Description

Die Erfindung betrifft eine Leuchte und ein Basisteil nach dem Oberbegriff des Anspruchs 1, 7 oder 11.The invention relates to a lamp and a base part according to the preamble of claim 1, 7 or 11.

Eine Leuchte bzw. ein Basisteil dieser Art ist bekannt. Die bekannte Leuchte bzw. das Basisteil ist von länglicher und rechteckiger Bauform, die durch ein im wesentlichen flaches Basisteil mit Mitteln zum Befestigen an einem Träger, z. B. an einer Wand oder Decke, und einer wannenförmigen Abdeckung gebildet ist, die mittels lösbaren Befestigungselementen mit dem Basisteil verbunden ist. Diese vorbekannte Leuchte erfüllt einen weniger anspruchsvollen Beleuchtungszweck, z. B. in Treppenhäusern, Kellern, Feuchträumen, Garagen, Hallen u. dgl. Da die Abdeckung aus opalem Material besteht, ist die bekannte Leuchte blendfrei, was jedoch die Leuchtleistungsausnutzung etwas beeinträchtigt.A lamp or a base part of this type is known. The known lamp or the base part is of elongated and rectangular design, which by a substantially flat base part with means for fastening to a carrier, for. B. on a wall or ceiling, and a trough-shaped cover is formed, which is connected to the base part by means of releasable fastening elements. This previously known lamp fulfills a less demanding lighting purpose, e.g. B. in stairwells, basements, wet rooms, garages, halls and. Like. Since the cover is made of opal material, the known lamp is glare-free, but this somewhat affects the utilization of light output.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Leuchte der eingangs angegebenen Art die Leuchtleistung zu verbessern.The invention has for its object to improve the light output in a lamp of the type specified.

Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche 1, 7 oder 11 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.This object is solved by the features of independent claims 1, 7 or 11. Advantageous developments of the invention are described in the subclaims.

Bei der Leuchte nach Anspruch 1 besteht wenigstens ein Teil der Bodenwand der wannenförmigen Abdeckung aus klar durchsichtigem Material, wobei zwischen der Abdeckung und dem Basisteil ein Raster angeordnet ist. Die klar durchsichtige Bodenwand ermöglicht eine größere Abstrahlleistung, wobei das Raster die Leuchte entblendet. Der zu beleuchtende Raum wird bei der erfindungsgemäßen Leuchte folglich mit einer größeren Leuchtdichte beleuchtet, wobei eine Person in dem beleuchteten Raum bei üblichem Blickwinkel von dem abgestrahlten Licht hinsichtlich einer Blendung weitgehend unbeeinträchtigt bleibt. Die erfindungsgemäße Leuchte eignet sich somit bei einfacher, kleiner und kostengünstiger Ausgestaltung für anspruchsvolle Beleuchtungszwecke, z. B. in Wohnräumen, Büros und dgl. Der Erfindung liegt die Erkenntnis zugrunde, daß sich die wannenförmige Abdeckung bei guter Raumausnutzung zur Aufnahme des Rasters vorzüglich eignet. Dabei kann das Raster an der Bodenwand der wannenförmigen Abdeckung anliegen, wodurch die Positionierung des Rasters wesentlich einfacher ist.In the luminaire according to claim 1, at least a part of the bottom wall of the trough-shaped cover consists of clear, transparent material, a grid being arranged between the cover and the base part. The clear, transparent bottom wall enables a greater radiation output, with the grid glare-free from the lamp. The space to be illuminated is consequently illuminated with a greater luminance in the luminaire according to the invention, a person in the illuminated space remaining largely unaffected by the emitted light with respect to glare at the usual viewing angle. The lamp according to the invention is therefore suitable for simple lighting, small and inexpensive design for demanding lighting purposes, for. B. in living rooms, offices and the like. The invention is based on the knowledge that the trough-shaped cover is excellent for taking up the grid with good use of space. The grid on the bottom wall of the trough-shaped Cover cover, which makes positioning the grid much easier.

