Description

Die vorliegende Erfindung betrifft eine Leuchte nach dem Oberbegriff des Anspruches 1, die insbesondere zur Verwendung in Feuchträumen vorgesehen ist.The present invention relates to a lamp according to the preamble of Claim 1, which is particularly intended for use in wet rooms.

Bei Leuchten, die in Räumen oder Bereichen mit einer hohen Luftfeuchtigkeit zum Einsatz kommen, sind besondere Maßnahmen notwendig, um die Lampen und die elektrischen Komponenten dieser Leuchten vor der Feuchtigkeit zu schützen. Hierzu wird üblicherweise das Leuchtengehäuse, in dem die Lampe sowie die weiteren elektrischen Komponenten angeordnet sind, mit einer durchsichtigen oder durchscheinenden Abdeckung wasserdicht verschlossen.For luminaires that are used in rooms or areas with high humidity Special measures are necessary to use the lamps and the to protect electrical components of these lights from moisture. For this is usually the lamp housing in which the lamp and the others electrical components are arranged with a transparent or translucent cover sealed watertight.

Eine derartige Leuchte ist beispielsweise aus der DE 93 00 896.1 bekannt. Dabei weist die transparente Abdeckung einen Vorsprung auf, der in eine am Rand des Leuchtengehäuses vorgesehene umlaufende Nut hineinragt. Innerhalb dieser Nut befindet sich ein Dichtungsband, welches stark nachgiebig ist und nach dem Zusammenfügen der beiden Elemente den Verbindungsbereich abdichtet. Das Leuchtengehäuse und die darauf aufgesetzte Abdeckung, die beide aus einem formstabilen Material bestehen, werden von mehreren an der Außenseite des Gehäuses angeordneten separaten Klammern zusammengehalten.Such a lamp is known for example from DE 93 00 896.1. It points the transparent cover has a protrusion that fits into one on the edge of the Luminous housing provided circumferential groove protrudes. Within that groove there is a sealing tape which is very flexible and after the Joining the two elements seals the connection area. The Luminaire housing and the cover placed on it, both from one Dimensionally stable material are made of several on the outside of the housing arranged separate brackets held together.

Bei einer in der EP 0 677 698 B1 beschriebenen Feuchtraumleuchte sind über den Rand des Leuchtengehäuses verteilt mehrere Befestigungsklammern angeordnet, die einstückig mit dem Gehäuse verbunden sind. Auch hier weist der Rand des Gehäuses eine umlaufende Nut auf, innerhalb derer ein Dichtungsband angeordnet ist. Eine topfförmige Abdeckung wird von der Unterseite her gegen das Dichtungsband gepreßt und mit Hilfe der Befestigungsklammern mit dem Leuchtengehäuse verbunden, so daß wiederum ein wasserdichter Verschluß gebildet wird.In a moisture-proof luminaire described in EP 0 677 698 B1, over the edge of the lamp housing distributed several mounting brackets, which are integrally connected to the housing. The edge of the housing also points here a circumferential groove, within which a sealing tape is arranged. A Pot-shaped cover is pressed against the sealing tape from the underside and connected to the lamp housing with the help of the fastening clips, so that again a watertight seal is formed.

Bei den oben beschriebenen Leuchten wird die transparente Abdeckung mit Hilfe mehrerer verteilt angeordneter Klammern mit dem Leuchtengehäuse verbunden. Dabei besteht die Gefahr, daß für den Fall, daß eine der Klammern nicht ordnungsgemäß angebracht bzw. geschlossen wurde, kein wasserdichter Verschluß mehr gegeben ist. Darüber hinaus sind für beide oben beschriebenen Leuchten für deren Herstellung zwei Arbeitsgänge notwendig, um die Leuchte wasserdicht bzw. feuchtigkeitsdicht zu verschließen. Zunächst ist das Dichtungsband einzulegen und im Anschluß daran nach dem Aufsetzen der Abdeckung der Verschluß mit Hilfe der einzeln anzubringenden Klammern herzustellen. With the luminaires described above, the transparent cover is removed with the help several distributed brackets connected to the lamp housing. there there is a risk that if one of the brackets is not working properly was attached or closed, there is no longer a watertight seal. In addition, there are two lamps for the manufacture of both described above Operations necessary to make the lamp watertight or moisture-proof close. First insert the sealing tape and then afterwards the placement of the cover with the help of the individually attached To produce brackets.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Leuchte der eingangs beschriebenen Art dahingehend zu verbessern, daß ein wasser- bzw. feuchtigkeitsdichter Verschluß auf einfache und zuverlässige Weise hergestellt werden kann.The present invention has for its object a lamp of the beginning described type to improve that a waterproof or moisture-proof Closure can be made in a simple and reliable manner.

