<p>PURPOSE: A light emitting diode driver is provided to highly suppress heat dissipation due to a resistive component by eliminating the resistive component on a current path. CONSTITUTION: A light emitting diode driver includes at least two light emitting diode strings(130), a direct current-alternating current converter(110), a transformer part(120), at least two bridge rectifiers(270), at least two balancing capacitors(150). The direct current-alternating current converter is used as alternating current power applied an alternating current voltage to the light emitting diode driver. The transformer part receives the alternating current voltage through an input port. The bridge rectifiers convert the alternating current voltage to a direct current voltage and supply the direct current voltage to each light emitting diode string. The balancing capacitors are in connection with the output port of the transformer part and the bridge rectifiers.</p> |
