- the lamp shown in the aforementioned brochure publication has a U-shaped mounting bracket with two bracket legs, at the free ends of which a guide block for each support rod is arranged coaxially with a tilt axis. Each guide block overlaps the support rod assigned to it, leaving an extensive recess. Both support rods are arranged parallel to each other in the plane of the tilt axis and can be tilted together with the two guide blocks. According to the prospectus publication, a main housing part and additional radiator parts are arranged axially displaceably and lockable on the supporting rods between the two supporting rods.
- the invention has for its object to provide a spotlight that is particularly suitable to accommodate relatively heavy spotlight additional parts without overloading the load-bearing lamp construction parts.
- this object is achieved in that, in addition to the inclination adjustment in the axial direction, the support rods are accommodated relatively displaceably by the guide blocks, that the main housing part is fixed rigidly and immovably between the two support rods by means of the two housing attachment points, and that each recess on the guide block side is separated from the associated housing Fastening point is traversable in the axial direction of the support rod.
- the peculiarity of the spotlight luminaire according to the invention is first of all that the main housing part, together with the two support rods, forms a completely rigid, torsionally rigid assembly which does not warp even under extreme asymmetrical weight loads. It is essential, however, that this rigid assembly, in addition to the tilt adjustment, is also axially displaceable on the inside of the bracket legs along the support rods in the tilt axis, ie by means of the tilt adjustment device.
- the arrangement according to the invention therefore represents, as it were, an axially displaceable balance beam.
- the rigid assembly formed from the main housing part and supporting rods - together with all radiator elements - Additional parts - be moved and locked in their axial position relative to the stirrup legs so that the center of gravity of the arrangement is either in or immediately adjacent to the tilt axis.
- a tilt-lock-lockable guide block is arranged coaxially with the tilt axis on the inside at each free end of a bracket leg, which only overlaps the support rods over a circumferential angle of greater than 180 ° with a guide channel, but here one of the housing attachment points between the main housing and the support rods in the axial direction traversable recess. That design according to the invention allows even greater flexibility with regard to the possibility of an axial relative adjustment of the rigid assembly, which is mainly composed of support rods and main housing part.
- each housing fastening point forms a tab which is rigidly and positively fastened both to the main housing and to the support rods. Such tabs also distance the main housing part from the support rods.
- an additional weight compensation axial adjustment of additional radiator parts can be done according to the invention by designing the support rods in that the support rods are designed rack-like at least on parts of their axial length and at least over a circumferential angle range for the engagement of an accessory-side pinion.
- the spotlight 10 has a U-shaped bracket 11 with two bracket legs 12, 13 and a bracket web 14 integrally connecting the latter, which is provided on the top with a releasable fastening unit 15.
- the fastening unit 15 is used for mounting, for example, on a part of a building or on a support part specially designed for spotlights.
- the fastening unit 15 can also - in the case of a lighter overall design of the spotlight - be designed as an infeed adapter which engages in a contacting manner in a power take-off rail, not shown.
- An essential component of the spotlight 10 is a main housing part 16 which is rigidly and immovably fastened to two support rods 18 which are parallel to one another by means of two tabs 17 which are arranged diametrically opposite one another and represent housing fastening points.
- the main housing part 16 is fixedly and immovably connected to the two support rods 18 via the tabs 17 in such a way that an approximately H-shaped rigid and connection-rigid assembly is formed in its basic shape, which is denoted by A, B and C in FIG. 1 dash-dotted lines is symbolized.
- Each guide block 19, 20 forms a guide channel 21, which the support rods 18 o overlaps in the present case with a circumferential angle of about 270th This results in each guide block 19, 20 in each case an inwardly open to the main housing part 16 recess 22, which of the tabs 17, which represent the above-described rigid connection between the main housing part 16 and the two support rods 18, along the x in Fig. 1 can be traversed in both axial adjustment directions.

- the ends of the slots 41 serve the centering pins 40 as inclination limit stops. Since the clamping disks 36 have a plurality of hiding holes 43, the tilting region of the spotlight can be oriented, for example from horizontal to vertical.
