Das Lampengehäuse 1 ist Teil eines Scheinwerfers für Film-, Studio-, Bühnenbeleuchtung oder weitere Anwendungsbereiche und weist in an sich bekannter Weise insbesondere ein Zündgerät, einen Lampenhalter, eine Lampe bzw. einen Brenner und einen Reflektor auf. Von dem Lampengehäuse 1 ist in Figur 1 nur ein zylindrischer Abschnitt dargestellt, an den der Lampenvorsatz 3 angekoppelt werden soll. Dabei sind verschiedene Lampenvorsätze 3 vorgesehen, die jeweils unterschiedliche Lichtführungssyteme aufweisen.In Figure 1, a lamp housing 1 is shown, which is connectable by means of a connecting ring with a lamp attachment 3. The lamp housing 1 is part of a headlamp for film, studio, stage lighting or other applications and has in a conventional manner in particular an ignitor, a lamp holder, a lamp or a burner and a reflector. Of the lamp housing 1, only a cylindrical portion is shown in Figure 1, to which the lamp attachment 3 is to be coupled. In this case, different lamp attachments 3 are provided, each having different Lichtführungssyteme.

Wie im folgenden erläutert, wird über den Verbindungsring 2 eine einfache und schnelle Verbindung zwischen dem Lampengehäuse 1 und einem gewünschten Lampenvorsatz 3 bereitgestellt.As explained below, a simple and fast connection between the lamp housing 1 and a desired lamp attachment 3 is provided via the connecting ring 2.

Gemäß den Figuren 2 bis 4 weist der Verbindungsring 2 einen ersten Bereich 22, über den der Verbindungsring drehbar mit dem Gehäuse 1 und einen zweiten Bereich 21, über den der Verbindungsring mit dem Lampenhalter 3 verbindbar ist, auf. Die beiden Bereiche 21, 22 des Verbindungsrings sind axial beabstandet. Sie weisen einen geringfügig unterschiedlichen Durchmesser auf, wodurch am Grenzbereich zwischen den beiden Bereichen eine innenliegende, umlaufende Anschlagkante 23 entsteht, an der das entsprechende Kopplungsteil des Lampenhalters 3 zur Anlage kommt.According to FIGS. 2 to 4, the connecting ring 2 has a first region 22, via which the connecting ring is rotatably connected to the housing 1 and a second region 21, via which the connecting ring can be connected to the lamp holder 3. The two areas 21, 22 of the connecting ring are axially spaced. They have a slightly different diameter, whereby at the boundary region between the two areas, an inner, circumferential stop edge 23 is formed at which the corresponding coupling part of the lamp holder 3 comes to rest.

Alternativ kann auch vorgesehen sein, daß der erste und der zweite Bereich 21, 22 den gleichen Durchmesser aufweisen und ein umlaufender Steg zur Trennung der beiden Bereiche an der Innenseite des Verbindungsrings 2 angeordnet ist.Alternatively, it can also be provided that the first and the second region 21, 22 have the same diameter and a circumferential ridge for separating the two regions is arranged on the inside of the connecting ring 2.

An der Innenseite des Verbindungsrings 2, und zwar sowohl in dem einen Bereich 21 als auch in dem anderen Bereich 22 sind drei gleichmäßig verteilte Rollen angeordnet, die um eine senkrecht zur Oberfläche des Verbindungsrings verlaufende Achse drehbar gelagert sind. Entsprechende Lageröffnungen 24 für diese Rollen sind in der Schnittansicht der Figur 3 dargestellt.On the inside of the connecting ring 2, both in the one area 21 and in the other area 22, three uniformly distributed rollers are arranged, which are rotatably mounted about an axis perpendicular to the surface of the connecting ring. Corresponding bearing openings 24 for these rollers are shown in the sectional view of FIG.

