Description

Die Erfindung bezieht sich auf einen rotationssymmetrischen Hochleistungsscheinwerfer für Halogen-Metalldampflampen ge­mäß dem Oberbegriff des Anspruches 1.The invention relates to a rotationally symmetrical high-performance headlamp for metal halide lamps according to the preamble of claim 1.

Ein rotationssymmetrischer Hochleistungsscheinwerfer für Halo­gen-Metalldampflampen der gattungsgemäßen Art ist aus der DE 30 40 583 C 2 vorbekannt. Das Auswechseln der Halogen-­Metalldampflampen nach dem Abnehmen des rückwärtigen Gehäuse­deckels ist hierbei äußerst schwierig, insbesondere bei der Anordnung des Hochleistungsscheinwerfers auf Flutlichtmasten von bis zu 50 m Höhe, da die Lampe auch bei abgenommenen Gehäuse­deckel noch unter Spannung steht, so daß die Lampe nicht ge­fahrlos gewechselt werden kann.A rotationally symmetrical high-performance headlamp for metal halide lamps of the generic type is previously known from DE 30 40 583 C 2. Replacing the metal halide lamps after removing the rear housing cover is extremely difficult, especially when arranging the high-performance headlamp on floodlight masts of up to 50 m in height, since the lamp is still live, even when the housing cover is removed, so that the lamp is not safe can be changed.

Der Erfindung liegt von daher die Aufgabe zugrunde, einen rota­ tionssymmetrischen Hochleistungsscheinwerfer für Halogen-­Metalldampflampen derart auszubilden, daß die in der Rota­tionsachse des Reflektors angeordnete und diesen in einer zentrischen Öffnung durchgreifende Halogen-Metalldampflampe leicht auswechselbar angeordnet ist.The invention is therefore based on the object of a rota tion-symmetrical high-performance headlights for metal halide lamps in such a way that the arranged in the axis of rotation of the reflector and this penetrating in a central opening metal halide lamp is arranged easily replaceable.

Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnen­den Merkmalen des Anspruches 1. Durch Verwendung des das Gehäuse rückwärtig abschließenden Gehäusedeckels, der den Lampensockel aufnimmt und mittels einer Schiebe-Kipp-Lagerung am Gehäuse abklappbar gelagert ist, ist es möglich, die Halogen-Metalldampflampe in einfacher Weise von der rück­wärtigen Seite des Hochleistungsscheinwerfers her auszu­wechseln,welche insbesondere bei Anordnung von Hochleistungs­scheinwerfern an bis zu 50 m hohen Flutlichtmasten gut zugänglich ist. Die Schiebe-Kipp-Lagerung ermöglich einerseits, daß dice in der Rotationsachse des Reflektors befindliche Halogen-Metalldampflampe zunächst mittels des Gehäusedeckels um einen bestimmten Bereich aus dem Reflektor nach rückwärts herausgezogen wird, welcher Bereich gerade ausreichend ist, um anschließend ein Abklappen des Gehäusedeckels zusammen mit der Halogen-Metalldampflampe zu ermöglichen, ohne daß diese dann gegen die Randbereiche der zentralen Öffnung des Re­flektors stößt. Nach dem Abklappen des Gehäusedeckels ist die Halogen-Metalldampflampe leicht auswechselbar. In gleicher Weise kann der Gehäusedeckel dann mit der neuen Halogen-­Metalldampflampe zunächst hochgeklappt und anschließend wieder auf die rückwärtige Seite des Gehäuses des Hochleistungs­scheinwerfers aufgeschoben werden, wobei die Halogen-Metall­dampflampe in der Rotationsachse des Reflektors axial ver­schoben wird.The solution to this problem results from the characterizing features of claim 1. By using the housing cover closing the rear of the housing, which receives the lamp base and is hinged on the housing by means of a slide-tilt mounting, it is possible to in the metal halide lamp easy to replace from the rear side of the high-performance headlamp, which is particularly accessible when high-performance headlamps are installed on floodlight masts up to 50 m high. The slide-tilt mounting allows on the one hand that the metal halide lamp located in the axis of rotation of the reflector is first pulled backwards out of the reflector by a certain area by means of the housing cover, which region is just sufficient to then fold the housing cover together with to enable the metal halide lamp, without this then hitting the edge areas of the central opening of the reflector. After the housing cover has been folded down, the metal halide lamp can be easily replaced. In the same way, the housing cover with the new metal halide lamp can first be folded up and then pushed back onto the rear side of the housing of the high-performance headlight, the metal halide lamp being axially displaced in the axis of rotation of the reflector.

