FIELD: illumination devices. SUBSTANCE: device has diodes which shape bridge rectifier, choke which one terminal is connected to power supply line and which another terminal is connected to opposite terminals of two diodes, two identical serial circuits of resistors and capacitors. Common point of both circuits is connected to opposite terminals of two another diodes and to second wire of power supply line. Free terminals are connected to output of bridge rectifier and electrodes of gas-discharge lamp. EFFECT: increased functional capabilities. 1 dwg
