Description

Die Erfindung bezieht sich auf eine Leuchte nach dem Oberbegriff des Anspruches 1.The invention relates to a lamp according to the preamble of claim 1.

Die Beleuchtung eines Raumes kann aus praktischen und/oder ästhetischen Gründen von Bedeutung sein. Bei der Beleuchtung eines für den Aufenthalt von Menschen eingerichteten Raumes können beide vorgenannten Gründe relevant sein. Bei Leuchten für untergeordnete Räume, z.B. Kellerräume oder einfache Arbeitsräume, liegt in den meisten Fällen die Forderung nach einer guten Ausleuchtung des Raumes im Bereich des Arbeitsplatzes oder des Raumbodens. Dagegen kommt es bei der Beleuchtung von Wohnräumen oder der Repräsentation dienenden Räumen, z.B. Empfangsräumen, auch auf die ästhetische Wirkung der Beleuchtung an.The lighting of a room can be important for practical and / or aesthetic reasons. Both of the above-mentioned reasons can be relevant when illuminating a room furnished for the stay of people. For luminaires for subordinate rooms, e.g. Basement rooms or simple work rooms, in most cases there is a requirement for good lighting of the room in the area of the workplace or the floor of the room. On the other hand, there is lighting in living rooms or representative rooms, e.g. Reception rooms, also on the aesthetic effect of the lighting.

Dabei sind sowohl direkt als auch indirekt wirksame Leuchten bekannt geworden, bei denen die Beleuchtung des Raumes indirekt über eine Begrenzungsfläche des Raumes erfolgt, z.B. eine Decke oder eine Wand.Both directly and indirectly effective luminaires have become known in which the room is illuminated indirectly via a boundary surface of the room, e.g. a ceiling or a wall.

Bei solchen indirekt wirksamen Leuchten kommt es in der Regel hauptsächlich auf den ästhetischen Effekt der Beleuchtung an, wobei die Beleuchtungsleistung eine geringere Rolle spielen kann. Dagegen wird an eine Leuchte für einen untergeordneten Raum, z.B. einen Kellerraum oder einen einfachen Arbeitsraum, hauptsächlich die Forderung nach einer hohen Wirtschaftlichkeit gestellt, um den zugehörigen Raum mit einem möglichst geringen Leistungsverbrauch gut beleuchten zu können. Letzteres gilt insbesondere für Feuchträume, die in vielen Fällen als untergeordnete Räume zu werten sind, und bei denen hauptsächlich mit geringem Energieaufwand eine gute Ausleuchtung des Raumes erreicht werden soll.In the case of such indirectly effective luminaires, the aesthetic effect of the lighting is generally the main factor, with the lighting output being able to play a minor role. In contrast, a luminaire for a subordinate room, e.g. a basement room or a simple work room, mainly the demand for a high level of efficiency in order to be able to illuminate the associated room with the lowest possible power consumption. The latter applies in particular to damp rooms, which in many cases are to be regarded as subordinate rooms and in which good lighting of the room is to be achieved mainly with little energy expenditure.

Es gibt auch Leuchten, die sowohl eine direkte als auch indirekte Beleuchtung des Raumes ermöglichen. Solche Leuchten weisen kein geschlossenes Gehäuse auf, z.B. nur einen oben offenen Schirm, so daß die direkte Beleuchtung durch den Lichtaustrittskegel nach unten und die indirekte Beleuchtung nach oben durch die im Schirm angeordnete Öffnung erfolgt.There are also lights that allow both direct and indirect lighting of the room. Such lights do not have a closed housing, e.g. only one screen open at the top, so that the direct lighting through the light exit cone is down and the indirect lighting is up through the opening in the screen.