Die Aufgabe wird durch eine Leuchte, welche die Merkmale des Anspruches 1 aufweist, gelöst. Diese Leuchte besteht zunächst aus mindestens einer in einem topfförmigen Leuchtengehäuse angeordneten Lichtquelle sowie aus einer in Abstrahlrichtung vor der mindestens einen Lichtquelle angeordneten und das Leuchtengehäuse verschließenden durchsichtigen oder durchscheinenden Abdeckung, die lösbar mit dem Leuchtengehäuse verbunden ist. Um einen wasserdichter Verschluß zwischen dem Leuchtengehäuse und der Abdeckung, die beide aus einem formstabilen Material bestehen, zu ermöglichen, weisen das Leuchtengehäuse und/oder die Abdeckung über ihren gesamten Umfang hinweg einen aus einem elastischen Material bestehen Klemmrand auf, der zum Verklemmen mit dem gegenüberliegenden Rand der Abdeckung bzw. des Leuchtengehäuses vorgesehen ist. Vorzugsweise ist dieser Klemmrand an dem Leuchtengehäuse angeordnet.The object is achieved by a lamp which has the features of claim 1 has, solved. This lamp initially consists of at least one in one Pot-shaped lamp housing arranged light source and from a in Direction of radiation arranged in front of the at least one light source and that Transparent or translucent cover closing the luminaire housing, which is detachably connected to the lamp housing. A watertight closure between the lamp housing and the cover, both of a dimensionally stable Material exist, to allow the luminaire housing and / or the Cover over its entire circumference made of an elastic material insist on clamping edge, which is for clamping with the opposite edge of the Cover or the lamp housing is provided. This is preferably Clamping rim arranged on the lamp housing.

Bei einer Leuchte gemäß der vorliegenden Erfindung wird somit der Verschluß zwischen der Abdeckung und dem Leuchtengehäuse nicht nur durch einzelne Klammern sondern durch den Klemmrand oder Verrastungsrand hergestellt. Hierdurch wird ein Verschluß über den gesamten Umfang hinweg erzielt, so daß nicht die Gefahr besteht, daß durch das Vergessen einer Klammer ein feuchtigkeitsdichter Verschluß unterbleibt. Ein weiterer Vorteil der erfindungsgemäßen Leuchte besteht darin, daß auf ein zusätzliches Dichtungselement - z.B. das in den oben beschriebenen Leuchten verwendete Dichtungsband - verzichtet werden kann. Hierdurch wird der Arbeitsaufwand bei der Produktion der Leuchten deutlich reduziert.In a lamp according to the present invention, the closure is thus between the cover and the luminaire housing not only by individual clips but produced by the clamping edge or locking edge. This will be a Closure achieved over the entire circumference, so that there is no risk of that a moisture-tight seal is not left by forgetting a clip. Another advantage of the lamp according to the invention is that on a additional sealing element - e.g. that in the lights described above sealing tape used - can be dispensed with. This will Workload in the production of the lights significantly reduced.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Developments of the invention are the subject of the dependent claims.

