Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Lichtlenkprofils, das im Querschnitt wenigstens drei Eckpunkte aufweist, zwischen denen sich gerade oder gekrümmte Flächen befinden.The invention relates to a method for producing a Light-guiding profile that has at least three corner points in cross-section has between which there are straight or curved surfaces are located.
Solche Lichtlenkprofile sind bekannt, z. B. aus dem Artikel "Die solar-intelligente Fassade" in raum & zeit, Nr. 45/90, Seiten 24-31. Sie ermöglichen es unter anderem, sowohl in einem über solche Profile ausgeleuchteten Innenraum als auch in einem Außenraum, von dem aus eine Lichtquelle auf die Lichtlenkprofile scheint, die Blendung erheblich zu reduzieren oder gar zu eliminieren.Such light directing profiles are known, e.g. B. from the article "The solar intelligent facade" in raum & zeit, No. 45/90, Pages 24-31. Among other things, they enable both an interior illuminated by such profiles as well in an outdoor space from which a light source shines on the Light directing profiles seem to reduce glare considerably or even to eliminate them.
In der Figur ist eine Prinzip-Anordnung dargestellt, die ver anschaulicht, wie die Sonnenstrahlen durch solche bekannten Lichtlenkprofile geführt werden. Die Sonne wird hierbei durch einen Flächenstrahler 1 symbolisiert, der zwei Lichtlenkprofi le 2, 3 anstrahlt. Hinter diesen Lichtlenkprofilen 2, 3 be findet sich der zu beleuchtende Raum 4. Es versteht sich, daß das Lichtlenksystem in der Regel mehr als nur zwei überein ander angeordnete Lichtlenkprofile 2, 3 aufweist. Die gezeig ten Lichtlenkprofile weisen jeweils drei Eckpunkte 17, 18, 28 bzw. 19, 24, 30 auf sowie konkav gekrümmte Flächen 21, 31, 32 bzw. 21, 33, 60.In the figure, a principle arrangement is shown, which illustrates how the sun's rays are guided through such known light-guiding profiles. The sun is symbolized here by a surface radiator 1 , which illuminates two Lichtlenkprofi le 2 , 3 . Behind these light directing profiles 2 , 3 there is the room 4 to be illuminated. It goes without saying that the light control system generally has more than just two superimposed light control profiles 2 , 3 . The shown light guide profiles each have three corner points 17 , 18 , 28 and 19 , 24 , 30 and concave curved surfaces 21 , 31 , 32 and 21 , 33 , 60 .
An dem Flächenstrahler 1 sind mehrere Punkte 5 bis 10 gekenn zeichnet, die stellvertretend für alle Punkte der strahlenden Fläche stehen. Von diesen Punkten 5 bis 10 gehen nach allen Richtungen rechts vom Flächenstrahler 1 Lichtstrahlen aus, die sich - da Beugungserscheinungen nicht betrachtet werden sollen - geradlinig ausbreiten. Von diesen unendlich vielen Licht strahlen sind einige wenige in der Figur dargestellt, um das Prinzip der Lichtlenkung und Schattenbildung deutlich zu ma chen. Beispielsweise gehen von Punkt 5 vier verschiedene Lichtstrahlen 11 bis 13 und 15 aus, von denen der Lichtstrahl 11 den oberen Eckpunkt 17 des Lichtlenkprofils 2 tangiert. Ein zweiter Lichtstrahl 12 tangiert einen zweiten Eckpunkt 18 desselben Lichtlenkprofils 2, während ein dritter Lichtstrahl 13 einen oberen Eckpunkt 19 des unteren Lichtlenkprofils 3 tangiert und ein vierter Lichtstrahl 15 einen zweiten Eckpunkt 24 des unteren Lichtlenkprofils 3 tangiert. On the surface radiator 1 , several points 5 to 10 are marked, which represent all points of the radiating surface. From these points 5 to 10 light rays emanate in all directions to the right of the surface radiator 1 , which - since diffraction phenomena are not to be considered - spread in a straight line. A few of these infinite rays of light are shown in the figure to make the principle of light control and shadow formation clear. For example, point 5 has four different light beams 11 to 13 and 15 , of which the light beam 11 affects the upper corner point 17 of the light guide profile 2 . A second light beam 12 affects a second corner point 18 of the same light guide profile 2 , while a third light beam 13 affects an upper corner point 19 of the lower light guide profile 3 and a fourth light beam 15 affects a second corner point 24 of the lower light guide profile 3 .
