Abstract: An electrodeless fluorescent lamp 10 has an envelope 12 that includes a chamber 14. A core 16 of magnetic material, preferably ferrite, is positioned in the chamber 14 and has a first winding 18 surrounding the core and having first and second lead-in wires 20, 22, attached to a high frequency voltage supply or ballast 24. A second winding 26 surrounds the core 16, respective turns of the second winding 26 being located adjacent turns of the first winding 18 and electrically insulated therefrom. The second winding 26 has a free end 28 and has another end 30 connected to one of the lead-in wires, for example 20. A braided sheath 32 surrounds the other of the lead-in wires 22. The first winding 18 is generally called the RF antenna. The braided sheath 32 is connected to the local ground. This inexpensive solution alone reduces the conductive EMI level sufficiently to pass all existing regulations on such interference with significant reserve.

This integrated bus electrode is flush with the edge of the display and is connected to a flexible printed cable which connects to drivers. Alignment marks are placed on the integrated bus electrode to locate exactly where the flexible printed cable attaches to the integrated bus electrode.
