Abstract

For the purpose of forming a housing, a lower housing part (10) is provided with a housing cover in such a way that the housing cover is mounted on the lower housing part by means of hinges (12, 13). In order to avoid stress cracking corrosion and stress cracks in the housing cover (20), a frame (14) is provided which has a depression (19) into which the free edge of the housing cover (20) is inserted and locked therein and fixed therein by means of a mouldable or injectable sealing compound (24) which is filled into the depression (29) after insertion of the edge of the housing cover (20). The individual joining or mounting elements of the housing cover (20) on the lower housing part (10) are attached to the frame (14). This results in a stress-free mounting of the housing cover (20) on the lower housing part. This arrangement is preferably applied in light fixtures with fluorescent lamps in which the housing cover corresponds to the light fixture trough. <IMAGE>

Description

Die Erfindung betrifft ein Gehäuse gemäß dem Oberbegriff des Anspruches 1.The invention relates to a housing according to the preamble of claim 1.

Leuchtengehäuse für Langfeld-Leuchtstofflampen bestehen im allgemeinen aus einem Gehäuseunterteil, das aus hochfestem Material hergestellt ist, und einem Gehäuseoberteil bzw. einer Gehäuseabdeckung, das aus transparentem Material hergestellt ist, und beide Gehäuseteile werden im allgemeinen so miteinander verbunden, daß die Abdeckung zum Austausch der Leuchtstofflampen entfernt werden kann. Das bedeutet, daß an der Gehäuseabdeckung, auch Leuchtenwanne genannt, Scharniere, Schrauben und dergleichen vorgesehen sein müssen, damit insbesondere bei explosionsgeschützten Leuchten eine bestimmte Dichtigkeit des Leuchtengehäuses erreicht wird. Die Abdeckung der bekannten Leuchtengehäuse ist daher einer mechanischen Spannung unterworfen, wobei an bestimmten Stellen, insbesondere an den eigentlichen Befestigungs stellen und an den Verschlußpunkten Spannungsspitzen vorhanden sind.Luminaire housings for linear fluorescent lamps generally consist of a lower housing part, which is made of high-strength material, and a housing upper part or a housing cover, which is made of transparent material, and both housing parts are generally connected to one another so that the cover for exchanging the Fluorescent lamps can be removed. This means that hinges, screws and the like must be provided on the housing cover, also called luminaire trough, so that a certain tightness of the luminaire housing is achieved, in particular in the case of explosion-protected luminaires. The cover of the known luminaire housing is therefore subjected to mechanical tension, being at certain points, in particular at the actual fastening and there are voltage peaks at the locking points.

Wenn die Leuchtenabdeckung aus Thermoplast hergestellt ist, dann ist damit zu rechnen, daß Spannungsrisse auftreten, z.B. dann, wenn das Leuchtengehäuse aggressiven Chemikalien etc. benetzt wird. Derartige Reinigungsmittel nämlich sind im allgemeinen aggressiv für Thermoplaste und Glas und können zu Spannungsrißkorrosion führen, insbesondere wenn diese Teile unter mechanischer Spannung stehen.If the lamp cover is made of thermoplastic, stress cracks are likely to occur, e.g. when the luminaire housing is wetted by aggressive chemicals etc. Such cleaning agents are generally aggressive for thermoplastics and glass and can lead to stress corrosion cracking, especially if these parts are under mechanical stress.

Derartige Spannungsrisse müssen schon deshalb vermieden werden, damit die Umgebungsatmosphäre nicht ins Innere des Leuchtengehäuses eindringen kann.Such stress cracks must be avoided so that the ambient atmosphere cannot penetrate into the interior of the luminaire housing.

Ähnliche Probleme gibt es nicht nur bei Leuchtengehäusen, sondern bei allen denjenigen Gehäusen, bei denen an einem Gehäuseunterteil eine Abdeckung anzubringen ist, bei der eine bestimmte Dichtigkeit, z.B. eine Schwadendichtigkeit, erreicht werden muß.Similar problems exist not only with luminaire housings, but also with all those housings in which a cover has to be attached to a lower housing part, in which a certain tightness, e.g. a vapor tightness must be achieved.

