METHODS, APPARATUS AND SYSTEMS FOR PROVIDING OCCUPANCY-BASED VARIABLE LIGHTING

摘要

A presence and an absence of a person or object of interest (an "occupant") is detected, and an occupancy sensor signal is generated indicating an active state In which the presence of the occupant is detected, and an inactive state in which the absence of the occupant is detected. An ambient light sensor detects the ambient light level and generates an ambient light sensor signal indicating the ambient light level. Dimmable illumination is generated at a first level, based on the ambient light level, corresponding to the active state and a second level corresponding to the inactive state. A transition delay time between an onset of the inactive state and a transition between the first dimming level and the second dimming level may be controlled. The first dimming level, the second dimming level, and/or the transition delay time may be variably set or controlled locally or via a remote device.
