- Such a reflector lamp is for example in the European Published Patent Application EP 0 780 884 A1 and EP 0 435 393 A1 described.
- This document discloses a lamp-reflector unit with a metal spring, which is attached to the lamp and rests on the reflector. The lamp is fixed in the reflector with the help of this mechanical spring.
- This reflector lamp is a pin base lamp.
- the metallic holder of the reflector lamp according to the invention is arranged against rotation in the reflector neck and matched to the reflector neck and the base sleeve, that the holder and the base sleeve in the assembly of the reflector lamp by the interaction of the metallic holder with the thread of the base sleeve and with the aid of Fix in the reflector neck depth stop for the metallic holder mutually fix.
- a force in the axial direction is exerted during assembly of the base sleeve on the metallic holder, which tends to reduce the distance between the holder and the bottom of the base sleeve.
- the depth stop prevents axial movement of the holder.
- the base sleeve rests on the outer wall of the reflector neck after being screwed onto the metallic holder.
- the outer wall of the reflector neck forms a stop surface for the base sleeve and thus serves as an abutment to the depth stop on which the metallic holder rests.
- the aforementioned abutment surface for the base sleeve and the aforementioned depth stop for the metallic holder determine the depth of the screw connection.
- the metallic holder provides by its contact with the inner wall of the base sleeve a simple way to make electrical contact with the lamp.
- the torsion-proof arrangement of the metallic holder in the reflector neck is advantageously ensured by the fact that both the shape of the aperture in the reflector neck and the portion of the metallic holder arranged in the aperture of the reflector neck have a shape which is not rotationally symmetrical with respect to the reflector axis, and Dimensions of the aperture and disposed in the opening portion of the metallic holder are coordinated.
- the arranged in the opening of the reflector neck portion of the metallic holder is formed as a sleeve having at least two opposing and mutually parallel side walls, and the reflector neck in the region of its opening at least two mutually opposite inner walls possesses, which abut the parallel side walls of the sleeve.

Description
Die Erfindung betrifft eine Reflektorlampe gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a reflector lamp according to the preamble of patent claim 1.
Eine derartige Reflektorlampe ist beispielsweise in den
Es ist die Aufgabe der Erfindung, eine mit einem Schraubsockel ausgestattete Reflektorlampe bereitzustellen, die mit möglichst einfachen Mitteln eine zuverlässige Halterung und elektrische Kontaktierung der Lampe in dem Reflektor gewährleistet.It is the object of the invention to provide a equipped with a screw reflector lamp, which ensures the simplest possible means a reliable support and electrical contact of the lamp in the reflector.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.This object is achieved by the features of claim 1. Particularly advantageous embodiments of the invention are described in the dependent claims.
Die erfindungsgemäße Reflektorlampe besitzt einen Reflektor, der einen Reflektorhals aufweist und eine Reflektorachse definiert, sowie eine elektrische Lampe, die mittels eines metallischen Halters in dem Reflektorhals fixiert ist, wobei
- ein Abschnitt des metallischen Halters gegen Drehungen um die Reflektorachse gesichert in einem Durchbruch des Reflektorhalses angeordnet ist und durch diesen Durchbruch aus dem Reflektorhals herausragt,
- im Bereich des Reflektorhalses ein Absatz angeordnet ist, der in Richtung der Reflektorachse als Tiefenanschlag für den metallischen Halter ausgebildet ist,
- die Reflektorlampe eine metallische Sockelhülse aufweist, die mit einem Gewinde versehen ist und für die die Außenwand des Reflektorhalses eine Anschlagsfläche bildet, und
- zwischen der Sockelhülse und dem aus dem Reflektorhals herausragenden Teil des in dem Durchbruch des Reflektorhalses angeordneten Abschnitts des metallischen Halters eine Schraubverbindung besteht.
- a portion of the metallic holder is secured against rotation about the reflector axis secured in an opening of the reflector neck and protrudes through this breakthrough from the reflector neck,
- a shoulder is arranged in the region of the reflector neck, which shoulder is designed as a depth stop for the metallic holder in the direction of the reflector axis,
- the reflector lamp has a metallic base sleeve, which is provided with a thread and for which the outer wall of the reflector neck forms a stop surface, and
- there is a screw connection between the base sleeve and the part of the metallic holder projecting from the reflector neck in the section of the metallic holder arranged in the opening of the reflector neck.
