INVERTER TRANSFORMER AND DISCHARGE LAMP LIGHTING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To solve the problem of an discharge lamp lighting circuit becoming large size due to its occupying a wide space on a printed circuit board with an inverter transformer. SOLUTION: One primary winding wire 30 and plural secondary winging wires 40 are provided, and the respective secondary winging wires 40 are coupled electromagnetically to the primary winding wire 30 with the same degree of coupling. Then, the respective secondary winding wires 40 of this inverter transformer are connected to respectively different discharge lamps.
