Description

Bildwerfer für auf- und durchfallendes Licht Zusatz zum Patent 469 668 Gegenstand des Hauptpatents, ist ein Bildwerfer für auf- und durchfallendes. Licht, dessen Glühlampe den Stellungswechsel von der einen Projektionsart zur anderen durch eine Drehung um eine Achse erfährt, welche mit der MTinkelhalbierenden der beiden Normalstellungen der Lampenleuchtfläche zusammenfällt.Projector for incident and transmitted light Addition to patent 469 668 The subject of the main patent is an image projector for conspicuous and diaphanous items. Light whose incandescent lamp changes position from one type of projection to the other through a rotation around an axis, which corresponds to the M bisector of the both normal positions of the lamp surface coincides.

Der Gegenstand der- vorliegenden Zusatzerfindung bezweckt, die in der Zeichnung angegebene Dreh- und Schwenkachse 5 der Lichtquelle i bzw. ia zu dieser so anzuordnen, daß der Glaskörper und damit auch die Leuchtfläche q. bzw. qa näher an die Kondensorlinsen 7 bzw. io herarigebracht werden können, als -dies beim Gegenstand das Hauptpatents mit Rücksicht auf den Platz, den der Reflektor 2 bzw. 2a beim Drehen benötige, möglich ist. Erfindungsgemäß, soll die Leuchtfläche der Lichtquelle außerhalb ihrer Drehachse 5 liegen, so daß sie beim Drehen der Lichtquelle aus einer Arbeitsstellung in die andere eine Kreisbewegung ausführt. PATENTANSPRUCH:The object of the present additional invention aims to arrange the indicated in the drawing rotation and pivot axis 5 of the light source i or ia to this so that the glass body and thus also the luminous surface q. or qa can be brought closer to the condenser lenses 7 or io than - this is possible with the subject matter of the main patent with regard to the space that the reflector 2 or 2a requires when rotating. According to the invention, the luminous surface of the light source should lie outside its axis of rotation 5, so that it executes a circular movement when the light source is rotated from one working position to the other.
