Patent ID: 8384312

Claim:
A power distribution system for supplying electrical power to a plurality of lighting units, the power distribution system comprising: at least one user interface connecting with a power source and comprising a first pairing setting unit, wherein the first pairing setting unit comprises a first power line communication unit and a first controller in electrical connection with the first power line communication unit; a plurality of second pairing setting units, each of the plurality of second pairing setting units electrically connected with one of the lighting units, wherein each of the second pairing setting units comprises a second power line communication unit and a second controller in electrical connection with the second power line communication unit; and a power line, electrically connected with each of the lighting units and electrically connected between the first pairing setting unit and the second pairing setting units, wherein each of the second pairing setting units receives an electrical signal supplied from the first pairing setting unit and, based on the electrical signal, determines whether to turn on the one of the lighting units associated therewith, whereby the lighting units in electrical connection with the power line are controllable individually.
