Luminaire with ambient sensing and autonomous control capabilities
First Claim
1. An illumination system, comprising:
- a luminaire including at least one light source;
a controller to provide a signal output that autonomously adjusts a luminous output level of the at least one light source, the controller including at least one processor;
a sensor communicably coupled to the controller to provide a signal that includes information indicative of an occurrence or a lack of occurrence of a defined event; and
at least one set of machine executable instructions that when executed by the at least one processor cause the at least one processor to;
determine whether the sensor is in at least one of;
an operational mode or a failure mode;
wherein responsive to a determination that the sensor is in the failure mode, the processor provides the signal output based at least in part on at least one value determined by the processor until a subsequent determination by the processor that the sensor is in the operational mode; and
wherein responsive to a determination that the sensor is in the operational mode, the processor provides the signal output based at least in part on the information included in the signal provided by the at least one sensor until a subsequent determination by the processor that the sensor is in the failure mode.

Abstract
A number of luminaires can be communicably coupled and networked. Some or all of the luminaires may be equipped with a number of sensors including motion sensors. Upon detecting motion of an object in the vicinity of a luminaire, the luminaire can increase the luminous output of the lighting subsystem in the luminaire and communicate a targeted or broadcast output signal to some or all of the remaining luminaires in the network. The output signal may variously contain data indicative of one or more parameters related to motion of the object (direction of travel, velocity, etc.) or one or more parameters related to the increased luminous output of the luminaire. Responsive to the receipt of an output signal generated by another luminaire, the luminaire may autonomously adjust the luminous output of the lighting subsystems responsive to an event detected by the other luminaire.

5. A controller to provide a signal output to adjust the luminous output level of at least one luminaire light source responsive at least in part to at least one of:
- a sensor signal that includes information indicative of an occurrence or lack of occurrence of a defined event, or at least one value determined by the controller, the controller comprising;
at least one processor; and at least one machine executable instruction set that when executed by the at least one processor causes the processor to; determine whether a sensor providing the sensor signal is in at least one of;
an operational mode or a failure mode;wherein responsive to a determination that the sensor is in the failure mode, the processor provides the signal output based at least in part on at least one value determined by the processor until a subsequent determination by the processor that the sensor is in the operational mode; and wherein responsive to a determination that the sensor is in the operational mode, the processor provides the signal output based at least in part on the information included in the signal provided by the at least one sensor until a subsequent determination by the processor that the sensor is in the failure mode. - View Dependent Claims (6, 7, 8, 9)