Im Rahmen der Erfindung können sich die Seitenwände der Leuchte bezüglich deren vertikalen Mittelebene parallel oder zum Basisteil hin konvergent erstrecken. Die letztere Ausgestaltung hat den Vorteil, daß eine vergrößerte Lichtabstrahlung zur Anbauseite der Leuchte erreicht wird. Hierdurch wird die Umgebung der Leuchte an der Anbauseite, z. B. einer Decke, vermehrt ausgeleuchtet, und es wird der Helligkeitsunterschied zwischen der Leuchte und ihrer Umgebung vermindert, was zwecks Verringerung von Beleuchtungskontrasten im weiteren auch angestrebt wird.In the context of the invention, the side walls of the luminaire can extend parallel to the base part or converge towards the base part. The latter embodiment has the advantage that an increased light radiation to the mounting side of the lamp is achieved. As a result, the environment of the lamp on the mounting side, for. B. a ceiling, increasingly illuminated, and the difference in brightness between the lamp and its surroundings is reduced, which is also aimed at in order to reduce lighting contrasts in the further.

Die der Erfindung zugrundeliegende Aufgabe wird auch durch die Ausgestaltung nach Anspruch 7 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in zugehörigen Unteransprüchen beschrieben.The object on which the invention is based is also achieved by the configuration according to claim 7. Advantageous developments of the invention are described in the associated subclaims.

Bei der Ausgestaltung nach Anspruch 7 weist die wannenförmige Abdeckung an ihrem dem Basisteil zugewandten Rand sich von den Seitenwänden nach innen erstreckende Deckenwandabschnitte auf, denen im Basisteil gegenüberliegend seitlich offene Ausnehmungen angeordnet sind. Bei dieser Ausgestaltung ist die Abstrahlfläche der Leuchte um die Flächengröße der Ausnehmungen nicht nur vergrößert, so daß mehr Licht abgestrahlt wird, sondern die vergrößerten Flächenbereiche sind auch zur Anbauseite, z. B. zur Decke, hin gerichtet. Hierdurch wird die Umgebung der Leuchte im Bereich der Anbauseite vermehrt beleuchtet und folglich werden die bezüglich den divergenten Seitenwänden bereits genannten Vorteile erreicht, auf die zwecks Vermeidung von Wiederholungen Bezug genommen wird.In the embodiment according to claim 7, the trough-shaped cover has, at its edge facing the base part, ceiling wall sections which extend inwards from the side walls and which are arranged in the base part on the opposite side with open recesses. In this embodiment, the radiation area of the lamp is not only increased by the area size of the recesses, so that more light is emitted, but the enlarged areas are also to the mounting side, for. B. towards the ceiling. As a result, the area surrounding the luminaire is increasingly illuminated in the area of the installation side, and consequently the advantages already mentioned with regard to the divergent side walls are achieved, to which reference is made to avoid repetition.

Weiterbildungen der Erfindung führen zu einfachen, kleinen und kostengünstig herstellbaren Bauweisen, wobei auch die Befestigung des Rasters und/oder der wannenförmigen Abdeckung verbessert werden.

Die Hauptteile der in ihrer Gesamtheit mit 1 bezeichneten Leuchte sind ein sockelförmiges Basisteil 2 mit vereinfacht dargestellten Befestigungsmitteln 3 zum Befestigen des Basisteils 2 an der Anbauseite 4 eines Anbaukörpers, z. B. einer Decke oder einer Wand, eine wannenförmige Abdeckung 5, die durch Befestigungsmittel 6 an der der Anbauseite 4 abgewandten Seite des Basisteils 2 mit diesem lösbar verbindbar ist, einem Raster 7, das zwischen dem Basisteil 2 und der Bodenwand 5a der Abdeckung 5 angeordnet ist und weiteren, insbesondere durch wenigstens eine Steckfassung gebildeten Befestigungsmitteln 8 zur Halterung und elektrischen Verbindung von einer mittig oder zwei nebeneinander angeordneten Lampen 9 sowie weiteren üblichen Betriebsmitteln zur elektrischen Stromversorgung.The main parts of the lamp designated in its entirety with 1 are a pedestal-shaped base part 2 with fastening means 3 shown in simplified form for fastening the base part 2 to the attachment side 4 of an attachment, for. B. a ceiling or a wall, a trough-shaped cover 5, which can be detachably connected to the base part 2 facing away from the attachment side 4 by fastening means 6, a grid 7, which is arranged between the base part 2 and the bottom wall 5a of the cover 5 and further fastening means 8, in particular formed by at least one plug-in socket, for holding and electrically connecting a lamp 9 arranged in the middle or two next to one another and further conventional operating means for the electrical power supply.

