Description

Gegenstand der vorliegenden Erfindung ist eine Brennpunktverstellung eines Leuchtmittels in einem Gehäuse nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a focus adjustment of a light source in a housing according to the preamble of patent claim 1.

Eine derartige Brennpunktverstellung ist bereits mit der FR-A-2 369 500 bekannt geworden. Hier ist bereits eine Fokussierung durch eine Verschiebung des Leuchtmittels in Richtung seiner Längsachse vorgesehen. Die Verstellung erfolgt hierbei mittels einer Gewindeschraube.Such a focus adjustment is already known from FR-A-2 369 500. Focusing is already provided here by shifting the illuminant in the direction of its longitudinal axis. The adjustment is made using a threaded screw.

Um nun eine Verdrehung der Lampe im Gehäuse zu verhindern, ist gemäß dieser Druckschrift eine unrunde Gehäuseform vorgesehen, so daß nur geringes Verdrehen der Lampe mit der daran befestigten Platte möglich ist. Abgesehen von dieser zwingenden Vorgabe ist darüber hinaus die Handhabung des Drehknopfs schwierig. dieser Drehknopf ist bei der FR-A-2 369 500 etwa in der Mitte des Gehäuses angebracht und so eventuell von verschiedenen Anbauteilen überdeckt.In order to prevent rotation of the lamp in the housing, a non-circular housing shape is provided according to this document, so that only slight rotation of the lamp with the plate attached to it is possible. Apart from this mandatory requirement, the handling of the rotary knob is also difficult. this knob is attached to the FR-A-2 369 500 approximately in the middle of the housing and may be covered by various attachments.

Im weiteren ist es inbesondere bei Leuchtengehäusen zur Verwendung mit Niedervolt-Halogenleuchten bekannt, den Brennpunkt derart zu verstellen, daß der Reflektor durch einen entsprechenden Verdrehantrieb verstellt wird. Hierbei ist der Reflektor beispielsweise in einem Steilgewinde im Gehäuse gehalten und durch Drehung des Reflektors wird somit der Abstand des Leuchtmittels zu der Reflektorinnenwand verstellt. Nachteil dieser bekannten Verstellung ist, daß die Verstellung nur unter relativ großem Aufwand erfolgt, denn die lichtlenkenden Mittel am Ausgang des Reflektors müssen in der Regel demontiert werden. Zudem ist mit dieser bekannten Lösung ein höherer konstruktiver Aufwand verbunden. Weiterer Nachteil ist, daß die Verstellung des Reflektors nur unter großer Wärmebelastung der Hand vonstatten gehen kann, was mit einer evtl. Verletzungsgefahr verbunden ist. Ferner besteht der Nachteil, daß man nicht den Brennpunkt bei Inbetrieb genommenem Leuchtmittel einstellen kann, denn in der Regel verdeckt die den Reflektor verstellende Hand den Lichtaustritt, so daß man nicht die Wirkung der Brennpunktverstellung sofort kontrollieren kann.Furthermore, it is known, in particular in the case of luminaire housings for use with low-voltage halogen luminaires, to adjust the focal point in such a way that the reflector is adjusted by a corresponding rotary drive. Here, the reflector is held, for example, in a steep thread in the housing and the distance of the illuminant from the inner wall of the reflector is thus adjusted by rotating the reflector. The disadvantage of this known adjustment is that the adjustment takes place only with relatively great effort, since the light-guiding means at the exit of the reflector generally have to be dismantled. In addition, this known solution is associated with a higher design effort. Further The disadvantage is that the adjustment of the reflector can only take place under high heat loads on the hand, which is associated with a possible risk of injury. There is also the disadvantage that it is not possible to adjust the focal point when the illuminant is put into operation, because the hand that adjusts the reflector usually hides the light exit, so that the effect of the focal point adjustment cannot be checked immediately.

