Abstract

The light has an elongated housing symmetrical wrt. a vertical plane, transparent for downward light emanation and open at the top. Two light tubes (28) are mounted in the housing at equal distances on both sides of the centre plane. At least one reflector (30) is mounted in the housing near each light tube to deflect the light at least partly upwards. Each reflector is a holed plate with a vertical section (32) on one side of the light tube, an approximately horizontal section (34) above the tube and a third section (36) inclined upwards from the centre plane.

Description

Die Erfindung betrifft eine breitstrahlende Indirektleuchte nach dem Oberbegriff des Anspruchs 1.The invention relates to a wide-beam indirect light according to the preamble of claim 1.

Aus DE 195 37 685 C1 ist eine derartige Indirektleuchte bekannt, durch deren Ausgestaltung das Problem gelöst ist, daß trotz eines kleinen Abstands zwischen Raumdecke und Unterkante der Leuchte eine zu hohe Leuchtdichte an der Decke unmittelbar oberhalb der Leuchte vermieden wird, andererseits der größere Teil des abgestrahlten Lichtes seitlich und schräg nach oben abgestrahlt wird, um eine gute und gleichmäßige Ausleuchtung des Raumes zu erzielen.Such an indirect light is known from DE 195 37 685 C1 known, the design of which solves the problem, that despite a small distance between the ceiling and The lower edge of the lamp has too high a luminance on the Ceiling immediately above the lamp is avoided, on the other hand the greater part of the emitted light from the side and is emitted diagonally upwards to a good and to achieve uniform illumination of the room.

Während diese bekannte Indirektleuchte für Leuchtröhren mit einem Durchmesser von 26 mm und entsprechender Leuchtdichte das geschilderte Problem ausgezeichnet löst, wird das Problem durch die Verwendung von Leuchtröhren mit 16 mm Durchmesser so verschärft, daß die bekannte Leuchte nicht mehr in allen Fällen ausreicht. While using this well-known indirect light for fluorescent tubes a diameter of 26 mm and corresponding luminance solves the described problem excellently, the problem becomes through the use of fluorescent tubes with a diameter of 16 mm so sharpened that the known lamp no longer in all Cases is sufficient.

Durch die Erfindung soll daher eine Leuchte der eingangs genannten Art so verbessert werden, daß auch bei Leuchtröhren mit kleinerem Durchmesser eine gute und gleichmäßige Ausleuchtung des Raumes bei Vermeidung einer zu starken Leuchtdichte an der Decke unmittelbar oberhalb der Leuchte erzielt werden kann.The invention is therefore intended to be a lamp of the beginning mentioned type can be improved so that even with fluorescent tubes with a smaller diameter a good and even illumination of the room while avoiding excessive luminance achieved on the ceiling directly above the lamp can be.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of Claim 1 solved.

Durch die Verwendung von Reflektoren aus Lochblech seitlich und oberhalb der Leuchtröhren wird einerseits eine ausreichende Aufhellung der Decke oberhalb der Leuchte erreicht, andererseits eine zu starke Leuchtdichte in diesem nahe der Leuchte gelegenen Bereich der Decke vermieden. Ahdererseits wird der größere Teil der Lichtabstrahlung in einem großen Winkelbereich seitlich nach oben abgelenkt, ohne daß eine Blendung in einer seitlich etwas nach unten weisenden Richtung hervorgerufen wird.By using reflectors made of perforated sheet metal on the side and above the fluorescent tubes, on the one hand, there is sufficient The ceiling above the luminaire has brightened, on the other hand a too high luminance in this near the Avoid luminaire located area of the ceiling. On the other hand the greater part of the light radiation is in a large Angular range deflected laterally upwards without a Glare in a direction pointing downwards to the side is caused.

In den Unteransprüchen sind vorteilhafte Ausgestaltungen der Erfindung unter Schutz gestellt. Die Anordnung von Lochblechteilen im Gehäuse zusammen mit weiteren Reflektoren im mittleren, seitlichen und unteren Bereich des Innenraums des Leuchtengehäuses kann wahlweise für eine noch gleichmäßigere Lichtverteilung und Vermeidung von Schattenbildungen und insbesondere für eine gleichmäßige Aufhellung des Gehäuses nach unten sorgen.Advantageous refinements of the Invention protected. The arrangement of perforated sheet metal parts in the housing together with other reflectors in the middle, side and bottom of the interior of the Luminaire housing can optionally be used for an even smoother Light distribution and avoidance of shadows and especially for uniform lightening of the housing worry down.

