Description

Die vorliegende Erfindung betrifft eine überfahrbare Bodeneinbauleuchte nach dem Oberbegriff des Anspruchs 1.The present invention relates to a retractable ground recessed luminaire according to the preamble of claim 1.

Bodeneinbauleuchten, welche befahrbar sind und überrollt werden können, sind allgemein Stand der Technik. An derartige Bodeneinbauleuchten werden besondere Anforderungen hinsichtlich der Robustheit gestellt. Insbesondere müssen die Glasscheiben, die als Abdeckung der Lichtaustrittsöffnung einer überfahrbaren Bodeneinbauleuchte verwendet werden, besonders hohen Belastungen Stand halten, da sie Teil der Fahrbahn bzw. Teil des überfahrbaren Bodenbelags sind. Die Abdeckglasscheibe einer überfahrbaren Bodeneinbauleuchte ist zumeist horizontal ausgerichtet, jedenfalls sofern die Fahrbahn kein Gefälle aufweist. Die im Folgenden verwendeten Richtungsangaben beziehen sich auf die Standardeinbausituation einer überfahrbaren Bodeneinbauleuchte, wonach sowohl Fahrbahn als auch Glasscheibe horizontal ausgerichtet sind. Es versteht sich von selbst, dass die Bodeneinbauleuchte der vorliegenden Erfindung auch in Fällen zum Einsatz kommen kann, wo die Fahrbahn ein Gefälle aufweist und somit die Glasscheibe der Bodeneinbauleuchte ebenfalls eine von der Horizontalen abweichende Ausrichtung aufweist.Ground recessed lights, which are passable and can be rolled over, are generally state of the art. At such ground recessed luminaires special requirements are made in terms of robustness. In particular, the glass sheets, which are used as a cover of the light exit opening of a retractable ground light, particularly high loads withstand, since they are part of the lane or part of the drive over flooring. The cover glass of a retractable recessed ground luminaire is usually aligned horizontally, at least if the roadway has no slope. The directions given below refer to the standard installation situation of a retractable in-ground luminaire, according to which both the carriageway and the glass are aligned horizontally. It goes without saying that the recessed ground light of the present invention can also be used in cases where the roadway has a slope and thus the glass of the recessed ground light also has a different orientation from the horizontal.

Neben dem Erfordernis der Robustheit von Bodeneinbauleuchte und Abdeckglasscheibe besteht bei überfahrbaren Bodeneinbauleuchten zusätzlich die Anforderung einer äußerst guten Abdichtung zwischen Glasscheibe und Leuchtengehäuse, sodass kein Wasser in die Leuchte eindringen kann.In addition to the requirement of the robustness of recessed floor luminaire and cover glass, the floor recessed luminaires also require a very good seal between the glass pane and luminaire housing so that no water can penetrate into the luminaire.

Eine überfahrbare Bodeneinbauleuchte ist beispielsweise aus der DE 102006060371 A1 bekannt. Die aus dieser Offenlegungsschrift bekannte Bodeneinbauleuchte ist gegenüber dem Gehäuse mittels einer weichelastischen Dichtung abgedichtet, wobei die Dichtung den Rand der Glasscheibe C-förmig umschließt. Die Glasscheibe liegt somit sowohl mit ihrer Unterseite als auch mit dem Rand direkt an der weichelastischen Dichtung an. Der Rand der Glasscheibe ist zudem ausgehend von der Oberseite stufenförmig abgesetzt, sodass die weichelastische Dichtung die untere Stufe des Randes oberseitig umschließen kann, ohne dabei über die Oberseite der Glasscheibe hinauszuragen.An overridden ground recessed light is for example from the DE 102006060371 A1 known. The ground recessed luminaire known from this publication is sealed relative to the housing by means of a soft-elastic seal, the seal enclosing the edge of the glass pane C-shaped. The glass pane thus lies directly against the soft-elastic seal both with its underside and with the edge. The edge of the glass pane is also stepped from the top so that the soft elastic seal can enclose the lower step of the edge on the upper side without protruding beyond the top of the glass pane.