Die vorzugsweise längliche Leuchte 1 weist eine im wesentlichen rechteckige oder quadratische Querschnittsform auf, wobei sie auch unter Berücksichtigung ihrer sich rechtwinklig zur Längsmittelachse erstreckenden Stirnseiten die Form eines Rechteckquaders aufweist. Die vorzugsweise ebenen Seitenwände 5b und gegebenenfalls auch die vorzugsweise ebenen Stirnwände 5c der Abdeckung 5 können sich in Richtung auf das Basisteil 2 auch konvergent erstrecken, wie es in Fig. 2 angedeutet ist.The preferably elongated luminaire 1 has an essentially rectangular or square cross-sectional shape, wherein it also has the shape of a rectangular cuboid, taking into account its end faces extending at right angles to the longitudinal central axis. The preferably flat side walls 5b and possibly also the preferably flat end walls 5c of the cover 5 can also extend convergingly in the direction of the base part 2, as is indicated in FIG. 2.

Das Basisteil 2 ist mit einem an der der Abdeckung 5 zugewandten Seite umlaufend ausgebildeten Ringvorsprung 2a im Längs- und Querschnitt U-förmig ausgebildet, wobei der Hohlraum dieser U-Form mit 11 bezeichnet ist.The base part 2 is U-shaped in the longitudinal and cross-section with an annular projection 2a formed on the side facing the cover 5, the cavity of this U-shape being designated by 11.

Beim Ausführungsbeispiel ist das Basisteil 2 ein Blechteil, das einteilig geformt sein kann. Die Abdeckung 5 ist mit der Bodenwand 5a und den Seiten- bzw. Stirnwänden 5b, 5c topfförmig ausgebildet, und sie faßt mit einem Ringstutzen 12 in den Hohlraum 11 ein, wobei zwischen dem Ringstutzen 12 und dem Ringvorsprung 2a ein die Montage bzw. Demontage gewährleistendes Bewegungsspiel vorhanden ist. Die Querschnittsform des Ringstutzens 12 ist an die viereckige Querschnittsform des Ringvorsprungs 2a angepaßt. Der Ringstutzen 12 ist somit bezüglich den Außenseiten der Abdeckung 5 um das Maß der Dicke d des Ringvorsprungs 2a verjüngt. In diesem Verjüngungsbereich erstreckt sich an einander gegenüberliegenden Seiten, hier den Längsseiten (s. Fig. 1), oder auf dem gesamten Umfang ein ringförmiger Deckenwandabschnitt 5d einteilig von der zugehörigen Seiten- bzw. Stirnwand 5b, 5c zur Ringwand 12a des Ringstutzens 12. Der Ringvorsprung 2a liegt somit dem Deckenwandabschnitt 5d gegenüber. Die Befestigungsmittel 6 können z. B. durch Verrastungsvorrichtungen 13 gebildet sein, die zwischen dem Ringstutzen 12 und dem Ringvorsprung 2a wirksam sind und durch vorzugsweise am Ringvorsprung 2a befestigte Rastnasen 13a gebildet sein können, die jeweils einen Rastvorsprung 13b am Ringstutzen 12 mit einer elastischen Kraft hintergreifen. Beim Montieren des Anbauteils 5 durch Einstecken weichen die z. B. an Federarmen angeordneten Rastnasen 13a selbsttätig aus und schnappen hinter den Rastvorsprüngen 13b selbsttätig ein, wodurch die Abdeckung 5 am Basisteil 2 lösbar fixiert ist. Vorzugsweise ist die Verrastungsvorrichtung 13 zum Lösen der Abdeckung 5 durch eine manuell an ihr ausgeübte Zugkraft lösbar, wobei die Rastnasen 13a selbsttätig ausweichen. Für eine sichere Fixierung reichen zwei einander gegenüberliegend und mittig angeordnete Verrastungsvorrichtungen 13 aus. Bei der vorliegenden länglichen Bauweise ist es vorteilhaft, in jedem Endbereich zwei einander gegenüberliegend angeordnete Verrastungsvorrichtungen 13 vorzusehen.In the exemplary embodiment, the base part 2 is a sheet metal part, which can be formed in one piece. The cover 5 is cup-shaped with the bottom wall 5a and the side or end walls 5b, 5c, and it surrounds with an annular connector 12 into the cavity 11, with an assembly or disassembly ensuring between the annular connector 12 and the annular projection 2a Movement play is present. The cross-sectional shape of the ring socket 12 is adapted to the square cross-sectional shape of the ring projection 2a. The ring neck 12 is thus tapered with respect to the outer sides of the cover 5 by the amount of the thickness d of the ring projection 2a. In this tapering area, on opposite sides, here the long sides (see FIG. 1), or on the entire circumference, an annular ceiling wall section 5d extends in one piece from the associated side or end wall 5b, 5c to the ring wall 12a of the ring connector 12. The Ring projection 2a thus lies opposite the ceiling wall section 5d. The fasteners 6 can, for. B. be formed by latching devices 13, which are effective between the ring socket 12 and the ring projection 2a and may be formed by preferably on the ring projection 2a attached locking lugs 13a, each of which engages behind a locking projection 13b on the ring socket 12 with an elastic force. When mounting the attachment 5 by inserting the z. B. on spring arms arranged locking lugs 13a automatically and snap behind the locking projections 13b automatically, whereby the cover 5 is releasably fixed to the base part 2. The latching device 13 is preferably releasable for releasing the cover 5 by means of a manually applied tensile force, the latching lugs 13a automatically deflecting. For a secure fixation, two locking devices 13 arranged opposite one another and in the center are sufficient. In the present elongated construction, it is advantageous to provide two locking devices 13 arranged opposite one another in each end region.

