a lamp of the type specified To be designed so that the use of a flat, i.e. a low-depth housing allows and with switching off annoying glare effects optimal use of light with as much as possible uniform luminance over the entire opening area of the lamp is obtained.
Gelöst wird diese Aufgabe nach der Erfindung im wesentlichen dadurch, daß der gekrümmte Reflektor, die Leuchtmittelfassung und die Abblendeinheit in einem flachwannenförmigen Gehäuse gehaltert sind und sich der Reflektor über die gesamte Grundfläche des Gehäuses und bis zu zwei einander gegenüberliegenden Rändern in der Öffnungsebene des Gehäuses erstreckt, daß die Rasterflächen der Abblendeinheit aus gegenseitig beabstandetem, zueinander parallelen und parallel zum Leuchtmittel verlaufenden Rasterflächen besteht, die sich zumindest zum Teil über die Öffnungsfläche des Gehäuses nach außen erstrecken und durch zumindest einen ebenfalls aus lichtdurchlässigem Material bestehenden Quersteg miteinander verbunden sind. According to the invention, this object is essentially achieved by that the curved reflector, the bulb holder and the dimming unit are held in a flat trough-shaped housing the reflector over the entire base of the housing and up to two opposite edges in the opening plane of the housing extends that the grid areas of the dimming unit from each other spaced, parallel to each other and parallel to the illuminant Grid areas exist that are at least partially over the Extend opening area of the housing to the outside and through at least a crossbar also made of translucent material are interconnected.
Durch die Verwendung von Rasterflächen aus lichtdurchlässigem Material, insbesondere aus Kunststoffmaterial, ist es möglich, einerseits die erforderliche Vergleichmäßigung der Leuchtdichte zu erreichen und andererseits den seitlichen Lichtverlust zu minimieren, so daß eine maximale Lichtnutzung erreicht wird. Besonders vorteilhaft ist dabei, daß die an den Rasterflächen vorhandene Rasterung praktisch nicht in Erscheinung tritt, und zwar auch nicht bei seitlicher Blickrichtung auf die Leuchte, weil sich das Licht in den aus Kunststoff oder Glas bestehenden Rasterflächen gleichmäßig verteilt und damit auch diejenigen Bereiche der Abblendeinheit eine entsprechend angepaßte Leuchtdichte besitzen, welche nicht direkt vom Leuchtmittel beaufschlagt werden.By using grid surfaces made of translucent It is material, especially plastic material possible, on the one hand, the necessary equalization of the To achieve luminance and the other side Minimize light loss so that maximum light usage is achieved. It is particularly advantageous that the grid on the grid surfaces is practical does not appear, not even from the side Looking at the lamp because the light is in the grid surfaces made of plastic or glass evenly distributed and thus also those areas of the Dimming unit have a correspondingly adjusted luminance, which is not directly affected by the lamp become.
Die an den Rasterflächen vorgesehene Rasterung wird bevorzugt durch Strangpressen hergestellt, wobei unterschiedliche Querschnittsstrukturen der dabei gebildeten Rippen und Vertiefungen realisiert werden können. In einem ersten Vorgang mit durchgehenden Rippen gefertigte Rasterungen können durch einen weiteren Bearbeitungsschritt, insbesondere durch einen weiteren Preßschritt derart modifiziert werden, daß Einzelelemente, zum Beispiel in Form von Einzelpyramiden, geschaffen werden, wenn eine derartige Rasterstruktur gefordert wird.The grid provided on the grid areas is preferred made by extrusion, being different Cross-sectional structures of the ribs and depressions formed can be realized. In a first process Screenings made with continuous ribs can be made by a further processing step, in particular by a further pressing step are modified such that individual elements, for example in the form of individual pyramids if such a grid structure is required becomes.
Grundsätzlich ist es auch möglich, von einer Rasterung, das heißt der Verwendung einer Prismatikstruktur Abstand zu nehmen, wenn beispielsweise leicht eingefärbte, opake Kunststoffe als Abblendelemente vorgesehen werden, wie dies für bestimmte Anwendungsfälle durchaus möglich ist.Basically, it is also possible from a grid that means to refrain from using a prismatic structure, if, for example, slightly colored, opaque plastics be provided as anti-glare elements, as is the case for certain use cases is quite possible.