Eine weitere überfahrbare Bodeneinbauleuchte mit einer Dichtung, die den Rand der Glasscheibe umlaufend C-förmig umschließt, ist aus DE 102004009632 A1 bekannt. Auch hier ist der Rand der Glasscheibe stufenförmig abgesetzt, sodass die Oberseite der Glasscheibe auf dem Niveau der Fahrbahn liegt und keine Dichtungs- oder Blendenteile über dieses Niveau hinausgehen. Die umlaufende weichelastische Dichtung ist zwischen der Glasscheibe und einem Flansch des Leuchtengehäuses angeordnet.Another retractable recessed ground luminaire with a seal that encloses the edge of the glass C-shaped circumferential is out DE 102004009632 A1 known. Again, the edge of the glass pane is stepped, so that the top of the glass is at the level of the carriageway and there are no seals or panels beyond this level. The circumferential soft elastic seal is disposed between the glass sheet and a flange of the lamp housing.

Eine weitere Bodeneinbauleuchte mit dem oben beschriebenen Dichtungsprinzip ist aus DE 10013304 B4 bekannt.Another ground recessed luminaire with the sealing principle described above is off DE 10013304 B4 known.

Das Dichtungsprinzip der aus dem Stand der Technik bekannten überfahrbaren Bodeneinbauleuchten hat zur Folge, dass die Glasscheibe aufgrund der den Rand der Glasscheibe umschließenden Dichtung sozusagen schwimmend gelagert ist und sich aufgrund der Elastizität der Dichtung und der auf die Glasscheibe wirkenden Lasten gegenüber dem Leuchtengehäuse bewegen kann. Dies führt bei statischer Belastung auch unter hoher Lasteinwirkung nicht zu Problemen. Auch bei dynamischer Belastung bieten die aus dem Stand der Technik bekannten Dichtungen einen guten Schutz beispielsweise vor Eindringen der Feuchtigkeit, solange die Wechselbelastung langsam erfolgt. Bei hoher und insbesondere hochfrequenter dynamischer Belastung ist die Dichtung jedoch nicht in der Lage, den schnellen Bewegungen der Glasscheibe zu folgen, wodurch Feuchtigkeit und Schmutz in das Leuchtengehäuse eintreten können. Unabhängig davon, ob die Belastung auf die Glasschreibe nun statisch oder dynamisch erfolgt, geht mit der Belastung ein Verschleiß der Dichtung einher, wovon insbesondere der Teil der Dichtung betroffen ist, auf dem die Glasscheibe mit ihrer Unterseite aufliegt.The sealing principle of the known from the prior art retractable recessed ground lights has the consequence that the glass pane is floating due to the edge of the glass enclosing seal so to speak floating and can move due to the elasticity of the seal and acting on the glass loads against the lamp housing. This does not cause problems under static load even under high load. Even under dynamic load, the known from the prior art seals provide good protection, for example, against the ingress of moisture, as long as the alternating load is slow. However, at high and in particular high-frequency dynamic load, the seal is not able to follow the rapid movements of the glass, whereby moisture and dirt can enter the luminaire housing. Regardless of whether the load on the glass writing is now static or dynamic, the load is accompanied by wear of the seal, which in particular affects the part of the seal on which the glass pane rests with its underside.

Aufgabe der vorliegenden Erfindung ist es daher, eine überfahrbare Bodeneinbauleuchte der eingangs genannten Art bereit zu stellen, die auch bei hoher und hochfrequenter Belastung der Glasscheibe ausreichend gegenüber äußeren Einwirkungen, insbesondere eindringender Feuchtigkeit, abgedichtet ist. Es ist ferner Aufgabe der Erfindung, das bekannte Dichtungssystem überfahrbarer Bodeneinbauleuchten zu verbessern und die Lebensdauer der verwendeten Dichtungen zu erhöhen.Object of the present invention is therefore to provide a drive-over floor light of the type mentioned above, which is sufficiently sealed against external influences, in particular penetrating moisture, even at high and high-frequency loading of the glass. It is a further object of the invention to improve the known sealing system retractable recessed floor lights and to increase the life of the seals used.