Im übrigen muß bei einer derartig bekannten Verstellung ein Steilgewinde an der Innenseite des Leuchtengehäuses angeordnet werden, was insgesamt zu einem vergrößerten Außendurchmesser des Leuchtengehäuses führt. Damit ist auch eine aufwendigere Herstellung verbunden.Moreover, a steep thread must be arranged on the inside of the lamp housing in such a known adjustment, which leads overall to an enlarged outer diameter of the lamp housing. This also involves a more complex production.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Verstellung für ein Leuchtmittel der eingang genannten Art so weiterzubilden, daß bei geringeren Herstellungskosten eine einfachere und eine besser zugänglichere Verstellmöglichkeit für das Leuchtmittel gegeben ist.The invention is therefore based on the object of developing an adjustment for a lamp of the type mentioned in such a way that, at lower production costs, there is a simpler and more accessible adjustment option for the lamp.

Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruchs 1 gekennzeichnet.To achieve the object, the invention is characterized by the technical teaching of claim 1.

Wesentliches Merkmal der Erfindung ist, daß der Hubantrieb für die Verstellung der Fassungsplatte als Verstellhebel und/oder Kulissenführung ausgebildet ist, welcher sich mit mindestens einer Exzenterkurve an der Fassungsplattte abstützt.An essential feature of the invention is that the lifting drive for the adjustment of the mounting plate is designed as an adjusting lever and / or link guide, which is supported on the mounting plate with at least one eccentric curve.

Mit der Verdrehung des Verstellhebels, der bevorzugt exzenterisch gelagert ist, kann somit der Abstand der Fassung weiter zu dem feststehenden Reflektor leicht eingestellt werden. Die Fassungsplatte zeigt hierbei die Fassung und das Leuchtmittel.With the rotation of the adjusting lever, which is preferably mounted eccentrically, the distance between the holder and the fixed reflector can thus be easily adjusted. The socket plate shows the socket and the lamp.

Vorteilhaft hierbei ist, daß durch die erfindungsgemäße Ausbildung des Hubantriebs eine schnellere, einfachere und genauere Justierung als bei den bisher bekannten Einrichtungen möglich ist. Darüber hinaus kann durch diese Art der Konstruktion der Betätigungspunkt für den Hubantrieb von der Mitte des Gehäuses weg nach außen verlegt werden. Die Bedienung wird somit insgesamt erleichtert.The advantage here is that the inventive design of the Stroke drive a faster, easier and more accurate adjustment than is possible with the previously known devices. In addition, this type of construction allows the actuation point for the linear actuator to be moved outwards from the center of the housing. Operation is thus made easier overall.

In einer ersten bevorzugten Ausführungsform ist vorgesehen, daß an der Rückseite des Leuchtengehäuses, d.h. an der dem Leuchtmittel entgegengesetzten Seite, die Betätigung des Hubantriebs angeordnet ist. Damit besteht der Vorteil, daß man mit dieser Art der Betätigung nun unmittelbar die Verstellung des Brennpunktes des Leuchtmittels zum Reflektor bei eingeschaltetem Leuchtmittel kontrollieren kann. Damit besteht nun keine Verletzungsgefahr mehr und das Leuchtmittel kann also im Betriebszustand verstellt werden, wodurch es z.B. nun möglich ist, die Leuchte auf ein bestimmtes, anzustrahlendes Objekt zu richten und eine optische Kontrolle zu haben, ob der Brennpunkt an einer bestimmten Fläche fokussiert wird oder nicht. Damit können optimale Ausleuchtungen von zu beleuchtenden Flächen eingestellt werden, was vorher nicht ohne weiteres möglich war.In a first preferred embodiment it is provided that on the back of the lamp housing, i.e. on the side opposite the illuminant, the actuation of the lifting drive is arranged. This has the advantage that with this type of actuation you can now directly control the adjustment of the focal point of the lamp to the reflector when the lamp is switched on. This means that there is no longer any risk of injury and the lamp can therefore be adjusted in the operating state, making it e.g. it is now possible to direct the luminaire towards a specific object to be illuminated and to have an optical control as to whether the focal point is focused on a specific surface or not. This enables optimal illumination of the surfaces to be illuminated, which was not easily possible before.

