Abstract

The convex housing (1) of the exterior light fixture is covered at its open underside by a detachably mounted transparent cover (2), the required kerf being in the horizontal plane. In order to form the kerf in a manner proof against spray and without an additional seal of special material, there is arranged on the housing (1) in the region of the kerf a circumferential rim formation (1a) which is inclined obliquely outwards, serves as the actual sealing surface (1b), and has an annular bead (1c), which is joined towards the outer rim and arches upwards, and which is joined by a free-standing rim (1d), which is directed downwards and engages over the rim (2a) of the cover (2). For its part, the cover (2) is provided circumferentially with a flange (2a) which is matched to the inclination of the sealing surface (1b) and bears directly against it. However, below the annular bead (1c) the flange (2a) is arranged in a freely standing manner and reaches up to a small gap (3a), also provided for tolerance compensation, virtually as far as the rim (1d). This results in formation below the annular bead (1c) of a prechamber (3) for spray that has gained access, which can settle therein and flow off once again through the gap (3a). In the case of a circular rim formation of the housing (1) and a round cover (2), the latter is preferably held by a plurality of bow-shaped wire springs (4) arranged in the housing. <IMAGE>

Description

Die Erfindung betrifft eine Außenleuchte mit einem Lichtquelle und weitere Einbauteile aufnehmenden haubenförmigen Gehäuse, welches an seiner offenen Unterseite mit einer lichtdurchlässigen Wanne abgedeckt ist, die ihrerseits am profilierten Rand des Gehäuses an einer etwa in horizontaler Ebene befindlichen, spritzwasserdicht ausgebildeten Trennfuge abnehmbar gehalten ist.The invention relates to an outdoor lamp with a light source and other built-in housing-shaped housing, which is covered on its open underside with a translucent trough, which in turn is held detachably on the profiled edge of the housing at an approximately horizontal plane, splash-proof formed parting line.

Derartige Außenleuchten sind in vielfältigen Ausführungen bekannt. Bei den meisten ist im Randbereich der Gehäuseöffnung eine separate Dichtung aus Gummi oder Filz eingelegt oder auch eingeklebt. Eine beispielsweise über Hebelverschlüsse am Gehäuse gehaltene Wanne liegt dadurch mit ihrem Rand so fest an der Dichtung an, daß auch bei Oberflächenunebenheiten in der Trennfuge ein ausreichender Schutz gegen Feuchtigkeit und Staub gewährleistet ist. Solche Dichtungen sind jedoch auch bei guter Qualität nur bedingt alterungsbeständig. Meist läßt die Dichtwirkung nach einigen Jahren durch mehrfaches Abnehmen der Wanne aufgrund der von Zeit zu Zeit erforderlichen Lampenwechsel und Wartungsarbeiten erheblich nach. Außerdem sind für die separate Dichtung und ihren Einbau zusätzliche Kosten erforderlich.Such outdoor lights are known in a variety of designs. Most have a separate rubber or felt seal inserted or glued into the edge area of the housing opening. A trough, for example, held on the housing by means of lever locks, rests with its edge so firmly against the seal that sufficient protection against moisture and dust is ensured even in the event of uneven surfaces in the joint. However, even with good quality, such seals are only partially resistant to aging. Most of the time, the sealing effect diminishes considerably after several years by repeatedly removing the tub due to the lamp replacement and maintenance work required from time to time. In addition, additional costs are required for the separate seal and its installation.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Außenleuchte zwischen dem zumeist metallischen oder aus Kunststoff bestehenden Gehäuse und der abnehmbaren transparenten Wanne, insbesondere bei etwa horizontal angeordneter Trennfuge, eine gegen Spritzwasser ausreichend wirksame Dichtungseinrichtung zu schaffen, bei der eine zusätzliche Dichtung aus einem speziellen Material nicht erforderlich ist.The invention has for its object to provide an adequately effective sealing device against splashing water in an external light between the mostly metallic or plastic housing and the removable transparent trough, in particular with a horizontally arranged joint, in which an additional seal made of a special material is not required.

