An LED lighting device comprising a plurality of light-emitting diodes (LED) and a power supply that receives alternating-current (AC) power from an input node and provides rectified direct-current (DC) power to the LEDs. The LED lighting device further comprises a capacitive power-factor compensation means and a bridge rectifier, wherein the capacitive power-factor compensation means is electrically downstream from the input node and electrically upstream from the bridge rectifier, and wherein the bridge rectifier is electrically downstream from the capacitive power-factor compensator means and electrically upstream from the LEDs; and a heat sink that contains said power supply, wherein said heat sink comprises a plurality of carriers, on which the LEDs are mounted. The LED lighting device does not include an electronic module that performs digital computation of software.
