Abstract

A lighting fixture includes a light source, a housing coupled to the light source, communications circuitry, and control circuitry. The housing includes an opening through which light from the light source is provided. The control circuitry includes a memory storing instructions, which, when executed by the control circuitry cause the lighting fixture to adjust one or more light output parameters of the light source, and store fixture location information describing a location of the lighting fixture in response to receipt of the fixture location information from the communications circuitry. By storing fixture location information describing the location of the lighting fixture, the location of the lighting fixture may be used to send messages to lighting fixtures in the same location and/or retrieve data from lighting fixtures in the same location, which may be beneficial in many circumstances.

First claim

What is claimed is:

1. A lighting management system comprising:
communications circuitry;
processing circuitry; and
a memory storing instructions, which, when executed by the processing circuitry cause the lighting management system to:
receive user input including fixture location information describing a location of a lighting fixture;
associate the lighting fixture with the fixture location information; and
provide the fixture location information to the lighting fixture via the communications circuitry.

2. The lighting management system of claim 1 wherein the memory stores further instructions, which, when executed by the processing circuitry cause the lighting management system to instruct a display to provide a user interface showing a plurality of lighting fixtures within a space and a plurality of locations within the space.

3. The lighting management system of claim 2 wherein receiving the user input including the fixture location information describing the location of the lighting fixture comprises instructing the display and one or more user input peripherals to facilitate a drag-and-drop operation in which the lighting fixture is dragged onto one of the plurality of locations, such that the fixture location information corresponds to the location on which the lighting fixture was dropped.

4. The lighting management system of claim 1 wherein the memory stores further instructions, which, when executed by the processing circuitry cause the lighting management system to:
receive user input including instructions and recipient location information indicating one or more locations intended to receive the instructions;
provide a message via the communications circuitry, the message including the instructions and the recipient location information.

5. The lighting management system of claim 4 wherein the instructions include a command to one or more light output parameters of a light source in the lighting fixture.

6. The lighting management system of claim 5 wherein the one or more light output parameters include one or more of a light intensity, a color, and a color temperature.

7. The lighting management system of claim 4 wherein the instructions include a command to adjust one or more sensor operating parameters of one or more sensors in the lighting fixture.

8. The lighting management system of claim 7 wherein the one or more sensor operating parameters include one or more of an ambient light sensor sensitivity, an occupancy sensor sensitivity, and a sensor detection mode.

9. The lighting management system of claim 4 wherein the instructions include a command to adjust one or more operational parameters of the lighting fixture.

10. The lighting management system of claim 9 wherein the one or more operational parameters include one or more of an energy consumption operational parameter, a control group operational parameter, and an occupancy group operational parameter.

11. The lighting management system of claim 4 wherein the instructions include a request for information from the lighting fixture.

12. The lighting management system of claim 11 wherein the request for information is a request for data from one or more sensors in the lighting fixture.

13. The lighting management system of claim 1 wherein the memory stores further instructions, which, when executed by the processing circuitry cause the lighting management system to instruct a display to provide a user interface showing a spatial representation of the lighting fixture wherein the lighting fixture is displayed on a location on the display that is indicative of the location of the lighting fixture.

14. The lighting management system of claim 1 wherein the memory stores further instructions, which, when executed by the processing circuitry cause the lighting management system to:
receive a map of a space designating a plurality of locations within the space; and
associate the lighting fixture with one of the plurality of locations based on the fixture location information.

15. The lighting management system of claim 14 wherein the memory stores further instructions, which, when executed by the processing circuitry cause the lighting management system to present a user interface showing the map and the lighting fixture within the one of the plurality of locations in the space.

16. The lighting management system of claim 14 wherein:
the map characterizes the space in spatial coordinates;
each one of the plurality of locations within the space is associated with a set of the spatial coordinates; and
associating the lighting fixture with the one of the plurality of locations based on the fixture location information comprises associating the lighting fixture with the set of spatial coordinates associated with the one of the plurality of locations.

17. The lighting management system of claim 16 wherein the memory stores further instructions, which, when executed by the processing circuitry cause the lighting management system to present a user interface showing the map and the lighting fixture within the set of spatial coordinates associated with the one of the plurality of locations.

18. The lighting management system of claim 16 wherein the memory stores further instructions, which, when executed by the processing circuitry cause the lighting management system to present a user interface showing the map and data associated with one or more sensors in the lighting fixture in the set of spatial coordinates associated with the one of the plurality of locations.

19. The lighting management system of claim 14 wherein the memory stores further instructions, which, when executed by the processing circuitry cause the lighting management system to present a user interface showing data associated with one or more sensors in the lighting fixture in the one of the plurality of locations on the map.

20. The lighting management system of claim 14 wherein associating the lighting fixture with the one of the plurality of locations based on the fixture location information comprises comparing the fixture location information to location information associated with the one of the plurality of locations.

21. The lighting management system of claim 1 wherein the fixture location information is a human readable text string.
