Description

Die Erfindung bezieht sich auf eine Hochdruckentladungslampe mit einem in einem Außenkolben drehbar gelagerten und senkrecht angeordneten Entladungsgefäß.The invention relates to a high-pressure discharge lamp with a discharge vessel which is rotatably mounted and arranged vertically in an outer bulb.

Hochdruckentladungslampen, z.B. Quecksilber-Hochdrucklampen, Natriumhochdrucklampen und insbesondere Quecksilber-Hochdrucklampen mit Zusätzen von Metallen, vorzugsweise in Form von Metallhalogeniden, ändern ihre lichttechnischen Eigenschaften, wenn ihre Brennlage geändert wird. Dies wirkt sich besonders stark aus, wenn die Lampen mit Gleichstrom oder pulsierendem Gleichstrom betrieben werden. In diesem Fall führt eine Änderung der Brennlage von der senkrechten zur waagerechten Stellung zu besonders großen Unterschieden der Farbtemperatur und damit der Farbwiedergabeeigenschaften.High pressure discharge lamps, e.g. High-pressure mercury lamps, high-pressure sodium lamps and in particular high-pressure mercury lamps with additions of metals, preferably in the form of metal halides, change their lighting properties when their burning position is changed. This has a particularly strong effect if the lamps are operated with direct current or pulsating direct current. In this case, a change in the burning position from the vertical to the horizontal position leads to particularly large differences in the color temperature and thus the color rendering properties.

Aus der JA-OS 56-63763 (1981) ist eine Metallhalogenid-Hochdruckentladungslampe bekannt, deren Entladungsgefäß zur Erzielung einer senkrechten Brennlage um eine senkrecht zur Lampenachse angeordnete waagerechte Achse drehbar ist. Um diese Achse waagerecht zu halten, kann die Lampe zwar in einer Ebene geschwenkt, darf aber nicht um ihre Längsachse gedreht werden. Die Stellung der Lampe ist somit nicht völlig frei wählbar. Die Stromzuführung zum Entladungsgefäß erfolgt bei der bekannten Lampe darüber hinaus über spiralförmig gewickelte Drähte, wodurch die Drehbarkeit des Entladungsgefäßes um ihre Drehachse behindert wird.A metal halide high-pressure discharge lamp is known from JA-OS 56-63763 (1981), the discharge vessel of which can be rotated about a horizontal axis arranged perpendicular to the lamp axis in order to achieve a vertical burning position. In order to keep this axis horizontal, the lamp can be swiveled in one plane, but must not be rotated around its longitudinal axis. The position of the lamp is therefore not completely free to choose. In the known lamp, the current supply to the discharge vessel also takes place via spirally wound wires, whereby the rotatability of the discharge vessel about its axis of rotation is hindered.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Hochdruckentladungslampe zu schaffen, deren Entladungsgefäß in jeder Stellung der Lampe immer die senkrechte Brennlage einnimmt, wobei die Drehbarkeit des Entladungsgefäßes nicht durch die Stromzuführungsdrähte oder dergl. behindert wird.The invention is therefore based on the object of providing a high-pressure discharge lamp whose discharge vessel always assumes the vertical burning position in any position of the lamp, the rotatability of the discharge vessel not being impeded by the power supply wires or the like.

Diese Aufgabe wird bei einer Hochdruckentladungslampe eingangs erwähnter Art gemäß der Erfindung dadurch gelöst, daß das Entladungsgefäß im Außenkolben kardanisch aufgehängt ist und die Stromzuführung zum Entladungsgefäß über die kardanische Aufhängung erfolgt.This object is achieved in a high-pressure discharge lamp of the type mentioned at the outset according to the invention in that the discharge vessel is gimbaled in the outer bulb and the current supply to the discharge vessel takes place via the gimbal suspension.