Da der Abstand A von der Raumdecke 10 zur Unterkante 12 des Leuchtengehäuses 14 gemäß Fig.1 möglichst klein sein soll, ist das verhältnismäßig flache Leuchtengehäuse 14 mittels eines kurzen Leuchtenschaftes 16 und einer etwa kegelförmigen Deckenrosette 18 in kurzem Abstand von der Decke 10 befestigt. Das Leuchtengehäuse 14 ist nach unten leicht konvex gekrümmt und besteht aus lichtdurchlässigem Material, das jedoch z.B. in Form von Lochblech, Gittergewebe, Gittergeflecht, Milchglas oder mittels anderen perforierten Materials wahlweise mehr oder weniger Licht nach unten durchlassen kann. An den Seitenkanten des Leuchtengehäuses 14 endet dasselbe jeweils in oben umgebogenen Abschnitten 22. Nach oben ist das Leuchtengehäuse 14 offen.Since the distance A from the ceiling 10 to the lower edge 12 of the 1 should be as small as possible, is the relatively flat lamp housing 14 by means of a short lamp shaft 16 and an approximately conical one Ceiling rosette 18 attached at a short distance from the ceiling 10. The lamp housing 14 is slightly convex downwards curved and is made of translucent material that however e.g. in the form of perforated sheet, mesh, mesh, Frosted glass or other perforated material optionally let more or less light down can. Ends at the side edges of the lamp housing 14 the same in each case in sections 22 bent over the lamp housing 14 is open at the top.

Das Leuchtengehäuse 14 ist symmetrisch zu einer in Richtung der Längserstreckung des Leuchtengehäuses 14 verlaufenden vertikalen Mittelebene 26 ausgebildet. In gleichen Abständen von der Mittelebene 26 sowie in gleicher Höhe oberhalb des Gehäuses 14, d.h. etwa in der Höhe der umgebogenen Abschnitte 22 des Leuchtengehäuses 14, ist je eine parallel zur Mittelebene 26 verlaufende Leuchtröhre 28 angeordnet.The lamp housing 14 is symmetrical to one in the direction the longitudinal extent of the lamp housing 14 extending vertical center plane 26 formed. At equal intervals from the central plane 26 and at the same height above the Housing 14, i.e. approximately at the level of the bent sections 22 of the lamp housing 14, one is parallel to the central plane 26 extending tube 28 arranged.

Nahe jeder Leuchtröhre 28 ist ein aus Lochblech bestehender Hochglanz-Reflektor angeordnet, der allgemein mit 30 bezeichnet ist. Ein erster etwa vertikaler Abschnitt 32 liegt an der der Mittelebene 26 zugewandten Seite der zugehörigen Leuchtröhre 28 an und ragt etwas über dieselbe nach oben. In geringem Abstand von der Oberseite der Leuchtröhre 28 schließt sich an den ersten Abschnitt 32 ein zweiter etwa horizontaler Abschnitt 34 des Reflektors 30 an, dessen Länge annähernd dem Durchmesser der Leuchtröhre 28 entspricht. Der zweite Abschnitt 34 geht sodann in einen dritten, von der Mittelebene 26 weg nach oben geneigten längeren Abschnitt 36 über, der nach oben leicht konvex und nach unten leicht konkav gewölbt ist. Bei der dargestellten Ausführungsform besitzt er eine mittlere Steigung von etwa 45°. Im vertikalen Schnitt der Fig.1 beträgt die Länge des dritten Abschnitts 36 das Mehrfache des ersten Abschnitts 32 bzw. des zweiten Abschnitts 34.Near each tube 28 is a perforated plate High-gloss reflector arranged, generally designated 30 is. A first approximately vertical section 32 lies on the the central plane 26 side of the associated fluorescent tube 28 and protrudes slightly above it. In a little Distance from the top of the tube 28 closes to the first section 32 a second approximately horizontal Section 34 of the reflector 30, the length of which approximately Diameter of the fluorescent tube 28 corresponds. The second section 34 then goes into a third, from the middle level 26 away upward sloping longer section 36 over the slightly convex upwards and slightly concave downwards is. In the illustrated embodiment, it has one average slope of about 45 °. In vertical section the 1 the length of the third section 36 is a multiple of the first section 32 and the second section 34.

