Description

Die Erfindung betrifft eine Lichterkette nach dem Oberbegriff des Anspruchs 1.The invention relates to a light string according to the preamble of claim 1.

Lichterketten sind in unterschiedlichsten Ausführungsformen bekannt.Fairy lights are known in various embodiments.

Bekannt sind Lichterketten, die beispielsweise für die In-Haus-Verwendung geeignet sind. Üblicherweise wird ein aufhängbares Stromkabel verwendet, an welchem in Längsrichtung versetzt liegende Sockel vorgesehen sind, in denen Lampen angeschlossen sind. Die Sockel sind elektrisch mit dem zumindest zweiadrigen Kabel verbunden, so dass eine Lampe mit Strom bei üblicher Netzspannung, üblicherweise 220 V bis 240 V versorgt werden kann. An zumindest einem Ende des Kabels ist ferner ein normaler Stecker angebracht.Known are fairy lights, which are suitable for example for in-house use. Usually, a suspendable power cable is used on which longitudinally offset pedestals are provided, in which lamps are connected. The sockets are electrically connected to the at least two-core cable, so that a lamp can be supplied with current at the usual mains voltage, usually 220 V to 240 V. At least one end of the cable also has a normal plug attached.

Daneben sind beispielsweise auch Lichterketten bekannt geworden, die im Freien eingesetzt werden können, beispielsweise als Lichterketten für Christbäume etc.. Auch aus Sicherheitsgründen sind deshalb derartige Lichterketten mit Netzanschlussgeräten versehen, um beispielsweise Kleinspannungen in der Größe von nur etwa 24 V zu erzeugen.In addition, for example, string lights have become known that can be used outdoors, such as fairy lights for Christmas trees, etc .. Also For safety reasons, therefore, such fairy lights are provided with power supply devices to produce, for example, extra-low voltages in the size of only about 24 volts.

So gilt in der Europäischen Union, dass beispielsweise Lichterketten, die für die Benutzung im Freien geeignet sind, einer entsprechenden Schutzart genügen müssen, beispielsweise der Vorschrift IP44.In the European Union, for example, fairy lights that are suitable for outdoor use must comply with an appropriate degree of protection, for example the IP44 requirement.

In diesem Falle sind die Lichterketten in der Regel nicht mit Glühlampen, sondern mit Leuchtdioden ausgestattet. Dabei werden die verwendeten Glühlampen oder Leuchtdioden in der Regel in einer Reihenschaltung betrieben. Damit beim Durchbrennen einer Lampe nicht die gesamte Beleuchtung ausfällt und die defekte Lampe auch feststellbar und ermittelbar ist, sind bereits Lösungen bekannt geworden, bei denen sich bei jeder Glühlampe im Sockelbereich eine Strombrücke befindet, die den Stromfluss auch bei unterbrochenem Glühfaden sicherstellt.In this case, the fairy lights are usually not equipped with incandescent bulbs, but with LEDs. The incandescent lamps or LEDs used are usually operated in a series circuit. So that the entire lighting does not fail when the lamp is blown through and the defective lamp can also be detected and determined, solutions have already become known in which a current bridge is located in the socket area for each incandescent lamp, which ensures the current flow even when the filament is interrupted.

Eine gattungsbildende Lampenanordnung ist aus der US 6,318,884 B1 bekannt geworden. Gezeigt ist eine Vielzahl von Lampen, die an einem durchgängigen Kabel im Abstand zueinander angeordnet und hierüber mit Strom versorgbar sind. Die Lampen selbst sind als einteilige Lampenanordnungen ausgebildet, die eine kugelförmige Schutzabdeckung umfassen, innerhalb derer die eigentliche lichterzeugende Leuchtstoffröhre angeordnet ist. Die kompakte Einheit aus beiden ist mit einem gemeinsamen Schraubansatz versehen, in welchen die so gebildete einteilige Lampe in den an der durchgängigen Leitung befestigten Lampensockeln eindrehbar ist.A generic type lamp assembly is known from US 6,318,884 B1 known. Shown is a plurality of lamps, which are arranged on a continuous cable at a distance from each other and can be supplied via this power. The lamps themselves are formed as one-piece lamp assemblies comprising a spherical protective cover, within which the actual light-generating fluorescent tube is arranged. The compact unit of both is provided with a common Schraubansatz, in which the thus formed one-piece lamp in the attached to the continuous line lamp sockets can be screwed.

