Definitions
- the present invention relates to a luminaire, in particular a luminaire for illuminating a room in a building.
- luminaires are known in which light sources arranged on a light source carrier are operated with an operating voltage.
- the operating voltage is usually provided by a power supply connected to the electronic ballast, which is disposed within a housing of the lamp and relative to a housing has a corresponding electrical insulation.
- a luminaire which has a luminaire housing, with an end wall and a side wall, the end wall and the side wall forming a housing interior.
- the luminaire furthermore has a luminous means device arranged in the interior of the housing with a luminous means carrier and at least one luminous means arranged on the latter.

- the luminous means device can be operated with an electrical operating voltage, wherein light can be emitted by the at least one luminous means.
- the luminous means device is arranged in the housing interior such that the at least one luminous means is located facing a light exit opening of the luminaire housing.
- the illuminating device is shielded in an electrically insulating manner from the luminaire housing.
- This has the advantage that the distance between the illuminant device and the luminaire housing can be very small, without resulting in a current flow between the illuminant device and housing during operation of the lamp. In this way, a particularly compact construction of the lamp is achieved.
- the luminous means device can thereby also advantageously be operated with high operating voltages.
- the side wall of the lamp housing extends in particular transversely to the end wall and along a lamp longitudinal direction.
- the luminaire housing is generally formed from a metal material and preferably from an aluminum material.
- the insulating component extends at least in sections along the end wall of the lamp housing.

- the fastening parts can be formed for example by screws, rivets, pins or the like.
- the insulating component may in particular be formed from a polybutylene terephthalate material.
- This material has the advantage that it has a high dielectric strength, for example, greater than or equal to 4 kV / mm and at the same time is cost-effective with a vacuum forming process.

- the material may in particular be elastically deformable and has a thermal conductivity of greater than or equal to 1 W / mK and an electrical breakdown strength greater than or equal to 4 kV / mm. Due to the deformability of the material of the heat conduction component, a large contact surface between the heat conduction component and end face and heat conduction component and insulation component or heat conduction component and lighting device is achieved.

Die vorliegende Erfindung betrifft eine Leuchte, insbesondere eine Leuchte zum Beleuchten eines Raumes in einem Gebäude.The present invention relates to a luminaire, in particular a luminaire for illuminating a room in a building.
Aus dem generellen Stand der Technik sind Leuchten bekannt, bei denen auf einem Leuchtmittelträger angeordnete Leuchtmittel mit einer Betriebsspannung betrieben werden. Die Betriebsspannung wird üblicherweise durch ein an das Stromnetz angeschlossenes elektronisches Vorschaltgerät bereitgestellt, das innerhalb eines Gehäuses der Leuchte angeordnet ist und gegenüber einem Gehäuse eine entsprechende elektrische Isolierung aufweist.From the general state of the art luminaires are known in which light sources arranged on a light source carrier are operated with an operating voltage. The operating voltage is usually provided by a power supply connected to the electronic ballast, which is disposed within a housing of the lamp and relative to a housing has a corresponding electrical insulation.
Zum Abtransport von Wärme aus dem Gehäuse ist aus der
Es ist Aufgabe der vorliegenden Erfindung, eine Leuchte bereitzustellen, die einen kompakten Aufbau bei effizienter Wärmeabfuhr aufweist.It is an object of the present invention to provide a luminaire which has a compact construction with efficient heat dissipation.
