Description
Mischfrequenz-Vorrichtung zur Erzielung flimmerfreier Beleuchtung beim Anschluß an Netze mit niedriger Grundfrequenz Das Hauptpatent bezieht sich auf eine Mischfrequenz-Vorrichtung, welche beim Anschlüß an 16'/,periodische Netze flimmerfreies Glühlampenlicht ergibt. Erfindungsgemäß ist die Anwendung dieser Vorrichtung nicht auf Netze mit i6213.Hz beschränkt, sondern bei allen Frequenzen möglich, bei denen normalerweise ein,Flimmern der Glühlampen auftritt. Die Vorrichtung kann also bei sinngemäßer Bemessung der Kondensatoren auch an Netze angeschlossen werden, deren Grundfrequenz tiefer, z. B. 15 Hz, oder höher, z. B. 25 Hz, als i62/3 Hz ist.Mixed frequency device for achieving flicker-free lighting when connected to networks with a low fundamental frequency. The main patent relates to a mixed frequency device which, when connected to 16 '/ periodic networks, produces flicker-free incandescent lamp light. According to the invention, the use of this device is not limited to networks with i6213.Hz, but possible at all frequencies at which flickering of the incandescent lamps normally occurs. The device can therefore also be connected to networks with a corresponding dimensioning of the capacitors, the base frequency of which is lower, e.g. B. 15 Hz, or higher, e.g. B. 25 Hz when i62 / 3 Hz.
