Description

Beschreibung description
Leuchte oder Lampe, insbesondere ScheinwerferLuminaire or lamp, in particular headlights
Die Erfindung betrifft eine Leuchte oder Lampe, insbesondere Scheinwerfer einschließlich Unterwasserscheinwerfer, mit einer Aufnahme im Gehäuse zur Befestigung einer Keramikfassung, in die eine Lampenfassung schraubbar oder steckbar ist.The invention relates to a lamp or lamp, in particular headlights including underwater spotlights, with a receptacle in the housing for fastening a ceramic socket into which a lamp socket can be screwed or plugged.
Nach dem Stand der Technik bekannte Lampen besitzen Keramikfas¬ sungen, die mittels einer Schraube befestigt ist, die durch eine Bohrung gesteckt und anschließend in einer Gewindebohrung des Gehäuses festgeschraubt wird. Zur Montage oder Demontage der Keramikfassung sind nachteiligerweise Schraubarbeiten durchzuführen. Darüber hinaus überträgt die Verbindungsschraube jeweils entstehende Wärme auf das meist aus Metall gefertigte Gehäuse.Lamps known from the prior art have ceramic mountings which are fastened by means of a screw which is inserted through a bore and then screwed tightly into a threaded bore in the housing. To assemble or disassemble the ceramic socket, screwing operations are disadvantageously to be carried out. In addition, the connecting screw transfers the heat generated to the housing, which is usually made of metal.
Es ist Aufgabe der vorliegenden Erfindung, bei der eingangs genannten Leuchte oder Lampe die Halterung und Befestigung der Keramikfassung insofern zu verbessern, daß diese leichter mon¬ tiert oder demontiert werden kann und die Gefahr einer Wärme¬ übertragung über das betreffende Verbindungselement minimiert wird.It is an object of the present invention to improve the mounting and fastening of the ceramic socket in the luminaire or lamp mentioned at the outset in such a way that it can be more easily assembled or disassembled and the risk of heat transfer via the connecting element in question is minimized.
Diese Aufgabe wird durch die Merkmalskombination nach Anspruch 1 gelöst. Erfindungsgemäß ist als Befeεtigungsmittel zwischen der genannten Gehäuseaufnahme und der Keramikfassung ein einstückiges Federelement vorgesehen, das aus einem eben gewundenen Ringteil und zwei aus der Ringebene ragenden, abge¬ bogenen Schenkeln besteht. Der Ringteil ist in die Aufnahme des Gehäuses eingelegt oder hiergegen abgestützt oder eingeklemmt, wohingegen die abgebogenen Schenkel in Bohrungen der Keramik¬ fassung eingreifen. Zur Montage einer solchen Leuchte, insbe¬ sondere eines Scheinwerfers, ist es lediglich erforderlich, das Federelement einzulegen bzw. einzuspannen und die Keramikfas¬ sung auf die Schenkel aufzustecken. Muß die Keramikfassung demontiert bzw. ausgetauscht werden, kann sie von dem Federele¬ ment abgezogen bzw. die Austauschfassung wieder aufgesteckt werden, ohne daß weitere Schraubbewegungen erforderlich sind. Da das Federelement nicht mehr wie die Schraube bzw. der Schraubenkopf vollflächig an der Keramikfassung anliegt, son¬ dern nur über kleinere Berührungsflächen, wird der Wärmeüber¬ gang zwischen der Gehäuseaufnahme und der Keramikfassung ent¬ sprechend reduziert. Darüber hinaus können die Keramikfassun¬ gen, die bisher unmittelbar gegen einen Gehäuseteil als Wider¬ lager angelegt bzw. dort aufgeschraubt wurden, so konzipiert werden, daß etwa im Bereich der Keramikfassung entstehende Wärme besser abgeführt werden kann.This object is achieved by the combination of features according to claim 1. According to the invention, a one-piece spring element is provided as the fastening means between said housing receptacle and the ceramic socket, which consists of a flat, coiled ring part and two bent legs protruding from the ring plane. The ring part is inserted into the receptacle of the housing or is supported or clamped against it, whereas the bent legs engage in bores in the ceramic socket. To assemble such a lamp, in particular a headlamp, it is only necessary to insert or clamp the spring element and to attach the ceramic mount to the legs. Must have the ceramic socket disassembled or exchanged, it can be removed from the spring element or the replacement socket can be plugged on again without further screwing movements being required. Since the spring element is no longer in full contact with the ceramic socket like the screw or the screw head, but only over smaller contact surfaces, the heat transfer between the housing receptacle and the ceramic socket is reduced accordingly. In addition, the ceramic frames, which were previously placed directly against a housing part as an abutment or screwed on there, can be designed such that heat generated in the area of the ceramic frame can be better dissipated.
Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Developments of the invention are described in the subclaims.