Diese Aufgabe wird erfindungsgemäß durch eine Leuchte mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a lamp with the features of
Erfindungsgemäß ist eine Leuchte vorgesehen, die ein Leuchtengehäuse, mit einer Stirnwandung und einer Seitenwandung aufweist, wobei die Stirnwandung und die Seitenwandung einen Gehäuseinnenraum ausbilden. Die Leuchte weist weiterhin eine in dem Gehäuseinnenraum angeordnete Leuchtmittelvorrichtung mit einem Leuchtmittelträger und zumindest einem auf diesem angeordneten Leuchtmittel auf. Außerdem weist die Leuchte ein aus einem elektrisch isolierenden Material gebildetes Isolationsbauteil mit einem Hauptabschnitt und einem Einfassungsabschnitt auf, wobei der Hauptabschnitt zwischen der Stirnwandung und der Leuchtmittelvorrichtung angeordnet ist und wobei der Einfassungsabschnitt sich von dem Hauptabschnitt quer zu diesem derart erstreckt, dass der Einfassungsabschnitt zwischen der Leuchtmittelvorrichtung und der Seitenwandung des Leuchtengehäuses angeordnet ist.According to the invention, a luminaire is provided which has a luminaire housing, with an end wall and a side wall, the end wall and the side wall forming a housing interior. The luminaire furthermore has a luminous means device arranged in the interior of the housing with a luminous means carrier and at least one luminous means arranged on the latter. In addition, the lamp has an insulating component formed from an electrically insulating material with a Main portion and a skirt portion, wherein the main portion between the end wall and the illuminant device is arranged and wherein the skirt portion extending from the main portion transversely to this such that the skirt portion between the illuminant device and the side wall of the lamp housing is arranged.
Die Leuchtmittelvorrichtung ist mit einer elektrischen Betriebsspannung betreibbar, wobei Licht durch das zumindest eine Leuchtmittel emittierbar ist. Insbesondere ist die Leuchtmittelvorrichtung derart in dem Gehäuseinnenraum angeordnet, dass das zumindest eine Leuchtmittel einer Lichtaustrittsöffnung des Leuchtengehäuses zugewandt gelegen ist.The luminous means device can be operated with an electrical operating voltage, wherein light can be emitted by the at least one luminous means. In particular, the luminous means device is arranged in the housing interior such that the at least one luminous means is located facing a light exit opening of the luminaire housing.
Durch das Isolationsbauteil wird die Leuchtmittelvorrichtung elektrisch isolierend von dem Leuchtengehäuse abgeschirmt. Dies hat den Vorteil, dass der Abstand zwischen der Leuchtmittelvorrichtung und dem Leuchtengehäuse sehr klein sein kann, ohne dass sich im Betrieb der Leuchte ein Stromfluss zwischen Leuchtmittelvorrichtung und Gehäuse ergibt. Auf diese Weise wird ein besonders kompakter Aufbau der Leuchte erzielt. Insbesondere kann die Leuchtmittelvorrichtung dadurch auch vorteilhaft mit großen Betriebsspannungen betrieben werden.Due to the insulating component, the illuminating device is shielded in an electrically insulating manner from the luminaire housing. This has the advantage that the distance between the illuminant device and the luminaire housing can be very small, without resulting in a current flow between the illuminant device and housing during operation of the lamp. In this way, a particularly compact construction of the lamp is achieved. In particular, the luminous means device can thereby also advantageously be operated with high operating voltages.
Die Seitenwandung des Leuchtengehäuses erstreckt sich insbesondere quer zu der Stirnwandung und entlang einer Leuchtenlängsrichtung. Das Leuchtengehäuse ist allgemein aus einem Metallmaterial und bevorzugt aus einem Aluminiummaterial gebildet.The side wall of the lamp housing extends in particular transversely to the end wall and along a lamp longitudinal direction. The luminaire housing is generally formed from a metal material and preferably from an aluminum material.
Der Hauptabschnitt des Isolationsbauteils ist bevorzugt platten- oder scheibenförmig ausgebildet und erstreckt sich flächig quer zu der Seitenwandung des Leuchtengehäuses bzw. quer zu der Leuchtenlängsrichtung. Insbesondere erstreckt sich das Isolationsbauteil zumindest abschnittsweise entlang der Stirnwandung des Leuchtengehäuses. Der Einfassungsabschnitt des Isolationsbauteils erstreckt sich von dem Hauptabschnitt des Isolationsbauteils aus und quer zu diesem.Der Hauptwand des Leuchtengehäuses bzw. transverse to the lamp's longitudinal direction. In particular, the insulating component extends at least in sections along the end wall of the lamp housing. The skirt portion of the insulating member extends from and transversely of the main portion of the insulating member.
