Description

Technisches GebietTechnical area

Die Erfindung geht aus von einer elektrischen Lichtquelle gemäß dem Oberbegriff des Anspruchs 1. Es handelt sich dabei insbesondere um Reflektorlampen auf Basis von Hochdruckentladungslampen wie Metallhalogenidlampen oder auch Natrium-Hochdruckentladungslampen. Das Entladungsgefäß ist im allgemeinen in einem Außenkolben untergebracht. Die Erfindung ist jedoch auch bei Reflektorlampen auf Basis von Halogenglühlampen o.ä. anwendbar. Weiterhin kann es sich um eine Lampe handeln, die für den Einsatz in einer Reflektorleuchte gedacht ist.The invention relates to an electric light source according to the preamble of claim 1. These are in particular reflector lamps based on high-pressure discharge lamps such as metal halide lamps or sodium high-pressure discharge lamps. The discharge vessel is generally housed in an outer bulb. However, the invention is also in reflector lamps based on halogen incandescent lamps or similar. applicable. Furthermore, it may be a lamp, which is intended for use in a reflector lamp.

Stand der TechnikState of the art

Aus der WO 2004046609 ist eine reflektorbehaftete Metallhalogenidlampe mit einem keramischen Entladungsgefäß bekannt. Für das Sockeln einer Lampe werden die Stromzuführungen dieser Lampe, die sich nach der Vormontage in den Sockelpins des Sockels befinden und an deren Ende überstehen, mittels geeigneter Schweißverfahren fest mit dem Pinmaterial verschmolzen. Dabei ist die Stromzuführung aus dem Außenkolben herausgeführt und in einem Sockelpin verschweißt oder verlötet. Ein derartiges Verfahren schafft zwar eine sichere Verbindung, jedoch ist es schwierig, dabei den richtigen Lichtschwerpunkt für die Lampe im Reflektor einzustellen und beizubehalten.From the WO 2004046609 a reflective metal halide lamp is known with a ceramic discharge vessel. For socketing a lamp, the power supply lines of this lamp, which are located after the pre-assembly in the base pins of the base and survive at the end, fused by means of suitable welding process firmly with the pin material. The power supply is led out of the outer bulb and welded or soldered in a base pin. Although such a method provides a secure connection, it is difficult to set and maintain the correct light center of gravity for the lamp in the reflector.

Eine andere Möglichkeit der Verbindung ist die Krimpung, also die Verformung der Metallpins mit Drückverfahren. Aus der CA 2 513 931 ist eine Halogenglühlampe bekannt, bei der eine Stromzuführung, die aus einem Außenkolben herausgeführt wird, in einem ummantelnden Pin mittels einer Crimpung des Pins gehaltert wird. Dafür ist jedoch ein sehr weiches Material der Stromzuführung notwendig, das nicht immer angewendet werden kann. Ähnlich ist in DD 295 274 gezeigt, dass die Stromzuführung eine zusätzliche Kerbe aufweist. Bei Krimpung eines weichen Materials (z.B. Nickel) auf ein hartes bzw. zähes Material (z.B. Molybdän) besteht mit der bekannten Technik die Gefahr, das sich die Verbindung wieder lockert. Dies kann zu Überschlägen und Sputtern führen und außerdem zur Defokussierung des Brennermittelpunktes.Another possibility of the connection is the crimping, that is the deformation of the metal pins with spinning. From the CA 2 513 931 a halogen incandescent lamp is known in which a power supply, which is led out of an outer bulb, is held in a sheathing pin by crimping the pin. However, a very soft material of the power supply is necessary, which can not always be used. Similar is in DD 295 274 shown that the power supply has an additional notch. When crimping a soft material (eg nickel) on a hard or tough material (eg molybdenum) there is the danger with the known technique that the compound loosens again. This can lead to flashovers and sputtering and also to the defocusing of the burner center.

