Description

Beleuchtungseinrichtung für Laufbild-bzw. Stehbildwerfer Zusatz zur Patentanmeldung Z 7045 IX a / 42 h (Auslegeschrift 1132 743) Die Erfindung betrifft eine weitere Ausgestaltung der Beleuchtungseinrichtung für Laufbild- bzw. Stehbildwerfer nach Patentanmeldung Z 7045 IX a/42 h.Lighting device for motion picture or. Still image projector Addition to patent application Z 7045 IX a / 42 h (Auslegeschrift 1132 743) The invention relates to a further embodiment of the lighting device for moving image or still image projector according to patent application Z 7045 IX a / 42 h.

Gemäß der Erfindung wird vorgeschlagen, den Kaltlichtspiegel im etwa telezentrischen Strahlengang zwischen zwei Linsen eines aus mehreren Linsen bestehenden Kondensors anzuordnen, gleichgültig, welche Gestaltung und Anordnung diese Köndensorlinsen erfahren.According to the invention it is proposed that the cold light mirror approximately telecentric beam path between two lenses consisting of several lenses To arrange condenser, regardless of the design and arrangement of these condenser lenses Experienced.

Die Wirksamkeit von Interferenzschichten, wie sie zur Herstellung wärmedurchlässiger Spiegel verwendet werden, läßt sich jeweils nur für einen einzigen Einfallswinkel optimal dimensionieren. Infolgedessen wird ein Spiegel, der durch ein stark konvergentes bzw. divergentes Strahlenbüschel beaufschlagt wird, niemals die bestmögliche Wirksamkeit ergeben. Dem wird durch die Anordnung des Umlenkspiegels im mindestens etwa parallelen Strahlenbüschel zwischen zwei Kondensorlinsen abgeholfen.The effectiveness of interference layers as used to manufacture heat-permeable mirror are used, can only be used for a single Dimension the angle of incidence optimally. As a result, a mirror that goes through a strongly convergent or divergent bundle of rays is acted upon, never result in the best possible effectiveness. This is due to the arrangement of the deflecting mirror remedied in the at least approximately parallel bundle of rays between two condenser lenses.

Die Erfindung wird an Hand eines Ausführungsbeispiels in der Zeichnung erläutert, bei dem der Spiegelkondensor ein Zwischenbild erzeugt. Die von der Lichtquelle 1 ausgehenden Strahlen werden durch den elliptischen Spiegel t auf der Kolbenwand der Glühlampe am Ort 3 der Entstehung des Zwischenbildes vereinigt. Zwischen den Kondensorlinsen 4 und 5, in welchem Zwischenraum das Beleuchtungsbündel mindestens annähernd parallel verläuft, wird der wärmedurchlässige Umlenkspiegel6 angeordnet. 7 ist das Bildfenster des Projektors.The invention is illustrated using an exemplary embodiment in the drawing explained, in which the mirror condenser generates an intermediate image. The one from the light source 1 outgoing rays are through the elliptical mirror t on the bulb wall the incandescent lamp combined at place 3 where the intermediate image was created. Between Condenser lenses 4 and 5, in which space the illumination beam at least runs approximately parallel, the heat-permeable deflecting mirror 6 is arranged. 7 is the projector's image window.
