Abstract

Light wall (10) is made of transparent pane of glass or plastic and contains LED lights to illuminate wall surface. It is positioned behind computer screen (12). Control unit is connected to computer output with signal corresponding to brightness of screen and is used to set light intensity of LEDs in light wall corresponding to intensity of computer screen.

Description

Die Erfindung betrifft eine Lichtwand mit Leuchtmitteln, einer die Helligkeit der Leuchtmittel steuernden Steuereinheit und einer von den Leuchtmitteln im wesentlichen gleichförmig beleuchteten Fläche.The invention relates to a light wall with illuminants, one that controls the brightness of the illuminants Control unit and a surface illuminated essentially uniformly by the illuminants.

Die meisten der Büroarbeitsplätze sind heute mit einem Bildschirm versehen. Das Arbeiten an einem solchen Bildschirm-Arbeitsplatz belastet die Augen.Most of the office workplaces today are with a screen Mistake. Working on such a screen workstation strains the eyes.

Einer dieser Gründe besteht darin, dass das Auge von Gegenlicht geblendet wird, einem Problem, dem man durch eine hinter dem Bildschirm angeordnete Blende entgegenwirken kann. Diese Blenden wirken aber nur gegen Gegenlicht. Es besteht aber weiter das Problem, dass das Auge, das den Bildschirm verlässt, sich an die Helligkeit seines Blickfelds adaptieren. Bei einem erheblichen Helligkeitsunterschied zwischen dem Bildschirm und der diesen umgebenden Fläche führt dies zu einer zusätzlichen Belastung der Augen.One of those reasons is that the eye is blinded by back light, a problem that is can counteract the aperture arranged behind the screen. This Apertures only work against back light. But it continues the problem that the eye that leaves the screen is up adapt to the brightness of his field of vision. With a significant Difference in brightness between the screen and the surrounding area does this to an additional burden of the eyes.

Der Erfindung liegt die Aufgabe zugrunde, eine Lichtwand der eingangs genannten Art zu schaffen zu schaffen, die hinter dem Bildschirm angeordnet zu einer geringeren Belastung der Augen an einem Bildschirm-Arbeitsplatz führt.The invention has for its object a To create light wall of the type mentioned in the introduction arranged behind the screen at a lower load of the Eyes in a screen workplace.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Lichtwand mit einer Steuereinheit mit einem Eingang versehen ist, der mit einem Ausgang des Computers, an dem ein der jeweiligen Helligkeit des Bildschirm entsprechendes Signal anliegt, verbunden ist, wobei die Steuereinheit die Helligkeit der Leuchtmittel der Lichtwand derart regelt, dass die Helligkeit der Lichtwand immer im wesentlichen der mittleren Helligkeit des Bildschirm entspricht, sich also der Helligkeit des Bildschirms anpasst.According to the invention, this object solved, that the light wall is provided with a control unit with an input is that with an output of the computer at which one of the respective brightness the corresponding signal is present, is connected, wherein the control unit the brightness of the illuminants of the light wall regulates such that the brightness of the light wall is always essentially corresponds to the average brightness of the screen, i.e. the Adjusts screen brightness.

Es wird also vorgeschlagen, ein der jeweiligen durchschnittlichen Helligkeit des Bildschirms entsprechendes Signal, das an einem Ausgang des Computers anliegt, an den Eingang einer Steuereinheit für die Lichtwand zu führen, wobei die Steuereinheit dieses Signal aufnimmt und die Helligkeit der Lichtwand entsprechend der Gesamthelligkeit des Bildschirms regelt, wobei diese Regelung zeitlich gedämpft erfolgt, kurzzeitige Helligkeitssprünge des Bildschirms also nur zeitlich verzögert und gedämpft nachvollzogen werden. Es versteht sich, dass sowohl die Grundhelligkeit der Lichtwand als auch der Kontrast (die Helligkeitsdifferenz) zwischen Lichtwand und Bildschirm manuell einstellbar sein sollten.So it is suggested one of the corresponding to the respective average brightness of the screen Signal that is present at an output of the computer to the input a control unit for to guide the light wall the control unit receives this signal and the brightness the light wall according to the overall brightness of the screen regulates, whereby this regulation takes place in a temporally dampened manner, brief brightness jumps of the screen so only delayed and understand subdued become. It is understood that both the basic brightness of the light wall as well as the contrast (the difference in brightness) between the light wall and Screen should be manually adjustable.

Bei den Leuchtmitteln sollte es sich um LED handeln, der aus einer transparenten Scheibe aus Glas oder Kunststoff bestehenden Wand angebracht sind und die dem Betrachter zugewandte Fläche der Wand beleuchten. Die Lichtwand kann als Acrylglasplatte ausgebildet sein, die an den Flächen, an denen das Licht austreten soll, durch Aufbringen eines Rasters (etwa durch Siebdruck, einer Gravur oder dergleichen) versehen ist.The bulbs should be are LED, which consist of a transparent pane of glass or Plastic existing wall are attached and the viewer facing surface illuminate the wall. The light wall can be designed as an acrylic glass plate be on the surfaces where the light is supposed to come out by applying a grid (such as by screen printing, engraving or the like).

Bei einer besonders bevorzugten Ausführungsform ist die Licht mit roten, gelben und blauen LED versehen, die Steuereinheit ist zur getrennten Ansteuerung dieser Gruppen von LED entsprechend den jeweiligen Farbhelligkeiten des Bildschirms eingerichtet. Auf diese Weise ist es möglich, auch innerhalb der einzelnen Farbkomponenten für einen möglichst geringen Kontrast zwischen Bildschirm und Lichtwand zu sorgen.In a particularly preferred embodiment the light is provided with red, yellow and blue LEDs, the control unit is for the separate control of these groups of LEDs according to the respective color brightness of the screen set up. To this Way it is possible also within the individual color components for the lowest possible contrast between To worry screen and light wall.

Die Erfindung ist in der beiliegenden Zeichnung schematisch erläutert.The invention is in the accompanying Drawing explained schematically.

Der dargestellte Arbeitsplatz ist mit einem Bildschirm 12 versehen. Hinter diesem Bildschirm 10 ist eine Lichtwand 10 angeordnet. Eine – nicht gezeigte – Steuereinheit ist mit einem Ausgang des – nicht gezeigten – Computers verbunden. Die Steuereinheit steuert die Helligkeit der Lichtwand entsprechend der Helligkeit des Bildschirms, wie oben angegeben.The workplace shown is with a screen 12 Mistake. Behind this screen 10 is a wall of light 10 arranged. A control unit (not shown) is connected to an output of the computer (not shown). The control unit controls the brightness of the light wall according to the brightness of the screen as stated above.

Anders als dargestellt kann der Bildschirm auch in die Lichtwand integriert sein, die Lichtwand kann als von dem Bildschirm abklappbare Flügel ausgebildet sein.The screen can do differently than shown be integrated into the light wall, the light wall can be as of that Fold-down screen be trained.