Das aus Blech geformte Basisteil 2 weist einen den Hohlraum 11 oberseitig begrenzenden Deckenwandabschnitt 2b und innen- sowie außenseitige Seitenwandabschnitte 2c, 2d auf, die kastenförmig miteinander verbunden sind. Der äußere Seitenwandabschnitt 2d überragt den Deckenwandabschnitt 2b zur Anbauseite 4 hin. Von seinem freien Rand kann sich ein kurzer Flanschabschnitt 2e nach innen erstrecken, wodurch der Seitenwandabschnitt 2d stabilisiert wird. In dem sich zwischen dem freien Rand des äußeren Seitenwandabschnitts 2d und dem Deckenwandabschnitt 2b vorhandenen Hohlraum 14 kann sich eine Einbuchtung 2f des Deckenwandabschnitts 2b erstrecken, wodurch ein nach oben vergrößerter Freiraum 11 für elektrische Betriebsmittel und dgl. geschaffen wird, z. B. ein Vorschaltgerät 15, das von unten an dem Deckenwandabschnitt 2b - gegebenenfalls in der Einbuchtung 2f - befestigt ist, z. B. mittels nicht dargestellten Schrauben.The base part 2 formed from sheet metal has a top wall section 2b delimiting the cavity 11 on the top side and side wall sections 2c, 2d on the inside and outside, which are connected to one another in a box-like manner. The outer side wall section 2d projects beyond the ceiling wall section 2b toward the mounting side 4. A short flange portion 2e may extend inward from its free edge, thereby stabilizing the side wall portion 2d. In which itself An indentation 2f of the ceiling wall section 2b can extend between the free edge of the outer side wall section 2d and the ceiling wall section 2b, thereby creating an upwardly enlarged space 11 for electrical equipment and the like. B. a ballast 15, which is attached to the ceiling wall section 2b from below - optionally in the indentation 2f, for. B. by means of screws, not shown.

Im Basisteil 2 ist an wenigstens einer Seite, hier an beiden Längsseiten eine Ausnehmung 16 vorgesehen, die seitlich sowie zur Abdeckung 5 hin offen ist und beim Ausführungsbeispiel durch zwei winkelförmige Wandabschnitte 2h, 2i begrenzt ist, von denen sich der Wandabschnitt 2h an oder in einem geringen Abstand vom inneren Seitenwandabschnitt 2c erstreckt und somit den Abstand a an der Außenseite aufweist und der Wandabschnitt 2i den Abstand b von der Stirnseite des Ringvorsprungs 2a Deckenwandabschnitt 5d aufweist und sich beim Ausführungsbeispiel etwa auf halber Höhe des Basisteils 2 befindet. Der Abstand a beträgt vorzugsweise etwa 5 mm bis 20 mm. Ein Abstand a von etwa 12 mm ist unter Berücksichtigung vorgegebener Raumverhältnisse und Außenabmessungen der Leuchte 1 besonders vorteilhaft. Der Abstand b beträgt vorzugsweise ebenfalls wenigstens etwa 5 mm und er ist insbesondere geringer bemessen als die Höhe h des Basisteils 2, wodurch das Basisteil 2 an der Anbauseite 4 die Form eines stabilen Sockels erhält.In the base part 2, a recess 16 is provided on at least one side, here on both longitudinal sides, which is open laterally and towards the cover 5 and, in the exemplary embodiment, is delimited by two angular wall sections 2h, 2i, of which the wall section 2h is located on or in one extends a small distance from the inner side wall section 2c and thus has the distance a on the outside and the wall section 2i has the distance b from the end face of the ring projection 2a ceiling wall section 5d and in the exemplary embodiment is located approximately halfway up the base part 2. The distance a is preferably about 5 mm to 20 mm. A distance a of about 12 mm is particularly advantageous, taking into account the given spatial conditions and external dimensions of the lamp 1. The distance b is also preferably at least about 5 mm and is in particular smaller than the height h of the base part 2, as a result of which the base part 2 is given the shape of a stable base on the attachment side 4.

