Patent Images
1. A lighting network comprising:
- a plurality of lights, each of said lights having means to communicate status information relating to said light to a control system, said status information comprising at least one value for an operational parameter of said light;
said control system comprising processing means for;
receiving said status information;
performing a statistical analysis on said values to determine a baseline value; and
comparing each of said values to said baseline value and determining whether the value corresponding to each of said lights deviates from said baseline value by a predetermined amount.

Abstract
A network of lighting elements controlled by a control system, in which the control system receives and analyzes operating conditions from the lighting elements in the network, from which it can determine whether any lighting elements are operating at unacceptable levels. The analysis is carried out by averaging the values received from the lighting elements to determine a baseline value and determining whether any deviate from the baseline value by more than a pre-determined amount. Alternatively, the analysis may be done by finding the distribution of the values and mode value, and determining whether any individual values are outside an acceptable distribution.
