Description

Künstliche Sternenhimmel an Decken oder Wänden werden nach herkömmlicher Technik mittels Leuchtdioden (LED) und Fiberadern und Fibergeneratoren erzeugt. Nach einen anderen Ansatz auch mittels Leuchtdioden (LED) und einem Stanzset, bei der die Nachthimmelkuppel schlicht über eine Lampe gelegt wird. Dabei ist der erzeugt Sternenhimmel stets statisch.artificial Starry sky on ceilings or walls become after conventional Technology using light emitting diodes (LED) and fiber adapters and fiber generators generated. After another approach also by means of light emitting diodes (LED) and a punching set, in which the night sky dome simply over a Lamp is placed. The generated starry sky is always static.

Der im Schutzanspruch angegebenen Erfindung liegt der Gedanke zugrunde mittels eines Laserprojektors das veränderliche und dynamische Abbild eines Sternenhimmels zu projizieren.Of the in protection claim specified invention is based on the idea using a laser projector, the variable and dynamic image to project a starry sky.

Bei dem Aufbau des Sternenlaserprojektors wird ein Laser 2 mit der Wellenlänge von 532 nm Grün verwendet, oder eine ander Frabe Rot (650mn), Blau (440 bis 473), Orange (594nm), Violet (405nm), Gelb, Weiss. Die Verwendung eines Lasers 2 kann mit seiner schmalen spektralen Bandbreite begründet werden. Diese ermöglicht bei der spektralen Zerlegung eine Erzeugung von einzelnen Punkten. Um ein Sternenbild zu erzeugen wird der Laserstrahl geteilt. Dies wird erreicht mit Hilfe einer Spektralfolie oder einer Diffraktiven (DOEs) 1. Die Folie ist wie ein Gitter aufgebaut und erzeugt physikalische Effekte der Beugung und Interferenz. Die Spektralgitter (3) werden im Versatz in verschiedene Winkel übereinander gelegt und somit der Lichtstrahl zerlegtThe construction of the star laser projector becomes a laser 2 used with the wavelength of 532 nm green, or another red (650mn), blue (440 to 473), orange (594nm), violet (405nm), yellow, white. The use of a laser 2 can be justified with its narrow spectral bandwidth. This enables the generation of single points in the spectral decomposition. To create a constellation, the laser beam is split. This is achieved by means of a spectral film or a diffractive (DOEs) 1 , The film is constructed like a grid and creates physical effects of diffraction and interference. The spectral grating ( 3 ) are placed in the offset in different angles on top of each other and thus the light beam decomposed

Auf der Spektralfolie ist ein dünnes Gitter, das die von der Lichtquelle kommenden Lichtstrahlen in waagerechter, senkrechter und diagonaler Richtung beugt. Die verschiedenen Spektralanteile werden dabei unterschiedlich stark gebeugt. Beim Blick durch das Spektral liegen die blauen Enden des Spektrums der Lichtquelle am nächsten, die roten am weitesten von ihr entfernt. Die Spektralfolie zerlegt das Licht in seine Farbanteile.On the spectral film is a thin one Grid, which illuminates the light rays coming from the light source horizontally, vertical and diagonal direction bends. The different spectral components are diffracted differently. When looking through the Spectral the blue ends of the spectrum of the light source lie on next the red furthest away from her. The spectral film breaks this up Light in its color components.

Durch die mehrfache Verwendung und Positionierung der Folien kann die Anzahl der erzeugten Punkte verdoppelt werden. Daher ist die Anzahl der Punkte von der Anzahl der aufeinander liegenden Folien abhängig. Die Position der Punkte ist von der Drehung der einzelnen Folien abhängig. Auf diese Weise lassen sich beliebig viele Variationen des Sternenhimmels projizieren.By the multiple use and positioning of the slides can the Number of generated points to be doubled. Therefore, the number is depending on the number of superimposed slides. The Position of the dots depends on the rotation of the individual slides. On this way you can choose any number of variations of the starry sky project.

Mit der Erfindung ist es möglich den Nachthimmel mit einer bisher nicht erreichten Authentizität und Wirkungskraft abzubilden. Dabei ist das System außerordentlich flexibel und lässt sich an jede beliebige Projektionsfläche anpassen.With The invention is possible the night sky with a previously unattained authenticity and effectiveness map. The system is extremely flexible and let yourself to any projection surface to adjust.

Der Aufbau des Sternenlaserprojektors wird durch nachfolgende Skizzen belegt.Of the Construction of the star laser projector is through subsequent sketches busy.
