Abstract

A handheld device having a light source, a communication interface, and control circuitry that is capable of interacting with a lighting fixture. The handheld device is capable of providing a light signal to the lighting fixture, receiving information from the lighting fixture, and selecting the lighting fixture as a selected lighting fixture based on the received information.

First claim

The invention claimed is:

1. A handheld device comprising:
a light source;
a communication interface; and
circuitry adapted to:
provide a light signal via the light source;
receive light level information from a plurality of lighting fixtures via the communication interface where the light level information for a given lighting fixture of the plurality of lighting fixtures includes an identifier for each of the plurality of lighting fixtures and relates to a light level at which the light signal was received at the given lighting fixture; and
select a selected lighting fixture of the plurality of lighting fixtures based on the light level information, wherein the light signal is visible light and the light level information that includes the identifier is received via radio frequency communication by the communication interface.

2. The handheld device of claim 1 wherein the circuitry is further configured to send via the communication interface an instruction that is intended to instruct the plurality of lighting fixtures to begin monitoring for the light signal.

3. The handheld device of claim 1 further comprising a user interface, wherein the circuitry is further configured to provide an indication via the user interface to a user once the selected lighting fixture is selected.

4. The handheld device of claim 1 further comprising a user interface, wherein the circuitry is further configured to receive an input from a user via the user interface, and in response to receiving the input, provide the light signal.

5. The handheld device of claim 1 wherein to select the selected lighting fixture, the circuitry is further configured to compare the light level for each of the plurality of lighting fixtures and select one of the plurality of lighting fixtures that is associated with a highest light level as the selected lighting fixture.

6. The handheld device of claim 1 wherein the identifier is an address.

7. The handheld device of claim 6 wherein upon selecting the selected lighting fixture, the circuitry is further configured to send instructions to the selected lighting fixture using the address for the selected lighting fixture.

8. The handheld device of claim 6 wherein upon selecting the selected lighting fixture, the circuitry is further configured to send information to the selected lighting fixture using the address for the selected lighting fixture.

9. The handheld device of claim 1 wherein the circuitry is further configured to instruct the selected lighting fixture to adjust its light output level to a level indicative of being selected.

10. The handheld device of claim 1 wherein the circuitry is further configured to:
successively select a plurality of selected lighting fixtures, including the selected lighting fixture, from the plurality of lighting fixtures;
create a group for the plurality of selected lighting fixtures; and
send group assignment information to each of the plurality of selected lighting fixtures, the group assignment information identifying the group to which each of the selected lighting fixtures belongs.

11. The handheld device of claim 10 wherein the circuitry is further configured to instruct each of the plurality of selected lighting fixtures to transition its light output level to a level indicative of being selected upon selection.

12. The handheld device of claim 11 wherein the circuitry is further configured to instruct each of the plurality of selected lighting fixtures to transition its light output level from the level indicative of being selected to a defined level after the group has been created.

13. The handheld device of claim 10 wherein the circuitry is further configured to select one of the plurality of selected lighting fixtures and remove the selected one of the plurality of selected lighting fixtures from the group.

14. The handheld device of claim 13 wherein the circuitry is further configured to send updated group assignment information to each of the group of the plurality of selected lighting fixtures, the updated group assignment information identifying a group to which each of the selected lighting fixtures belongs.

15. The handheld device of claim 10 wherein the circuitry is further configured to select a switch module, add the switch module to the group, and send the group assignment information to the switch module.

16. The handheld device of claim 1 wherein the circuitry is further configured to:
transmit via the communication interface an instruction to monitor for switch selection input;
receive an indication of switch selection from a switch module that received both the instruction and the switch selection input; and
select the switch module.

17. The handheld device of claim 16 wherein the identifier is an address.

18. The handheld device of claim 17 wherein upon selecting the switch module, the circuitry is further configured to send instructions to the switch module using the address.

19. The handheld device of claim 17 wherein upon selecting the switch module, the circuitry is further configured to send information to the switch module using the address.

20. A non-transitory computer readable medium comprising instructions for control circuitry of a handheld device, which has a light source and a communication interface, to:
provide a light signal via the light source;
receive light level information from a plurality of lighting fixtures via the communication interface where the light level information for a given lighting fixture of the plurality of lighting fixtures includes an identifier for each of the plurality of lighting fixtures and relates to a light level at which the light signal was received at the given lighting fixture; and
select a selected lighting fixture of the plurality of lighting fixtures based on the light level information, wherein the light signal is visible light and the light level information that includes the identifier is received via radio frequency communication by the communication interface.

21. The non-transitory computer readable medium of claim 20 wherein the instructions are further configured to cause the control circuitry to:
successively select a plurality of selected lighting fixtures, including the selected lighting fixture, from the plurality of lighting fixtures;
create a group for the plurality of selected lighting fixtures; and
send group assignment information to each of the plurality of selected lighting fixtures, the group assignment information identifying the group to which each of the selected lighting fixtures belongs.

22. The non-transitory computer readable medium of claim 21 wherein the instructions are further configured to cause the control circuitry to instruct each of the plurality of selected lighting fixtures to transition its light output level to a level indicative of being selected upon being selected.

23. The non-transitory computer readable medium of claim 22 wherein the instructions are further configured to cause the control circuitry to instruct each of the plurality of selected lighting fixtures to transition its light output level from the level indicative of being selected to a defined level after the group has been created.

24. The non-transitory computer readable medium of claim 21 wherein the instructions are further configured to cause the control circuitry to select one of the plurality of selected lighting fixtures and remove the selected one of the plural