Bei dem Raster 7 handelt es sich um eine an sich bekannte Bauweise mit zwei einander gegenüberliegenden Reflexionsseitenwänden 17, die bezüglich einer zur Anbauseite 4 rechtwinklig gerichteten Längsmittelebene E symmetrisch angeordnet und geformt sind, und mit sich dazwischen quer erstreckenden aufrechten Rasterwänden 18, die durch an sich bekannte Befestigungsmittel 19 mit den Reflexionsseitenwänden 17 verbunden sind, und deren Höhe geringer als die Höhe der Reflexionsseitenwände 17 bemessen ist, so daß die wenigstens eine Lampe 9 zwischen den einen Längsabstand c voneinander aufweisenden Rasterwänden 18 und den oberen Rändern der Reflexionsseitenwände 17 angeordnet ist. Das Raster 7 ist vorzugsweise an der Abdeckung 5 positioniert oder fixiert. Für eine Deckenleuchte reicht eine Positionierung - hier in der Mitte - in der Abdeckung 5 aus, da das Raster 7 aufgrund der Schwerkraft an der Bodenwand 5a anliegen kann. Zur Positionierung in der Mitte können von den unteren Rändern der Reflexionsseitenwände 17 nach außen abstehende Positionierarme 21 vorgesehen sein, die sich bis zu den Seitenwänden 5b erstrecken. Die Länge der Positionierarme 21 ist so groß bemessen, daß das Raster 7 durch Schrägstellung aus der verjüngten Öffnung 5e der Abdeckung 5 einsetzbar bzw. entnehmbar ist. Die Positionierarme 21 können auch elastisch biegbar sein, so daß das Einsetzen bzw. Entnehmen des Rasters im verjüngten Öffnungsbereich möglich ist. Das Raster 7 kann auch an der Abdeckung 5 befestigt sein, z. B. durch Verkleben des unteren Randbereichs der Reflexionsseitenwände 17 mit der Bodenwand 5a, wobei dieser Randbereich durch einen unteren, sich nach außen etwa parallel zur Bodenwand 5a erstreckenden Seitenwandschenkel 17a und einen sich von dessen äußeren Rand nach oben erstreckenden Seitenwandschenkel 17b gebildet sein kann. Die Positionierarme 21 können sich vom freien Rand des Seitenwandschenkels 17b zur zugehörigen Seitenwand 5b erstrecken, wobei sie mit einer seitlichen Druckspannung an diesen anliegen können, wodurch eine Klemmvorrichtung zur Positionierung des Rasters 7 der Abdeckung 5 gebildet ist. Bei einer solchen oder anderen Befestigungsvorrichung für das Raster 7 in der Abdeckung 5 eignet sich die Leuchte 1 auch für eine um etwa 90 ° verdrehte Anbringung, z. B. an einer Wand. Eine Befestigung des Rasters in der Abdeckung 5 kann bei einer Vorfertigung erfolgen, so daß bei der Montage die Abdeckung 5 und das Raster 7 zusammen montiert werden können.The grid 7 is a construction known per se with two mutually opposite reflection side walls 17, which are arranged and shaped symmetrically with respect to a longitudinal center plane E directed at right angles to the mounting side 4, and with upright grid walls 18 extending transversely therebetween, which by themselves Known fastening means 19 are connected to the reflection side walls 17, and the height of which is less than the height of the reflection side walls 17, so that the at least one lamp 9 is arranged between the grid walls 18 having a longitudinal distance c from one another and the upper edges of the reflection side walls 17. The grid 7 is preferably positioned or fixed on the cover 5. For a ceiling light, one positioning - here in the middle - in the cover 5 is sufficient, since the grid 7 can rest against the bottom wall 5a due to gravity. For positioning in the middle, positioning arms 21 projecting outwards from the lower edges of the reflection side walls 17 can be provided, which extend up to the side walls 5b. The length of the positioning arms 21 is so large that the grid 7 can be inserted or removed from the tapered opening 5e of the cover 5 by inclination. The positioning arms 21 can also be elastic be bendable, so that the insertion or removal of the grid in the tapered opening area is possible. The grid 7 can also be attached to the cover 5, for. B. by gluing the lower edge region of the reflection side walls 17 to the bottom wall 5a, wherein this edge region can be formed by a lower side wall leg 17a extending outward approximately parallel to the bottom wall 5a and a side wall leg 17b extending upward from the outer edge thereof. The positioning arms 21 can extend from the free edge of the side wall limb 17b to the associated side wall 5b, whereby they can bear against them with a lateral compressive stress, whereby a clamping device for positioning the grid 7 of the cover 5 is formed. In such or another fastening device for the grid 7 in the cover 5, the lamp 1 is also suitable for an attachment rotated by approximately 90 °, e.g. B. on a wall. An attachment of the grid in the cover 5 can be done in a prefabrication, so that the cover 5 and the grid 7 can be assembled together during assembly.

