Abstract

Device for deblinding an illuminating device is made from a thermoplastic material produced by hot embossing or injection molding. The thermoplastic material is provided with a reflecting surface.

Description

Die Erfindung betrifft eine Vorrichtung zur Entblendung eines Leuchtmittels auf der Basis der Reflexion von Licht mit einer sich flächig erstreckenden Platte vorgegebener Dicke, wobei das Licht durch Öffnungen in dieser Platte direkt durch diese Platte hindurchtreten kann oder an den idealerweise gleichmäßig verteilten, lichtrichtenden spiegelnden Oberflächen der Öffnungen reflektiert wird, so dass nach dem Lichtaustritt keine unerwünschten Lichtaustrittswinkel auftreten.The invention relates to a device for glare control of a lamp based on the reflection of light with a flat extending plate of predetermined thickness, the light through openings in this plate can pass directly through this plate or ideally evenly distributed, light-directing reflecting surfaces of the openings are reflected, so that after the light emission no unwanted light emission angles occur.

Die entsprechende Arbeitsvorschriften zur Entblendung von Leuchtmitteln, insbesondere Lampen, beschreiben den Lichtaustritt an leuchtenden Vorrichtungen und dienen dazu den gesetzlichen Rahmen zu schaffen, um Blendung eines Betrachters zu vermeiden und Sehkomfort zu gewährleisten.The corresponding work regulations for glare control of lamps, in particular lamps the light exit on luminous devices and serve the create legal framework to dazzle a viewer avoid and ensure visual comfort.

Um eine gute Entblendung zu erreichen, sind verschiedene Möglichkeiten bekannt. So gibt es spiegelnde Lamellen aus polierten oder tiefgezogenen Metallen und bedampften oder lackierten Kunststoffen. Diese makroskopisch, mehrere Zentimeter großen Spiegel sind häufig rasterartig aufgebaut, so dass aus zwei oder mehreren Reihen und zwei oder mehreren Spalten eine offene Leuchtenabdeckung entsteht, die gute Lichtrichtung gewährleistet, aber hohe Leuchtenaufbauten erzeugt. Für Leuchten die auf Ständern vornehmlich neben Schreibtischen aufgestellt werden sind solche Spiegellamellen aufgrund ihrer hohen Bauhöhe ungeeignet.To achieve good glare control, are different options known. There are reflective slats made of polished or deep-drawn metals and steamed or painted plastics. This macroscopic, several centimeters tall Mirrors are common structured like a grid, so that from two or more rows and two or more columns create an open luminaire cover, the good direction of light ensures but produces high luminaire structures. For lights mainly on stands Such mirror slats are placed next to desks due to their high height not suitable.

Hier sind transparente Abdeckungen aus Kunststoff oder Glas zur Verminderung des Öffnungswinkels bekannt, die aber in den meisten Fällen die gültige Arbeitsplatzvorschrift nicht erreichen. Ebenso werden Lochbleche eingesetzt, mit denen eine gleichmäßig hohe Schwächung der Leuchtdichten erreicht wird.Here are transparent covers known from plastic or glass to reduce the opening angle, the but in most cases the valid one Do not reach workplace regulation. Likewise, perforated sheets used with which a uniformly high weakening of the Luminance is achieved.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung zur Entblendung eines Leuchtmittels auf Basis von Reflexion bereitzustellen und gleichzeitig geringe Materialdicken einzusetzen, um flache Leuchtenaufbauten zu gewährleisten.The invention is therefore the object based on a device for glare control of a lamp To provide the basis of reflection and at the same time low material thickness to ensure flat luminaire structures.

