Abstract

The light has a tub-shaped base housing to contain fittings, especially to hold fluorescent tubes. It has a cover to close off the open side of the housing, which is transparent at least in the area of the tubes, and is at least partly sunk into a recess (16) in the housing. The cover has a device for fastening it and releasing it from the housing. A sealing strip (11) is arranged in a gap (29) between the outer circumferential surface (28) of the cover and the inner circumferential surface (17) of the recess. The gap is filled or almost completely filled by the strip, and its outer side in the region of the gap aligns or nearly aligns with the outer surfaces of the cover which encloses these and of the housing.

Description

Die Erfindung bezieht sich auf eine Leuchte nach dem Oberbegriff des Anspruches 1, wie sie beispielsweise aus der FR-A-2 658 588 bekannt ist.The invention relates to a lamp according to the preamble of claim 1, as is known for example from FR-A-2 658 588.

Bei einer Leuchte handelt es sich um einen Gegenstand, der nicht nur der Beleuchtung des sie aufnehmenden Raumes dient, sondern die Außenflächen der Leuchte sind zugleich Begrenzungsflächen für den sie aufnehmenden Raum. Dies gilt für eine Anordnung der Leuchte sowohl in der Einbauversion als auch in der Auf- oder Anbauversion und auch bei einer herabhängenden Anordnung der Leuchte. Deshalb können Fugen oder Spalte im Gehäuse Schmutzquellen bilden, wenn sich in den Fugen oder Spalten Schmutz oder Staub ansammelt, was in einem Arbeitsraum kaum zu vermeiden ist. Außerdem können diese Schmutzstellen Bakterienherde bilden, die den Raum beeinträchtigen. Dies gilt insbesondere für einen sogenannten Reinraum, in dem eine Verschmutzung oder Verseuchung durch Bakterien oder dergleichen unerwünscht ist, wie es z. B. bei einem Operations-, Sterilisation-, Isolier- oder auch Produktionsraum für z. B. die Nahrungsmittelindustrie oder Präzisionsgegenstände der Fall ist.A lamp is an object that is not just lighting of the room that receives them, but are the outer surfaces of the lamp at the same time boundary surfaces for the space that receives them. This applies to one Arrangement of the lamp both in the built-in version and in the open or Surface-mounted version and also with a hanging arrangement of the lamp. Therefore joints or gaps in the housing can form sources of dirt if they are in the joints or crevices dirt or dust accumulates, which is hard to find in a work space is to avoid. In addition, these dirt spots can form bacterial foci that the Affect space. This applies in particular to a so-called clean room in which contamination or contamination by bacteria or the like is undesirable is how it z. B. in an operation, sterilization, isolation or Production room for e.g. B. the food industry or precision articles of Case is.

Insbesondere eine Reinraum-Leuchte bedarf oft der Reinigung, was z. B. durch Wischen oder Abspritzen mit Wasser erfolgen kann. Hierbei kann das Reinigungsmittel, wie z. B. Wasser, in die Fugen und Spalten eindringen und als der vorbeschriebene Schmutz- oder Fremdstoff verbleiben, was aus den vorgenannten Gründen unerwünscht ist.In particular, a clean room luminaire often requires cleaning. B. by Wiping or hosing down with water can be done. The detergent, such as B. water, penetrate into the joints and crevices and as the above Dirt or foreign matter remain, which is undesirable for the aforementioned reasons is.

Bei einer bekannten Reinraum-Leuchte, deren Gehäuse aus einem wannenförmigen Basisgehäuseteil und einem daran befestigten Deckel besteht, ist der Deckel in einer Ausnehmung des Gehäuses etwa so weit versenkt angeordnet, daß die Außenfläche des Deckels und die Außenfläche des Gehäuses in etwa miteinander abschließen. Um zu verhindern, daß gasförmige Stoffe oder Wasser bzw. Feuchtigkeit auch kleine Partikel wie Staub aus dem Raum in das Gehäuse oder umgekehrt wandern können, ist zwischen dem Deckel und dem Gehäuse eine Dichtung angeordnet, die an zwei einander gegenüberliegenden, sich parallel zur Ebene des Deckels erstreckenden Dichtungsflächen anliegt. Zwischen der Außenumfangsfläche des Deckels und der ihr gegenüberliegenden Umfangsfläche der Ausnehmung verbleibt bei dieser bekannten Ausgestaltung zwangsläufig ein Spalt, in den Schmutz in der vorbeschriebenen Weise eindringen kann.In a known clean room luminaire whose housing consists of a trough-shaped Base housing part and a lid attached to it, the lid is in one Recess of the housing arranged so far sunk that the outer surface of the Close the lid and the outer surface of the housing approximately together. In order to prevent gaseous substances or water or moisture even small particles how dust can migrate from the room into the housing or vice versa is between the lid and the housing a seal arranged on each other opposite, extending parallel to the plane of the lid Sealing surfaces. Between the outer peripheral surface of the lid and that of you opposite circumferential surface of the recess remains in this known Design inevitably a gap in the dirt in the manner described above can penetrate.

