FIELD LIGHTING INSTALLATION

摘要

A field lighting installation includes a plurality of series connected light fittings, supplied from an A.C. mains via a converter unit, which is adapted to convert the substantially constant voltage obtained from the mains to a substantially constant current in departing lines containing the light fittings. A current controlled regulating unit (12) is associated with each light fitting or group of fittings for regulating the current through the associated lamp or lamps (6).