Im Bereich zwischen den beiden Reflektoren 30 und den beiden Leuchtröhren 28 ist ein symmetrisch zur Mittelebene 26 angeordneter Mittelreflektor 38 vorgesehen, der zu beiden Seiten der Mittelebene 26 je eine obere, nach oben zur Mittelebene 26 hin geneigte ebene Reflektorfläche 40 und je eine untere, nach unten zur Mittelebene hin geneigte, im wesentlichen ebene Reflektorfläche 42 aufweist. Der Mittelreflektor 38 weist ferner je einen nach unten von der Mittelebene 26 weg geneigten, jeweils unterhalb einer der Leuchtröhren 28 angeordneten Unterreflektor 44 auf, der mit ihm einstückig oder auf sonstige Weise starr verbunden ist. Jeweils zwischen der unteren ebenen Reflektorfläche 42 und dem oberen Rand 46 des Unterreflektors 44 ist ein parallel zur Mittelebene 26 über die Länge der gesamten Leuchte verlaufender Durchbruch 48 vorgesehen, der allenfalls durch nicht dargestellte, dünne Haltestege oder dergleichen unterbrochen sein kann. Der gesamte Mittelreflektor 38 einschließlich des Unterreflektors 44 besteht vorzugsweise aus geschlossenem Hochglanzmaterial. Der untere Rand 50 des ersten vertikalen Abschnitts 32 jedes Reflektors 30 liegt vorzugsweise an der Oberseite des zugehörigen Unterreflektors 44 an.In the area between the two reflectors 30 and the two Luminous tubes 28 is arranged symmetrically to the central plane 26 Center reflector 38 provided on both sides the middle plane 26 an upper, up to the middle plane 26 inclined flat reflector surface 40 and a lower, essentially sloping down towards the median plane has flat reflector surface 42. The center reflector 38 also points downward from the central plane 26 inclined, each arranged below one of the fluorescent tubes 28 Sub-reflector 44, which is integral with it or is otherwise rigidly connected. Between each lower flat reflector surface 42 and the upper edge 46 of the Sub-reflector 44 is parallel to the central plane 26 the length of the entire opening 48 provided, at most by thin, not shown Retaining bars or the like can be interrupted. Of the entire center reflector 38 including the sub-reflector 44 is preferably made of closed high-gloss material. The lower edge 50 of the first vertical section 32 each Reflector 30 is preferably on the top of the associated Sub-reflector 44 on.

Oberhalb der von der Mittelebene 26 abgelegenen seitlichen Abschnitte D des Leuchtengehäuses 14 ist jeweils im Abstand etwa parallel zu diesen je ein Seitenreflektor 52 angebracht. Er verläuft etwa von den umgebogenen Abschnitten 22 des Gehäuses 14 bis zu seinem inneren Rand 54 jeweils in geringem Abstand unterhalb der zugehörigen Leuchtröhre 28 und oberhalb des zugehörigen Unterreflektors 44 und ist bis auf die äußeren Randbereiche im wesentlichen eben. Er besteht vorzugsweise ebenfalls aus geschlossenem Hochglanzmaterial und ist zur Mittelebene hin nach unten leicht geneigt, so daß zwischen dem Seitenreflektor 52 und dem dritten Abschnitt 36 des zugehörigen Reflektors 30 ein sich nach oben öffnender, von Reflektoren unbehinderter Abstrahlwinkel B für das Licht der zugehörigen Leuchtröhre 28 gebildet wird. Der Abstrahlwinkelbereich B weist schräg seitlich nach oben, wodurch Blendungen in Blickrichtung des Pfeils G von schräg unten sicher vermieden werden, jedoch eine gute und gleichmäßige Ausleuchtung des Raumes seitlich und nach oben erreicht wird. Der dritte gewölbte Abschnitt 36 des Lochblechreflektors 30 ist bestimmend für die Größe des Abstrahlwinkels B. Die direkte Abstrahlung von der Leuchtröhre 28 nach unten in Richtung des Gehäuses 14 wird durch den Seitenreflektor 52 und den Unterreflektor 44 verhindert. Gleichzeitig unterstützt der Seitenreflektor 52 jeweils die breitstrahlende Charakteristik der Leuchte, die im wesentlichen durch den Winkel B bestimmt wird. Above the lateral ones remote from the central plane 26 Section D of the lamp housing 14 is spaced apart a side reflector 52 is attached approximately parallel to each. It runs approximately from the bent portions 22 of the Housing 14 up to its inner edge 54 each in a small amount Distance below the associated fluorescent tube 28 and above of the associated sub-reflector 44 and is except for the outer Edge areas essentially flat. It preferably exists also made of closed high-gloss material and is for Median plane slightly inclined downwards, so that between the side reflector 52 and the third section 36 of the associated reflector 30 an opening upwards from Reflectors unobstructed beam angle B for the light of the associated fluorescent tube 28 is formed. The beam angle range B points diagonally upwards, causing glare safely avoided in the direction of arrow G from obliquely below a good and even illumination of the room is reached laterally and upwards. The third curved section 36 of the perforated plate reflector 30 is decisive for the size of the beam angle B. The direct beam from the tube 28 down towards the Housing 14 is through the side reflector 52 and the sub-reflector 44 prevented. At the same time, the side reflector supports 52 each have the wide-beam characteristic of Luminaire essentially determined by the angle B. becomes.