Die zwischen dem Deckel und dem Basisgehäuseteil wirksame Befestigungsvorrichtung wird bei dieser bekannten Leuchte durch einen Schnellverschluß in Form von mehreren, auf dem Umfang des Deckels verteilt angeordneten Spannstiften gebildet, die den Deckel und einen Innenflansch des Basisgehäuseteils in zugehörigen Löchern durchfassen und den Innenflansch mit Verriegelungselementen hintergreifen, die durch eine Vierteldrehung hinter den Innenflansch spannbar und einer Rückdrehung wieder lösbar sind. Die Spannstifte weisen von der Außenseite des Deckels her zugängliche Köpfe mit Werkzeug-Angriffselementen auf, an denen die Spannstifte zwecks einer Drehung angreifbar sind. Auch diese bekannte Ausgestaltung ist mit dem vorbeschriebenen Nachteil behaftet, weil zwischen den Köpfen der Spannstifte und dem Deckel Fugen oder Spalte vorhanden sind, in die eine vorbeschriebene Verschmutzung eindringen kann.The fastening device effective between the cover and the base housing part is in this known lamp by a quick release in the form of several arranged on the circumference of the cover arranged dowel pins that the Cover and an inner flange of the base housing part in associated holes grasp and reach behind the inner flange with locking elements that through a quarter turn behind the inner flange and a back turn again are solvable. The dowel pins are accessible from the outside of the cover Heads with tool engagement elements on which the dowel pins for the purpose of one Rotation are vulnerable. This known embodiment is also with the The disadvantage described above, because between the heads of the dowel pins and the Lid joints or gaps are present in which a pre-described pollution can penetrate.

Hierdurch ist nicht nur die Abdichtung des Spaltes gewährleistet, sondern auch die Ausfüllung des Spaltes durch die Dichtung, so daß kein Spalthohlraum vorhanden ist, in den Schmutz eindringen könnte.In the luminaire according to the invention, the sealing strip is between the outer peripheral surface of the cover and the opposite one Inner circumferential surface of the recess arranged so that on the one hand with the closes the outer end of the gap and the other between the Outer peripheral surface of the lid and the opposite peripheral surface of the Recess is elastically compressed. This is not just the seal of the gap, but also the filling of the gap through the seal, so that there is no gap cavity into which dirt could penetrate.

Es ist von Vorteil, die Außenumfangsfläche des Deckels nach innen konvergent, vorzugsweise konisch auszubilden. Hierdurch wird nicht nur die Montage beim Einsetzen des Deckels erleichtert, weil die konvergente Außenumfangsfläche eine Anlaufschräge bildet, die die Positionierung der Außenumfangsfläche im Dichtungsstreifen erleichtert, sondern beim Einsetzen des Deckels wird aufgrund der konvergenten Außenumfangsfläche der mit dieser Fläche in Berührung stehende Teil des Dichtungsstreifens nach außen verdrängt und zwischen den in der Ebene des Deckels einander gegenüberliegenden Anlageflächen für den Dichtungsstreifen gedrückt und gegebenenfalls elastisch komprimiert.It is advantageous for the outer peripheral surface of the cover to converge inwards, preferably conical. This will not only assemble the Inserting the lid is easier because the convergent outer peripheral surface Starting slope forms the positioning of the outer peripheral surface in the Sealing strip is facilitated, but when inserting the cover is due to the convergent outer peripheral surface the part in contact with this surface of the weather strip displaced outwards and between those in the plane of the Lid pressed opposite contact surfaces for the sealing strip and optionally elastically compressed.

