PATENTANSPRUCH:PATENT CLAIM: Beleuchtungseinrichtung, insbesondere für Projektionszwecke, bei der zwischen die Lichtquelle und das Bildfenster aus einer Vielzahl von Elementarlinsen gebildete Linsenraster geschaltet werden, dadurch gekennzeichnet, daß im Strahlengang eine einzige Rasterplatte (5) angebracht ist, deren Einzellinsen eine entsprechende Anzahl im Verhältnis zu den Abmessungen der einzelnen Rasterlinsen kleine Lichtquellenbilder in einer Ebene erzeugen, und die Rasterplatte so zur Lichtquelle, dem Kondensor oder Spiegel und dem Bildfenster angeordnet ist, daß die nach Art einer Lochkamera von den Lichtquellenbildern erzeugten Abbildungen der Einzellinsen des Rasters sich auf dem Bildfenster überdecken.Lighting device, in particular for projection purposes, in which between the light source and the picture window formed from a plurality of elementary lenses are connected, characterized in that a single grid plate (5) is attached in the beam path, the individual lenses of a corresponding number in relation to the dimensions of the individual lenticular lenses produce small light source images in a plane, and the raster plate is arranged in relation to the light source, the condenser or mirror and the image window that the images of the individual lenses of the raster created by the light source images in the manner of a pinhole camera overlap on the image window.