Erfindungsgemäß wird dieses durch eine flächig ausgedehnte Platte erreicht, die vornehmlich mit kegelstumpfförmigen, pyramidenstumpfförmigen oder im Querschnitt sich in Lichtrichtung im Durchmesser vergrößernden Öffnungen versehen ist, wobei die Öffnungen quadratisch oder hexagonal nebeneinander angeordnet sind.According to the invention, this is extended by a flat area Plate reached, mainly with frustoconical, truncated pyramid or openings that increase in diameter in cross-section in the direction of light is provided, the openings are arranged square or hexagonally next to each other.

Diese Platte wird aus thermoplastischen Kunststoffen wie Polycarbonat, PMMA oder PE im Heißprägeverfahren hergestellt, um große Flächen bereitstellen zu können. Große Flächen sind im Spritzverfahren nicht herstellbar.This plate is made of thermoplastic materials such as polycarbonate, PMMA or PE manufactured in a hot stamping process size Provide space to be able to. Size surfaces cannot be produced by spraying.

Die so entstandene Abdeckung wird durch Vakuumaufdampfverfahren oder Lackierung mit einer reflektierenden Schicht versehen.The resulting cover will by vacuum evaporation or painting with a reflective Layer.

Die erfindungsgemäße Abdeckung besitzt durch das vollständige Ausfüllen mit Material in den Bereichen zwischen den optisch wirksamen Öffnungen große Steifigkeit. Strukturen, die z.B. im Tiefziehverfahren hergestellt worden sind und nur die reflektierte Wandung als Material bereitstellen, sind nicht selbsttragend und hängen, eingebaut und befestigt an den Rändern, mittig durch.The cover according to the invention has the whole To complete with material in the areas between the optically effective openings size Rigidity. Structures that e.g. manufactured using the deep-drawing process and only provide the reflected wall as material, are not self-supporting and hang, installed and attached to the edges, in the middle.

Der Anteil der in den Leuchtmittelraum zurückreflektierten Strahlung wird weiter genutzt, indem die nach oben offene Leuchte einen indirekten Lichtanteil an darüberliegenden Gebäudedecken erzeugt oder die reflektierte Strahlung wiederum durch geeignete Reflektoren auf die erfindungsgemäße Abdeckung gelenkt wird.The proportion of in the illuminant room reflected back Radiation is used further by the lamp open at the top an indirect light component on the building ceilings above generated or the reflected radiation in turn by suitable Reflectors is directed onto the cover according to the invention.

Der Querschnitt einer Ausführungsform der erfindungsgemäßen Abdeckung ist in 1 dargestellt. Man erkennt die auf die Abdeckung auftreffenden Strahlengänge 1, die direkt durch die Abdeckung gehenden Strahlengänge 3 und die an den Mikrospiegel-Reflexionsoberflächen 6 reflektierten Strahlengänge 4. Die Strahlenverläufe 2 stellen den blendfreien Lichtausfall dar, wobei keine Lichtstrahlen im Winkelbereich 7 auftreten. Die erfindungsgemäße Abdeckung hat eine Dicke 8, die im Millimeterbereich liegt. 2a und 3a zeigen die Oberseite verschiedener Ausführungsformen der erfindungsgemäßen Abdeckung 9 und 10, an der die vom Leuchtmittel ausgehenden Lichtstrahlen durchtreten oder reflektiert werden. 2b und 3b zeigen die Unterseite verschiedener Ausführungsformen der erfindungsgemäßen Abdeckung 9 und 10 , an der die Lichtstrahlen blendfrei austreten.The cross section of an embodiment of the cover according to the invention is in 1 shown. You can see the beam paths hitting the cover 1 , the beam paths going directly through the cover 3 and those on the micromirror reflection surfaces 6 reflected beam paths 4 , The rays 2 represent glare-free light loss, with no light rays in the angular range 7 occur. The cover according to the invention has a thickness 8th , which is in the millimeter range. 2a and 3a show the top of various embodiments of the cover according to the invention 9 and 10 , at which the light rays emanating from the illuminant pass or are reflected. 2 B and 3b show the underside of various embodiments of the cover according to the invention 9 and 10 where the light rays emerge without glare.