Das Basisteil 2 besteht vorzugsweise aus einem sich über den Großteil der Längsabmessung erstreckenden Profilabschnitt 22 und gleichen und/oder spiegelbildlich zueinander angeordneten Endteilen 23, die durch nicht dargestellte Verbindungsvorrichtungen mit dem zugehörigen Ende des Profilabschnitts 22 verbunden sind, z. B. mittels längs des Profils zusammensteckbaren Steckvorrichtungen. Beim Ausführungsbeispiel weisen die Endteile 23 in Richtung auf den Profilabschnitt 22 vorstehende Endteilschenkel 23a auf, die durch einen Endteilsteg 23b miteinander verbunden sind. Die Verbindungsvorrichtungen zwischen den Endteilschenkeln 23a und dem Profilabschnitt 2 sind aus Vereinfachungsgründen nicht dargestellt. Im Bereich der Endteile 23 erstrecken sich der Hohlraum 11 und der Ringstutzen 12 bis zu den Endteilstegen 23b, die schmaler als die Endteilschenkel 23b bemessen sein können, wie es Fig. 3 zeigt.The base part 2 preferably consists of a profile section 22 which extends over the majority of the longitudinal dimension and the same and / or mirror images of end parts 23 which are connected to the associated end of the profile section 22 by connecting devices, not shown, for. B. by means of pluggable connectors along the profile. In the exemplary embodiment, the end parts 23 have end part legs 23a projecting in the direction of the profile section 22, which are connected to one another by an end part web 23b. The connection devices between the end part legs 23a and the profile section 2 are not shown for reasons of simplification. In the region of the end parts 23, the cavity 11 and the ring connector 12 extend to the end part webs 23b, which can be dimensioned narrower than the end part legs 23b, as shown in FIG. 3.

Die Ausbildung des Basisteils 2 aus dem Längsabschnitt 22 und den Endteilen 23 ist aus mehreren Gründen vorteilhaft. Zum einen ist es möglich, den Längsabschnitt 22 als Profil auszubilden bzw. vorzufertigen, z. B. als Strangpreßprofil oder auch als Blechprofil, das abgekantet oder im Zuge eines Durchlaufs gewalzt bzw. geformt sein kann. Hierdurch wird eine einfache und preiswerte Herstellung für den Längsabschnitt 22 erreicht. Dieser kann somit z. B. aus Kunststoff oder Metallblech wie Stahlblech oder Aluminiumblech, bestehen. Beim Ausführungsbeispiel erstrecken sich die Ausnehmungen 16 nur im Bereich des Längsabschnitts 22, d. h. in den Endteilen 23 sind die Ausnehmungen 16 nicht vorhanden.The formation of the base part 2 from the longitudinal section 22 and the end parts 23 is advantageous for several reasons. On the one hand, it is possible to form or prefabricate the longitudinal section 22 as a profile, eg. B. as an extruded profile or as a sheet metal profile, which can be folded or rolled or shaped in one pass. This achieves simple and inexpensive production for the longitudinal section 22. This can thus z. B. made of plastic or sheet metal such as steel sheet or aluminum sheet. In the exemplary embodiment, the recesses 16 extend only in the region of the longitudinal section 22, ie the recesses 16 are not present in the end parts 23.