Die Rasterflächen sind bevorzugt parallel zueinander angeordnet und durch ebenfalls lichtleitende Querstege miteinander verbunden, so daß kompakte Einheiten entstehen, bei denen die Anzahl der zueinander parallelen Rasterflächen in Abhängigkeit davon gewählt wird, welche Leuchtdichte in Anpassung an die Reflektorleuchtdichte an den außenliegenden Rasterflächen gefordert wird.The grid areas are preferably arranged parallel to one another and with each other through light-conducting crossbars connected so that compact units arise in which the number of parallel grid areas depending of which is chosen, which luminance in adaptation the reflector luminance on the outside grid surfaces is required.
Die aus Kunststoff oder Glas bestehenden Rasterflächen sind auf ihrer dem Leuchtmittel zugewandten Seite glatt und auf ihrer vom Leuchtmittel abgewandten Seite vorzugsweise geriffelt ausgebildet, da durch diese so geschaffene Prismatik unter Vermeidung von Blendeffekten der Lichtverlust sehr gering ist und damit durch Anordnung mehrerer solcher Rasterflächen eine sehr gezielte und definierte Leuchtdichtenabstimmung ermöglicht wird.The grid surfaces are made of plastic or glass on its side facing the illuminant smooth and open their side facing away from the lamp preferably corrugated trained, because of this prismatic very little loss of light while avoiding glare and thus by arranging several such grid areas a very targeted and defined luminance adjustment is made possible.
Von wesentlicher Bedeutung ist im Rahmen der Erfindung auch, daß die einzelnen Reflektorflächen asymmetrisch gekrümmt ausgebildet sind, und zwar derart, daß der Bereich der stärksten Krümmung sich dort befindet, wo das Leuchtmittel angeordnet ist, so daß das Leuchtmittel im Brennpunktbereich oder unmittelbar benachbart dem jeweiligen Brennpunktbereich gelegen ist. Dies schafft in Verbindung mit den jeweiligen Abblendeinheiten auch die Möglichkeit, einerseits über den Reflektor eine gute Ausbeute an indirektem Licht zu erzielen und andererseits einen vorgebbaren Direktlichtanteil zu nutzen.In the context of the invention, it is also essential that that the individual reflector surfaces are asymmetrically curved are such that the area is the strongest Curvature is where the lamp is placed is, so that the illuminant in the focal area or immediately adjacent to the respective focus area is located. This creates in connection with the respective Dimming units also have the option of using the Reflector to achieve a good yield of indirect light and on the other hand to use a predeterminable proportion of direct light.
Durch die Anordnung des Leuchtmittels im Innenraum des wannenförmigen Gehäuses und die flache Struktur der asymmetrischen Einzelreflektoren wird eine sehr kompakte und flache Bauweise gewährleistet, die zu vergleichsweise großflächigen Leuchten mit gleichmäßiger Lichtdichte führt, die alle Anforderungen hinsichtlich Blendungsfreiheit und optimaler Lichtausnutzung erfüllen.By arranging the lamp in the interior of the trough-shaped Housing and the flat structure of the asymmetrical Single reflectors becomes a very compact and flat Design guaranteed, which is comparatively large Luminaires with uniform light density that meet all requirements with regard to freedom from glare and optimal use of light fulfill.
Durch Kombination von erfindungsgemäßen Leuchten mit gleicher oder unterschiedlicher Abstrahlcharakteristik und Vorgabe bestimmter Abstände bei der Montage dieser Leuchten ist es möglich, für den jeweiligen Einsatzzweck optimale Lichtverteilungskurven zu erzielen, wobei es problemfrei möglich ist, eine gesamte Raumfläche gleichmäßig auszuleuchten, bestimmte Bereiche des jeweiligen Raumes, insbesondere die Raummitte, bevorzugt zu beleuchten oder beispielsweise in bestimmten Bereichen des Raumes, insbesondere im Zentrum des Raumes, einen reflexfreien Bereich zu schaffen und die Randbereiche stärker auszuleuchten.By combining lights according to the invention with the same or different radiation characteristics and specifications certain distances when installing these lights it is possible to have optimal light distribution curves for the respective application to achieve, it being possible without problems is to illuminate an entire area evenly, certain Areas of the respective room, especially the Center of the room, preferably to illuminate or for example in certain areas of the room, especially in the center of the room Space to create a reflection-free area and the peripheral areas illuminate more.

