Eitie großflächIge Entladungslampe, in der die UV-Strahlting 1)creits in Vakuum erzeugt und direkt auf (k-,ii Leuchtstoff fällt, 1-)ietei beleuchtungstechnisch große Vorteile. l,'rliliduiigsgümäß läßt sich (lies durch an sich beliebig gestaltete großflächige Ent-Iadungsgef äße geringer Querdimension erreiehen, in der die gleichmäßige Anwendung des Leuchtstoffes dadurch bewerkstelligt wird, daß der Entladungsstrom nacheinander mit genügender Geschwindigkeit über verschieden#e, die Fläche lückenlos überdeckende Pfade, geführt wird. Zweckmäßig wird dies durch Verwendung bekannter Mehrphasensysterne, z. B. des Drelistrornsysterns, erreicht, in dem drei Elek- troden in geeigneterAnordnung inDreieckschaltung oder vier in Sternschaltung angeschlossen werden, oder durch Anwendung geeigneter statischer oder magnetischer Drehfeld-er.The large-area discharge lamp, in which the UV radiation 1) is created in a vacuum and falls directly on (k-, ii fluorescent, 1-) has great advantages in terms of lighting technology. It can be achieved in a satisfactory manner by means of large-area discharge vessels of small transverse dimensions, which are designed as desired, in which the uniform application of the phosphor is achieved by the discharge current successively at sufficient speed over different paths that completely cover the surface This is expediently achieved by using known multiphase systems, e.g. the Drelistrorn system, in which three electrodes are connected in a suitable arrangement in a delta connection or four in a star connection, or by using suitable static or magnetic rotating fields.