Der metallische Halter der erfindungsgemäßen Reflektorlampe ist verdrehsicher in dem Reflektorhals angeordnet und so auf den Reflektorhals und auf die Sockelhülse abgestimmt, dass sich der Halter und die Sockelhülse bei der Montage der Reflektorlampe durch das Zusammenwirken des metallischen Halters mit dem Gewinde der Sockelhülse und mit Hilfe des im Reflektorhals angeordneten Tiefenanschlags für den metallischen Halter gegenseitig fixieren. Durch das Zusammenwirken des metallischen Halters mit dem Gewinde der Sockelhülse wird bei der Montage der Sockelhülse auf den metallischen Halter eine Kraft in axialer Richtung ausgeübt, die bestrebt ist, den Abstand zwischen dem Halter und dem Boden der Sockelhülse zu reduzieren. Der Tiefenanschlag verhindert allerdings eine axiale Bewegung des Halters. Eine gleich große, aber entgegengesetzt wirkende Kraft wird auf die Sockelhülse ausgeübt. Diese Kraft ist ebenfalls bestrebt, den Abstand zwischen dem Boden der Sockelhülse und dem Halter zu verringern. Die Sockelhülse stützt sich nach dem Aufschrauben auf den metallischen Halter an der Außenwand des Reflektorhalses ab. Die Außenwand des Reflektorhalses bildet eine Anschlagsfläche für die Sockelhülse und dient somit als Gegenlager zu dem Tiefenanschlag, auf dem der metallische Halter aufliegt. Insbesondere bestimmen die vorgenannte Anschlagsfläche für die Sockelhülse und der vorgenannte Tiefenanschlag für den metallischen Halter die Tiefe der Schraubverbindung. Dadurch wird eine kittlose Befestigung der Sockelhülse an dem Reflektorhals ermöglicht. Außerdem bietet der metallische Halter durch seinen Kontakt mit der Innenwand der Sockelhülse eine einfache Möglichkeit zur elektrischen Kontaktierung der Lampe.The metallic holder of the reflector lamp according to the invention is arranged against rotation in the reflector neck and matched to the reflector neck and the base sleeve, that the holder and the base sleeve in the assembly of the reflector lamp by the interaction of the metallic holder with the thread of the base sleeve and with the aid of Fix in the reflector neck depth stop for the metallic holder mutually fix. By the interaction of the metallic holder with the thread of the base sleeve, a force in the axial direction is exerted during assembly of the base sleeve on the metallic holder, which tends to reduce the distance between the holder and the bottom of the base sleeve. However, the depth stop prevents axial movement of the holder. An equally large but opposing force is exerted on the base sleeve. This force also tends to reduce the distance between the bottom of the base sleeve and the holder. The base sleeve rests on the outer wall of the reflector neck after being screwed onto the metallic holder. The outer wall of the reflector neck forms a stop surface for the base sleeve and thus serves as an abutment to the depth stop on which the metallic holder rests. In particular, the aforementioned abutment surface for the base sleeve and the aforementioned depth stop for the metallic holder determine the depth of the screw connection. As a result, a cementless attachment of the base sleeve is made possible on the reflector neck. In addition, the metallic holder provides by its contact with the inner wall of the base sleeve a simple way to make electrical contact with the lamp.
