Solution for dynamic lighting control

摘要

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.

主权项

1. A lighting fixture, comprising:
a controller; a first sensor configured to send a signal to the controller upon the detection of a presence of a user in a first detection area; and a second sensor configured to send a signal to the controller upon the detection of a presence of a same or different user in a second detection area; wherein the controller is configured to provide varying levels of illumination based at least in part on the signals received from the first sensor and the second sensor; wherein the first detection area extends to an area proximate an adjacent lighting fixture and wherein the second detection area is proximate an area beneath the lighting fixture; and wherein the controller is configured provide an output that causes the lighting fixture to have a reduced illumination when the first sensor detects the presence of a user in the first detection area and the second sensor does not detect the presence of a user in the second detection area.
