Abstract
Systems, methods and articles for providing centralized control of area lighting hours of illumination. An area illumination system includes a central control system operatively coupled to a plurality of luminaires through a data communications network. In some implementations, the data communications network may include a power-line power distribution system and/or a wired or wireless communications network. Each of the plurality of luminaires includes a local illumination control system, which may include a photosensor. The central control system identifies one or more luminaires as having a faulty local illumination control system and issues illumination commands to such luminaires through the data communications network so that the luminaires continue to operate normally without a working local illumination control system. The central control system may store data relating to luminaires having faulty illumination control systems, such as addresses, map data, routing data, or the like.
