Abstract:
1. A flat fluorescent lamp, comprising: a chamber, comprising; a first substrate; a second substrate facing the first substrate; an edge frame disposed between the first substrate and the second substrate; a plurality of spacers disposed between the first substrate and the second substrate; a discharge gas disposed inside the chamber; a plurality of first electrodes disposed on the first substrate; a plurality of second electrodes disposed on the first substrate, wherein one of the second electrodes is disposed between every two neighboring first electrodes, a plurality of first protruding points is disposed on a first side of each of the first electrodes and each of the second electrodes, the first side of each of the first electrodes and the first side of each of the second electrodes face to a same side of the flat fluorescent lamp, a plurality of second protruding points is disposed on a second side of each of the first electrodes and each of the second electrodes, and in the same first electrode and second electrode, the first protruding points and the second protruding points are alternately disposed, a first light-emitting region is formed between the first protruding points and the corresponding first electrodes and second electrodes opposite to the first protruding points, a second light-emitting region is formed between the second protruding points and the corresponding first electrodes and second electrodes opposite to the second protruding points, the first light-emitting region and the second light-emitting region are one of the entirely not overlapping and partially overlapping, and the first light-emitting region and the second light-emitting region formed by the first protruding points disposed on the first side of the same first electrode are adjacent to each other and arranged alternately; a dielectric layer covering the first and the second electrodes; and a fluorescent material disposed inside the chamber.