Solche und auch andere Leuchten mit einem nicht geschlossenem Gehäuse sind für insbesondere architektonisch anspruchsvoll gestaltete Räume mit feuchter Atmosphäre nicht geeignet, da bei diesen Räumen ein geschlossenes Gehäuse vorhanden sein soll, und zwar um zum einen die wenigstens eine Lampe der Leuchte zu schützen und zum anderen zu verhindern, daß Feuchtigkeit und Verunreinigungen, z.B. Staub, in das Gehäuse hinein gelangen kann.Such and other luminaires with an unclosed housing are not suitable for rooms with a damp atmosphere, in particular architecturally sophisticated, since a closed housing should be present in these rooms to protect the at least one lamp of the lamp and to prevent moisture and contaminants, eg dust, from getting into the housing.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte der eingangs angegebenen Art so auszugestalten, daß die Beleuchtung des Raumes verbessert wird.The invention has for its object to design a lamp of the type mentioned so that the lighting of the room is improved.

Diese Aufgabe wird durch die Merkmale des Anspruches 1 gelöst.This object is solved by the features of claim 1.

Bei der erfindungsgemäßen Leuchte tritt das Licht nicht nur im Bereich der Abdeckung aus, sondern es tritt auch im Bereich des wannenförmigen Gehäusebasisteils aus, wobei der letztere Teil des Lichtes eine die Leuchte tragende Decke oder Wand zu beleuchten vermag, so daß der gesamte Raum heller erscheint.In the luminaire according to the invention, the light not only exits in the area of the cover, but also exits in the region of the trough-shaped housing base part, the latter part of the light being able to illuminate a ceiling or wall carrying the luminaire, so that the entire room appears brighter .

Die erfindungsgemäße Leuchte eignet sich vorzugsweise für solche Räume, bei denen ein geschlossenes Gehäuse (Gehäuse höherer Schutzart) vorgeschrieben ist, wie vorbeschriebene feuchte Räume, z.B. Arbeitsräume, Garagen und dergleichen. Bei solchen Räumen ist die Ausleuchtung verbesserungsbedürftig. Dagegen ermöglicht die Erfindung eine verbesserte Ausleuchtung des vorhandenen Raumes da der Raum nicht nur zu der Seite hin beleuchtet wird, auf der sich die Abdeckung befindet, sondern der Raum wird auch zu der der Abdeckung abgewandten Seite hin beleuchtet, wobei eine zugehörige Decke oder Wand aufgrund ihrer Beleuchtung das Licht zusätzlich zurückstrahlt, was zur bereits beschriebenen Erhellung des Raumes insgesamt und insbesondere im Bereich der die Leuchte tragenden Decke oder Wand führt.The luminaire according to the invention is preferably suitable for rooms in which a closed housing (housing with a higher degree of protection) is prescribed, such as damp rooms described above, e.g. Work rooms, garages and the like. In such rooms, the lighting needs to be improved. In contrast, the invention enables improved illumination of the existing space since the space is not only illuminated towards the side on which the cover is located, but the space is also illuminated towards the side facing away from the cover, with an associated ceiling or wall due to their lighting additionally reflects the light, which leads to the previously described illumination of the room as a whole and in particular in the area of the ceiling or wall supporting the lamp.

In den Unteransprüchen sind Merkmale enthalten, die die Lichtenergie-Ausnutzung und die Raumbeleuchtung weiter verbessern, eine einfache und kostengünstige Bauweise ermöglichen, die Abdichtung des Gehäuses gewährleisten und außerdem eine handhabungsfreundliche Befestigung der Abdeckung am Gehäusebasisteil ermöglichen.The subclaims contain features which further improve the use of light energy and the room lighting, enable a simple and inexpensive construction, ensure the sealing of the housing and also enable the cover to be attached to the housing base part in a manner which is easy to handle.

