<p>PURPOSE: An apparatus for adjusting the current valance of a light emitting diode is provided to reduce manufacturing costs while preventing deterioration since there is no switch element for supplying an overvoltage. CONSTITUTION: In an apparatus for adjusting the current valance of a light emitting diode, the current balance adjustment device(100) of a light emitting diode comprises a power factor correction part(102), a DC-AC converter(104), a lighting-emitting area(106), an inverter unit(108), a current sensing part(110), and a DC-AC driver IC(112). The DC-AC converter receives a DC with compensated power factor and coverts it to an AC. A lighting-emitting area comprises a first lighting-emitting area(106a) and a second lighting-emitting area(106b). The lighting-emitting area receives the AC and radiates light through positive driving and negative driving.</p> |
