Electric induction device e.g. ionized gas based lighting device, for e.g. forming light panel, has generator electrode connected to high tension radio-frequency generator and placed at short distance from solid insulating casing

摘要

The device has a generator electrode (1) placed at shorter distance from a solid insulating casing (3) containing a gas or a gas mixture (2), where the casing is covered with a cover (4). The electrode is electrically connected, by a short wire (7), to an end of a high tension radio-frequency generator (6) whose other end is connected to the ground (8). The cover has luminescent material layers disposed on an inner side of the casing.