Diese Aufgabe wird durch eine Außenleuchte mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. Weiterbildungen und vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by an outdoor lamp with the characterizing features of patent claim 1. Further developments and advantageous refinements of the invention are specified in the subclaims.

Anhand der in der Zeichnung dargestellten einzigen Figur mit einem Teilquerschnitt einer Außenleuchte wird die Erfindung nachstehend näher erläutert.The invention is explained in more detail below on the basis of the single figure shown in the drawing, with a partial cross section of an outdoor lamp.

Die Außenleuchte hat ein vorzugsweise rotationssymmetrisches metallisches Gehäuse (1) und eine dieses an seiner offenen Unterseite abdeckende lichtdurchlässige Wanne (2), die jeweils schematisch nur mit einer Randzone im Querschnitt gezeigt sind. Das haubenförmig ausgebildete, an der Oberseite geschlossene Gehäuse nimmt in seinem Innern eine oder mehrere nicht gezeigte Lichtquellen, sowie elektrische und mechanisch erforderliche Einbauteile auf. An seiner offenen Unterseite ist das Gehäuse mit einer umlaufenden profilierten Randausbildung (1a) versehen, welche als wesentliche Elemente eine um etwa 20° nach außen geneigte Dichtfläche (1b) mit sich daran nach außen hin anschließender aufsteigend gewölbter Ringwulst (1c) aufweist. Erst an diese Ringwulst schließt sich ein abwärts gerichteter freistehender Rand (1d) des Gehäuses an, der seinerseits die vorzugsweise aus einem transparenten Kunststoff tief gezogene Wanne (2) an ihrem als Flansch (2a) ausgebildeten Außenrand übergreift. Der Flansch (2a) hat die gleiche Neigung wie die Dichtfläche (1b) am Gehäuserand, so daß die Wanne auch bei einer leichten Oberflächenstruktur ihres Ausgangsmaterials unmittelbar an der Dichtfläche anliegt.The exterior light has a preferably rotationally symmetrical metallic housing (1) and a translucent trough (2) covering this on its open underside, each of which is shown schematically in cross section with only one edge zone. The inside of the hood-shaped housing, closed at the top, accommodates one or more light sources, not shown, as well as electrical and mechanically required built-in parts. On its open underside, the housing is provided with a circumferential, profiled edge formation (1a) which, as essential elements, has a sealing surface (1b) which is inclined outward by approximately 20 ° with an annular bulge (1c) which rises outwards thereafter. Only this annular bead is followed by a downward-facing free-standing edge (1d) of the housing, which in turn overlaps the tub (2), which is preferably deep-drawn from a transparent plastic, on its outer edge designed as a flange (2a). The flange (2a) has the same inclination as the sealing surface (1b) on the edge of the housing, so that the trough is in direct contact with the sealing surface even with a light surface structure of its starting material.

Der im Anschluß an die Dichtfläche (1b) unter der Ringwulst (1c) frei vorstehende Flansch (2a) ragt mit seiner Außenkontur (2a′) nahezu bis an den Rand (1d) des Gehäuses und bildet zusammen mit der Ringwulst eine Vorkammer (3). Diese ist umlaufend in der Trennfuge zwischen Gehäuse und Wanne vorhanden und lediglich über einen schmalen Spalt (3a) nach außen hin offen. Der Spalt dient zum Ausgleich von Toleranzen und unterschiedlichen Wärmedehnungen zwischen Kunststoffwanne einerseits und Blechgehäuse andererseits. Entsprechende Gleitbewegungen zwischen dem Flansch (2a) und Dichtfläche (1b) sind daher ungehindert möglich. Die Vorkammer (3) verengt sich zur Dichtfläche hin und hat in praktischen Ausführungsbeispielen Querschnittswerte von etwa 20 bis zu 50 mm². Auf die Wirkung der Vorkammer wird noch näher einzugehen sein.The flange (2a) which projects freely under the annular bead (1c) following the sealing surface (1b) projects with its outer contour (2a ′) almost to the edge (1d) of the housing and forms a prechamber (3) together with the ring bead. This is all around in the parting line between the housing and the tub and is only open to the outside via a narrow gap (3a). The gap serves to compensate for tolerances and different thermal expansions between the plastic tub on the one hand and the sheet metal housing on the other. Corresponding sliding movements between the flange (2a) and sealing surface (1b) are therefore possible without hindrance. The prechamber (3) narrows towards the sealing surface and has cross-sectional values of approximately 20 to 50 mm² in practical exemplary embodiments. The effect of the antechamber will be discussed in more detail.

