LIGHTING SYSTEM WITH A DIELECTRIC BARRIER DISCHARGE LAMP AND WITH A CIRCUIT PROVISION FOR THE GENERATION OF SEQUENCES OF VOLTAGE IMPULSES.

摘要

AN ELECTRIC CIRCUIT ASSEMBLY IS DESCRIBED TO GENERATE VOLTAGE IMPULSE SEQUENCES FOR THE OPERATION OF DIELECTRICALLY INHIBITED DISCHARGES, AND THAT INCLUDES A SERIAL CIRCUIT PROVIDED WITH A SWING CIRCUIT INDUCTION COIL (TR2 - A) WITH T1 - A) , A PULSE GENERATOR (OS) CONTROLLING SUCH SWITCH (T1), A CURRENT VALVE (D1) PARALLEL MOUNTED WITH SUCH SWITCH (T1), A FEEDER CONDENSER (C2) EQUALLY MOUNTED IN PARALLEL WITH SUCH SWITCH) , AN ELEMENT (TR2 - B, A ", B") FOR COUPLING A LAMP (LA1) AT LEAST TO A DIELECTRICALLY INHIBITED ELECTRODE AND, OPTIONALLY, AN INTERMEDIATE FEEDBACK CONDENSER (C1) PARALLEL MOUNTED TO SUCH CIRCUIT SERIES OF THE SUCH INDUCTION COIL OF THE SWING CIRCUIT (TR2 - A) AND OF SUCH CONTROLLED SWITCH (T1). THE COUPLING ELEMENT OF A LAMP INCLUDES PARTICULARLY TWO TERMINALS (A ", B") AND THE SECONDARY WINDING (TR2 - B) OF A SELF-TRANSFORMER (TR - 2), MOUNTED BETWEEN A FIRST SWITCH POLE (T1) AND THE TERMINAL CORRESPONDING (A "), CHARACTERIZED BECAUSE THE PRIMARY WINDING (TR2 - A) OF SUCH SELF-TRANSFORMER (TR2) ACTS AS THE INDUCTION COIL OF THE SWING CIRCUIT. THE SECOND TERMINAL (B") IS CONNECTED TO THE SECOND POLE OF THE SECOND SWITCH (T1). IN USE, THE MENTIONED SWITCH (T1) IS OPENED AND CLOSED ALTERNATIVELY, IN ACCORDANCE WITH THE RHYTHM OF THE CONTROL SIGNALS OF THE PULSE GENERATOR (OS), TO GENERATE A SEQUENCE OF VOLTAGE PULSES SEPARATED BY INTERRUPTION TIMES IN THE ELECTRODES DIELECTRICALLY INHIBITED FROM A LAMP CONNECTED TO THE TERMINALS (A ", B").
