Autonomous distributed lighting system
First Claim
1. A distributed lighting system comprising:
- a plurality of building lighting nodes on a network in communication with a central controller, at least one node being electrically connected to a plurality of peripherals, at least one of the peripherals being an LED lighting device, and at least one peripheral being a sensor or a light switch;
wherein each node includes a local processor and has a unique tag assigned to it by the central controller, and each unique tag is associated with at least one recipe stored locally at the node and executable by the local processor as well as also being stored remotely at the central controller, the recipe being a set of steps commanding through the local processor a plurality of actions taken by the node or peripheral in response to a one or more sensor or switch events or one or more commands from the central controller;
the system being constructed so that any node or peripheral can operate autonomously according to its tag and associated recipe without communication with the central controller;
the system also being constructed so that if a peripheral or node is moved to a new location in the network, the peripheral or node retains its original tag and its local processor executes the recipe associated with that original tag regardless of its location in the network.

Abstract
A system and method that uses a tag-driven network architecture controlled by one or more central controllers. Unique tags are associated with various system components such as remote switches, sensors and other peripherals. A tag is assigned to a node when the node is first entered into the network. A distributed policy creates relationships between tags of various different equipment. The tag typically defines what the policy is for a particular local node. The node executes the policy that is supplied in its tag by accessing a recipe associated with that tag. If a device is not working, other similar devices can take over its task simply by executing the recipe associated with the failed device'"'"'s tag instead of their own.

12. A distributed building lighting system comprising:
-
a plurality of nodes on a network in communication with a central controller, each node being electrically connected to one or more occupancy sensors and one or more LED lighting devices, each node having a unique tag ID assigned by the central controller when the node is first powered into the network, each tag ID being associated both at the node and at the central controller with a recipe of responses to sensor events, the recipe being executable by a local processor in the node; wherein, the sensor events include sensing occupancy in a room by one or more persons, the recipes including at least activating lights, deactivating lights and dimming lights, wherein the recipe may include adjusting brightness of a particular light based on time of day and outside ambient conditions; and wherein when a node is moved to a new location in the network, it retains its original assigned tag and continues to execute recipes on its local processor according to that original assigned tag. - View Dependent Claims (13, 14, 15)

16. An occupancy sensor for use in a network lighting system comprising:
-
first, second and third passive infrared sensors (PIRs) arranged with a coverage area of an approximate triangle in a occupiable space; an active IR motion detection sensor including an infrared light source and infrared detector driving a bandpass filter constructed to detect motion in said occupiable space, the active IR motion detection sensor being activated when the two of the PIRs detect motion; a processor executing instructions from a memory device, said instructions activating the active IR motion detection sensor when at least two of the PIRs detect motion and reporting possible occupancy of the occupiable space when the active IR motion detector also detects motion in the space. - View Dependent Claims (17, 18)
