<p>PURPOSE: An LED driving circuit is provided to perform a burst dimming control at a narrow space by including a controller which controls the operation of a DC-AC converter. CONSTITUTION: An LED driving circuit includes LED strings(132,134), a DC-AC converter, a transformer(120), a rectifier, and a controller(240). The DC-AC converter converts DC power into AC power. The rectifier rectifies the AC power from the transformer and supplies rectified power to the LED strings. The controller controls the operation of the DC-AC converter according to a burst dimming signal applied from the outside.</p> |
