Description

Die Erfindung betrifft einen Strahler mit gestufter Reflektorfläche für linienförmige Lichtquellen.The invention relates to a radiator with a stepped reflector surface for linear light sources.

Strahler dieser Art werden im Regelfall zur Erzielung einer flächigen Beleuchtung und auch als Wandfluter eingesetzt. Bekannte Strahler dieser Art sind häufig relativ voluminös ausgebildet und erheblichen Wärmebelastungen ausgesetzt.Spotlights of this type are generally used to achieve extensive lighting and also as wallwashers. Known radiators of this type are often of relatively voluminous design and are exposed to considerable heat loads.

Aufgabe der Erfindung ist es, einen Strahler der eingangs genannten Art besonders kompakt und leicht auszubilden und dabei dennoch die gegebenenfalls erforderlichen hohen Lichtleistungen zu gewährleisten, ohne daß dabei Wärmeabführungsprobleme bestehen.The object of the invention is to make a radiator of the type mentioned particularly compact and light and still ensure the high light outputs that may be required, without there being heat dissipation problems.

Gelöst wird diese Aufgabe nach der Erfindung im wesentlichen dadurch, daß die Stufung sowie die Neigung der zur Lichtquelle gerichteten reflektierenden Teilflächen der in ihrer Längserstreckung parallel zur Lichtquelle verlaufenden Reflektorfläche beiderseits der Reflektormittelebene unterschiedlich sind, und daß die Reflektorfläche zwischen vorzugsweise als Fassungsträger dienenden Seitenscheiben angeordnet ist, die mittels einer rückseitig der Reflektorfläche gelegenen Trägerstruktur gehalten sind.This object is achieved according to the invention essentially in that the gradation and the inclination of the reflecting partial surfaces directed towards the light source of the reflector surface running parallel to the light source in their longitudinal extent are different on both sides of the central reflector plane, and in that the reflector surface is arranged between side windows which preferably serve as a mount carrier which are held by means of a support structure located on the back of the reflector surface.

Diese Ausgestaltung ermöglicht einen symmetrischen Strahleraufbau in besonders flacher Ausführung bei gleichzeitig gewährleisteter asymmetrischer Abstrahlung.This configuration enables a symmetrical radiator structure in a particularly flat design while at the same time ensuring asymmetrical radiation.

Gemäß einer bevorzugten Ausführungsform besteht der Reflektor aus einem ablängbaren Stranggußprofil, das gleichzeitig das Strahlergehäuse bildet und mit der Trägerstruktur insbesondere mittensymmetrisch verbindbar ist.According to a preferred embodiment, the reflector consists of an extruded profile that can be cut to length, which at the same time forms the radiator housing and can be connected to the support structure in particular in a center-symmetrical manner.

Nach einer weiteren besonders vorteilhaften Ausgestaltung der Erfindung besteht der Reflektor aus lichtreflektierende Teilflächen bildenden Einzelelementen, die an den Seitenscheiben gehaltert sind, wobei rückseitig der lichtreflektierenden Teilflächen ein weiterer, flächig ausgebildeter und vorzugsweise aus Lochblech bestehender Reflektor angeordnet ist. Auf diese Weise läßt sich eine Kombination von gerichtetem Licht mit indirektem Licht erzielen, obwohl der Strahler in seinem Erscheinungsbild als geschlossener Reflektor wirkt. Mit einem derartigen Strahler kann ein besonders gutes Raumlicht erzeugt werden, wobei im Strahler aufgrund der gegebenen besonders guten Durchlüftung keinerlei Wärmeprobleme entstehen.According to a further particularly advantageous embodiment of the invention, the reflector consists of light reflecting Individual elements forming partial surfaces, which are held on the side windows, with a further flat-shaped reflector, preferably made of perforated sheet metal, arranged on the back of the light-reflecting partial surfaces. In this way, a combination of directed light with indirect light can be achieved, although the emitter acts in its appearance as a closed reflector. A particularly good ambient light can be generated with such a radiator, with no heat problems arising in the radiator due to the particularly good ventilation.

Besonders vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Particularly advantageous embodiments of the invention are specified in the subclaims.

Figur 1 zeigt in schematischer Weise den prinzipiellen Aufbau eines Strahlers mit asymmetrischer Abstrahlung, dessen Reflektor die Rückwand des Strahlergehäuses bildet und aus einem innenseitig eloxierten Aluminiumprofil besteht, das beiderseits der Mittelebene 6 unterschiedlich gestuft ist.Figure 1 shows schematically the basic structure of a radiator with asymmetrical radiation, the reflector of which forms and forms the rear wall of the radiator housing there is an anodized aluminum profile on the inside, which is differently graded on both sides of the central plane 6.

