Abstract

The plate has micro-structures formed as quadratic micro-pyramids, circular cones and linear prisms. The micro-pyramids i.e. pitched roof, are embedded in the plate with pyramid angles in a preset angle range between 100 to 200 degrees, and where the plate is made of transparent plastic. The pyramids are connected with the crossed linear prisms on the plate.

Description

Stand der Technik:State of the art:

Entblenden im Lampen- und Leuchtenbereich heißt im Allgemeinen, durch technische Maßnahmen bei Leuchten einen Lichtöffnungswinkel von höchstens 60° bereit zu stellen, was einem Entblendungswinkel von 30° entspricht. Entblendung erfolgt derzeit hauptsächlich über Lamellen, die als lineare oder parabolische Reflektoren senkrecht zu länglichen Leuchtmitteln oder in quadratischer Anordnung bei gebogenen oder flächigen Leuchtmitteln ausgebildet werden. Die Folge sind Effizienzverluste durch einerseits Reflexionsverluste und durch die teilweise Abschattung des Leuchtmittels durch die Horizontalausdehnung der Lamellen.. Weiterhin werden größere Bauhöhen in Kauf genommen.Entblenden in the field of lamps and lights is generally called by technical activities when lighting a light opening angle from at most 60 ° ready which corresponds to a glare angle of 30 °. Glare reduction is currently taking place mainly via fins, as linear or parabolic reflectors perpendicular to elongated Bulbs or in a square arrangement with curved or flat Illuminants are formed. The result is efficiency losses by on the one hand reflection losses and by the partial shading of the illuminant by the horizontal extent of the slats .. Furthermore, larger heights in purchase taken.

Transparente Abdeckungen aus Kunststoff oder Glas kommen im Lampen und Leuchtenbereich häufig als extrudierte, gespritzte, tiefgezogene oder gegossene Lichtwannen zum Einsatz. Diese dienen dann als Diffusoren zu den darunter liegenden Leuchtmitteln. Eine Entblendung findet nur durch Einsatz entsprechender Aperturblenden bei größeren Bauhöhen der Leuchten statt. Der Lichttransmissionsgrad und somit die Effektivität der Leuchte ist dadurch stark gemindert.transparent Covers made of plastic or glass are often used in the lamps and lighting sector extruded, sprayed, deep-drawn or cast light wells for use. These then serve as diffusers to the underlying bulbs. A glare only occurs through the use of appropriate aperture for larger heights of Lights instead. The light transmittance and thus the effectiveness of the lamp is greatly reduced.

Neuerdings sind für das Ziel der Leuchtenentblendung bei hoher Effizienz auch Mikroprismenplatten aus transparentem Kunststoff im Einsatz, wobei die zur Anwendung kommenden Mikrostrukturen entweder

  • 1. Als Quadratische Pyramiden
  • 2. Als Zirkulare Kegel
  • 3. Als Lineare Prismen
Recently, for the goal of the glare suppression with high efficiency and micro prism plates made of transparent plastic in use, wherein the microstructures used either
  • 1. As Square Pyramids
  • 2. As circular cone
  • 3. As linear prisms

Mit Spitzenwinkeln zwischen 100 bis 120 Grad ausgebildet sind.With Point angles between 100 to 120 degrees are formed.

Neuerunginnovation

Die hier vorgestellte neue Struktur nach 1 basiert auch auf Mikropyramiden, die in die Struktur eingeprägt sind mit Pyramidenwinkeln im vorab beschriebenen Winkelbereich, ist jedoch neu in Ihrer Erscheinungsform, indem die im rechteckigen (Sonderfall quadratisch) Muster eingeprägten Pyramiden im Verbund sich kreuzende lineare Prismen auf der Prismenplatte ergeben.The new structure presented here 1 is also based on micropyramids imprinted into the structure with pyramid angles in the angular range described above, but is new in appearance because the pyramids embossed in the rectangular (special case square) pattern in combination result in intersecting linear prisms on the prism plate.

Diese Oberflächenstruktur einer Mikroprismenplatte wirkt wie auf der Platte erhabene Mikropyramiden ebenso entblendend, ist werkzeugtechnisch jedoch einfacher, da spanabhebend, herstellbar.These surface structure a microprism plate acts as raised on the plate micro-pyramids just as glare-reducing, however, it is simpler in terms of tools, as cutting, produced.