Ein weiterer Vorteil besteht darin, daß mehrere Längsabschnitte 22 sich stapeln lassen, wie es Fig. 4 zeigt. Im Bereich der Vorfertigung lassen sich somit mehrere oder eine Vielzahl Längsabschnitte 22 bei verringertem Raumbedarf lagern und deshalb auch günstig transportieren.Another advantage is that several longitudinal sections 22 can be stacked, as shown in FIG. 4. In the area of prefabrication, several or a plurality of longitudinal sections 22 can thus be stored with a reduced space requirement and can therefore also be transported cheaply.

Fig. 5 zeigt eine gleichfalls vorteilhafte Alternative für das Basisteil 2 und/oder den Längsabschnitt 22. Bei dieser Ausgestaltung ist die Deckenwand 2b durch einen z. B. sich vertikal erstreckenden Verbindungsschenkel 2j mit dem Flanschabschnitt 2e zu einer Kastenform verbunden. Der innenseitige Seitenwandabschnitt 2c fehlt dagegen, wobei beim Ausführungsbeispiel sich vom Wandabschnitt 2h ein Innenschenkel 2k nach innen erstreckt, z. B. U-förmig.Fig. 5 shows an equally advantageous alternative for the base part 2 and / or the longitudinal section 22. In this embodiment, the top wall 2b is by a z. B. vertically extending connecting leg 2j connected to the flange portion 2e into a box shape. The inner side wall section 2c, on the other hand, is absent. In the exemplary embodiment, an inner leg 2k extends inward from the wall section 2h, e.g. B. U-shaped.

Die Stapelbarkeit ist bei beiden Profilformen gewährleistet, weil der Abstand a unter Berücksichtigung eines Bewegungsspiels größer ist als die Abmessung des Flanschabschnitts 2e beim Ausführungsbeispiel nach Fig. 2 und 4 oder die Abmessung e des nach oben weisenden Sockelringes 24. Die Endteile 23 können auch beim Ausführungsbeispiel nach Fig. 5, wie vorbeschrieben, ausgebildet sein.The stackability is ensured in both profile shapes because the distance a, taking into account a play of movement, is greater than the dimension of the flange section 2e in the exemplary embodiment according to FIGS. 2 and 4 or the dimension e of the base ring 24 pointing upward. The end parts 23 can also be used in the exemplary embodiment 5, as described above, be formed.

Die Bodenwand 5a der Abdeckung 5 besteht wenigstens im Bereich des beim vorliegenden Ausführungsbeispiel durch ein Raster 7 gebildeten Reflektors 7a oder im gesamten Bodenwandbereich aus klar lichtdurchlässigem Material wie Glas oder Kunststoff. Hierdurch gibt die Leuchte 1 im Funktionsbetrieb ein Licht mit hoher Leuchtdichte in der durch den Pfeil 25 verdeutlichten, quer zur Bodenwand 5a gerichteten Hauptabstrahlrichtung ab. Die Seitenwände 5b können aus klar durchsichtigem oder durchscheinendem (opalem) Material bestehen. In beiden Fällen ist die Leuchte 1 bzw. die Abdeckung 5 somit geeignet, durch den Pfeil 26 vereinfacht dargestelltes Seitenlicht abzustrahlen, das aus Lichtstrahlen gebildet ist, die von der wenigstens einen Lampe 9 durch den sich zwischen den oberen Rändern der Reflexionsseitenwände 17 erstreckenden Abstand f in den Raum oberhalb des Reflektors 7a erstrecken und von dem sich darüber befindlichen Freiraum 27 seitlich nach außen gelangen. Hierzu kann eine Reflexion dieser Lichtstrahlen an der Innenseite der Deckenwand 2b beitragen, deren Innenseite vorzugsweise als Reflexionsfläche ausgebildet ist. Hierbei wird ein Anteil 26a des Seitenlichts auch schräg aufwärts durch die Deckenwandabschnitte 5e abgestrahlt, was zur weiteren Beleuchtung der seitlichen Umgebung der Leuchte 1 beiträgt, insbesondere im Bereich der Anbauseite 4. Auch die Seitenwände 5b einschließlich den sich außerhalb des Reflektors 7a befindlichen Bodenwandabschnitten 5a1 und die Deckenwandabschnitte 5d können aus klar durchsichtigem oder durchscheinendem (opalem) Material bestehen.The bottom wall 5a of the cover 5 consists, at least in the region of the reflector 7a formed by a grid 7 in the present exemplary embodiment, or in the entire bottom wall region of clearly transparent material such as glass or plastic. As a result, the luminaire 1 emits a light with a high luminance in functional mode in the main emission direction, illustrated by the arrow 25 and directed transversely to the base wall 5a. The side walls 5b can consist of clearly transparent or translucent (opal) material. In both cases, the luminaire 1 or the cover 5 is thus suitable for emitting side light, represented in a simplified manner by the arrow 26, which is formed from light beams which are emitted from the at least one lamp 9 by the distance f extending between the upper edges of the reflection side walls 17 extend into the space above the reflector 7a and move laterally outwards from the free space 27 located above it. A reflection of these light rays on the inside of the ceiling wall 2b, the inside of which is preferably designed as a reflection surface, can contribute to this. Here, a portion 26a of the side light is also emitted obliquely upwards through the ceiling wall sections 5e, which contributes to further illumination of the lateral surroundings of the lamp 1, in particular in the area of the attachment side 4. The side walls 5b including the bottom wall sections 5a1 and 6 located outside the reflector 7a the ceiling wall sections 5d can consist of clearly transparent or translucent (opal) material.

