Abstract

A variable frequency inverter (30) supplies a load circuit (40), incorporating two fluorescent lamps (LA1, LA2). An integrated control circuit (17) includes a transceiver (10), to which commands are addressed for adjustment of the brightness and operational mode. With the lamps switched off, the inverter (30) is switched by a driver circuit (31) into SLEEP mode either immediately or after a preset delay, to be reactivated by reception of a fresh brightness command. It is fed from the mains via an on/off switch (S1) and a rectifier (20).
