Description

Die Erfindung bezieht sich auf eine Leuchte zur Beleuchtung einer Anzeigeeinrichtung, die aus einer Halogenglühlampe kleiner Leistung mit an ihrem Glasquetschfußende herausgeführten Stromzuführungsstiften und einem topfförmigen Sockelteil aus Kunststoff besteht.The invention relates to a luminaire for illuminating a display device, which consists of a low-power halogen incandescent lamp with power supply pins led out at the end of its glass base and a pot-shaped base part made of plastic.

Bisher wurden in vielen Fällen zur Beleuchtung von Anzeigeeinrichtungen kleine Glassockellampen verwendet, die in Kunststoffsockel eingesetzt sind. Entweder sind sie dort von im Sockel angeformten Klemm- oder Rastelementen oder von geeignet geformten Sockelkontakten lagefixiert gehalten.So far, small glass base lamps used in plastic bases have been used in many cases for illuminating display devices. Either they are held there in a fixed position by means of molded-on clamping or locking elements or by suitably shaped base contacts.

Um eine intensivere Beleuchtung für Anzeigeeinrichtungen zu erhalten, sollen nun die gegenüber den Glassockellampen wesentlich (um das 2- bis 4fache) größeren Halogenglühlampen kleiner Leistung, beispielsweise 12 V, 5 W oder 12 V, ca. 8 W eingesetzt werden.In order to obtain more intensive lighting for display devices, the halogen incandescent lamps of smaller wattage, for example 12 V, 5 W or 12 V, approximately 8 W, which are substantially larger (by 2 to 4 times) than the glass base lamps, should now be used.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte zur intensiveren Beleuchtung einer Anzeigeeinrichtung zu schaffen, die in ihrer Bauhöhe relativ niedrig einfach in ihrer Herstellung und leicht gegen das Gehäuse der Anzeigeeinrichtung abzudichten ist.The invention has for its object to provide a luminaire for more intense lighting of a display device, which is relatively low in height, simple to manufacture and easy to seal against the housing of the display device.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Halogenglühlampe kleiner Leistung Verwendung findet, diese mittels einer Befestigungsscheibe im topfförmigen Sockelteil lagefixiert gehalten ist, die Stromzuführungsstifte der Lampe durch Bohrungen im Boden des Sockelteils nach außen geführt und diese anschließend dichtend verklebt sind und schließlich das Sockelteil entweder in die Gehäusewandung der Anzeigeeinrichtung eingeformt ist oder wenn das Sockelteil ein von der Gehäusewandung getrenntes Teil ist, Mittel zur Abdichtung des Gehäuses aufweist.The object is achieved in that a low-power halogen incandescent lamp is used, which is held in position by means of a fastening disk in the pot-shaped base part, which Power supply pins of the lamp are guided through bores in the base of the base part to the outside and these are then sealed and finally the base part is either molded into the housing wall of the display device or if the base part is a part separate from the housing wall, has means for sealing the housing.

Die in den Figuren dargestellten Ausführungsformen von Anzeigeleuchten bestehen aus einer Halogenglühlampe 1 kleiner Leistung (12 V, 5 W oder 12 V, ca. 8 W), die mit ihrem Glasquetschfuß 2 in der Öffnung 3 einer Befestigungsscheibe 4 gehaltert ist. Die Öffnung 3 weist an ihrem Umfang Laschen und Vorsprünge auf, die mit am Glasquetschfuß 2 der Lampe 1 angeformten Nocken zusammenwirken.The embodiments of indicator lights shown in the figures consist of a halogen incandescent lamp 1 of low power (12 V, 5 W or 12 V, approx. 8 W) is held with its glass crimping foot 2 in the opening 3 of a mounting disk 4. The opening 3 has tabs and projections on its circumference, which cooperate with cams formed on the glass pinch base 2 of the lamp 1.

Die Lampe 1 ist zusammen mit der Befestigungsscheibe 4 in das topfförmige Sockelteil 5.1 - 5.4 aus Kunststoff eingesetzt. Ein Anschlag bzw. Vorsprung 6 verhindert, daß Lampe 1 und Befestigungsscheibe 4 zu tief in das Sockelteil 5.1 - 5.4 hineinrutschen. Mittels eines abgebogenen, gezackten Randes 7 (s. Fig. 2) ist die Befestigungsscheibe 4, dadurch, daß sich die Zackenspitzen in das Material des Sockelteils 5.1 - 5.4 verkrallen, gegen Herausfallen und Verdrehen gesichert.The lamp 1 is inserted together with the mounting disk 4 in the pot-shaped base part 5.1 - 5.4 made of plastic. A stop or projection 6 prevents the lamp 1 and the fastening disk 4 from sliding too deep into the base part 5.1-5.4. By means of a bent, serrated edge 7 (see FIG. 2), the fastening disk 4 is secured against falling out and twisting, because the tips of the teeth claw into the material of the base part 5.1-5.4.