Nach einer Weiterbildung der vorliegenden Erfindung kann es vorgesehen sein, daß der Verstellantrieb für den Hubmechanismus von der Seite des Leuchtengehäuses her vorgesehen ist oder daß der Verstellantrieb - über entsprechende Werkzeuge - von vorne her erfolgt.According to a development of the present invention, it can be provided that the adjustment drive for the lifting mechanism is provided from the side of the lamp housing, or that the adjustment drive is carried out from the front, using appropriate tools.

Um den Hubantrieb mit einem größeren Verstellweg auszugestalten, ist es in einer weiteren Ausgestaltung der Erfindung vorgesehen, daß dem Verstellhebel zwei unterschiedliche Exzenterkurven zugeordnet sind, wobei sich eine untere Exzenterkurve an der Oberseite der Fassungsplatte abstützt, während sich eine obere Exzenterkurve an der Innenseite des Leuchtengehäuses abstützt.In order to design the linear actuator with a larger adjustment path, it is provided in a further embodiment of the invention that the adjustment lever is assigned two different eccentric curves, a lower eccentric curve being supported on the top of the mounting plate, while an upper eccentric curve is supported on the inside of the lamp housing supports.

Mit diesen beiden - gegeneinander gerichteten - Exzenterkurven wird nun eine Verdoppelung des Verstellweges erreicht, wobei während der Verdrehung des Verstellhebels um einen bestimmten Schwenkpunkt dieser Schwenkpunkt eine Verschiebung in der Verstellrichtung ausführt.With these two - oppositely directed - eccentric curves, the adjustment path is now doubled, whereby during the rotation of the adjustment lever about a certain pivot point, this pivot point carries out a displacement in the adjustment direction.

Es wird also allgemein festgestellt, daß sämtliche Lösungen für einen Hubantrieb für eine Fassungsplatte in Form von Verstellhebeln und /oder Kulissenführungen nach der vorliegenden Erfindung als erfinderisch beansprucht werden. Es gibt neben der händischen Verstellung der Fassungsplatte mit entsprechenden Verstellmitteln noch elektromotorische oder elektromagnetische Verstellmittel. Beispielsweise kann der vorher erwähnte Verstellhebel an dem freien , verschiebbaren Ende eines Ankers eines Elektromagneten angeordnet sein, so daß die Verstellung nun über die Ansteuerung des Elektromagneten erfolgt.It is thus generally stated that all solutions for a lifting drive for a mounting plate in the form of adjusting levers and / or link guides according to the present invention are claimed as inventive. In addition to the manual adjustment of the mounting plate with appropriate adjustment means, there are also electromotive or electromagnetic adjustment means. For example, the aforementioned adjustment lever can be arranged on the free, displaceable end of an armature of an electromagnet, so that the adjustment now takes place via the actuation of the electromagnet.

Damit kann mit einem Elektromagneten zwei verschiedene Brennpunktverstellungen durchgeführt werden, z.B. eine Minimum- und eine Maximum-Brennpunktposition.This means that two different focus adjustments can be carried out with one electromagnet, e.g. a minimum and a maximum focal position.

Ebenso ist es möglich, im Leuchtengehäuse einen elektromotorischen Verstellantrieb anzuordnen, der mit einem entsprechenden Verstellorgan, z.B. einer drehbar angetriebenen Exzenterscheibe zusammenwirkt, welches ebenfalls als Hubantrieb für die Fassungsplatte ausgebildet ist.It is also possible to arrange an electromotive adjustment drive in the luminaire housing, which is equipped with a corresponding adjustment element, e.g. a rotatably driven eccentric disc cooperates, which is also designed as a lifting drive for the mounting plate.

