Abstract

The light has one or more lamps (7) and an at least partly transparent first screen (1) via which light passes downwards in the operating position. A second transparent screen (15) is mounted in the light path between the first screen and the lamp or lamps at a distance from the first screen. The second screen essentially consists of a clear foil.

Description

Die Erfindung betrifft eine Leuchte, insbesondere eine abhängbare Deckenleuchte oder eine Deckeneinbauleuchte, gemäß dem Oberbegriff des Anspruchs 1. Bei einer bekannten Deckenleuchte ist die Lampe in einer Rinne aus einem Lochblech aufgenommen, über der ein Sekundärreflektor angeordnet ist, der das nach oben abgestrahlte Licht nach unten in den Raum reflektiert. Um einen gleichmäßigen Helligkeitseindruck zu erhalten, ist das Lochblech mit einer weißen Folie hinterlegt. Die nicht gleichmäßige Ablagerung von Schmutz in der Rinne (z.B. Insekten) führt zu deutlich sichtbaren dunklen Flecken in der Rinne, die eine häufige Reinigung durch den Benutzer erfordern.The invention relates to a luminaire, in particular a suspended ceiling lamp or a ceiling luminaire, according to the preamble of claim 1. In a known ceiling lamp, the lamp is received in a groove of a perforated plate, on which a secondary reflector is arranged, which after the upwardly radiated light after reflected down into the room. To obtain a uniform impression of brightness, the perforated plate is covered with a white foil. The non-uniform deposition of soil in the gutter (e.g., insects) results in clearly visible dark spots in the gutter that require frequent cleaning by the user.

Zur Lösung dieses Problems wurde bislang vorgeschlagen, ein feines Maschengitter, z.B. aus Stahl, zwischen der Lampe und dem Lochblech anzuordnen. Das vorangehend skizzierte Verschmutzungsproblem wird dadurch jedoch nicht vollständig gelöst, da Insekten teilweise auch noch durch relativ kleine Löcher durchfallen oder kriechen. Ein derartiges Gitter hat außerdem den Nachteil, daß es nicht einfach zu reinigen ist und, wenn es hinreichend feinmaschig ist, die Lichttransmission deutlich behindert.To solve this problem, it has hitherto been proposed to use a fine mesh, e.g. steel, between the lamp and the perforated plate. However, the pollution problem outlined above is not completely solved as insects sometimes also fall through or creep through relatively small holes. Such a grid also has the disadvantage that it is not easy to clean and, if it is sufficiently fine mesh, the light transmission significantly impeded.

In der gattungsbildenten US 4 833 575 wird ein Lichtfiltersystem zur Helligkeitsangleichung offenbart, welches ein Gehäuse mit Reflektoren, einen lichtdurchlässigen unteren Schirm und einen zwischen einer Lampe und dem unteren Schirm angeordneten lichtdurchlässigen oberen Schirm aufweist, wobei der obere Schirm aus einer lichtdurchlässigen Platte mit einem darauf aufgebrachten lichtundurchlässigen Muster besteht, welches den Lichtdurchtritt durch diesen Schirm selektiv verhindert, um die Intensität des hindurchtretenden Lichts zu vergleichmäßigen. Dieses Muster wird durch eine Metallschicht gebildet, welche gleichzeitig als Masse für die Zündvorrichtung der Lampen dient und darüber hinaus Licht, welches nicht durchgelassen wird, in den Raum oberhalb des oberen Schirms zurückreflektiert.In the generic US 4,833,575 discloses a light filtering system for brightness equalization, comprising a housing with reflectors, a translucent lower screen and a translucent upper screen disposed between a lamp and the lower screen, the upper screen consisting of a translucent plate having an opaque pattern applied thereto, which comprises the Light transmission through this screen selectively prevented to even out the intensity of the transmitted light. This pattern is formed by a metal layer, which at the same time serves as the ground for the lighting device of the lamps and, moreover, reflects light which is not transmitted back into the space above the upper screen.

In DE 92 13 886 U ist ein Reflektor für eine Leuchte mit wenigstens einem langgestreckten Leuchtmittel bzw. wenigstens einer Lampe beschrieben, wobei der Reflektor das oder die Leuchtmittel wenigstens teilweise überdeckt und aus einem Lochblech gefertigt ist und an dem Lochblech innen und/oder außen eine lichtdurchlässige Folie anliegt.In DE 92 13 886 U a reflector for a luminaire is described with at least one elongate luminous means or at least one lamp, wherein the reflector or the Illuminant is at least partially covered and made of a perforated plate and on the perforated plate inside and / or outside a translucent film is applied.