Durch die kardanische Aufhängung behält das Entladungsgefäß bei unterschiedlicher Stellung der Lampe immer seine senkrechte Lage bei. Da die Stromzuführung zum Entladungsgefäß über die kardanische Aufhängung selbst erfolgt, erübrigen sich zusätzliche Stromzuführungsdrähte.Due to the cardanic suspension, the discharge vessel always maintains its vertical position when the lamp is in different positions. Since the current supply to the discharge vessel takes place via the cardanic suspension itself, there is no need for additional current supply wires.

Zur Verbesserung der Kontaktgabe sind gemäß einer Weiterbildung nach der Erfindung an den Lagerstellen der beiden Drehachsen der kardanischen Aufhängung zusätzliche Schleifkontakte vorgesehen.To improve the contact, according to a development according to the invention, additional sliding contacts are provided at the bearing points of the two axes of rotation of the gimbal.

Der Außenkolben von miniaturisierten Hochdruckentladungslampen hat praktisch die Form einer üblichen Glühlampe. Um in einem derartig kleinen Außenkolben ein Entladungsgefäß mit einer kardanischen Aufhängung unterbringen zu können, müssen dessen Abmessungen entsprechend klein gehalten werden. Dies läßt sich zweckmäßigerweise noch dadurch verbessern, daß die die Elektrodendurchführungen umgebenden Enden des Entladungsgefäßes aus der Gefäßachse herausgebogen sind, wodurch sich die Gesamtlänge des Entladungsgefäßes verringert.The outer bulb of miniaturized high-pressure discharge lamps practically has the shape of a conventional incandescent lamp. In order to be able to accommodate a discharge vessel with a cardanic suspension in such a small outer bulb, its dimensions must be kept correspondingly small. This can expediently be further improved in that the ends of the discharge vessel surrounding the electrode bushings are bent out of the vessel axis, as a result of which the overall length of the discharge vessel is reduced.

Ein Ausführungsbeispiel einer Hochdruckentladungslampe nach der Erfindung wird nunmehr anhand der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 den Innenaufbau einer Hochdruckentladungslampe in Seitenansicht, wobei der Außenkolben übersichtshalber fortgelassen wurde, und
  • Fig. 2 einen Längsschnitt durch eine Hochdruckentladungslampe mit einem Innenaufbau nach Fig. 1 in Schrägstellung.
An embodiment of a high-pressure discharge lamp according to the invention will now be explained in more detail with reference to the drawing. Show it:
  • F ig. 1 shows the internal structure of a high-pressure discharge lamp in a side view, the outer bulb having been omitted for the sake of clarity, and
  • F ig. 2 shows a longitudinal section through a high-pressure discharge lamp with an internal structure according to FIG. 1 in an inclined position.

Bei der dargestellten Hochdruckentladungslampe sind zwei Poldrähte 1 und 2 in eine Glasquetschung 30 eingeschmolzen und führen zu einem in der Zeichnung nicht dargestellten Lampensockel. Mit den inneren Enden der Poldrähte 1 und 2 sind zwei viertelkreisförmige Drahtstücke 3 und 4, z.B. durch Schweißen, verbunden, die einen sog. Kardanring für einen ringförmigen Rahmen 5 bilden. Hierfür sind die viertelkreisförmigen Drahtstücke 3 und 4 mit jeweils einem Rahmenlager 6 bzw. 7 versehen, welche zur Aufnahme der Rahmenachsen 8 bzw. 9 des Rahmens 5 dienen. Die beiden Rahmenachsen 8 und 9 bilden die erste Drehachse A-A einer kardanischen Aufhängung.In the high-pressure discharge lamp shown, two pole wires 1 and 2 are melted into a glass pinch 30 and lead to a lamp base, not shown in the drawing. With the inner ends of the pole wires 1 and 2 are two quarter-circular wire pieces 3 and 4, e.g. by welding, which form a so-called gimbal for an annular frame 5. For this purpose, the quarter-circular wire pieces 3 and 4 are each provided with a frame bearing 6 and 7, which serve to receive the frame axes 8 and 9 of the frame 5. The two frame axes 8 and 9 form the first axis of rotation A-A of a gimbal.

