ABSTRACT:
The invention relates to a method of manufacturing an inductive stabilizing ballast for a gas and/or vapor discharge lamp.
According to the invention, after placing the laminations in and about the coil, part of each lamination is turned about an axis which is parallel to the center line of the electric coil so that the lamination parts are tightly turned against the electric coil. This leads to a satisfactory thermal contact between the coil and the casing so that the removal of heat from the coil is enhanced.
