ELECTRODE COIL FOR DISCHARGE LAMPS AND METHOD FOR PRODUCING SUCH AN ELECTRODE COIL

摘要

The invention relates to electrode coils for discharge lamps having a coiled wire (1) which is wound around by a braiding wire (2). The coiled wire (1) has both turns (II) with an essentially circular crosssection and turns (I, III) with an oval cross-section. In order to produce the bar-shaped coil according to the invention, the unit comprising the coiled wire (1), the first core wire (3) and the braiding wire (2) is wound around a second core wire (4) which is flattened in places. Unrolling of the braiding wire (2) is prevented thereby. Production of the coil is cost-effective, since only two core wires are required and the coil ends are not fused.
