Claims:

1. A channel structure of a flat fluorescent lamp, defining therein a sealed discharge space having a continuous seφentine shape and being partitioned into a plurality of communicating discharge channels by a plurality of partition walls, with one or more electrodes provided in the discharge space, wherein the discharge channels have different widths which are reduced in a direction away from a location of a hot electrode.

2. The channel structure of the flat fluorescent lamp according to claim 1, wherein the widths of the discharge channels vary in accordance with a size of the flat fluorescent lamp, characteristics and intensity of electricity to be applied to the electrodes, and distances from the electrodes.

3. The chamiel structure of the flat fluorescent lamp according to claim 1, wherein, when the flat fluorescent lamp is a hot-cold-hot type lamp, the widths of the discharge channels are reduced in directions from opposite ends of the lamp, having hot electrodes, toward an intermediate portion of the lamp.

4. The channel structure of the flat fluorescent lamp according to claim 1, wherein, when the flat fluorescent lamp is a hot-cold type lamp, the widths of the discharge channels are reduced in a direction from a first end of the lamp, having a hot electrode, toward a second end of the lamp.