Die Stromzuführungsstifte 8 der Lampe 1 sind durch Bohrungen 9 im Boden des topfförmigen Sockelteils 5.1 - 5.4 nach außen geführt, um die Lampe 1 elektrisch anzuschließen. Um Eindringen von Staub und Feuchtigkeit zu verhindern, ist der verbleibende Raum in der Bohrung 9 mit einem geeigneten Klebstoff verschlossen.The power supply pins 8 of the lamp 1 are guided through holes 9 in the bottom of the pot-shaped base part 5.1 - 5.4 to the outside to connect the lamp 1 electrically. In order to prevent the ingress of dust and moisture, the remaining space in the bore 9 is closed with a suitable adhesive.

Die äußeren Formen der Sockelteile 5.1 - 5.4 der einzelnen Anzeigeleuchten sind recht unterschiedlich ausgestaltet. Um die Anzeigeeinrichtung ganz sicher gegen Staub- und Feuchtigkeitseindringen zu schützen, ist das Sockelteil 5.1 im ersten Ausführungsbeispiel einer Anzeigeleuchte (s. Fig. 1) in die Gehäusewandung 10.1 der Anzeigeeinrichtung eingeformt. Ein Auswechseln der Lampe 1 bei eventuellem Ausfall ist dann jedoch nicht möglich.The outer shapes of the base parts 5.1 - 5.4 of the individual indicator lights are designed quite differently. In order to protect the display device against dust and moisture penetration, the base part 5.1 in the first exemplary embodiment of a display lamp (see FIG. 1) is molded into the housing wall 10.1 of the display device. A replacement of the lamp 1 in the event of a failure is then not possible.

Die Figuren 3a, b, 4a, b und 5 zeigen auswechselbare Anzeigeleuchten. Die Sockelteile 5.2, 5.3 der zweiten und dritten Ausführungsform von Anzeigeleuchten weisen an ihrem unteren Ende je einen umlaufenden Flansch 11 auf, auf dessen Oberseite eine Ringdichtung 12 angeformt ist. Bei eingesetzter Leuchte liegt die Ringdichtung 12 an der Außenseite der Gehäusewandung 10.2, 10.3 an, wodurch das Innere der Anzeigeeinrichtung nach außen hin abgedichtet ist.Figures 3a, b, 4a, b and 5 show interchangeable indicator lights. The base parts 5.2, 5.3 of the second and the third embodiment of indicator lights each have a peripheral flange 11 at their lower end, on the top of which an annular seal 12 is formed. When the lamp is inserted, the ring seal 12 bears against the outside of the housing wall 10.2, 10.3, as a result of which the inside of the display device is sealed off from the outside.

Die Leuchten nach der zweiten und dritten Ausführungsform sind durch am Umfang des Sockelteils 5.2, 5.3 federnd angeordneten Rastnasen 13.1, 13.2, die die Gehäusewandung 10.2, 10.3 hintergreifen, in einer Öffnung in der Anzeigeeinrichtung befestigt. Das Sockelteil 10.2 der zweiten Ausführungsform einer Anzeigeleuchte weist zwei einander gegenüberliegende Rastnasen 13.1 auf und das Sockelteil 10.3 der dritten Ausführungsform beispielsweise acht gleichmäßig am Umfang verteilte Rastnasen 13.2.The lights according to the second and third embodiments are fastened in an opening in the display device by latching lugs 13.1, 13.2 which are resiliently arranged on the circumference of the base part 5.2, 5.3 and which engage behind the housing wall 10.2, 10.3. The base part 10.2 of the second embodiment of an indicator light has two mutually opposite latching lugs 13.1 and the base part 10.3 of the third embodiment, for example, eight latching lugs 13.2 distributed uniformly around the circumference.

Bei der in Figur 5 dargestellten Ausführungsform einer Anzeigeleuchte ist das Rastelement zur Halterung der Leuchte in der Gehäusewandung 10.4 der Anzeigeeinrichtung als eine am oberen Ende des Sockelteils 5.4 angeformte Ringwulst 14 ausgebildet. Am unteren Ende des Sockelteils 5.4 ist ein stufenförmiger Flansch 15 vorgesehen. Die Öffnung in der Gehäusewandung 10.4 der Anzeigeeinrichtung ist zur Befestigung der Leuchte von einem Zylindermantel 16 eingefaßt, an dessen oberen Ende eine Ringnut 17 vorgesehen ist. Die Ringnut 17 wirkt mit der Ringwulst 14 des Sockelteils 5.4 zusammen. Der stufenförmige Flansch 15 liegt bei eingebauter Leuchte am unteren Ende des Zylindermantels 16 an und dichtet die Anzeigeeinrichtung zuverlässig ab.In the embodiment of an indicator lamp shown in FIG. 5, the latching element for holding the lamp in the housing wall 10.4 of the display device is designed as an annular bead 14 formed on the upper end of the base part 5.4. A step-shaped flange 15 is provided at the lower end of the base part 5.4. The opening in the housing wall 10.4 of the display device is enclosed by a cylinder jacket 16 for fastening the lamp, at the upper end of which an annular groove 17 is provided. The annular groove 17 interacts with the annular bead 14 of the base part 5.4. When the lamp is installed, the stepped flange 15 lies against the lower end of the cylinder jacket 16 and reliably seals the display device.