Die Hauptteile der Leuchte 1 sind ein geschlossenes Gehäuse 2, eine oder mehrere darin angeordnete Fassungen 3 mit elektrischen Kontakten für eine oder mehrere Lampen, insbesondere Leuchtstoffröhren 4 und ein Reflektor 5, der in einer dachförmigen Form und Position über der oder den Lampen im Gehäuse 2 befestigt ist, wobei das bei der vorliegenden Ausgestaltung langgestreckte Gehäuse 2 mit einem Gehäusebasisteil 6 und einer Abdeckung 7 zweiteilig ausgebildet ist und die von der Abdeckung 7 verschlossene Öffnung mit 8 bezeichnet ist. Zwischen dem Gehäusebasisteil 6 und der Abdeckung 7 sind zwei oder mehrere, bei der vorliegenden Ausgestaltung vier Schnellverschlüsse 9 an den Breitseiten des langgestreckten Gehäuses 2 einander gegenüberliegend außen angeordnet.The main parts of the lamp 1 are a closed housing 2, one or more sockets 3 arranged therein with electrical contacts for one or more lamps, in particular fluorescent tubes 4 and a reflector 5, which is in a roof-like shape and position above the lamp or lamps in the housing 2 is fixed, the elongated housing 2 in the present embodiment being formed in two parts with a housing base part 6 and a cover 7 and the opening closed by the cover 7 being designated by 8. Between the housing base part 6 and the cover 7, two or more, in the present embodiment four quick fasteners 9 on the broad sides of the elongated housing 2 are arranged opposite one another on the outside.

Das Gehäusebasisteil 6 weist an seiner der Abdeckung 7 abgewandten Seite einen Fußsockel oder wenigstens zwei vom Gehäusebasisteil 6 vorzugsweise nach oben abstehende, z.B. leistenförmige Füße 10 auf, in deren Bereich oder zwischen denen Durchgangslöcher vorgesehen sind zur Befestigung mittels von innen einsetzbarer Schrauben (nicht dargestellt) an einer Decke oder einer Wand. Die Breite a der Füße ist geringer bemessen als die zugehörige Breite b des Gehäuses 2. Hierdurch ergeben sich zu beiden Seiten der vorzugsweise in den Endbereichen des langgestreckten Gehäuses 2 angeordneten Füße 10 divergente Wandabschnitte 11, die sich bis zur horizontalen Teilung 12 zwischen dem Gehäusebasisteil 6 und der Abdeckung 7 erstrecken. Bei der vorliegenden Ausgestaltung sind die Füße 10 an der Oberseite eines auf dem Kopf stehenden Kastens 13 angeordnet, der sich in der Längsrichtung des langgestreckten Gehäuses 2 mittig erstreckt und dessen Deckwand mit 14, dessen Seitenwände mit 15 und dessen Stirnwände mit 16 bezeichnet sind. Die divergenten Wandabschnitte 11 sind Abschnitte einer im vertikalen Schnitt halbkreisförmigen Form des Gehäusebasisteils 6, an die sich die Form der Abdeckung 7 anschließt, so daß letztere eine entsprechend groß bemessene halbkreisförmige Bodenwand 17 aufweist. Der Kasten 13 ist an beiden Enden des langgestreckten Gehäuses 2 etwas länger bemessen, als die divergenten Wandabschnitte 11, so daß er letztere mit seinen Seitenwänden 15 überragt, und diese sich im Verlängerungsbereich bis in den mittleren Teilungsbereich des Gehäuses 2 erstrecken. In diesen verlängerten Bereichen 18 weist die Abdeckung 7 eine verjüngte Stufe 19 mit einer vorversetzten ringförmigen Stirnwand 21 und der eigentlichen Stirnwand 22 auf.The housing base part 6 has on its side facing away from the cover 7 a base or at least two, for example strip-shaped feet 10, which preferably protrude upward from the housing base part 6, in the area or between which through holes are provided for fastening by means of screws which can be inserted from the inside (not shown). on a ceiling or a wall. The width a of the feet is smaller than the associated width b of the housing 2. This results in divergent wall sections 11 on both sides of the feet 10, which are preferably arranged in the end regions of the elongated housing 2, and which extend as far as the horizontal division 12 between the housing base part 6 and the cover 7 extend. In the present embodiment, the feet 10 are arranged on the top of a box 13 standing upside down, which extends centrally in the longitudinal direction of the elongated housing 2 and whose top wall is designated by 14, its side walls by 15 and its end walls by 16. The divergent wall sections 11 are sections of a semi-circular shape of the housing base part 6 in vertical section, to which the shape of the cover 7 adjoins, so that the latter has a correspondingly large-sized semi-circular bottom wall 17. The box 13 is dimensioned at both ends of the elongated housing 2 somewhat longer than the divergent wall sections 11, so that it projects beyond the latter with its side walls 15, and these extend in the extension area into the central division area of the housing 2. In these extended regions 18, the cover 7 has a tapered one Step 19 with a staggered annular end wall 21 and the actual end wall 22.