In GB 2 215 447 A ist eine Leuchte offenbart, welche eine lichtdurchlässige Abdeckung aufweist, die Licht teilweise reflektiert und teilweise durchläßt und in einer Ausführungsform aus einem Lochblech besteht, das mit einem lichtdurchlässigen Gewebe verkleidet ist, das eine geeignete Kombination von Lichtdurchlässigkeit und Reflektivität aufweist.In GB 2 215 447 A there is disclosed a luminaire having a translucent cover which partially reflects and partially transmits light, and in one embodiment consists of a perforated sheet clad with a translucent fabric having a suitable combination of translucency and reflectivity.

Es ist die Aufgabe der Erfindung, eine Leuchte gemäß dem Oberbegriff des Anspruchs 1 zur Verfügung zu stellen, bei der tote Insekten und dgl. von dem ersten Schirm, wo sie sich optisch deutlich bemerkbar machen, zuverlässig mit geringen Lichtverlusten zurückgehalten werden.It is the object of the invention to provide a luminaire according to the preamble of claim 1, in which dead insects and the like are reliably retained with low light losses from the first screen, where they make themselves clearly noticeable.

Dieses Problem wird erfindungsgemäß gelöst durch eine Leuchte, insbesondere durch eine Deckenleuchte, mit einer oder mehreren Lampen, die von außen in einer Weise zugänglich sind, daß Schmutz oder Insekten in den Bereich der Lampen eindringen kann, sowie einem zumindest teilweise lichtdurchlässigen ersten Schirm, durch den im Gebrauchszustand der Leuchte Licht nach unten abgegeben wird, welche dadurch gekennzeichnet ist, daß in dem Lichtweg zwischen dem ersten Schirm und der Lampe oder den Lampen ein zweiter Schirm, der aus einem klaren oder Licht streuenden lichtdurchlässigen Material besteht, von dem ersten Schirm beabstandet angeordnet ist. Die Leuchte kann dabei insbesondere eine Deckeneinbauleuchte, eine Anbauleuchte, eine Pendelleuchte oder eine Stehleuchte sein.This problem is inventively solved by a lamp, in particular by a ceiling light, with one or more lamps, which are accessible from the outside in a way that dirt or insects can penetrate into the area of the lamps, as well as an at least partially translucent first screen by is given down in the use state of the lamp light, which is characterized in that in the light path between the first screen and the lamp or the lamps, a second screen, which consists of a clear or light-scattering translucent material, from the first Screen is arranged spaced. The luminaire can be in particular a recessed ceiling luminaire, a surface-mounted luminaire, a pendant luminaire or a floor lamp.

Dabei ist der zweite Schirm so montiert, daß er im Gebrauchszustand zumindest für den Bereich der unmittelbaren Umgebung der Lampen verhindert, daß tote Insekten, Schmutzpartikel oder dgl. aus diesem Bereich auf den ersten Schirm fallen.In this case, the second screen is mounted so that it prevents in use, at least for the area of the immediate vicinity of the lamps that dead insects, dirt particles or the like. Fall from this area on the first screen.

Die Erfindung ist insbesondere bei solchen Lampen einsatzbar, die eine nach außen weisende Öffnung zu dem Lampenbereich aufweisen, insbesondere solchen, welche im Gebrauchszustand eine nach oben gerichtete Öffnung aufweisen oder bei der die Lampe bzw. Lampen nach oben nicht abgeschirnt sind.The invention is particularly applicable to such lamps having an outwardly facing opening to the lamp area, in particular those which have an upward opening in use or in which the lamp or lamps are not abgeschirnt upwards.

Der zweite Schirm kann aus einem klaren Material, insbesondere aus einer klaren, vorzugsweise formstabilen Folie bestehen- In der Regel sorgt der Abstand zwischen dem ersten Schirm und dem zweiten Schirm bereits dafür, daß sich von dem zweiten Schirm zurückgehaltene Partikel nicht oder jedenfalls nicht scharf auf dem ersten Schirm abbilden. Zur besseren Maskierung kann vorgesehen sein, daß der zweite Schirm zumindest teilweise diffus streuend ausgebildet ist. Auch bei dieser Ausführungsform kann der zweite Schirm im wesentlichen durch eine vorzugsweise formstabile Folie gebildet werden.The second screen may consist of a clear material, in particular of a clear, preferably dimensionally stable film. As a rule, the distance between the first screen and the second screen already ensures that particles retained by the second screen are not or at least not sharp depict the first screen. For better masking it can be provided that the second screen is formed at least partially diffusely scattering. Also in this embodiment, the second screen can be formed essentially by a preferably dimensionally stable film.

Bei der erfindungsgemäßen Leuchte kann als Material für den zweiten Schirm jedoch anstelle einer Folie auch ein anderes geeignetes Material vorgesehen sein.In the luminaire according to the invention, however, instead of a foil, another suitable material may be provided as the material for the second shade.