Figur 1 zeigt ein in Form einer flachen Wanne ausgebildetes Rechteckgehäuse 1 mit einem Gehäuseboden 2 und Seitenwänden 3, das an einer Decke befestigt werden kann, vorzugsweise aber in eine Decke, insbesondere Rasterdecke eingebaut bzw. integriert wird.Figure 1 shows a formed in the form of a flat trough Rectangular housing 1 with a housing base 2 and side walls 3, which can be attached to a ceiling, preferably but built into a ceiling, especially grid ceiling or integrated.
Der Öffnungsquerschnitt des Gehäuses 1 ist mit der Bezugsziffer
4 gekennzeichnet, und im Innenraum 15 des Gehäuses 1
sind sowohl die Reflektoren 5, 6 als auch das Leuchtmittel 8
mit zugehöriger Abblendeinheit 14 untergebracht, wobei sich
die Abblendeinheit 14 zumindest zum Teil über die Öffnungsfläche
4 des Gehäuses hinaus erstreckt.The opening cross section of the housing 1 is with the reference number
4 marked, and in the
Die beiden Reflektoren 5, 6 erstrecken sich über den gesamten
Gehäusequerschnitt und sind mittensymmetrisch angeordnet,
so daß durch die beiden Reflektoren 5, 6 eine Art Flügelstruktur
entsteht. Im Bereich der Außenränder der einander
gegenüberliegenden Seitenwände 3 des Gehäuses sind die
Reflektoren 5, 6 bündig befestigt und weisen nur eine sehr
schwache Krümmung auf. Die Krümmung nimmt zur Mitte des Gehäuses
1 hin zu, wobei die Reflektoren 5, 6 der Mitte benachbart
vorzugsweise am Gehäuseboden 2 anliegen und dann mit
stärkerer Krümmung zur Mitte hin weitergeführt sind, wo sie
sich in einer Verbindungskante 7 treffen, die in der oberen
Hälfte des Innenraumes 15 des Gehäuses 1 gelegen ist.The two
Unmittelbar benachbart dieser Verbindungskante 7 und ebenfalls
mittensymmetrisch angeordnet befindet sich das Leuchtmittel
bzw. die Leuchtstofflampe 8, die im Falle einer einseitig
gesockelten Lampe in einer Fassung 13 gehaltert ist,
die an einer Seitenwand 3 angebracht ist.Immediately adjacent to this connecting edge 7 and also
the illuminant is arranged in a symmetrical manner
or the
Dem Leuchtmittel 8 zugeordnet und diesem Leuchtmittel 8 unmittelbar
benachbart angeordnet ist eine Abblendeinheit 14,
die von mehreren aus Glas oder Kunststoff bestehenden Rasterflächen
9 gebildet ist. Diese Rasterflächen 9 werden über
Querstege 10 aus dem gleichen Material zusammengehalten und
erstrecken sich senkrecht zum Gehäuseboden 2 etwa von der
Mitte des Innenraums 15 des Gehäuses 1 nach außen. Die Rasterflächen
9 verlaufen parallel zueinander und haben zur
Ausbildung einer stufigen Struktur unterschiedliche Längen.
