Japanese Patent JP3036694

Kind Code:

U

Abstract:

A circuit arrangement for igniting and operating a high-pressure discharge lamp is provided with a switching device, inductive device and a rectifier which together form a Buck converter, connected to input terminals for connection to a supply source and output terminals for connection of the lamp. The lamp is supplied with a current through periodic switching of the switching device alternatively into a conducting and a non-conducting state by means of a switch-on and switch-off signal, respectively. The inductive device includes a primary and a secondary winding with the secondary winding forming part of an integration network for generating the switch-off signal. The secondary winding also forms part of a voltage divider network for generating the switch-on signal. A very simple circuit arrangement is thereby achieved.