Der ringförmige Rahmen 5 ist an zwei Stellen unterbrochen und dort durch ein Isoliermaterial, z.B. eine Glasperle 10, ersetzt. Um 900 gegenüber der Drehachse A-A versetzt, sind am Rahmen 5 zwei Lauflager 11 und 12 angebracht, welche zur Aufnahme von Laufachsen 13 und 14 dienen, welche die zweite Drehachse B-B der kardanischen Aufhängung bilden. Auf die beiden Laufachsen 13 und 14 ist jeweils ein Ausleger 15 bzw. 16 aufgesetzt. An die Enden dieser Ausleger 15 und 16 sind Molybdän/Wolfram-Durchführungen 17 und 18 einer kleinen Metallhalogenid-Hochdruckentladungslampe 19 angeschlossen, deren z.B.aus Quarzglas bestehendes Entladungsgefäß mit 20 bezeichnet ist. Zur Verkleinerung der Abmessungen sind die die Elektrodendurchführungen 17 und 18 umgebenden Enden 21 und 22 des Entladungsgefäßes 20 aus der Gefäßachse rechtwinklig nach entgegengesetzten Seiten abgebogen. Zur Erzielung einer senkrechten Brennlage der Lampe 19 ist diese an der unteren Elektrodendurchführung 22 mit einem Gewicht 23 beschwert. Die Lampe 19 ist somit um die beiden Drehachsen A-A und B-B drehbar gelagert, und zwar so, daß sie bei jeder Stellung der mit einem Außenkolben 24 versehenen Hochdruckentladungslampe immer eine senkrechte Brennlage einnimmt, wie aus Fig. 2 hervorgeht. Der Außenkolben 24 weist vorzugsweise die Form eines normalen Glühlampenkolbens auf.The ring-shaped frame 5 is interrupted at two points and replaced there by an insulating material, for example a glass bead 10. Offset by 90 ° with respect to the axis of rotation AA, two running bearings 11 and 12 are attached to the frame 5, which serve to accommodate running axes 13 and 14, which form the second axis of rotation BB of the gimbal. A boom 15 or 16 is placed on each of the two running axles 13 and 14. At the ends of these brackets 15 and 16, molybdenum / tungsten bushings 17 and 18 of a small metal halide high-pressure discharge lamp 19 are connected, the discharge vessel of which, for example, is made of quartz glass and is designated by 20 is. To reduce the dimensions, the ends 21 and 22 of the discharge vessel 20 surrounding the electrode bushings 17 and 18 are bent at right angles to opposite sides from the axis of the vessel. To achieve a vertical burning position of the lamp 19, this is weighted on the lower electrode bushing 22 with a weight 23. The lamp 19 is thus rotatably mounted about the two axes of rotation AA and BB, in such a way that it always assumes a vertical burning position in any position of the high-pressure discharge lamp provided with an outer bulb 24, as can be seen from FIG. 2. The outer bulb 24 preferably has the shape of a normal incandescent bulb.

Die Stromzuführung zur Lampe 19 erfolgt über die kardanische Aufhängung selbst, deren sämtliche Teile aus Metall bestehen. Damit in den Rahmen- und Lauflagern 6, 7 bzw. 11 und 12 keine Funkenerosion auftritt, sind an den beiden Drahtstücken 3 und 4 sowie an den beiden Drahtteilen des Rahmens 5 Schleifkontakte 25, 26, 27 und 28 befestigt, die mit ihren Enden federnd an den Rahmenachsen 8 und 9 sowie den Laufachsen 13 und 14 anliegen.

Figure imgb0001
The power supply to the lamp 19 takes place via the gimbal itself, all parts of which are made of metal. So that no spark erosion occurs in the frame and barrel bearings 6, 7 or 11 and 12, 5 sliding contacts 25, 26, 27 and 28 are attached to the two wire pieces 3 and 4 and on the two wire parts of the frame, the ends of which are resilient rest on the frame axes 8 and 9 and the running axes 13 and 14.