Die Aufgabe wird gelöst durch die Merkmale des Anspruchs 1. Demnach liegt dann eine erfindungsgemäße Lösung der Aufgabe vor, wenn die Dichtung zumindest an einem umlaufenden ersten Teilbereich des Randes und/oder an der Oberseite der Glasscheibe im Randbereich angeordnet ist, wobei die Glasscheibe mit der Unterseite an einer Aufnahme des Leuchtengehäuses anliegt, und wobei die Aufnahme im Vergleich zur Dichtung hart ist. Vorzugsweise liegt die Glasscheibe dabei umlaufend formschlüssig an der Aufnahme an. Es wird darauf hingewiesen, dass auch eine partielle Anlage möglich ist. Jedoch sind Lasteinleitung in das Leuchtengehäuse sowie Spannungsverteilung in der Glasscheibe besser bzw. vorteilhafter, wenn eine formschlüssige umlaufende Anlage besteht. Durch die erfindungsgemäße Lösung erfährt die weichelastische Dichtung bei vertikal auf die Oberseite der Glasscheibe gerichteter Lasteinwirkung keinerlei Belastung. Zudem wird die Glasscheibe bei dynamischer Belastung, die senkrecht auf die Oberseite der Glasscheibe gerichtet ist, nicht ständig auf und ab bewegt, da die Aufnahme zumindest im Vergleich zur weichelastischen Dichtung hart und damit starr ist. Die weichelastische Dichtung muss sich demnach bei einer derartigen dynamischen Belastung nicht ständig anpassen und erfährt daher auch keinerlei Verschleiß.The object is achieved by the features of claim 1. Accordingly, a solution according to the invention is the task before, when the seal is disposed at least on a peripheral first portion of the edge and / or on the upper side of the glass in the edge region, wherein the glass with the Bottom of a receptacle of the lamp housing is applied, and wherein the recording is hard compared to the seal. Preferably, the glass sheet is thereby peripherally positively against the recording. It should be noted that a partial investment is possible. However, load introduction is in the luminaire housing and stress distribution in the glass better or more advantageous if a positive circumferential system exists. Due to the solution according to the invention, the soft elastic gasket undergoes no load on vertically directed on the top of the glass pane load. In addition, the glass is under dynamic load, which is directed perpendicular to the top of the glass, not constantly moved up and down, since the recording is hard at least compared to the soft elastic seal and thus rigid. Accordingly, the soft elastic seal does not have to constantly adapt to such a dynamic load and therefore does not experience any wear.

Vorteilhafte Ausgestaltungen der vorliegenden Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the present invention are the subject of the dependent claims.

In einer besonders bevorzugten Ausführungsform liegt die Glasscheibe auch mit einem zweiten Teilbereich des Randes an der Aufnahme an. Bezogen auf die Standardeinbausituation einer überfahrbaren Bodeneinbauleuchte besteht somit auch eine horizontale Anlage zwischen Glasscheibe und starrer Aufnahme. Dadurch ist eine Bewegung der Glasscheibe in horizontaler Richtung ebenfalls ausgeschlossen. Bei den aus dem Stand der Technik bekannten C-förmigen Dichtungen bewegt sich die Glasscheibe aufgrund horizontaler Krafteinwirkung beispielsweise durch Bremsen, Beschleunigen oder Richtungswechsel der über die Bodeneinbauleuchte fahrenden Fahrzeuge membranartig, wodurch Feuchtigkeit in den Leuchteninnenraum gepumpt wird. Bei dieser Art der horizontal auf die Glasscheibe einwirkenden Wechselbelastung ist der Verschleiß der aus dem Stand der Technik bekannten Dichtungen besonders hoch. Durch die Anlage zumindest eines Teilbereichs des Randes der Glasscheibe an der Aufnahme des Leuchtengehäuses wird diese Art der Belastung der Dichtung und der damit einhergehende Verschleiß vermieden. Vorzugsweise ist der Teilbereich des Randes, der an der Aufnahme anliegt, ein an die Unterseite der Glasscheibe angrenzender unterer umlaufender Bereich des Randes. Es sei darauf hingewiesen, dass alternativ auch ein oberer umlaufender Bereich des Randes bzw. ein mittlerer Bereich an der harten Aufnahme anliegen kann, wobei die Dichtung als umlaufende Radialdichtung unten am Rand anliegen kann. Jedoch ist diese konstruktive Möglichkeit aufwendiger in der Realisierung als in dem zuvor erwähnten bevorzugten Fall.In a particularly preferred embodiment, the glass pane also bears against the receptacle with a second partial area of the edge. Related to the standard installation situation of a retractable ground recessed luminaire there is thus also a horizontal installation between the glass pane and the rigid receptacle. As a result, a movement of the glass in the horizontal direction is also excluded. In the known from the prior art C-shaped seals, the glass pane moves due to horizontal force, for example, by braking, accelerating or change direction of moving over the recessed ground vehicle vehicles membrane-like, whereby moisture is pumped into the lamp interior. In this type of horizontal load acting on the glass plate alternating wear of the known from the prior art seals is particularly high. By investing at least a portion of the edge of the glass sheet on the receptacle of the lamp housing this type of loading of the seal and the associated wear is avoided. Preferably, the portion of the edge which bears against the receptacle, a lower peripheral edge of the edge adjacent to the underside of the glass sheet. It should be pointed out that, alternatively, an upper circumferential region of the edge or a central region can rest on the hard receptacle, wherein the seal can abut as a circumferential radial seal at the bottom. However, this constructive possibility is more complicated to implement than in the aforementioned preferred case.

In einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung ist die Aufnahme aus einem Material gefertigt, dessen Elastizitätsmodul über 1000 N/mm2 liegt, wobei die Dichtung aus einem Material besteht, dessen Elastizitätsmodul unter 1000 N/mm2 liegt. Es wird darauf hingewiesen, dass durch die Anlage der Glasscheibe an der Aufnahme des Leuchtengehäuses durch den bevorzugten Formschluss und das jeweils gewählte Material der Aufnahme bereits eine Abdichtung bestehen kann. Die eigentliche Abdichtung wird abschließend jedoch erst durch die weichelastische Dichtung gewährleistet. In jedem Fall ist es wichtig, dass das für die Aufnahme verwendete Material ausreichend hart bzw. steif ist, sodass eine Bewegung der Glasscheibe aufgrund der auf die Glasscheibe wirkenden Lasten ausgeschlossen ist. Dies wird im Regelfall dadurch erreicht, dass der Elastizitätsmodul des für die Aufnahme verwendeten Materials über einem Wert von 1000 N/mm2 liegt. Vorzugsweise ist das Material, aus welchem die Aufnahme gefertigt ist, ein Kunststoff wie beispielsweise Polyamid oder Teflon. Metalle eignen sich ebenfalls sehr gut für die Herstellung der Aufnahmen. Eine schonende Lagerung der Glasscheibe ist z.B. unter Verwendung von Aluminium oder Kupfer möglich.In a further preferred embodiment of the present invention, the receptacle is made of a material whose modulus of elasticity is above 1000 N / mm 2 , wherein the seal consists of a material whose modulus of elasticity is below 1000 N / mm 2 . It It should be noted that by the installation of the glass pane on the receptacle of the lamp housing by the preferred form-fit and the selected material of the recording can already be a seal. The actual sealing is finally ensured only by the soft elastic seal. In any case, it is important that the material used for the recording is sufficiently hard or rigid, so that movement of the glass sheet is excluded due to the loads acting on the glass pane. As a rule, this is achieved by the elasticity modulus of the material used for the absorption being above a value of 1000 N / mm 2 . Preferably, the material from which the receptacle is made, a plastic such as polyamide or Teflon. Metals are also very suitable for making the recordings. A gentle storage of the glass pane is possible, for example, using aluminum or copper.

