II. Darstellung der Erfindung II. Presentation of the invention

Es ist die Aufgabe der Erfindung, für einen gattungsgemäßen Reflektor und für eine gattungsgemäße Reflektorlampe eine verbesserte Befestigung der elektrischen Kontaktelemente für die im Reflektor angeordnete Lampe anzugeben.It is the object of the invention to provide for a generic reflector and for a generic reflector lamp an improved attachment of the electrical contact elements for the lamp arranged in the reflector.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 bzw. 5 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Patentansprüchen beschrieben.This object is achieved by the features of claim 1 and 5, respectively. Particularly advantageous embodiments of the invention are described in the dependent claims.

Der erfindungsgemäße Reflektor und die erfindungsgemäße Reflektorlampe weisen einen aus einem elektrisch isolierenden Kunststoff bestehenden Reflektorkörper auf, der mit einer lichtreflektierenden Innenseite und einer Außenseite sowie mit mindestens einem Durchbruch für die Lampe oder für ein Lampenteil versehen ist. Der Reflektor bzw. die Reflektorlampe weist mindestens eine Kontaktfahne auf, die an mindestens zwei unterschiedlichen Orten des Reflektorkörpers mittels Krallen oder Widerhaken, die an der mindestens einen Kontaktfahne angeformt sind, am Reflektorkörper fixiert ist.The reflector according to the invention and the reflector lamp according to the invention have a reflector body consisting of an electrically insulating plastic, which is provided with a light-reflecting inner side and an outer side and with at least one opening for the lamp or for a lamp part. The reflector or the reflector lamp has at least one contact lug, which is fixed to the reflector body at at least two different locations of the reflector body by means of claws or barbs, which are integrally formed on the at least one contact lug.

Durch die erfindungsgemäße Kombination der obengenannte Merkmale des Reflektors bzw. der Reflektorlampe kann auf die Verwendung eines Keramik-Sockelsteins gemäß des oben zitierten Gebrauchsmusters verzichtet werden. Da der Reflektorkörper statt aus Aluminium aus einem elektrisch isolierenden Material besteht, wird keine elektrische Isolierung zwischen den elektrischen Kontaktelementen und dem Reflektor benötigt, um einen Kurzschluß zwischen den Lampenstromzuführungen zu vermeiden. Die mit Krallen oder Widerhaken versehenen Kontaktfahnen können in dem Material des Kunststoffreflektors verkrallt werden und ermöglichen so eine einfache Fixierung der Kontaktfahnen am Reflektor.Due to the inventive combination of the above-mentioned features of the reflector or the reflector lamp can be dispensed with the use of a ceramic socket stone according to the above-cited utility model. Since the reflector body instead of aluminum is made of an electrically insulating material, no electrical insulation between the electrical contact elements and the reflector is needed to avoid a short circuit between the Lampenstromzuführungen. The contact lugs provided with claws or barbs can be clawed in the material of the plastic reflector and thus allow easy fixation of the contact lugs on the reflector.

