Abstract
A lighting system and method for controlling illumination of the same upon detection of a user in at least one of a first detection area and a second detection area. The lighting system can include a lighting fixture having one or more lighting sources and at least two sensors associated with separate detection areas. Each sensor can send a signal to a controller associated with the lighting fixture, and the controller can be configured to vary the illumination of one or more of the lighting sources depending on the each sensor's detection area. The present subject matter facilitates energy savings since areas away from an occupied area are not illuminated. Communication between neighboring lighting fixtures is not required since each lighting fixture can detect the presence of a user in an area proximate an adjacent lighting fixture in order to trigger illumination of the lighting fixture.
