Abstract: A solid state igniter device for hot restrike of discharge lamps with an associated supply circuit. The ignitor device comprises a primary circuit with at least one solid state switch element controlled to switch to induce in the primary circuit a controlled oscillation phenomenon at a frequency greater than a megahertz and a secondary circuit including a resonant circuit with a high quality factor Q (at least 100), capable of resonating and producing a pulse signal for striking the discharge of the lamp, controlled through the controlled oscillation phenomenon produced in the primary circuit. A control unit acting on the switch element controls the oscillation phenomenon in a pulse mode as a function of the characteristics of the lamp and the power supply, wherein the control unit induces the controlled oscillation phenomenon for a predetermined time duration a programmable number of times in a predetermined time interval.