Eine Lampenanordnung ist ferner aus der DE 296 06 527 U1 bekannt geworden. Sie umfasst einen Lampensockel, in welchem eine Glühbirne einsetzbar ist. Die Glühbirne umgebend ist ein Schutzglas in den Lampensockel separat eindrehbar. Die Anschlussleitung umfasst zwei Kabel, die von unterschiedlicher Seite kommend mit dem Kabelende in das Innere des Lampensockels hineingeführt und dort an den entsprechenden Stellen elektrisch angeschlossen sind, um die Lampe mit Energie zu versorgen. Mit anderen Worten ist die elektrische Leitung nicht als durchgängige Leitung gestaltet.A lamp assembly is further from the DE 296 06 527 U1 known. It comprises a lamp base in which a light bulb can be used. Surrounding the bulb is a protective glass in the lamp base screwed separately. The connecting cable comprises two cables which, coming from different sides, are led into the interior of the lamp base with the cable end and are electrically connected there at the corresponding points in order to supply the lamp with energy. In other words, the electrical line is not designed as a continuous line.

Eine Armatur für elektrische Glühlampen ist auch aus der CH 72556 A bekannt geworden. Sie umfasst eine wasserdichte Kappe und einen in diese eingeschraubten Schutzglockenhalter aus Isoliermaterial, der innen das Fassungsgewinde und einen Fassungsstein hält und der mit einem Rand versehen ist, in dem die Schutzglocke eingeschraubt ist. Der eigentliche Glühkörper und die Schutzglocke stellen also getrennte Teile dar, die getrennt in den Lampensockel eingedreht werden können, wobei die Schutzglocke den Lampenkörper umgibt. Wie die Anschlussdrähte angeschlossen sind, kann aus dieser Vorveröffentlichung nicht entnommen werden.A fitting for electric light bulbs is also from the CH 72556 A known. It comprises a waterproof cap and a screwed into this protective bell holder made of insulating material, which holds the socket thread and a socket stone inside and is provided with an edge in which the protective bell is screwed. The actual incandescent body and the protective bell thus represent separate parts that can be screwed separately into the lamp base, wherein the protective bell surrounds the lamp body. How the connection wires are connected, can not be found in this pre-publication.

Eine Lampenanordnung ist schließlich auch aus der US 5,091,836 A bekannt geworden, wobei auch hier von gegenüberliegenden Seiten kommend jeweils ein einadriges Kabel zum Sockel geführt ist, dort endet und dort mechanisch und elektrisch angeschlossen ist, um einen Glühkörper mit Strom zu versorgen.Finally, a lamp arrangement is also made of US 5,091,836 A have become known, and here coming from opposite sides in each case a single-core cable is led to the base, there ends and there is mechanically and electrically connected to supply a filament with electricity.

In einem inneren Zylinderabschnitt kann dabei der Lampenkörper mechanisch eingesetzt und elektrisch angeschlossen werden. In einen diesen umgebenden äußeren Ringansatz kann die eigentliche Schutzabdeckung eingeschraubt werden.In an inner cylinder portion can thereby the lamp body mechanically inserted and electrically connected. In a surrounding outer ring approach the actual protective cover can be screwed.

Demgegenüber ist es Aufgabe der vorliegenden Erfindung, eine nochmals verbesserte, energiesparende und dabei eine hohe Lichtausbeute garantierende Lichterkette zu schaffen, die vor allem auch im Freien eingesetzt werden kann.In contrast, it is an object of the present invention to provide a further improved, energy-saving and thereby a high light output guaranteeing fairy lights, which can be used especially in the open.

Die Aufgabe wird erfindungsgemäß entsprechend den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Im Rahmen der vorliegenden Erfindung wird mit einfachen Mitteln eine nicht nur ästhetisch ansprechende Lösung für eine Lichterkette, sondern auch eine höchst effiziente Lichterkette geschaffen, die vor allem auch im Freien einsetzbar ist und dabei unter Erzeugung einer hohen Helligkeit betrieben werden kann.In the context of the present invention, a not only aesthetically appealing solution for a light string, but also a highly efficient fairy light chain is created by simple means, which is above all also usable outdoors and can be operated while generating a high brightness.