Der Hauptabschnitt des Isolationsbauteils weist eine Ausnehmung auf und die Leuchtmittelvorrichtung ist derart auf dem Hauptabschnitt des Isolationsbauteils angeordnet, dass ein Leuchtmittelbereich des Leuchtmittelträgers, in welchem das zumindest eine Leuchtmittel angeordnet ist, und die Ausnehmung des Hauptabschnitts des Isolationsbauteils zumindest teilweise überlappen. Insbesondere überlappen sich Ausnehmung des Hauptabschnitts des Isolationsbauteils und der Leuchtmittelbereich der Leuchtmittelvorrichtung in Bezug auf eine quer zur Leuchtenlängsrichtung gerichtete radiale Richtung zumindest teilweise oder bereichsweise.The main section of the insulating component has a recess and the illuminating device is arranged on the main section of the insulating component such that a luminous means region of the illuminant carrier, in which the at least one luminous means is arranged, and the recess of the main section of the insulating component at least partially overlap. In particular, the recess of the main section of the insulating component and the illuminant region of the illuminant device overlap at least partially or in sections with respect to a radial direction directed transversely to the luminaire longitudinal direction.
Diese Überlappung von Leuchtmittelbereich und Ausnehmung des Hauptabschnitts hat den Vorteil, dass der Wärmeleitwiderstand zwischen Leuchtengehäuse und Leuchmittelvorrichtung im Bereich der Leuchtmittel verringert ist, sodass eine effiziente Wärmeübertragung von der Leuchtmittelvorrichtung zu dem Leuchtengehäuse erzielt wird.This overlapping of the illuminant area and the recess of the main section has the advantage that the heat-conducting resistance between the luminaire housing and the illuminating device in the area of the illuminant is reduced, so that efficient heat transfer from the illuminant device to the luminaire housing is achieved.
Der Einfassungsabschnitt des Isolationsbauteils weist einen zumindest teilweise gekrümmten Querschnittsverlauf auf.The skirt portion of the insulating member has an at least partially curved cross-sectional shape.
Weiterhin kann vorgesehen sein, dass die Leuchtmittelvorrichtung und das Isolationsbauteil mittels einer Einspannungseinrichtung mit der Stirnwandung des Leuchtengehäuses verbunden sind. Hierzu kann die Einspannungseinrichtung zwischen einer Anbringungsstelle, die an der Seitenwandung des Leuchtengehäuses gelegen ist, und dem Leuchtmittelträger der Leuchtmittelvorrichtung vorgespannt sein. Die Vorspannung der Einspannungseinrichtung kann dadurch erzielt werden, dass diese aus einem elastisch verformbaren Material ausgebildet ist und diese zwischen der Anbringungsstelle und dem Leuchtmittelträger derart eingespannt ist, dass das Material der Einspannungseinrichtung zumindest in einzelnen Bereichen oder Abschnitten elastisch verformt ist. Die Vorspannung kann auch durch Aufbringen einer Andrückkraft, beispielsweise mittels eines Adaperbauteils, das in die Anbringungsstelle einrastet oder eingeschraubt ist aufgebracht werden.Furthermore, it can be provided that the luminous means device and the insulating component are connected by means of a clamping device with the end wall of the lamp housing. For this purpose, the clamping device between an attachment point, which is located on the side wall of the lamp housing, and the Illuminant carrier of the illuminant device to be biased. The bias of the clamping device can be achieved in that it is formed of an elastically deformable material and this is clamped between the mounting location and the light source carrier such that the material of the clamping device is elastically deformed at least in individual areas or sections. The bias can also be applied by applying a pressing force, for example by means of an Adaperbauteils which snaps or screwed into the mounting location.
Alternativ oder zusätzlich zu der Einspannungseinrichtung kann vorgesehen sein, dass die Leuchtmittelvorrichtung und das Isolationsbauteil mittels sich durch den Leuchtmittelträger und den Hauptabschnitt des Isolationsbauteils hindurch erstreckende Befestigungsteile mit der Stirnwandung des Leuchtengehäuses verbunden sind, wobei die Befestigungsteile von einer Isolationshülse eingefasst sind. Die Befestigungsteile können beispielsweise durch Schrauben, Nieten, Stifte oder dergleichen gebildet sein.As an alternative or in addition to the clamping device, provision may be made for the illuminating device and the insulating component to be connected to the end wall of the luminaire housing by means of fixing parts extending through the illuminant carrier and the main section of the insulating component, the fastening parts being enclosed by an insulating sleeve. The fastening parts can be formed for example by screws, rivets, pins or the like.