Die in dem einen Bereich 22 angeordneten Rollen dienen der Verbindung des Verbindungsrings 2 mit dem Lampengehäuse 1 und die in dem anderen Bereich 21 des Verbindungsrings angeordneten Rollen der Verbindung mit dem Lampenvorsatz 3. In der Figur 1 ist eine entsprechende Verbindungsrolle 25 in dem einen Bereich 21 des Verbindungsrings dargestellt. Eine entsprechende Rolle 27 im Bereich 22 des Verbindungsrings zeigt die Figur 7.The rollers arranged in the one region 22 serve to connect the connecting ring 2 to the lamp housing 1 and the rollers of the connection to the lamp attachment 3 arranged in the other region 21 of the connecting ring. FIG. 1 shows a corresponding connecting roller 25 in the one region 21 represented the connecting ring. A corresponding roller 27 in the region 22 of the connecting ring is shown in FIG. 7.

Gemäß den Figuren 2 und 4 sind an dem äußeren Umfang des Verbindungsrings eine Vielzahl von Griffmulden 26 ausgebildet, die eine sichere Handhabung des Verbindungsrings 2 gewährleistet und ein Verdrehen des Verbindungsrings 2 erleichtern. Die Griffmulden können dabei mit einem wärmeisolierenden Kunststoff versehen sein (nicht dargestellt).According to Figures 2 and 4, a plurality of recessed grips 26 are formed on the outer periphery of the connecting ring, which ensures a secure handling of the connecting ring 2 and facilitate a rotation of the connecting ring 2. The recessed grips can be provided with a heat-insulating plastic (not shown).

Die Verbindung des Verbindungsrings 2 mit dem Lampengehäuse 1 ist in Figur 5 dargestellt. Danach bildet das Lampengehäuse an seinen dem anzukoppelnden Lampenvorsatz zugewandten Enden einen zylindrischen Koppelbereich bzw. Absatz 11 auf, der eine umlaufende Nut 12 ausbildet. Der Außendurchmesser des Absatzes 11 entspricht dabei im wesentlichen dem Innendurchmesser des Verbindungsrings 2. In der umlaufenden Nut 12 laufen drei Rollen 27 (vgl. Figur 7), die in dem Lampengehäuse 1 zugeordneten Bereich 22 des Verbindungsrings gleichmäßig verteilt angeordnet sind. Hierdurch wird eine drehbare und unverlierbare Verbindung zwischen dem Verbindungsring 2 und dem Lampengehäuse 1 hergestellt.The connection of the connecting ring 2 with the lamp housing 1 is shown in FIG. Thereafter, the lamp housing forms at its ends to be coupled lamp attachment facing a cylindrical coupling region or paragraph 11, which forms a circumferential groove 12. The outer diameter of the shoulder 11 corresponds essentially to the inner diameter In the circumferential groove 12 run three rollers 27 (see Figure 7), which are arranged distributed uniformly in the lamp housing 1 associated region 22 of the connecting ring. As a result, a rotatable and captive connection between the connecting ring 2 and the lamp housing 1 is produced.

Aufgrund der beweglichen Rollen 25 ist ein gleichmäßiges, ruckfreies und leichtgängiges Drehen des Verbindungsrings 2 gegenüber dem Lampengehäuse 1 möglich.Due to the movable rollers 25 is a uniform, smooth and smooth turning of the connecting ring 2 relative to the lamp housing 1 is possible.

Gemäß den Figuren 6a, 6b erfolgt die Verbindung des Verbindungsrings 2 mit dem anzukoppelnden Lampenvorsatz 3 dadurch, daß die in dem Bereich 21 des Verbindungsrings 2 angeordneten Rollen 25 in bajonettartig ausgebildete Nuten 31 des Lampenvorsatzes 3 eingreifen.According to FIGS. 6a, 6b, the connection of the connecting ring 2 to the lamp attachment 3 to be coupled takes place in that the rollers 25 arranged in the region 21 of the connecting ring 2 engage in bayonet-shaped grooves 31 of the lamp attachment 3.

