For this purpose, resilient struts (8) are arranged within the base, which face the base base part (5) at an angle, and which engage in corresponding depressions formed in the pinch (2) of the discharge vessel (1). The struts (8) are preferably formed on a separate clamp part (7) which is inserted into the base. The base also contains a clamping part (9) made of an elastic material, onto which a pressure is exerted by fastening the base cap (6) to the base part (5). As a result, the clamp part (7) and the discharge vessel are additionally held on the one hand.

Description

Die Erfindung betrifft eine einseitig gesockelte Entladungslampe mit einem Entladungsgefäß, dessen in einem Sockel endender und dort befestigter Teil eine oder mehrere Abdichtungen in Form einer Quetschung aufweist, und der Sockel ein Sockelunterteil und eine Sockelkappe enthält.The invention relates to a discharge lamp with a base on one side and a discharge vessel, the part of which ends in a base and is fastened there has one or more seals in the form of a pinch, and the base contains a base part and a base cap.

Die Befestigung des Sockels an dem Ende des Entladungsgefäßes erfolgt bekannterweise, indem ein Teil des in der Sockelkappe befindlichen Hohlraumes mit einem durch Temperatur aushärtenden Sockelkitt ausgefüllt wird. Die feste, unlösbare Verbindung entsteht somit erst, nachdem eine bestimmte Temperatur über einen bestimmten Zeitraum auf diese zu verbindenden Teile und damit auch auf den Sockelkitt eingewirkt hat. Dieser Vorgang ist in der Herstellung der Lampen wegen der dafür erforderlichen und ständig zu beheizenden Sockelmaschine nicht nur kostenaufwendig, sondern darüber hinaus auch zeitraubend. Die Verwendung von Sockeln, die ganz aus Kunststoff bestehen, ist zudem stark eingeschränkt, da einerseits der Sockelkitt eine bestimmte Mindesttemperatur für das Aushärten benötigt, andererseits jedoch das Kunststoffmaterial ohne deformiert zu werden nur eine bestimmte Maximaltemperatur verträgt.As is known, the base is fastened to the end of the discharge vessel by filling part of the cavity located in the base cap with a temperature-hardening base cement. The firm, non-detachable connection is therefore only created after a certain temperature has acted on these parts to be connected and thus also on the base cement over a certain period of time. This process is not only costly in the manufacture of the lamps because of the base machine which is required for this purpose and which is constantly to be heated, but is also time-consuming. The use of bases which are made entirely of plastic is also severely restricted, since on the one hand the base cement requires a certain minimum temperature for curing, but on the other hand the plastic material can only withstand a certain maximum temperature without being deformed.

Aufgabe der Erfindung ist es, den Sockel einer einseitig gesockelten Entladungslampe derart zu gestalten, daß das zeitaufwendige und kostenintensive Hantieren mit dem Sockelkitt nicht mehr erforderlich ist.The object of the invention is to design the base of a discharge lamp with a base on one side in such a way that the time-consuming and costly handling of the base cement is no longer necessary.

Die einseitig gesockelte Entladungslampe mit den im Oberbegriff des Hauptanspruchs genannten Merkmalen ist dadurch gekennzeichnet, daß innerhalb des Sockels Elemente angeordnet sind, die mit dem im Sockel endenden Teil des Entladungsgefäßes form- und kraftschlüssig verbunden sind und dieses kittlos in dem Sockel haltern. Die Quetschung des Entladungsgefäßes ist beidseitig und mindestens an einem Teil ihrer Breite mit einer oder mehreren Vertiefungen versehen. Alternativ dazu können die Quetschungen auch beidseitig und mindestens an einem Teil ihrer Breite mit einer oder mehreren Erhebungen versehen sein. Außerdem sind die innerhalb des Sockels angeordneten Elemente als federnde Streben ausgebildet, die in die Vertiefungen in der Quetschung des Entladungsgefäßes einrasten bzw. die hinter den Erhebungen an den Quetschungen anliegen. Die Streben sind nach der Art von Widerhaken schräg nach unten dem Sokkelunterteil zugeneigt. Die Schräge ermöglicht ein besonders leichtes Einführen der Quetschung des Endes eines Entladungsgefäßes. Während des Einführens öffnen sich die Streben etwas und rasten mit ihren gegenüberliegenden Enden in den in der Quetschung angebrachten Vertiefungen bzw. hinter den Erhebungen ein. Ein Herausziehen des Entladungsgefäßes ohne Zerstörung mindestens eines dieser Teile ist jedoch aufgrund der Schrägstellung der Streben nicht mehr möglich, da sich diese mit zunehmender Zugkraft von selbst mehr und mehr schließen.The discharge lamp with a base on one side with the features mentioned in the preamble of the main claim is characterized in that elements are arranged within the base which are positively and non-positively connected to the part of the discharge vessel ending in the base and hold this in the base without cement. The squeezing of the discharge vessel is provided on both sides and at least over part of its width with one or more depressions. Alternatively, the bruises can also be provided on both sides and at least on part of their width with one or more elevations. In addition, the elements arranged within the base are designed as resilient struts which snap into the depressions in the pinch of the discharge vessel or which rest against the pinches behind the elevations. The struts are inclined downwards towards the lower part of the base in the manner of barbs. The bevel enables particularly easy insertion of the pinch at the end of a discharge vessel. During the insertion, the struts open slightly and engage with their opposite ends in the depressions made in the pinch or behind the elevations. However, pulling out the discharge vessel without destroying at least one of these parts is no longer possible due to the inclined position of the struts, since these automatically close more and more as the tensile force increases.

