Description

Die Erfindung betrifft eine Leuchte mit mindestens einem elektrischen Leuchtmittel und mit einem letzterem zugeordneten, aus lichtdurchlässigem Werkstoff bestehenden Leuchtenschirm entsprechend dem Oberbegriff des Anspruchs 1. Eine solche Leuchte ist in der DE 198 01 568 C2 beschrieben.The invention relates to a luminaire with at least one electric lamp and associated with a latter, made of translucent material lampshade according to the preamble of claim 1. Such a lamp is in the DE 198 01 568 C2 described.

Die bekannte Leuchte weist einen etwa konusartigen Leuchtenschirm aus milchigem undurchsichtigen transluzenten Glas auf, dessen freier Rand so gestaltet ist, dass sich zwei Vorsprünge mit zwei Ausnehmungen abwechseln. Die beiden Vorsprünge des bekannten Leuchtenschirms sind an einander diametral gegenüberliegenden Umfangsstellen mit je einem Durchbruch versehen. Jeder Durchbruch, welcher lediglich eine hinsichtlich der Lichtwirkung der bekannten Leuchte nicht relevante Befestigungsaussparung bildet, dient der Aufnahme des jeweiligen axialen Endbereichs eines bezüglich seiner Längserstreckung etwa teilkreisförmig nach unten gebogenen Stabes aus transluzentem klardurchsichtigen Glas oder aus Acrylglas.The known luminaire has an approximately conical lampshade of milky opaque translucent glass, whose free edge is designed so that two projections alternate with two recesses. The two projections of the known lampshade are provided at diametrically opposite circumferential locations, each with an opening. Each breakthrough, which forms only one with respect to the light effect of the known light not relevant mounting recess, serves to receive the respective axial end portion of a longitudinal extent about its part-circular downward bent rod made of translucent clear glass or acrylic glass.

Der im Leuchteninnenraum angeordnete Stab befindet sich unmittelbar im Strahlungsfluß des elektrischen Leuchtmittels und ist zugleich von einer Betrachtungsstelle, die außen im Schattenraum des Leuchtenschirms angeordnet ist, sichtbar, wobei eine direkte Blendung ausgeschlossen ist. Bei der von der DE 198 01 568 C2 bekannten Leuchte reflektiert und/oder leitet der Stab das Licht und bildet dadurch mit seinem im Strahlungsfluß des Lichts befindlichen Bereich quasi eine stabförmige dekorative sekundäre Lichtquelle.The arranged in the lamp interior rod is located directly in the radiant flux of the electric bulb and is also visible from a viewing point, which is arranged outside in the shadow space of the lampshade, with a direct glare is excluded. At the of the DE 198 01 568 C2 the known light reflects and / or passes the rod, the light and thus forms with its in the radiation flow of the light located area quasi a rod-shaped decorative secondary light source.

Von der DE 44 42 584 C1 ist eine Leuchten-Abdeckung für Decken-, Boden- oder Wandleuchten bekannt, die einen aus Glas bestehenden hohlen Leuchtenkörper aufweist, dessen dem Befestigungsrand benachbarter oberer Bereich aus zwar lichtdurchlässigem, jedoch mattem Glas besteht, während der sich daran anschließende untere Bereich klardurchsichtig ist. Der klardurchsichtige Bereich des Leuchtenkörpers ist von einem klardurchsichtigen scheibenartigen Glaskörper überlagert, dessen Lichtaustrittsfläche von dem klardurchsichtigen Bereich des Leuchtenkörpers gänzlich untergriffen ist.Of the DE 44 42 584 C1 a luminaire cover for ceiling, floor or wall luminaires is known, which has a hollow glass body consisting of glass, the adjacent upper edge of the attachment area consists of translucent, but frosted glass, while the adjoining lower area is clear. The clear area of the lamp body is superimposed by a clear transparent disc-like glass body whose light exit surface is completely undercut by the clear-glass region of the lamp body.