Über dem Mittelreflektor 38 und den Leuchtröhren 28 ist eine lichtdurchlässige horizontale Abdeckplatte 56 angebracht, die einen gewissen Schutz gegen Verschmutzung des Mittelreflektors 38 und der Leuchtröhren 28 bietet.One is above the central reflector 38 and the fluorescent tubes 28 translucent horizontal cover plate 56 attached some protection against contamination of the central reflector 38 and the fluorescent tubes 28 offers.

Die geschilderte Form der drei Abschnitte der beiden Lochblechreflektoren 30 dient zu einer gewissen, jedoch nicht vollständigen Abschattung der Leuchtröhren 28 in Richtung Decke 10 oberhalb der Reflektoren 30. Es ergibt sich dabei durch das Lochblech dieser Reflektoren 30 ein durch den Winkel C bestimmter Abstrahlbereich unmittelbar nach oben gegen die Decke 10.The described shape of the three sections of the two perforated sheet reflectors 30 serves for a certain, but not complete Shading of the fluorescent tubes 28 towards the ceiling 10 above the reflectors 30. It results from the perforated plate of these reflectors 30 determined by the angle C. Beam area directly up against the ceiling 10.

Um auch das Leuchtengehäuse 14 selbst möglichst gleichmäßig aufzuhellen, wird durch den Spalt zwischen dem inneren Rand 54 des Seitenreflektors 52 und der Oberseite des Unterreflektors 44 jeweils direkt Licht von der Leuchtröhre 28 in einen Winkelbereich D' eingestrahlt, um die seitlichen Abschnitte D des Gehäuses 14 aufzuhellen. Durch die ersten Abschnitte 32 der Lochblechreflektoren 30 abgestrahltes Licht wird über die unteren Reflexionsflächen 42 des Mittelreflektors 38 jeweils durch den Durchbruch 48 desselben nach unten in einem Winkelbereich E' auf den mittleren Abschnitt E des Gehäuses 14 reflektiert, während direkt durch die Durchbrüche 48 von den Leuchtröhren 28 abgestrahltes Licht in Winkelbereichen E'' auf den mittleren Abschnitt E auftreffen. Teilweise ist dabei der Einstrahlwinkel so flach, daß kein direktes Licht etwa durch Löcher eines Lochblechmaterials des Gehäuses 14 nach außen dringen würde. Dadurch wird eine weitgehend gleichmäßige Aufhellung des Gehäuses 14 erreicht. Um dies zu optimieren, könnte vorteilhafterweise eine transparente Folie auf die Innenseite des Gehäuses 14 aufgelegt werden. To even the lamp housing 14 itself as evenly as possible is brightened by the gap between the inner edge 54 of the side reflector 52 and the top of the sub-reflector 44 each directly light from the tube 28 in an angular range D 'irradiated to the side portions D of the Brighten housing 14. Through the first sections 32 of the Perforated plate reflectors 30 emitted light is on the lower Reflection surfaces 42 of the center reflector 38 each through the opening 48 of the same downward in an angular range E ' reflected on the central portion E of the housing 14 while directly through the openings 48 from the fluorescent tubes 28 emitted light in angular ranges E '' on the middle Impact Section E. The angle of incidence is partial so flat that there is no direct light, for example, through holes in a perforated sheet material of the housing 14 would penetrate to the outside. Thereby is a largely uniform lightening of the case 14 reached. To optimize this, it could be advantageous a transparent film is placed on the inside of the housing 14 become.
