Abstract

For an assembly of differing discharge-lamps, for each lamp of the assembly, an ideal air-gap value is determined for the stabilising choke for this lamp, and on the basis of the ideal air-gap values thus determined, there are chosen a minimum air-gap at least approximately suitable for one or more lamps (A, B, C, D, G) of the assembly, a maximum air-gap at least approximately suitable for one or more other lamps (I) of the assembly, and at least one intermediate air-gap at least approximately suitable for one or more of the remaining lamps (E, F, H) of the assembly, so as to at least approximately cover the differing air-gap requirements. An assembly of stabilising chokes is produced comprising a first choke produced by means of first magnetic- circuit elements each forming the chosen minimum air-gap, a second choke produced by means of second magnetic-circuit elements each forming the chosen maximum air-gap and one or more intermediate chokes produced by means of the first and second magnetic-circuit elements to form the chosen intermediate air-gap(s) by combining the minimum and maximum air-gaps.