Die Abdeckung 7 weist eine umlaufende vertikale Stegwand 23 auf, die in eine umlaufende Rinne 24 in der Form eines auf dem Kopf stehenden U hineinragt. Die Höhe der Stegwand 23 und der Rinne 24 beträgt etwa 15 bis 20 mm. Hierdurch ist ein Labyrinth geschaffen, daß das Gehäuse 2 gegen Feuchtigkeit und Spritzwasser abdichtet. Vorzugsweise ist auch noch eine Dichtungsschnur 24a im Rinnengrund 24a angeordnet. Zur Stabilisierung ist im Bereich der Teilung 12 am Rand der Abdeckung 7 eine zweite, umlaufende Rinne 25 in der Form eines auf dem Kopf stehenden U vorgesehen, von deren Rinnenboden die Stegwand 23 sich nach oben erstreckt. Mit 26 ist eine dichte Kabeldurchführung mit einer elastischen Durchführungstülle in einem Loch der Gehäusewandung, hier der Stirnwand 16 bezeichnet.The cover 7 has a circumferential vertical web wall 23 which projects into a circumferential channel 24 in the form of an upside-down U. The height of the web wall 23 and the groove 24 is approximately 15 to 20 mm. This creates a labyrinth that seals the housing 2 against moisture and splash water. A sealing cord 24a is preferably also arranged in the channel base 24a. For stabilization, a second, circumferential channel 25 in the form of an upside-down U is provided in the region of the division 12 at the edge of the cover 7, from whose channel bottom the web wall 23 extends upwards. With 26 a sealed cable bushing with an elastic grommet in a hole in the housing wall, here the end wall 16 is referred to.

Zur Befestigung der Abdeckung 7 am Gehäusebasisteil 6 sind vier Schnellverschlüsse 9 vorgesehen, die an den Breitseiten des Gehäuses 2 in dessen Endbereich einander gegenüberliegend angeordnet sind. Die Schnellverschlüsse 9 sind vorzugsweise durch einander gleiche C-förmige Spangen 27 gebildet, die mit einem zapfenförmigen Spangenbasisteil 28 in der unteren Rinne 25 sitzen, vorzugsweise darin klemmend gehalten sind, und deren obere krallenförmige Verschlußenden 29 den Boden 24b der oberen Rinne 24 mit Klemmwirkung übergreifen.To fasten the cover 7 on the housing base part 6, four quick-release fasteners 9 are provided, which are arranged on the broad sides of the housing 2 in the end region opposite one another. The quick-release fasteners 9 are preferably formed by mutually identical C-shaped clips 27, which are seated with a pin-shaped clip base part 28 in the lower channel 25, preferably held clamped therein, and whose upper claw-shaped closing ends 29 overlap the bottom 24b of the upper channel 24 with a clamping effect .