Aufgabe der Erfindung ist es daher, ein Gehäuse der eingangs genannten Art zu schaffen, bei dem die Gefahr von Spannungsrissen vermieden oder zumindest stark reduziert ist.The object of the invention is therefore to provide a housing of the type mentioned in the introduction in which the risk of stress cracks is avoided or at least greatly reduced.

Diese Aufgabe wird erfindungsgemäß gelöst durch die kennzeichnenden Merkmale des Anspruches 1.This object is achieved according to the invention by the characterizing features of claim 1.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention can be found in the subclaims.

Dadurch, daß der Rand der Gehäuseabdeckung mit dem Rahmen versehen ist und daß die einzelnen Verbindungsmittel, wie z.B. die Schrauben, Scharniere und dergleichen am Rahmen angeformt sind, ist es möglich, die Gehäuseabdeckung praktisch spannungsfrei an dem Gehäuseunterteil zu befestigen. Ein weiterer besonderer Vorteil der erfindungsgemäßen Ausgestaltung besteht darin, daß die Gehäuseabdeckung sehr einfach ausgebildet sein kann, weil die einzelnen Mittel, die zur Verbindung mit dem Gehäuseunterteil vorzusehen sind, nicht mehr an der Abdeckung anzuformen sind. Dies bedeutet neben einer erheblichen Verringerung der Werkzeugkosten auch eine Verbesserung der äußeren Form und eine Vereinfachung in der Anzahl der für eine Leuchtenserie erforderlichen Abdeckungen. Die Leuchtenabdeckung kann dabei ausschließlich nach Kriterien betreffend die Leuchtenleistung ausgewählt werden; andere Kriterien sind von geringer Bedeutung. Darüberhinaus ist auch die Herstellung einer antistatischen Gehäuseabdeckung wegen der einfachen Geometrie der Abdeckung und des Materials des Andruckrahmens möglich. Das Gehäuseunterteil, die Dichtung, der Rahmen und die Vergußmasse bzw. Hohlraumdichtung, mit der der Rahmen und die Gehäuseabdeckung miteinander verbunden bzw. gegeneinander abgedichtet sind, können mit einfachen Maßnahmen antistatisch eingestellt werden, d.h. einen Oberflächenwiderstand von 109 Ohm erhalten. Auf die Außenfläche der Gehäuseabdeckung kann auch wegen der fehlenden Kanten und wegen Fehlens von zusätzlichen Ausformungen für Scharniere und dergleichen eine geeignete Folie aus Aufladungen ableitendem Material in Form eines Gitters aufgetragen werden, so daß die Flächen innerhalb der einzelnen Gittermaschen die sich aufladen können, vorschriftsmäßig klein sind. Wegen der speziellen äußeren Form ist auch ein Siebgitter durch Lackauftrag oder ein Zweikomponentenspritz-Verfahre ohne weiteres möglich. Dies liegt einzig nur an der einfachen äußeren Form. Die Abdeckung kann dabei aus beliebigem transparenten Materialien.bestehen; sofern das Schwundmaß dieser Materialien beachtet wird.Characterized in that the edge of the housing cover is provided with the frame and that the individual connecting means, such as the screws, hinges and the like, are molded onto the frame, it is possible to fasten the housing cover to the lower part of the housing practically without tension. Another particular advantage of the configuration according to the invention is that the housing cover can be made very simple because the individual means which are to be provided for connection to the lower housing part no longer have to be molded onto the cover. In addition to a significant reduction in tool costs, this also means an improvement in the external shape and a simplification in the number of covers required for a series of luminaires. The luminaire cover can only be selected according to criteria relating to the luminaire output; other criteria are of little importance. In addition, it is also possible to produce an antistatic housing cover because of the simple geometry of the cover and the material of the pressure frame. The lower housing part, the seal, the frame and the potting compound or cavity seal, with which the frame and the housing cover are connected to one another or sealed against one another, can be adjusted antistatically with simple measures, ie a surface resistance of 109 ohms can be obtained. A suitable film of charge-dissipating material in the form of a grid can also be applied to the outer surface of the housing cover because of the missing edges and due to the lack of additional formations for hinges and the like, so that the areas within the individual grid meshes that can charge up are small according to regulations are. Due to the special outer shape, a sieve screen is also through Paint application or a two-component spray process possible without further ado. This is only due to the simple outer shape. The cover can consist of any transparent materials. provided that the shrinkage of these materials is observed.