Es ist zwar bereits ein rotationssymmetrischer Hochleistungs­scheinwerfer für Halogen-Metalldampflampen bekannt, welcher einen rückwärtigen Gehäusedeckel aufweist, der abklappbar am Gehäuse gelagert ist. Hierbei ist die Halogen-Metalldampf­lampe jedoch quer zur Rotationsachse des Reflektors eingebaut und im Gehäusedeckel gesockelt. Dies bedingt einen zweige­teilten Reflektor, dessen zentraler Teil am Gehäusedeckel selbst hinter der Halogen-Metalldampflampe angeordnet ist und zusammen mit dem Gehäusedeckel abgeklappt wird, wohin­gegen der übrige, kreis-ringförmige Teil des Reflektors im Gehäuse angeordnet ist. Hierbei wird der Gehäusedeckel um eine untere, horizontale Achse geklappt. Nachteilig hier­bei ist, daß die beiden, Molybdän-Folien enthaltenden Enden der Halogen-Metalldampflampe Rückstrahlungen vom Reflektor erhalten, da beide Enden innerhalb des Reflektors angeordnet sind. Diese Wärmestrahlungen bewirken eine Zerstörung der Molybdänfolien an beiden Enden der Lampe.A rotationally symmetrical high-performance headlight for metal halide lamps is already known, which has a rear housing cover which is mounted on the housing so that it can be folded down. However, the metal halide lamp is installed transversely to the axis of rotation of the reflector and socketed in the housing cover. This requires a two-part reflector, the central part of which is arranged on the housing cover itself behind the metal halide lamp and is folded down together with the housing cover, whereas the remaining circular part of the reflector is arranged in the housing. Here, the housing cover is folded around a lower, horizontal axis. The disadvantage here is that the two ends of the metal halide lamp containing molybdenum foils receive reflections from the reflector, since both ends are arranged within the reflector. This heat radiation destroys the molybdenum foils at both ends of the lamp.

