  1. PATENTANSPRUCH : Tunnelbeleuchtungsregelung, bei der die photoelektrisch gemessene Tageslichthelligkeit als Führungsgrösse und eine von der Grösse des Lichtstromes der Tunnelbeleuchtung abhängige Messgrösse als Regelgrösse in eine Regelschaltung so eingeführt werden, dass die Tunnelhelligkeit in einem bestimmten EMI2.2 elektrischer Strommessgeräte erfasste Grösse der Lampenströme als die von der Grösse des Lichtstromes der Tunnelbeleuchtung abhängige Messgrösse verwendet wird.
