Abstract

An electronic power supply unit (4)for discharge lamps, comprises an electronic power supply circuit (8) suitable to receive a mains voltage in input (V cc ) and to generate, on the two output terminals (18), a triggering voltage (V imp ) to trigger an associable discharge lamp (12). Advantageously, the power supply unit (4) sends the output terminals (18) two impulse voltages (± V imp ) of the same value and opposing polarities, so as to generate a total power supply voltage of double the value of the voltages (± V imp ) of the single output terminals (18) and suitable to trigger the lamp (12).
