Abstract: In an eco-friendly method of recycling a fluorescent lamp capable of reducing energy consumption and a recycling apparatus for performing the recycling method, broken pieces of fluorescent lamps are heated at a temperature of about 100? to about 330? to form a gas containing a mercury vapor.

Abstract: A flat fluorescent lamp includes a lamp body and first external electrodes. The lamp body has discharge spaces formed therein. The first external electrodes are disposed at a first end portion of an outer surface of the lamp body and a second end portion that is opposite to the first end portion to define a first region where the discharge spaces overlap the first external electrodes and a second region where the discharge spaces do not overlap the first external electrodes. Each of the discharge spaces has a first width at the first region and a second width that is smaller than the first width at the second region. Therefore, an overlapping region between the first external electrodes and the discharge space increases to lower the discharge voltage.

Abstract: A light source for generating a planar light includes a first substrate, a second substrate and a first external electrode. The second substrate includes a plurality of discharge space portions, a plurality of space dividing portions and a plurality of recesses formed on end portions of a predetermined number of the discharge space portions. The discharge space portions are spaced apart from the first substrate to form a plurality of discharge spaces. The space dividing portions make contact with the first substrate between the discharge space portions. The recesses are recessed toward the first substrate. The first external electrode is formed on the second substrate. Therefore, a luminance of the planar light is uniformized to improve an image display quality.
