Description
Die Erfindung betrifft eine elektrische Lampe, bestehend aus' einem Lampenkolben, mit aus seinem Quetschfuß herausgeführten Stromzuführungen und aus einem Lampensockel. Der Lampensockel ist aus einer als Kontakt fungierenden Sockelhülse und einer den Lampenkolben tragenden Metallkappe aufgebaut, wobei die Metallkappe mit vorgegebenem Spiel in die Sockelhülse eingepaßt ist und beide Teile unlösbar miteinander verbunden sind.The invention relates to an electric lamp consisting of 'a lamp bulb, with current leads led out of its pinch base and a lamp base. The lamp base is constructed from a base sleeve acting as a contact and a metal cap supporting the lamp bulb, the metal cap being fitted into the base sleeve with a predetermined play and the two parts being inextricably linked.
In der EP-A 0 024 060 ist eine Lampe beschrieben, bei der entsprechend dem Oberbegriff des ersten Anspruches vorliegender Patentanmeldung in einem hülsenförmigen Sockel eine den Lampenkolben tragende Innenhülse angeordnet ist. Innenhülse und Sockel sind dadurch miteinander verbunden, daß der Sockel nach innen ragende Vorsprünge aufweist, über die die Nuten aufweisende Innenhülse gesteckt ist. So ist der Lampenkolben zumindest gegen Verdrehen gegenüber dem Sockel gesichert. Um eine Bewegung des Lampenkolbens in axialer Richtung zu vermeiden, sind die aus dem Lampenkolben ragenden Stromzuführungen straff gespannt mit den Sockelkontakten verlötet.EP-A 0 024 060 describes a lamp in which, in accordance with the preamble of the first claim of the present patent application, an inner sleeve carrying the lamp bulb is arranged in a sleeve-shaped base. Inner sleeve and base are connected to one another in that the base has inwardly projecting projections over which the inner sleeve having the grooves is inserted. In this way, the lamp bulb is at least secured against twisting relative to the base. In order to avoid movement of the lamp bulb in the axial direction, the power leads protruding from the lamp bulb are tightly tensioned and soldered to the base contacts.
Die Innenhülse kann auch über die Vorsprünge des Sockels verrastend aufgesetzt sein, so daß die Verbindung der Stromzuführungen mit den Sockelkontakten nur die Funktion einer elektrischen Kontaktierung hat.The inner sleeve can also be placed in a latching manner over the projections of the base, so that the connection of the power supply lines to the base contacts only has the function of an electrical contact.
Diese bekannten Arten der Verbindung sind allein zur Halterung des Lampenkolbens in dem Sockel vorgesehen. Es gibt jedoch auch Lampen für die Verwendung in optischen Systemen, deren Wendellage gegenüber dem Sockel vorjustiert sein muß.These known types of connection are provided only for holding the lamp bulb in the base. However, there are also lamps for use in optical systems, the spiral position of which must be pre-adjusted relative to the base.
Lampen beispielsweise für einen Kfz-Scheinwerfer müssen derart justiert sein, daß bei Auswechseln der Lampe mit dem Beleuchtungssystem Lampe/Scheinwerfer nach wie vor die gleiche Lichtverteilung erzielt-wird.Lamps for a motor vehicle headlight, for example, must be adjusted such that the same light distribution is still achieved when the lamp is replaced with the lamp / headlight lighting system.
Auch Kleinglühlampen beispielsweise zum Einsetzen in Taschenlampen, Fahrradscheinwerfern usw. sind vorjustiert. Bei diesen Lampen ist am Sockelboden ein erster Kontakt vorgesehen und der zweite Kontakt wird durch die Sockelhülse gebildet.Small incandescent lamps, for example for use in flashlights, bicycle headlights, etc., are also pre-adjusted. In these lamps, a first contact is provided on the base base and the second contact is formed by the base sleeve.
