Intelligent area lighting system
An area lighting system is composed of a plurality of lighting elements that are responsive to the movement and progression of a user through the area. Each lighting element comprises at least one light, means for powering the lighting element, a processor, communication means and is associated with a motion sensor. Detection of a user is communicated to other lighting elements that provide an appropriate level of illumination depending on the distance from the user. The lighting elements are substantially self-configurable and may be set for either a radial proximity lighting protocol or a path network lighting protocol.