Die erfindungsgemäße Lichterkette ist so aufgebaut, dass als Leuchtmittel nicht übliche Glühlampen oder Leuchtdioden verwendet werden, sondern sogenannte Energiesparlampen, d.h. Kompaktleuchtstoff-Lampen. Derartige Kompaktleuchtstoff-Lampen sind an sich für den Außenbereich ungeeignet und dürfen im Freien nicht eingesetzt werden.The fairy light chain according to the invention is constructed in such a way that incandescent lamps or light-emitting diodes which are not customary are used as the light source, but so-called energy-saving lamps, i. Compact fluorescent lamps. Such compact fluorescent lamps are in themselves unsuitable for outdoor use and must not be used outdoors.

Hier schlägt die Erfindung vor, dass die Leuchtstoff-Lampen in geschirmten Sockeln sitzen, wobei die Sockel mit einer die Leuchtstoff-Lampe aufnehmenden licht- oder zumindest teillichtdurchlässigen Schutzumhüllung versehen sind. Diese Schutzumhüllung kann im Extremfall mit dem Energiesockel einstückig ausgebildet, beispielsweise verschweißt sein. Bevorzugt wird jedoch eine Schraub- oder Bajonettverbindung oder sonstige geeignete lösbare Verbindungen zwischen der Lampenabdeckung und dem Lampensockel, um die unterhalb der Lampen-Schutzabdeckung befindliche Kompaktleuchtstoff-Lampe spritzwassergeschützt unterzubringen. Bevorzugt kann dies durch einen oder mehrere Dichtringe realisiert werden, die beispielsweise an einem Schraubansatz der Lampenschutzabdeckung vorgesehen sind und/oder an einem Dichtring, der im Bereich eines überwurfmutterartigen Aufnahmebereichs für den Gewindeabschnitt der Lampenschutzabdeckung einlegbar ist.Here, the invention proposes that the fluorescent lamps sit in shielded sockets, wherein the pedestals are provided with a light-emitting or at least partially leak-proof protective covering accommodating the fluorescent lamp. This protective covering can in extreme cases with the Energy socket integrally formed, for example, be welded. However, preference is given to a screw or bayonet connection or other suitable releasable connections between the lamp cover and the lamp cap, to accommodate the compact fluorescent lamp located underneath the lamp protective cover splash-proof. This can preferably be realized by one or more sealing rings which are provided, for example, on a screw neck of the lamp protection cover and / or on a sealing ring which can be inserted in the region of a union nut-like receiving region for the threaded portion of the lamp protection cover.

In Figur 1 ist in schematischer Darstellung ein Ausführungsbeispiel für eine erfindungsgemäße Lichterkette dargestellt, und zwar mit einem zumindest zweiadrigen Kabel 3, an dessen einem Kabelende 3a ein üblicher Netzstecker 5 elektrisch angeschlossen ist. Über den Netzstecker 5 kann die Lichterkette bei üblicher Netzspannung von beispielsweise 220 V bis 240 V betrieben werden. Ebenso kann die Lichterkette auch in anderen Ländern bei anderen Netzspannungen betrieben werden, beispielsweise bei Netzwechselspannungen zwischen 110 V und 120 V etc.In FIG. 1 is shown in a schematic representation of an embodiment of a fairy light chain according to the invention, with an at least two-core cable 3, at one end of the cable 3a a conventional power plug 5 is electrically connected. About the power plug 5, the lights can be operated at a common mains voltage, for example, 220 V to 240 V. Likewise, the fairy lights can be operated in other countries at other mains voltages, for example, AC mains voltages between 110 V and 120 V, etc.

In Längsrichtung des Kabels 3 versetzt zueinander sind Lampensockel 7 vorgesehen, deren Außenwandung mit dem Material des Kabels 3 bevorzugt fest verschweißt, verpresst etc. ist, so dass der Lampensockel 7 im Bereich des Kabels 3 wasserdicht ist.Offset from one another in the longitudinal direction of the cable 3, lamp sockets 7 are provided, the outer wall of which is preferably firmly welded, pressed, etc., to the material of the cable 3, so that the lamp base 7 is watertight in the region of the cable 3.

