    Abstract: In a backlight unit and an LCD apparatus having the backlight unit, in which the backlight unit includes a plurality of lamps and an inverter, the inverter provides the lamps with current. The inverter reduces current provided to the lamps to turn off the lamps. Therefore, currents are gradually decreased to reduce noise generated by the transformer when the lamps are turned off.

    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. The gas containing the mercury vapor is cooled at a temperature of about −38? to about 0? to form a liquid mercury. The liquid mercury is collected. Therefore, the broken pieces of the fluorescent lamps are heated at the temperature no higher than the boiling point of mercury so that an energy consumption and a size of the recycling apparatus are decreased, and a probability for the recycling apparatus to malfunction may also be decreased.