In einer weiteren besonders bevorzugten Ausführungsform der vorliegenden Erfindung wird die Aufnahme durch einen Aufnahmering gebildet. Ein Aufnahmering kann als separates Bauteil und damit äußerst präzise gefertigt werden, wodurch ein exzellenter Formschluss zwischen Glasscheibe und Aufnahmering besonders kostengünstig und einfach in der Herstellung erreicht werden kann. Der restliche überwiegende Teil des Leuchtengehäuses muss daher nicht zusammen mit der Aufnahme aus einem Material gefertigt werden, wodurch die unterschiedlichen Anforderungen an verschiedene Teile des Leuchtengehäuses erfüllt werden können. Vorzugsweise wird der überwiegende Teil des Leuchtengehäuses aus Edelstahl gefertigt, um das Leuchtengehäuse möglichst robust, langlebig und vor allen Dingen korrosionsbeständig ausführen zu können.In a further particularly preferred embodiment of the present invention, the receptacle is formed by a receiving ring. A receiving ring can be manufactured as a separate component and thus extremely precise, whereby an excellent fit between glass and receiving ring can be achieved particularly cost-effective and easy to manufacture. The remainder of the luminaire housing therefore does not have to be manufactured together with the receptacle made of a material, whereby the different requirements for different parts of the luminaire housing can be met. Preferably, the majority of the lamp housing is made of stainless steel in order to perform the luminaire housing as robust as possible, durable and, above all, corrosion resistant.

In einer weiteren besonders bevorzugten Ausführungsform der vorliegenden Erfindung weist der Rand der Glasscheibe zur Oberseite eine Fase auf, wobei die Dichtung an der Fase anliegt. Dadurch wird auf einfache Art und Weise eine besonders gute und zuverlässige Abdichtung erreicht. Vorzugsweise wird die Dichtung dabei von einem Blendenring gegen die Fase gepresst, der mit dem Leuchtengehäuse verschraubt ist. Eine innere Kontur des Blendenrings verläuft dabei parallel zur Fase, sodass die weichelastische Dichtung bei Montage des Blendenrings sowohl in vertikaler als auch horizontaler Richtung gegen die Fase der Glasscheibe gepresst wird. Auf diese Art und Weise kann die Güte der Abdichtung weiter verbessert werden. Ein weiterer Vorteil wird erreicht, wenn der Blendenring mit der Oberseite der Glasscheibe abschließt. Dadurch können Glasscheibe und Blendenring optimal in die Fahrbahnoberfläche eingepasst werden ohne Unregelmäßigkeiten in der Fahrbahnoberfläche hervorzurufen.In a further particularly preferred embodiment of the present invention, the edge of the glass pane to the top has a chamfer, wherein the seal bears against the chamfer. As a result, a particularly good and reliable sealing is achieved in a simple manner. Preferably, the seal is pressed by a diaphragm ring against the chamfer, which is bolted to the lamp housing. An inner contour of the diaphragm ring runs parallel to the chamfer, so that the soft elastic gasket is pressed during assembly of the diaphragm ring in both the vertical and horizontal direction against the chamfer of the glass. In this way, the quality of the seal can be further improved. Another advantage is achieved when the aperture ring is flush with the top of the glass. This allows glass pane and aperture ring optimally in the road surface are fitted without causing any irregularities in the road surface.

In einer weiteren besonders bevorzugten Ausführungsform der vorliegenden Erfindung ist die Glasscheibe umlaufend kerbfrei präzis geschliffen. Durch die kerbfreie Kontur des Randes wird die Glasscheibe nicht geschwächt und kann gegenüber dem bekannten stufenförmig geschliffenen Glas bei gleicher Lastaufnahme eine erheblich dünnere Materialstärke aufweisen. Dadurch wird eine Kostenersparnis erreicht. Durch den Präzisionsschliff werden zudem eine exzellente formschlüssige Anlage an der Aufnahme erzielt sowie Spannungsspitzen vermieden.In a further particularly preferred embodiment of the present invention, the glass pane is precision-ground without notching. Due to the notch-free contour of the edge, the glass pane is not weakened and may have a considerably thinner material thickness compared to the known stepped ground glass with the same load absorption. Thereby a cost saving is achieved. Precision grinding also achieves an excellent form-locking contact with the receptacle and avoids voltage peaks.

Ein bevorzugtes Ausführungsbeispiel der vorliegenden Erfindung wird im Folgenden anhand von Zeichnungen näher erläutert.A preferred embodiment of the present invention will be explained in more detail below with reference to drawings.

Für die folgenden Ausführungen gilt, dass durch gleiche Bezugszeichen gleiche Teile bezeichnet werden.For the following explanations, the same reference numerals refer to identical parts.