Im Rahmen des Lampensockels 7 läuft das zumindest zweiadrige Kabel 3 zu einer nächsten Lampenanordnung 9 weiter. Mit anderen Worten besteht also das Kabel 3 nicht aus einzelnen Kabelabschnitten, die jeweils in einem Lampensockel enden und dort elektrisch und mechanisch angeschlossen sind, sondern aus einer durchgehenden Kabelanordnung, bei der innerhalb eines jeden Lampenssockels die entsprechenden Kabel quasi "angezapft" werden, um eine Lampe mit Energie zu versorgen. Gleichzeitig wird also innerhalb eines Lampensockels 7 für die zumindest beiden Leitungen des Kabels 3 eine elektrische Verbindung zu einer in den Lampensockel 7 integrierten Lampenfassung 11 (Figur 2) gewährleistet. Im gezeigten Ausführungsbeispiel sollen Energiesparlampen 13 in Form sogenannter Kompaktleuchtstoff-Lampen 13a verwendet werden. Üblicherweise sind derartige Kompaktleuchtstoff-Lampen mit einem Gewindesockel, beispielsweise einer Fassung gemäß Standard E27 versehen. Ebenso könnte der Lampensockel 7 aber auch mit einer steckbaren Lampenfassung 15 versehen sein, die mit ihrem Steckansatz in eine entsprechende Steckaufnahme im Sockel 7 der Lampenhaltung einsteckbar ist.As part of the lamp cap 7, the at least two-core cable 3 continues to a next lamp assembly 9 on. In other words, therefore, the cable 3 does not consist of individual cable sections, each ending in a lamp base and are connected there electrically and mechanically, but from a continuous cable arrangement, in which the corresponding cables are quasi "tapped" within each lamp socket to a To supply the lamp with energy. At the same time, therefore, within a lamp base 7 for the at least two lines of the cable 3, an electrical connection to an integrated lamp socket 7 in the lamp socket 11 (FIG. FIG. 2 ) guaranteed. In the illustrated embodiment, energy-saving lamps 13 are to be used in the form of so-called compact fluorescent lamps 13a. Usually, such compact fluorescent lamps are provided with a threaded socket, for example a socket according to standard E27. Likewise, the lamp base 7 could also be provided with a plug-in lamp socket 15, with its plug-in approach in a corresponding socket in the socket 7 of the lamp holder is inserted.

Wie in dem gezeigten Ausführungsbeispiel auch angedeutet ist, umfasst der jeweilige Lampensockel 7 eine wasserdicht ausgebildete Lampenaufnahme 17, im gezeigten Ausführungsbeispiel mit einem Innengewinde, da die entsprechenden anzuschließenden Lampen wie erwähnt mit einem mit Außengewinde versehenen Lampensockel 11 ausgestattet sind.As also indicated in the exemplary embodiment shown, the respective lamp base 7 comprises a watertightly formed lamp receptacle 17, in the embodiment shown with an internal thread, since the corresponding lamps to be connected are equipped, as mentioned, with an externally threaded lamp base 11.

Gemäß der Darstellung gemäß Figur 2 ist auch zu ersehen, dass ferner eine entsprechend groß dimensionierte Lampenabdeckung 19 vorgesehen ist, die nachfolgend teilweise auch als Kunststoffabdeckung 19a bezeichnet wird. Sie besteht entweder aus klarem Kunststoff, ist also möglichst vollständig lichtdurchlässig. Möglich ist aber auch die Verwendung von eingefärbten Lampenabdeckungen, die somit nur teillichtdurchlässig sind und bestimmte Farbwirkungen erzeugen können.As shown in FIG FIG. 2 It can also be seen that, in addition, a correspondingly large-dimensioned lamp cover 19 is provided, which is also sometimes referred to below as a plastic cover 19a. It consists either of clear plastic, so it is as completely translucent as possible. However, it is also possible to use colored lamp covers, which are therefore only partially translucent and can produce certain color effects.