Die verdrehsichere Anordnung des metallischen Halters in dem Reflektorhals wird vorteilhafterweise dadurch gewährleistet, dass sowohl die Form des Durchbruchs in dem Reflektorhals als auch der in dem Durchbruch des Reflektorhalses angeordnete Abschnitt des metallischen Halters eine Gestalt besitzen, die bezüglich der Reflektorachse nicht rotationssymmetrisch ist, und die Abmessungen des Durchbruchs und des in dem Durchbruch angeordneten Abschnitts des metallischen Halters aufeinander abgestimmt sind. Auf einfache Weise kann dieses dadurch realisiert werden, dass der in dem Durchbruch des Reflektorhalses angeordnete Abschnitt des metallischen Halters als Hülse ausgebildet ist, die mindestens zwei einander gegenüberliegende und parallel zueinander verlaufende Seitenwände aufweist, und der Reflektorhals im Bereich seines Durchbruchs mindestens zwei einander gegenüberliegende Innenwände besitzt, an denen die parallel verlaufenden Seitenwände der Hülse anliegen. Um den metallischen Halter in dem Reflektorhals zu fixieren, ist er vorteilhafterweise mit mindestens zwei senkrecht zur Reflektorachse abgewinkelten Laschen versehen, die auf dem als Tiefenanschlag ausgebildeten Absatz des Reflektorhalses aufliegen. Der aus dem Reflektorhals herausragende Teil des in dem Durchbruch des Reflektorhalses angeordneten Abschnitts des metallischen Halters ist vorteilhafterweise mit Noppen versehen, die an der Innenwand der Sockelhülse anliegen und in das Gewinde der Sockelhülse greifen. Diese Noppen bilden einen auf das Gewinde der Sockelhülse abgestimmten Gewindegang und ermöglichen dadurch eine Schraubverbindung zwischen der Sockelhülse und dem metallischen Halter. Um eine spielfreie Anordnung der Sockelhülse am Reflektorhals zu gewährleisten, ist die Außenkontur des Reflektorhalses vorteilhafterweise mit einer schräg zur Reflektorachse verlaufenden Fläche versehen. Zusätzlich ist die Sockelhülse vorteilhafterweise mit Hilfe eines Klebemittels oder mittels Crimpen an dem Reflektorhals fixiert, um ein Lösen der Schraubverbindung zwischen der Sockelhülse und dem metallischen Halter zu verhindern. Der metallische Halter wird vorteilhafterweise auch zur elektrischen Kontaktierung verwendet. Zu diesem Zweck ist eine der aus der Lampe herausragenden Stromzuführungen elektrisch leitend mit dem metallischen Halter verbunden. Dadurch wird diese Stromzuführung mit dem Gewinde der Sockelhülse elektrisch kontaktiert, während die andere Stromzuführung mit dem Bodenkontakt der Sockelhülse elektrisch leitend verbunden ist.The torsion-proof arrangement of the metallic holder in the reflector neck is advantageously ensured by the fact that both the shape of the aperture in the reflector neck and the portion of the metallic holder arranged in the aperture of the reflector neck have a shape which is not rotationally symmetrical with respect to the reflector axis, and Dimensions of the aperture and disposed in the opening portion of the metallic holder are coordinated. In a simple way, this can be realized in that the arranged in the opening of the reflector neck portion of the metallic holder is formed as a sleeve having at least two opposing and mutually parallel side walls, and the reflector neck in the region of its opening at least two mutually opposite inner walls possesses, which abut the parallel side walls of the sleeve. In order to fix the metallic holder in the reflector neck, it is advantageously provided with at least two lugs which are angled perpendicular to the reflector axis and rest on the shoulder of the reflector neck designed as a depth stop. The projecting from the reflector neck part of the arranged in the opening of the reflector neck portion of the metallic holder is advantageously provided with nubs, which rest against the inner wall of the base sleeve and engage in the thread of the base sleeve. These nubs form a matched to the thread of the base sleeve thread and thereby allow a screw connection between the base sleeve and the metallic holder. In order to ensure a play-free arrangement of the base sleeve on the reflector neck, the outer contour of the reflector neck is advantageously provided with a plane extending obliquely to the reflector axis. In addition, the base sleeve is advantageously fixed by means of an adhesive or by crimping on the reflector neck to prevent loosening of the screw connection between the base sleeve and the metallic holder. The metallic holder is advantageously also used for electrical contacting. For this purpose, one of the outgoing from the lamp power leads is electrically connected to the metallic holder. As a result, this power supply is electrically contacted with the thread of the base sleeve, while the other power supply is electrically connected to the ground contact of the base sleeve.