Während die vorbeschriebene Randausbildung bei Außenleuchten mit beliebiger Grundform der Lichtaustrittsfläche eingesetzt werden kann, ist die im folgenden beschriebene Halterung der Wanne am Gehäuse für Leuchten mit zumindest annähernd kreisförmiger Lichtaustrittsfläche vorgesehen. Hierzu sind im Bereich der Randausbildung (1a) bügelförmige Drahtfedern (4) angeordnet, die im Innern des Gehäuses verdeckt montiert sind. Vorzugsweise sind drei oder vier Drahtfedern am Umfang der Leuchte gleichmäßig verteilt angeordnet. Jede Drahtfeder greift mit ihren beiden mehrfach gewinkelten Schenkeln (4a) von unten her durch eine Zweierlochgruppe (1e) im Bereich der Ringwulst (1c) und verhakt sich mit beiden freien Enden (4a′) hinter herausgestellten Nasen (1f). Diese sind an der Randausbildung (1a) noch vor dem Bereich der umlaufenden Dichtfläche (1b) nach oben hin ausgestellt und ebenso wie die Löcher (1e) an den Drahtdurchmesser der Federschenkel angepaßt. Während die elastisch hinter den Nasen (1f) verhakten freien Enden (4a′) die Drahtfeder in vertikaler Richtung zentrieren, bestimmt die Lochgruppe (1e) die Lage in der Horizontalen. Jede Drahtfeder ist somit zuverlässig gehalten und verfügt ihrerseits über einen Bügelteil (4b) mit hoher Wölbung zwischen den Schenkeln (4a), so daß lange Federwege mit gleichmäßiger Federkraft gegeben sind.While the above-described edge formation can be used in the case of outdoor lights with any basic shape of the light exit surface, the mounting of the trough on the housing described below is provided for lights with at least approximately circular light exit surface. For this purpose, bow-shaped wire springs (4) are arranged in the area of the edge formation (1a) and are mounted concealed in the interior of the housing. Preferably three or four wire springs are arranged evenly distributed on the circumference of the lamp. Each wire spring grips with its two multi-angled legs (4a) from below through a two-hole group (1e) in the area of the ring bead (1c) and hooks with both free ends (4a ') behind protruding lugs (1f). These are raised on the edge formation (1a) before the area of the circumferential sealing surface (1b) and, like the holes (1e), are adapted to the wire diameter of the spring legs. While the free ends (4a ′), which are elastically hooked behind the lugs (1f), center the wire spring in the vertical direction, the hole group (1e) determines the position in the horizontal. Each wire spring is thus held reliably and in turn has a bracket part (4b) with a high curvature between the legs (4a), so that long spring travel is given with a uniform spring force.

