Abstract:
A flat fluorescent lamp includes a lamp body and an external electrode. The lamp body includes a plurality of discharge spaces. Each of the discharge spaces includes a first discharge region having a first space width and a first space length, a second discharge region having a second space width and a second space length, and a third discharge region having a third space width and third space length. The second discharge region is disposed between the first and third discharge regions. The second space width is smaller than the first and third space widths, and the second space length is smaller than the first and third space lengths. Thus, an electrode part of the flat fluorescent lamp is prevented from being blackened due to dendrite generated at the electrode part, so that the display quality of the liquid crystal display device having the flat fluorescent lamp can be improved.

Abstract:
There is provided a surface light source comprising a plurality of discharge channels, in which each end of the outermost discharge channel is expanded towards a sealing part. At least one of the plurality of discharge channels may include a curved surface part and a flat surface part on a top surface thereof. Both ends of the discharge channel may be formed to be higher than a middle portion thereof, and the discharge channels may be formed to be different in height. Accordingly, the discharge characteristic is improved and bad luminance uniformity is solved by variously changing the shape of the discharge channel forming the discharge space in a surface light source. Furthermore, the present invention solves the problems, such as failure in lighting at low temperature, channeling between adjacent channels, and maintains the quality of molded products.