Demgegenüber befindet sich die Halogen-Metalldampflampe beim erfindungsgemäßen rotationssymmetrischen Hochleistungsschein­werfer in der Rotationsachse des Reflektors, wobei nur ein einteiliger Reflektor mit einer kleinen zentralen Lochöffnung erforderlich ist. Der einteilige Reflektor hat einen höchst­möglichen Wirkungsgrad, da in der Hauptlichtverteilung der Lampe eine 100%ige Bündelung der Lichtstrahlung möglich ist. Beide Molybdän-Folien der Lampenenden erhalten keine Rück­strahlungen vom Reflektor, da das hintere Ende der Lampe außerhalb des Reflektors im rückwärtigen Gehäusedeckel und das vordere Ende der Lampe im großen Öffnungsbereich des Reflektors angeordnet sind, wobei Licht- und Wärmestrahlung parallel an den Molybdäm-Folien-Quetschstellen vorbeigeführt werden, ohne eine Aufheizung zu bewirken.In contrast, the metal halide lamp in the rotationally symmetrical high-performance headlamp according to the invention is located in the axis of rotation of the reflector, only a one-piece reflector with a small central hole opening being required. The one-piece reflector has the highest possible degree of efficiency, since a 100% concentration of the light radiation is possible in the main light distribution of the lamp. Both molybdenum foils of the lamp ends receive no reflections from the reflector, since the rear end of the lamp is arranged outside the reflector in the rear housing cover and the front end of the lamp in the large opening area of the reflector, with light and heat radiation parallel to the molybdenum foil Squeeze points passed without causing heating.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Diese betreffen einerseits die bevorzugte Ausgestaltung der erfindungsgemäßen Schiebe-­Kipplagerung des Gehäusedeckels und andererseits die An­ordnung eines mit dem Lampensockel elektrisch verbundenen Steckers am Gehäusedeckel sowie einer Steckbuchse am Ge­häuse im Bereich der Gehäuseöffnung, wobei diese Steck­buchse an die elektrische Zuleitung angeschlossen ist. Beim Ziehen bzw. Schieben des rückwärtigen Gehäusedeckels werden zugleich mit dem axialen Herausziehen der Halogen-­Metalldampflampe aus dem Reflektor die Steckkontakte des Steckers aus der gehäusefesten Steckbuchse herausgezogen, so daß bereits vor dem Abklappen des Gehäusedeckels jeg­liche elektrische Verbindung zwischen dem Lampensockel und der elektrischen Zuleitung zum Halogen-Hochleistungs­scheinwerfer unterbrochen ist. Hierdurch wird eine unfall­sichere Möglichkeit zum Auswechseln der Halogen-Metall­dampflampe von bis zu 2000 Watt geschaffen, da die Lampe und deren Lampensockelteile nach dem Herausziehen des rück­wärtigen Gehäusedeckels keine Spannung mehr führen können.Further advantageous embodiments of the invention result from the subclaims. These relate on the one hand to the preferred embodiment of the slide-tilt bearing of the housing cover according to the invention and on the other hand to the arrangement of a plug on the housing cover which is electrically connected to the lamp base and a socket on the housing in the region of the housing opening, this socket being connected to the electrical supply line. When pulling or pushing the rear housing cover, the plug contacts of the plug are pulled out of the housing-fixed socket at the same time as the metal halide lamp is pulled axially out of the reflector, so that any electrical connection between the lamp base and the electrical supply line is already opened before the housing cover is folded down Halogen high-performance headlights is interrupted. This creates an accident-proof possibility of replacing the metal halide lamp of up to 2000 watts, since the lamp and its lamp base parts can no longer carry any voltage after the rear housing cover has been pulled out.

Bei dem bekannten Hochleistungsscheinwerfer mit abklappbarem Gehäusedeckel sind ein Schalter und ein Kontaktstück zwischen Gehäuseöffnung und Gehäusedeckel angeordnet. Dies bedingt ein Schaltschütz, um die über die Zuleitung zugeführte Spannung abzuschalten, damit die Metalldampflampe spannungs­los wird. Das Schaltschütz sitzt regelmäßig außerhalb des Scheinwerfers und bedingt demzufolge eine separate Zuleitung. Zur Wartung muß die Zuleitung vom Gehäusedeckel elektrisch ab­geklemmt werden, um die Hochspannungseinrichtungen des Hochleistungsscheinwerfers zu warten. Demgegenüber kann beim erfindungsgemäßen Hochleistungsscheinwerfer der rück­wärtige Gehäusedeckel nach dem Herausziehen und Abklappen ohne weitere Tätigkeiten vom Gehäuse abgenommen und zu Wartungsarbeiten vom Hochleistungsscheinwerfer entfernt werden.In the known high-performance headlamp with a hinged housing cover, a switch and a contact piece are arranged between the housing opening and the housing cover. This requires a contactor to switch off the voltage supplied via the supply line so that the metal halide lamp is de-energized. The contactor is regularly outside the headlight and therefore requires a separate supply line. For maintenance, the supply line must be electrically disconnected from the housing cover to the high-voltage devices of the High performance headlights to maintain. In contrast, in the high-performance headlamp according to the invention, the rear housing cover can be removed from the housing after being pulled out and folded down without further activities and removed from the high-performance headlamp for maintenance work.

