Description

Die Erfindung betrifft einen Adapter für eine einseitig gesockelte Niederdruckentladungslampe, deren Sockel einen zylindrischen Führungszapfen sowie mindestens zwei Kontaktstifte aufweist, und der Adapter aus einem zweiteiligen Gehäuse mit einem für Glühlampen gebräuchlichen Sockel besteht, der innerhalb des Gehäuses eine Montageplatte sowie die die Kontaktstifte aufnehmenden Gegenkontakte enthält, und am Oberteil des Gehäuses Aufnahmen für den Führungszapfen und die Kontaktstifte vorgesehen sind.The invention relates to an adapter for a low-pressure discharge lamp with a base on one side, the base of which has a cylindrical guide pin and at least two contact pins, and the adapter consists of a two-part housing with a base customary for incandescent lamps, which contains a mounting plate inside the housing and the mating contacts receiving the contact pins , and recordings for the guide pin and the contact pins are provided on the upper part of the housing.

Adapter, die den Anschluß von Entladungslampen, insbesondere von kleinen Leuchtstofflampen, direkt in eine für Glühlampen vorgesehene Leuchte ermöglichen, sind in verschiedenen Ausführungsformen bekannt. Als ein Beispiel hierfür sei das DE-GM 82 33 763 angeführt. Hier sind jeweils zwei mit einem Stiftsockel versehene einseitig gesockelte Kompaktleuchtstofflampen auf einem eine Vorschalt- und Zündvorrichtung halternden Körper in Fassungen montiert. Die dargestellten Formen weisen jedoch eine große Breite auf, so daß der Adapter nicht in jede Leuchte einsetzbar ist und die Einsatzmöglichkeiten entsprechend beschränkt sind.Adapters that enable the connection of discharge lamps, in particular small fluorescent lamps, directly into a lamp intended for incandescent lamps are known in various embodiments. DE-GM 82 33 763 is cited as an example of this. Here, two compact fluorescent lamps with a pin base are mounted on a body holding a ballast and ignition device. However, the shapes shown have a large width, so that the adapter cannot be used in every lamp and the possible uses are correspondingly limited.

Aufgabe der Erfindung ist es, einen Adapter für eine einseitig gesockelte Leuchtstofflampe zu schaffen, der eine kompakte Bauform aufweist, leicht zu montieren ist und der einen sicheren Betrieb der Leuchtstofflampe gewährleistet.The object of the invention is to provide an adapter for a fluorescent lamp with a base on one side, which has a compact design, is easy to assemble and which ensures safe operation of the fluorescent lamp.

Der Adapter für eine einseitig gesockelte Niederdruckentladungalampe mit den im Oberbegriff des Hauptanspruchs genannten Merkmalen ist dadurch gekennzeichnet, daß die Montageplatte die Aufnahme für den Führungezapfen mindestens teilweise umgibt und die Gegenkontakte direkt auf der Montageplatte befestigt sind. Die Gegenkontakte sind als federnde, den Kontaktstift zweiseitig umschließende Kontaktfahnen ausgebildet. Weiterhin sind die Gegenkontakte zur Befestigung auf der Montageplatte mit Befestigungsfahnen und zur elektrischen Kontaktierung der Montageplatte mit Kontaktfahnen versehen. Auf diese Weine wird die Lampe von dem Oberteil des zweiteiligen Adapters mechanisch gehaltert, während die elektrische Kontaktierung getrennt vom Oberteil über die Gegenkontakte auf der Montageplatte erfolgt, die wiederum zwischen dem Unterteil mit dem Oberteil des Adapters befestigt ist. Auf der Montageplatte ist außerdem die Vorschalt- und Zündvorrichtung für den Lampenbetrieb montiert. Hierfür sind konventionelle, induktive Geräte geeignet, jedoch werden wegen ihres geringeren Gewichts und ihrer höheren Lichtausbeute häufig elektronisch arbeitende Geräte bevorzugt.The adapter for a low-pressure discharge lamp with a base on one side with the features mentioned in the preamble of the main claim is characterized in that the mounting plate at least partially surrounds the receptacle for the guide pin and the mating contacts are fastened directly on the mounting plate. The counter contacts are designed as resilient contact lugs enclosing the contact pin on both sides. Furthermore, the mating contacts for attachment to the mounting plate are provided with mounting tabs and for electrical contacting of the mounting plate with contact tabs. On these wines, the lamp is mechanically supported by the upper part of the two-part adapter, while the electrical contact is made separately from the upper part via the mating contacts on the mounting plate, which in turn is fastened between the lower part and the upper part of the adapter. The ballast and ignition device for lamp operation is also mounted on the mounting plate. Conventional inductive devices are suitable for this, however, because of their lower weight and their higher luminous efficacy, electronically operating devices are often preferred.