Das Isolationsbauteil kann insbesondere aus einem Polybutylenterephthalat-Material gebildet sein. Dieses Material hat den Vorteil, dass es eine hohe elektrische Durchschlagfestigkeit, beispielsweise größer oder gleich 4 kV/mm aufweist und gleichzeitig kostengünstig mit einem Vakuumformungsverfahren verarbeitbar ist. Derartige Materialien weisen außerdem eine hohe Hitzeresistenz auf, beispielsweise sind diese bei Temperaturen von mehr als 105 Grad Celsius verwendbar. Auch erfüllen Polybutylenterephthalat-Materialien die Anforderungen an sogenanntes FR-1 ("Flame Retardant 1") Material hinsichtlich Entflammbarkeit und Durchschlagfestigkeit.The insulating component may in particular be formed from a polybutylene terephthalate material. This material has the advantage that it has a high dielectric strength, for example, greater than or equal to 4 kV / mm and at the same time is cost-effective with a vacuum forming process. Such materials also have a high heat resistance, for example, they are usable at temperatures of more than 105 degrees Celsius. Also, polybutylene terephthalate materials meet the requirements of so-called FR-1 ("Flame Retardant 1") material in terms of flammability and dielectric strength.
Weiterhin weist die Leuchte ein Wärmeleitungsbauteil auf, das aus einem elektrisch isolierenden Material gebildet ist und zwischen der Leuchtmittelvorrichtung und dem Isolationsbauteil oder zwischen dem Isolationsbauteil und der Stirnwandung des Leuchtengehäuses angeordnet ist. Falls die Befestigung der Leuchtmittelvorrichtung und des Isolationsbauteils mittels Befestigungsteilen erfolgt, kann vorgesehen sein, dass das Wärmeleitungsbauteil entsprechende Durchgangsbohrungen aufweist, durch welche hindurch sich die Befestigungsteile erstrecken.Furthermore, the luminaire has a heat conduction component which is formed from an electrically insulating material and is arranged between the luminous means device and the insulation component or between the insulation component and the end wall of the luminaire housing. If the fastening of the luminous means device and of the insulating component takes place by means of fastening parts, it can be provided that the heat-conducting component has corresponding through-holes through which the fastening parts extend.
Das Wärmeleitungsbauteil ist vorteilhaft aus einem elektrisch isolierenden Material mit hoher Wärmeleitfähigkeit ausgebildet. Das Material kann insbesondere elastisch verformbar sein und weist eine Wärmeleitfähigkeit von größer oder gleich 1 W/mK und eine elektrische Durchschlagfestigkeit von größer oder gleich 4 kV/mm auf. Durch die Verformbarkeit des Materials des Wärmeleitungsbauteils wird eine große Anlagefläche zwischen Wärmeleitungsbauteil und Stirnfläche und Wärmeleitungsbauteil und Isolationsbauteil oder Wärmeleitungsbauteil und Leuchtmittelvorrichtung erzielt.The heat conduction component is advantageously formed from an electrically insulating material with high thermal conductivity. The material may in particular be elastically deformable and has a thermal conductivity of greater than or equal to 1 W / mK and an electrical breakdown strength greater than or equal to 4 kV / mm. Due to the deformability of the material of the heat conduction component, a large contact surface between the heat conduction component and end face and heat conduction component and insulation component or heat conduction component and lighting device is achieved.
Dadurch wird ein eine effiziente Wärmeabfuhr von der Leuchtmittelvorrichtung zu dem Leuchtengehäuse sichergestellt. Bei einer hohen elektrischen Durchschlagsfestigkeit des Leuchtmittelträgers der Leuchtmittelvorrichtung kann das Wärmeleitungsbauteil auch aus einem Material mit geringerer elektrischer Durchschlagfestigkeit gebildet sein.This ensures an efficient heat dissipation from the illuminant device to the luminaire housing. In the case of a high electrical breakdown strength of the illuminant carrier of the illuminant device, the heat conduction component can also be formed of a material with lower electrical breakdown strength.