Der rotationssymmetrische Hochleistungsscheinwerfer für eine Halogen-Metalldampflampe 1 umfaßt ein kegelstumpfförmiges Gehäuse 2, einen darin angeordneten parabolischen Reflektor 3, eine vordere Abdeckscheibe 4, einen rückwärtigen Gehäusedeckel 5 und einen darin befestigten Lampensockel 6 für die Lampe 1. Diese weist einen Lampenkolben 7 und zwei Molybdän-Folien enthaltende dünne Lampenenden 8, 9 auf, von denen das rück­wärtige Lampenende 8 unmittelbar in den Lampensockel 7 ein­gesteckt ist und das vordere, zur Abdeckscheibe 4 hinwei­sende Lampenende 9 an einem Stromzuführungsstab 10 gehalten ist, der ebenfalls im Lampensockel 6 gelagert ist.
Die Lampe 1 ist mit ihrer Längsachse in der Rotationsachse 11 des Gehäuses 2 und des Reflektors 3 angeordnet und durch­dringt den Reflektor 3 am rückwärtigen Ende innerhalb einer Öffnung 12, die gerade so groß ist, daß die Lampe 1 zu­sammen mit dem Stromzuführungsstab 10 in Richtung der Ro­tationsachse 11 hindurchgesteckt werden kann.The rotationally symmetrical high-performance headlamp for a metal halide lamp 1 comprises a truncated cone-shaped housing 2, a parabolic reflector 3 arranged therein, a front cover plate 4 and a rear housing cover 5 and a lamp base 6 fastened therein for the lamp 1. This has a lamp bulb 7 and two thin lamp ends 8, 9 containing molybdenum foils, of which the rear lamp end 8 is inserted directly into the lamp base 7 and the front end, pointing towards the cover plate 4 Lamp end 9 is held on a power supply rod 10, which is also mounted in the lamp base 6.
The lamp 1 is arranged with its longitudinal axis in the axis of rotation 11 of the housing 2 and the reflector 3 and penetrates the reflector 3 at the rear end within an opening 12 which is just large enough that the lamp 1 together with the power supply rod 10 in the direction of Rotation axis 11 can be inserted.

Das kegelstumpfförmige, rotationssymmetrische Gehäuse 2 umfaßt einen zylindrischen Endbereich 13, an den der ent­sprechend zylindrisch ausgebildete rückwärtige Gehäuse­deckel 5 abgedichtet angesetzt ist. Der Endbereich 13 trägt in der horizontalen Querachse zwei Schwenklager 14, mit welchen das Gehäuse 2 an den Armen 15 eines Befestigungs­gungsbügels gelagert ist.The frustoconical, rotationally symmetrical housing 2 comprises a cylindrical end region 13 to which the correspondingly cylindrical rear housing cover 5 is attached in a sealed manner. The end region 13 carries in the horizontal transverse axis two pivot bearings 14, with which the housing 2 is mounted on the arms 15 of a fastening bracket.

Eine nicht näher dargestellte elektrische Zuleitung ist durch eine Öffnung 16 im Endbereich 13 hindurchgeführt und dann im Gehäuse 2 im Bereich der rückwärtigen Gehäuse­öffnung 17 für den Gehäusedeckel 5 an eine Steckbuchse 18 angeschlossen. In die Steckbuchse 18 ist ein Stecker 19 mit seinen Steckerstiften 20 eingesteckt, welche mit den An­schlußkontakten für die Lampe 1 im Lampensockel 6 innerhalb des Gehäusedeckels 5 elektrisch verbunden sind.An electrical lead, not shown, is passed through an opening 16 in the end region 13 and then connected to a socket 18 in the housing 2 in the region of the rear housing opening 17 for the housing cover 5. In the socket 18, a plug 19 is inserted with its connector pins 20, which are electrically connected to the contacts for the lamp 1 in the lamp base 6 within the housing cover 5.