So ist der Klemmrand vorzugsweise einstückig mit dem Leuchtengehäuse bzw. der Abdeckung verbunden, so daß keine separaten oder zusätzlichen Verschlußelemente notwendig sind. Die erfindungsgemäße Leuchte ist daher auch einfach und kostengünstig herzustellen. Ist der Klemmrand beispielsweise an dem Leuchtengehäuse angeordnet, so bestehen das Gehäuse und der Klemmrand vorzugsweise aus einem thermoplastischen Material, das Gehäuse beispielsweise aus Polycarbonat und der Klemmrand aus einem thermoplatischen Elastomer. Bei der Herstellung des Gehäuses mit dem daran angeordneten Klemmrand in einem Mehrkomponenten-Spritzgußverfahren wird die Verbindungsstelle zwischen diesen beiden Komponenten durch eine chemische Reaktion unter Hitze gebildet, wodurch die beiden Elemente fest aneinander gehalten werden.So the clamping edge is preferably in one piece with the lamp housing or Cover connected so that no separate or additional closure elements are necessary. The lamp according to the invention is therefore also simple and inexpensive to manufacture. Is the clamping edge, for example, on the lamp housing arranged, the housing and the clamping edge preferably consist of one thermoplastic material, the housing made of polycarbonate, for example Clamping rim made of a thermoplastic elastomer. When making the case with the clamping edge arranged on it in a multi-component injection molding process becomes the junction between these two components formed by a chemical reaction under heat, which makes the two elements solid held together.

Der Klemmrand kann beispielsweise in seinem Randbereich ein C-förmiges Profil aufweisen und dann über seine beiden C-Schenkel mit dem gegenüberliegenden Rand verklemmt werden. Dieser weist beispielsweise einen nach außen gerichteten Steg auf, der mit der Wand des Gehäuse bzw. der Abdeckung einen spitzen Winkel einschließt. Vorzugsweise bildet der Klemmrand ferner eine nach unten gerichtet Tropfnase, so daß sich an der Außenseite des Gehäuses bildendes Kondenswasser abtropfen kann.The clamping edge can, for example, have a C-shaped profile in its edge area and then over its two C-legs with the opposite edge be jammed. This has, for example, an outwardly directed web, which forms an acute angle with the wall of the housing or the cover. Preferably, the clamping edge also forms a downward drip nose, so that condensation forming on the outside of the housing can drip off.

Im folgenden soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. Es zeigen:

Fig. 1

Fig. 2
einen Ausschnitt A von Fig. 1 in vergrößerter Darstellung.
The invention will be explained in more detail below with reference to the accompanying drawing. Show it:
Fig. 1
an embodiment of a lamp according to the invention in section; and
Fig. 2
a section A of Fig. 1 in an enlarged view.

Fig. 1 zeigt die erfindungsgemäße Leuchte in geschlossenem Zustand, wobei zur Vereinfachung der Darstellung lediglich die erfindungswesentlichen Elemente der Leuchte dargestellt sind. Innerhalb des topfförmigen Leuchtengehäuses 1, das beispielsweise an einer Decke zu befestigen ist, befindet sich zumindest eine Lichtquelle 3, wobei es sich hierbei beispielsweise um eine Glühbirne oder eine längliche Leuchtstofflampe handeln kann. Die Form des Leuchtengehäuses 1 richtet sich dabei nach der Art und Anzahl bzw. Anordnung der Lichtquellen.Fig. 1 shows the lamp according to the invention in the closed state, with the Simplification of the representation of only the essential elements of the invention Luminaire are shown. Within the pot-shaped lamp housing 1, the For example, to be attached to a ceiling, there is at least one light source 3, this being, for example, a light bulb or an elongated one Fluorescent lamp can act. The shape of the lamp housing 1 depends according to the type and number or arrangement of the light sources.

Das nach unten offene Leuchtengehäuse 1 ist durch eine durchsichtige oder zumindest durchscheinende Abdeckung 2 wasser- bzw. feuchtigkeitsdicht verschlossen. Hierzu weist das Leuchtengehäuse 1 einen über den gesamten Umfang hinweg verlaufenden elastischen Klemmrand 4 auf, in den der Randbereich der Abdeckung 2 eingeklemmt wird. Der Klemmrand 4 ist vorzugsweise ein Verrastungsrand mit einer Verrastungsnase 41, die beim Ausführungsbeispiel umlaufend ausgebildet ist.The downward open lamp housing 1 is transparent or at least translucent cover 2 sealed watertight or moisture-proof. For this the luminaire housing 1 extends over the entire circumference elastic clamping edge 4, in which the edge region of the cover 2 is clamped becomes. The clamping edge 4 is preferably a locking edge with a Locking lug 41, which is formed all around in the embodiment.

