Die Erfindung geht aus von einer zweiseitig gequetschten Lampe gemäß
dem Oberbegriff des Anspruchs 1.The invention is based on a lamp pinched on both sides
the preamble of
Darunter sind sowohl Glühlampen als auch Entladungslampen zu verstehen. Es handelt sich dabei insbesondere um Halogenglühlampen in Soffittenform, aber auch um Entladungslampen, insbesondere Metallhalogenidlampen, beispielsweise UV-Strahler für kosmetische und medizinische Anwendungen. Ein weiteres Anwendungsgebiet sind Natriumhochdrucklampen.This includes both incandescent and discharge lamps. These are, in particular, halogen incandescent lamps in the form of a festoon, but also discharge lamps, in particular metal halide lamps, for example UV lamps for cosmetic and medical applications. Another area of application is high pressure sodium lamps.
Üblicherweise sind derartige Lampen mit Sockeln versehen, die aus einer keramischen Hülse und einem darin gehaltenen metallischen Anschlußkontakt bestehen. Meist ist der Anschlußkontakt scheibenähnlich geformt, insbesondere knopfartig oder tellerartig. Die Hülse ist normalerweise geschlitzt, wobei der Schlitz auf die Quetschung aufgeschoben ist. Sie ist mittels Kitt an der Quetschung befestigt. Die Verwendung von Kitt ist mit einigen Nachteilen behaftet. Insbesondere ist die damit erzielte Verbindung bei hoher Temperaturbelastung nicht genügend zuverlässig. Weiterhin können das saure Milieu des Kitts und Reste von Lösungsmitteln die Stromzuführung korrodieren. Aus diesem Grund wurde bereits versucht, die keramische Hülse kittlos zu befestigen (siehe beispielsweise EP-A 547 683). Die Herstellung derartiger Lampen ist jedoch sehr kompliziert und damit zeit- und kostenaufwendig.Such lamps are usually provided with bases which consist of a ceramic sleeve and a metallic connection contact held therein consist. The connection contact is usually shaped like a disk, in particular button-like or plate-like. The sleeve is usually slotted the slot being pushed onto the pinch. It is on with putty attached to the bruise. The use of putty has some disadvantages afflicted. In particular, the connection achieved in this way is at high temperature loads not reliable enough. Furthermore, the acidic Putty milieu and residues of solvents corrode the power supply. For this reason, the ceramic sleeve has already been tried to be fixed without cement (see for example EP-A 547 683). The production However, such lamps are very complicated and therefore time-consuming and expensive.
Es ist Aufgabe der vorliegenden Erfindung, eine zweiseitig gequetschte
Lampe gemäß dem Oberbegriff des Anspruchs 1 bereitzustellen, die zeitund
kostengünstig hergestellt werden kann und die sich insbesondere gut
für die Automatisierung eignet.It is an object of the present invention to provide a two-sided crimp
Providing lamp according to the preamble of
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1
gelöst. Besonders vorteilhafte Ausgestaltungen finden sich in den abhängigen
Ansprüchen.This object is achieved by the characterizing features of
Der Vorteil der vorliegenden Erfindung besteht darin, daß das keramische Hülsenmaterial jetzt völlig eingespart werden kann und damit auch auf Kitt vollständig verzichtet werden kann. Das zeitaufwendige Ausheizen des Sokkelkitts entfällt völlig. Das Formen der Glassockelhülse kann bevorzugt gleichzeitig mit dem Fertigungsschritt des Quetschens durchgeführt werden.The advantage of the present invention is that the ceramic Sleeve material can now be completely saved and therefore also on putty can be completely dispensed with. The time-consuming baking of the rock cement completely eliminated. Forming the glass base sleeve may be preferred be carried out at the same time as the squeezing step.
