The connection of the vertical rows takes place step by step one after the other by a mechanical switching device.

Der Erfindungsgedanke besteht nun darin, die namentlich bei größeren Schaltleistungen und kurzen Schaltzeiten auftretenden Schwierigkeiten der mechanischen Schalteinrichtung zu vermeiden, und zwar dadurch, daß die Anschaltung der einzelnen- Reihen durch Stromtore geschieht, welche ihrerseits durch Photoelemente oder Photozellen gesteuert werden. Diese wiederum werden über eine optische Einrichtung im entsprechenden Augenblick belichtet. Die Anschaltung der Reihen beginnt also mit der Belichtung ihrer Photozelle, während der Abschaltzeitpunkt am Stromtor oder Relais beliebig einstellbar ist. Die Einschaltedauer ist also ebenfalls einstellbar.The idea of the invention now consists in that, especially in the case of larger ones Switching capacities and short switching times occurring difficulties of the mechanical To avoid switching device, namely that the connection of the individual Rows through power gates happens, which in turn through photo elements or photocells being controlled. These are in turn via an optical device in the corresponding Moment exposed. The connection of the rows begins with the exposure your photocell, during the switch-off time at the power gate or relay is adjustable. The switch-on time can also be set.

PATENTANSPRUCH: Schaltung bzw. Steuerung von Glühlampenfeldern durch zeitlich aufeinanderfolgende Schaltung einzelner Glühlampen oder Glühlampenreihen, dadurch gekennzeichnet, daß an Stelle der bekannten mechanischen Verteilungsschalteinrichtungen lichtelektrische Schalteinrichtungen für die Verteilung der Steuer- bzw. Lampenstromimpulse auf das Glühlampenfeld verwendet werden. Angezogene Druckschriften: Deutsche Patentschrift Nr. 540 50z.PATENT CLAIM: Switching or control of incandescent lamp fields through successive switching of individual incandescent lamps or rows of incandescent lamps, characterized in that instead of the known mechanical distribution switching devices photoelectric switching devices for the distribution of the control or lamp current pulses can be used on the bulb field. Referred publications: German patent specification No. 540 50z.
