Der Erfindung liegt die Aufgabe zugrunde, einen Vorsatz für freistrahlende Miniaturreflektoren anzugeben, der unmittelbar an dem Miniaturreflektor befestigbar ist und leicht ausgewechselt werden kann.The invention has for its object to provide an attachment for free-radiating miniature reflectors that can be attached directly to the miniature reflector and can be easily replaced.
Gegenstand der Erfindung und Lösung dieser Aufgabe ist ein Vorsatz, der gekennzeichnet ist durchThe object of the invention and solution to this problem is an intention, which is characterized by
ein am Reflektorrand des Miniaturreflektors auf¬ liegendes Auflageelement,a support element lying on the edge of the miniature reflector,
mindestens zwei an das Auflageelement angeformte Klemmelemente, die den Reflektorrand hinterfassen, undat least two clamping elements molded onto the support element, which grip the reflector edge, and
mindestens ein an das Auflageelement angeformtes Lichtlenkelement zur Beeinflussung des Lichtaustritts aus dem Miniaturreflektor,at least one light-guiding element molded onto the support element for influencing the light emission from the miniature reflector,
wobei das Auflageelement, die Klemmelemente und die Licht¬ lenkelemente Bestandteile eines aus einem Stück gefertigten, einteiligen Vorsatzelementes sind. Das Vorsatzelement besteht aus einem temperaturbeständigen, nichtelastischen, jedoch flexiblen Material und ist durch seine Klemmelemente formschlüssig am Reflektorrand festgehalten. Sämtliche Funktionselemente (Halteklammern, Scharniere, Lamellen, Klappen) sind aus dem Bauteil selbst herausgebildet. Vorzugsweise ist das Vorsatzelement als Stanz- und Biegeteil aus einem rostfreien Federstahlblech gefertigt und mit einer mattschwarzen Oberfläche versehen.the support element, the clamping elements and the light-directing elements being components of a one-piece attachment element made from one piece. The attachment element consists of a temperature-resistant, non-elastic, but flexible material and is held in a form-fitting manner by the clamping elements on the edge of the reflector. All functional elements (retaining clips, hinges, slats, flaps) are made from the component itself formed. The attachment element is preferably manufactured as a stamped and bent part from a stainless spring steel sheet and is provided with a matt black surface.
Das erfindungsgemäße Vorsatzelement kann mit einem sehr geringen Gewicht gefertigt werden, so daß die üblichen Verbindungen zwischen dem Miniaturreflektor und der Lampenfassung das Zusatzgewicht ohne weiteres aufnehmen kann. Das Gewicht des Vorsatzelementes ist regelmäßig kleiner als das Gewicht des Reflektors mit Leuchtmittel.The attachment element according to the invention can be manufactured with a very low weight, so that the usual connections between the miniature reflector and the lamp holder can easily accommodate the additional weight. The weight of the front element is regularly smaller than the weight of the reflector with illuminant.
Das erfindungsgemäße Vorsatzelement ist kostengünstig, funktionssicher und in der Handhabung einfach. Es kann ohne Vorkenntnisse werkzeuglos angebracht und wieder entfernt werden. Die Reinigung ist einfach. Der niedrige Aufwand wirkt sich sowohl in der Anschaffung als auch bei eventuellen Beschädigungen oder bei Verlust positiv aus. Das erfindungsgemäße Vorsatzelement eignet sich auch für ein müheloses Nachrüsten bei freistrahlenden Miniatur- reflektoren.The attachment element according to the invention is inexpensive, reliable and easy to use. It can be attached and removed without tools without prior knowledge. Cleaning is easy. The low effort has a positive effect both in terms of the purchase as well as any damage or loss. The attachment element according to the invention is also suitable for effortless retrofitting in free-radiating miniature reflectors.