Erfindungsgemäß besteht die zweiseitig gequetschte elektrische Lampe aus einem vakuumdicht abgeschlossenen, längsgestreckten Lampenkolben, der eine Längsachse definiert. Er ist an seinen beiden einander gegenüberliegenden Enden mit Quetschdichtungen ausgestattet, wobei jede Quetschdichtung eine Quetschfolie umschließt, die innere und äußere Stromzuführungen miteinander verbindet. An den äußeren Enden der Quetschdichtungen sind jeweils Lampensockel angebracht. Diese bestehen aus einer Hülse, die aus dem Material des Lampenkolbens gebildet ist und die an das äußere Ende der Quetschdichtung angeformt ist. Diese Hülse besitzt einen inneren und äußeren Durchmesser, wobei die Wandstärke der Hülse typenspezifisch in der Größenordnung von etwa einem Millimeter liegt. Im Innern der Hülse ist ein Kontaktelement befestigt, das mit der äußeren Stromzuführung elektrisch leitend verbunden ist. Das Kontaktelement erstreckt sich im wesentlichen quer zur Lampenachse.According to the invention, the electric lamp is pinched on both sides a vacuum-sealed, elongated lamp bulb, the defines a longitudinal axis. He is on his two opposite one another Ends equipped with press seals, each press seal a crimp film encloses the inner and outer power supply lines connects with each other. At the outer ends of the pinch seals are each lamp base attached. These consist of a sleeve that is made of the material of the lamp bulb is formed and to the outer end the press seal is molded. This sleeve has an inner and outer diameter, the wall thickness of the sleeve type-specific in is on the order of about one millimeter. Inside the sleeve is attached a contact element that is electrically connected to the external power supply is conductively connected. The contact element extends essentially across the lamp axis.
Die Grundform des Kontaktelements ist scheibenähnlich. Insbesondere eignen sich auch davon abgeleitete Formen wie pilz-, stift- oder messerähnliche Kontaktelemente. Die Befestigung des Elements in der Hülse erfolgt dadurch, daß zumindest ein Teil des Randes des Kontaktelements in die Hülse eingebettet, also eingeschmolzen oder eingequetscht, ist.The basic shape of the contact element is disc-like. Particularly suitable derived forms such as mushroom, pencil or knife-like Contact elements. The element is fastened in the sleeve by that at least part of the edge of the contact element in the sleeve embedded, i.e. melted or squeezed, is.
In einer besonders bevorzugten Ausführungsform ändert sich der Abstand des Randes des scheibenähnlichen Körpers von seinem Mittelpunkt, also sein Radius, über den Umfang. Er ändert sich insbesondere gesetzmäßig bzw. periodisch. Diese Eigenschaft ist besonders dann wichtig, wenn es praktisch kein metallisches Material für das Kontaktelement gibt, das dem thermischen Ausdehnungskoeffizienten des Kolbenmaterials (im allgemeinen Quarzglas) angepaßt wäre. Eine Fehlanpassung würde jedoch im Betrieb bald zu Sprüngen im Kolbenmaterial (Quarzglas) führen, die die Lebensdauer der Lampe verkürzen würden. Ein geeignetes Material für das Kontaktmaterial ist Edelstahl (V2A, insbesondere auch vernickelt) oder auch Nickel bzw. Kupfer (evtl. versilbert oder vergoldet). In a particularly preferred embodiment, the distance changes of the edge of the disk-like body from its center, ie its Radius, over the perimeter. In particular, it changes legally or periodically. This property is especially important when it is practical there is no metallic material for the contact element that corresponds to the thermal Expansion coefficient of the piston material (generally quartz glass) would be adjusted. However, a mismatch would soon lead to jumps in operation in the bulb material (quartz glass), which extend the life of the lamp would shorten. A suitable material for the contact material is stainless steel (V2A, especially also nickel-plated) or nickel or copper (possibly silver-plated or gold-plated).
In einer besonders bevorzugten Ausführungsform ist der minimale Radius des Elements kleiner als der Innenradius der Hülse. Insbesondere hat das Kontaktelement eine kleeblattähnliche, elliptische, dreiecksähnliche oder einem n-Eck ähnliche Gestalt. Für die praktische Ausführung hat es sich als vorteilhaft erwiesen, wenn die Ecken des Kontaktelements abgerundet sind. Auf diese Weise können Spannungen minimiert werden, insbesondere bei gleichzeitiger Anwendung beider Techniken. Letztlich wird dadurch das Kontaktelement sehr zuverlässig in der Glashülse verankert.In a particularly preferred embodiment, the minimum radius is of the element is smaller than the inner radius of the sleeve. In particular, that has Contact element a shamrock-like, elliptical, triangular-like or one Shape similar to n-corner. For the practical execution, it has proven to be proven to be advantageous if the corners of the contact element are rounded. In this way, stresses can be minimized, especially with simultaneous use of both techniques. Ultimately it will Contact element anchored very reliably in the glass sleeve.
Die äußere Stromzuführung, die die Quetschfolie mit dem Kontaktelement verbindet, kann prinzipiell auf zwei verschiedene Weisen realisiert werden.The outer power supply line connecting the crimp film to the contact element connects, can in principle be realized in two different ways.