Erfindungsgemäß weist der zweite Schirm zumindest in dem für die Rückhaltewirkung relevanten Bereich keine Löcher auf, durch welche Insekten auf den ersten Schirm fallen können.According to the invention, the second screen, at least in the area relevant for the retention effect, has no holes through which insects can fall onto the first screen.

Erfindungsgemäß kann weiterhin vorgesehen sein, daß der zweite Schirm zumindest in dem Bereich zwischen der oder den Lampen und dem ersten Schirm gekrümmt ist.According to the invention, it can further be provided that the second screen is curved at least in the region between the lamp (s) and the first screen.

Zur besseren Reinigung kann vorgesehen sein, daß der zweite Schirm eine glatte Oberfläche aufweist.For better cleaning can be provided that the second screen has a smooth surface.

Weiterhin kann erfindungsgemäß vorgesehen sein, daß der zweite Schirm sich im wesentlichen über die gleiche Breite wie der erste Schirm erstreckt.Furthermore, it can be provided according to the invention that the second screen extends substantially over the same width as the first screen.

Dabei kann insbesondere vorgesehen sein, daß der erste und der zweite Schirm zwischen sich einen Raumbereich einschließen, der in einem Querschnitt senkrecht zu der Längsachse der Lampe bzw. den Lampen abgeschlossen ist. Damit wird insbesondere ein Eindringen von Insekten von der Seite vermieden.It can be provided in particular that the first and the second screen between them include a space region which is closed in a cross section perpendicular to the longitudinal axis of the lamp or the lamps. This prevents in particular insects from entering the site.

In einer speziellen Ausführungsform kann vorgesehen sein, daß der erste Schirm ein mit einer diffus streuenden Folie auf der Innenseite ausgekleidetes Lochblech aufweist.In a specific embodiment it can be provided that the first screen has a perforated plate lined with a diffusely scattering film on the inside.

Dabei kann das Lochblech eine Rinne bilden, von welcher die Lampe bzw. die Lampen zumindest teilweise umschlossen sind.In this case, the perforated plate can form a groove, from which the lamp or lamps are at least partially enclosed.

Bei der erfindungsgemäßen Lösung wird mit überraschend einfachen Mitteln das Problem der Verschlechterung des optischen Erscheinungsbilds der Leuchte durch tote Insekten und dgl. dadurch beseitigt, daß diese durch einen zweiten Schirm auf einem Abstand von dem ersten Schirm gehalten werden, so daß sie auf letzterem nicht mehr sichtbar sind. Damit kann, insbesondere, wenn der zweite Schirm aus einer transparenten klaren Folie besteht, eine größere Lichttransmission als bei der herkömmlichen Gitterlösung erreicht werden, da es - anders als bei Stahlgittern - nicht erforderlich ist, Löcher in das Material einzubringen, um eine Lichttransmission möglich zu machen. Ein weiterer Vorteil besteht darin, daß der zweite Schirm leicht zu reinigen ist.In the solution according to the invention the problem of deterioration of the optical appearance of the lamp by dead insects and the like. Is eliminated by surprisingly simple means that they are held by a second screen at a distance from the first screen, so that they no longer on the latter are visible. Thus, especially when the second screen is made of a transparent clear film, a greater light transmission can be achieved than with the conventional grid solution, since - unlike steel meshes - it is not necessary to introduce holes in the material to allow light transmission do. Another advantage is that the second screen is easy to clean.