- the electrical supply of the spotlight 10 is done via separate cable feeds, not shown. Stud bolts 39 serve to releasably lock the guide blocks 19, 20 on the support rods 18.
Description
Die Erfindung betrifft eine Strahlerleuchte entsprechend dem Oberbegriff des Anspruchs 1. Eine solche Strahlerleuchte ist durch das ERCO-Leuchtenprogramm (Prospekt Nr. 2869010), Ausgabe 1991/92, erste Umschlagseite außen, Seite 288, letzte Umschlagseite innen, letzte Umschlagseite außen, bekanntgeworden.The invention relates to a spotlight according to the preamble of claim 1. Such a spotlight has become known through the ERCO lighting program (brochure no. 2869010), 1991/92 edition, first cover page outside, page 288, last cover page inside, last cover page outside.
Die in vorgenannter Prospektveröffentlichung gezeigte Leuchte weist einen U-förmigen Haltebügel mit zwei Bügelschenkeln auf, an deren freien Enden innen koaxial mit einer Neigeachse je ein Führungsblock für je eine Tragstange angeordnet ist. Jeder Führungsblock übergreift die ihm zugeordnete Tragstange unter Freilassung einer umfänglichen Aussparung. Beide Tragstangen sind im Parallelabstand zueinander in der Ebene der Neigeachse angeordnet und gemeinsam mit den beiden Führungsblöcken neigeverstellbar. Entsprechend der Prospektveröffentlichung sind zwischen den beiden Tragstangen ein Hauptgehäuseteil sowie Strahler-Zusatzteile axialverschieblich und verstellarretierbar auf den Tragstangen angeordnet.The lamp shown in the aforementioned brochure publication has a U-shaped mounting bracket with two bracket legs, at the free ends of which a guide block for each support rod is arranged coaxially with a tilt axis. Each guide block overlaps the support rod assigned to it, leaving an extensive recess. Both support rods are arranged parallel to each other in the plane of the tilt axis and can be tilted together with the two guide blocks. According to the prospectus publication, a main housing part and additional radiator parts are arranged axially displaceably and lockable on the supporting rods between the two supporting rods.
Ausgehend von der eingangs erwähnten Prospektveröffentlichung, liegt der Erfindung die Aufgabe zugrunde, eine Strahlerleuchte zu schaffen, die besonders geeignet ist, relativ schwere Strahler-Zusatzteile ohne Überlastung der tragenden Leuchten-Konstruktionsteile aufzunehmen.Based on the prospectus publication mentioned at the beginning, the invention has for its object to provide a spotlight that is particularly suitable to accommodate relatively heavy spotlight additional parts without overloading the load-bearing lamp construction parts.
Entsprechend der Erfindung wird diese Aufgabe dadurch gelöst, daß die Tragstangen zusätzlich zur Neigeverstellung in Axialrichtung relativverschieblich von den Führungsblöcken aufgenommen sind, daß das Hauptgehäuseteil mittels der beiden Gehäusebefestigungsstellen starr und unverschieblich zwischen den beiden Tragstangen befestigt ist und daß jede führungsblockseitige Aussparung von der zugehörigen Gehäuse-Befestigungsstelle in Axialrichtung der Tragstange durchfahrbar ist.According to the invention, this object is achieved in that, in addition to the inclination adjustment in the axial direction, the support rods are accommodated relatively displaceably by the guide blocks, that the main housing part is fixed rigidly and immovably between the two support rods by means of the two housing attachment points, and that each recess on the guide block side is separated from the associated housing Fastening point is traversable in the axial direction of the support rod.
Die Eigenart der erfindungsgemäßen Strahlerleuchte besteht zunächst darin, daß das Hauptgehäuseteil gemeinsam mit den beiden Tragstangen eine völlig starre, verwindungssteife Baugruppe bildet, die sich auch bei extremer asymmetrischer Gewichtsbelastung nicht verzieht. Wesentlich ist aber nun, daß diese starre Baugruppe zusätzlich zur Neigeverstellung auch entlang den Tragstangen axialverschieblich in der Neigeachse, d.h. mittels der Neigeverstelleinrichtung, innenseitig an den Bügelschenkeln gehalten ist.The peculiarity of the spotlight luminaire according to the invention is first of all that the main housing part, together with the two support rods, forms a completely rigid, torsionally rigid assembly which does not warp even under extreme asymmetrical weight loads. It is essential, however, that this rigid assembly, in addition to the tilt adjustment, is also axially displaceable on the inside of the bracket legs along the support rods in the tilt axis, ie by means of the tilt adjustment device.