Der Lampenvorsatz 3 weist dabei als Koppelbereich einen zylindrischen Bereich bzw. Absatz 32 auf, in den insgesamt drei bajonettartige Nuten 31 eingebracht sind. Die Nuten 31 sind gleichmäßig an dem Absatz 32 verteilt und korrespondieren in ihrer Lage mit den Rollen 25 des Verbindungsrings 2. Sie weisen eine dem Verbindungsring 2 zugewandte Einkoppel-öffnung 31b auf und verlaufen dann mit geringer Steigung schräg zur Längsachse des Lampenvorsatzes 3.The lamp attachment 3 has a cylindrical region or shoulder 32 as the coupling region, into which a total of three bayonet-type grooves 31 are made. The grooves 31 are uniformly distributed on the shoulder 32 and correspond in position to the rollers 25 of the connecting ring 2. They have a coupling ring 2 facing the coupling opening 31b and then extend at a slight pitch obliquely to the longitudinal axis of the lamp attachment third

Zur Verbindung des Lampenvorsatzes 3 mit dem Lampengehäuse 1 ist es lediglich erforderlich, daß der Absatz 32 des Lampenvorsatzes 3 in den Verbindungsring 2 eingesetzt wird. Bei einem anschließendem Drehen des Verbindungsrings 2 werden die beweglichen Rollen automatisch in die bajonettartig ausgeführten Nuten 31 eingeführt und bis zum Endanschlag der Nuten 31 geführt. Aufgrund der Steigung der Nuten 31 wird, wenn die Rollen 25 des Verbindungsrings 25 sich entlang der Nuten 31 bewegen, der Lampenvorsatz 3 automatisch in Richtung des Verbindungsrings 2 und mit seinem Absatz 32 in diesen hinein bewegt, so daß eine feste und dichte Verbindung entsteht.To connect the lamp attachment 3 with the lamp housing 1, it is only necessary that the shoulder 32 of the lamp attachment 3 is inserted into the connecting ring 2. In a subsequent rotation of the connecting ring 2, the movable rollers are automatically inserted into the bayonet-shaped grooves 31 and guided to the end stop of the grooves 31. Due to the pitch of the grooves 31, when the rollers 25 of the connecting ring 25 move along the grooves 31, the lamp attachment 3 is formed automatically moves in the direction of the connecting ring 2 and with his paragraph 32 in this, so that a firm and tight connection is formed.

Durch einfaches Drehen des mit dem Lampengehäuse 1 verbundenen Verbindungsrings 2 wird somit der Lampenvorsatz automatisch mit dem Verbindungsring 2 bzw. dem Lampengehäuse 1 verbunden.Thus, by simply rotating the connecting ring 2 connected to the lamp housing 1, the lamp attachment is automatically connected to the connecting ring 2 or the lamp housing 1.

Um sicherzustellen, daß die Rollen 25 im Endanschlag der Nuten einrasten und sich nicht selbständig lösen können, sind an den Enden der Nuten gemäß Figur 6a, 6b Mulden 31a ausgebildet, in die die beweglichen Rollen 25 einrasten. Um ein sicheres Einrasten der Rollen 25 in den Mulden 31a zu gewährleisten, ist zwischen dem Lampenvorsatz und dem Lampengehäuse ein federndes Element, beispielsweise ein O-Ring (nicht dargestellt) angeordnet, der eine gewisse Druckkraft zwischen dem Lampengehäuse und dem Lampenvorsatz bereitstellt.In order to ensure that the rollers 25 engage in the end stop of the grooves and can not disengage independently, depressions 31a are formed at the ends of the grooves according to FIGS. 6a, 6b, into which the movable rollers 25 engage. In order to ensure a secure engagement of the rollers 25 in the wells 31a, a resilient element, for example an O-ring (not shown) is arranged between the lamp attachment and the lamp housing, which provides a certain compressive force between the lamp housing and the lamp attachment.