Das in Fig. 1 und 2 dargestellte Ausführungsbeispiel der erfindungsgemäßen Leuchte weist ein rinnenförmig gebogenes Lochblech 1 auf, das an den beiden Stirnseiten durch eine Stirnwand 3 abgeschlossen ist, die mit seitlichen Blechen 4 das Lochblech 1 teilweise umgreift. In der Nähe der Stirnwände 3 sind Lampenfassungen 5 gehalten, zwischen denen sich die Lampe 7 im wesentlichen freitragend in der Rinne 1 erstreckt, von der sie weitgehend umschlossen ist. Ebenfalls zwischen den Stirnwänden 3 können Haltewinkel 9 für elektronisches Zubehör, wie Starter oder dgl., vorgesehen sein. Die Rinne 1 ist nach oben offen, so daß oberhalb der Lampe 7 eine sich im wesentlichen über die gesamte Länge der Lampe 7 erstreckende Lichtaustrittsöffnung gebildet wird, über die Licht nach oben abgegeben wird. Oberhalb dieser Lichtaustrittsöffnung ist ein Leuchtengehäuse 10 vorgesehen, von dem das Lochblech 1, wie aus Fig. 1 ersichtlich, über Halteelemente 11 abgehängt ist. In dem Gehäuse 10 ist ein Sekundärreflektor (nicht dargestellt) vorgesehen, der das Licht diffus reflektiert und im Raum verteilt. Durch das Lochblech 1 wird ein Teil des von der Lampe 7 abgestrahlten Lichts direkt nach unten abgegeben. Um einen direkten Blick auf die Lampe 7 zu verhindern, ist das Lochblech 1 mit einer opalisierten Spezialfolie 13 ausgekleidet, welche in etwa 50 % des Lichts reflektiert und das restliche Licht direkt durchläßt. Diese Folie 13 liegt direkt an der Innenseite der Lochblechrinne 1 an. Um zu vermeiden, daß Insekten, Staub und sonstiger Schmutz direkt auf die Folie 13 fallen, ist eine klare, formstabile Rückhaltefolie 15 zwischen der Lampe 7 und dem Lochblech 1 vorgesehen. Diese Rückhaltefolie 15 ist an den Rändern 17 des Lochblechs befestigt, vorzugsweise festgeklemmt, und in dem Innenbereich der Lochblechrinne sowohl von der Lampe 7 als auch von der Folie 13 beabstandet. In Längsrichtung erstreckt sich die Folie 15 zumindest über die Länge der Lampe, allgemeiner über denjenigen Bereich, der dem lichtdurchlässigen Bereich des Lochblechs 1 entspricht. Zwischen der Folie 15 und der Folie 13 wird damit ein Raumbereich 19 gebildet, der in einem Schnitt quer zur Längsrichtung abgeschlossen ist. Vorzugsweise ist dieser Raumbereich 19 allseitig geschlossen, so daß auch von der Seite keine Insekten eindringen können. Dieser Raumbereich kann jedoch ggf. an den beiden Stirnseiten offen sein oder es können in der Rückhaltefolie 15 kleine Löcher vorgesehen sein, durch die Insekten nicht fallen können, z.B. mit einem Durchmesser von weniger als 1 mm, etwa in einem Bereich von 0,01 bis 1 mm.The embodiment of the luminaire according to the invention shown in Fig. 1 and 2 has a groove-shaped curved perforated plate 1, which is closed at the two end faces by an end wall 3, which partially surrounds the perforated plate 1 with side plates 4. In the vicinity of the end walls 3 lamp sockets 5 are held, between which the lamp 7 extends substantially cantilevered in the channel 1, of which it is largely enclosed. Also, between the end walls 3 bracket 9 for electronic accessories, such as starters or the like. Be provided. The channel 1 is open at the top, so that above the lamp 7, a substantially over the entire length of the lamp 7 extending light exit opening is formed, is discharged via the light upwards. Above this light exit opening a luminaire housing 10 is provided, from which the perforated plate 1, as can be seen from FIG. 1, is suspended via holding elements 11. In the housing 10, a secondary reflector (not shown) is provided which reflects the light diffused and distributed in space. Through the perforated plate 1, part of the light emitted by the lamp 7 is emitted directly downwards. In order to prevent a direct view of the lamp 7, the perforated plate 1 is lined with an opalized special film 13, which reflects in about 50% of the light and transmits the remaining light directly. This film 13 is located directly on the inside of the perforated plate groove 1. In order to avoid that insects, dust and other dirt fall directly on the film 13, a clear, dimensionally stable retaining film 15 between the lamp 7 and the perforated plate 1 is provided. This retaining film 15 is fixed to the edges 17 of the perforated plate, preferably clamped, and spaced in the inner region of the perforated plate channel of both the lamp 7 and the film 13. In the longitudinal direction, the film 15 extends at least over the length of the lamp, more generally over that region which corresponds to the light-permeable region of the perforated plate 1. Between the film 15 and the film 13 so that a space portion 19 is formed, which is completed in a section transverse to the longitudinal direction. Preferably, this space area 19 is closed on all sides, so that no insects can penetrate from the side. However, this space area may possibly be open at the two end faces or it may be provided in the retaining film 15 small holes through which insects can not fall, for example, with a diameter of less than 1 mm, for example in a range of 0.01 to 1 mm.

Die Rückhaltefolie 15 bewirkt, daß Insekten, die in den Bereich der Lampen 7 gelangen und getötet werden, nicht direkt auf die Folie 13 bzw. auf die Löcher des Lochblechs 1 fallen, wo sie unmittelbar gesehen werden können, sondern in einem gewissen Abstand zurückgehalten werden, so daß sie sich optisch nicht bemerkbar machen. Als Folie 15 kann eine kostengünstige transparente Folie verwendet werden, die sich leicht abwischen läßt. Als Rückhaltefolie 15 kann auch eine diffus streuende Folie verwendet werden.The retaining film 15 causes insects that reach the area of the lamps 7 and killed, do not fall directly on the film 13 and on the holes of the perforated plate 1, where they can be seen directly, but are retained at a certain distance so that they do not make themselves visually noticeable. As a film 15, a low-cost transparent film can be used, which can be easily wipe off. As a retaining film 15, a diffusely scattering film can be used.
