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 over the majority of Longitudinally extending profile section 22 and the same and / or mirror images of each other arranged end portions 23, by not shown Connecting devices with the associated end of the profile section 22nd are connected, z. B. can be joined together by means of the profile Plugs and sockets. In the embodiment, the end portions 23 in the direction on the profile section 22 protruding Endteilschenkel 23 a, which by a End part web 23b are interconnected. The connection devices between the Endteilschenkeln 23 a and the profile section 2 are made Simplification reasons not shown. In the region of the end portions 23 extend the cavity 11 and the annular nozzle 12 to the end part webs 23b, the narrower as the Endteilschenkel 23 b may be sized, 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 portion 22 and the end portions 23 is advantageous for several reasons. On the one hand, it is possible, the longitudinal section 22nd train as a profile or prefabricate, z. B. as extruded or as Sheet metal profile, the folded or rolled or formed in the course of a run can be. This is a simple and inexpensive production for the Longitudinal section 22 is reached. This can thus z. B. plastic or sheet metal like sheet steel or aluminum sheet. In the embodiment the recesses 16 extend only in the region of the longitudinal section 22, d. H. in the end portions 23, the recesses 16 are not present.

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 are stacked let, as shown in FIG. 4 shows. In the field of prefabrication can thus be more or store a plurality of longitudinal sections 22 in a reduced space requirement and Therefore also transport cheap.

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 ceiling wall 2b by a z. B. vertically extending connecting leg 2j with the flange portion 2e connected to a box shape. The inside side wall portion 2c is missing whereas, in the embodiment, from the wall section 2h Inner leg 2k extends inwards, z. 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 below Considering a movement game is greater than the dimension of Flange section 2e in the embodiment of FIGS. 2 and 4 or the Dimension e of the upwardly facing base ring 24. The end portions 23 can also in the embodiment of FIG. 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 5d 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 is at least in the area of the present embodiment by a grid 7 formed reflector 7a or in the entire bottom wall area of clear translucent material such as glass or Plastic. As a result, the lamp 1 in the function mode, a light with high Luminance in the illustrated by the arrow 25, transverse to the bottom wall 5a directed main emission. The side walls 5b may be clear transparent or translucent (opal) material. In both cases is the lamp 1 and the cover 5 thus suitable, by the arrow 26th to radiate simplified sidelight, which is formed by light beams, that of the at least one lamp 9 through which between the upper edges the reflection side walls 17 extending distance f in the space above the Reflectors extend 7a and from the overlying space 27 laterally get outside. For this purpose, a reflection of these light rays at the Inside the ceiling wall contribute 2b, the inside preferably as Reflection surface is formed. Here, a portion 26a of the side light also becomes obliquely upward radiated through the ceiling wall portions 5d, resulting in the further Lighting the lateral environment of the lamp 1 contributes, especially in Area of the mounting side 4. Also the side walls 5b including the itself outside the reflector 7a located bottom wall portions 5a1 and the Ceiling wall portions 5d may be made of clear 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 luminaire 1 can be specified by the emission of colored side light 26 and adapted to special needs and room facilities. It can be the stepped shoulder, with which the cover 5 is fixed to the base part 2, here the annular nozzle wall 12a and / or the ceiling wall sections 5d, 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 and 26a can by the arrangement of a color filter 28 extending transversely to the side light 26 be generated in the cavity 5e. The color filter 28 may, for. B. through a film preferably be formed rigid material, which extends obliquely between the upper Edge region of the reflection side walls 17 and the corner region of the cavity 11 extends and the side light 26 colors. For positive retention of the color filter 28 may each at the top of the reflection side walls 17 a smaller Transverse leg (not shown) formed in conjunction with the Corner region of the cavity 11 ensures a positive fit.

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

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 lamp 1 thus emits directed light 25 down and sidelight 26 or 26a same or white color or colored light to the side off to the environment and to illuminate the area of the mounting side with.
