Abstract

Techniques presented herein are directed to lighting management techniques supporting lighting functions of networked light fixtures. In accordance with one example, a light fixture in networked lighting system accepts a lighting request transmitted by a computing device. The light fixture determines whether the lighting request is a control message or a query message and performs one or more operations in response to the lighting request depending on whether the lighting request is a control message or a query message.

First claim

What is claimed is:

1 . A method comprising:
receiving a lighting request at a light fixture in a networked lighting system, wherein the light fixture comprises a local processor and a plurality of light emitters; extracting one or more light control settings from the lighting request; and adjusting lighting attributes of one or more of the plurality of light emitters based on the one or more light control settings.

2 . The method of claim 1 , wherein the lighting request is received from a device connected to the networked lighting system via a wireless connection with at least one light fixture in the networked lighting system.

3 . The method of claim 2 , wherein the wireless connection is a light communication connection.

4 . The method of claim 1 , wherein receiving the lighting request comprises:
wirelessly receiving, at the light fixture, the lighting request directly from a computing device.

5 . The method of claim 4 , wherein the lighting request is a first lighting request that is transparent to the light fixture, and wherein the method further comprises
forwarding the first lighting request to a switch; and receiving a second lighting request from the switch, wherein the second lighting request is configured to cause the light fixture to perform one or more operations.

6 . The method of claim 1 , wherein a computing device sends, via a network connection, the lighting request to a lighting management system of the networked lighting system, and wherein receiving the lighting request comprises:
receiving the lighting request from the lighting management system via the networked lighting system.

7 . The method of claim 1 , wherein the light fixture is a remote light fixture, and wherein the method further comprises:
wirelessly receiving, at a local light fixture, a first lighting request directly from a computing device, wherein the first lighting request is transparent to the local light fixture; forwarding the first lighting request to a switch; and receiving, at the remote light fixture, a second lighting request from the switch, wherein the second lighting request is configured to cause the remote light fixture to perform one or more operations.

8 . A method comprising:
receiving a lighting request at a light fixture in a networked lighting system, wherein the light fixture comprises a local processor and a plurality of light emitters; identifying, from the lighting request, one or more requested lighting attributes; generating a query response that includes the requested lighting attributes; and sending the query response to a computing device.

9 . The method of claim 1 , wherein the lighting request is received from a device connected to the networked lighting system via a wireless connection with at least one light fixture in the networked lighting system.

10 . The method of claim 9 , wherein the wireless connection is a light communication connection.

11 . The method of claim 8 , wherein receiving the lighting request comprises:
wirelessly receiving, at the light fixture, the lighting request directly from a computing device.

12 . The method of claim 11 , wherein the lighting request is a first lighting request that is transparent to the light fixture, and wherein the method further comprises:
forwarding the first lighting request to a switch; and receiving a second lighting request from the switch, wherein the second lighting request is configured to cause the light fixture to perform one or more operations.

13 . The method of claim 8 , wherein a computing device sends, via a network connection, the lighting request to a lighting management system of the networked lighting system, and wherein receiving the lighting request comprises:
receiving the lighting request from the lighting management system via the networked lighting system.

14 . The method of claim 8 , wherein the light fixture is a remote light fixture, and wherein the method further comprises:
wirelessly receiving, at a local light fixture, a first lighting request directly from a computing device, wherein the first lighting request is transparent to the local light fixture; forwarding the first lighting request to a switch; and receiving, at the remote light fixture, a second lighting request from the switch, wherein the second lighting request is configured to cause the remote light fixture to perform one or more operations.

15 . An apparatus comprising:
one or more network interface devices; a plurality of light emitters a memory; and a processor configured to:
receive a lighting request,
extract one or more light control settings from the lighting request, and
adjust lighting attributes of one or more of the plurality of light emitters based on the one or more light control settings.

16 . The apparatus of claim 15 , wherein the apparatus is part of a networking lighting system, and wherein the lighting request is received from a device connected to the networked lighting system via a wireless connection with at least one light fixture in the networked lighting system.

17 . The apparatus of claim 16 , wherein the wireless connection is a light communication connection.

18 . The apparatus of claim 15 , wherein at least one of the one or more network interface devices wirelessly receives the lighting request directly from a computing device.

19 . The apparatus of claim 18 , wherein the lighting request is a first lighting request that is transparent to the apparatus, and wherein the processor is configured to:
forward the first lighting request to a switch; and receive a second lighting request from the switch, wherein the second lighting request is configured to cause the apparatus to perform one or more operations in response to the second lighting request.

20 . The apparatus of claim 18 , wherein the apparatus is a local light fixture, and wherein the lighting request is transparent to the local light fixture such that processor is configured to forward the first lighting request to a remote light fixture via a switch.