Vorzugsweise ist das eben gewundene Ringtiel als Ringfeder aus¬ gebildet und stützt sich gegen die Federkraft in der oder gegen die Aufnahme ab. Vorzugsweise besitzt die Aufnahme eine Nut, in der das Ringteil eingelegt oder eingeklemmt ist. Ggf. ist die Ringfeder zur Montage gegen die Federkraft aufzuweiten oder zusammenzudrücken, um das durch die Nut vorgegebene Maß einzu¬ stellen.The just coiled ring shaft is preferably designed as an annular spring and is supported against the spring force in or against the receptacle. The receptacle preferably has a groove in which the ring part is inserted or clamped. Possibly. the ring spring is to be expanded or compressed for assembly against the spring force in order to set the dimension specified by the groove.
Die Schenkel des Federelementes sind nach einer weiteren Ausge¬ staltung der Erfindung federnd gegen die Bohrungswandung der Keramikfassung abgestützt, wobei die Schenkel im unbelasteten Zustand spitzwinklig aus der Ringfederebene abstehen. Bei die¬ ser Ausgestaltung sind die Schenkel vor Aufschieben der Kera¬ mikfassung in die durch die Bohrung in der Keramikfassung gewünschte Position gegen die Federkraft auszurichten.According to a further embodiment of the invention, the legs of the spring element are resiliently supported against the bore wall of the ceramic frame, the legs projecting at an acute angle from the ring spring plane in the unloaded state. In this embodiment, the legs are to be aligned against the spring force before the ceramic socket is slid into the position desired by the bore in the ceramic socket.
Nach einer weiteren Ausgestaltung der Erfindung besitzt die Aufnahme des Gehäuses mehrere im Abstand voneinander angeord¬ nete Widerlager, vorzugsweise Nuten, in bzw. gegen das der Ringteil in unterschiedlichen Höhenlagen einsetzbar bzw. ein- klemmbar ist. Hierdurch können im Gehäuse unterschiedliche Höhenlagen der Keramikfassung je nach verwendeter Reflektoraus¬ bildung eingestellt werden. Ggf. kann die Aufnahme lösbar mit dem Gehäuse verbunden sein, vorzugsweise verschraubt sein.According to a further embodiment of the invention, the receptacle of the housing has a plurality of abutments, preferably grooves, arranged at a distance from one another, in or against that of the Ring part can be used or clamped at different heights. As a result, different heights of the ceramic frame can be set in the housing depending on the reflector design used. Possibly. can the receptacle be detachably connected to the housing, preferably screwed.
Vorzugsweise ist zwischen dem Außenmantel der Keramikfassung und der benachbarten Gehäuseinnenwand ein Ringspalt vorgesehen, so daß zur besseren Wärmeabfuhr entsprechend geeignete Umluft¬ bedingungen geschaffen sind.An annular gap is preferably provided between the outer casing of the ceramic frame and the adjacent inner wall of the housing, so that suitable circulating air conditions are created for better heat dissipation.

Der in Fig. 1 und 2 dargestellte Unterwasserscheinwerfer besitzt ein Gehäuse 1 mit einer oberen Öffnung, in die ein Frontglas 2 eingelegt ist. Das Gehäuse sowie Frontglasrandteile sind nach außen durch eine Blende 3 abgeschirmt. Zur Abdichtung dienen ein O-Ring 4 sowie ein G-Ring 5 in nach dem Stand der Technik bekannter Weise. Unterhalb des Frontglases 2 ist die Reflektorlampe 6 angeordnet, deren elektrische Kontaktverbin¬ dungen in eine Keramikfassung 7 als Halterung gesteckt sind. Die Keramikfassung wird über das erfindungsgemäß verwendete Federelement 8 gegen die Gehäuseinnenwand als Widerlager geklemmt. Zur Stromversorgung dient ein Kabel 9, wobei die ent¬ sprechenden Leitungen über einen Parallelverbinder 10 mit den betreffenden Anschlüssen mit der Keramikfassung verbunden wer¬ den. Der Parallelverbinder 10 ist nach außen über einen Siliconschlauch 11 abgeschirmt. Der Unterwasserscheinwerfer wird im unteren Bereich mittels einer Dichtung 12 und einer äußeren Druckschraube 13 nach unten wasserdicht abgeschirmt. Die zuvor beschriebenen Teile sind in entsprechender Weise in der Explosionszeichnung in Fig. 2 bezeichnet. Zur Aufnahme bzw. zur Klemmung des Federelementes 8 sind in der Gehäuseinnenwand jeweils in höhenversetztem Abstand Nuten 14 eingearbeitet oder eingefräst.The underwater spotlight shown in FIGS. 1 and 2 has a housing 1 with an upper opening into which a front glass 2 is inserted. The housing and front glass edge parts are shielded from the outside by an aperture 3. An O-ring 4 and a G-ring 5 are used for sealing in a manner known from the prior art. The reflector lamp 6 is arranged below the front glass 2, the electrical contact connections of which are inserted into a ceramic socket 7 as a holder. The ceramic socket is clamped against the inner wall of the housing as an abutment via the spring element 8 used according to the invention. A cable 9 is used for the power supply, the corresponding lines being connected to the relevant connections with the ceramic socket via a parallel connector 10. The parallel connector 10 is shielded from the outside by a silicone tube 11. The underwater spotlight is shielded from the bottom in a watertight manner by means of a seal 12 and an external pressure screw 13. The parts described above are correspondingly designated in the exploded view in FIG. 2. To receive or clamp the spring element 8, grooves 14 are machined or milled into the housing inner wall at a spaced-apart distance.