Die nähere Ausgestaltung des Klemmrandes 4 ist in vergrößerter Darstellung in Fig. 2 gezeigt. Der Klemmrand 4 besteht dabei aus einem elastischen Material und weist in seinem Randbereich ein C-förmiges Profil auf, welches beim Verschließen der Leuchte mit einem am Rand der Abdeckung 2 angeordneten Steg 5 verklemmt wird. Der nach außen gerichtete Steg 5 ist nach außen geneigt angeordnet und schließt beim Ausführungsbeispiel mit einer schalenförmigen Abdeckung 2 mit der Seitenwand der Abdeckung 2 einen spitzen Winkel ein. The closer configuration of the clamping edge 4 is shown in an enlarged view in FIG. 2 shown. The clamping edge 4 consists of an elastic material and has in its edge area on a C-shaped profile, which when closing the lamp is clamped with a web 5 arranged on the edge of the cover 2. The after externally directed web 5 is inclined outwards and closes at Embodiment with a bowl-shaped cover 2 with the side wall of the Cover 2 at an acute angle.

Aufgrund der nach außen geneigten Anordnung des Steges 5 ist sein innerer Stegrand 5a bezüglich seinem äußeren Stegrand 5b nach oben versetzt. Dabei bildet die geneigte Oberseite eine divergente Einführungsfläche 5c auf der beim Klemmen oder Verrasten der Klemm- oder Verrastungsrand nach außen gedrängt wird. Die beim Ausführungsbeispiel schmale Seitenfläche des Steges 5 ist konvergent hinterschnitten. Hierdurch kann die Verrastungsnase 4a den Steg 5 hintergreifen und verrasten. Außerdem ist dadurch eine divergente Ausführungsfläche 5d gebildet, auf der die Verrastungsnase 4a beim Lösen der Verrastung nach außen gedrängt wird.Due to the outwardly inclined arrangement of the web 5 is its inner web edge 5a offset upwards with respect to its outer web edge 5b. It forms the inclined Top of a divergent insertion surface 5c on the clamping or locking the clamping or locking edge is pushed outwards. The at Embodiment narrow side surface of the web 5 is undercut convergent. As a result, the latching nose 4a can engage behind the latch 5 and latch. This also forms a divergent execution surface 5d on which the Locking nose 4a is pushed outwards when the locking is released.

In der montierten Stellung untergreift der untere C-Schenkel 6 des Klemmrandes 4 oder Verrastungsrades den Steg, während der obere C-Schenkel 7 eine nach innen ragende Lippe bildet, die an die Oberseite des Stegs 5 bzw. an den Stegrand 5a anschlägt. Die beiden C-Schenkel 6, 7 stehen beim Einklemmen des Stegs 5 unter Spannung und gewährleisten sowohl einen sicheren Halt der Abdeckung 2 an dem Leuchtengehäuse 1 als auch den gewünschten, dichten, insbesondere wasserdichten Verschluß. Ein zusätzliches Dichtelement wie beispielsweise ein Dichtungsband oder dergleichen ist nicht mehr notwendig.In the assembled position, the lower C-leg 6 engages under the clamping edge 4 or Verrastungsrades the web, while the upper C-leg 7 an inwardly projecting Lip forms which abuts the top of the web 5 or the web edge 5a. The Both C-legs 6, 7 are under tension and when clamping the web 5 ensure a secure hold of the cover 2 on the lamp housing 1 as well as the desired, tight, especially watertight closure. On additional sealing element such as a sealing tape or the like not necessary anymore.

Vorzugsweise ist der den Steg 5 untergreifende C-Schenkel 6 des Klemmrandes 4 ferner so geformt, daß er eine nach unten gerichtete Tropfnase bildet. Kondenswasser, daß sich an der Außenseite des Leuchtengehäuses 1 bildet und nach unten abläuft kann dann nach unten abtropfen und nicht in den Verbindungsbereich zwischen dem Klemmrand 4 und der Abdeckung 2 eindringen.The C-leg 6 of the clamping edge 4, which engages under the web 5, is preferably furthermore shaped so that it forms a downward drip nose. Condensation that forms on the outside of the lamp housing 1 and can then run down drip down and not into the connection area between the clamping edge 4 and the cover 2 penetrate.

