In den Figuren 1 bis 3 ist die Feuchtraumleuchte allgemein mit 1 bezeichnet. Sie besteht im wesentlichen aus einem Gehäuse 2 mit einer verschiedene Installationseinrichtungen tragenden Geräteschiene 3 sowie einem Reflektor 4 und einer lösbar am Gehäuse 2 befestigten, transparenten Leuchtenwanne 5.The moisture-proof luminaire is generally designated 1 in FIGS. 1 to 3. It essentially consists of a housing 2 with a device rail 3 carrying various installation devices, as well as a reflector 4 and a transparent lamp tray 5 detachably attached to the housing 2.

Bei dem Gehäuse 2 handelt es sich um einen einstückigen, trogförmig gespritzten Kunststoffkörper, welcher am Gehäuseboden 6 mit wenigstens zwei nach außen vorstehenden Befestigungsaugen 7 für die Leuchte und außer einer eingezogenen schrägen Kabeleinführung 8 innen, mit zwei Tiefzügen 9 für die Befestigung der Geräteschiene 3 versehen ist. Außerdem weist das Gehäuse 2 einen umlaufenden Stehrand 10 und eine gegenüber diesem tiefer liegende Nut 11 auf, die eine vorzugsweise aus einer Rundschnur gebildete Dichtung 12 aufnimmt (Fig. 3 und 4).The housing 2 is a one-piece, trough-shaped injection molded plastic body, which is provided on the housing base 6 with at least two outwardly projecting fastening eyes 7 for the lamp and, apart from a retracted oblique cable entry 8 on the inside, with two deep-drawn means 9 for fastening the device rail 3 is. In addition, the housing 2 has a circumferential standing edge 10 and a groove 11 lying deeper than this, which receives a seal 12 which is preferably formed from a round cord (FIGS. 3 and 4).

Die Geräteschiene 3 besteht aus einem in der Seitenansicht im wesentlichen L-förmig aussehenden Blechstanzbiegeteil U-förmigen Querschnitts. Wie insbesondere die Fig. 1 und 2 zeigen, ist ihr längerer Schenkel 13 mit einem Vorschaltgerät 14 sowie einer Anschlußklemme 15 und ihr um 90° abgewinkelter kürzerer Schenkel 16 mit einer Kabeltülle 17 sowie einer Lampenfassung 18 bestückt. Die Teile werden nach ihrer vorzugsweise durch Aufstecken erfolgenden Befestigung verdrahtet, wobei das Vorschaltgerät 14 nur an einem Befestigungsende in eine entsprechende Ausbildung der Geräteschiene 3 gesteckt ist, während das andere Befestigungsende mittels einer in einen Durchzug der Geräteschiene 3 eingedrehten Blechschraube fixiert ist. Der Aktivteil des Vorschaltgerätes 14 ist dabei durch die seitlichen Abkantungen des längeren Schenkels 13 der Geräteschiene 3 abgeschirmt. Das heißt, daß die seitlichen Abkantungen der Bauhöhe des Vorschaltgerätes 14 entsprechen, wodurch letzteres eine vollständig im U-Profil der Geräteschiene 3 versenkte Lage einnimmt. Der kürzere Geräteschienen- Schenkel 16 weist nur relativ schmale, der mechanischen Versteifung dienende seitliche Abkantungen auf, die vorzugsweise auf der den längeren Schenkel 13 aufweisenden Seite der Geräteschiene 3 angeordnet sind. In dem in Befestigungslage der Geräteschiene 3 über den Stehrand 10 des Gehäuses 2 hinausragenden Endbereich des kürzeren Schenkels 16 ist eine spezielle Ausnehmung für die Rastbefestigung der Lampenfassung 18 enthalten, welche vom längeren Schenkel 13 her gesehen hinter dem kürzeren Schenkel 16 im Abdeckbereich der Leuchtenwanne 5 angeordnet ist. Die Lampenfassung 18 ist für G 23 Leuchtmittel ausgebildet, bei denen es sich um einseitig gesockelte, U-förmige Leuchtstofflampen handelt. Wie in Fig. 1 schematisch dargestellt ist, erstreckt sich eine in die Fassung gesteckte Leuchtstofflampe 19 in parallelem Abstand zum längeren Schenkel 13 der Geräteschiene 3, welcher jedoch kürzer bemessen ist als die Gehäuselänge.The device rail 3 consists of a sheet-metal stamped bent part which has a U-shaped cross section and looks essentially L-shaped in side view. As shown in FIGS. 1 and 2 in particular, its longer leg 13 is equipped with a ballast 14 and a connecting terminal 15 and its shorter leg 16 angled by 90 ° with a cable grommet 17 and a lamp holder 18. The parts are wired after they are preferably attached by being fastened, the ballast 14 being plugged into a corresponding configuration of the device rail 3 at only one fastening end, while the other fastening end is fixed by means of a self-tapping screw screwed into a passage of the device rail 3. The active part of the ballast 14 is shielded by the lateral folds of the longer leg 13 of the device rail 3. This means that the lateral folds correspond to the overall height of the ballast 14, as a result of which the latter assumes a position that is completely recessed in the U-profile of the device rail 3. The shorter device rail leg 16 has only relatively narrow, mechanical stiffening lateral folds, which are preferably arranged on the side of the device rail 3 having the longer leg 13. In the fastening area of the device rail 3, which projects beyond the standing edge 10 of the housing 2, the end portion of the shorter leg 16 contains a special recess for the snap fastening of the lamp holder 18, which, viewed from the longer leg 13, is arranged behind the shorter leg 16 in the covering area of the lamp trough 5 is. The lamp holder 18 is designed for G 23 lamps, which are U-shaped fluorescent lamps with a base on one side. As shown schematically in FIG. 1, a fluorescent lamp 19 inserted into the socket extends at a parallel distance from the longer leg 13 of the device rail 3, which is, however, dimensioned shorter than the length of the housing.

