Abstract

A lighting and control system is described. One embodiment of the lighting and control system includes a lighting node and a controller. The lighting node may include a light emitting diode configured for illumination and further configured for optical communication with the controller, a node radio device configured for radio communication with the controller, and a node memory configured to store a node identifier and a group identifier. The controller may include an optical sensor configured to sense illumination of the lighting node and further configured for optical communication with the lighting node, a controller radio device configured for radio communication with the lighting node, and a controller memory configured to store a group identifier. The lighting node and the controller may each further include a power supply and a processor. In one embodiment, the lighting node and the controller belong to a wireless mesh network.

Claims

1. A lighting and control system having a plurality of lighting nodes, and a controller, the system comprising:

the plurality of lighting nodes, wherein each lighting nodes includes;

a lamp configured for providing an illumination, wherein the illumination is user-controlled to provide a configurable lighting experience,

wherein the lamp comprises one or more light emitting diodes;

the lamp further configured for optical communication of a spectral content of the illumination with the controller;

a node radio device configured for radio communication with the controller, and

a node memory configured to store a node identifier; and

the controller including;

an optical sensor configured to sense the spectral content of the illumination of at least one lighting node,

a controller radio device configured for radio communication with the plurality of lighting nodes, and

a controller memory configured to store at least some of the node identifiers of the plurality of lighting nodes and one or more color profiles to be targeted by the illumination provided by at least some of the plurality of lamps,

wherein the controller is physically separate from each of the plurality of lighting nodes, and further wherein the controller is used to remotely control the illumination of at least one of the plurality of lighting nodes via the controller radio device based upon the sensed characteristics of the illumination of the at least one of the plurality of lighting nodes, wherein the controller radio device sends a command to the at least one of the plurality of lighting nodes by using the node identifier associated with the lighting node.

2. The lighting and control system of claim 1, wherein each node radio device is configured for radio communication with another lighting node.

3. The lighting and control system of claim 1, wherein each node radio device further includes a radio receiver.

4. The lighting and control system of claim 1, wherein each node radio device further includes a radio transceiver.

5. The lighting and control system of claim 1, wherein each lighting node is configured as a mesh network node.

6. The lighting and control system of claim 1, wherein the at least one of the plurality of lighting nodes is configured for calibration of illumination by the controller utilizing one of the one or more color profiles.

7. The lighting and control system of claim 1, wherein the at least one of the plurality of lighting nodes is configured for recalibration of illumination by the controller utilizing one of the one or more color profiles after the lighting node decalibrates.

8. The lighting and control system of claim 1, wherein the node radio device is configured for radio communication with another controller.

9. The lighting and control system of claim 1, wherein the node radio device is configured for radio communication with an external system.

10. The lighting and control system of claim 1, wherein the node radio device is configured for communication with another controller.

11. The lighting and control system of claim 1, wherein the optical sensor is configured to receive illumination from the lighting node without receiving illumination from an adjacent lighting node.

12. The lighting and control system of claim 1, wherein the controller is configured to calibrate the illumination of the at least one of the plurality of lighting nodes utilizing one of the one or more color profiles.

13. The lighting and control system of claim 1, wherein at least one of the color profiles comprises a target spectral content of a target illumination captured by the optical sensor, and further wherein the controller radio device sends a command to the at least one of the plurality of lighting nodes to provide the illumination having substantially the target spectral content.

14. The lighting and control system of claim 1, wherein the node memory is further configured to store a group identifier for each of the plurality of lighting nodes, wherein the controller addresses radio communications to a group of lighting nodes having the same group identifier by using the group identifier corresponding to the group of lighting nodes.