Vorteilhafterweise weist der Reflektorkörper mindestens einen an seine Außenseite angeformten Zapfen auf und ein erster Schenkel der mindestens einen abgewinkelten Kontaktfahne weist einen Durchbruch auf, in dem der mindestens eine Zapfen mit Klemmsitz angeordnet ist, wobei der Rand des vorgenannten Durchbruchs mit Krallen oder Widerhaken versehen ist. Alternativ oder zusätzlich dazu besitzt die mindestens eine abgewinkelte Kontaktfahne vorteilhafterweise einen sich quer zu ihrem ersten Schenkel erstreckenden Teil, der mit mindestens einer Kralle oder einem Widerhaken ausgestattet und in einer Vertiefung an der Außenseite des Reflektorkörpers angeordnet ist. Die mindestens eine Kontaktfahne ist vorzugsweise mittels eines derartigen Zapfens und eines sich quer zum ersten Schenkel erstreckenden Teils der mindestens einen Kontaktfahne am Reflektorkörper befestigt. Alternativ kann die mindestens eine Kontaktfahne auch mittels zweier derartiger Zapfen oder zweier sich quer zum ersten Schenkel erstreckender Teile der mindestens einen Kontaktfahne am Reflektorkörper fixiert werden. Die Krallen oder Widerhaken der mindestens einen Kontaktfahne verkrallen oder verhaken sich in dem Kunststoffmaterial der Zapfen bzw. in den Kunststoffwänden der Vertiefungen an der Reflektoraußenseite.Advantageously, the reflector body has at least one pin formed on its outside and a first leg of the at least one angled contact lug has an opening in which the at least one pin is arranged with a clamping fit, wherein the edge of the aforementioned opening is provided with claws or barbs. Alternatively or additionally, the at least one angled contact lug advantageously has a part which extends transversely to its first limb and is provided with at least one claw or a barb and is arranged in a recess on the outside of the reflector body. The at least one contact lug is preferably fastened to the reflector body by means of such a pin and of a part of the at least one contact lug extending transversely to the first limb. Alternatively, the at least one contact lug can also be fixed to the reflector body by means of two such pins or two parts of the at least one contact lug extending transversely to the first limb. The claws or barbs of the at least one contact lug dig into or get caught in the plastic material of the pegs or in the plastic walls of the pits on the reflector outside.

Der mit den Krallen oder Widerhaken versehene, sich quer zu dem ertsen Schenkel erstreckende Teil der Kontaktfahne ist vorteilhafterweise als Bestandteil ihres zweiten Schenkels ausgebildet, der von dem ersten Schenkel abgewinkelt ist und zum Einführen in eine entsprechende Lampenfassung dient. Durch diese Maßnahme wird eine besonders hohe mechanische Stabilität der Kontaktfahne erreicht, weil der mit dem mindestens einen Widerhaken versehene, in dem Reflektorkörper verkrallte Teil der Kontaktfahne dadurch entgegengesetzt zu demjenigen Abschnitt der Kontaktfahne angeordnet ist, der zum Einführen in die Lampenfassung vorgesehen ist. Außerdem ist vorteilhafterweise zumindest ein Abschnitt des zweiten Schenkels der mindestens einen Kontaktfahne zweilagig ausgebildet, um die mechanische Stabilität der Kontaktfahne weiter zu erhöhen. Vorzugsweise ist derjenige Abschnitt des zweiten Schenkels der mindestens einen Kontaktfahne, der zum Einführen in eine Lampenfassung vorgesehen ist, zweilagig ausgebildet, das heißt, das freie Ende des zweiten Schenkels der mindestens einen Kontaktfahne ist um einen Winkel von 180 Grad zurückgebogen. Der mit dem mindestens einen Widerhaken ausgestattete Teil der Kontaktfahne bildet vorzugsweise das einlagig ausgeführte, sich diametral zu dem zweilagig ausgebildeten Abschnitt erstreckende Ende des zweiten Schenkels der Kontaktfahne.The provided with the claws or barbs, extending transversely to the ertsen leg portion of the contact lance is advantageously formed as part of its second leg, which is angled from the first leg and serves for insertion into a corresponding lamp socket. By this measure, a particularly high mechanical stability of the contact lug is achieved because the provided with the at least one barb, verkrallte in the reflector body part of the contact lug is arranged opposite to that portion of the contact lug, which is provided for insertion into the lamp holder. In addition, advantageously, at least a portion of the second leg of the at least one contact lug is formed in two layers to further increase the mechanical stability of the contact lug.