Wie insbesondere aus den Figuren 1 und 3 zu entnehmen ist, befinden sich die Fassungen 3 mit von oben nach unten erstreckenden Fassungsstücken 3a im unteren Bereich des Gehäuses 2, d.h. im Bereich der Abdeckung 7. Oberhalb der Lampen bzw. Leuchtstoffröhre 4 ist der Reflektor 5 im Gehäuse 2 angeordnet und gehalten, bei der vorliegenden Ausgestaltung im Bereich der Teilung 12. Der Reflektor 5 ist ein im wesentlichen flacher Körper, vorzugsweise aus Blech, der bei der vorliegenden Ausgestaltung durch eine sich in seine Längsrichtung erstreckende Profilform stabilisiert ist, bei der vorliegenden Ausgestaltung durch endseitige, nach oben gerichtete Abwinkelungsschenkel 32 und vorzugsweise auch eine mittige, nach oben gerichtete Stufe 33, wobei die freien Ränder der Abwinkelungsschenkel 32 rinnenförmig nach unten eingebogen sein können. Die Breite c des Reflektors 5 ist an die Innenbreite d zwischen der Rinne 24 angepaßt. Zur Halterung des Reflektors 5 sind wenigstens zwei Halter 34 am Gehäusebasisteil 6 vorgesehen, die den Reflektor 5 von oben untergreifen. Vorzugsweise sind die beiden Halter 34 im mittleren Bereich der beiden Längshälften vorgesehen. Bei der vorliegenden Ausgestaltung sind die einander gleichen bzw. zueinander spiegelbildlich angeordneten Halter 34 durch horizontal ausbiegbare Verrastungsarme 35 gebildet, die sich von oben nach unten erstrecken, den Reflektor 5 in einem zugehörigen Loch 36 durchfassen und mit einer Verrastungsnase 37 mit Anlaufschrägen 38 den Lochrand untergreifen. Vorzugsweise sind an jeder der vorbeschriebenen zwei Halterungsstellen zwei Verrastungsarme 35 bezüglich der vertikalen Längsmittelebene 39 einander gegenüberliegend angeordnet.As can be seen in particular from FIGS. 1 and 3, the holders 3 with holder pieces 3 a extending from top to bottom are located in the lower region of the housing 2, ie in the region of the cover 7. The reflector 5 is above the lamps or fluorescent tube 4 arranged and held in the housing 2, in the present embodiment in the region of the division 12. The reflector 5 is an essentially flat body, preferably made of sheet metal, which in the present embodiment is stabilized by a profile shape extending in its longitudinal direction, in the present case Design by end-side, upward-pointing bend 32 and preferably also a central, upward step 33, wherein the free edges of the bend 32 can be bent in a groove-like manner downwards. The width c of the reflector 5 is adapted to the inner width d between the channel 24. To hold the reflector 5, at least two holders 34 are provided on the housing base part 6, which engage under the reflector 5 from above. The two holders 34 are preferably provided in the central region of the two longitudinal halves. In the present embodiment, they are each other The same or mirror-inverted holder 34 formed by horizontally bendable locking arms 35 which extend from top to bottom, the reflector 5 in an associated hole 36 and reach under the hole edge with a locking lug 37 with chamfers 38. Preferably, two latching arms 35 are arranged opposite each other with respect to the vertical longitudinal center plane 39 at each of the two mounting points described above.

Die Verrastungsarme 35 sind jeweils an einer vorzugsweise kastenförmigen Halterungsbasis 41 angeformt, die sich im Sinne einer Einziehung von der Deckenwand 14 nach unten erstreckt. An den Verrastungsarmen 35 können bezüglich der Längsmittelebene 39 seitlich abstehende Hakenglieder 42 angeformt sein, denen im Reflektor 5 seitliche Aufstecklöcher 43 zugeordnet sind, und hierdurch ist es möglich, den Reflektor 5 an einer wahlweisen Seite in einer nach unten gekippten Position auf die zugehörigen Hakenglieder 42 aufzustecken. In dieser Position ist das Gehäusebasisteil 6 von unten zugänglich, so daß darin Arbeiten durchgeführt werden können, z.B. Verdrahtungen, Prüfarbeiten oder Austausch an einem Starter 44 oder einem Vorschaltgerät 45 ausgeführt werden können, ohne daß der Reflektor 5 von der Leuchte 1 bzw. vom Gehäusebasisteil 6 völlig entfernt werden muß.The latching arms 35 are each formed on a preferably box-shaped mounting base 41, which extends downward from the ceiling wall 14 in the sense of a retraction. On the latching arms 35 laterally protruding hook members 42 can be formed with respect to the longitudinal center plane 39, to which lateral attachment holes 43 are assigned in the reflector 5, and this makes it possible to place the reflector 5 on an optional side in a downwardly tilted position on the associated hook members 42 put on. In this position the housing base part 6 is accessible from below so that work can be carried out therein, e.g. Wiring, test work or replacement can be carried out on a starter 44 or a ballast 45 without the reflector 5 having to be completely removed from the lamp 1 or from the housing base part 6.

