<p>PURPOSE: An LED driving circuit is provided to remove ripples using a switching filter which operates as an emitter follower at the secondary side of the LED driving circuit, thereby reducing the blinking of the LED lamp. CONSTITUTION: An LED driving circuit includes a filter driver (20) which includes a resistance and a condenser in series at both ends of the secondary side the LED driving circuit; and a switching filter (30) which operates as an emitter follower according to the signal filtered by the filter driver and switches the voltage induced to the secondary side to the LED lamp.</p> |