Das Blendungsproblem läßt sich nun mit einem Lichtlenkprofil der eingangs genannten Art lösen, so daß vorteilhaft schon in kurzer Distanz hinter der Lichtdurchtrittsstelle eine gleich mäßige Ausleuchtung eines Innenraums gewährleistet ist, wobei Blendungen im Innenraum und Außenraum reduziert bzw. vermieden werden. Allerdings ist die Herstellung solcher Lichtlenkprofi le aufwendig und teuer.The glare problem can now be solved with a light control profile solve the type mentioned, so that advantageous already in short distance behind the light passage point is the same moderate illumination of an interior is guaranteed, whereby Glare in the interior and exterior reduced or avoided will. However, the manufacture of such light directing professionals le complex and expensive.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Lichtlenkprofils, das im Querschnitt wenigstens drei Eckpunkte aufweist, zwischen denen sich gerade oder gekrümmte Flächen befinden, anzugeben, welches einfach und damit kostengünstig anwendbar ist.The present invention therefore lies the task of a method for producing a Light-guiding profile that has at least three corner points in cross-section has between which there are straight or curved surfaces are to specify which is simple and therefore inexpensive is applicable.
Die Aufgabe wird gelöst von einem Verfahren zur Herstellung eines Lichtlenkprofils der genannten Art, bei welchem das Lichtlenkprofil aus einem massiven Metalldraht durch Walzen hergestellt wird. Dieses Herstellungsverfahren ermöglicht die kostengünstige Herstellung qualitativ hochwertiger Lichtlenk profile und hat gegenüber anderen Herstellungsverfahren, ins besondere spanenden Verfahren, unter anderem den Vorteil, daß der Faserverlauf des Materials erhalten bleibt, wodurch die Querwirkung verringert wird. Zudem handelt es sich um eine praktisch verlustfreie Werkstoffverarbeitung, und je nach verwendetem Metall kann sich die Festigkeit beim Kaltumformen wesentlich erhöhen. Gegenüber der spanenden Formgebung ergeben sich mit dem erfindungsgemäßen Verfahren kürzere Fertigungs zeiten und insbesondere die Möglichkeit zur Herstellung ein baufertiger Teile mit hoher Oberflächengüte und sehr kleinen Maßtoleranzen.The object is achieved by a production method a light control profile of the type mentioned, in which the Light directing profile made from a solid metal wire by rolling will be produced. This manufacturing process enables Inexpensive manufacture of high quality light control profiles and has compared to other manufacturing processes, ins special machining processes, including the advantage that the grain of the material is retained, which means that Cross effect is reduced. It is also a practically lossless material processing, and depending on The metal used can increase the strength during cold forming increase significantly. Compared to the cutting shape shorter manufacturing process with the inventive method times and in particular the possibility of production ready-to-build parts with high surface quality and very small Dimensional tolerances.
In vorteilhafter Weiterbildung des Verfahrens wird das Licht lenkprofil aus einem Metalldraht hergestellt, dessen Durch messer kleiner als 6,5 mm ist.In an advantageous development of the method, the light Steering profile made of a metal wire, the through knife is smaller than 6.5 mm.
Je nach Einsatzort des herzustellenden Lichtlenkprofils kann der Fachmann verschiedene Ausgangsmaterialien bei der Herstel lung verwenden, wobei es sich insbesondere massiver Stahldraht sowie Aluminiumdraht bewährt haben.Depending on the location of the light control profile to be manufactured the expert various starting materials in the manufacture use lung, in particular solid steel wire as well as aluminum wire have proven.
Bei einer bevorzugten Durchführung des Verfahrens wird der Draht in ein Lichtlenkprofil umgeformt, dessen am weitesten voneinander entfernte Eckpunkte höchstens 5 mm auseinanderlie gen.In a preferred implementation of the method Wire formed into a light directing profile, the furthest of which Corner points at a distance of 5 mm apart from each other gene.
Je nach Anwendungszweck des herzustellenden Lichtlenkprofils kann es zweckmäßig sein, das Verfahren derart durchzuführen, daß wenigstens eine von insgesamt drei Flächen des Lichtlenk profiles konkav gekrümmt ausgeformt wird. Auch ist es möglich, wenigstens ein Teilstück einer der Flächen des Lichtlenkpro files zu verspiegeln.Depending on the application of the light control profile to be produced it may be expedient to carry out the method in such a way that at least one of a total of three surfaces of the light guide profiles are formed concavely curved. It is also possible at least a portion of one of the surfaces of the Lichtlenkpro mirror files.
Das erfindungsgemäße Verfahren erlaubt die Herstellung unter schiedlicher Lichtlenkprofile, die jeweils optimal an den jeweiligen Einsatzzweck angepaßt sind, wobei es möglich ist, mehrere Lichtlenkprofile zu einem Lichtlenksystem zu kombinie ren.The method according to the invention allows production under different light directing profiles, each optimally adapted to the are adapted to the respective application, it being possible to combine several light control profiles into one light control system ren.