Eine erste Möglichkeit ist, daß die äußere Stromzuführung ein Draht ist. Vorteilhaft besitzt dabei das Kontaktelement ein ösenähnliches Ansatzstück (Halsteil), in das der Draht eingesetzt werden kann. Eine zweite Variante ist, die drahtförmige Stromzuführung abzuwinkeln und die Längsseite des Winkelstücks am Kontaktelement zu verschweißen. Schließlich kann das Kontaktelement auch direkt mit dem Draht stumpf verschweißt werden.A first possibility is that the external power supply is a wire. Advantageous the contact element has an eyelet-like extension (Neck part) in which the wire can be inserted. A second variant is bend the wire-shaped power supply and the long side of the To weld elbow on the contact element. After all, it can Contact element can also be butt welded directly to the wire.
Eine zweite Möglichkeit ist, daß die äußere Stromzuführung eine Folie, insbesondere eine Verlängerung der Quetschfolie, ist. Die übliche Quetschfolie ist stabil genug um die Aufgabe der äußere Stromzuführung mit zu übernehmen. Auch hier ist bevorzugt ein Verlängerungsteil der Quetschfolie abgewinkelt, wobei wieder die Längsseite des Winkelstücks am Kontaktelement verschweißt ist.A second possibility is that the outer power supply is a foil, in particular an extension of the crimp film. The usual squeeze film is stable enough to take on the task of external power supply. Here too, an extension part of the squeeze film is preferably angled, again the long side of the elbow on the contact element is welded.
Im Falle der Abwinkelung eines Teils der äußeren Stromzuführung ist es vorteilhaft, daß das Kontaktelement zur Stromzuführung hin ausgebaucht ist. An dieser konkaven Wölbung kann das Winkelstück gut verschweißt werden.In the case of bending part of the external power supply, it is advantageous that the contact element bulges toward the power supply is. The angle piece can be welded well to this concave curvature become.
Für eine zuverlässige Halterung des Kontaktelements in der Glashülse hat es sich als günstig erwiesen, wenn zumindest der Rand des Kontaktelements eine Dicke zwischen 0,3 und 0,8 mm besitzt. In einer besonders bevorzugten Ausführungsform gilt diese Bemessungsregel für das ganze Kontaktelement.It has for a reliable mounting of the contact element in the glass sleeve proved to be favorable if at least the edge of the contact element has a thickness between 0.3 and 0.8 mm. In a particularly preferred This design rule applies to the entire contact element.
Die Herstellung derartiger Sockel aus Glashülsen läßt sich vorteilhaft in den üblichen Herstellungsablauf für derartige Lampen einbinden wie er beispielsweise (mit Hilfe einer Vierbackenquetschmaschine) in der EP-A 451 647 beschrieben ist. Zur Herstellung des erfindungsgemäßen Sockels enthalten die Backen jetzt jeweils eine integrierte Formeinrichtung, die nicht nur die Quetschung, sondern auch die Glashülse formt. Dabei wird zunächst als Zwischenschritt das Ende des Lampenkolbens, insbesondere auch der Bereich der späteren Glashülse, auf Verformungstemperatur gebracht. Durch die Oberflächenspannung kommt es dadurch zu einer definierten Selbstverformung des Kolbenendes, so daß sich dort der Rohrdurchmesser einschnürt. Durch die der beabsichtigten Sockelform angepaßten Formbacken wird nun ein Verschluß des Kolbens durch die Quetschbacken erreicht. Gleichzeitig wird die Sockelgeometrie geprägt, wobei das Kontaktelement mittels Unterdruck oder durch eine Zange an die richtige Stelle gehalten wird. Ein definierter Innendurchmesser der Glashülse wird durch geeignet gewählte Verarbeitungsparameter erreicht.The production of such bases from glass sleeves can be advantageously in the Integrate the usual manufacturing process for such lamps as he, for example (with the help of a four-jaw squeezing machine) in EP-A 451 647 is described. Included in the manufacture of the base according to the invention the jaws now each have an integrated molding device, which is not only the Contusion, but also forms the glass sleeve. First, it is called Intermediate step the end of the lamp bulb, especially the area the later glass sleeve, brought to the deformation temperature. By the surface tension results in a defined self-deformation of the piston end, so that the pipe diameter constricts there. Through the shaped jaws adapted to the intended base shape the piston is now closed by the pinch jaws. At the same time, the base geometry is shaped, with the contact element held in place using vacuum or pliers becomes. A defined inner diameter of the glass sleeve is indicated by selected processing parameters reached.