In vorteilhafter Ausgestaltung ist es weiterhin vorgesehen, daß die Fassungsplatte etwa den gleich großen Durchmesser wie das Gehäuse aufweist und als Hitzeschild ausgebildet ist. Die Fassungsplatte dient bei dieser Ausgestaltung für den dahinterliegenden Bereich mit den elektrischen Anschlüssen, Leitungen usw., insbesondere auch für die Handhabe, als Hitzeschild, so daß sich hinter der Fassungsplatte nur eine relativ geringe thermische Belastung ergibt.In an advantageous embodiment, it is further provided that the mounting plate has approximately the same diameter as the housing and is designed as a heat shield. In this embodiment, the mounting plate serves as a heat shield for the area with the electrical connections, lines, etc., in particular also for the handle, so that there is only a relatively low thermal load behind the mounting plate.

Weiterhin ist es vorteilhaft, daß an der Fassungsplatte Lappen oder Führungsstifte angesetzt sind, welche die Fassungsplatte gegenüber dem Gehäuse führen.Furthermore, it is advantageous that tabs or guide pins are attached to the mounting plate, which guide the mounting plate relative to the housing.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander. Alle in den Unterlagen - einschließlich der Zusammenfassung - offenbarten Angaben und Merkmale, insbesondere die in den Zeichnungen dargestellte räumliche Ausbildung werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another. All of the information and features disclosed in the documents - including the summary -, in particular the spatial design shown in the drawings, are claimed to be essential to the invention, insofar as they are new to the prior art, individually or in combination.

In einem Leuchtengehäuse 1 ist ein Reflektor 5 über zwei vordere Ringe 6,7 gehalten, wobei die Ringe 6,7 eine vordere Glasplatte 19 befestigen.In a lamp housing 1, a reflector 5 is held over two front rings 6, 7, the rings 6, 7 attaching a front glass plate 19.

Im Leuchtengehäuse 1 ist in den Verstellrichtungen (Pfeilrichtungen 27,28) eine Fassungsplatte 2 verstellbar angeordnet, wobei die Fassungsplatte 2 mit einer Fassung 3 verbunden ist. In der Fassung 3 ist das Leuchtmittel 4 befestigt. Im gezeigten Ausführungsbeispiel ist das Leuchtmittel 4 als Niedervolt-Halogenlampe ausgebildet; es können jedoch auch andere Leuchtmittel verwendet werden, wie z.B. Glühlampen, Gasentladungslampen, Kompaktleuchtstofflampen und dergleichen mehr.In the luminaire housing 1, a socket plate 2 is adjustably arranged in the adjustment directions (arrow directions 27, 28), the socket plate 2 being connected to a socket 3. The bulb 4 is fastened in the socket 3. In the exemplary embodiment shown, the illuminant 4 is designed as a low-voltage halogen lamp; however, other illuminants can also be used, e.g. Incandescent lamps, gas discharge lamps, compact fluorescent lamps and the like.

Das Leuchtengehäuse 1 ist mit einer Halterung 8 in nicht näher dargestellter Weise mit z.B. einem Rohr verbunden oder dergleichen mehr.The lamp housing 1 is with a bracket 8 in a manner not shown with e.g. connected to a pipe or the like.

Im Innenraum des Leuchtengehäuses 1 ist ein Verstellhebel 9 (vergl. auch Figur 5) verstellbar und drehbar angeordnet. Hierbei wird eine Schwenkachse 11 gebildet, die dadurch erreicht wird, daß der Verstellhebel 9 einen aus seiner Ebene herausgebogenen Kopf 13 aufweist, der durch einen etwa C-profilierte Ausnehmung 38 aus dem Material des Verstellhebels 9 herausgebogen ist. Gemäss den Figuren 1 und 4 greift dieser abgekröpfte Kopf 13 in einen Schlitz 12 im Leuchtengehäuse ein und bildet demgemäß die Schwenkachse 11.In the interior of the lamp housing 1, an adjusting lever 9 (see also FIG. 5) is adjustable and rotatable. Here, a pivot axis 11 is formed, which is achieved in that the adjusting lever 9 has a head 13 bent out of its plane, which is bent out of the material of the adjusting lever 9 by an approximately C-profiled recess 38. According to FIGS. 1 and 4, this bent head 13 engages in a slot 12 in the lamp housing and accordingly forms the pivot axis 11.