Das ebenfalls nach außen geneigt angeordnete C-förmige Profil des Klemmrandes kann sich im Bereich seines Basisabschnittes 4b gerade (nicht dargestellt) oder gekrümmt (dargestellt), vorzugsweise nach oben konvex gekrümmt, erstrecken. Dabei kann es an eine Randbasis 4c angeformt sein, die eine seitliche Verlängerung des vorzugsweise hut- oder domförmigen Leuchtengehäuses 1 sein kann.The C-shaped profile of the clamping edge, which is also inclined outwards, can straight (not shown) or curved in the region of its base section 4b (shown), preferably convexly curved upwards. It can be formed on an edge base 4c, which is preferably a lateral extension of the hat or dome-shaped lamp housing 1 can be.

Neben dem Klemmrand 4 ist an dem Leuchtengehäuse 1 ferner ein nach unten gerichteter Steg 8 angeordnet. Dieser in Verbindungsrichtung zwischen dem Gehäuse 1 und der Abdeckung 2 gerichtete Steg 8 bildet einen Führungssteg, durch den das Anbringen der Abdeckung 2 an der Unterseite des Leuchtengehäuses 1 erleichtert wird.In addition to the clamping edge 4 on the lamp housing 1 is also a down directed web 8 arranged. This in the direction of connection between the housing 1 and the cover 2 directed web 8 forms a guide web through which Attaching the cover 2 on the underside of the lamp housing 1 is facilitated.

Das Leuchtengehäuse 1 und der Klemmrand 4 sind vorzugsweise einstückig miteinander verbunden und bestehen aus einer harten bzw. weichen Komponente, die beide thermoplastisch sind. Die Hartkomponente des Gehäuses 1 besteht beispielsweise aus Polycarbonat, während die Weichkomponente des Klemmrandes 4 aus einem thermoplastischen Elastomer besteht. Das Gehäuse 1 mit dem daran angeordneten Klemmrand 4 kann beispielsweise in einem Mehrkomponenten-Spritzgußverfahren hergestellt werden. Die Verbindungsstelle zwischen der Hart- und Weichkomponente wird dann durch eine chemische Reaktion unter Hitze gebildet, so daß der Klemmrand 4 fest mit dem Gehäuse 1 verbunden ist. Der Klemmrand 4 kann dabei zur besseren Unterscheidung gegenüber dem Gehäuse 1 eine andere Farbe aufweisen.The lamp housing 1 and the clamping edge 4 are preferably in one piece with one another connected and consist of a hard or soft component, both are thermoplastic. The hard component of the housing 1 consists, for example, of Polycarbonate, while the soft component of the clamping edge 4 from one thermoplastic elastomer. The housing 1 with the arranged thereon Clamping edge 4 can, for example, in a multi-component injection molding process getting produced. The connection point between the hard and soft components is then formed by a chemical reaction under heat, so that the clamping edge 4 is firmly connected to the housing 1. The clamping edge 4 can be better Differentiation from the housing 1 have a different color.

Durch die in den Figuren dargestellte Konfiguration des Klemmrandes 4 wird eine besonders gute Abdichtung erzielt, wobei gleichzeitig ein einfaches Anbringen bzw. Entfernen der Abdeckung 2 ermöglicht wird. Es sind allerdings auch andere Strukturen für den Klemmrand 4 bzw. den gegenüberliegenden Randbereich in der Abdeckung 2 denkbar, durch die eine geeignete Klemmwirkung erzielt wird. Ferner wäre es auch denkbar, daß nicht das Leuchtengehäuse 1 sondern die Abdeckung 2 einen aus einem elastischem Material bestehenden Klemmrand aufweist, der in geeigneter Weise mit dem gegenüberliegenden Rand zur Befestigung der Abdeckung 2 an dem Gehäuse 1 verklemmt werden kann. Auch wäre es denkbar, daß sowohl das Gehäuse 1 als auch die Abdeckung 2 einen aus elastischem Material bestehenden Klemmrand aufweisen.Due to the configuration of the clamping edge 4 shown in the figures, a achieved particularly good sealing, while at the same time simple attachment or Removing the cover 2 is made possible. However, there are other structures for the clamping edge 4 or the opposite edge area in the cover 2 conceivable by which a suitable clamping effect is achieved.