Im gezeigten Ausführungsbeispiel ist die Lampenabdeckung 19 kolben- oder kugelförmig gestaltet und weist eine Einführöffnung 19b auf, mit der die Lampenabdeckung 19 mit ihrem mit einem Außengewinde 19c versehenen Schraubansatz 19d in das Innengewinde 117a des nach Art einer Gewindeaufnahme gestalteten Haltesockels 117 des Lampensockels 7 eindrehbar ist. Mit anderen Worten ist der als Zylindertopf (nämlich als doppelwandiger Zylindertopf mit zentraler Durchtrittsöffnung, worauf nachfolgend noch eingegangen wird) gestaltete Haltesockel 117 konzentrisch zu der dem Lampensockel 7 in entsprechender Länge zentrisch und axial durchsetzenden Lampenaufnahme 17 zur Aufnahme und zum Anschluss einer Energiesparlampe 13 ausgebildet, wobei in die im Lampensockel 7 axial verlaufende Lampenaufnahme 17 der Lampensockel 11 der Kompaktleuchtstoff-Lampe 13 eingedreht wird, wohingegen in das Innengewinde 117a des außen liegenden Teils des Haltesockels 117, das Außengewinde 19c des Schraubansatzes 19d der Lampenabdeckung 19 eingedreht wird.In the illustrated embodiment, the lamp cover 19 is designed piston or spherical and has an insertion 19b, with the lamp cover 19 is screwed with its provided with an external thread 19c screw 19d in the internal thread 117a of the manner of a threaded receiving support base 117 of the lamp cap 7 , In other words, as a cylinder pot (namely as a double-walled cylinder pot with central passage opening, which will be discussed below) designed support base 117 concentric with the lamp base 7 in a corresponding length centric and axially interspersed lamp receptacle 17 for receiving and connecting an energy saving lamp 13 is formed wherein in the lamp socket 7 axially extending lamp holder 17 of the lamp base 11 of the compact fluorescent lamp 13 is screwed, whereas in the internal thread 117 a of the outer part of the support base 117, the external thread 19 c of the screw 19 d of the lamp cover 19 is screwed.

Um eine wasserdichte oder zumindest spritzwassergeschützte Anordnung zu realisieren, ist die Lampenabdeckung 19 von ihrer Einführöffnung 19b versetzt liegend am gegenüberliegenden Endbereich des Außengewindes 19c (also am Übergang zu dem kolbenförmigen Abschnitt der Lampenabdeckung 19) mit einem umlaufenden Dichtring 27 versehen, der problemlos aufgeschoben und in diese Position gebracht werden kann. Durch die kolbenartige Durchmessererweiterung der Lampenabdeckung wird ein lampenabdeckungsseitiger Anschlagsring 19f als Gegenanschlag für den Dichtring 27 gebildet. Bei Gebrauch kann die Lampenabdeckung 19 über die zuvor eingeschraubte oder eingesteckte Kompaktleuchtstoff-Lampe 13a übergeschoben und mit ihrem Außengewinde 19c in das Innengewinde 117a des Haltesockels 117 des Lampensockels 7 eingedreht werden. Dabei kann die Lampenabdeckung 19 soweit eingedreht werden, bis der entsprechende Dichtring 27 mit dem am freien Ende befindlichen Rand 117d des Haltesockels 117 zusammenwirkt und dort zwischen dem Stirnrand 117d des Haltesockels 117 und dem durch die Kolbenerweiterung gebildeten Anschlagring 19f der Lampenabdeckung verpresst wird. Dadurch wird eine wasserdichte, d.h. spritzwasserdichte Verbindung zwischen der Lampenabdeckung und dem Lampensockel 7 geschaffen.In order to realize a waterproof or at least splash-proof arrangement, the lamp cover 19 is offset from its insertion opening 19b lying at the opposite end of the external thread 19c (ie at the transition to the piston-shaped portion of the lamp cover 19) provided with a circumferential sealing ring 27 which slid easily and in this position can be brought. Due to the piston-like diameter extension of the lamp cover, a lamp cover-side stop ring 19f is formed as a counter stop for the sealing ring 27. In use, the lamp cover 19 can be pushed over the previously screwed or plugged compact fluorescent lamp 13a and screwed with its external thread 19c in the internal thread 117a of the support base 117 of the lamp cap 7. In this case, the lamp cover 19 can be screwed in until the corresponding sealing ring 27 cooperates with the edge 117d of the retaining base 117 located at the free end and is compressed there between the end edge 117d of the retaining base 117 and the stop ring 19f of the lamp cover formed by the piston enlargement. This will produce a watertight, i. splash-tight connection between the lamp cover and the lamp base 7 created.