Außerdem ist innerhalb des Sockels ein elastisches Klemmteil eingequetscht, das auf Druck das Ende des Entladungsgefäßes eng anliegend umgibt und dieses zusätzlich haltert.In addition, an elastic clamping part is squeezed inside the base, which tightly surrounds the end of the discharge vessel when pressed and additionally holds it.

Die Streben sind vorzugsweise an ein separates Klammerteil angeformt, das in den Sockel eingesetzt ist. Das Klammerteil liegt in einer ersten Ausführungsform auf dem Sockelunterteil auf, während das Klemmteil wiederum auf dem Klammerteil aufliegt. Die den Sockel oben abschließende Sockelkappe liegt mit Druck ihrerseits auf dem Klemmteil und ist mit dem Sockelunterteil verbunden. Auf diese Weise wirkt das auf Druck beanspruchte Klemmteil halternd für das Entladungsgefäß und das Klammerteil. In einer alternativen Ausführungsform ist das Klammerteil mittels einer Rastverbindung mit der Sockelkappe verbunden, die dann wiederum mit dem Sockelunterteil verbunden ist.The struts are preferably molded onto a separate clamp part which is inserted into the base. The In a first embodiment, the clamp part rests on the base part, while the clamp part in turn rests on the clamp part. The base cap that closes the base at the top lies with pressure on the clamping part and is connected to the base part. In this way, the clamping part, which is subjected to pressure, acts as a holder for the discharge vessel and the clamping part. In an alternative embodiment, the clip part is connected to the base cap by means of a snap-in connection, which in turn is then connected to the base part.

Für die Montage der Lampe ergibt sich der Vorteil, daß ausschließlich mit vorgefertigten Teilen aus Kunststoff gearbeitet werden kann. Nach dem Zusammenbau der Einzelteile ist die Lampe sofort fertig, da die langen Zeiten zum Aufheizen, Aushärten und Abkühlen des Sokkelbereiches bei der Sockelung mit Sockelkitt entfallen. Darüber hinaus wird während des Sockelns gegenüber dem konventionellen Sockelverfahren Heizenergie eingespart. Die Lampe mit der neuartigen Konstruktion wird somit schneller und kostengünstiger hergestellt. Hinsichtlich der Abziehfestigkeit des Sockels, der Stabilität des Entladungsgefäßes innerhalb des Sockels werden die gleichen Werte wie für eine konventionelle Sockelung erreicht. Die elektrische Sicherheit wird durch die Verwendung von Kunststoffteilen erheblich erhöht. Das Grundkonzept der neuartigen Sockelkonstruktion ist auch bei mehrendigen Entladungsgefäßen anwendbar. Des weiteren ist eine vergleichbare Sockelung in abgewandelter Form auch bei unterschiedlichen Sockeltypen möglich. Bei Verwendung von entsprechend großräumigen Sockelgehäusen ist ebenso die Integration eines Starters sowie ggf. eines Vorschaltgerätes möglich.For the assembly of the lamp there is the advantage that it is only possible to work with prefabricated plastic parts. After assembling the individual parts, the lamp is ready immediately, since the long times for heating, hardening and cooling of the base area are no longer necessary when plinthing with plaster. In addition, heating energy is saved during plinthing compared to the conventional plinth method. The lamp with the new design is thus manufactured faster and cheaper. With regard to the peel strength of the base, the stability of the discharge vessel within the base, the same values are achieved as for a conventional base. Electrical safety is significantly increased through the use of plastic parts. The basic concept of the new base construction can also be used for multi-ended discharge vessels. Furthermore, a comparable base in a modified form is also possible with different base types. The integration of a starter and, if necessary, a ballast is also possible when using correspondingly large base housings.