Aus der GB 956,199 , ist ein Lampenschirm bekannt, welcher aus semitransparentem Kunststoffmaterial besteht, wobei in Öffnungen des Lampenschirms transparente farbige Kunststoffeinsätze angeordnet sind. Die Einsätze weisen eine umlaufende Nut auf, in welcher die Laibung der Öffnung eingreift. Die Außenkontur der Einsätze ist etwas größer als die dafür vorgesehene Öffnung im Lampenschirm. Aufgrund der Flexibilität des Kunststoffmaterials des Lampenschirms können die Einsätze jedoch soweit in die Öffnung bewegt werden, bis die Laibung der Öffnung in die Nut des Einsatzes einrastet.From the GB 956,199 , a lampshade is known, which consists of semitransparent plastic material, wherein in openings of the lampshade transparent colored plastic inserts are arranged. The inserts have a circumferential groove in which engages the soffit of the opening. The outer contour of the inserts is slightly larger than the opening provided in the lampshade. However, due to the flexibility of the plastic material of the lampshade, the inserts can be moved into the opening until the sash of the opening engages the groove of the insert.

Ausgehend von der GB 956,199 liegt der Erfindung die Aufgabe zugrunde, den Leuchtenschirm und den von diesem gehaltenen klardurchsichtigen Körper zur Erzielung zusätzlicher eigenartiger Lichtreflekte und einer einfacheren Herstellung vorteilhaft abzuwandeln.Starting from the GB 956,199 The object of the invention is to advantageously modify the lampshade and the clear-transparent body held by the latter in order to achieve additional peculiar light reflections and a simpler production.

Die Aufgabe wird gemäß einem ersten Aspekt der Erfindung gelöst mit den Merkmalen des Anspruchs 1, insbesondere mit den kennzeichnenden Merkmalen.The object is achieved according to a first aspect of the invention with the features of claim 1, in particular with the characterizing features.

Gemäß einem zweiten Aspekt der Erfindung wird die Aufgabe gelöst mit den Merkmalen des Anspruchs 11, insbesondere mit den kennzeichnenden Merkmalen.According to a second aspect of the invention, the object is achieved with the features of claim 11, in particular with the characterizing features.

Im Unterschied zu der von der DE 198 01 568 C2 bekannten Leuchte, bei welcher die Durchbrüche lichttechnisch unwirksame Befestigungsaussparungen darstellen , besteht entsprechend der Erfindung jeder Durchbruch aus einer die Leuchtenschirmwand durchsetzenden hinreichend großen fensterartigen Lichtdurchtrittsöffnung.In contrast to that of the DE 198 01 568 C2 known luminaire, in which the apertures represent lighting technically ineffective mounting recesses, consists according to the Invention every breakthrough from a the lampshade wall passing through sufficiently large window-like light passage opening.

Eine jede Lichtdurchtrittsöffnung wird erfindungsgemäß lichttechnisch gestaltet, indem in oder an der rahmenartigen Laibung der fensterartigen Lichtdurchtrittsöffnung ein letztere zumindest im wesentlichen ausfüllender klardurchsichtiger Körper angeordnet ist.Each light passage opening is designed according to the invention lighting technology, by a last at least substantially filling clear transparent body is arranged in or on the frame-like reveal of the window-like light passage opening.

Im Unterschied zur Leuchte der DE 198 01 568 C2 , gemäß welcher der klardurchsichtige Körper aus einem langgestreckten Stab besteht, weist der klardurchsichtige Körper entsprechend der Erfindung eine gedrungene Form auf, welche von etwa prismenähnlich angeordneten Teilflächen umhüllt ist.In contrast to the light of the DE 198 01 568 C2 according to which the clear-transparent body consists of an elongated rod, the clear-transparent body according to the invention has a compact shape, which is enveloped by approximately prism-like arranged partial surfaces.

Diese prismenähnlich angeordneten Teilflächen beeinflussen das Licht, indem sie es reflektieren, brechen und ggf. in dessen Spektralfarben zerlegen. Auf diese Weise lockern die mit den klardurchsichtigen Körpern im wesentlichen ausgefüllten fensterartigen Lichtdurchtrittsöffnungen die ansonsten einheitliche Oberfläche eines Leuchtenschirms in eigenartiger Weise aufThese prism-like arranged partial surfaces influence the light by reflecting it, breaking it and possibly decomposing it into its spectral colors. In this way, the window-like light passage openings substantially filled with the clear-transparent bodies loosen the otherwise uniform surface of a lampshade in a peculiar manner

Der lichtdurchlässige Werkstoff des erfindungsgemäßen Leuchtenschirms ist vorzugsweise Glas, kann aber auch aus einem chemischen Werkstoff, beispielsweise aus Acrylglas, gefertigt sein. Dasselbe gilt für den klardurchsichtigen Körper, welcher vorzugsweise aus Glas, andererseits aber auch aus einem anderen Werkstoff, beispielsweise aus Acrylglas; bestehen kann.The translucent material of the lampshade according to the invention is preferably glass, but can also be made of a chemical material, for example made of acrylic glass. The same applies to the clear-transparent body, which is preferably made of glass, but on the other hand also of another material, such as acrylic glass; can exist.

