Abstract:
1. A flat fluorescent lamp with a plurality of channels, comprising: a first substrate on which a plurality of channels are formed; a second substrate that is assembled to the first substrate to form a discharge space within each of the plurality of channels, wherein each of the plurality of channels has an emitting section at a middle thereof and electrode sections on opposite ends thereof, the emitting section being connected to the electrode sections, and wherein a transverse cross-sectional area of the electrode sections is larger than a transverse cross-sectional area of the emitting section; first and second upper electrodes formed at first and second ends, respectively, of the first substrate over the electrode sections; first and second lower electrodes formed on first and second ends, respectively, of the second substrate under the electrode sections; and extending electrodes that extend outward from the first lower electrodes and the second lower electrodes, and wherein a length of each of the extending electrodes varies depending upon a temperature of adjacent channels.
