Abstract:
1. A flat fluorescent lamp, comprising: a back substrate; a front substrate made of a transparent material and mounted on the back substrate through a sealing member disposed therebetween, to be spaced from the back substrate by a predetermined interval; a plurality of partitions alternately disposed between the back substrate and the front substrate, to define a discharge channel of a zigzag shape therebetween, the partitions being in close contact with the front substrate; a fluorescent material layer coated along a surface of the discharge channel defined by the partitions; first electrodes disposed in spaced apart relation and extending substantially completely along both sides of an outer surface of the front substrate; second electrodes disposed in spaced apart relation and extending substantially completely along both sides of an outer surface of the back substrate and facing the first electrodes; and a reflective layer formed of a combination of a white ceramic material and a glass material to cover the entire back substrate and an upper portion of the electrode of the back substrate; wherein apertures of the electrodes are formed to have sizes decreasing gradually from an inner side of each electrode to an outer side of the fluorescent lamp.