Alternativ oder ergänzend kann auch im Inneren oder im Boden der topfförmigen Ringnut 117b des Haltesockels 117 ein Dichtring vorgesehen sein, auf welchem der untere stirnseitige Rand 19e der Lampenabdeckung 19 beim Eindrehen in den Haltesockel 117 aufläuft und dort einen nicht näher gezeigten Dichtring 29 verpresst, um alternativ oder ergänzend auch hier eine Dichtung vorzusehen. Wasser oder Spritzwasser kann somit von außen nicht zu den stromführenden Teilen der Lampenfassung bzw. der Lampensockel-Fassung gelangen.Alternatively or additionally, 117 may be provided in the interior or in the bottom of the cup-shaped annular groove 117b of the support base 117, a sealing ring on which the lower end-side Edge 19e of the lamp cover 19 runs when screwing into the support base 117 and there pressed a not-shown sealing ring 29, to provide alternatively or additionally here a seal. Water or splash water can thus not reach from the outside to the live parts of the lamp socket or lamp socket version.

Nachfolgend wird noch auf Figur 3 Bezug genommen, in der der erfindungsgemäße Aufbau der Lampenhalterung gezeigt wird.Below will be on FIG. 3 Reference is made, in which the construction of the lamp holder according to the invention is shown.

Aus dieser schematischen Längsschnittdarstellung ist zu entnehmen, dass der Lampensockel 7 aus zwei Sockel-Basisabschnitten besteht, nämlich aus einem zur Lampenabdeckung 19 entfernt liegenden ersten Lampensockel-Basisabschnitt 7a und aus einem Lampensockel-Anschlussabschnitt 7b, wobei der Lampensockel 7 neben diesen beiden Abschnitten 7a und 7b ferner noch den erwähnten Haltesockel oder Haltesockelabschnitt 117 umfasst, auf den nachfolgend eingegangen wird. Der Lampensockel-Basisabschnitt 7a und der Lampensockel-Anschlussabschnitt 7b sind unter sandwichartiger Aufnahme des bevorzugt gummiummantelten zwei- oder beispielsweise dreiadrigen Kabels 3 (Flachkabels 3) miteinander fest verbunden, im gezeigten Ausführungsfall unter Verwendung einer Befestigungsschraube 6 fest miteinander verbunden. Diese Befestigungsschraube 6 wird bei der Montage von der Innenseite des Lampensockel-Anschlussabschnittes 7b aus in eine im Bodenbereich vorgesehene Öffnung eingedreht, und zwar durch das Lampenkabel 3 hindurch bis in eine entsprechende Bohrung (Sackbohrung) in dem zu äußerst liegenden Lampensockel-Basisabschnitt 7a.From this schematic longitudinal sectional view it can be seen that the lamp cap 7 consists of two base base sections, namely a lamp base 19 remote to the first lamp base base portion 7a and a lamp base terminal portion 7b, the lamp cap 7 in addition to these two sections 7a and 7b further includes the mentioned holding base or holding base portion 117, which will be discussed below. The lamp base base portion 7a and the lamp base terminal portion 7b are fixedly connected to each other by sandwiching the rubber-sheathed two- or, for example, three-wire cable 3 (flat cable 3), in the embodiment shown firmly connected to each other using a fastening screw 6. This mounting screw 6 is screwed during assembly from the inside of the lamp base connection portion 7b in an opening provided in the bottom area, through the lamp cable 3 through into a corresponding hole (blind hole) in the lying too far lamp base base portion 7a.

In den beiden Lampensockelabschnitten 7a, 7b ist zum einen eine entsprechende Ausnehmungsnut 55 bzw. eine Ausbuchtung 66 vorgesehen, die letztlich dazu dienen, dass das mit den Stromkabeln versehene, als Flachkabel ausgebildete elektrische Anschlusskabel 3 korrosionsfrei zwischen den beiden Sockelabschnitten 7a, 7b eingebaut werden kann.In the two lamp base sections 7a, 7b, on the one hand, a corresponding recess groove 55 or a bulge 66 is provided, which ultimately serve that the electrical connection cable 3 provided with the power cables and designed as a flat cable can be installed between the two base sections 7a, 7b in a corrosion-free manner ,

Dabei umfasst der Lampensockel-Anschlussabschnitt 7b entsprechende Kontaktierungseinrichtungen, wodurch eine elektrisch leitende Verbindung mit den beiden Polen des zumindest zweiadrigen Kabels bewerkstelligt wird, nämlich mit einer nicht näher gezeigten Zunge, die mit dem Fußpunkt der eingedrehten Energiesparlampe 13 in Kontakt tritt, und mit einer elektrisch leitfähigen Innengewindeanordnung 17', die an der Innenseite des Lampensockel-Anschlussabschnittes 7b ausgebildet ist.In this case, the lamp base connection portion 7b comprises corresponding contacting means, whereby an electrically conductive connection is accomplished with the two poles of the at least two-core cable, namely with a tongue not shown in detail, which comes into contact with the base of the screwed energy saving lamp 13, and with an electric conductive female thread assembly 17 'formed on the inner side of the lamp base terminal portion 7b.