Für die weitere Ausgestaltung des erfindungsgemäßen Vorsatzelementes ergeben sich verschiedene Möglichkeiten. Nach einer bevorzugten Ausführungsform ist das Auflage- element ein Auflagering, an den winkelförmig abgebogene Klemmelemente angeformt sind. Zweckmäßig sind die Klemm¬ elemente als Bügel ausgebildet, die ein Ringsegment des Reflektorrandes hinterfassen. Eine besonders einfache und sichere Rastung ergibt sich insbesondere, wenn die Bügel bogenförmig gekrümmt sind und nahe ihren Anschlußstegen gegen die Unterseite des Reflektorrandes gerichtete Vor¬ sprünge aufweisen.There are various possibilities for the further configuration of the attachment element according to the invention. According to a preferred embodiment, the support element is a support ring, on which angularly bent clamping elements are formed. The clamping elements are expediently designed as brackets which enclose a ring segment of the reflector edge. A particularly simple and safe latching results in particular if the brackets are curved in an arc and close to their connecting webs have projections directed towards the underside of the reflector edge.
In bezug auf die Lichtlenkelemente ergeben sich viel- fältige Möglichkeiten der Gestaltung. Für die Praxis von besonderer Bedeutung sind Lichtklappen zur Ausblendung bestimmter Bereiche aus gestalterischen Gründen sowie Lichtlenklamellen zur Vermeidung von Blendung. In weiterer Ausgestaltung lehrt die Erfindung, daß mindestens zwei Lichtklappen durch biegeverformbare Stege an den Auflage¬ ring angeschlossen sind oder daß an den Auflagering Licht¬ lenklamellen angeschlossen sind, wobei die Lichtlenk¬ lamellen durch Stege mit dem Auflagering verbunden und zur Auflagefläche rechtwinklig abgebogen sind. Es können zwei oder mehr parallel angeordnete Lichtlenklamellen vor¬ gesehen sein. Alternativ können ferner mindestens drei Lichtlenklamellen in radialer Anordnung vorgesehen sein, wobei die Lichtlenklamellen mittig, beispielsweise durch eine Verbindungsscheibe, einstückig miteinander verbunden sind.With regard to the light directing elements, there are many design options. Of particular importance in practice are light flaps to hide certain areas for design reasons and light deflection slats to avoid glare. In a further embodiment, the invention teaches that at least two light flaps are connected to the support ring by bend-deformable webs or that light guide lamellae are connected to the support ring, the light guide lamellae being connected to the support ring by webs and bent at right angles to the support surface. Two or more light deflection slats arranged in parallel can be provided. Alternatively, at least three light-guiding slats can also be provided in a radial arrangement, the light-guiding slats being integrally connected to one another in the center, for example by a connecting disk.
Eine besonders bevorzugte Ausführung der Erfindung ist dadurch gekennzeichnet, daß zwei Lichtklappen an gegen¬ überliegenden Umfangsabschnitten des Auflageringes ange- ordnet sind, daß die Klemmelemente unter einem rechten Winkel dazu am Umfang des Auflagerings positioniert sind und daß die Lichtklappen jeweils durch zwei biegeverform¬ bare Stege mit dem Auflagering verbunden sind, wobei der Abstand zwischen den Stegen größer ist, als die Breite der Klemmelemente und dadurch ein weiteres Vorsatzelement aufsteckbar ist, dessen mit dem ersten Vorsatzelement identisch ausgeführten Klemmelemente in den Freiraum zwischen den Stegen einführbar sind und den Reflektorrand hinterfassen. Vielfältige Kombinationen sind möglich, insbesondere können Vorsatzelemente mit Lichtklappen untereinander sowie auch Vorsatzelemente mit Lichtklappen und Lichtlenklamellen kombiniert werden.A particularly preferred embodiment of the invention is characterized in that two light flaps are arranged on opposite circumferential sections of the support ring, that the clamping elements are positioned at a right angle to the circumference of the support ring and that the light flaps each have two bend-deformable webs are connected to the support ring, the distance between the webs being greater than the width of the clamping elements and thereby a further attachment element can be plugged on, the clamping elements of identical design to the first attachment element can be inserted into the free space between the webs and grasp the reflector edge. Various combinations are possible, in particular attachment elements with light flaps can be combined with one another, as well as attachment elements with light flaps and light deflection slats.