Der Schlitz 12 hat hierbei einen C-förmigen Querschnitt, um zu vermeiden, daß der Kopf 13 nach vorne herausfällt.The slot 12 here has a C-shaped cross section to prevent the head 13 from falling out towards the front.

Wichtig ist, daß zur Erreichung eines verdoppelten Verstellweges der Verstellhebel 9 eine untere Exzenterkurve 36 aufweist, mit der er sich an der federbelasteten Fassungsplatte 2 abstützt. Demgegenüberliegend weist der Verstellhebel 9 eine obere Exzenterkurve 37 auf, mit der er sich an der Unterseite der oberen Stirnfläche des Leuchtengehäuses 1 abstützt.It is important that, in order to achieve a doubled adjustment path, the adjustment lever 9 has a lower eccentric curve 36 with which it adjusts itself supported on the spring-loaded socket plate 2. In contrast, the adjusting lever 9 has an upper eccentric curve 37, with which it is supported on the underside of the upper end face of the lamp housing 1.

Die Federbelastung der Fassungsplatte 2 wird dadurch erreicht, daß in der Fassungsplatte 2 eine Bohrung vorhanden ist, durch welche eine Schaftschraube 14 hindurchgreift. Im Zwischenraum zwischen dem Kopf 16 der Schaftschraube 14 und der Unterseite der Fassungsplatte 2 ist hierbei eine Feder 15 angeordnet.The spring loading of the mounting plate 2 is achieved in that there is a hole in the mounting plate 2 through which a socket screw 14 extends. A spring 15 is arranged in the space between the head 16 of the socket head screw 14 and the underside of the mounting plate 2.

Das bolzenseitige Ende der Schaftschraube 14 ist hierbei in eine zugeordnete Bohrung 17 im Leuchtengehäuse 1 eingeschraubt.The bolt-side end of the shaft screw 14 is screwed into an associated bore 17 in the lamp housing 1.

Zur Geradführung der Fassungsplatte 2 sind aus der Ebene der Fassungsplatte herausgebogene Führungslappen 18 vorgesehen, die bevorzugt an einander gegenüberliegenden Enden der Fassungsplatte 2 angeordnet sind, die in entsprechenden Schlitzen geführt sind, die parallel zu dem Schlitz 12 verlaufen.For straight guidance of the mounting plate 2, guide tabs 18 are provided which are bent out of the plane of the mounting plate and are preferably arranged on opposite ends of the mounting plate 2, which are guided in corresponding slots which run parallel to the slot 12.

Der Verstellhebel 9 weist einen oberen Ansatz 43 auf, der mit einer bevorzugt aus Kunststoff ausgebildeten Handhabe 10 verbunden ist.The adjusting lever 9 has an upper extension 43 which is connected to a handle 10 which is preferably made of plastic.

Wird nun der Verstellhebel 9 über die Handhabe 10 im Bereich eines Schlitzes 21 im Leuchtengehäuse 1 verschwenkt, dann schwenkt er um seine Schwenkachse 11, wobei sich die Schwenkachse 11 gleichzeitig im Bereich der vertikal ausgerichteten Nut 12 verschiebt. Hierbei stützt sich die obere Exzenterkurve 37 an der Innenseite des Leuchtengehäuses ab, während sich die untere Exzenterkurve 36 an der Oberseite der federbelasteten Fassungsplatte 2 abstützt. Nachdem gemäss Figur 5 die beiden Exzenterkurven 36,37 entgegensetzte Steigung aufweisen (entgegengesetzt gerichtet sind) ergibt sich somit ein doppelter Verstellweg der Fassungsplatte 2 in den Pfeilrichtungen 27,28 im Vergleich dazu, als wenn nur eine einzige Exzenterkurve 36 oder 37 vorhanden wäre.If the adjusting lever 9 is now pivoted via the handle 10 in the region of a slot 21 in the lamp housing 1, then it pivots about its pivot axis 11, the pivot axis 11 simultaneously shifting in the region of the vertically aligned groove 12. Here, the upper eccentric curve 37 is supported on the inside of the lamp housing, while the lower eccentric curve 36 is supported on the upper side of the spring-loaded mounting plate 2. Since, according to FIG. 5, the two eccentric curves 36, 37 have opposite inclinations (are directed in opposite directions), this results in a double one Adjustment path of the mounting plate 2 in the arrow directions 27, 28 in comparison to if only a single eccentric curve 36 or 37 were present.