Es ist vorteilhaft, dem Reflektor 5 zusätzliche seitliche Widerlager 46 am Gehäusebasisteil 6 zuzuordnen, die bei der vorliegenden Ausgestaltung durch nach unten gerichtete Enden oder Ausnehmungen von vertikalen Vertiefungen 47 gebildet sein können, an denen die seitlichen Ränder des Reflektors 31 anliegen oder von unten einfassen.It is advantageous to assign additional lateral abutments 46 on the housing base part 6 to the reflector 5, which in the present embodiment can be formed by downwardly directed ends or recesses of vertical recesses 47, against which the lateral edges of the reflector 31 abut or border from below.

Zur Stabilisierung können die Lochränder der Locher 36 nach oben stufenförmig ausgeprägt sein.For stabilization, the hole edges of the holes 36 can be stepped upward.

Wie insbesondere die Figur 1 erkennen läßt, können die Fassungsstücke 3a unterseitig und das Vorschaltgerät 45 und ggf. zugehörige Anschlußklemmen 48 oberseitig am Reflektor 5 befestigt sein (siehe Figuren 1 und 4).As can be seen in particular in FIG. 1, the socket pieces 3a can be fastened on the underside and the ballast 45 and, if appropriate, associated connecting terminals 48 on the top side on the reflector 5 (see FIGS. 1 and 4).

Mit dem Bezugszeichen 51 sind aus dem Reflektor ausgestanzte und ausgebogene Zungen in Längsabständen voneinander vorgesehen, die der Halterung durch Klemmen von Drähten der zugehörigen elektrischen Leitungen dienen. Eine entsprechend ausgeschnittene und ausgebogene Zunge 52 dient zur Halterung eines im weiteren nicht dargestellten Kondensators.With the reference numeral 51 punched out and bent tongues from the reflector are provided at longitudinal distances from each other, which are used for holding by clamping wires of the associated electrical lines. A correspondingly cut and bent tongue 52 is used to hold a capacitor, not shown in the following.

Die Abdeckung 7 besteht wenigstens im der Lampe bzw. Leuchtstoffröhre 4 gegenüberliegenden Bereich aus einem lichtdurchlässigen oder durchsichtigem Material wie Kunststoff oder Glas. Bei der vorliegenden Ausgestaltung ist ein unzerbrechlicher Kuststoff vorgesehen, wie z.B. Polycarbonat. Vorzugsweise besteht die Abdeckung 7 insgesamt aus einem der vorgenannten Materialien. Hierdurch ist nicht nur ein großer Ausbreitungsbereich für das Licht vorhanden, sondern die Abdeckung 7 läßt sich auch als einteiliges Bauteil, insbesondere Kunststoff-Spritzteil einfach und kostengünstig fertigen.The cover 7 consists, at least in the area opposite the lamp or fluorescent tube 4, of a translucent or transparent material such as plastic or glass. In the present embodiment, an unbreakable plastic is provided, e.g. Polycarbonate. The cover 7 preferably consists of one of the aforementioned materials. As a result, not only is there a large propagation area for the light, but the cover 7 can also be produced simply and inexpensively as a one-piece component, in particular a plastic injection-molded part.