Die mit einer langgestreckten Lichtquelle 3 zusammenwirkende Reflektorfläche 2 besteht aus reflektierenden Teilflächen 4 und zwischen diesen angeordneten, aufgrund ihrer Orientierung zumindest im wesentlichen lichttoten Teilflächen 5. Die Neigung der jeweiligen Teilflächen ist unterschiedlich und so gewählt, daß sich die angestrebte asymmetrische Abstrahlcharakteristik ergibt. Dabei sind die Winkel zwischen den reflektierenden Teilflächen 4 und den lichttoten Teilflächen 5 auf der einen Seite der Mittelebene 6 kleiner als die entsprechenden Winkel auf der anderen Seite der Mittelebene 6.The interacting with an elongated light source 3 reflector surface 2 consists of reflecting partial surfaces 4 and arranged between them, due to their orientation at least essentially light-dead partial surfaces 5. The inclination of the respective partial surfaces is different and chosen so that the desired asymmetrical radiation characteristic results. The angles between the reflecting partial surfaces 4 and the light-dead partial surfaces 5 on one side of the central plane 6 are smaller than the corresponding angles on the other side of the central plane 6.

Im Mittelbereich des Reflektors sind an dessen Rückseite Verbindungsstege 14 angeformt, die einen Anschluß bzw. eine Verschraubung mit einer Trägerstruktur 8 ermöglichen, die bügelförmig ausgestaltet ist und vorzugsweise mehrere Kühlrippen 10 aufweist. Diese Trägerstruktur 8, an der auch die beidendigen Seitenscheiben 7 befestigt sind, kann auch mit einem Doppelfassungsträger ausgestattet sein, aber es ist auch möglich, die Fassungen an den Seitenscheiben 7 bzw. den zur Trägerstruktur 8 gehörenden seitlichen Tragbügeln 13 zu haltern.In the middle region of the reflector, connecting webs 14 are formed on the rear side thereof, which enable a connection or a screw connection to a support structure 8, which is designed in a bow-shaped manner and preferably has a plurality of cooling ribs 10. This support structure 8, to which the two-sided side windows 7 are also attached, can also be equipped with a double-frame support, but it is also possible to hold the versions on the side windows 7 or the side support brackets 13 belonging to the support structure 8.

Die Figur 2 zeigt die bügelartige Form der Trägerstruktur 8, innerhalb derer der gestufte Reflektor 1 sowie die Seitenscheiben 7 gelegen sind. Die Fassungen 12 für die Leuchte 3 bzw. die dem Doppelfassungsträger 15 zugeordneten Fassungsaufnahmebereiche sind schematisch dargestellt, und es ist auch zu erkennen, daß die Kühlrippen 10 unmittelbar an die Trägerstruktur 8 angeformt sind.FIG. 2 shows the bow-like shape of the support structure 8, within which the stepped reflector 1 and the side windows 7 are located. The sockets 12 for the lamp 3 or the socket receiving areas assigned to the double socket support 15 are shown schematically, and it can also be seen that the cooling fins 10 are molded directly onto the support structure 8.

Über geeignete Halteelemente, die über Rändelschrauben 11 mit den Tragbügeln 13 verschraubbar sind, wird eine Abdeck- oder Filterscheibe 9 gehaltert.A cover or filter disk 9 is held by means of suitable holding elements, which can be screwed to the carrying brackets 13 by means of knurled screws 11.

Bezüglich der Quererstreckung des Strahlers symmetrisch und bezüglich seiner Längserstreckung asymmetrisch ist an der Trägerstruktur 8 eine Kupplungs-Konushülse 16 vorgesehen, die mit einem Integral-Anschlußkopfteil 17 verbindbar ist. Dazu wird die Kupplungs-Konushülse 16 auf das komplementär gestaltete Anschlußkopfteil 17 geschoben und über eine Bajonettverbindung fixiert. Aufgrund dieser Ausgestaltung der Kupplungs-Konushülse 16 ist es möglich, den Strahler mit Trägerstrukturen zu koppeln, wie sie beispielsweise in der DE-A1 39 16 308 beschrieben sind.With regard to the transverse extension of the radiator symmetrically and asymmetrically with regard to its longitudinal extension, a coupling cone sleeve 16 is provided on the support structure 8, which can be connected to an integral connection head part 17. For this purpose, the coupling cone sleeve 16 is pushed onto the complementarily designed connection head part 17 and fixed via a bayonet connection. Due to this configuration of the coupling cone sleeve 16, it is possible to couple the radiator to support structures, such as are described, for example, in DE-A1 39 16 308.

Die Seitenscheiben 7 können an den Tragbügeln 13 so fixiert werden, daß zwischen diesen Seitenscheiben und dem Reflektor 1 ein geringer Spalt verbleibt, der zur Bildung eines optisch attraktiv geformten Lichtbandes führt und außerdem die Durchlüftung und damit Kühlung des Strahlers fördert.The side windows 7 can be fixed to the support brackets 13 so that a small gap remains between these side windows and the reflector 1, which leads to the formation of an optically attractively shaped light band and also promotes ventilation and thus cooling of the radiator.

Figur 3 zeigt eine vorteilhafte Ausführungsvariante der Erfindung, die es ermöglicht, gerichtetes Licht mit indirektem Licht zu kombinieren.Figure 3 shows an advantageous embodiment of the invention, which makes it possible to combine directed light with indirect light.