Die in Figur 1 dargestellte erfindungsgemäße Bodeneinbauleuchte 1 besteht im Wesentlichen aus einem Leuchtengehäuse 2, in dem Fassung 14, Leuchtmittel 15 sowie Reflektor 16 angeordnet sind, sowie einer die obere Lichtaustrittsöffnung des Leuchtengehäuses abdeckenden Glasscheibe 5. Das Leuchtengehäuse 2 ist mehrteilig aufgebaut und umfasst den inneren Gehäusetopf 3, dass äußere Gehäuse 4 sowie einen Flansch 18. Innerer Gehäusetopf 3 und äußeres Gehäuse 4 sind zylindrisch ausgeführt und konzentrisch zueinander angeordnet. Diese beiden Hauptbestandteile des Leuchtengehäuses 2 sind vorzugweise aus Edelstahl gefertigt und werden an ihrer Oberseite über den Flansch 18 miteinander verbunden. Der Flansch 18 ist ein separates Bauteil und kann beispielsweise aus Aluminium gefertigt sein. Dargestellt in Figur 1 ist ebenfalls ein Kabeleinlass 17 des inneren Gehäusetopfes, welcher im unteren Bereich nahe der Fassung 14 angeordnet ist. Der Kabeleinlass 17 umfasst ein System zur Abdichtung des inneren Gehäusetopfes 3 gegenüber eindringender Feuchtigkeit.In the FIG. 1 illustrated recessed downlight 1 according to the invention consists essentially of a lamp housing 2, in the socket 14, illuminant 15 and reflector 16 are arranged, as well as a the upper light exit opening of the lamp housing covering glass 5. The luminaire housing 2 is constructed in several parts and comprises the inner housing pot 3, that outer housing 4 and a flange 18. Inner housing pot 3 and outer housing 4 are cylindrical and arranged concentrically with each other. These two main components of the lamp housing 2 are preferably made of stainless steel and are connected to each other at the top via the flange 18. The flange 18 is a separate component and may be made of aluminum, for example. Shown in FIG. 1 is also a cable inlet 17 of the inner housing pot, which is arranged in the lower region near the socket 14. The cable inlet 17 comprises a system for sealing the inner housing pot 3 against moisture penetration.

