Description
Lichtverteiler. Gegenstand des Hauptpatentes bildet ein lichtbrechender, als Lichtverteiler wirkender Körper von der allgemeinen Gestalt eines einfachen Meniskus, bei dem der Randteil in einen lichtstrahlensammelnden Meniskus übergeht und dessen Kennzeichen darin besteht, daß der Körper in seinem Mittelteil eine Zerstreuungslinie ist, zum Zwecke der Erzielung einer gleichmäßigen Beleuchtung auf einer zur optischen Achse senkrechten Ebene.Light distributor. The subject of the main patent is a refractive, body acting as a light diffuser of the general shape of a simple one Meniscus in which the edge part merges into a light beam collecting meniscus and its distinguishing feature is that the body has a line of dispersion in its central part is, for the purpose of achieving uniform illumination on an optical Axis vertical plane.
Gegenstand des Zusatzpatentes bildet eine Verbesserung des Lichtverteilers des Hauptpatentes durch Anordnung eines Hohlspiegels am 'Meniskuskörper in der Weise, daß sämtliche von der Lichtquelle ausgehenden Strahlen durch den Meniskus gesandt werden, so daß theoretisch die doppelte Lichtstärke erzielt wird.The subject of the additional patent is an improvement of the light distributor of the main patent by arranging a concave mirror on the 'meniscus body in such a way that that all rays emanating from the light source are sent through the meniscus so that theoretically twice the light intensity is achieved.
Der Hohlspiegel und der Meniskus umgeben die Lichtquelle in der Weise, daß sich ihre beiden Öffnungswinkel zu einem Vollkreise ergänzen. Der Öffnungswinkel des Hohlspiegels kann dabei gleich oder kleiner als i8o° sein.The concave mirror and the meniscus surround the light source in such a way that that their two opening angles complement each other to form a full circle. The opening angle of the concave mirror can be equal to or smaller than 180 °.
Wie aus Fig. i der Zeichnung hervorgeht, fällt, wenn der Hohlspiegel um die Lichtquelle als Mittelpunkt kugelförmig gekrümmt wird, das Bild der Lichtquelle mit dieser selbst zusammen und alle Lichtstrahlen gehen durch sie hindurch. Bei anderer Formgebung des Hohlspiegels kann das Bild der Lichtquelle ober-, unterhalb öder seitlich von dieser verlegt werden, womit jede andere Lichtverteilung erzielbar ist.As can be seen from Fig. I of the drawing, falls when the concave mirror is spherically curved around the light source as the center, the image of the light source together with this itself and all rays of light pass through it. at Another shape of the concave mirror can show the image of the light source above, below or to the side of this, with which any other light distribution can be achieved is.
Die Fig. 2 bis 4 zeigen in ähnlicher Weise wie beim Hauptpatent Ausführungsformen, bei denen das entbehrliche Material entfernt ist. Bei den Fig. 5 und 6 sind statt der kugelförmigen Begrenzungsflächen der Materialausnehmungen ebene Flächen vorgesehen.Figs. 2 to 4 show in a manner similar to the main patent embodiments, in which the dispensable material has been removed. In Figs. 5 and 6 are held the spherical boundary surfaces of the material recesses provided flat surfaces.