Das Wärmeleitungsbauteil kann eine Dicke in einem Bereich zwischen 0,1 mm und 10 mm, bevorzugt zwischen 0,2 mm und 5 mm und insbesondere bevorzugt zwischen 0,3 mm und 3 mm aufweisen. Diese Dicke ergibt sich in einem Zustand, in dem das Wärmeleitungsteil in die Leuchte eingebaut und gegebenenfalls durch das Isolationsteil und die Stirnwandung oder den Leuchtmittelträger und das Isolationsteil oder denThe heat conduction member may have a thickness in a range between 0.1 mm and 10 mm, preferably between 0.2 mm and 5 mm and particularly preferably between 0.3 mm and 3 mm. This thickness results in a state in which the heat conduction member installed in the lamp and optionally through the insulating part and the end wall or the illuminant carrier and the insulating part or the
Leuchtmittelträger und die Stirnwandung zusammengedrückt ist. Dadurch wird einerseits eine Beabstandung der Leuchtmittelvorrichtung von der Stirnwandung des Leuchtengehäuses sichergestellt, wodurch die Gefahr von ungewolltem elektrischem Stromfluss, wie Kriechströmen oder dergleichen, zwischen Leuchtmittelvorrichtung und Gehäuse verringert wird. Gleichzeitig können in diesem Dickenbereich hohe Wärmeströme von der Leuchtmittelvorrichtung an das Leuchtengehäuse übertragen werden.Illuminant carrier and the end wall is compressed. As a result, on the one hand a spacing of the illuminant device is ensured by the end wall of the lamp housing, whereby the risk of unwanted electrical current flow, such as leakage currents or the like, between the illuminant device and the housing is reduced. At the same time high heat fluxes can be transmitted from the lighting device to the lamp housing in this thickness range.
Das zumindest eine Leuchtmittel kann auf dem Leuchtmittelträger derart integriert sein, dass die Leuchtmittelvorrichtung als ein Chip-on-Board LED-Modul, kurz COB-LED-Modul oder als ein PCBA-LED-Modul, kurz für "Printed-Circuit-Board-Assembly-LED-Modul", ausgebildet ist.The at least one light-emitting means can be integrated on the light-emitting means carrier in such a way that the light-emitting device acts as a chip-on-board LED module, COB LED module for short or as a PCBA LED module, short for "printed circuit board". Assembly LED module ", is formed.
Sowohl bei COB-LED-Modulen als auch bei PCBA-LED-Modulen ist der Leuchtmittelträger aus einem Trägersubstrat gebildet, beispielsweise als ein Keramik- oder Aluminiumträger. Bei einem Aluminiumträger ist zusätzlich eine Isolationslage aus einem elektrisch isolierenden Material vorgesehen.Both with COB LED modules and with PCBA LED modules, the light source carrier is formed from a carrier substrate, for example as a ceramic or aluminum carrier. In the case of an aluminum carrier, an insulating layer made of an electrically insulating material is additionally provided.
Bei COB-LED-Modulen sind allgemein ein oder mehrere Leuchtmittel in Form von LED-Elementen direkt auf dem Leuchtmittelträger angeordnet. Die LED-Elemente können zusätzlich mit einer Phosphorschicht bedeckt sein. Bei einem PCBA-LED-Modul sind mehrere LED-Elemente zu jeweils einer LED-Einheit zusammengefasst, die mit dem Leuchtmittelträger verlötet sind.In the case of COB LED modules, one or more light sources in the form of LED elements are generally arranged directly on the light source carrier. The LED elements can additionally be covered with a phosphor layer. In a PCBA LED module several LED elements are combined to form one LED unit, which are soldered to the illuminant carrier.
Dabei kann die Leuchtmittelvorrichtung in einer Draufsicht auf den Leuchtmittelträger beispielsweise rund, rechteckförmig oder polygonförmig ausgebildet sein. Die Leuchtmittel können in geeigneter Weise auf dem Trägersubstrat verteilt angeordnet sein.In this case, the illuminating device can be designed in a plan view of the illuminant carrier, for example, round, rectangular or polygonal. The lighting means can be arranged distributed in a suitable manner on the carrier substrate.
