Abstract

Für eine Versorgungseinheit (1) einer Metalldampfhochdrucklampe (2) wird vorgeschlagen, zur Entlastung des vorhandenen temperaturabhängig schaltenden Schutzschalters (9) eine Überwachungseinrichtung (18) vorzusehen, die die Netzspannung überwacht. Nimmt die Netzspannung Werte an, bei denen die Metalldampfhochdrucklampe (2) leidet (Unterspannung) oder Ströme führt, die von dem Temperaturschalter (9) nicht mehr sicher abgeschaltet werden können, unterbindet die Überwachungseinheit (18) die Erzeugung von Zundintpulaen, d.h. sie sperrt die Zündeinrichtung (12).

Figure imgaf001
For a supply unit (1) of a metal vapor high-pressure lamp (2) is proposed to provide relief of the existing temperature-dependent switching circuit breaker (9), a monitoring device (18) which monitors the mains voltage. If the mains voltage assumes values at which the metal vapor high-pressure lamp (2) suffers (undervoltage) or carries currents which can no longer be reliably switched off by the temperature switch (9), the monitoring unit (18) prevents the generation of ignition batteries, ie blocks them Ignition device (12).