Das freie Ende 521 schließt mit dem ersten Schenkel 51 einen Winkel von 80 Grad und mit dem zweilagigen Abschnitt 520 einen Winkel von 190 Grad ein. Mit anderen Worten formuliert bedeutet das, dass der zweite Schenkel 52 im Winkel von 90 Grad von dem ersten Schenkel 51 abgewinkelt ist, im Abstand von 11,28 mm um einen Winkel von 180 Grad zurückgebogen ist, und sein freies Ende 521 auf der Höhe des ersten Schenkels 51 um einen Winkel von 10 Grad aus der Ebene des zweilagigen Abschnitts 520 abgewinkelt ist, so dass das freie Ende 521 des zweiten Schenkels 52 mit dem ersten Schenkel 51 einen Winkel von 80 Grad einschließt. Der zweilagige Abschnitt 520 besitzt daher eine Länge von ungefähr 11,3 mm. Das freie Ende 521 des zweiten Schenkels 52 der Kontaktfahne 5 ist in der Vertiefung 15 an der Außenseite 12 des Reflektorkörpers 10 angeordnet und dort mittels der Widerhaken 522 verkrallt. Analog dazu ist die andere Kontaktfahne 6 in der Vertiefung 16 und an dem Zapfen 18 fixiert.The second leg 52 of the angled contact lug 5 has a two-layered section 520, which adjoins directly to the first leg 51 and is arranged at right angles to the first leg 51. This two-ply section 520 is for insertion into a correspondingly adapted to the G53 socket lamp socket. The free end 521 of the second leg 52 is single-layered and provided with two punched barbs 522, which are bent out of the plane of the free end 521. The free end 521 makes an angle of 80 degrees with the first leg 51 and an angle of 190 degrees with the two-layer portion 520. In other words, this means that the second leg 52 is bent at an angle of 90 degrees from the first leg 51, bent back at an interval of 11.28 mm by an angle of 180 degrees, and its free end 521 at the height of first leg 51 is angled at an angle of 10 degrees from the plane of the two-ply portion 520, so that the free end 521 of the second leg 52 with the first leg 51 forms an angle of 80 degrees. The two-ply portion 520 therefore has a length of about 11.3 mm. The free end 521 of the second leg 52 of the contact lug 5 is arranged in the recess 15 on the outer side 12 of the reflector body 10 and there clawed by means of the barbs 522. Similarly, the other contact lug 6 is fixed in the recess 16 and on the pin 18.

Die Lampe 2 wird in dem Reflektor 1 ausschließlich durch die mit den Kontaktfahnen 5, 6 verschweißten Stromzuführungen 21, 22 getragen. Es ist aber auch möglich, zur weiteren Stabilisierung und Erhöhung der Erschütterüngsfestigkeit einen ringförmigen Abstandshalter vorzusehen, der zwischen dem Gefäß der Lampe 2 und dem Rand des Durchbruchs 13 angeordnet ist und zur Abstützung der Lampe 2 an dem Rand des Durchbruchs 13 dient.The lamp 2 is supported in the reflector 1 exclusively by the power leads 21, 22 welded to the contact lugs 5, 6. However, it is also possible to provide an annular spacer for further stabilization and increase the vibration resistance, which is arranged between the vessel of the lamp 2 and the edge of the opening 13 and serves to support the lamp 2 at the edge of the opening 13.

Die Erfindung beschränkt sich nicht auf das oben näher erläuterte bevorzugte Ausführungsbeispiel. Beispielsweise kann auch der in der Vertiefung verkrallte Abschnitt 521 zweilagig und der in die Lampenfassung einsetzbare Abschnitt 520 der Kontaktfahnen 5, 6 einlagig ausgebildet sein, um beispielsweise die Federwirkung des zweilagig ausgebildeten Abschnitts zur Erzielung einer Klemmwirkung auszunutzen.The invention is not limited to the above-described preferred embodiment. For example, the portion 521 engaged in the recess can also be designed in two layers in two layers and the section 520 of the contact lugs 5, 6 which can be inserted into the lamp holder, in order to utilize, for example, the spring effect of the two-layered section to achieve a clamping action.