Die Leuchtmittelvorrichtung kann allgemein dazu ausgelegt sein, dass diese mit einer Betriebsspannung von größer oder gleich 90 Volt betreibbar ist. Besonders vorteilhaft ist die Leuchtmittelvorrichtung mit einer Betriebsspannung in einem Bereich zwischen 90 Volt und 380 Volt betreibbar. Dieser Bereich liegt somit oberhalb von Sicherheitskleinspannungen und umfasst insbesondere die Spannungen, die üblicherweise in öffentlichen Stromnetzen als Anschlussspannungen bereitgestellt werden. Dies hat den Vorteil, dass die Leuchtmittelvorrichtung ohne zusätzliches elektronisches Vorschaltgerät, welches die vom Stromnetz bereitgestellte Spannung in eine Betriebsspannung zum Betreiben der Leuchtmittelvorrichtung umwandelt, betrieben werden kann. Auf diese Weise wird der Aufbau der Leuchte insgesamt kompakter.The lighting device may generally be designed so that it can be operated with an operating voltage of greater than or equal to 90 volts. Particularly advantageously, the lighting device can be operated with an operating voltage in a range between 90 volts and 380 volts. This range is therefore above safety extra-low voltages and in particular includes the voltages that are usually provided in public power grids as terminal voltages. This has the advantage that the illuminant device can be operated without additional electronic ballast, which converts the voltage provided by the power supply into an operating voltage for operating the illuminant device. In this way, the overall structure of the lamp is more compact.
Allgemein kann die Leuchtmittelvorrichtung mit einer Gleichspannung und/oder mit einer Wechselspannung betreibbar sein.In general, the luminous means device can be operated with a DC voltage and / or with an AC voltage.

Der Einfassungsabschnitt 32 erstreckt sich somit von dem Hauptabschnitt 31 des Isolationsbauteils 30 quer zu dem Hauptabschnitt 31 derart, dass der Einfassungsabschnitt 32 zwischen der Leuchtmittelvorrichtung 20 und der Seitenwandung 12 des Leuchtengehäuses 10 angeordnet ist.The
Auf diese Weise schirmt der Einfassungsabschnitt 32 die Leuchtmittelvorrichtung 20 in radialer Richtung R1 und der Hauptabschnitt 31 die Leuchtmittelvorrichtung 20 in Leuchtenlängsrichtung L1 gegenüber dem Leuchtengehäuse 10 ab. Da das Isolationsbauteil 30 aus einem elektrisch isolierenden Material gebildet ist, werden möglicherweise zwischen dem Leuchtengehäuse 10 und der Leuchtmittelvorrichtung 20 fließende Kriechströme oder mögliche elektrische Lichtbögen vorteilhaft verhindert. Insbesondere der Einfassungsabschnitt 32 ermöglicht in Bezug auf die radiale Richtung R1 einen geringen Seitenabstand s1 zwischen der Leuchtmittelvorrichtung 20 und der Seitenwandung 12, insbesondere zwischen der Leuchtmittelvorrichtung 20 und der Innenfläche 12a Seitenwandung 12, ohne dass sich ein Stromfluss zwischen Leuchtmittelvorrichtung 20 und Gehäuse 10 ergibt.

