Description
Für die Bühnenprojektion sind sehr starke Lichtquellen erforderlich. Es kann aber naturgemäß nur ein Teil des Gesamtlichtstromes für die Durchleuchtung des Projektionsbildes verwendet werden.Very strong light sources are required for stage projection. But it can naturally only part of the total luminous flux for the illumination of the projection image be used.
Ausgehend von dem Umstand, daß der Projektionsapparat seinen Platz vorteilhaft in entsprechender Höhe vor dem zu projizierenden Prospekt, also bühnertseitig über der Proszeniumsöffnung, findet, beruht die Erfindung darauf, den für die Projektion nicht verwendbaren Teil des Lichtstromes als Scheihwerferlicht zur Beleuchtung der Spielfläche zu verwenden.Based on the fact that the projection apparatus is advantageous in its place in the corresponding amount in front of the prospectus to be projected, i.e. over on the stage side the proscenium opening, thinks, the invention is based on it, that for the projection is not usable part of the luminous flux as a spotlight to illuminate the playing area to use.

Abb. 2 zeigt einen Schnitt durch das Gehäuse eines Projektionsapparates gemäß der Erfindung, Abb. 3 eine besonders für diesen Zweck aus-»5 In the drawing, Fig. 1 shows the overall arrangement shown schematically. Fig. 2 shows a section through the housing of a projection apparatus according to the invention, Fig. 3 a specially designed for this purpose

In entsprechender Höhe, über der Proszeniumsöffnung ι ist auf dem Beleuchtungsgang 2 der Projektionsapparat 3 aufgestellt, der das zu projizierende Bild auf die Prospektlein-At a corresponding height, above the proscenium opening ι is on the lighting corridor 2 the projection apparatus 3 is set up, which puts the image to be projected onto the prospectus
»5 wand 4 wirft, während eine besondere Spiegeleinrichtung den zur Projektion nicht ausnutzbaren Teil des Lichtstromes als Schejnwerferbündel 5 auf die Spielfläche 6 wirft. Zu diesem Zwecke ist ΐηΐ Boden des Lampengehäuses 3 (Abb. 2) eine Lichtöffnung 7 vorgesehen, durch die der über der Lichtquelle 8 angebrachte Scheinwerferspiegel 9 den Teil des Lichtstromes, der durch den Spiegel 10 und den Kondensator 11 nicht dem Projektionsbild 12 zugeführt wird, nach unten wirft.»5 wall 4 throws while a special mirror setup the part of the luminous flux that cannot be used for projection as a headlamp beam 5 throws onto the playing surface 6. For this purpose, ΐηΐ is the bottom of the lamp housing 3 (Fig. 2) a light opening 7 is provided, through which the headlight mirror 9 mounted above the light source 8 the part of the luminous flux passing through the mirror 10 and the condenser 11 not the projected image 12 is fed, throws down.
Abb. 3 zeigt eine besondere Ausgestaltung einer hochwattigen Projektionsglühlampe, bei der die Spiegel 9 und 10 durch entsprechende Versilberung des Lampenkörpers selbst ausgebildet sind.Fig. 3 shows a special embodiment of a high-wattage projection lamp, at the mirrors 9 and 10 formed by appropriate silver plating of the lamp body itself are.
Die Erfindung kann natürlich in analoger Weise auch bei mit Bogenlampen betriebenen Projektionseinrichtungen ausgebildet werden.The invention can of course also be used in an analogous manner in the case of arc lamps operated Projection devices are formed.