Der rückwärtige Gehäusedeckel 5 ist mittels zwei in der Ebene der Schwenklager 14 gelegenen Verschlüssen 21 am Gehäuse 2 festgelegt und kann nach dem Abklappen der Verschlüsse 21 (Fig.4) mittels einer Schiebe-Kipplagerung 22 vom Gehäuse 2 abgeklappt werden. Hierzu sind in der Ebene der Schwenkla­ger 14 im Bereich der Verschlüsse 21 Lagerstifte 23 in die zum Gehäuse 2 gerichtete Stirnseite des Gehäusedeckels 5 eingesetzt, wobei die Lagerstifte 23 parallel zur Rotations­achse 11 verlaufen und in Steckbuchsen 24 eingreifen, die in der rückwärtigen Stirnseite der Gehäuseöffnung 17 aus­gebildet sind (Fig.4). Parallel zu den Lagerstiften 23 und zur Rotationsachse 11 sind die Steckerstifte 20 des Steckers 19 im Gehäusedeckel 5 angeordnet, wobei die Steckerstifte 20 in entsprechend ausgerichtete Kontaktklemmen der Steckbuchse 18 eingreifen, die in der Gehäuseöffnung 17 angeordnet ist. Die Schiebe-Kipplagerung 22 umfaßt ferner zwei auf der Unter­seite des Gehäusedeckels 5 fest angebrachte abgewinkelte Scharnierarme 25, welche an ihren freien Enden parallele Scharnierteile 26 aufweisen, die mit Langlöchern 27 versehen sind. Die Scharnierteile 26 und die Langlöcher 27 verlaufen parallel zur Rotationsachse 11 und damit zu den Lagerstiften 23, jedoch in einem radialen Abstand, der größer ist, als der halbe Radius des Gehäusedeckels 5. Im unteren Bereich des Gehäuses 2 sind Führungen 28 für die Scharnierteile 26 vor­gesehen, welche Führungen 28 am rückwärtigen Teil Lagerbolzen 29 tragen, welche in die Langlöcher 27 der Scharnierteile 26 eingreifen. Die Oberseiten 30 der Führungen 28 dienen zur gieitbaren Anlage der Scharnierteile 26.The rear housing cover 5 is in the plane by means of two the locks 21 located on the pivot bearing 14 are fixed to the housing 2 and, after the locks 21 (FIG. 4) have been folded down, can be folded away from the housing 2 by means of a slide-tilt bearing 22. For this purpose, bearing pins 23 are inserted in the plane of the pivot bearing 14 in the area of the closures 21 into the end face of the housing cover 5 directed towards the housing 2, the bearing pins 23 running parallel to the axis of rotation 11 and engaging in sockets 24 which engage in the rear end face of the housing opening 17 are trained (Fig.4). The connector pins 20 of the connector 19 are arranged in the housing cover 5 parallel to the bearing pins 23 and to the axis of rotation 11, the connector pins 20 engaging in correspondingly aligned contact terminals of the socket 18 which is arranged in the housing opening 17. The slide-tilt bearing 22 further comprises two angled hinge arms 25 fixedly attached to the underside of the housing cover 5, which have parallel hinge parts 26 at their free ends, which are provided with elongated holes 27. The hinge parts 26 and the elongated holes 27 run parallel to the axis of rotation 11 and thus to the bearing pins 23, but at a radial distance which is greater than half the radius of the housing cover 5. In the lower region of the housing 2 there are guides 28 for the hinge parts 26 provided which guides 28 on the rear part carry bearing pins 29 which engage in the elongated holes 27 of the hinge parts 26. The upper sides 30 of the guides 28 serve for the sliding contact of the hinge parts 26.