Eine äußere Stromzuführung, die aus dem Innengefäß herausragt, ist in die Bohrung des Kontaktpins eingeführt ist dort gehaltert.The document WO 2004/046609 discloses an electric light source arranged in a concave reflector with an inner vessel, wherein the inner vessel is mounted in a socket with at least one contact pin with a bore. An external power supply, which protrudes from the inner vessel, is inserted into the bore of the contact pin is held there.

EP 0 839 381 B1 discloses a reflector incandescent lamp, with an inner vessel held in a reflector, wherein the inner vessel is supported in a socket with at least one contact pin with bore, wherein an external power supply, which protrudes from the inner vessel, is inserted into the bore of the contact pin and held there by crimping is.

Darstellung der ErfindungPresentation of the invention

Die Aufgabe der vorliegenden Erfindung ist es, eine elektrische Lichtquelle, insbesondere für den Einsatz in einem Reflektor anzugeben, die eine dauerhafte einfache Verbindung ermöglicht, und insbesondere eine optische Justierung der Lichtquelle in einem Reflektor ermöglicht.The object of the present invention is to provide an electric light source, in particular for use in a reflector, which allows a permanent simple connection, and in particular enables an optical adjustment of the light source in a reflector.

Diese Aufgabe wird gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved by the characterizing features of claim 1.

Besonders vorteilhafte Ausgestaltungen finden sich in den abhängigen Ansprüchen.Particularly advantageous embodiments can be found in the dependent claims.

Erfindungsgemäß sind die äußeren Stromzuführungen der Lichtquelle jeweils einseitig mit mehreren Einkerbungen versehen, wobei die Stromzuführung aus einem zähen bzw. harten Material, insbesondere Molybdän o.ä. hergestellt ist, und wobei mindestens ein Sockelpin zur Befestigung verwendet wird, der im Bereich der Einkerbungen vercrimpt wird.According to the invention the outer power supply lines of the light source are each provided on one side with a plurality of notches, wherein the power supply of a tough or hard material, in particular molybdenum or the like. is manufactured, and wherein at least one base pin is used for fastening, which is crimped in the region of the notches.

Die Mindestanzahl an Einkerbungen beträgt zwei, bevorzugt mindestens drei. Die Crimpung sollte sich wenigstens auf eine Einkerbung, bevorzugt über mindestens zwei Einkerbungen, erstrecken. Im Prinzip ist es möglich, nur eine Einkerbung zu verwenden, jedoch ist dann nur eine minimale Anpassungsfähigkeit gegeben, die nur von der Länge der Crimpung abhängt.The minimum number of notches is two, preferably at least three. The crimp should extend at least to a notch, preferably over at least two indentations. In principle, it is possible to use only one notch, but then there is only a minimum adaptability, which depends only on the length of the crimp.

Erfindungsgemäß wird eine Fixierung der Stromzuführungen einer Lichtquelle, hier auch als Basislampe bezeichnet, in den Metallkontakten, hier oft auch als Sockelpin bezeichnet, eines Sockels, bevorzugt eines Keramiksockels, mittels Crimpung erreicht. Dabei wird die zu fixierende Stromzuführung einseitig mit Einkerbungen wie Kerben oder Schlitzen versehen. Dies bewirkt eine formschlüssige Verbindung zwischen Pin-Material und Material der Stromzuführung.According to the invention, a fixation of the power supply lines of a light source, also referred to herein as a base lamp, in the metal contacts, often referred to here as Sockelpin, a base, preferably a ceramic base, achieved by crimping. The power supply to be fixed is provided on one side with notches such as notches or slots. This causes a positive connection between pin material and material of the power supply.

Dadurch wird eine sichere elektrische Kontaktierung zwischen Sockelpin und Stromzuführung der Basislampe erzielt. Dies bewirkt eine mechanische Fixierung der Basislampe, insbesondere des Leuchtmittels, das meist im Mittelpunkt des Kolbens angeordnet ist, im konstruktiven Fokuspunkt eines Reflektors nach der Justierung beim Einbau in den Reflektor.As a result, a secure electrical contact between Sockelpin and power supply of the base lamp is achieved. This causes a mechanical fixation of the base lamp, in particular of the illuminant, which is usually arranged in the center of the piston, in the constructive focus point of a reflector after the adjustment during installation in the reflector.

