FIELD: instrument making.
SUBSTANCE: invention can be used for switching on the luminescent lamp both with a starter and without it. To this end, two diodes connected in series are connected parallel to the outputs of every lamp electrode so that the cathode output of an electrode is connected to anode output of the other electrode. Here note that the circuit terminals are connected via current-limiting element to the points of connection between diodes.
EFFECT: wider range of the lamp operating currents, longer life.