In Figur 3 ist die Fassungsplatte 2 in zwei verschiedenen Stellungen 2,2' dargestellt, wobei das Leuchtmittel 4 entfernt ist und stattdessen die Ausnehmung 20 für die Befestigung der Fassung 3 erkennbar ist.In FIG. 3, the holder plate 2 is shown in two different positions 2, 2 ', the illuminant 4 being removed and instead the recess 20 for attaching the holder 3 being recognizable.

In Figur 5 sind die beiden einander gegenüberliegenden und entgegengesetzt gerichteten Exzenterkurven 36,37 am Verstellhebel 9 dargestellt.FIG. 5 shows the two opposing and oppositely directed eccentric curves 36, 37 on the adjusting lever 9.

Hierbei ist erkennbar, daß die obere Exzenterkurve 37 einen Radius 39 mit einem von der Längsmittelachse seitlich versetzten Mittelpunkt 40 aufweist, während die gegenüberliegende Exzenterkurve 36 einen entgegengesetzt vom erstgenannten Mittelpunkt 40 angeordneten Mittelpunkt 41 aufweist, welchem der Radius 42 zugeordnet ist.It can be seen here that the upper eccentric curve 37 has a radius 39 with a center 40 laterally offset from the longitudinal center axis, while the opposite eccentric curve 36 has a center 41 opposite to the former center 40, to which the radius 42 is assigned.

In Figur 6 ist als Verstellantrieb eine Kulissenführung dargestellt, wo ein Kulissenhebel 29 im Bereich einer Schwenkachse 30 am Leuchtengehäuse 1 schwenkbar gelagert ist. Die Fassungsplatte 2 ist hierbei mit einem Stift 32 verbunden, der in die Führung 31 eingreift. Durch die Verschwenkung des Kulissenhebels 29 kann somit ebenfalls eine Verstellung in den Pfeilrichtungen 27,28 der Fassungsplatte 2 erfolgen.FIG. 6 shows a link guide as the adjustment drive, where a link lever 29 is pivotably mounted on the lamp housing 1 in the region of a pivot axis 30. The mounting plate 2 is connected to a pin 32 which engages in the guide 31. By pivoting the link lever 29, an adjustment in the arrow directions 27, 28 of the mounting plate 2 can thus also take place.

Figur 7 zeigt als weiteren Verstellantrieb eine Exzenterscheibe 44, die drehfest mit einer Achse 45 verbunden ist, die in der Seitenwand des Gehäuses 1 drehbar gelagert ist. Durch die Verdrehung der Achse 45 drückt sich somit die Exzenterscheibe 44 an der Oberseite der federbelasteten Fassungsplatte 2 ab, die demzufolge ebenfalls in den Pfeilrichtungen 27,28 höhenverstellt wird.FIG. 7 shows, as a further adjustment drive, an eccentric disk 44 which is connected in a rotationally fixed manner to an axis 45 which is rotatably mounted in the side wall of the housing 1. Due to the rotation of the axis 45, the eccentric disc 44 is thus pressed against the top of the spring-loaded mounting plate 2, which is consequently also adjusted in height in the direction of the arrows 27, 28.