Die Leuchte bzw. das Leuchtengehäuse gemäß Figur 1 besteht aus einem langgestreckt rechteckigen, topfartigen Gehäuseunterteil 10, dessen freier Rand einen L-förmig nach außen gerichteten, am Rand umlaufenden Fortsatz 11 aufweist. Auf der rechten Seite besitzt der Fortsatz 11 zwei Bügel 12, in die an einem Rahmen 14 angeformte Achsen bzw. Zapfen 13 eingehängt sind (siehe weiter unten Figuren 2 bzw. 4). Auf der gegenüberliegenden Längskante ist ein Haltemittel in Form eines Verriegelungselementes 15 auf der Innenseite des Gehäuseunterteils 10 befestigt, das mit Verriegelungszapfen 16 in nicht näher dargestellte Ausnehmungen am Rahmen 14 zwecks Verschließens eingefügt werden können. Der Rahmen, der einen umlaufenden, der Randkontur des Gehäuseunterteils 10 angepaßten Ring bildet, besitzt auf der einen Ringfläche eine U-förmige Leistenanordnung 17, in die eine umlaufende Dichtung 18 eingesetzt ist. Auf der überliegenden Fläche des Rahmens 14 ist eine Vertiefung 19 vorgesehen, in die der freie Rand einer Gehäuseabdeckung, hier einer Abdeckwanne 20 eingesetzt ist. Die Vertiefung bzw. die umlaufende Nut 19 besitzt auf ihrer äußeren Innenfläche 21 Nasen 22, hinter die ein an der Abdeckwanne 20 angeformter, radial nach außen verlaufender Flanschrand 23 geschnappt werden kann. Danach wird die Nut 19 mit Gießharz 24 oder einem ähnlichen Abdichtmittel ausgegossen.The luminaire or luminaire housing according to FIG. 1 consists of an elongated, rectangular, pot-like lower housing part 10, the free edge of which has an L-shaped outward extension 1 1 running around the edge. On the right-hand side, the extension 11 has two brackets 12, into which axes or pins 13 formed on a frame 14 are suspended (see FIGS. 2 and 4 below). On the opposite longitudinal edge, a holding means in the form of a locking element 15 is fastened on the inside of the lower housing part 10, which can be inserted with locking pins 16 into recesses in the frame 14, not shown, for the purpose of closing. The frame, which forms a circumferential ring which is adapted to the edge contour of the lower housing part 10, has on one ring surface a U-shaped strip arrangement 17 into which a circumferential seal 18 is inserted. A recess 19 is provided on the overlying surface of the frame 14, into which the free edge of a housing cover, here a cover trough 20, is inserted. The depression or the circumferential groove 19 has lugs 22 on its outer inner surface, behind which a flange rim 23 which is formed on the cover trough 20 and extends radially outwards can be snapped. The groove 19 is then poured out with casting resin 24 or a similar sealant.

Im Inneren des Leuchtengehäuses befinden sich Leuchtstofflampen 25 und 26, die dort in an sich bekannter Weise befestigt sind.In the interior of the lamp housing there are fluorescent lamps 25 and 26 which are fastened there in a manner known per se.

