Abstract

The invention relates to a device in which one or more mirrors are integrated in the beam path to enlarge the distance between the projector part and the screen.

Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Ober­ begriff des Anspruchs 1.The invention relates to a device according to the waiter Concept of claim 1.

Das in meiner Patentanmeldung PCT/DE 99/00885 beschriebene Rück­ projektionsgerät, welches mittels anamorphotischer Bildzusammen­ fassung eine sehr geringe Gehäusebautiefe besitzt, zeichnet sich dadurch aus, daß das Projektorenlichtbündel über max. einen Spiegel mehr oder weniger direkt auf den Hauptspiegel fällt, der es auf die Bildfläche lenkt.The back described in my patent application PCT / DE 99/00885 projection device, which together by means of anamorphic image version has a very low housing depth characterized in that the projector light beam over max. one Mirror falls more or less directly on the main mirror that it directs the picture.

Eine bessere Handhabung für Größen wie Bildschärfe u. Verzerrungen erreicht man aber dadurch, daß der Abstand zwischen Projektoren­ teil und Bildfläche möglichst groß gestaltet wird. Better handling for sizes such as sharpness and. Distortions but is achieved in that the distance between projectors part and image area is designed as large as possible.  

Der Quer-Projektor mit vielfacher Lichtumlenkung kommt dieser Forderung entgegen. In ihm trifft das Projektorenlichtbündel entweder direkt oder gegebenenfalls auch schon durch mehrfache Spiegelung auf ein Spiegelpaar(bevorzugt sich am Rand des Ge­ häuses befindend), in welchem sich die Spiegel in etwa im rechten Winkel gegenüberstehen und somit das Licht einerseits zurück­ werfen, dies aber auf einer anderen Ebene geschied - Winkelspiegel- . Hiermit wird das zur Verfügung stehende Volumen voll ausgenutzt und die Wegstrecke des Lichts max. verlängert.The cross projector with multiple light deflection comes this Counter claim. The projector beam of light hits it either directly or, if necessary, by multiple Reflection on a pair of mirrors (preferred at the edge of the Ge house), in which the mirror is roughly on the right Angle face and thus the light back on the one hand throw this but divorced on another level - angle mirror. This fully utilizes the available volume and the path of the light max. extended.

Auch erlaubt diese Bauform - etwa an einem Breitbildgerät - den Hauptspiegel an der langen Ober, - od. Unterseite des Bildes vorzu­ sehen, was bei der dann nur noch rel. geringen Distanz der vertika­ len Bildhöhe geringere Anforderungen etwa an die Tiefenschärfe od. gleichmäßige Bildausleuchtung stellt.This design also allows - for example on a widescreen device Primary mirror on the long upper or lower side of the picture see what is then only rel. short distance of the vertika len image height, less requirements such as depth of field or provides even image illumination.

Es besteht hier die Möglichkeit den Hauptspiegel nur in einer teilzylinderartigen Form auszuführen, was im Gegensatz zu einer Parabolform wahrscheinlich wesentlich kostengünstiger ist.There is only one option here for the primary mirror to execute part-cylindrical shape, which is in contrast to a Parabolic shape is probably much cheaper.

Claims (2)

1. Quer-Projektor mit vielfacher Lichtumlenkung, dadurch gekenn­ zeichnet, daß er ein Spiegelpaar aufweist, dessen Spiegel sich in etwa im rechten Winkel gegenüberstehen - Winkelspiegel -, welches das Projektorenlichtbündel, bezogen auf die Gehäuse­ tiefe, auf einer anderen Ebene auf den Hauptspiegel gibt und somit das Gehäusevolumen max. genutzt wird.1. Cross-projector with multiple light deflection, characterized in that it has a pair of mirrors, the mirrors of which face each other at approximately a right angle - angled mirror - which gives the projector light beam, based on the housing depth, on another level on the main mirror and thus the housing volume max. is being used. 2. Quer-Projektor bei dem z. B. durch vielfache Lichtumlenkung die Voraussetzung geschaffen ist, den ansonsten parabolartigen Hauptspiegel durch einen mit einer zylinderausschnittartigen Form zu ersetzen.2. Cross-projector in the z. B. by multiple light deflection the prerequisite is created, the otherwise parabolic Main mirror by one with a cylindrical cut-out To replace form.
