CIRCUIT ARRANGEMENT

摘要

The invention relates to a circuit arrangement for supplying a lamp with a DC lamp current comprising only passive components and equipped with mains input terminals for connection to poles of a supply voltage source, rectifying means, equipped with two input terminals, coupled to the mains input terminals, and two output terminals, for generating a DC voltage out of a low frequency AC voltage supplied by said supply voltage source, capacitive means, coupled between the mains input terminals and the output terminals of the rectifying means, a load circuit coupled to the output terminals of the rectifying means and comprising terminals for connection to the lamp, and inductive means. In accordance with the invention the load circuit is equipped with a series arrangement of only passive components, said series arrangement connecting the output terminals of the rectifying means and comprising the inductive means and the terminals for connection to the lamp. The circuit arrangement is simple and inexpensive and is very suitable for operating a discharge lamp and for being incorporated into a compact lamp.