Außerdem ist der Reflektor 5 auf wenigstens einem Teilbereich seiner Fläche lichtdurchlässig ausgebildet, hierzu gibt es mehrere Ausgestaltungsmöglichkeiten. Der Reflektor 5 kann auf einem Teilbereich oder insgesamt lichtdurchlässig oder lichtteildurchlässig sein. Im ersteren Fall kann der Reflektor 5 in dem wenigstens einen Bereich oder insgesamt aus lichtdurchlässigem oder durchsichtigem Material bestehen. Im zweiten Fall kann der Reflektor 5 aus lichtundurchlässigem Material bestehen und in dem wenigstens einen Bereich Löcher 53 aufweisen, in deren Bereich das Licht nicht reflektiert wird, sondern durch die Löcher 53 hindurch in das Gehäusebasisteil 6 strahlt.In addition, the reflector 5 is designed to be translucent on at least a portion of its surface; there are several design options for this. The reflector 5 can be translucent or partially translucent over a partial area or as a whole. In the former case, the reflector 5 can consist of translucent or transparent material in the at least one area or as a whole. In the second case, the reflector 5 can consist of opaque material and have holes 53 in the at least one area, in the area of which the light is not reflected, but instead radiates through the holes 53 into the housing base part 6.

Darüberhinaus besteht das Gehäusebasisteil 6 ebenfalls in wenigstens einem Bereich aus wenigstens teilweise lichtdurchlässigem oder durchsichtigem Material, wobei dieser Bereich in der Ausbreitungsrichtung der Strahlen hinter dem wenigstens einen lichtdurchlässigen oder lichtteildurchlässigen Bereich des Reflektors 5 liegt.Furthermore, the housing base part 6 likewise consists of at least partially transparent or transparent material in at least one area, this area lying behind the at least one transparent or partially transparent area of the reflector 5 in the direction of propagation of the rays.

Bei dem vorbeschriebenen Bereich oder den vorbeschriebenen Bereichen kann es sich im Rahmen der Erfindung z.B. um den mittleren Bereich e des Reflektors 5 handeln. Lichtdurchlässige Bereiche f im Reflektor 5 können auch zu beiden Seiten des vorbeschriebenen Bereiches e angeordnet sein. Vorzugsweise ist der Reflektor 5 auf seiner gesamten Fläche lichtdurchlässig oder lichtteildurchlässig. Bei der vorliegenden Ausgestaltung weist der Reflektor 5 auf seiner gesamten Fläche Löcher 53 auf, wobei seine übrige Unterfläche lichtreflektierend ausgebildet, insbesondere beschichtet ist, so daß ein Teil der Lichtstrahlen zur Abdeckung 7 hin reflektiert wird und ein Teil der Lichtstrahlen in das Gehäusebasisteil 6 strahlt. Vorzugsweise ist ein solcher Reflektor 5 aus einem mit Löchern 53 vorgefertigtem Lochblech hergestellt. Figur 4 zeigt aus Vereinfachungsgründen nur einen Teilbereich des auf seiner gesamten Breite und Länge Löcher 53 aufweisenden Reflektors 5.Within the scope of the invention, the above-described area or areas can be, for example, the central area e of the reflector 5. Translucent areas f in the reflector 5 can also be arranged on both sides of the above-described area e. The reflector 5 is preferably translucent or partially translucent over its entire surface. In the present embodiment, the reflector 5 has holes 53 over its entire surface, its remaining lower surface being designed to be light-reflecting, in particular coated, so that some of the light rays are reflected toward the cover 7 and some of the light rays radiate into the housing base part 6. Such a reflector 5 is preferably produced from a perforated plate prefabricated with holes 53. For reasons of simplification, FIG. 4 shows only a partial area of the reflector 5, which has holes 53 over its entire width and length.