Die außerhalb des Leuchtengehäuses komplett vormontierte Geräteschiene 3 wird zur Befestigung mit dem längeren Schenkel 13 und mit Abstand zum Gehäuseboden 6 so auf die Tiefzüge 9 des Gehäuses 2 gelegt, daß ihre Abkantungen zur offenen Gehäuseseite gerichtet sind. An schließend wird mit einem einfachen Werkzeug je eine Sicherungsscheibe 20 auf einen aus jedem Tiefzug 9 hervorstehenden Zapfen 21 gedrückt, wobei sich die Innenverzahnung der Sicherungsscheibe 20 am Zapfen 21 verstemmt. In dieser Befestigungslage erstreckt sich die Lampenfassung 18 bei montierter Leuchtenwanne 5 zwischen dem kürzeren Schenkel 16 der Geräteschiene 3 und dem nächstliegenden Wannenende.The completely pre-assembled device rail 3 outside the luminaire housing is placed for fastening with the longer leg 13 and at a distance from the housing base 6 on the deep-drawn parts 9 of the housing 2 such that their folds are directed towards the open housing side. At closing, a locking washer 20 is pressed onto a pin 21 protruding from each deep-drawing 9 with a simple tool, the internal toothing of the locking washer 20 being caulked on the pin 21. In this fastening position, the lamp socket 18 extends with the lamp trough 5 installed between the shorter leg 16 of the device rail 3 and the nearest trough end.

Wie die Fig. 3 zeigt, weist der vorzugsweise aus Blech gestanzte Reflektor 4 in Einbaulage an seinen Längsseiten je eine zum Gehäuse 2 gerichtete Abbiegung 22 auf, die mit ihrer unteren Kante auf den freien Enden von wenigstens zwei Stützrippen 23 liegt. Die Stützrippen 23 sind mit Abstand zueinander so an den Innenseiten des Gehäuses 2 angeformt, daß sie sich quer zu dessen Längsachse erstrecken und in etwa auf der Höhe des Stehrandes 10 enden. Ebenfalls ungefähr auf Stehrandhöhe sind im kürzeren Schenkel 16 der Geräteschiene 3 mit Abstand nebeneinander zwei V-förmige Schlitze 24 vorgesehen. In diese wird der Reflektor 4 bei der Montage mit zwei an einem Ende entsprechend vorstehenden, ebenen Lappen 25 eingesteckt (Fig. 6), während das andere Reflektorende an einen säulenförmigen Tiefzug des Gehäuses 2 geschraubt wird (nicht dargestellt). Weil die Schlitze 24 in der Geräteschiene 3, das freie Ende des säulenförmigen Durchzuges im Gehäuse 2 und die Auflageflächen seiner Stützrippen 23 annähernd in einer Ebene liegen, erhält der Reflektor 4 eine um die Leuchtenlängsachse verlaufende Wölbung, die in Abhängigkeit vom Maß der längsseitigen Abbiegungen 22 und je nach gewünschter Lichtreflexion eine schwache bis starke Krümmung aufweist oder bei fehlenden Abbiegungen 22 gänzlich entfällt.As FIG. 3 shows, the reflector 4, which is preferably stamped out of sheet metal, has in the installed position on its longitudinal sides each a bend 22 directed towards the housing 2, which has its lower edge the free ends of at least two support ribs 23. The support ribs 23 are formed at a distance from one another on the inner sides of the housing 2 in such a way that they extend transversely to its longitudinal axis and end approximately at the height of the standing edge 10. Also approximately at the level of the standing edge, two V-shaped slots 24 are provided next to one another in the shorter leg 16 of the device rail 3 at a distance. In the latter, the reflector 4 is inserted during assembly with two flat tabs 25 projecting at one end (FIG. 6), while the other end of the reflector is screwed to a column-shaped deep drawing of the housing 2 (not shown). Because the slots 24 in the device rail 3, the free end of the column-shaped passage in the housing 2 and the contact surfaces of its support ribs 23 are approximately in one plane, the reflector 4 is given a curvature extending around the longitudinal axis of the lamp, which, depending on the dimension of the longitudinal bends 22 and, depending on the desired light reflection, has a slight to strong curvature or is completely eliminated if there are no turns 22.