Wie aus Fig. 3 ersichtlich, besitzt die Keramikfassung 7 zwei beabstandete parallele Bohrungen 15, die hier parallel zur Mit¬ telachse der zylinderförmigen Keramikfassung 7 (siehe Fig. 7) ausgeführt sind. Ggf. können auch Sackbohrungen 15 vorgesehen sein. Der Bohrungsdurchmesser, die Bohrungstiefe und die räum¬ liche Ausrichtung der Bohrung 15 sind dem verwendeten Verbin¬ dungselement angepaßt.As can be seen from FIG. 3, the ceramic holder 7 has two spaced parallel bores 15, which here are made parallel to the central axis of the cylindrical ceramic holder 7 (see FIG. 7). Possibly. blind holes 15 can also be provided. The bore diameter, the bore depth and the spatial orientation of the bore 15 are adapted to the connecting element used.
Als Verbindungselement dient das Federelement 8, das aus einem eben gewundenen Ringteil 81 (siehe Fig. 6) und aus der durch dieses Ringteil 81 bestimmten Ringebene schrägwinklig abstehen¬ den Schenkeln 82 besteht. Das Ringteil 81 ist als Ringfeder ausgebildet, die gegen die Federkraft auf einen durch die Nuten 14 bestimmten Durchmesser zusammendrückbar ist. Die Ring¬ feder 81, deren Draufsicht Fig. 6 zu entnehmen ist, besteht aus einem M-förmigen Teil mit einwärtsgezogenen Teilstücken 83, die sich zu den Schenkel 82 fortsetzen. Das Federelement 8 ist ein¬ stückig ausgebildet und besteht aus einem nach dem Stand der Technik bekannten Stahl. Zur Montage der Keramikfassung wird zunächst das Ringfederteil 81 in die Nuten 14 eingeklemmt, anschließend werden die Schenkel 82 in eine im wesentlichen vertikale Lage zur Ringfederebene aufgerichtet, so daß sie in die Bohrungen 15 der Keramikfassung einschiebbar sind. Die Schenkel 82 des Federelementes 8 liegen jeweils an den Wandun¬ gen der Bohrungen 15 gegen die durch die Federwirkung der Schenkel 82 gegebene Federkraft an. Das Federelement 8 ist preiswert herstellbar, leichter handhabbar als die bisher nach dem Stand der Technik verwendete Befestigungsschraube und bie¬ tet geringere Kontaktflächenbereiche zur Keramikfassung, so daß ein Wärmeübergang von der Keramikfassung auf das Gehäuse bzw. Gehäusewiderlager minimiert wird. Da die Keramikfassung 7 nicht mehr unmittelbar am Gehäuse 1 aufliegt, kann im Bodenbereich der Keramikfassung und ringsum im Mantelbereich von der Kera¬ mikfassung abgestrahlte Wärme besser als bisher abgeführt wer¬ den. The spring element 8, which consists of a flat wound ring part 81 (see FIG. 6) and the legs 82 protruding at an oblique angle determined by this ring part 81, serves as the connecting element. The ring part 81 is designed as an annular spring which can be compressed against the spring force to a diameter determined by the grooves 14. The ring spring 81, the top view of which can be seen in FIG. 6, consists of an M-shaped part with inwardly drawn sections 83 which continue to the legs 82. The spring element 8 is formed in one piece and consists of a steel known from the prior art. To assemble the ceramic socket, the ring spring part 81 is first clamped in the grooves 14, then the legs 82 are raised in a substantially vertical position to the ring spring plane, so that they can be inserted into the bores 15 of the ceramic socket. The legs 82 of the spring element 8 each bear against the walls of the bores 15 against the spring force given by the spring action of the legs 82. The spring element 8 is inexpensive to manufacture, easier to handle than the fastening screw previously used according to the prior art, and offers smaller contact surface areas for the ceramic mount, so that heat transfer from the ceramic mount to the housing or housing abutment is minimized. Since the ceramic socket 7 no longer lies directly on the housing 1, heat radiated from the ceramic socket in the base region of the ceramic socket and all around in the jacket region can be dissipated better than hitherto.