Diese überlappende Anordnung von Leuchtmittelbereich 23 und Ausnehmung 33 des Hauptabschnitts 31 hat den Vorteil, dass die Leuchtmittelvorrichtung 20 in dem Bereich der Ausnehmung 33 ungehindert Wärme an die Stirnwandung 11 bzw. ein optional vorgesehenes unten noch im Detail beschriebenes Wärmeleitungsbauteil 40 abgeben kann, beispielsweise durch Strahlung oder Konvektion.This overlapping arrangement of the
Die Ausnehmung 34 kann weiterhin, wie in beispielartig
Das Isolationsbauteil 30 kann insbesondere aus einem Polybutylenterephthalat-Material gebildet sein. Derartige Materialien haben den Vorteil, dass diese kostengünstig sind und eine gute Hitzeresistenz aufweisen, beispielsweise auch bei einer Temperatur von mehr als 105 Grad Celsius noch verwendbar sind.The insulating
Mit dem vorgenannten Material lassen sich Isolationsbauteile 30 beispielsweise in einem Vakuumformverfahren in besonders kostengünstiger Weise aus einem folienartigen Materialzuschnitt herstellen.With the abovementioned material, insulating
Wie bereits im Zusammenhang mit dem Isolationsbauteil 30 beschrieben, weist die Leuchte 1 zusätzlich ein Wärmeleitungsbauteil 40 auf. Das Wärmeleitungsbauteil 40 ist ebenfalls aus einem elektrisch isolierenden Material gebildet. Insbesondere kann das Wärmeleitungsbauteil 40 als ein sich flächig erstreckendes, insbesondere platten- oder scheibenförmiges Bauteil ausgebildet sein.As already described in connection with the
Wie in den
Das Wärmeleitungsbauteil 40 ist vorteilhaft aus einem Material mit hoher Wärmeleitfähigkeit gebildet. Insbesondere kann das Wärmeleitungsbauteil 40 aus einem weichen, insbesondere elastisch verformbaren Material gebildet sein. Weiterhin liegt das Wärmeleitungsbauteil 40 zumindest mit einem Teilbereich einer ersten Kontaktoberfläche 40a an der Stirnoberfläche 11a der Stirnwandung 11 an. Mit zumindest einem Teilbereich einer entgegengesetzt zu der ersten Kontaktoberfläche 40a gelegenen zweiten Kontaktoberfläche 40b kann das Wärmeleitungsbauteil 40, wie in den
Dadurch, dass das Wärmeleitungsbauteil 40 mit zumindest einem Teilbereich der ersten Kontaktoberfläche 40a an der Stirnoberfläche 11a der Stirnwandung 11 anliegt, wird eine zuverlässige und effiziente Wärmeübertragung von der Leuchtmittelvorrichtung 20 an das Leuchtengehäuse 10 sichergestellt.Because the
Das Wärmeleitungsbauteil 40 kann beispielsweise eine Dicke d40, insbesondere eine Querschnittsdicke, in einem Bereich zwischen 0,1 mm und 10 mm, bevorzugt zwischen 0,2 mm und 5 mm und insbesondere bevorzugt zwischen 0,3 mm und 3 mm aufweisen. In diesem Bereich wird eine Beabstandung der Leuchtmittelvorrichtung 20 in Leuchtenlängsrichtung L1 von der Stirnwandung 11 erzielt, bei der einerseits Kriechströme zwischen Leuchtmittelvorrichtung 20 und Leuchtengehäuse 10 zuverlässig verhindert werden. Gleichzeitig weist das Wärmeleitungsbauteils 40 in diesem Dickenbereich einen geringen Wärmeleitungswiderstand auf, wodurch auch eine effiziente Wärmeabfuhr von der Leuchtmittelvorrichtung 20 an das Leuchtengehäuse 10 sichergestellt wird.The

Die Einspannungseinrichtung 2 kann beispielsweise als ein trichterförmiges Bauteil ausgebildet sein, das elastisch verformbare Seitenwandungen 7 aufweist. In diesem Fall kann vorgesehen sein, dass ein erster Endabschnitt 8 der Seitenwandung 7 der Einspannungseinrichtung 2 in eine als Vertiefung der Seitenwandung 12 des Leuchtengehäuses 10 ausgebildete Anbringungsstelle 17 eingreift und ein entgegengesetzt zu dem ersten Endabschnitt 8 gelegener zweiter Endabschnitt 9 der Seitenwandung 7 der Einspannungseinrichtung 2 an einer zweiten Oberfläche 21b des Leuchtmittelträgers 21 anliegt. Eine derartige Variante ist beispielartig in