Die erfindungsgemäße Anordnung stellt daher gewissermaßen einen in seiner Neigelagerung axialverschieblichen Waagebalken dar. Auf diese Weise kann in Abhängigkeit von dem Gewicht der axial vor bzw. axial hinter dem Hauptgehäuseteil angeordneten Strahler-Zusatzteile die aus Hauptgehäuseteil und Tragstangen gebildete starre Baugruppe - gemeinsam mit allen Strahler-Zusatzteilen - in ihrer axialen Relativlage zu den Bügelschenkeln so verschoben und arretiert werden, daß sich der Schwerpunkt der Anordnung entweder in oder unmittelbar benachbart der Neigeachse befindet.The arrangement according to the invention therefore represents, as it were, an axially displaceable balance beam. In this way, depending on the weight of the additional radiator parts arranged axially in front of or axially behind the main housing part, the rigid assembly formed from the main housing part and supporting rods - together with all radiator elements - Additional parts - be moved and locked in their axial position relative to the stirrup legs so that the center of gravity of the arrangement is either in or immediately adjacent to the tilt axis.
Es ist klar, daß die erfindungsgemäße Strahlerleuchte bei richtiger Einstellung insbesondere die bügelstegseitige Befestigungsstelle von schädlichen Querkräften völlig freihält.It is clear that the spotlight according to the invention, when set correctly, in particular keeps the attachment point on the side of the strap bridge completely free of harmful transverse forces.
Entsprechend der Erfindung ist koaxial mit der Neigeachse innen an jedem freien Ende eines Bügelschenkels ein neigeverstellarretierbarer Führungsblock angeordnet, welcher die Tragstangen zwar nur auf einem Umfangswinkel von größer als 180° mit einem Führungskanal übergreift, hierbei jedoch eine von den Gehäuse-Befestigungsstellen zwischen dem Hauptgehäuse und den Tragstangen in deren Axialrichtung durchfahrbare Aussparung bildet. Jene erfindungsgemäße Ausbildung gestattet eine noch größere Flexibilität hinsichtlich der Möglichkeit einer axialen Relativverstellung der hauptsächlich aus Tragstangen und Hauptgehäuseteil gebildeten starren Baugruppe.According to the invention, a tilt-lock-lockable guide block is arranged coaxially with the tilt axis on the inside at each free end of a bracket leg, which only overlaps the support rods over a circumferential angle of greater than 180 ° with a guide channel, but here one of the housing attachment points between the main housing and the support rods in the axial direction traversable recess. That design according to the invention allows even greater flexibility with regard to the possibility of an axial relative adjustment of the rigid assembly, which is mainly composed of support rods and main housing part.
In weiterer Ausgestaltung der Erfindung bildet jede Gehäuse-Befestigungsstelle eine sowohl am Hauptgehäuse als auch auf den Tragstangen starr und formschlüssig befestigte Lasche. Derartige Laschen distanzieren zugleich das Hauptgehäuseteil von den Tragstangen.In a further embodiment of the invention, each housing fastening point forms a tab which is rigidly and positively fastened both to the main housing and to the support rods. Such tabs also distance the main housing part from the support rods.
Eine besonders leicht und präzis zu handhabende, einem zusätzlichen Gewichtsausgleich dienende Axialverstellung von Strahler-Zusatzteilen kann durch Ausgestaltung der Tragstangen erfindungsgemäß dadurch geschehen, daß die Tragstangen mindestens auf Teilen ihrer Axiallänge und mindestens auf einem Umfangswinkelbereich für den Eingriff eines zusatzteilseitigen Zahntriebs zahnstangenartig ausgebildet sind.A particularly easy and precise to use, an additional weight compensation axial adjustment of additional radiator parts can be done according to the invention by designing the support rods in that the support rods are designed rack-like at least on parts of their axial length and at least over a circumferential angle range for the engagement of an accessory-side pinion.