Im weiteren ist es insbesondere dann, wenn der Dichtungsstreifen in einer Ringausnehmung sitzt, vorteilhaft, am Deckel einen Ringkeil mit einer konvergenten Außenumfangsfläche und einer divergenten Innenumfangsfläche vorzusehen, der vorzugsweise etwa mittig in den Dichtungstreifen drückt und diesen nicht nur in den Grund der Ringnut, sondern auch gegen die Seitenflächen der Ringnut drückt und den Dichtungsstreifen vorzugsweise elastisch komprimiert.Furthermore, it is particularly when the sealing strip in a Ring recess sits, advantageously, a ring wedge with a convergent on the lid Provide outer peripheral surface and a divergent inner peripheral surface, the preferably presses approximately in the middle of the sealing strip and not only in the Reason of the ring groove, but also against the side surfaces of the ring groove and the Sealing strips are preferably elastically compressed.

Gemäß einem vorteilhaften Ausführungsbeispiel kommen betreffende, an der Außenfläche des Deckels austretende Spalte im Bereich der Befestigungsvorrichtung völlig in Fortfall. Dabei ist trotz der nach innen versetzten Anordnung der Befestigungsvorrichtung ein handhabungsfreundliches Schließen und Öffnen des Deckels möglich, weil die Befestigungsvorrichtung durch eine Steckverbindung gebildet ist, deren Steckverbindungsteile beim Einsetzen des Deckels in die Ausnehmung selbsttätig miteinander in Eingriff gelangen und beim Entfernen des Deckels mittels eines den Eingriff überwindenden Kraftaufwandes gelöst werden.According to an advantageous embodiment arrive concerned gap emerging from the outer surface of the cover in the area of the fastening device completely in failure. It is despite the inward arrangement of the Fastening a user-friendly closing and opening of the Lid possible because the fastening device is formed by a plug connection is, its connector parts when inserting the lid into the recess automatically engage with each other and by removing the cover a force that overcomes the intervention can be solved.

Vorzugsweise sind am Deckel keine daran befestigten oder angeformten Angriffselemente zum Entfernen bzw. Öffnen des Deckels vorgesehen, da solche Angriffselemente Spalten bilden könnten, die unerwünscht sind. Ein solcher Deckel ohne betreffende Angriffselemente läßt sich durch die Verwendung von wenigstens einem, vorzugsweise zwei an seine Außenfläche angesetzten Saugköpfen ergreifen und öffnen, wie sie bei der Handhabung von Glasscheiben an sich bekannt und üblich sind.Preferably, there are no attached or molded on the lid Attack elements provided for removing or opening the lid, as such Attack elements could form columns that are undesirable. Such a lid without relevant attack elements can be achieved by using at least grasp one, preferably two suction heads attached to its outer surface and open as they are known and customary when handling glass panes.

In den Unteransprüchen sind Merkmale enthalten, die zum einen die Füllung und Abdichtung des Spaltes verbessern und zum anderen die zwischen dem Deckel und dem Basisgehäuseteil wirksame Befestigungsvorrichtung sowie deren Handhabung bzw. das Einsetzen und Lösen des Deckels verbessern und außerdem zu einfachen, kostengünstig herstellbaren, funktionstüchtigen und kleinen Bauweisen führen. Characteristics are contained in the subclaims, on the one hand the filling and Improve sealing of the gap and secondly the between the lid and the Base housing part effective fastening device and its handling or that Improve insertion and detachment of the lid and also to be simple, inexpensive manufacturable, functional and small designs.

    Zur Montage des Deckels 4 werden die Steckbügel 43 mit ihren Firstabschnitten 43a von innen auf die Aufhänger 56 aufgehängt, wobei die zugehörige Zunge 57b ausweicht und aufgrund ihrer Federelastizität wieder in ihre Verschlußstellung zurückfedert. Dann wird der Deckel in seiner horizontalen Anordnung weiter hochgeschoben, wobei die Firstabschnitte 43a an den Innenseiten der Zungen 57b entlanggleiten und in die Steckschlitze 44 eingeführt werden. Durch einen gewissen Kraftaufwand beim weiteren Hochschieben werden die Verrastungsnasen 48 gegen ihre vorhandene Elastizität eingebogen, wobei sie nach dem Durchgriff in den Steckschlitzen 44 wieder ausbiegen und mit ihren konvergenten bzw. schrägen Verrastungsflanken 43d die Schlitzenden hintergreifen. Aufgrund der elastischen Spreizkraft der Seitenabschnitte 43d wird auch dabei eine nach oben gerichtete Kraftkomponente K auf jeden Steckbügel 43 wirksam, die das vorbeschriebene seitliche Zusammendrücken der Dichtungsabschnitte 31 bewirkt oder - falls der Deckel 4 manuell in diese Position gehoben wird, ein Absenken des Deckels 4 verhindert und somit die Arretierung des Deckels 4 in dieser Position sichert.
