Abstract

The system has a laminar extending plate e.g. micro-structured prism plate (2), of preset thickness, where the plate is made of transparent plastic or glass. The plate has two surfaces, where one of the two surfaces is provided with an optically effective microstructure, which has a set of micro units. The micro-units are tilted in a symmetric axis related to a surface-normal of the laminar plate. The micro units are designed in the form of cones, pyramids, lenses or prisms. Tilting angle of individual micro units is varied between the symmetric axis and the surface-normal.

Description

Die Erfindung betrifft eine Vorrichtung zur Richtung des Lichtes beliebiger Leuchtmittel auf der Basis von Brechung mit einer sich flächig erstreckenden, transparenten Platte vorgegebener Dicke, wobei das Licht an einer ersten der beiden Plattenoberflächen in die Platte eintritt, an der zweiten Plattenoberfläche austritt und mindestens eine der beiden Oberflächen mit einer mikrostrukturierten Oberfläche versehen ist, die die Abstrahlungsrichtung des durchtretenden Lichtes derart beeinflusst, dass diese asymmetrisch bezogen auf die Oberflächennormale einer der beiden Plattenoberflächen erscheint. Dies wird dadurch erreicht, indem die verwendeten einzelnen Mikrooptiken vornehmlich Kegel, Pyramiden, Linsen oder Prismen, in ihrer Symmetrieachse bezogen auf die Oberflächennormale verkippt sind.The The invention relates to a device for the direction of the light of any Illuminant based on refraction with a surface extending, transparent plate of predetermined thickness, with the light on one first of the two plate surfaces enters the plate, exits at the second plate surface and at least one of the two surfaces having a microstructured one Surface provided is the direction of emission of the transmitted light in such a way influences that asymmetrically with respect to the surface normal of a the two plate surfaces appears. This is achieved by the individual used Micro-optics mainly cones, pyramids, lenses or prisms, are tilted in their symmetry axis with respect to the surface normal.

Derartige erfindungsgemäße, optisch wirksame Oberflächen werden verwendet, um den Öffnungswinkel von Leuchtmitteln, insbesondere von Leuchten zu beschränken. Dadurch wird häufig eine Entblendung gemäß einschlägiger Arbeitsvorschriften gewährleistet oder auch der Lichtaustritt in eine bevorzugte Abstrahlrichtung gelenkt. Sehr flache Leuchtenaufbauten werden möglich.such according to the invention, optically effective surfaces are used to the opening angle of bulbs, in particular of luminaires. Thereby becomes common glare control in accordance with relevant work regulations guaranteed or the light emission in a preferred direction of emission directed. Very flat lighting structures become possible.

Andrerseits sind verschiedene Einrichtungen zur Lichtrichtung, die auf der Basis von Reflexion beruhen bekannt. Dies sind meist makroskopische Oberflächen in Form von Spiegeln, die auftreffendes Licht in eine gewünschte Richtung lenken. Die Leuchten werden in diesem Fall im Aufbau sehr hoch, das austretende Licht scheint sehr hart.On the other hand are different facilities to the light direction, based on based on reflection. These are mostly macroscopic surfaces in Shape of mirrors, the incident light in a desired direction to steer. The lights in this case are very high in construction, the escaping light seems very hard.

Ebenso sind zur Entblendung und symmetrischer Abstrahlung auf Basis von Refraktion Mikroprismen, Kegel und Pyramiden bekannt. Diese eignen sich zu Entblendungszwecken, flache Leuchtenaufbauten und weiches Licht sind realisierbar. Allerdings ist asymmetrische Abstrahlung nicht möglich.As well are for glare and symmetrical radiation based on Refraction microprisms, cones and pyramids known. These are suitable for glare control purposes, flat lighting fixtures and soft light are feasible. However, asymmetric radiation is not possible.

Der Erfindung liegt somit die Aufgabe zugrunde, eine optische Oberfläche zur Richtung des Lichtes verschiedener Leuchtmittel auf Basis von Brechung oder Totalreflexion, oder einer Mischung beider Effekte, bereitzustellen und mit den positiven Eigenschaften der refraktiven optischen Elemente, niedrige Aufbauten und hohe Transmission, zu kombinieren.Of the Invention is therefore the object of an optical surface for Direction of the light of different bulbs based on refraction or total reflection, or a mixture of both effects and with the positive properties of the refractive optical elements, low Superstructures and high transmission, combine.

Erfindungsgemäß wird dieses durch eine flächig ausgedehnte Platte erreicht, die vornehmlich auf der dem Leuchtmittel abgewandten Seite mit Mikroprismen, Mikrokegeln oder Mikropyramiden versehen ist, wobei die Symmetrieachse der einzelnen Mikroelemente gegen die Oberflächennormale der Platte verkippt ist. Entsprechend der verwendeten Leuchtmittel und gewünschten Abstrahlcharakteristika können die Mikroelemente unterschiedlich verkippt werden.According to the invention this through a plane reached an extended plate, mainly on the bulb opposite side with microprisms, micro cones or micropyramids is provided, wherein the axis of symmetry of the individual microelements against the surface normal the plate is tilted. According to the used bulbs and desired Abstrahlcharakteristika can the microelements are tilted differently.

Die erfindungsgemäße Platte kann aus transparenten, thermoplastischen Kunststoffen wie Polycarbonat, PMMA oder PE im Heißprägeverfahren oder Spritzverfahren 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 sprayed.

In 1 ist eine mikrostrukturierte Prismenplatte (2) dargestellt, mit der die eintretenden Lichtstrahlen (1) über Lichtbrechung in der Mikrostruktur in den engeren Abstrahlwinkel der symmetrisch austretenden Lichtstrahlen (4) transformiert werden.In 1 is a microstructured prism plate ( 2 ), with which the incoming light beams ( 1 ) about refraction in the microstructure in the narrower beam angle of the symmetrically emerging light beams ( 4 ) are transformed.

Wie in 2 in einem Ausführungsbeispiel dargestellt, entstehen durch die Verkippung um den Kippwinkel (6) der einzelnen Mikroelemente in der Prismenplatte (3) asymmetrisch austretende Lichtstrahlen (5).As in 2 shown in one embodiment, caused by the tilt of the tilt angle ( 6 ) of the individual microelements in the prism plate ( 3 ) asymmetrically emerging light beams ( 5 ).

Die auf der Gegenseite abschließende Oberfläche der Platte kann optisch glatt oder ebenso strukturiert sein.The on the opposite side final surface the plate can be optically smooth or structured as well.
