Abstract

A lighting node is described. One embodiment of the lighting node includes a lamp, a radio device, and a memory. The lamp is configured for generating illumination. The radio device is configured for radio communication. The radio device is configured to remotely receive a color profile from the controller. The lamp is also configured to generate illumination to substantially match the received color profile. The memory is configured to store a group identifier for the lighting node.

Claims

1. A lighting node comprising:

a lamp configured for generating illumination;

a radio device configured for radio communication;

a memory configured to store a group identifier for the lighting node; and

wherein the radio device is configured to couple to a remote controller by registering the group identifier to the remote controller;

wherein the radio device is configured to remotely receive a color profile, from the remote controller, to perform a background automatic calibration to compensate for decalibration of the lamp overtime, while the remote controller is oriented towards the lamp and while the lightning node is engaged to execute another command from the remote controller initiated by a user; and

wherein during the background automatic calibration, the radio device is configured to receive multiple calibration commands in sequence from the remote controller as feedback to adjust the generated illumination until the generated illumination matches the color profile; and

wherein the lamp is configured to adjust the generated illumination based on the multiple calibration commands in sequence.

2. The lighting node of claim 1, wherein the radio device is configured to remotely receive a first color profile of light generated by another lighting node with the same group identifier;

and wherein the lamp is configured to generate illumination to substantially match the received color profile.

3. The lighting node of claim 1, wherein the radio device is configured to remotely receive a second color profile of light generated by the lighting node recorded externally at a previous time;

and wherein the lamp is configured to generate illumination to substantially match the received color profile.

4. The lighting node of claim 1, wherein the radio device is further configured for radio communication with another lighting node.

5. The lighting node of claim 1, wherein the radio device comprises a radio transceiver.

6. The lighting node of claim 1, configured as a mesh network node.

7. The lighting node of claim 1, wherein the lamp comprises one or more light emitting diodes.

8. The lighting node of claim 1, configured for calibration of the generated illumination by the remote controller utilizing the color profile.

9. The lighting node of claim 1, configured for recalibration of the generated illumination by the remote controller utilizing the color profile stored on the remote controller after the lighting node has decalibrated.

10. A lighting node comprising:

a lamp configured for generating illumination, wherein the generated illumination can only be adjusted remotely;

a radio device configured for radio communication;

a memory configured to store a group identifier for the lighting node; and

wherein the radio device is configured to couple to a first remote controller by transmitting the group identifier to the first remote controller;

wherein the radio device is configured to remotely receive a color profile from the first remote controller;

wherein the lamp is configured to perform a background automatic calibration that occurs automatically without user involvement while the lightning node is executing another command from the first remote controller initiated by a user; and

wherein the lamp is configured to perform the background automatic calibration by generating illumination to substantially match the received color profile to compensate for decalibration of the lamp overtime.

11. The lighting node of claim 10, wherein the radio device is for registering the group identifier to a second remote controller.

12. The lighting node of claim 10, wherein the radio device is for forwarding the color profile from the first remote controller at the lighting node to another lighting node.

13. The lighting node of claim 10, wherein the color profile is the color profile of another lighting node with the same group identifier as the lighting node.

14. The lighting node of claim 10, wherein the radio device is for receiving a command to execute an illumination pattern re-routed from the first remote controller.

15. The lighting node of claim 10, wherein the lamp is configured to modulate the illumination without changing a perceived state of the illumination prior to the modulation.

16. The lighting node of claim 10, wherein the radio device is for receiving a binary search command or a global search command to identify the lighting node to the first remote controller.

17. A method of operating a lighting node for remote color setting, the method comprising:

coupling the lighting node to a remote controller;

receiving a background calibration command from the remote control device, wherein the background calibration command is sent from the remote controller automatically without user involvement while the lightning node is engaged in another command from the remote controller initiated by a user, wherein the other command requires the user to orient the an optical sensor of the remote controller at a lamp of the lighting node;

providing illumination from the lighting node to the optical sensor in response to the other command, wherein the lighting node includes one or more light-emitting diodes;

receiving a sequence of color adjustment commands including a target color profile from a remote controller until the illumination from the lighting node matches the target color profile; and

adjusting at least one of the one or more light-emitting diodes in sequential steps, in response to each of the color adjustment commands.

18. The method of claim 17, further comprising:

communicating identification information of the lighting node to the remote controller via a node radio device configured for radio communication with the remote controller.

19. The method of claim 17, wherein the other command is a brightness adjustment command.

20. The method of claim 17, wherein performing the background automatic calibration includes performing the background automatic calibration when the remote controller is within a mesh network range of the lighting node.