Aus den Figuren 1 bis 4 ist ersichtlich, daß die Fassungsplatte 2 etwa den gleich großen Durchmesser wie das Gehäuse 1 aufweist, wobei die Fassungsplatte 2 gleichzeitig als Hitzeschild dient. Der Bereich hinter der Fassungsplatte mit den elektrischen Anschlüßen, Leitungen usw. sowie auch die Handhabung bzw. der Verstellhebel 9 sind insoweit nicht so hoch belastet als dies ohne Fassungsplatte 2 wäre, insbesondere bei kreisförmiger Ausgestaltung der Fassungsplatte 2.It can be seen from FIGS. 1 to 4 that the mounting plate 2 has approximately the same diameter as the housing 1, the mounting plate 2 also serving as a heat shield. The area behind the mounting plate with the electrical connections, lines, etc., and also the handling or the adjusting lever 9 are not so heavily loaded as would be without a mounting plate 2, in particular with a circular design of the mounting plate 2.

Aus der Figur 2 und den Figuren 7 ist ersichtlich, daß die Lappen 18 bzw. die Führungsstifte 22 die besondere Aufgabe erfüllen, daß die Fassungsplatte 2 gegenüber dem Gehäuse geführt wird. Die Lappen 18 bzw. die Führungsstifte 22 sind hierbei parallel zur Längsachse des Gehäuses an der Fassungsplatte angesetzt und laufen in entsprechenden Führungsschlitzen des Gehäuses, so daß sich bei der Verstellung der Fassungsplatte 2 eine vorteilhafte Führung derselben ergibt. Es ist aber auch möglich, die Fassungsplatte 2 mit in radialer Richtung weisende Führungselemente, etwa in Schlitzbereichen des Gehäuses oder in Nutenführungen des Gehäuses, zu führen.From Figure 2 and Figures 7 it can be seen that the tabs 18 and the guide pins 22 perform the special task that the mounting plate 2 is guided relative to the housing. The tabs 18 and the guide pins 22 are in this case placed parallel to the longitudinal axis of the housing on the mounting plate and run in corresponding guide slots in the housing, so that when the mounting plate 2 is adjusted, it is advantageously guided. However, it is also possible to guide the mounting plate 2 with guide elements pointing in the radial direction, for example in slot areas of the housing or in groove guides of the housing.

Claims (7)

  1. Focal point adjustment of a lighting means in a housing, wherein the lighting means is arranged on a mounting plate and is displaced in the direction of its longitudinal axis, for the purpose of focussing, by means of a lifting drive which assigns an adjustment movement to the mounting plate (2) in the direction of radiation of the reflector (5) , characterised in that the lifting drive for the mounting plate (2) is constructed as an adjusting lever (9) and/or slot hole (31), which rests at least with an eccentric curve (36) against the mounting plate (2).
  2. Focal point adjustment according to Claim 1, characterised in that the actuation of the lifting drive is arranged on the reverse side of the housing (1) on the side opposed to the lighting means (4).
  3. A focal point adjustment according to Claim 1, characterised in that the adjusting drive for the lifting mechanism takes place from the side of the housing, or that the adjusting drive takes place from the front via corresponding tools.
  4. A focal point adjustment according to Claim 1, characterised in that the adjusting lever (9) has a further eccentric curve (37) which rests against the inner side of the housing (1).
  5. A focal point adjustment according to Claim 1, characterised in that the mounting plate (2) is displaceably guided on one or more guide pins (22) in the housing (1) and that the mounting plate (2) rests in a spring-loaded manner against the lifting device.
  6. A focal point adjustment according to Claims 1 to 5, characterised in that the mounting plate (2) is constructed as a heat plate in order to protect the devices and lines present on the rear side and therefore has approximately the same diameter as the housing (1).
  7. A focal point adjustment according to Claim 1, characterised in that lugs (18) or guide pins (22) are attached to the mounting plate (2), which guide the mounting plate (2) with respect to the housing (1).