Der Erfindung liegt die Aufgabe zugrunde, bei Lampen, deren Sockelhülse einen Seitenkontakt bildet, eine Verbindung zwischen Lampenkolben und Sockelhülse zu schaffen, die ein einfaches Justieren der Wendellage zum Sockel während der Fertigung erlaubt und die mit möglichst wenigen Arbeitsgängen hergestellt werden kann.The invention has for its object to provide a connection between lamp bulb and base sleeve in lamps whose base sleeve forms a side contact, which allows easy adjustment of the helical position to the base during manufacture and which can be produced with as few operations.
Die gestellte Aufgabe wird dadurch gelöst, daß die Metallkappe an ihrem äußeren Rand eine etwa parallel zur Sockelachse verlaufende Nut aufweist, in die eine der Enden der Stromzuführungen eingelegt ist und Sockelhülse und Metallkappe durch Einbringen von Lot in den sich zwischen beiden Teilen befindlichen Spalt miteinander verbunden sind.The object is achieved in that the metal cap has at its outer edge a groove running approximately parallel to the base axis, into which one of the ends of the power supply lines is inserted and the base sleeve and metal cap are connected to one another by introducing solder into the gap between the two parts are.
Auf diese einfache Weise ist eine Justierung des Lampenkolbens und damit der Glühwendel gegenüber der Sockelhülse möglich bevor der Lampenkolben mittels der Metallkappe in einer bestimmten, justierten Lage endgültig mit der Sockelhülse verbunden wird.In this simple way, an adjustment of the lamp bulb and thus the filament relative to the base sleeve is possible before the lamp bulb is finally connected to the base sleeve in a certain, adjusted position by means of the metal cap.
Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels näher beschrieben. Es zeigen
Figur 1 eine gesockelte elektrische LampeFigur 2 die Metallkappe in Draufsicht- Figur 3 die Metallkappe im Schnitt.
- Figure 1 is a socketed electric lamp
- Figure 2 shows the metal cap in plan view
- Figure 3 shows the metal cap in section.
Die Lampe der Figur 1, eine Halogenglühlampe, weist einen Lampenkolben 1 aus hochschmelzendem Glas auf. Als Leuchtkörper dient eine Wolframwendel 2. Der Kolben 1 ist mit Inertgas mit Halogenzusatz gefüllt und am unteren Ende durch Quetschen verschlossen. Stromzuführungsdrähte 3 führen durch den Quetschfuß 4 nach außen. Am Quetschfuß 4 greift eine Metallkappe 5 an. Von ihrer Öffnung 6 ist der Quetschfuß 4 aufgenommen. Mit nach innen gebogenen Lappen 7 (Figur 3) stützt sich die Metallkappe 5 an Vorsprüngen 8 des Quetschungsglases ab. Die Metallkappe 5 ist zylindrisch. Zylindrisch ist auch der Lampensockel 9, in dessen metallische Sockelhülse 10 die Metallkappe 5 mit vorgegebenem Spiel eingeführt ist. Den Hülsenboden bilden Sockelstein 11 und ein zentraler Bodenkontakt 12. Die Sockelhülse 10 ist Seitenkontakt. Entsprechend ist einer der beiden Stromzuführungsdrähte 3 zum Bodenkontakt 12, der andere dagegen mit seinem Ende 3a zwischen Metallkappe 5 und Sockelhülse 10 geführt. Das Drahtende 3a ist eingelegt in eine Randnut 13 der Metallkappe 5. Die Randnut 13 verläuft etwa parallel zur Sockelachse. Eine weitere Randnut 14 ist vorgesehen, die der ersten diametral gegenüberliegt. Nach dem Justieren werden durch Ausnutzen des vorgegebenen Spiels zwischen Metallkappe und Sockelhülse dort die justierte Lampe und der Seitenkontakt mittels Lot 16 ringförmig mit der Sockelhülse 10 verlötet.The lamp in FIG. 1, a halogen incandescent lamp, has a