Die Erfindung wird nachstehend anhand eines bevorzugten Ausführungsbeispiels erläutert:

  • Figur la zeigt eine Ansicht der Sockelkonstruktion
  • Figur Ib zeigt eine alternative Ausführungsform einer Sockelkonstruktion
  • Figur 2 zeigt eine um 90o gedrehte Ansicht der Sockelkonstruktion aus Figur 1
  • Figur 3 zeigt die Verbindung zwischen dem Sockelunterteil und der Sockelkappe
The invention is explained below using a preferred exemplary embodiment:
  • Figure la shows a view of the base construction
  • Figure Ib shows an alternative embodiment of a base construction
  • Figure 2 shows a 90 o rotated view of the base structure of Figure 1
  • Figure 3 shows the connection between the base part and the base cap

Die in den Figuren la und 2 in unterschiedlichen Ansichten dargestellte Sockelkonstruktion zeigt ein U-förmig gebogenes Entladungsgefäß 1 mit den in Form einer Quetschung 2 eingeschmolzenen zwei Enden. Die Quetschungen 2 sind jeweils am Rand und auf beiden Seiten mit einer Nut 3 versehen. Mit 4 ist die Abschmelzspitze eines Pumprohres bezeichnet. Die Enden des Entladungsgefäßes 1 münden in einen Sockel, der ein mit einer Fassung korrespondierendes Sockelunterteil 5 und eine Sockelkappe 6 aufweist. Zwischen diesen beiden Teilen ist ein Klammerteil 7 (z.B. Pocan) angeordnet, das an beiden den Quetschungen 2 des Entladungsgefäßes 1 zugewandten Seiten mit Streben 8 versehen ist. Diese Streben 8 weisen schräg nach unten in Richtung Sockelunterteil 5 und sind in die Nuten 3 jeder Quetschung 2 eingerastet. Zwischen dem Klammerteil 7 und der Sockelkappe 6 ist ein elastisches Klemmteil 9 (z.B. Silopren) eingequetscht, das die Enden des Entladungsgefäßes 1 etwa in Form einer Acht eng umgibt und an diese angedrückt ist. Das Sockelunterteil 5 ist weiterhin unterhalb jedes Endes des Entladungsgefäßes 1 mit je einem Höhenanschlag 12 versehen, wodurch dessen Position genau festgelegt ist.The base construction shown in FIGS. 1 a and 2 in different views shows a U-shaped discharge vessel 1 with the two ends melted in the form of a pinch 2. The bruises 2 are each provided with a groove 3 on the edge and on both sides. The melting tip of a pump tube is designated by 4. The ends of the discharge vessel 1 open into a base which has a base part 5 corresponding to a socket and a base cap 6. A clamp part 7 (for example Pocan) is arranged between these two parts and is provided with struts 8 on both sides facing the bruises 2 of the discharge vessel 1. These struts 8 point obliquely downwards in the direction of the base part 5 and are engaged in the grooves 3 of each pinch 2. An elastic clamping part 9 (for example siloprene) is squeezed between the clamp part 7 and the base cap 6, which tightly surrounds the ends of the discharge vessel 1 in the form of an eight and is pressed against it. The base part 5 is further below each end of the discharge vessel 1 with one Provide height stop 12, whereby its position is precisely determined.

In der Figur 1b sind gleiche Teile mit gleicher Bezifferung versehen. Der Unterschied zu der Figur la besteht lediglich darin, daß die Quetschung 2 des Entladungsgefäßes 1 an ihrem Ende und auf beiden Seiten mit Erhebungen 3' versehen ist. Die federnden Streben 8 liegen direkt hinter den Erhebungen 3' und an der verdünnt ausgeführten Quetschung 2 an. Hierdurch wird der gleiche vorteilhafte Klemmeffekt wie in dem Ausführungsbeispiel der Figur 1a erreicht.In FIG. 1b, the same parts are provided with the same numbering. The only difference from FIG. 1 a is that the pinch 2 of the discharge vessel 1 is provided with elevations 3 'at its end and on both sides. The resilient struts 8 are directly behind the elevations 3 'and the diluted pinch 2. This achieves the same advantageous clamping effect as in the exemplary embodiment in FIG. 1a.

Ein Beispiel der Verbindungsart zwischen dem Sockelunterteil 5 und der Sockelkappe 6 ist in Figur 3 dar-, gestellt. In das Sockelunterteil 5 ist eine Hohlkehle 10 eingearbeitet. Die Sockelkappe 6 weist an der entsprechenden Stelle eine Nase 11 auf, die in die Hohlkehle 10 einschnappt. Beide Teile sind aus Kunststoff (z.B. Pocan) im Spritzgußverfahren hergestellt.An example of the type of connection between the base part 5 and the base cap 6 is shown in FIG. A groove 10 is incorporated into the base part 5. The base cap 6 has a nose 11 at the corresponding point, which snaps into the fillet 10. Both parts are made of plastic (e.g. Pocan) by injection molding.

Die elektrischen Anschlußstifte 13 (Figur 2) des Sokkels sind am Sockelunterteil (5) befestigt. Innerhalb des Hohlraums 14 ist Raum für einen Starter (nicht dargestellt) vorgesehen. Die Nocken 15 (Figur 1) dienen für die Befestigung der gesockelten Lampe in einer Fassung.The electrical connection pins 13 (FIG. 2) of the base are fastened to the base part (5). Space for a starter (not shown) is provided within the cavity 14. The cams 15 (FIG. 1) serve for fastening the base lamp in a socket.