Zum Auswechseln der Lampe 1 muß der rückwärtige Gehäusedeckel 5 vom Gehäuse 2 abgenommen werden. Hierzu werden zunächst die beiden in der Ebene der Schwenklager 14 gelegenen Verschlüsse 21 vom Gehäusedeckel 5 gelöst, wie es in Fig.4 dargestellt ist. Anschließend wird der Gehäusedeckel 5 in Richtung des Pfeiles 31 (Fig.3) nach rückwärts gezogen, wobei die in den Steckbuchsen 24 geführten Lagerstifte 23 des Gehäuse­deckels 5 eine parallele Führung des Gehäusedeckels 5 in der Richtung der Rotationsachse 11 erzwingen, so daß die Lampe 1, die in ihrer Endlage innerhalb des Reflek­tos 3 befindlich ist (Fig.1), mit ihrer im Querschnitt dicksten Stelle vollständig aus der Öffnung 12 des Re­flektors 3 nach rückwärts herausgezogen ist. Gleichzeitig mit dem Abziehen des Gehäusedeckels 5 vom Gehäuse 2 werden die Steckerstifte 20 des Steckers 19 aus den zuge­ordneten Kontakten der Steckbuchse 18 herausgezogen, wie es in Fig.3 dargestellt ist. Während des gesamten Schiebe­vorganges des Gehäusedeckels 5 werden die Oberkanten der Scharnierteile 26 an den Oberseiten 30 der Führungen 28 entlanggeführt, solange, bis die Lagerbolzen 29 am Ende der Langlöcher 27 angekommen sind (Fig.3). Nunmehr kann der Gehäusedeckel 5 gemäß Fig. 5 in Richtung des Dreh­pfeiles 32 vom Gehäuse 2 abgeklappt werden, wobei die Lager­bolzen 29 als Drehachse für den Gehäusedeckel 5 dienen. Das vorderste, mit dem Ende des Stromführungsstabes 10 verbundene Lampenende 9 der Lampe 1 wird dabei auf einem Radius geführt, der in Fig. 5 mit den gestrichelten Linien 33 dargestellt ist, die gerade noch innerhalb der rückwärti­gen Öffnung 12 des Reflektors 3 liegen. Die Lampe 1 kann nunmehr leicht ausgewechselt werden, wobei bereits vor der rückwärtigen Endstellung des Gehäusedeckels 5 gemäß Fig. 3 die elektrische Stromzuführung zum Lampensockel 6 getrennt worden ist, so daß die Lampe 1 vollständig spannungslos ist. Das Wiedereinsetzen der Lampe 1 erfolgt in umgekehrter Weise durch Einschwenken der Lampe 1 in das Gehäuse und durch axiales Aufschieben des Gehäusedeckels 5 auf das Gehäuse 2 unter gleichzeitiger Herstellung der elektrischen Ver­bindung zwischen Steckbuchse 18 und Stecker 19 und anschließendem Verriegeln des Gehäusedeckels 5 mittels der Verschlüsse 21.To replace the lamp 1, the rear housing cover 5 must be removed from the housing 2. For this purpose, the two closures 21 located in the plane of the pivot bearings 14 are first released from the housing cover 5, as shown in FIG. The housing cover 5 is then pulled backwards in the direction of the arrow 31 (FIG. 3), the bearing pins 23 of the housing cover 5 guided in the sockets 24 forcing the housing cover 5 to be guided in the direction of the axis of rotation 11 in parallel, so that the lamp 1 , which is located in its end position inside the reflector 3 (FIG. 1), with its thickest section in cross section, is completely pulled out of the opening 12 of the reflector 3 to the rear. Simultaneously with the removal of the housing cover 5 from the housing 2, the plug pins 20 of the plug 19 are pulled out of the associated contacts of the socket 18, as shown in FIG. During the entire sliding process of the housing cover 5, the upper edges of the hinge parts 26 are guided along the upper sides 30 of the guides 28 until the bearing bolts 29 have reached the end of the elongated holes 27 (FIG. 3). 5 can now be folded down in the direction of the arrow 32 from the housing 2, the bearing bolts 29 serving as the axis of rotation for the housing cover 5. The foremost lamp end 9 of the lamp 1, which is connected to the end of the current carrying rod 10, is guided on a radius which is shown in FIG. 5 with the dashed lines 33 which are just inside the rear opening 12 of the reflector 3. The lamp 1 can now be easily replaced, the electrical power supply to the lamp base 6 having been disconnected even before the rear end position of the housing cover 5 according to FIG. 3, so that the lamp 1 is completely dead. The lamp 1 is reinserted in the opposite manner by pivoting the lamp 1 into the housing and by axially pushing the housing cover 5 onto the housing 2 while simultaneously establishing the electrical connection between socket 18 and plug 19 and then locking the housing cover 5 by means of the closures 21.