Auf diese Weise lassen sich auch blickwinkelbezogen unterschiedliche
Abblendeffekte erzielen, und zwar im Hinblick
auf die angestrebte gleichförmige Leuchtdichte über den gesamten
Öffnungsquerschnitt 4.Associated with the
In dem freien Mittelraum zwischen den beiden seitlich des
Leuchtmittels 8 gelegenen Rasterflächen ist ein offenes
Raster 11 angebracht, so daß wiederum unter Ausschaltung von
Blendeffekten in diesem Mittelbereich eine Direktabstrahlung
erreicht wird, während reflektorseitig eine optimale Lichteinstrahlung
auf die Reflektoren 5 und 6 erzielt wird. Bei
dem offenen Raster 11 kann es sich um ein Quadrat-, Rechteck-
oder Rundraster handeln, das bevorzugt aus lichtdurchlässigem
Material, insbesondere Kunststoffmaterial, hergestellt
ist.In the free space between the two on the side of the
Luminous 8 grid areas is an open
Grid 11 attached, so that again with the exclusion of
Glare effects in this central area direct radiation
is achieved while optimal light irradiation on the reflector side
is achieved on the
Die Abblendeinheit 14 ist dabei gleichzeitig als Träger für
das offene Raster 11 genutzt, wobei zwischen diesen beiden
Einheiten eine Schiebeführung, Schnapp-Rast-Verbindungen
oder eine sonstige Klemmverbindung vorgesehen sein kann.The
Die Ausführungsvariante nach Figur 2 zeigt eine mittensymmetrische Leuchte mit zwei voneinander getrennt angeordneten Leuchtmitteln 8 in einem gemeinsamen Gehäuse 1. Es ist darauf hinzuweisen, daß es im Rahmen der Erfindung einer weiteren Ausführungsform entspricht, wenn in einem Gehäuse 1 nur eine einzige derartige Reflektoreinheit vorgesehen ist, da dann eine Anordnung vorliegt, bei der die Mittelebene der Leuchte nach Figur 2 durch eine Seitenwand 3 ersetzt werden würde.The embodiment variant according to FIG. 2 shows a center symmetrical one Luminaire with two separately arranged Illuminants 8 in a common housing 1. It is on it to point out that it is within the scope of the invention another Embodiment corresponds if only in a housing 1 a single such reflector unit is provided because then there is an arrangement in which the median plane of the 2 are replaced by a side wall 3 would.
Bei der Ausführungsform nach Figur 2 sind die beiden wiederum
asymmetrisch ausgebildeten Reflektoren 5, 6 mittig bis
zur Öffnungsfläche 4 des Gehäuses 1 nach vorne gezogen, das
heißt die Verbindungskante 7 liegt etwa im Bereich des Öffnungsquerschnitts
der Leuchte.In the embodiment according to FIG. 2, the two are again
asymmetrically designed
Die Leuchtmittel 8 sind etwa in den Brennpunktbereichen der
Reflektoren gelegen, und die jeweils zugehörige Abblendeinheit
ist so ausgebildet und positioniert, daß sich wiederum
die angestrebte direkte und indirekte Lichtabstrahlung ergibt
und eine ausgeglichene Leuchtdichtenverteilung erzielt
wird.The
Die aus Glas oder Kunststoff bestehenden Rasterflächen 9 verlaufen
etwa unter einem Winkel von 45° zur Bodenfläche 2 des
Gehäuses und erstrecken sich nur geringfügig über die Öffnungsfläche
4 hinaus. Die zueinander parallelen Rasterflächen
9 sind durch Querstege 10 miteinander verbunden, und an
die kürzeste, zur Gehäusemitte hin gelegene Rasterfläche 9
ist eine dazu senkrecht verlaufende weitere Rasterfläche
angeformt, die sich bis in die Nähe des jeweiligen Reflektors
5, 6 erstreckt, jedoch bezüglich des jeweiligen Reflektors
einen Spalt offenläßt. Durch diese Abblendeinheit wird
ein direkter Sichtkontakt zum jeweiligen Leuchtmittel 8 ausgeschlossen
und sichergestellt, daß über die gesamte Leuchtenfläche
eine sehr gleichmäßige Leuchtdichte erzielt wird.The
Durch die Ausgestaltung und Relativanordnung von Leuchtmittel
8, Reflektoren 5, 6 und Abblendeinheit 14 treten in der
Leuchte nur sehr geringe Luftströmungen auf, was zur Folge
hat, daß störende Schmutzablagerungen am Reflektor oder an
den Reflektoren vermieden werden können. Due to the design and relative arrangement of
Figur 3 zeigt in schematischer Weise die Lichtverteilungskurve einer Leuchtenanordnung gemäß Figur 2. Die auf diese Weise realisierte Lichtverteilung eignet sich vor allem für diejenigen Fälle, bei denen die Mitte des jeweiligen Raumes bevorzugt beleuchtet werden soll und im Wandbereich wenig Licht erwünscht ist, wie dies zum Beispiel bei Räumen mit Glasfassaden der Fall ist.Figure 3 shows the light distribution curve in a schematic manner a lamp arrangement according to Figure 2. The on this Realized light distribution is particularly suitable for those cases where the middle of each room should preferably be illuminated and little in the wall area Light is desired, such as in rooms with Glass facades is the case.

