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 lamp, in particular a suspended ceiling lamp or a recessed ceiling light, according to the preamble of claim 1. In a known Ceiling lamp, the lamp is housed in a channel made of a perforated plate, Above which a secondary reflector is arranged, which emits the light emitted upwards reflected down in the room. To get a uniform impression of brightness, the perforated plate is backed with a white film. The non-uniform deposit of dirt in the gutter (e.g. insects) leads to clearly visible dark spots in the gutter, which 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 Meine 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 previously been proposed to use a fine mesh, e.g. made of steel, to be arranged between the lamp and the perforated plate. The previous one Outlined pollution problem is not completely solved, however, because insects partly falling through or crawling through my holes. A such a grid also has the disadvantage that it is not easy to clean and if it is sufficiently fine-meshed, the light transmission is clearly impeded.

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 lamp according to the preamble of claim 1 to provide at the dead insects and the like from the first screen where they make themselves visually noticeable, reliably restrained with little loss of light become.

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 aus einem lichtdurchlässigen Material von dem ersten Schirm beabstandet angeordnet ist. Die Leuchte kann dabei insbesondere eine Deckeneinbauleuchte, eine Anbauleuchte, eine Pendelleuchte oder eine Stehleuchte sein.According to the invention, this problem is solved by a lamp, in particular by a ceiling lamp, with one or more lamps, accessible from the outside in a way are that dirt or insects can enter the area of the lamps, and an at least partially translucent first screen, through which in the state of use the light is emitted downwards, which is characterized by is that in the light path between the first screen and the lamp or the Lamps a second screen made of a translucent material from the first Screen is spaced. The lamp can in particular be a recessed ceiling lamp, a surface-mounted lamp, a pendant lamp 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.The second screen is mounted so that it is at least for the Area around the lamps prevents dead insects, Dirt particles or the like fall from this area onto 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 abgeschirmt sind.The invention can be used in particular in the case of lamps which have an outward-pointing lamp Have opening to the lamp area, especially those that are in use have an upward opening or where the lamp or lamps are not shielded from above.

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 streuend, insbesondere diffus streuend, ausgebildet ist. Auch bei dieser Ausführungsform kann der zweite Schirm im wesentlichen durch eine vorzugsweise formstabile Folie gebildet werden.The second screen can be made of a clear material, in particular a clear, preferably dimensionally stable film exist. Usually the distance between the first ensures Umbrella and the second umbrella are already different from the second umbrella Do not, or at least not sharply, show any retained particles on the first screen. For better masking it can be provided that the second screen at least is partially scattering, in particular diffusely scattering. Also in this embodiment can the second screen essentially by a preferably dimensionally stable Foil are formed.

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, can be used as the material for the second screen another suitable material may also be provided instead of a film.

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 has at least one for the restraining effect relevant area no holes through which insects fall on the first screen can.

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 at least in the area between the lamp or lamps and the first screen is curved.

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

Weiterbin kann erfindungsgemäß vorgesehen sein, daß der zweite Schirm sich im wesentlichen über die gleiche Breite wie der erste Schirm erstreckt.Next bin can be provided according to the invention that the second screen substantially extends 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 in particular be provided that the first and the second screen between enclose a spatial area that is perpendicular to the longitudinal axis in a cross section the lamp or lamps is complete. This is particularly an intrusion avoided from the side by insects.

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 special embodiment it can be provided that the first screen has a a diffusely scattering film on the inside lined perforated plate.

Dabei kann das Lochblech eine Rinne bilden, von welcher die Lampe bzw. die Lampen zumindest teilweise umschlossen sind.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 is solved with surprisingly simple means the deterioration in the visual appearance of the lamp due to dead insects and the like. by removing them by a second screen at a distance are held by the first screen so that they are no longer visible on the latter are. This can, especially if the second screen is made of a transparent clear Film, there is greater light transmission than with the conventional grating solution can be achieved because - unlike steel grids - holes are not required into the material to make light transmission possible. A 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 shown in FIGS. 1 and 2 of the lamp according to the invention has a trough-shaped perforated plate 1, which on both ends an end wall 3 is completed, the perforated plate 1 partially with side plates 4 embraces. In the vicinity of the end walls 3, lamp holders 5 are held between which the lamp 7 extends substantially self-supporting in the groove 1, from which is largely enclosed. Brackets can also be between the end walls 3 9 for electronic accessories, such as starters or the like. The gutter 1 is open at the top, so that above the lamp 7 is essentially over the Entire length of the lamp 7 extending light exit opening is formed, via the Light is emitted upwards. There is a luminaire housing above this light exit opening 10 provided, of which the perforated plate 1, as shown in Fig. 1, via holding elements 11 is suspended. In the housing 10 there is a secondary reflector (not shown) provided that diffusely reflects the light and distributes it in the room. 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 lined with an opalized special film 13, which reflects about 50% of the light and lets the rest of the light through. This film 13 is located directly on the inside the perforated sheet tray 1. To avoid insects, dust and other Dirt falling directly onto the film 13 is a clear, dimensionally stable retaining film 15 between the lamp 7 and the perforated plate 1 are provided. This retaining film 15 is on the Edges 17 of the perforated plate attached, preferably clamped, and in the interior the perforated plate channel spaced both from the lamp 7 and from the film 13. In the longitudinal direction, the film 15 extends at least over the length of the lamp, more generally about that area which is the translucent area of the perforated plate 1 corresponds. A space is thus between the film 15 and the film 13 19 formed, which is completed in a section transverse to the longitudinal direction. Preferably this room area 19 is closed on all sides, so that no insects from the side either can penetrate. However, this area of space may be on the two faces be open or 15 small holes can be provided in the retaining film, through which insects cannot fall, e.g. with a diameter of less than 1 mm, approximately 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 streuende, vorzugsweise eine diffus streuende Folie verwendet werden.The retaining film 15 causes insects to get into the area of the lamps 7 and killed, not directly on the film 13 or on the holes in the perforated plate 1 fall where they can be seen immediately, but at some distance be held back so that they are not visually noticeable. As slide 15 an inexpensive transparent film can be used that wipes easily leaves. A scattering, preferably a diffuse, can also be used as the retaining film 15 scattering foil can be used.