Die Figur 1 zeigt eine Seitenansicht des bevorzugten Ausführungsbeispiels der erfindungsgemäßen Reflektorlampe in teilweise geschnittener Darstellung. Diese Reflektorlampe ist zum Betrieb an der Netzspannung vorgesehen und besitzt eine elektrische Leistungsaufnahme von ungefähr 40 Watt. Sie besteht im wesentlichen aus einem Reflektor 10, einer Halogenglühlampe 20, die mittels eines metallischen Halters 30 im Reflektor 10 fixiert ist, und aus einem E14-Schraubsockel zur Spannungsversorgung der Lampe 20. Der E14-Schraubsockel wird von der mit dem Gewinde 41 versehenen metallischen Sockelhülse 40, dem Sockelstein 42 und dem Bodenkontaktplättchen 43 gebildet. Der Reflektor 10 ist rotationssymmetrisch bezüglich seiner Achse A-A ausgebildet und weist eine mittels einer lichtdurchlässigen Scheibe 11 abgedeckte Lichtaustrittsöffnung sowie einen diametral dazu angeordneten Reflektorhals 12 auf. Der Reflektorhals 12 ist hohl und, mit Ausnahme seines Endes, rotationssymmetrisch ausgebildet. Seine Innenwand ist in Richtung des Reflektorhalsendes konisch verjüngt ausgebildet. Die Konizität beträgt 3 Grad gegenüber der Reflektorachse A-A. Der Reflektorhals 12 besitzt an seinem, der Lichtaustrittsöffnung gegenüberliegenden Ende einen von der Rotationssymmetrie abweichenden Durchbruch 14. Dieser Durchbruch 14 wird seitlich durch zwei einander gegenüberliegende, ebene Innenwände 15 und durch zwei einander gegenüberliegende gewölbte Innenwände 16 begrenzt. Durch die Innenwände 15 wird die Öffnung des Reflektorhalses 12 im Bereich des Durchbruches 14 gegenüber dem Hohlraum 13 des rotationssymmetrisch ausgebildeten Teil des Reflektorhalses 12 stufenartig verengt. Die Innenwände 15 bilden daher innerhalb des Reflektorhalses 12 jeweils einen Absatz 17, der als Tiefenanschlag für vier senkrecht zur Reflektorachse A-A abgewinkelte Laschen 31 des metallischen Halters 30 dient. Außerdem sind die beiden Innenwände 15 geringfügig keilförmig ausgebildet, so dass sich der Durchbruch 14 in Richtung des Endes des Reflektorhalses 12 verengt.1 shows a side view of the preferred embodiment of the reflector lamp according to the invention in a partially sectioned illustration. This reflector lamp is intended for operation on the mains voltage and has an electrical power consumption of approximately 40 watts. It consists essentially of a
Die Halogenglühlampe 20 ist axial in dem Reflektor 20 ausgerichtet. Sie wird mittels des metallischen Halters 30 in dem Durchbruch 14 des Reflektorhalses 12 befestigt. Zu diesem Zweck besitzt der einteilig ausgebildete metallische Halter 30 zwei Klammern 32, die den abgedichteten Quetschfuß 21 der Lampe 20 mit Klemmsitz umschließen, und einen als Hülse ausgebildeten Abschnitt 33, der mit Klemmsitz in dem Durchbruch 14 angeordnet ist und teilweise aus dem Ende des Reflektorhalses 12 herausragt. Der als Hülse ausgebildete Abschnitt 33 des metallischen Halters 30 besteht aus zwei einander gegenüberliegenden, parallel zueinander verlaufenden ebenen Seitenwänden 33b und zwei weiteren, einander gegenüberliegenden gewölbten Seitenwänden 33a. Die Hülse 33 hat also in einer Ebene senkrecht zur Reflektorachse A-A einen viereckigen Querschnitt, wobei allerdings die beiden Stirnseiten dieses Vierecks gewölbt sind. Die beiden gewölbten Seitenwände 33a der Hülse 33 sind jeweils mit einer nach außen vorstehenden Noppe 34 ausgestattet, die an der Innenwand der Sockelhülse 40 anliegen und in ihr Gewinde 41 eingreifen. Diese Noppen 34 bilden einen Teil eines Gewindeganges, so dass die Sockelhülse 40 durch eine Schraubverbindung mit der Hülse 33 bzw. mit dem metallischen Halter 30 verbindbar ist. Die beiden ebenen Seitenwände 33b der Hülse 33 liegen an den keilförmig verlaufenden Innenwänden 15 an.The halogen
Aus der Lampe 20 sind zwei Stromzuführungsdrähte 22, 23 herausgeführt, die zur Spannungsversorgung der Glühwendel 24 dienen. Ein erster Stromzuführungsdraht 22 ist mit einer gewölbten Seitenwand der Hülse 33 durch eine Schweißverbindung elektrisch leitend verbunden. Der andere Stromzuführungsdraht 23 ist berührungsfrei bezüglich des metallischen Halters 30 angeordnet und mit dem Bodenkontaktplättchen 43 elektrisch leitend verbunden.From the
Die Sockelhülse 40 ist durch eine Crimpverbindung 44 zusätzlich an dem Ende des Reflektorhalses 12 fixiert, um ein Lösen der Schraubverbindung zwischen dem metallischen Halter 30 und der Sockelhülse 40 zu verhindern. Um eine spielfreie Anordnung der Sockelhülse 40 auf dem Ende des Reflektorhalses 12 zu gewährleisten, ist die Außenkontur des Reflektorhalses 12 mit einer schräg zur Reflektorachse A-A verlaufenden Fläche versehen.