Die Erfindung wird nachfolgend an Hand von drei Figuren näher erläutert:

  • Figur 1 zeigt einen Schnitt durch einen Adapter entsprechend der Erfindung
  • Figur 2 zeigt eine Ausführungsform eines Kontaktelements im Detail
  • Figur 3 zeigt eine weitere Ausführungsform eines Kontaktelementes
The invention is explained in more detail below with the aid of three figures:
  • Figure 1 shows a section through an adapter according to the invention
  • Figure 2 shows an embodiment of a contact element in detail
  • Figure 3 shows a further embodiment of a contact element

Der Adapter 1 der Figur 1 besteht aus einem Oberteil 2 und einem Unterteil 3, die mittels einer Schnappverbindung miteinander unlösbar befestigt sind. An das Oberteil 2 ist eine zylindrische Aufnahme 4 angeformt, in der ein Führungszapfen 5 des Sockels 6 einer Leuchtstofflampe 7 eingeführt ist. Der Führungszapfen 5 ist mit Haltenasen (nicht erkennbar) versehen, hinter denen Schnappfedern 8 eingreifen und so den Sockel 6 der Lampe 7 in der Aufnahme 4 mechanisch haltern. Der obere abgesetzte Teil der Aufnahme 4 ist mit Aufnahmen 9 versehen, durch die die Kontaktstifte 10 des Sockels 6 in den Innenteil des Adapters 1 ragen.The adapter 1 of Figure 1 consists of an upper part 2 and a lower part 3, which are non-detachably fastened to one another by means of a snap connection. On the upper part 2, a cylindrical receptacle 4 is formed, in which a guide pin 5 of the base 6 of a fluorescent lamp 7 is inserted. The guide pin 5 is provided with retaining lugs (not recognizable), behind which snap springs 8 engage and thus mechanically hold the base 6 of the lamp 7 in the receptacle 4. The upper, offset part of the receptacle 4 is provided with receptacles 9 through which the contact pins 10 of the base 6 protrude into the inner part of the adapter 1.

Zwischen dem Unterteil 3 und dem Oberteil 2 des Adapters 1 ist eine Montageplatte 11 mittels Klemmung befestigt, auf der die Vorschalt- und Zündvorrichtung 12 montiert ist. Hierfür ist ein induktives Vorschaltgerät mit Starter oder ein elektronisches Vorschaltgerät gleichermaßen geeignet. Im vorliegenden Ausführungsbeispiel ist die Montageplatte 11 eine Leiterplatte, auf der die Bauteile eines Hochfrequenzvorschaltgerätes angeordnet sind. Dieses bietet die Vorteile einer höheren Lichtausbeute der Lampe sowie des gegenüber einem konventionellen Vorschaltgerät wesentlich verringerten Gewichts. Des weiteren sind in die Montageplatte 11 Kontaktelemente 13, 13' eingelassen und dort mittels Verschränken ihrer Befestigungsfahnen 14, 14' befestigt (Figuren 2 und 3). Die oberen Kontaktfahnen 15, 15' sind zunächst im spitzen Winkel zueinander gebogen und öffnen sich dann nach oben wieder, um das Einführen der Kontaktstifte 10 zu erleichtern. Insgesamt sind je nach Ausführungsform der Lampe zwei oder vier dieser Kontaktelemente 13, 13' auf der Montageplatte 11 angeordnet, wobei jedem Kontaktelement 13, 13' ein Kontaktstift 10 der Leuchtstofflampe 7 zugeordnet ist. Die Kontaktelemente 13, 13' bestehen vorzugsweise aus vernickelter Federbronze, um einerseits eine dauerhafte Federwirkung und Korrosionsbeständigkeit zu haben und andererseits das Verlöten der Kontaktfahnen 16 (Figur 2) mit der Leiterplatte 11 zu erleichtern, sofern nicht eine lötfreie elektrische Verbindung mittels federnder Kontaktfahnen 16' (Figur 3) bevorzugt wird.Between the lower part 3 and the upper part 2 of the adapter 1, a mounting plate 11 is fastened by means of clamping, on which the ballast and ignition device 12 is mounted. An inductive ballast with starter or an electronic ballast is equally suitable for this. In the present exemplary embodiment, the mounting plate 11 is a printed circuit board on which the components of a high-frequency ballast are arranged. This offers the advantages of a higher luminous efficacy of the lamp as well as the significantly reduced weight compared to a conventional ballast. Furthermore, contact elements 13, 13 'are embedded in the mounting plate 11 and fastened there by interlocking their fastening tabs 14, 14' (FIGS. 2 and 3). The upper contact lugs 15, 15 'are initially bent at an acute angle to one another and then open upwards again in order to facilitate the insertion of the contact pins 10. Depending on the embodiment of the lamp, a total of two or four of these contact elements 13, 13 'are arranged on the mounting plate 11, with each contact element 13, 13' being assigned a contact pin 10 of the fluorescent lamp 7. The contact elements 13, 13 'are preferably made of nickel-plated spring bronze, on the one hand to have a permanent spring action and corrosion resistance and on the other hand to facilitate the soldering of the contact lugs 16 (FIG. 2) to the printed circuit board 11, unless a solderless electrical connection by means of resilient contact lugs 16' (Figure 3) is preferred.

Am unteren Bereich des Unterteils 3 ist weiterhin ein Sockel 17 befestigt, wie er gewöhnlich für Glühlampen verwendet wird. Ein Kontaktelement 13 sowie die Vorschalt- und Zündvorrichtung 12 sind elektrisch mit dem Sockel 17 verbunden, so daß der Betrieb der Lampe 7 über den Adapter 1 direkt in einer für Glühlampen vorgesehenen Fassung einer Leuchte erfolgen kann.At the bottom of the lower part 3, a base 17 is also attached, as is usually used for incandescent lamps. A contact element 13 and the ballast and ignition device 12 are electrically connected to the base 17, so that the lamp 7 can be operated directly via the adapter 1 in a luminaire socket provided for incandescent lamps.