Die zuvor beschriebenen Ausgestaltungen weisen stets einen Auflagering als Auflageelement auf. Die ringförmige Aus¬ gestaltung des Auflageele entes ist jedoch nicht zwingend. Eine alternative Ausführung der Erfindung sieht Licht¬ lenklamellen vor, die einstückig durch mindestens einen Steg miteinander verbunden sind und mit ihrem reflektor- außenseitigen Lamellenende auf dem Reflektorrand auf¬ liegen, wobei an den Lamellenenden Haltenasen angeformt sind, die den Reflektorrand hinterfassen.The embodiments described above always have a support ring as a support element. However, the ring-shaped configuration of the support element is not mandatory. An alternative embodiment of the invention provides light-guiding lamellae which are connected to one another in one piece by at least one web and rest on the reflector edge with their lamella end on the outside of the reflector, holding lugs being formed on the lamella ends, which reach behind the reflector edge.
Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlich erläutert. Es zeigen schematisch und in perspektivischer DarstellungIn the following, the invention is explained in detail with reference to a drawing that shows only one exemplary embodiment. They show schematically and in perspective

Die Figuren zeigen Lichtlenkungsvorsätze, die jeweils auf einem Miniaturreflektor 1 mit Leuchtmittel 2, integrierter Abdeckscheibe 3 und Rand 4 befestigt sind. Sie weisen ein am Reflektorrand 4 des Miniaturreflektors 1 aufliegendes Auflageelement 5, mindestens zwei an das Auflageelement 5 angeformte Klemmelemente 6, die den Reflektorrand 4 hinterfassen, und mindestens ein an das Auflageelement 5 angeformtes Lichtlenkelement 7, 8 zur Beeinflussung des Lichtaustritts aus dem Minireflektor 1 auf. Das Auflage¬ element 5, die Klemmelemente 6 und die Lichtlenkelemente 7, 8 bilden dabei stets ein aus einem Stück gefertigtes einteiliges Vorsatzelement 9. Die Vorsatzelemente 9 sind einteilige Stanz- und Biegeteile, die im Ausführungs¬ beispiel aus einem rostfreien Federstahlblech gefertigt sind und eine mattschwarze Oberfläche aufweisen.The figures show light directing attachments, each of which is attached to a miniature reflector 1 with illuminant 2, integrated cover plate 3 and edge 4. They have a support element 5 resting on the reflector edge 4 of the miniature reflector 1, at least two clamping elements 6 molded onto the support element 5, which grip the reflector edge 4, and at least one light-guiding element 7, 8 molded onto the support element 5 for influencing the light exit from the mini reflector 1 . The support element 5, the clamping elements 6 and the light directing elements 7, 8 always form a one-piece attachment element 9 made from one piece. The attachment elements 9 are one-piece stamped and bent parts, which in the embodiment are made of a stainless spring steel sheet and one have a matt black surface.
Den Fig. 1 bis 3 entnimmt, daß das Auflageelement 5 ein Auflagering ist, an den winkelförmig abgebogene Klemm- elemente 6 angeformt sind. Die Klemmelemente 6 sind als Bügel ausgebildet, die jeweils ein Ringsegment des Reflektorrandes 4 hinterfassen und das Vorsatzelement 9 dadurch formschlüssig am Reflektorrand 4 festhalten. Man erkennt auch, daß die Bügel bogenförmig gekrümmt sind und nahe ihren Anschlußstegen gegen die Unterseite des Reflektorrandes 4 gerichtete Vorsprünge 10 aufweisen.1 to 3 that the support element 5 is a support ring on the angularly bent clamping elements 6 are formed. The clamping elements 6 are designed as brackets, each of which grips a ring segment of the reflector edge 4 and thereby hold the attachment element 9 positively on the reflector edge 4. It can also be seen that the brackets are curved in an arc and have projections 10 directed towards the underside of the reflector edge 4 near their connecting webs.