Die Glasscheibe 5, welche zur Abdeckung der Lichtaustrittsöffnung vorgesehen ist, ist in einem Aufnahmering 12 gelagert, der auf einem umlaufenden Sockel des Flansches 18 aufliegt und in den Flansch 18 eingepasst ist. Die Oberseite der Glasscheibe ist mit dem Bezugszeichen 6, die Unterseite mit dem Bezugszeichen 7 und der Rand mit dem Bezugszeichen 8 beziffert. Der Aufnahmering 12 weist einen L-förmigen Querschnitt auf und liegt mit einem Schenkel an einem unteren Bereich 9 des Randes 8 der Glasscheibe 5 an. Der untere Bereich 9 des Randes 8 kann zylindrisch oder wie dargestellt vorzugsweise leicht konisch nach oben geöffnet ausgeführt sein. Die konische Ausführung erleichtert die Montage und sorgt für einen verbesserten Formschluss zwischen Glasscheibe 5 und Aufnahmering 12. An dem unteren horizontal verlaufenden Schenkel des Aufnahmerings 12 liegt die Glasscheibe 5 mit ihrer Unterseite 7 auf. Zwischen dem Aufnahmering 12 und der Glasscheibe 5 besteht ein präziser Formschluss, der dadurch erreicht wird, dass der Aufnahmering 12 äußerst präzise gefertigt und der Rand 8 der Glasscheibe 5 umlaufend präzis geschliffen wird. Der Aufnahmering 12 ist aus Teflon gefertigt, wobei sich auch andere Kunststoffe wie beispielsweise Polyamid oder Metalle, wie beispielsweise Aluminium oder Kupfer, zur Herstellung des Aufnahmerings 12 eignen. Im Vergleich zu herkömmlichen Bodeneinbauleuchten, bei welchen die Glasscheibe auf einer weichelastischen Dichtung aufliegt bzw. am Rand von dieser weichelastischen Dichtung umschlossen ist, stellt die erfindungsgemäße Lagerung der Glasscheibe in dem Aufnahmering 12 eine starre Lagerung dar. Insbesondere bei der Wahl von Teflon für das Material des Aufnahmerings 12 kann auch bei der erfindungsgemäßen Lösung eine Abdichtung zwischen Glasscheibe 5 und Aufnahmering 12 gegeben sein. Jedoch wird eine sichere Abdichtung abschließend erst durch die über dem Aufnahmering 12 angeordnete Dichtung 11 erzielt. Zwischen dem Aufnahmering 12, der als Teil des Leuchtengehäuses 2 anzusehen ist, und dem ebenfalls dem Leuchtengehäuse 2 zugehörigen Flansch 18 kann eine Presspassung bestehen. Ebenso kann zwischen dem Rand der Glassscheibe und dem Aufnahmering ebenfalls eine leichte Presspassung bestehen. Die weichelastische Dichtung 11 liegt an einer im oberen Bereich des Randes 8 der Glasscheibe 5 ausgebildeten Fase 10 sowie einem oberen Bereich des an dem zylindrischen Bereich 9 des Randes 8 der Glasscheibe 5 anliegenden Schenkel des Aufnahmerings 12 an. Zudem liegt die Dichtung 11 mit ihrer Unterseite auf dem Flansch 18 des inneren Gehäusetopfes 3 auf. Ein radial nach außen geführter Vorsprung 19 des L-förmigen Aufnahmerings 12 greift zudem in eine Nut der Dichtung 11 ein. Diese formschlüssige Nut-Feder-Verbindung zwischen Aufnahmering 12 und Dichtung 11 dient insbesondere als Montagehilfe. Die weichelastische Dichtung 11 wird von einem Blendenring 13, der im fertig montierten Zustand die Glasscheibe 5 ringförmig umschließt und zudem mit der Oberseite 6 der Glasscheibe abschließt, sowohl gegen die Fase 10 des Randes 8 der Glasscheibe 5 als auch gegen eine Oberseite des Flansches 18 gepresst. Der Blendenring 13 wird hierzu mit dem Flansch 18 verschraubt und liegt im fertig montierten Zustand sowohl auf der Dichtung 11 als auch auf einem Vorsprung des Flansches 18 auf. Lasten, die beispielsweise von überrollenden Fahrzeugen auf den Blendenring einwirken, werden somit nicht über die Dichtung 11, sondern über den Flansch 18 in das Leuchtengehäuse 2 der Bodeneinbauleuchte 1 abgeleitet. Ebenso werden auf die Glasscheibe 5 wirkende Lasten über den Aufnahmering 12 und den Flansch 18 und nicht über die Dichtung 11 in das Leuchtengehäuse 2 abgeleitet. Eine Entkopplung der weichelastischen Dichtung 11 von diesen einwirkenden Lasten wird insbesondere dadurch erreicht, dass Dichtung 11 und Aufnahmering 12 zwei separate Bauteile sind. Statt der durch die gezeigte Dichtung 11 erreichten kombinierten Abdichtung zwischen Blendenring 13 und Glasscheibe 5 sowie Flansch 18 wäre für die Abdichtung zwischen Blendenring 13 und Flansch 18 auch eine zusätzliche Dichtung denkbar. Der Blendenring 13 ist vorzugsweise aus einem robusten, verschleißfesten und optisch ansprechenden Material gefertigt. Hierzu eignet sich beispielsweise Edelstahl.The glass sheet 5, which is provided to cover the light exit opening, is mounted in a receiving ring 12 which rests on a peripheral base of the flange 18 and is fitted in the flange 18. The top of the glass sheet is numbered 6, the underside designated by the reference numeral 7 and the edge by the reference numeral 8. The receiving ring 12 has an L-shaped cross section and rests with a leg on a lower portion 9 of the edge 8 of the glass pane 5 at. The lower portion 9 of the rim 8 may be cylindrical or, as shown, preferably slightly tapered upwardly. The conical design facilitates the assembly and ensures an improved positive connection between the glass pane 5 and the receiving ring 12. The glass pane 5 rests with its lower side 7 on the lower, horizontally extending leg of the receiving ring 12. Between the receiving ring 12 and the glass pane 5 there is a precise positive engagement, which is achieved in that the receiving ring 12 made extremely precise and the edge 8 of the glass pane 5 is ground all around precise. The receiving ring 12 is made of Teflon, with other plastics such as polyamide or metals such as aluminum or copper, for making the receiving ring 12 are suitable. Compared to conventional recessed ground luminaires, in which the glass sheet rests on a soft elastic seal or is enclosed at the edge of this soft-elastic seal, the inventive storage of the glass in the receiving ring 12 is a rigid storage. Especially in the choice of Teflon for the material the receiving ring 12 can be given a seal between the glass pane 5 and receiving ring 12 in the inventive solution. However, a secure seal is finally achieved only by the arranged above the receiving ring 12 seal 11. Between the receiving ring 12, which is to be regarded as part of the lamp housing 2, and also the lamp housing 2 associated flange 18 may be an interference fit. Likewise, there may also be a slight interference fit between the edge of the glass sheet and the receiving ring. The soft elastic seal 11 abuts against a chamfer 10 formed in the upper region of the edge 8 of the glass pane 5 and on an upper region of the leg of the receiving ring 12 abutting the cylindrical region 9 of the edge 8 of the glass pane 5. In addition, the seal 11 is located with its underside on the flange 18 of the inner housing pot 3. A radially outwardly led projection 19 of the L-shaped receiving ring 12 also engages in a groove of the seal 11 a. This positive tongue and groove connection between the receiving ring 12 and seal 11 is used in particular as an assembly aid. The soft elastic seal 11 is of a diaphragm ring 13, which in the assembled state, the Glass pane 5 surrounds annular and also ends with the top 6 of the glass, pressed against both the chamfer 10 of the edge 8 of the glass pane 5 and against an upper surface of the flange 18. The diaphragm ring 13 is bolted to the flange 18 and is in the assembled state both on the seal 11 and on a projection of the flange 18. Loads acting on the diaphragm ring, for example, from rolling over vehicles are thus not derived via the seal 11, but via the flange 18 in the lamp housing 2 of the recessed ground light 1. Likewise, loads acting on the glass pane 5 are discharged via the receiving ring 12 and the flange 18 and not via the seal 11 into the lamp housing 2. A decoupling of the soft elastic seal 11 of these acting loads is achieved in particular by the fact that seal 11 and receiving ring 12 are two separate components. Instead of the sealing achieved by the seal 11 shown between diaphragm ring 13 and glass pane 5 and flange 18 would also be an additional seal for the seal between diaphragm ring 13 and flange 18 is conceivable. The aperture ring 13 is preferably made of a robust, wear-resistant and visually appealing material. For example, stainless steel is suitable for this purpose.