Im gezeigten Ausführungsbeispiel wird die Öffnungs- und Anschlussseite 17a des Lampensockel-Anschlussabschnittes 7b dann in den bereits erwähnten Haltesockel 117 eingesteckt, und zwar unter sandwichartiger Zwischenschaltung einer wasserdichten, bevorzugt gummielastischen Dichtmuffe oder Dichtzylinderanordnung 127.In the exemplary embodiment shown, the opening and connection side 17a of the lamp base connection section 7b is then inserted into the already mentioned support base 117, specifically under a sandwich-like interposition of a watertight, preferably rubber-elastic sealing sleeve or sealing cylinder arrangement 127.

Wie aus der axialen Querschnitts-Explosionsdarstellung gemäß Figur 3 zu ersehen ist, weist der Haltesockel 117 auf der Lampensockel-Anschlussseite einen innenliegenden Doppelwandabschnitt auf, und zwar unter Ausbildung der erwähnten umlaufenden Ringnut 117b, in der letztlich das Außengewinde 19c der Lampenabdeckung 19 zu liegen kommt. Der Haltesockel 117 mit seinem Doppelwandabschnitt umfasst also einen außenliegenden Wandabschnitt 118a und einen dazu innenliegenden zylinderförmigen Wandabschnitt 118a, 118c, die im Bereich des Bodens der Ringnut 117b über einen Wandabschnitt 118b (Boden 118b) miteinander verbunden sind. An dem Inneren der beiden konzentrisch zueinander liegenden Wandabschnitte 118a, 118c schließt sich in Richtung Lampenabdeckung 19 ein nach innen vorstehender Ring- oder Flanschansatz 118d an, auf den nachfolgend noch eingegangen wird. Da der Lampensockel-Anschlussabschnitt 7b an seiner Öffnungs-Steckseite 17a noch mit einem radial nach außen vorstehenden Halte- oder Schnappring 7d versehen ist, der beim Einstecken in den Haltesockel 117 an einem oder mehreren, gegebenenfalls auch umlaufenden und radial nach innen vorstehenden Steckvorsprüngen 117c diesen hintergreifend einschnappt, ist dadurch die Gesamtanordnung mit dem Lampensockel-Anschlussabschnitt 7b (der gleichzeitig auch die Lampenaufnahme 17 mit dem dort vorgesehenen Innengewinde zum mechanischen oder elektrischen Anschluss einer Lampe 13, 13a umfasst) und dem Haltesockel 117 als feste, insgesamt nach außen hin wasserdicht geschirmte Einheit verwendbar, in die dann die erwähnte Energiesparlampe 13a je nach Anschlussverbindung und Lampentyp eingesteckt oder eingedreht werden kann.As is apparent from the axial cross-sectional exploded view according to FIG. 3 can be seen, the support base 117 on the lamp socket connection side an inner double wall portion, namely to form the aforementioned circumferential annular groove 117 b, in the end, the external thread 19c of the lamp cover 19 comes to rest. The holding base 117 with its double wall section thus comprises an outer wall section 118a and a cylindrical wall section 118a lying on the inner side, 118c, which are connected to each other in the region of the bottom of the annular groove 117b via a wall section 118b (bottom 118b). At the interior of the two concentric wall sections 118a, 118c, in the direction of the lamp cover 19, an inwardly projecting ring or flange projection 118d follows, to which reference will be made below. Since the lamp socket connection portion 7b is still provided at its opening plug side 17a with a radially outwardly projecting holding or snap ring 7d, which when plugged into the support base 117 at one or more, possibly also circumferential and radially inwardly projecting plug projections 117c this engages behind the snap, this is the overall arrangement with the lamp base connection portion 7b (which also includes the lamp holder 17 with the internal thread provided there for mechanical or electrical connection of a lamp 13, 13a) and the support base 117 as a solid, waterproof shielded to the outside Unit used, in which then the mentioned energy-saving lamp 13a can be inserted or screwed in depending on the connection connection and lamp type.