Außerdem bestehen wenigstens die Gehäuseaußenwände des Gehäusebasisteils 6, vorzugsweise das Gehäusebasisteil 6 insgesamt, aus lichtdurchlässigem oder durchsichtigem Material wie Glas oder insbesondere Kunststoff, vorzugsweise unzerbrechlichem Kunststoff wie Polycarbonat. Dabei ist es besonders vorteilhaft, das Gehäusebasisteil 6 aus dem gleichen Material herzustellen, aus dem die Abdeckung 7 besteht. Dies ist nicht nur herstellungstechnisch einfacher, sondern damit wird auch eine höhere bzw. sichere Abdichtung erreicht, weil das Gehäusebasisteil 6 und die Abdeckung 7 den gleichen Wärme-Ausdehnungskoeffizienten haben und deshalb bei Erwärmung im Betrieb der Leuchte 1 Verzug, Verspannungen und Verschiebungen vermieden sind.In addition, at least the housing outer walls of the housing base part 6, preferably the housing base part 6 as a whole, consist of translucent or transparent material such as glass or in particular plastic, preferably unbreakable plastic such as polycarbonate. It is particularly advantageous to produce the housing base part 6 from the same material from which the cover 7 is made. This is not only simpler in terms of production technology, but also a higher or more reliable seal is achieved because the housing base part 6 and the cover 7 have the same coefficient of thermal expansion and therefore warping, tensioning and displacements are avoided when the lamp 1 is heated during operation.

Bei der vorbeschriebenen Leuchte 1 wird ein Teil der Lichtstrahlen, nämlich die in das Gehäusebasisteil 6 strahlenden Lichtstrahlen zu der Seite der Leuchte 1 hin gestrahlt, auf der sich das Gehäusebasisteil 6 befindet, und zwar gegen das die Leuchte 1 tragende Bauteil, in der Regel eine Decke oder eine Wand. Auf diese Weise erhält man eine Leuchte, die sowohl direkt als auch indirekt leuchtet und den die Leuchte 1 tragenden Basisbereich beleuchtet. Hierdurch wird der vorhandene Raum besser beleuchtet, und er erscheint heller.In the luminaire 1 described above, part of the light rays, namely the light rays radiating into the housing base part 6, is radiated toward the side of the luminaire 1 on which the housing base part 6 is located, specifically against the component carrying the luminaire 1, as a rule one Ceiling or wall. In this way, a luminaire is obtained which shines both directly and indirectly and illuminates the base area carrying the luminaire 1. This will illuminate the existing space better and make it appear brighter.

Die erfindungsgemäße Leuchte 1 eignet sich vorzüglich für eine Feuchtraumleuchte und somit für feuchte, staubige und auch untergeordnete Räume, da insbesondere solche Räume einer besseren Ausleuchtung bedürfen und zwar nicht nur im die Leuchte tragenden Decken- oder Wandbereich, sondern auch insgesamt.The luminaire 1 according to the invention is particularly suitable for a damp room luminaire and thus for damp, dusty and also subordinate rooms, since such rooms in particular need better illumination, not only in the ceiling or wall area carrying the luminaire, but also overall.

Das Ausführungsbeispiel gemäß Figur 5, bei dem gleiche oder vergleichbare Teile mit gleichen Bezugszeichen versehen sind, unterscheidet sich vom vorbeschriebenen Ausführungsbeispiel im wesentlichen nur dadurch, daß die Leuchte breiter bemessen ist und mehrere Lampen bzw. Leuchtstoffröhren 4, vorzugsweise zwei Stück, mit zugehörigen Fassungen (3) nebeneinander angeordnet sind. Dabei können die beiden kreisbogenförmig gewölbten Seitenbereiche der Abdeckung 7 im mittleren Bereich der Leuchte durch einen sekantialen Bodenabschnitt 17a miteinander verbunden sein.The exemplary embodiment according to FIG. 5, in which the same or comparable parts are provided with the same reference numerals, differs from the exemplary embodiment described above essentially only in that the lamp is dimensioned wider and several lamps or fluorescent tubes 4, preferably two, with associated sockets ( 3) are arranged side by side. The two side areas of the cover 7 which are curved in the shape of a circular arc can be connected to one another in the central area of the lamp by a secant bottom section 17a.