Es sei erwähnt, dass sich die erfindungsgemäße Abdichtung nicht nur für die dargestellte Version einer Bodeneinbauleuchte mit kreisrunder Lichtaustrittsöffnung, sondern auch für Bodeneinbauleuchten mit anderer Geometrie, beispielsweise quadratische bzw. rechteckige, und ovale oder längliche Einbauleuchten, eignet. Ferner kann das erfindungsgemäße Dichtungsprinzip bei allen hoch belasteten Leuchten zum Einsatz kommen. Im fertig eingebauten Zustand sind Blendenring 13 sowie Oberseite 6 der Glasscheibe 5 üblicherweise nahtlos in die Fahrbahn bzw. den jeweiligen Bodenbelag eingepasst. Bodenbelag bzw. Fahrbahn sind in den Darstellungen nicht gezeigt.It should be noted that the seal according to the invention is suitable not only for the illustrated version of a recessed floor luminaire with circular light exit opening, but also for recessed floor luminaires with other geometry, such as square or rectangular, and oval or elongated recessed lighting. Furthermore, the sealing principle according to the invention can be used in all highly loaded lights. In the installed state, the aperture ring 13 and the upper side 6 of the glass pane 5 are usually fitted seamlessly into the roadway or the respective floor covering. Flooring or road are not shown in the illustrations.