Entsprechend der Anzahl der Drahtfedern und ihrer Verteilung im Gehäuse ist die Wanne (2) im Bereich des umlaufenden Flansches (2a) mit Teilausschnitten (2b) versehen. Diese sind jedoch nur partiell unterhalb der Ringwulst (1c) im Flansch angeordnet und in ihrer Länge an den Abstand der Federschenkel (4a) angepaßt. Dadurch ist es möglich, die Wanne von unten her mit den Teilausschnitten (2b) am Bügelteil (4b) der Drahtfedern vorbei bis an die Dichtfläche (1b) des Gehäuses einzusetzen. Bei einer anschließenden tangentialen Drehung der Wanne schiebt sich der Flansch (2a) mit seiner Unterseite über den gewölbten elastischen Bügelteil (4b) der Drahtfeder. Die Wanne ist somit sicher gehalten und liegt mit dem Flansch eng auf der Dichtfläche (1b) an. Der erforderliche tangentiale Verschiebeweg ist mittels eines nicht gezeigten Anschlags im Bereich eines Teilausschnittes vorbestimmt und entsprechend begrenzt.Depending on the number of wire springs and their distribution in the housing, the trough (2) is provided with partial cutouts (2b) in the area of the circumferential flange (2a). However, these are only partially arranged below the annular bead (1c) in the flange and their length is adapted to the distance between the spring legs (4a). This makes it possible to insert the trough from below with the partial cutouts (2b) past the bracket part (4b) of the wire springs up to the sealing surface (1b) of the housing. During a subsequent tangential rotation of the trough, the flange (2a) pushes with its underside over the curved elastic bracket part (4b) of the wire spring. The trough is thus held securely and lies flush with the flange on the sealing surface (1b). The required tangential displacement path is predetermined by means of a stop (not shown) in the area of a partial section and is limited accordingly.

Unabhängig von der Befestigung der Wanne ist die Wirkung der eingangs beschriebenen Randausbildung zwischen Gehäuse und Wanne gegen eindringende Feuchtigkeit, insbesondere Spritzwasser. Sollte dieses beispielsweise bei Schlagregen auftreten, so kann es zwar durch den Spalt (3a) in die Vorkammer (3) eintreten, die dem Spritzwasser jedoch den Druck wegnimmt und ihm eine ausgleichende Fließbewegung innerhalb der Ringwulst ermöglicht. Von hier kann zwar Feuchtigkeit in die oberflächenrauhe Trennfuge zwischen Wannenflansch und Dichtfläche (1b) aufgrund von Kapillarwirkung aufsteigen, ein Abfließen in die Wanne erfolgt jedoch nicht. Die Feuchtigkeit in der etwa um 20° nach außen geneigten Trennfuge fließt vielmehr wieder nach außen in die Ringwulst ab und entspannt sich dort, oder fließt durch den vom freien Rand (1d) des Gehäuses geschützten Spalt (3a) an windabgekehrter Seite aus der Vorkammer ab.Regardless of the attachment of the tub, the effect of the edge formation between the housing and tub described at the outset is against the ingress of moisture, in particular splash water. Should this occur, for example, during driving rain, it can indeed enter the prechamber (3) through the gap (3a), but this takes the pressure away from the spray water and enables it to have a compensating flow movement within the ring bead. From here, moisture can rise into the rough surface joint between the tub flange and sealing surface (1b) due to capillary action, a drain into the tub however, does not take place. Rather, the moisture in the parting line, which is inclined outwards by about 20 °, flows outwards again into the annular bead and relaxes there, or flows out of the prechamber on the side facing away from the wind through the gap (3a) protected by the free edge (1d) of the housing .

Die Dichtwirkung der erfindungsgemäßen Randausbildung wird nicht nur bei Außenleuchten mit horizontaler Gebrauchslage erreicht, sondern auch, wenn die Lichtaustrittsfläche und damit die Trennfuge gegenüber der horizontalen Ebene bis etwa 10° geneigt angeordnet ist. Um Schwitzwasserbildung zu vermeiden, empfiehlt es sich in jedem Fall, an der tiefsten Stelle der Wanne eine Zwangsentlüftung mittels feiner Öffnungen vorzusehen.The sealing effect of the edge formation according to the invention is achieved not only in the case of outdoor lamps with a horizontal position of use, but also when the light exit surface and thus the parting line are arranged inclined up to approximately 10 ° with respect to the horizontal plane. In order to avoid condensation, it is always advisable to provide forced ventilation at the deepest point of the tub using fine openings.
