DETECTOR CONTROLLED ILLUMINATING SYSTEM
First Claim
1. A processor controlled illuminating system for illuminating an area, said illuminating system comprising:
- a) a light fixture comprising at least one light source having at least one of controllable light intensity and spectral light distribution;
b) at least one detector adapted to sense information related to the instantaneous lighting conditions of entities present within said area and to pass the sensed information to a processor;
c) a processor adapted to use any of algorithms and look-up tables to process said sensed information and to determine the instantaneous lighting requirements for said area; and
d) a controller that is integral to said light fixture and is adapted to adjust at least one of the light intensity and the spectral light distribution of said at least one light source to provide said lighting requirements determined by said processor;
wherein, said processor is adapted to determine said instantaneous lighting requirements for said area by balancing tradeoffs between human factors and economic considerations related to visual task efficacy and to supplying said changing lighting requirements.

Abstract
An illuminating device coupled with sensors or an image acquisition device and a logical controller allows illumination intensity and spectrum to be varied according to changing user needs. The system provides illumination to areas according to the principles of correct lighting practice for the optimal performance of visual tasks in the most efficient, cost effective manner. Aspects of the invention include: lighting fixtures which adapt to ambient lighting, movement, visual tasks being performed, and environmental and personal conditions affecting illumination requirements at any given instant. Lighting fixtures have spatial distribution of spectrum and intensity, providing both “background” room lighting, and “task” lighting.