Auch die erwähnte Dichtmuffe oder Dichtzylinderanordnung 127 weist einen Stufenabsatz oder einen stufenförmigen Zwischenabsatz 127c auf, in welchem die Dichtmuffe oder Dichtzylinderanordnung 127 von einem Zylinderabschnitt 127a mit größerem Durchmesser in einen Zylinderabschnitt mit kleinerem Durchmesser (in Richtung Lampenabdeckung 19) übergeht. Im montierten Zustand liegt dieser Stufenabsatz 127c auf dem ringförmigen nach innen vorstehenden Ansatz 118d des doppelwandigen Haltesockels 117 auf, wobei der zylinderförmige Abschnitt 127a der Dichtmuffe oder Dichtzylinderanordnung 127 mit größerem Durchmesser an dem inneren zylinderförmigen Wandabschnitt 118c des Haltesockel 117 anliegt und ein ringförmig vorstehender Zylinderansatz 7e an der Innenseite der Dichtmuffe oder Dichtzylinderanordnung 127 in dem Bereich seines Abschnittes 127a mit größerem Durchmesser anliegt, so dass zwischen diesem Ringansatz 7e des Lampensockel-Anschlussabschnittes 7b und der inneren zylinderförmigen Wandung 118c des Haltesockels 117 der entsprechende Abschnitt 127a der Dichtmuffe oder Dichtzylinderanordnung 127 (vorzugsweise leicht verpresst oder unter Spannung stehend) sandwichtartig gehalten ist, um hier eine wasserdichte Verbindung zwischen den Lampensockel-Anschlussabschnitt 7b und den Haltesockel 117 zu gewährleisten. Durch die offenen Zentralabschnitte kann dann die Leuchtstofflampe mit ihrem Anschlussende in den Lampensockel eingesteckt und elektrisch angeschlossen und darüber gehalten werden, wobei dann abschließend die Schutzabdeckung 19 aufgedreht wird.The mentioned sealing sleeve or sealing cylinder arrangement 127 also has a stepped shoulder or step-like intermediate shoulder 127c, in which the sealing sleeve or sealing cylinder arrangement 127 passes from a cylinder section 127a of larger diameter into a cylinder section of smaller diameter (in the direction of the lamp cover 19). When assembled, this stepped shoulder 127c rests on the annular inwardly projecting lug 118d of the double-walled retaining base 117, with the cylindrical portion 127a of the larger diameter sealing sleeve or sealing cylinder assembly 127 on the inner cylindrical wall portion 118c of the support base 117 abuts and an annular projecting cylinder shoulder 7e on the inside of the sealing sleeve or sealing cylinder assembly 127 in the region of its portion 127a of larger diameter is applied, so that between this annular shoulder 7e of the lamp base connection portion 7b and the inner cylindrical wall 118c the retaining base 117 of the corresponding portion 127a of the sealing sleeve or sealing cylinder assembly 127 (preferably slightly compressed or under tension) is held sandwiched to ensure a watertight connection between the lamp base terminal portion 7b and the support base 117 here. Through the open central sections, the fluorescent lamp can then be inserted with its terminal end in the lamp base and electrically connected and held over it, in which case finally the protective cover 19 is turned on.

Abschließend wird also wie erwähnt die Lampenabdeckung 19 aufgedreht, wobei zwischen der Lampenabdeckung 19 und dem Haltesockel 117 durch die dort verwendete weitere Dichtringeinrichtung 27 eine weitere wasserdichte Gesamtverbindung realisiert wird.Finally, as mentioned, the lamp cover 19 is turned on, wherein between the lamp cover 19 and the support base 117 by the further sealing ring means 27 used there, a further watertight overall connection is realized.

Eine so vorbereitete Lichterkette kann dann problemlos im Freien eingesetzt und aufgehängt werden, wobei bevorzugt an einer zum Netzstecker 5 entfernt liegenden letzten Lampenanordnung noch ein über diese Lampenanordnung überstehendes Kabelende 3b vorgesehen ist, an dem zwar keine weitere Lampe mehr angeschlossen ist, das aber zum Aufhängen und zum Verankern der Lichterkette mit hilfreich sein kann.A light string prepared in this way can then be used and suspended in the open air without problems, wherein a cable end 3b projecting beyond this lamp arrangement is preferably provided on a last lamp arrangement remote from the power plug 5, to which no further lamp is connected, but which can be hung and to help anchor the fairy lights.