Der fertig montierte Reflektor 4 ist in der Feuchtraumleuchte 1 zwischen Vorschaltgerät 14 und Leuchtstofflampe 19 angeordnet, wo er sich zwischen dem kürzeren Schenkel 16 der Geräteschiene 3 bis kurz vor das Ende der Leuchtenwanne 5 erstreckt. Über die sich bei der Montage in den V-förmigen Schlitzen 24 verstemmenden Blechlappen 25 wird der Reflektor 4 auch elektrisch mit der Geräteschiene 3 verbunden, die bei installierter Leuchte ihrerseits über die Anschlußklemme 15 mit dem Schutzleiter verbunden ist.The fully assembled reflector 4 is arranged in the moisture-proof luminaire 1 between the ballast 14 and the fluorescent lamp 19, where it extends between the shorter leg 16 of the device rail 3 to just before the end of the lamp trough 5. The reflector 4 is also electrically connected to the device rail 3 via the sheet metal lugs 25 which are caulked in the V-shaped slots 24 and, in turn, is connected to the protective conductor via the connecting terminal 15 when the lamp is installed.

In Fig. 4 ist die Ausführung der Rastverbindung zwischen Gehäuse 2 und Leuchtenwanne 5 dargestellt. Letztere besteht aus einem transparenten Kunststoffkörper mit einem umlaufenden Stehrand 26 und einer in parallelem Abstand dazu ebenfalls umlaufenden Abschlußleiste 27. Diese ist auf der in Einbaulage sichtbaren Unterseite aus der Wannenwölbung heraus nach außen gerundet, während ihre Oberseite eine ebene Fläche bildet. Auf jeder Längsseite weist die Abschlußleiste 27 wenigstens zwei bis an die ursprüngliche Wandungsdicke reichende Ausnehmungen 28 auf, über denen mit Abstand und jeweils mittig eine nach außen gerichtete Rastnase 29 angeordnet ist. Die horizontal verlaufende Unterseite der Rastnase 29 bildet eine Rastschulter und die Rastnasenoberseite eine Auflaufschräge. Durch Andrücken der Leuchtenwanne 5 gegen den Stehrand 10 des Gehäuses 2 schnappen die Rastnasen 29 in entsprechende Durchbrüche 30 dieses Stehrandes 10 ein. Hierbei werden Gehäuse 2 und Leuchtenwanne aneinander befestigt und zugleich das freie Ende des Stehrandes 26 der Leuchtenwanne 5 in die Dichtung 12 des Gehäuses gedrückt. Um ein leichtes Einrasten zu gewährleisten, ist die untere Kante des Gehäuse-Stehrandes 10 in den Bereichen unterhalb der Durchbrüche 30 innen abgeschrägt, so daß sich der Stehrand 10 ohne großen Kraftaufwand elastisch auslenken läßt.4 shows the design of the snap-in connection between the housing 2 and the lamp trough 5. The latter consists of a transparent plastic body with an encircling standing edge 26 and an end strip 27 which also encircles at a parallel distance from it. This is rounded on the underside, visible in the installed position, out of the tub arch, while its top side forms a flat surface. On each long side, the end strip 27 has at least two recesses 28 reaching to the original wall thickness, above which a detent 29 is arranged at a distance and in the middle. The horizontally running underside of the latching lug 29 forms a latching shoulder and the latching lug upper side forms a run-up slope. By pressing the lamp trough 5 against the standing edge 10 of the housing 2, the locking lugs 29 snap into corresponding openings 30 in this standing edge 10. In this case, housing 2 and luminaire trough are fastened to one another and at the same time the free end of the standing edge 26 of the luminaire trough 5 is pressed into the seal 12 of the housing. In order to ensure easy latching, the lower edge of the housing upright edge 10 is chamfered on the inside in the areas below the openings 30, so that the upright edge 10 can be deflected elastically without great effort.