Dies ermöglicht eine Auflösung des Reflektors in mehrere reflektierende Teilflächen 4, die sich lamellenartig zwischen den beiden Seitenscheiben 7 erstrecken und vorzugsweise in Schlitzen dieser Seitenscheiben 7 gehaltert sind.This enables the reflector to be resolved into a plurality of reflecting partial surfaces 4 which extend in a lamella-like manner between the two side windows 7 and are preferably held in slots in these side windows 7.

Diese lamellenartigen reflektierenden Teilflächen 4 besitzen unterschiedliche Neigung, so daß eine asymmetrische Abstrahlung erzielt wird. Im dargestellten Ausführungsbeispiel ist in dem rechts von der Mittelebene 6 gelegenen Bereich eine relativ breite reflektierende Lamelle 4 vorgesehen, die sich jedoch nicht bis zur Mittelebene 6 erstreckt. In dem links von der Mittelebene 6 gelegenen Bereich sind zwei schmälere, jedoch vorzugsweise auch unterschiedlich breite reflektierende Lamellen 4 angeordnet, die mit der Längsmittelebene 6 einen spitzeren Winkel als die auf der anderen Seite gelegene breite Lamelle einschließen.These lamellar reflecting partial surfaces 4 have different inclinations, so that asymmetrical radiation is achieved. In the exemplary embodiment shown, a relatively wide reflective lamella 4 is provided in the area to the right of the central plane 6, but does not extend to the central plane 6. In the area to the left of the central plane 6, two narrower, but preferably also differently wide reflective slats 4 are arranged, which form a more acute angle with the longitudinal central plane 6 than the wide slat located on the other side.

Auf der Rückseite der reflektierenden Lamellen 4 ist mit Abstand zu diesen Lamellen ein die Rückwand des Strahlers bildender flächiger Reflektor 18 angeordnet, der aus einem Lochblech besteht. Dieser flächigere Reflektor 18 ist an Stäben 19 fixiert, die sich zwischen den Seitenscheiben 7 erstrecken.On the back of the reflective slats 4, at a distance from these slats, there is arranged a flat reflector 18 which forms the rear wall of the radiator and which consists of a perforated plate. This flat reflector 18 is fixed to rods 19 which extend between the side windows 7.

Durch Wahl des Abstandes, der Neigung und der Anzahl der reflektierenden Einzellamellen 4 läßt sich einerseits die Abstrahlcharakteristik auf einfache Weise beeinflussen, und zum anderen kann auf diese Weise vorgegeben werden, welcher Lichtanteil über die Rückseite des Strahlers in Form von indirektem Licht abgegeben wird.By selecting the distance, the inclination and the number of reflecting individual lamellae 4, on the one hand, the radiation characteristic can be influenced in a simple manner, and on the other hand it can be specified in this way which proportion of light is emitted via the back of the spotlight in the form of indirect light.

Vorzugsweise wird diese Ausführungsform eines Strahlers bzw. Strahlerkopfes mit sogenannten Energiesparlampen bestückt.This embodiment of an emitter or emitter head is preferably equipped with so-called energy-saving lamps.

Wie Figur 4 zeigt, ist dazu seitlich einer Seitenscheibe 7 ein Fassungsträger 20 vorgesehen, der vorzugsweise mit der Kupplungs-Konushülse 16 gegebenenfalls über zusätzliche mechanische Verbindungsteile zu einer Einheit zusammengefaßt ist, welche an einer Seitenscheibe 7 fixiert werden kann.As shown in FIG. 4, a mount carrier 20 is provided on the side of a side window 7, which is preferably combined with the coupling cone sleeve 16, optionally via additional mechanical connecting parts, to form a unit which can be fixed to a side window 7.

Auf der dem Fassungsträger 20 gegenüberliegenden Seite ist in der dortigen Seitenwand 7 ein vorzugsweise über Rastelemente gehaltertes Steckteil 21 vorgesehen, das mit Lampenführungselementen 22 und vorzugsweise mit einem Halteorgan für die Deck- oder Filterscheibe 9 versehen ist. Dieses Steckteil 21 kann nach Entriegelung einfach abgezogen werden, worauf es möglich ist, die Deck- oder Filterscheibe 9 zu entfernen und auch auf einfache Weise einen Lampenwechsel vorzunehmen.On the side opposite the frame carrier 20, there is provided in the side wall 7 there a plug-in part 21 which is preferably held via latching elements and which is provided with lamp guide elements 22 and preferably with a holding element for the cover or filter disk 9. This plug-in part 21 can be easily removed after unlocking, whereupon it is possible to remove the cover or filter disc 9 and to change the lamp in a simple manner.

Die Seitenscheiben 7 können als lichtdurchlässige Mattscheiben ausgebildet werden, wobei Fassungsträger 20 und Steckteil 21, die nicht lichtdurchlässig sind, gleichzeitig an den Stellen höchster Lichtstärke Ausblendelemente bilden.The side windows 7 can be designed as translucent ground glass screens, the mount carrier 20 and plug-in part 21, which are not translucent, simultaneously form masking elements at the points of maximum light intensity.
