Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung zur Erzeugung von Lichtsignalen, insbesondere eine Verkehrsampel. Die erfindungsgemäße Vorrrichtung enthält ein Gehäuse mit mindestens einer Öffnung, die durch eine Platte geschlossen wird, deren Absorption elektrisch gesteuert werden kann, wobei sich im Inneren des Gehäuses hinter der Öffnung ein Diffusorelement befindet, das durch die Platte einfallendes Licht reflektiert. Bevorzugte Schaltzustände der Platte sind entweder schwarz (Absorption über den gesamten spektralen Bereich des sichtbaren Lichtes) und farbig transparent (geringe Absorption in bestimmten spektralen Bereichen) oder transparent (keine Absorption über den gesamten spektralen Bereich des sichtbaren Lichtes). Mit der erfindungsgemäßen Vorrichtung werden die Lichtsignale dadurch erzeugt, dass das Umgebungslicht auf die Platte trifft und je nach Schaltzustand ganz, teilweise oder gar nicht von der Platte absorbiert wird. Der durch die Platte transmittierte Lichtanteil wird durch die hinter der Platte befindliche Diffusorplatte reflektiert und ein zweites Mal durch die Platte transmittiert und kann dann von aussen wahrgenommen werden.The present invention relates to a device for generating light signals, in particular a traffic light. The device according to the invention contains a housing having at least one opening which is closed by a plate, whose absorption can be electrically controlled, being in the interior of the Housing behind the opening is a diffuser element located through the plate incident light reflects. Preferred switching states of the disk are either black (absorption over the entire spectral range of visible light) and colored transparent (low absorption in certain spectral ranges) or transparent (no absorption over the entire spectral range of the visible Light). With the device according to the invention, the light signals are characterized generates ambient light on the plate and, depending on the switching state, partially or not absorbed by the plate. The one through the plate transmitted light component is through the plate located behind the diffuser plate reflected and transmitted a second time through the plate and can then from be perceived outside.
