1. Allgemeine B eschreibung1. General description

Die Erfindung betrifft ein computergesteuertes System zur Projektion von Bildern an eine Raumdecke.The invention relates to a computer-controlled system for projecting images onto a room ceiling.

2. Die Erfindung setzt sich aus verschiedenen bereits bekannten technischen Bestandteilen zusammen, die jedoch in ihrer Zusammenfuhrung eine völlig neue, bisher nicht bekannte Erfindung darstellen. Zwar ist die Projektion von Bildern seit langem bekannt, in der hier verwandten Technik mit der zentralen Steuerung über eine nahezu beliebige Anzahl von Bildern an Decken ist dies jedoch bisher nicht bekannt. Die Erfindung zeichnet sich insbesondere dadurch aus, daß sie es ermöglicht, gleiche Bilder an einer Vielzahl von Plätzen in hoher Qualität zu projizieren.2. The invention is made up of various already known technical components which, when combined, however, represent a completely new, previously unknown invention. Although the projection of images has been known for a long time, this has not been known in the technology used here with central control of almost any number of images on ceilings. The invention is particularly distinguished by the fact that it makes it possible to project the same images in high quality in a large number of places.

3. Die Erfindung setzt sich zusammen aus einem PC mit einem höheren Speichermedium, einem Glasfiberkabelsystem sowie lokalen Projektoren. Die Erfindung kann um ein Audiogerät erweitert werden, das getrennt oder abgestimmt auf die Bildübermittlung akustische Signale, Sprache, Musik überträgt.3. The invention consists of a PC with a higher storage medium, a fiber optic cable system and local projectors. The invention can be expanded to include an audio device that transmits acoustic signals, speech and music separately or in conjunction with the image transmission.

4. Ein Computer als zentrale Steuereinheit mit hohem Speichermedium (1) transponiert die zu projizierenden Bilder im Diaformat auf digitale Impulse. Diese Impulse werden über Netzwerkkabel (2) zu den jeweiligen Punkten transportiert, an denen eine Projektion erfolgen soll. Der einzelne Projektor (3) ist kompakt und kann frei stehen oder beispielsweise an Bettrahmen befestigt werden.4. A computer as a central control unit with a large storage medium (1) transposes the images to be projected in slide format to digital impulses. These impulses are transported via network cables (2) to the respective points where a projection is to take place. The individual projector (3) is compact and can stand freely or be attached to a bed frame, for example.

Der Projektor kann mit einer kleinen Steuereinheit die digitalen Impulse in Bilder umwandeln und so an die Decke projizieren (5).With the help of a small control unit, the projector can convert the digital impulses into images and project them onto the ceiling (5).

Die Erfindung kann ergänzt werden durch ein Audi-Bauteil (PC-Karte) im Projektor (3), so daß über einen Kopfhörer (4) auch akustische Signale übermittelt werden können. The invention can be supplemented by an audio component (PC card) in the projector (3), so that acoustic signals can also be transmitted via headphones (4).

Die Netzwerkverkabelung erlaubt die Ansteuerung beliebig vieler Punkte ohne Qualitätsverlust der übertragenen Daten.The network cabling allows the control of any number of points without any loss of quality of the transmitted data.

Claims (2)

1. Deckenlichtprojektionssystem, bestehend aus einem PC mit hohem Speichermedium, angeschlossen an eine Netzwerkverkabelung und einen Deckenlichtprojektor mit kleinem Computer, bei dem über die zentrale Steuereinheit Dias digitalisiert werden, über die Verkabelung dem einzelnen Projektor zugeleitet werden, der das Bild zurückvisualiert und an die Decke projiziert. 1. Ceiling light projection system, consisting of a PC with a high storage medium, connected to a network cabling and a ceiling light projector with a small computer, in which slides are digitized via the central control unit and fed via the cabling to the individual projector, which visualizes the image back and projects it onto the ceiling. 2. Anspruch gemäß 1. ergänzt um eine Audio-Karte im Projektor, die mittels Ohrkopfhörer auch akustische Signale, Worte, Musik übertragen kann. 2. Claim according to 1. supplemented by an audio card in the projector, which can also transmit acoustic signals, words, music via earphones.
