Resonance igniter for discharge lamps

An igniter device (10) for discharge lamps (16) with an associated supply circuit (30) able to provide a supply signal (VAL) to the lamp (16) comprises: a primary circuit (12) with at least one switch element (20) controlled to switch to induce in the primary circuit (12) a controlled oscillation phenomenon at a frequency greater than a megahertz; a secondary circuit (14) capable of resonating and producing a signal (Vd) for striking the discharge of the lamp (16), controlled through the said controlled oscillation phenomenon produced in the primary circuit (12); and a control unit (22) acting on the switch element (20) for controlling the oscillation phenomenon as a function of the characteristics of the lamp (16), this unit (22) being capable of inducing the said controlled oscillation phenomenon a programmable number of times in a predetermined time interval (T1), each time for a predetermined time duration (T2).