In Figur 8 ist die erfindungsgemäße Verbindungsanordnung dargestellt, nachdem der Lampenvorsatz mittels des erfindungsgemäßen Verbindungsrings mit dem Lampengehäuse 1 verbunden ist. Bei Bedarf kann in einfacher Weise ein anderer Lampenvorsatz 3 an das Gehäuse angebracht werden, indem der Verbindungsring gedreht, der Lampenvorsatz entfernt, ein neuer Lampenvorsatz in den Verbindungsring eingeführt und der Verbindungsring erneut gedreht wird.FIG. 8 shows the connection arrangement according to the invention after the lamp attachment is connected to the lamp housing 1 by means of the connecting ring according to the invention. If necessary, another lamp attachment 3 can be easily attached to the housing by turning the connection ring, removing the lamp attachment, inserting a new lamp attachment into the connection ring, and rotating the connection ring again.

Es wird darauf hingewiesen, daß in dem Lampengehäuse 1 zwei federnde Kontaktstifte vorgesehen sind, die mit einer Sicherheitsschaltung verbunden sind. Bei Verbindung des Lampengehäuses mit einem Lampenvorsatz gemäß Figur 8 treten die gefederten Kontaktstifte in Verbindung mit einer am Lampenvorsatz angeordneten Kontaktplatte, die zwei kreisrunde Kontaktbahnen aufweist, die über eine Kontaktbrücke miteinander verbunden sind. Sobald der Lampenvorsatz vom Lampengehäuse entfernt und dementsprechend die gefederten Kontaktstifte außer Kontakt mit der Kontaktplatte treten, sorgt die Sicherheitsschaltung automatisch für ein Abschalten der Lampe, um ein unerwünschtes Abstrahlen von UV-Strahlung zu verhindern. Eine derartige Sicherungsanordnung ist aus der DE-U-200 16 303.5 bekannt.It should be noted that in the lamp housing 1, two resilient contact pins are provided, which are connected to a safety circuit. When connecting the lamp housing with a lamp attachment according to Figure 8, the spring-loaded contact pins in conjunction with a arranged on the lamp attachment contact plate, the two circular Contact tracks which are interconnected via a contact bridge. Once the lamp header is removed from the lamp housing and, accordingly, the spring-loaded pins are out of contact with the contact plate, the safety circuit automatically shuts off the lamp to prevent unwanted radiation of UV radiation. Such a fuse arrangement is known from DE-U-200 16 303.5.

Stifte verwendet werden. Diese können statt an der Innenseite des Verbindungsrings alternativ auch an der Stirnseite des Verbindungsrings angebracht sein. Des weiteren können im Lampenvorsatz statt bajonettartiger Nuten beispielsweise Schlitze als Kopplungsmittel eingesetzt werden. Wesentlich für die Erfindung ist allein, daß ein Verbindungsring mit einem ersten und einem zweiten Bereich vorgesehen ist, der über den ersten Bereich mit einem ersten optischen Bauteil über den zweiten optischen Bauteil verbindbar ist, und wobei in dem zweiten Bereich Kopplungsmittel vorgesehen sind, die bei Drehen des Verbindungsrings automatisch in Eingriff mit zugeordneten Kopplungsmitteln des zweiten Bauteils gelangen.The invention is not limited in its execution to the embodiments shown above. For example, instead of rollers, other coupling parts, e.g. Pins are used. These may alternatively be attached to the end face of the connecting ring instead of on the inside of the connecting ring. Furthermore, in the lamp attachment instead of bayonet-like grooves, for example, slots can be used as a coupling agent. It is essential for the invention alone that a connecting ring is provided with a first and a second region, which is connectable via the first region with a first optical component via the second optical component, and wherein in the second region coupling means are provided at Rotate the connecting ring automatically engage with associated coupling means of the second component.
