Abstract

The device has a full bridge circuit supplied with a d.c. voltage (UBUS) with the lamp (LA) connected as the load for the bridge and a control circuit (T1, T2) alternately switching one diagonal voltage on and switching the other off. Both diagonals of the full bridge circuit have a regulated constant current source (OP1, OP2, S2, S4) for regulating the lamp current. Independent claims are also included for the following: a method of controlling the brightness of a gas discharge lamp.
