Comparative study of smart lighting grids with LEDs operated with concentrated, localized or distributed control

Smart lighting grids, consisted of smart luminaries with capability to communicate with each other, have great potential to reduce power consumption in the sphere of artificial illumination. This paper provides comparative study of concentrated, localized or distributed control approaches of smart lighting grids and summarizes mentioned approaches by comparing safety, functionality and expandability factors. Afterwards the illumination diagrams are drawn with mathematically and experimentally acquired data for each of the proposed control methods, energy consumption by each of approaches is calculated and discussed.
