Description

Die Erfindung bezieht sich auf eine Leuchte, die aus einer Halogenglühlampe kleiner Leistung und aus einem Sockelteil besteht, zum bajdhettartigen Einbau in eine Anzeigeeinrichtung. Die Halogenglühlampe weist an ihrem Glasquetschfußende herausgeführte Stromzuführungen und am Glasquetschfuß angeformte Rastvorsprünge auf. Das Sockelteil hat eine Aussparung zur Aufnahme der Sockelkontakte und des Glasquetschfußes der Lampe.The invention relates to a lamp, which consists of a halogen lamp of low power and a base part, for bayonet-like installation in a display device. The halogen incandescent lamp has power leads led out at the end of its glass base and snap-in projections formed on the glass base. The base part has a recess for receiving the base contacts and the glass pinch base of the lamp.

Bisher wurden die Halogenglühlampen kleiner Leistung mittels gesonderter Teile aus Metall in den Kunststoffsockeln befestigt. Da diese zusätzlichen Teile in ihrer Herstellung und bei der Montage der Leuchte extra Kosten verursachen, liegt der Erfindung die Aufgabe zugrunde, eine Leuchte mit einem Sockelteil zu schaffen, das ohne zusätzliche Halteteile die Lampe höhenfixiert aufnimmt.So far, the halogen bulbs of low power have been attached to the plastic bases using separate metal parts. Since these additional parts cause extra costs in their manufacture and in the assembly of the lamp, the object of the invention is to create a lamp with a base part which accommodates the lamp in a height-fixed manner without additional holding parts.

Die Lösung dieser Aufgabe ist im kennzeichnenden Teil des Anspruchs 1 beschrieben. Nähere Einzelheiten sind den Unteransprüchen zu entnehmen. Ein Ausführungsbeispiel der erfindungsgemäßen Leuchte wird im folgenden anhand von Zeichnungen näher beschrieben. Es zeigen

  • Figur 1 eine teilweise geschnittene Seitenansicht der Leuchte;
  • Figur 2 eine gegenüber Figur 1 um 90 um ihre Längsachse gedrehte, teilweise geschnittene Seitenansicht der Leuchte;
  • Figur 3 eine Draufsicht auf das Sockelteil der Leuchte.
The solution to this problem is described in the characterizing part of claim 1. Further details can be found in the subclaims. An embodiment of the lamp according to the invention is described below with reference to drawings. Show it
  • Figure 1 is a partially sectioned side view of the lamp;
  • FIG. 2 shows a partially sectioned side view of the lamp, rotated 90 about its longitudinal axis in relation to FIG. 1;
  • Figure 3 is a plan view of the base part of the lamp.

Die in den Zeichnungen dargestellte Leuchte besteht aus einer Halogenglühlampe 1 kleiner Leistung und einem Sockelteil 2. Die Lampe 1 weist zwei an ihrem Glasquetschfußende herausgeführte Stromzuführungen 3 auf. An den einander gegenüberliegenden Breitseiten des Glasquetschfußes 4 sind Rastvorsprünge 5 angeformt. Das Sockelteil 2 besteht vorzugsweise aus einem hochtemperaturbeständigen Kunststoff, beispielsweise Polyamid mit 25 % Glasfaser. In diesem Sockelteil 2 ist eine Aussparung 6 zur Aufnahme der Sockelkontakte 7 und des Glasquetschfußes 4 der Lampe 1 vorgesehen.The lamp shown in the drawings consists of a halogen light bulb 1 of low power and a base part 2. The lamp 1 has two power leads 3 led out at the end of its glass base. Locking projections 5 are formed on the opposite broad sides of the glass pinch foot 4. The base part 2 is preferably made of a high temperature resistant plastic, for example polyamide with 25% glass fiber. In this base part 2 there is a recess 6 for receiving the base contacts 7 and the glass pinch base 4 of the lamp 1.

In der Aussparung 6 sind Zwischenwände 8 angeformt, die bei eingesetzter Lampe 1 an den Breitseiten des Glasquetschfußes 4 in sich federnd anliegen. Zur höhenfixi-erten Halterung der Lampe 1 sind an diesen Zwischenwänden 8 auf den dem Glasquetschfuß 4 zugewandten Seiten Rasten 9, in diesem Ausführungsbeispiel in Form eines senkrecht zur Leuchtenlängsachse A angeordneten Steges an den oberen Enden der Zwischenwände 8, vorgesehen, die hinter den Rastvorsprüngen 5 der Lampe 1 eingreifen.Intermediate walls 8 are integrally formed in the recess 6, which resiliently abut on the broad sides of the glass pinch foot 4 when the lamp 1 is inserted. For height - fixed mounting of the lamp 1, catches 9, in this exemplary embodiment in the form of a web arranged perpendicularly to the longitudinal axis A of the lamp, are provided on the upper ends of the intermediate walls 8 on these intermediate walls 8, which are behind the latching projections 5 the lamp 1 intervene.

Beiderseits der Zwischenwände 8 sind zur Erweiterung der Schmalseiten der Aussparung 6 parallel zur Leuchtenlängsachse A Nuten 10 vorgesehen, in die die Sockelkontakte 7 eingeschoben sind. Mittels der Zunge 11 sind die Kontakte 7 im Sockelteil 2 verankert. An ihren unteren Enden besteht zwischen den Stromzuführungen 3 der Lampe 1 und den Sockelkontakten 7 eine Schweißverbindung. Da die Aussparung 6 im Sockelteil 2 der Leuchte durchgehend ist, ist es möglich, die Schweißverbindung im Gegensatz zu bisher bekannten Anzeigeleuchten mit Halogenglühlampen erst nach der vollständigen Montage der Leuchte herzustellen. Das obere Ende der Sokkelkontakte 7 geht in zwei Laschen über, die bei eingesetzter Leuchte beiderseits beispielsweise einer Leiterplatte (nicht dargestellt) anliegen. Gleichzeitig sind die Laschen für die bajonettartige Verankerung der Leuchte in der Leiterplatte oder Anzeigeeinrichtung vorgesehen. Die Verdrehsicherungen 12 an dem den Sockelteil 2 umlaufenden Flansch 13 unterstützen die bajonettartige Verbindung.Grooves 10 are provided on both sides of the intermediate walls 8 in order to expand the narrow sides of the recess 6, parallel to the lamp longitudinal axis A, into which the base contacts 7 are inserted. The contacts 7 are anchored in the base part 2 by means of the tongue 11. At its lower ends there is a welded connection between the power supply lines 3 of the lamp 1 and the base contacts 7. Since the recess 6 in the base part 2 of the lamp is continuous, it is possible to create the welded connection in contrast to previously known indicator lamps to be produced with halogen incandescent lamps only after the lamp has been fully assembled. The upper end of the socket contacts 7 merges into two tabs which, for example, on a printed circuit board (not shown) rest on both sides when the lamp is inserted. At the same time, the tabs are provided for the bayonet-type anchoring of the lamp in the circuit board or display device. The anti-rotation devices 12 on the flange 13 encircling the base part 2 support the bayonet-like connection.
