摘要： The invention relates to an apparatus for control of plural LED lightings and more particularly to an apparatus having a constant voltage/constant current control circuit and an equal load control circuit for load driving of plural LED lightings. An apparatus according to the invention comprises: a current regulator which receives an input power and controls a current value through an internal resistance value with respect to an LED load capacity; a ripple improvement section which prevents an output voltage from being rectified above or equal to a reference input voltage when the input power is converted into a DC power (pulsating current) by a rectifier; a rectifier for rectifying an input AC power; an optimal load power generator where a pulsating current outputted from the rectifier is divided into a load voltage of a gate terminal of a control circuit; a primary constant voltage controller and a secondary constant voltage-clamp controller, which control an output voltage and a pulsating current from the optimal load power generator to a constant voltage with a preset value; an output controller which generates from the constant voltage being generated a constant current of a required load power; and an output ripple improvement section which removes from a signal with a constant current controlled by the output controller a ripple component that can be induced to a DC voltage.