Eine vorteilhafte ansprechende Lichtwirkung ergibt sich dann, wenn die Leuchtenschirmwand mindestens teilweise aus einem matten lichtdurchlässigen Werkstoff, wie z.B. aus Opalglas, gebildet ist oder eine mattierte Innenfläche und/oder Außenfläche aufweist. Auf diese Weise ergibt sich ein interessanter Lichtkontrast zwischen der überwiegend aus mattem Werkstoff bestehenden und daher diffus abstrahlenden Leuchtenschirmwand und den mit ihren klardurchsichtigen Körpern das Licht lenkenden Lichtdurchtrittsöffnungen.An advantageous attractive lighting effect is obtained when the lampshade wall is at least partially made of a matt translucent material, such as opal glass, or a has matted inner surface and / or outer surface. In this way, there is an interesting light contrast between the predominantly made of matt material and therefore diffuse radiating lampshade wall and the light transparent openings with their clear-body translucent.

Eine besonders bevorzugte Ausführungsform besteht darin, dass der klardurchsichtige Körper mit einem Teilbereich an der Außenfläche der Leuchtenschirmwand benachbart der rahmenartigen Laibung der fensterartigen Lichtdurchtrittsöffnung angeordnet ist und die Außenfläche an einem Randbereich der fensterartigen Lichtdurchtrittsöffnung übergreift, wobei sich zwischen dem Teilbereich des klardurchsichtigen Körpers und dem Randbereich der fensterartigen Lichtdurchtrittsöffnung eine Klebefuge befindet.A particularly preferred embodiment consists in that the clear-transparent body is arranged with a partial area on the outer surface of the lampshade wall adjacent to the frame-like reveal of the window-like light passage opening and the outer surface engages over an edge region of the window-like light passage opening, wherein between the portion of the clear-transparent body and the edge region the window-like light passage opening is an adhesive joint.

Entsprechend dieser Ausführungsform kann der klardurchsichtige Körper von außen in die Lichtdurchtrittsöffnung, deren nach außen weisenden Randbereich zugleich abdeckend, eingesetzt werden. Zwischen dem Randbereich der Lichtdurchtrittsöffnung und dem überstehenden Randbereich des klardurchsichtigen Körpers kann sodann gewissermaßen versteckt eine Fuge mit klardurchsichtigem Kleber angebracht werden.According to this embodiment, the clear-transparent body can be inserted from the outside into the light passage opening, the outwardly facing edge region at the same time covering. Between the edge region of the light passage opening and the protruding edge region of the clear-transparent body, a gap with clear-transparent adhesive can then, as it were, be hidden.

Weitere Erfindurigsmerkmale sind zusätzlichen Unteransprüchen zu entnehmen.Further features of the invention can be found in additional subclaims.

Jeder klardurchsichtige Körper 23 ist mit etwa prismenähnlich angeordneten unterschiedlichen Teilflächen versehen, welche unabhängig von ihrer jeweiligen Flächengröße und Flächengestalt jeweils mit der Bezugsziffer 30 versehen sind.Each clear-transparent body 23 is provided with approximately different prism-like arranged partial surfaces, which are each provided with the reference numeral 30 regardless of their respective area size and surface shape.

Insbesondere anhand der Fig. 2 und 3 ist vorstellbar, dass die Innenseite des klardurchsichtigen Körpers 23 eine dem Leuchtmittel 13 zugewandte und dem Betrachter abgekehrte beleuchtete Fläche 31 und die Außenseite des klardurchsichtigen Körpers 23 eine dem Leuchtmittel 13 abgewandte Lichtaustrittsfläche 32 bildet, die dem Betrachter unmittelbar zugekehrt ist. Die Lichtaustrittsfläche 32 stellt eine sekundäre Lichtquelle dar.With particular reference to FIGS. 2 and 3, it is conceivable that the inside of the clear-transparent body 23 forms a light-emitting surface 31 facing the light source 13 and facing away from the viewer, and the outside of the clear-transparent body 23 forms a light emergence surface 32 facing away from the light source 13 is facing. The light exit surface 32 represents a secondary light source.
