Abstract
The present invention provides a flat discharge lamp and the production method thereof. The flat discharge lamp comprises an upper substrate, a lower substrate and a discharge chamber disposed between the upper substrate and the lower substrate, wherein the discharge chamber is filled with an inert gas, and a plurality of first electrodes and second electrodes are arranged with one another disposed on the discharge chamber. Besides, each of the first electrodes and second electrodes is connected with one end and another end of an alternating power supply, respectively. The invention is characterized in that the discharge chamber is provided with fluorescent film coated on its interior surface and a plurality of third electrodes each disposed between the first electrode and the second electrode. Besides, all the third electrodes are connected to a common plane, or each of which is connected to the common plane, respectively. The third electrode is controllable to change the discharge energy and path when dielectrically impeded discharge is carried out between the first electrode and the second electrode.