In den Zeichnungen ist eine Strahlerleuchte insgesamt mit der Bezugsziffer 10 bezeichnet.In the drawings, a spotlight is generally designated by the
Die Strahlerleuchte 10 weist einen U-förmigen Haltebügel 11 mit zwei Bügelschenkeln 12, 13 und einem letztere miteinander einstückig verbindenden Bügelsteg 14 auf, welcher oberseitig mit einer lösbaren Befestigungseinheit 15 versehen ist. Die Befestigungseinheit 15 dient der Halterung beispielsweise an einem Gebäudeteil oder an einem eigens für Strahlerleuchten ausgelegten Tragteil. Die Befestigungseinheit 15 kann ebenfalls - bei leichterer Gesamtausführung der Strahlerleuchte - als Einspeisungsadapter ausgebildet sein, welcher kontaktgebend in eine nicht dargestellte Stromentnahmeschiene eingreift.The
Wesentlicher Bestandteil der Strahlerleuchte 10 ist ein Hauptgehäuseteil 16, welches mittels zweier diametral außen gegenüberliegend angeordneter, Gehäusebefestigungsstellen darstellender Laschen 17 starr und unverschieblich an zwei im Parallelabstand zueinander befindlichen Tragstangen 18 befestigt ist.An essential component of the
Das Hauptgehäuseteil 16 ist über die Laschen 17 derart mit den beiden Tragstangen 18 fest und unverschieblich verbunden, daß eine in ihrer Grundform etwa H-förmige starre und verbindungssteife Baugruppe gebildet ist, welche in Fig. 1 durch die mit A, B und C bezeichneten strichpunktierten Linien versinnbildlicht ist.The
Innen an beiden freien Enden der Bügelschenkel 12, 13 sind Führungsblöcke 19, 20 um eine Neigeachse Z neigeverstellarretierbar angeordnet.On the inside at both free ends of the
Jeder Führungsblock 19, 20 bildet einen Führungskanal 21, welcher die Tragstangen 18 im vorliegenden Falle nur mit einem Umfangswinkel von etwa 270o übergreift. Hierdurch entsteht bei jedem Führungsblock 19, 20 jeweils eine zum Hauptgehäuseteil 16 nach innen offene Aussparung 22, welche von den Laschen 17, welche die vorbeschriebene starre Verbindung zwischen dem Hauptgehäuseteil 16 und den beiden Tragstangen 18 darstellen, entlang den in Fig. 1 mit x bezeichneten beiden Axial-Verstellrichtungen durchfahren werden kann.Each
Anhand von Fig. 1 ist nunmehr vorstellbar, daß die gesamte etwa H-förmige Baugruppe, gekennzeichnet durch die strichpunktierten Linien A, B und C, welche hauptsächlich aus den beiden Tragstangen 18, den Laschenteilen 17 und dem Hauptgehäuseteil 16 besteht, in beiden Richtungen entlang dem mit x bezeichneten Doppelpfeil hin- und hergeschoben werden kann. Auf diese Weise ist es möglich, einen etwa waagebalkenartigen Gewichtausgleich zu schaffen. Dieses auch für den Fall, daß bei einer einmal vorgenommenen, z.B. optisch relevanten, Einstellung der Gesamtanordnung einer Strahlerleuchte weitere Strahler-Zusatzteile auf den Tragstangen 18 angeordnet werden müssen. Andererseits kann aus optischen Gründen eine Axialverschiebung eines Zusatzbauteils auf den Tragstangen 18 geboten sein. Jede mit solchen Maßnahmen einhergehende Änderung der Gewichtsverteilung kann sodann durch die erwähnte Axialverstellung in Richtung des Doppelpfeils x relativ zu den Bügelschenkeln 12, 13 ausbalanciert werden.1 is now conceivable that the entire approximately H-shaped assembly, characterized by the dash-dotted lines A, B and C, which mainly consists of the two
