1. A lighting element for use in a lighting system, comprising:
- a light source;
a processor;
a detector for determining the coordinates of the lighting element;
a transceiver; and
said processor being programmable to selectively cause said light source to illuminate according to the distance of said lighting element from an other lighting element upon receipt of a transmission from said other lighting element.

Abstract
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.

17. A method of illuminating an area comprising:
-
deploying a plurality of lighting means in said area, each having associated coordinates; detecting the presence of a user of the area in the vicinity of a first of said lighting means; and one or more others of said plurality of lighting means each responding to said detecting by determining a distance between its coordinates and the coordinates of said first lighting means, and illuminating according to a lighting protocol based on said distance. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A lighting element for use in a lighting system, comprising:
-
a light source; a processor; a detector for determining the coordinates of the lighting element; a transceiver; and said processor being programmable, upon receipt of a transmission from an other lighting element, to determine and implement a lighting protocol for said light source based on the distance between said coordinates and the coordinates of said other lighting element; said lighting protocol including activation parameters selected from the group comprising;
whether to illuminate said light source, a rate at which to illuminate said light source, and an intensity to which said light source is to be illuminated. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
