Abstract

A transparent or translucent glass or plastic pane as part of a lamp or other lighting device is provided with a structured surface. A multitude of micro elements in the shape of truncated cones create a particular light reflecting effect. The opening angle of the lighting device is restricted by covering the pane and forcing the beams to enter only trough the top of the cones.

Description

Die Erfindung betrifft eine Vorrichtung zur Richtung des Lichtes beliebiger Leuchtmittel auf der Basis von Brechung und Reflexion mit einer sich flächig erstreckenden, zum Teil transparenten und zum Teil lichtundurchlässigen Scheibe vorgegebener Dicke, wobei das Licht an einer ersten der beiden Oberflächen in die Scheibe eintritt und an der zweiten Scheibenoberfläche austritt, und mindestens eine der beiden Oberflächen mit einer mikrostrukturierten Oberfläche versehen ist, die die Abstrahlungsrichtung des durchtretenden Lichtes derart beeinflusst, dass diese parallel zur Oberflächennormale verläuft. Dies wird erreicht indem die verwendete Mikrooptik aus stumpfen Kegeln besteht, die die einfallenden Lichtstrahlen durch Brechung und Totalreflexion bevorzugt in eine bestimmte Richtung streuen.The The invention relates to a device for the direction of the light of any Illuminant based on refraction and reflection with a flat extending, partly transparent and partially opaque disc predetermined thickness, wherein the light on a first of the two surfaces in the disc enters and exits at the second disc surface, and providing at least one of the two surfaces with a microstructured surface is the direction of emission of the transmitted light in such a way influences that it runs parallel to the surface normal. This is achieved by the used micro-optics blunt cones consists of the incident light rays by refraction and total reflection preferably sprinkle in a certain direction.

Derart optisch wirksame Oberflächen werden verwendet, um den Öffnungswinkel von Leuchtmitteln, insbesondere von Leuchten zu beschränken. Dadurch wird eine Entblendung gemäß einschlägiger Arbeitsvorschriften gewährleistet.so optically effective surfaces are used to the opening angle of bulbs, in particular of luminaires. Thereby becomes a glare control in accordance with the relevant work regulations guaranteed.

Die erfindungsgemäße Kegelstruktur mit dem erfindungsgemäßen Kegelwinkel zeigt auch für schrägen Lichteinfall die oben beschriebene charakteristische Streuung. Erfindungsgemäß wird die erste Plattenoberfläche derart abgedeckt, dass nur die Kegelenden offen bleiben. Dies wird realisiert durch verspiegeln oder lichtundurchlässig beschichten der Kegelzwischenräume oder durch auflegen einer passend perforierten Folie.The Cone structure according to the invention with the cone angle according to the invention also shows for oblique incidence of light the characteristic scattering described above. According to the invention first plate surface Covered so that only the cone ends remain open. this will realized by mirroring or opaque coating of the cone interspaces or by placing a suitably perforated foil.

Der Erfindung liegt somit die Aufgabe zugrunde, eine optische Oberfläche zur Richtung des Lichtes verschiedener Leuchtmittel auf Basis von Brechung und Totalreflexion, oder einer Mischung beider Effekte, mit großer Effizienz bereitzustellen.Of the Invention is therefore the object of an optical surface for Direction of the light of different bulbs based on refraction and total reflection, or a mixture of both, with great efficiency provide.

In Zeichnung 1 und 2 wird die erfindungsgemäße Mikrostruktur dargestellt. 3a zeigt senkrecht, 3b und 3c schräg einfallenden Strahlengang.In drawing 1 and 2 the microstructure according to the invention is shown. 3a shows vertically, 3b and 3c obliquely incident beam path.

Die erfindungsgemäße Platte kann aus transparenten, thermoplastischen Kunststoffen wie Polycarbonat, PMMA oder PE im Heißprägeverfahren oder Gießverfahren hergestellt werden.The plate according to the invention can be made of transparent, thermoplastic plastics such as polycarbonate, PMMA or PE in the hot stamping process or casting process getting produced.