Die Lichtlenkelemente können unterschiedlich gestaltet sein. Die Fig. 1 zeigt eine Ausführungsform mit zwei seit¬ lichen Lichtklappen 7, die durch Stege 11 an den Auflage¬ ring 5 angeschlossen sind. Die Stege 11 sind biegever- formbar und erfüllen die Funktion von Biegescharnieren.The light directing elements can be designed differently. 1 shows an embodiment with two lateral light flaps 7 which are connected to the support ring 5 by webs 11. The webs 11 are bendable and fulfill the function of bending hinges.
Die Fig. 2 und 3 betreffen Vorsatzelemente 9 mit Licht¬ lenklamellen 8. Die Lichtlenklamellen 8 sind durch Stege mit dem Auflagering 5 verbunden und zur Auflagefläche rechtwinklig abgebogen. Dabei können drei oder mehr Licht¬ lenklamellen in radialer Anordnung vorgesehen sein, wobei die Lichtlenklamellen mittig durch eine Verbindungsscheibe 12 einstückig miteinander verbunden sind (Fig. 2). Die Fig. 3 zeigt eine Ausführungsform mit parallel ange¬ ordneten Lichtlenklamellen 8, die insofern ein Parallel¬ raster bilden.2 and 3 relate to attachment elements 9 with light-guiding blades 8. The light-guiding blades 8 are connected to the support ring 5 by webs and bent at right angles to the support surface. In this case, three or more light-guiding lamellae can be provided in a radial arrangement, the light-guiding lamellae being integrally connected to one another in the center by a connecting disk 12 (FIG. 2). 3 shows an embodiment with light deflection slats 8 arranged in parallel, which in this respect form a parallel grid.
Den Fig. 4 und 5 entnimmt man, daß Vorsatzelemente 9 mit seitlichen Lichtklappen untereinander sowie auch mit einem Vorsatzelement, welches Lichtlenklamellen 8 aufweist, kombiniert werden können. Die Kombination von zwei Vorsatzelementen 9 ist möglich, wenn der Abstand zwischen den Stegen 11 der Lichtklappe 7 größer ist als die Breite der Klemmelemente 6. Dadurch ist ein weiterer Vorsatz aufsteckbar, indem die Klemmelemente 6 dieses Vorsatzes in den Freiraum zwischen den Stegen 11 eingeführt werden und dann den Reflektorrand 4 hinterfassen.4 and 5 it can be seen that attachment elements 9 with lateral light flaps can be combined with one another and also with an attachment element which has light deflection slats 8. The combination of two attachment elements 9 is possible if the distance between the webs 11 of the light flap 7 is larger than the width of the clamping elements 6. This allows a further attachment to be plugged on by inserting the clamping elements 6 of this attachment into the space between the webs 11 and then grasping the reflector edge 4.
Bei der in Fig. 6 dargestellten Ausführung weist das Vorsatzelement 9 Lichtlenklamellen 8 auf, die einstückig durch mindestens einen Steg, z. B. in Form einer Verbindungsscheibe 12, miteinander verbunden sind und mit ihrem reflektoraußenseitigen Lamellenende auf dem Reflektorrand aufliegen. Die Lamellenenden bilden das Auflageelement 5. An den Lamellenenden sind als Klemm¬ elemente Haltenasen 13 angeformt, die den Reflektorrand 4 hinterfassen und das Vorsatzelement 9 formschlüssig am Reflektorrand 4 festhalten. In the embodiment shown in FIG. 6, the attachment element 9 has light-guiding slats 8 which are integrally formed by at least one web, e.g. B. in the form of a connecting disc 12, are connected to each other and rest with their reflector outside lamella end on the reflector edge. The lamella ends form the support element 5.
