Patent ID: 8536802

Claim:
A lighting fixture to provide variable occupancy-based lighting, the lighting fixture comprising: a housing; at least one occupancy sensor, disposed in the housing, to provide occupancy information; a plurality of light emitting diodes (LEDs) disposed in the housing to provide the variable occupancy-based lighting at a plurality of light levels; a power management module (PMM), disposed in the housing and operatively coupled to the at least one occupancy sensor and the plurality of LEDs, to adjust the variable occupancy-based lighting based at least in part on the occupancy information provided by the at least one occupancy sensor, the power management module including: a memory to store lighting parameters, wherein the lighting parameters include at least an active power output level of the plurality of light levels, an inactive power output level of the plurality of light levels, and a sensor delay; and a digital light agent controller to implement a state machine to analyze the occupancy information and control the plurality of LEDs based at least in part on the lighting parameters in the memory so as to provide the variable occupancy-based lighting at the active power output level of the plurality of light levels or the inactive power output level of the plurality of light levels; and a data interface to provide the occupancy information to a management module and to receive a changed sensor delay from the management module, wherein the management module includes a processor to analyze past patterns of the occupancy information and to generate the changed sensor delay based on the past patterns of the occupancy information so as to provide at least one of a reduction in energy consumption and an optimization of at least one process associated with providing the variable occupancy-based lighting.
