Patent Images
1. A lighting control system, comprising:
- a plurality of zones;
a like plurality of lighting means such that each of said zones has its own lighting means;
a like plurality of sensors such that each zone has a sensor for determining if someone is present in said zone; and
a controller for individually controlling the level of light in each of said zones such that each zone will be illuminated at a first illumination level when it is occupied, at a third illumination level when it unoccupied but a neighboring zone is occupied, and at a third illumination level when neither itself nor a neighboring zone is occupied.

Abstract
A zoned lighting space (10) wherein an architectural space is divided in to a plurality of zones (16), each having its own sensor(s) and zone lights (18). The zone lights (18) are controlled by a controller (20) such that there are different lighting levels (55, 57, 59) depending upon whether a zone (16) is occupied, whether an adjacent zone (16) is occupied, whether some other zone (16) is occupied, and the like. A variable lighting control method (50) is adaptable such that fine control and adaptation for special circumstances can be achieved.

6. A method for controlling lighting within an area, comprising:
-
dividing the area into a plurality of zones; determining if someone is present in each of the zones; and illuminating each of the zones at a first level if someone is present in the zone, at a second level is no one is present in that zone but someone is present in an adjacent zone, and at a third level if no one is present either in that zone or in an adjacent zone.
