Abstract
An apparatus including an LED lighting system for use within AC current and comprising a multi-phase circuit design providing an improved power delivery means which allows one half of the LEDs in the system to be lit during any given one half of the alternating current cycle and the other half to be lit during the other half of the current cycle. Further, a heat sink module comprising heat sink fins mates with custom LED footprints such that the module is mated to the footprints on at least ⅓ of its total surface area. Finally, the LED lighting apparatus and system comprises a faceplate comprising a beveled aperture through said faceplate directly above each LED, and wherein said bevel angle is at least zero and no more than 120 degrees.