Es sei nun bezug genommen auf die Figur 2. Man erkennt dort eine schematische Darstellung des Rahmens 14, gemäß Blickrichtung B. Nicht dargestellt ist die Doppellei stenanordnung 17 und demgemäß ist auch die Dichtung anders ausgebildet. Man erkennt auf der rechten Seite die beiden Zapfen 13, die in den Bügel 12 am Gehäuseunterteil eingehängt werden können bzw. bei der Ausführung nach Figur 4 auch eingehängt dargestellt sind. Die Dichtung 18 ist in eine Nut 27 in dem Fortsatz 11 eingelassen.Reference is now made to FIG. 2. A schematic representation of the frame 14 can be seen there, in the viewing direction B. The double egg is not shown most arrangement 17 and accordingly the seal is designed differently. One can see on the right side the two pins 13 which can be hooked into the bracket 12 on the lower housing part or are also shown hooked in the embodiment according to FIG. The seal 18 is embedded in a groove 27 in the extension 11.

Man erkennt aus der Ausführung nach Figur 3, daß die Abdeckwanne 20 an ihrem freien Ende eine Rastnase 28 aufweist, mit der sie hinter einen Vorsprung 29 greift, der der Nase 22 entspricht. Tatsächlich sind mehrere Vorsprünge 29 vorhanden, damit die Abdeckwanne 20 ausreichend gut an dem Rahmen befestigt werden kann. In dem Bereich der Rastnasen 28 besitzt die Abdeckwanne 20 auf ihrer Innenfläche einen Bereich 30 mit verringerter Wandstärke; dadurch ist die Abdeckwanne 20 im Bereich der Rastnasen 28 leichter elastisch verformbar. Man erkennt darüberhinaus auch das in die Vertiefung 19 eingelassene Dichtungsmittel 24.It can be seen from the embodiment according to FIG. 3 that the cover trough 20 has at its free end a latching lug 28 with which it engages behind a projection 29 which corresponds to the lug 22. In fact, there are several projections 29 so that the cover trough 20 can be attached to the frame sufficiently well. In the area of the locking lugs 28, the cover trough 20 has an area 30 with reduced wall thickness on its inner surface; As a result, the cover trough 20 is more easily elastically deformable in the region of the locking lugs 28. The sealant 24 let into the recess 19 can also be seen.

Die Figuren 5 und 6 zeigen andere Ausgestaltungen der Festlegung der Abdeckwanne 20 an einem Rahmen. Der Rahmen 50 gemäß Figur 5 besitzt eine umlaufende Vertiefung 51, die der Vertiefung 19 entspricht. In den Rahmen 50 sind mehrere Bohrungen 52 eingebracht, durch die hindurch Stopfen 53 bzw. Bolzen 53 eingefügt werden; nach Einfügen des Randes der Wanne 20 in die Vertiefung 51 und Einfügen des Stopfens 53 in den Bereich des flanschartigen Kragens 54 wird die Vertiefung mit Gießharz oder ähnlichem Dichtungsmaterial 55 ausgegossen und die Abdeckwanne ist am Rahmen fixiert. Bei der Figur 6 wird anstatt eines Stopfens 53 eine Fixierungsleiste 56 hinter den Vorsprung 57, der dem Vorsprung 29 der Figur 3 entspricht, eingelegt und danach ebenfalls wieder die Vertiefung mit Gießharz 58 oder einem ähnlichen Material ausgegossen. Auch hier wird eine einwandfreie und gute Fixierung der Abdeckwanne 20 am Rahmen 50 bewirkt.Figures 5 and 6 show other embodiments of the fixing of the cover 20 on a frame. The frame 50 according to FIG. 5 has a circumferential depression 51, which corresponds to the depression 19. Several bores 52 are made in the frame 50, through which plugs 53 and bolts 53 are inserted; after inserting the edge of the tub 20 into the depression 51 and inserting the plug 53 into the region of the flange-like collar 54, the depression is poured out with casting resin or similar sealing material 55 and the covering tub is fixed to the frame. In FIG. 6, instead of a plug 53, a fixing strip 56 is placed behind the projection 57, which corresponds to the projection 29 in FIG. 3 corresponds, inserted and then again poured the recess with casting resin 58 or a similar material. Here too, the cover pan 20 is properly and properly fixed to the frame 50.