Die Anbringungsstelle 17 kann auch als eine in radialer Richtung R1 von der der Seitenwandung 12 des Leuchtengehäuses 10 abstehende Erhöhung ausgebildet sein, an deren in Bezug auf die Leuchtenlängsrichtung L1 unteren, der Stirnoberfläche 11a zugewandten Unterseite der erste Endabschnitt 8 der Seitenwandung 7 der Einspannungseinrichtung 2 anliegt.The mounting
Die Anbringungsstelle 17 kann auch durch ein an der Innenoberfläche 12a der Seitenwandung 12 des Leuchtengehäuses 10 ausgebildetes Gewinde ausgebildet sein. In diesem Fall weist der erste Endabschnitt 8 der Einspannungseinrichtung 2 oder ein diesen aufnehmendes Adapterbauteil 53 ein entsprechendes Gegengewinde auf, das in das Gewinde der Seitenwandung 12 einschraubbar ist.The mounting
Die Anbringungsstelle 17 ist allgemein in Bezug auf die Leuchtenlängsrichtung L1 beabstandet zu der Stirnoberfläche 11a gelegen. Insbesondere ist die Anbringungsstelle 17 in Bezug auf die Leuchtenlängsrichtung L1 zwischen der Lichtaustrittsöffnung 16 und einem beabstandet zu dem Hauptabschnitt 31 gelegenen Endabschnitt 35 des Einfassungsabschnitts 32 des Isolationsbauteils 30 gelegen.The
Anstelle eines trichterförmigen Bauteils kann die Einspannungseinrichtung 2 auch durch mehrere elastisch verformbare stabförmige Bauteile ausgebildet sein, die jeweils mit einem ersten Endabschnitt an der Anbringungsstelle 17 angreifen und mit einem entgegengesetzt zu dem ersten Endabschnitt gelegenen zweiter Endabschnitt an der zweiten Oberfläche 21b des Leuchtmittelträgers 21 anliegen.Instead of a funnel-shaped component, the
Weiterhin kann die Einspannungseinrichtung 2 auch als eine Linsenvorrichtung 50 ausgebildet sein, wie dies beispielartig in den
Alternativ oder zusätzlich zu einer Befestigung der im Gehäuseinnenraum 13 angeordneten Komponenten an dem Leuchtengehäuse 10 mittels einer Einspannungseinrichtung 2 kann vorgesehen sein, dass die Leuchtmittelvorrichtung 20 und das Isolationsbauteil mittels sich durch den Leuchtmittelträger 21 und den Hauptabschnitt 31 des Isolationsbauteils 30 - und gegebenenfalls durch das Wärmeleitungsbauteil 40 - hindurch erstreckende Befestigungsteile 3, 4 mit der Stirnwandung 11 des Leuchtengehäuses 10 verbunden sind, wie dies beispielartig in
Die Befestigungsteile 3, 4 weisen generell jeweils einen länglichen Schaft 3A, 4A auf, welcher sich durch entsprechende in dem Leuchtmittelträger 20, dem Isolationsbauteil 30 und gegebenenfalls dem Wärmeübertragungsteil 40 ausgebildete Durchgangslöcher 20A, 20B, 30A, 30B, 40A, 40B hindurch erstreckt und in einer entsprechenden in der Stirnwandung 11 ausgebildeten Befestigungsausnehmung 11A, 11B form- und/oder kraftschlüssig aufgenommen ist. Die Befestigungsteile 3, 4 weisen weiterhin jeweils einen mit dem Schaft 3A, 3B verbundenen Kopf 3B, 4B auf, welcher mit einer infolge der form- und/oder kraftschlüssigen Aufnahme des Schafts 3A, 4A in der Befestigungsausnehmung 11A, 11B gegen die zweite Oberfläche 21b des Leuchtmittelträgers 21 drückt.The
Die Befestigungsteile 3, 4 bewirken einerseits eine Befestigung des Leuchtmittelträgers 20, des Isolationsbauteils 30 und gegebenenfalls des Wärmeübertragungsteils 40 an der Stirnwandung 11. Falls die Leuchte 1 ein Wärmeübertragungsteil 40 aufweist, bewirken die Befestigungsteile 3, 4 auch eine Verformung des Wärmeübertragungsteils 40 und vergrößern damit die Größe der anliegenden Bereiche der Flächen 40a, 40b des Wärmeübertragungsteils 40, was vorteilhaft hinsichtlich der Wärmeabfuhr von der Leuchtmittelvorrichtung 20 an das Leuchtengehäuse 10 ist.On the one hand, the