Die Leuchte 1 kann durch die Abstrahlung von farbigem Seitenlicht 26 spezifiziert und an besondere Bedürfnisse und Raumeinrichtungen angepaßt werden. Es kann der stufenförmige Absatz, mit dem die Abdeckung 5 an dem Basisteil 2 befestigt ist, hier die Ringstutzenwand 12a und/oder die Deckenwandabschnitte 5d, gefärbt sein.The lamp 1 can be specified by the emission of colored side light 26 and adapted to special needs and room furnishings. The step-shaped heel with which the cover 5 is fastened to the base part 2, here the annular connecting piece wall 12a and / or the ceiling wall sections 5d, can be colored.

Eine andere Ausgestaltung zur Erzeugung von farbigem Seitenlicht 26 bzw. 26a kann durch die Anordnung eines sich quer zum Seitenlicht 26 erstreckenden Farbfilters 28 im Hohlraum 5e erzeugt werden. Das Farbfilter 28 kann z. B. durch eine Folie aus vorzugsweise steifem Material gebildet sein, die sich schräg zwischen dem oberen Randbereich der Reflexionsseitenwände 17 und dem Eckenbereich des Hohlraums 11 erstreckt und das Seitenlicht 26 färbt. Zur formschlüssigen Halterung des Farbfilters 28 kann jeweils am oberen Rand der Reflexionsseitenwände 17 ein kleiner Querschenkel (nicht dargestellt) angeformt sein, der in Verbindung mit dem Eckenbereich des Hohlraums 11 eine formschlüssige Halterung gewährleistet.Another embodiment for generating colored side light 26 or 26a can be produced by arranging a color filter 28 extending transversely to the side light 26 in the cavity 5e. The color filter 28 can e.g. B. be formed by a film of preferably rigid material which extends obliquely between the upper edge region of the reflection side walls 17 and the corner region of the cavity 11 and colors the side light 26. For the form-fitting mounting of the color filter 28, a small cross leg (not shown) can be formed on the upper edge of the reflection side walls 17, which ensures a form-fitting mounting in connection with the corner region of the cavity 11.

Die Farbe des Seitenlichts 26 bzw. auch 26a kann z. B. grün, blau, gelb oder rot sein.The color of the side light 26 or 26a can, for. B. be green, blue, yellow or red.

Die Leuchte 1 strahlt somit gerichtetes Licht 25 nach unten und Seitenlicht 26 bzw. 26a gleicher bzw. weißer Farbe oder farbiges Licht zur Seite ab, um die Umgebung und den Bereich der Anbauseite mit zu beleuchten.The luminaire 1 thus radiates directed light 25 downward and side light 26 or 26a of the same or white color or colored light to the side in order to illuminate the surroundings and the area of the attachment side.