Die aus der Basislampe herausragenden Stromzuführungen werden erfindungsgemäß innerhalb einer definierten Strecke mit mehreren Kerben versehen. Die Strecke ist so zu wählen, das der spätere Krimpbereich überdeckt wird.The projecting from the base lamp power supply according to the invention provided within a defined route with multiple notches. The route is to be chosen so that the later crimping area is covered.

Die Form der Einkerbungen kann dabei unterschiedlich sein.The shape of the notches can be different.

Es entsteht eine formschlüssige Verbindung, die sich nicht mehr bei üblicher Belastung lösen kann. Die Festigkeit der Verbindung wird deutlich erhöht. Eine Lockerung der Verbindung, z.B. durch den Transport der Lampen, wird durch die verzahnten Materialien verhindert.The result is a positive connection that can not solve under normal load. The strength of the connection is significantly increased. Relaxation of the compound, e.g. by transporting the lamps, is prevented by the toothed materials.

Im Prinzip kann diese Art der Krimpung auch bei anderen Lichtquellen angewendet werden, bei denen es auf eine dauerhafte Justierung oder eine schweißfreie Verbindung ankommt.In principle, this type of crimping can also be applied to other light sources where a permanent adjustment or a sweat-free connection is required.

Das Innengefäß kann ein Entladungsgefäß allein oder mit Außenkolben sein. Es kann auch der Kolben einer Halogenglühlampe sein. Der Sockel ist bevorzugt aus Keramik.The inner vessel may be a discharge vessel alone or with outer bulb. It can also be the bulb of a halogen incandescent lamp. The base is preferably made of ceramic.

Im Detail wird eine Reflektorlampe mit einem Innengefäß vorgestellt, das in einem Reflektor fixiert ist, wobei das Innengefäß in einem Sockel mit mindestens einem Kontaktpin mit Bohrung gehaltert ist. Eine äußere Stromzuführung, die aus dem Innengefäß herausragt, ist in die Bohrung des Kontaktpins eingeführt und dort mittels Crimpung gehaltert, wobei die Stromzuführung mit mehreren Einkerbungen versehen ist und wobei der Kontaktpin auf die Stromzuführung aufgecrimpt ist.In detail, a reflector lamp is presented with an inner vessel which is fixed in a reflector, wherein the inner vessel is mounted in a socket with at least one contact pin with bore. An external power supply, which protrudes from the inner vessel is inserted into the bore of the contact pin and held there by crimping, wherein the power supply is provided with a plurality of notches and wherein the contact pin is crimped onto the power supply.

Eine besonders sichere Halterung wird dadurch erreicht, dass der Kontaktpin so auf die Stromzuführung aufgecrimpt ist, dass die Crimpstrecke mindestens zwei der Einkerbungen überdeckt.A particularly secure holder is achieved in that the contact pin is crimped onto the power supply, that the crimping covers at least two of the notches.

Bevorzugt ist die Stromzuführung aus Molybdän gefertigt, so dass die Lampe an Luft betreiben werden kann. Bevorzugt ist der Sockelpin aus weichem Material, das gut crimpfähig ist. Insbesondere ist der Kontaktpin aus Messing, Kupfer oder Nickel oder einer Legierung davon gefertigt.Preferably, the power supply is made of molybdenum, so that the lamp can be operated in air. Preferably, the base pin is made of soft material, which is good crimpable. In particular, the contact pin is made of brass, copper or nickel or an alloy thereof.

Eine bevorzugte konkrete Anwendung ist eine Reflektorlampe mit einem Innengefäß das ein Entladungsgefäß mit einer Metallhalogenidfüllung als einziges Gefäß, oder auch aufgenommen in einem Außenkolben, beinhaltet.A preferred concrete application is a reflector lamp with an inner vessel containing a discharge vessel with a metal halide filling as a single vessel, or also accommodated in an outer bulb.