Die ebene Oberseite der Abschlußleiste 27 ist breiter als der Stehrand 10 des Gehäuses 2; daher wird zwischen diesem und dem Stehrand 26 der Leuchtenwanne 5 im Bereich jeder Ausnehmung 28 eine schlitzförmige Öffnung 31 gebildet (Fig. 4), in die ein einfaches Werkzeug 32, wie z.B. ein Schraubendreher einsteckbar ist. Damit läßt sich der Gehäuserand nach außen drücken, wodurch die Verrastung aufgehoben wird und die Leuchtenwanne 5 vom Gehäuse 2 abgenommen werden kann.The flat top of the end strip 27 is wider than the standing edge 10 of the housing 2; therefore a slot-shaped opening 31 is formed between this and the standing edge 26 of the lamp trough 5 in the region of each recess 28 (FIG. 4), into which a simple tool 32, such as e.g. a screwdriver can be inserted. This allows the edge of the housing to be pressed outwards, as a result of which the latching is released and the lamp trough 5 can be removed from the housing 2.

Bei der Feuchtraumleuchte 1 wird der von der Leuchtstofflampe 19 nicht erhellte Leuchtenteil mit der Lampenfassung 18, insbesondere im Betriebszustand als ein von außen sichtbarer Dunkelraum wahrgenommen. Um diesen Eindruck zu vermeiden, ist die sonst durchgehend glatte Leuchtenwanne 5 bei dem in Fig. 1 dargestellten Ausführungsbeispiel im Bereich der Lampenfassung 18 etwas nach innen eingezogen und durch eine aufgerastete, aus lichtundurchlässigem Werkstoff bestehende Kappe 33 abgedeckt.In the wet room luminaire 1, the luminaire part with the lamp holder 18 which is not illuminated by the fluorescent lamp 19 is perceived as a dark room which is visible from the outside, in particular in the operating state. In order to avoid this impression, the otherwise continuously smooth lamp trough 5 in the exemplary embodiment shown in FIG. 1 is drawn in somewhat in the area of the lamp holder 18 and covered by a snap-on cap 33 made of opaque material.

Die Kappe 33 entspricht in der äußeren Form dem anderen Wannenende und sie weist einen dem Querschnitt der Abschlußleiste 27 angepaßten Kappenrand 34 auf (Fig. 5). Unterhalb des Kappenrandes 34 ist vorzugsweise auf den beiden sich gegenüberstehenden Innenseiten je eine Rastnase 35 angeordnet, die beim Aufrasten der Kappe 33 auf die Leuchtenwanne 5 in entsprechend eingeformte Nischen 36 der Leuchtenwanne einschnappen. In dieser Befestigungslage schließt die Außenfläche der Kappe 33 mit der noch sichtbaren Außenfläche der Leuchtenwanne 5 glatt ab. Zwischen der abgedeckten Außenfläche der Leuchtenwanne 5 und der Kappeninnenseite wird jedoch durch mehrere in Leuchtenlängsrichtung innen an die Kappe 33 angeformte Rippen geringer Höhe ein Luftspalt gebildet, so daß eventuell eindringendes Wasser nicht in der Kappe stehen bleibt, sondern ablaufen kann.The outer shape of the cap 33 corresponds to the other end of the tub and it has a cap edge 34 which is adapted to the cross section of the end strip 27 (FIG. 5). Below the edge 34 of the cap, a latch 35 is preferably arranged on each of the two opposing inner sides, which snap into place when the cap 33 is snapped onto the lamp trough 5 in correspondingly molded-in niches 36 of the lamp trough. In this fastening position, the outer surface of the cap 33 closes off smoothly with the still visible outer surface of the lamp trough 5. Between the covered outer surface of the lamp trough 5 and the inside of the cap, however, an air gap is formed by a plurality of ribs of low height formed on the inside of the cap 33 in the longitudinal direction of the lamp, so that any water that penetrates does not remain in the cap, but can run off.

Bei dem beschriebenen Ausführungsbeispiel wird die Kappe 33 mittels einer lösbaren Rastverbindung an der Leuchtenwanne 5 gehalten. Die hier an beiden Teilen notwendigen Ausbildungen können jedoch entfallen, wenn die Kappe 33 durch Kleben oder Schweißen an der Leuchtenwanne 5 befestigt wird.In the exemplary embodiment described, the cap 33 is held on the lamp trough 5 by means of a releasable latching connection. The training required here on both parts can, however, be omitted if the cap 33 is attached to the lamp trough 5 by gluing or welding.