Durch entsprechende Positionierung dieser Leuchten und Kombination mit eine gleichartige oder auch unterschiedliche Lichtverteilungskurve besitzenden weiteren Leuchten lassen sich an die individuellen Gegebenheiten anpaßbare Raumausleuchtungen erzielen.Figure 4 shows a light distribution curve with the base unit the double arrangement shown in Figure 2 achievable is. By appropriate positioning of these lights and Combination with a similar or different Let light distribution curve have other lights Room lighting that can be adapted to individual circumstances achieve.
Figur 5 zeigt eine Lichtverteilungskurve einer erfindungsgemäßen Doppelleuchte, die geeignet ist, über einen größeren Raumbereich einen höheren Lichtbedarf zu decken. Werden beispielsweise zwei derartige Leuchten mit gegenseitigem Abstand spiegelsymmetrisch zur Raummitte angeordnet, so ist es möglich, den mittleren Bereich der Decke des Raumes relativ dunkel und ruhig zu belassen, während in der Mitte des Raumes ein geforderter höherer Lichtbedarf gedeckt werden kann, während gleichzeitig die Raumwände aufgrund der vorhandenen Abstrahlcharakteristik relativ dunkel bleiben können.Figure 5 shows a light distribution curve of an inventive Double lamp that is suitable for a larger one Area to cover a higher light requirement. For example two such lights with a mutual distance It is arranged in mirror symmetry to the center of the room possible the relative area of the ceiling of the room relative leave dark and calm while in the middle of the room a required higher light requirement can be met, while at the same time the room walls due to the existing Radiation characteristics can remain relatively dark.
Die schematische Darstellung nach Figur 6 zeigt das Zusammenwirken zweier Leuchten mit der in Figur 4 gezeigten Lichtverteilungskurve. In diesem Falle ist es möglich, die Wände des Raumes hell zu beleuchten, wie dies beispielsweise für Repräsentationsräume gewünscht wird. Durch das in Figur 6 gezeigte Zusammenwirken der erfindungsgemäßen Leuchten ist es aber vor allem möglich, ein praktisch reflexionsfreies Zentrum im Raum zu schaffen, was die Aufstellung von Bildschirmen erleichtert und gute Arbeitsbedingungen unter beleuchtungstechnischen Aspekten schafft.The schematic representation according to FIG. 6 shows the interaction two lights with the light distribution curve shown in Figure 4. In this case it is possible to remove the walls to illuminate the room brightly, such as for Representative rooms is desired. By the in Figure 6 shown interaction of the lights of the invention but above all it is possible to have a practically reflection-free Center in the room to create what the placement of screens facilitated and good working conditions under lighting technology Creates aspects.
Werden höhere Beleuchtungsstärken gefordert, so können anstelle der in Figur 6 gezeigten Einzelanordnungen auch Doppelleuchten von der in Figur 5 gezeigten Art eingesetzt werden.If higher illuminance levels are required, instead of of the individual arrangements shown in FIG. 6 also double lights of the type shown in Figure 5 can be used.
Durch die anhand der Figuren 3 bis 6 erläuterten Beispiele wird deutlich, daß durch die gemäß der Erfindung gestalteten Leuchten, und insbesondere durch Kombination gleichartiger oder auch verschiedener Ausführungsformen, die in der Praxis vorkommenden Beleuchtungsaufgaben optimal gelöst werden können, da je nach bestehender Forderung sowohl gleichmäßige Raumausleuchtungen als auch differenzierte Raumausleuchtungen realisiert werden können und dabei stets dem jeweiligen Lichtbedarf Rechnung getragen werden kann. Through the examples explained with reference to FIGS. 3 to 6 it is clear that by the designed according to the invention Luminaires, and especially by combining similar ones or even different embodiments that are in practice existing lighting tasks can be optimally solved, because depending on the existing requirement, both uniform Room lighting as well as differentiated room lighting can be realized and always the respective Light requirements can be taken into account.
