Abstract
Provided is a flat fluorescent lamp comprising a main body with a plurality of discharge spaces therein, an electrode unit for applying voltage to the discharge spaces, said electrode unit formed on the surface of the main body, and at least one cooling pad adhered onto the electrode unit. The cooling pad may include at least two materials, which have different thermal conductivity with each other. Heat dissipation through the cooling pad minimizes the heat accumulation in the electrode unit, and resultantly prevents a pinhole in a glass plate at the electrode unit. Furthermore, driving voltage to be applied to the lamp can be increased beyond its limitation, thereby realizing a high brightness flat fluorescent lamp.