In der Ausgestaltung gemäß Figur 7 besitzt der Rahmen 70, der dem Rahmen 14 in etwa gleicht, eine Nut 71, die eine der Nase 19 gleichende Nase 72 aufweist. Der freie Rand des Leuchtengehäuses (Abdeckwanne) 20 ist abgerundet.In the embodiment according to FIG. 7, the frame 70, which is approximately the same as the frame 14, has a groove 71 which has a nose 72 which is similar to the nose 19. The free edge of the lamp housing (cover trough) 20 is rounded.

In die Nut 71, hinter die Nase 72 einrastend ist eine umlaufende Dichtung 73 eingesetzt, die einen Hohlraum 74 umfaßt und damit elastisch verformbar ist. Damit wird der rastnasenförmige Gehäuserand 28 von der Hohlraumdichtung 73/74 gegen die Nase 72 gedrückt und am Rahmen so spannungsfrei festgehalten. Ein Herausfallen der Abdeckwanne wird durch nicht näher dargestellte mechanische, spannungsfrei auf die Abdeckwanne wirkende Halterungen erreicht.A circumferential seal 73 is inserted into the groove 71, snapping behind the nose 72, which comprises a cavity 74 and is thus elastically deformable. The lug-shaped housing edge 28 is thus pressed against the nose 72 by the cavity seal 73/74 and is thus held on the frame without tension. Falling out of the cover trough is achieved by means of holders, not shown in detail, which act on the cover trough without tension.

Die Figur 8 zeigt einen Rahmen 80 mit Nut 81 ohne eine der Nase 72 entsprechende Nase. In die Nut 81 ist eine Dichtung 82 in Form von Gießharz eingegossen, in die der Rand der Abdeckwanne eingegossen ist. Dieses "Eingießteil" kann natürlich auch ein vorgeformtes Dichtungsteil sein, das teilschlüssig in der Nut festgehalten ist.FIG. 8 shows a frame 80 with a groove 81 without a nose corresponding to the nose 72. In the groove 81, a seal 82 is poured in the form of casting resin, in which the edge of the cover trough is poured. This "pouring part" can of course also be a preformed sealing part which is held in the groove in a partially integral manner.

Figur 9 zeigt eine der Figur 7 ähnliche Ausgestaltung. Der Rahmen 90 besitzt eine Nut 91 ähnlichen der Nut 71 mit einer nach innen in die Nut hineinragende Nase 92 an deren äußeren oberen Ende. In die Nut hinter die Nasen 92 ist eine Dichtung 93 mit einem Hohlraum 94 und einer L-förmigen Lippe 95 eingesetzt, wobei die Lippe 95 den Rand der Abdeckwanne übergreift und die Abdeckwanne festhält.Figure 9 shows an embodiment similar to Figure 7. The frame 90 has a groove 91 similar to the groove 71 with a nose 92 protruding inward into the groove at its outer upper end. A seal 93 with a cavity 94 and an L-shaped lip 95 is inserted into the groove behind the lugs 92, the lip 95 being the Reaches over the edge of the cover trough and holds the cover trough.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Abdeckwanne 20 in der Vertiefung 19, 51, 71, 81, 91 praktisch völlig spannungsfrei eingesetzt und darin auch spannungsfrei gehaltert ist. Damit muß die Wanne nicht mehr für Dichtungszwecke herangezogen werden; vielmehr ist hierfür der Rahmen 14, 50, 70, 80, 90 vorgesehen, der aus geeignetem Material hergestellt sein kann und demgemäß eine ausreichende Festigkeit aufweisen muß. An diesem Rahmen sind die einzelnen Verschlußelemente wie Scharnier und ggf. Schraubenelemente angeformt, wodurch die Herstellung der Wanne erheblich vereinfacht ist.The advantages achieved by the invention are, in particular, that the cover trough 20 is used in the recess 19, 51, 71, 81, 91 practically completely free of tension and is also held in it free of tension. So that the tub no longer has to be used for sealing purposes; rather, the frame 14, 50, 70, 80, 90 is provided for this purpose, which can be made of a suitable material and must accordingly have sufficient strength. The individual closure elements such as hinge and possibly screw elements are molded onto this frame, which considerably simplifies the manufacture of the tub.
