    • PROBLEM TO BE SOLVED: To provide a method of controlling the operating resistance itself of a plurality of discharge lamps, in an electronic circuit for lighting the discharge lamps connected to a common voltage source, and to provide the electronic circuit for executing the method. SOLUTION: The electronic circuit is provided for lighting the plurality of discharge lamps La connected to the common voltage source U. It comprises a current balancing circuit for splitting the flow of a predetermined current between the plurality of discharge lamps La. In each of the discharge lamps La, at least one desymmetrizing module DBp, DBn is arranged for intentionally desymmetrizing the individual lamp current I L so that a set value for the current flowing in each of the discharge lamps La is monotonously increased as the impedance of the discharge lamp La is increased.