Gemäß Fig. 1 ist beispielsweise links vor dem Hauptgehäuseteil 16 eine Farbfilter-Einheit 34 mittels zweier überlanger Verstellhülsen 23, 24 angeordnet. Eine derartige auf der zugehörigen Tragstange axial verschiebbare Verstellhülse 23 kann mit einem kulissenartigen Schlitz 25 versehen sein, der von einer die Tragstange 18 in einem Gewindeloch 26 durchsetzenden Klemmschraube 27 durchgriffen ist.1, for example, a
Die andere Verstellhülse 24 kann einen mittels eines Handrades 28 betätigbaren Zahntrieb beinhalten, dessen in der Verstellhülse 24 drehgelagertes Zahnrad 29 in eine zahnstangenartige Ausbildung 30 außen an der Tragstange 18 eingreift.The other adjusting
Gemäß Fig. 1 rechts hinter dem Hauptgehäuseteil 16, welches z.B. eine optische Linse aufnehmen kann, sind ein Lampengehäuse 31 und rechts von diesem ein Vorschaltgerät 32 mittels eigener Verstellhülsen 33 entlang dem Doppelpfeil x axialverschieblich auf den Tragstangen 18 angeordnet.1 right behind the
Wenn man bei der in Fig. 1 schematisch dargestellten Anordnung einen Gewichtsausgleich vornehmen wollte, so wäre vorstellbar, daß die aus dem Hauptgehäuseteil 16 mit Laschen 17 und Tragstangen 18 bestehende Hauptbaugruppe gemeinsam mit den Strahler-Zusatzteilen 34, 31, 32 um einen bestimmten Betrag nach links verschoben werden müßte. Anstelle von Verstellhülsen 33 könnten beispielsweise beiderseits außen an den Strahler-Zusatzteilen 31, 32 auch relativ schmale Führungsfortsätze ausgebildet sein, welche in seitliche Führungsnuten der Tragstangen 18 eingreifen könnten. Auf diese Weise könnten bei einer Axialverschiebung der von den Tragstangen 18 gehaltenen Gesamtanordnung auch derartige Fortsätze die Aussparungen 22 der Führungsblöcke 19, 20 durchfahren.If one wanted to carry out a weight compensation in the arrangement shown schematically in FIG. 1, it would be conceivable that the main assembly consisting of the
Zur Neigeverstellarretierung sind den Führungsblöcken 19, 20 jeweils einen Bügelschenkel 12 oder 13 zwischen sich einklemmende Klemmscheiben 35, 36 zugeordnet, deren Klemmkraft über Zentralschrauben 37 eingestellt werden kann. Mit der rechts in Fig. 3 dargestellten Zentralschraube 37 kann die Klemmkraft zur Erzielung einer bestimmten Hemmung bleibend eingestellt werden, während die links in Fig. 3 dargestellte Zentralschraube 37 mittels eines Handhebels (38) derart fest angezogen werden kann, daß die Neigeverstelleinrichtung blockiert ist.For tilt adjustment locking, the guide blocks 19, 20 are each assigned a
Für beide Klemmscheibenanordnungen 35, 36 gilt folgendes: Die Klemmscheibe 36 greift mit einer Zentriernabe 42 in ein kreisrundes Achsloch des Schenkels 12 oder 13 ein. Ein Zentrierstift 40 durchsetzt die Klemmscheibe 36 lose in einem Versteckloch 43, den Schenkel 12, 13 lose in einer teilkreisförmigen Schlitzkulisse 41 und ist in ein Gewindeloch der Klemmscheibe 35 eingeschraubt. Die Enden der Schlitzkulissen 41 dienen den Zentrierstifen 40 als Neigebegrenzungs-Anschläge. Da die Klemmscheiben 36 mehrere Verstecklöcher 43 aufweisen, kann der Neigebereich der Strahlerleuchte wahlweise orientiert werden, z.B. von horizontal auf vertikal.The following applies to both
Die elektrische Einspeisung der Strahlerleuchte 10 geschieht über nicht dargestellte gesonderte Kabelzuführungen. Zur lösbaren Arretierung der Führungsblöcke 19, 20 auf den Tragstangen 18 dienen Stiftschrauben 39.The electrical supply of the
