Abstract

Techniques are disclosed for programming a luminaire with location information, referred to herein as commissioning. Location information may include relative location information (e.g., the position of the luminaire relative to a reference point) and/or absolute location information (e.g., global coordinates for the luminaire). A commissioned luminaire can be configured to emit its location information via light-based communication (LCom). In some cases, the luminaire can be commissioned manually, by hard coding the luminaire with its location either at the luminaire itself or using a device (e.g., a smartphone, tablet, or a dedicated luminaire commissioning device) to program the luminaire with location information. In some cases, the luminaire can be commissioned automatically. In some cases, the luminaire may be configured to provide visual, aural, or tactile feedback to indicate that the luminaire has not received location data or that the luminaire has been moved.

Claims

1. A luminaire comprising:

a communication module configured to receive commissioning device locations from a plurality of commissioning devices over time, wherein;

a first commissioning device location received from a first commissioning device in the plurality of commissioning devices is used to determine luminaire location information; and

subsequent commissioning device locations received from the plurality of commissioning devices are used to improve the accuracy of the luminaire location information;

at least one solid-state light source configured to output light; and

at least one modulator configured to modulate the light output to allow for emission of light-based communication (LCom) signals, wherein the signals allow the luminaire location information to be determined;

wherein the luminaire is configured to provide at least one of visual, aural, and tactile feedback to indicate that the luminaire has not received the first commissioning device location.

2. The luminaire of claim 1, wherein the commissioning device locations are determined based on at least one of:

a global positioning system;

a Wi-Fi-based positioning system;

LCom signals; and

an inertial navigation system configured to calculate the commissioning device locations using data from an accelerometer and a gyroscopic sensor.

3. The luminaire of claim 1, wherein the luminaire is further configured to provide at least one of visual, aural, and tactile feedback to indicate:

that the luminaire has been moved.

4. The luminaire of claim 1, wherein the feedback includes transitioning the light output between a maximum and minimum dimming value.

5. The luminaire of claim 1, wherein the luminaire is further configured to stop providing the feedback after receiving the first commissioning device location.

6. The luminaire of claim 1, further comprising memory configured to store information related to at least one of the following:

whether the luminaire has received the first commissioning device location; and

whether the luminaire has been moved.

7. The luminaire of claim 1, further comprising memory configured to store the luminaire location information.

8. The luminaire of claim 1, wherein the luminaire location information is automatically updated based on data from one or more luminaire-based sensors after the luminaire has been moved.

9. The luminaire of claim 1, wherein LCom signals are not emitted until the first commissioning device location has been received.

10. The luminaire of claim 1, wherein the first commissioning device location is received via infrared (IR).

11. A system comprising the luminaire of claim 1 and the plurality of commissioning devices.

12. A method of commissioning a luminaire with location information, the method comprising:

providing at least one of visual, aural, and tactile feedback to indicate that luminaire location information has not been stored;

receiving a first commissioning device location from a first commissioning device in a plurality of commissioning devices;

utilizing the first commissioning device location to determine the luminaire location information;

storing the luminaire location information;

receiving subsequent commissioning device locations from the plurality of commissioning devices; and

improving the accuracy of the luminaire location information based on the received subsequent commissioning device locations.

13. The method of claim 12, further comprising providing at least one of visual, aural, and tactile feedback to indicate:

that the luminaire has been moved.

14. The method of claim 12, wherein the luminaire location information is stored in memory of the luminaire.

15. The method of claim 12, wherein the luminaire location information is stored in cloud storage.

16. The method of claim 12, wherein the first commissioning device determines the commissioning device location based on at least one of:

a global positioning system;

a Wi-Fi-based positioning system;

light-based communication signals; and

an inertial navigation system configured to calculate the first commissioning device location using data from an accelerometer and a gyroscopic sensor.

17. The method of claim 12, wherein the luminaire comprises:

at least one solid-state light source configured to output light; and

at least one modulator configured to modulate the light output to allow for emission of light-based communication signals, wherein the signals allow the luminaire location information to be determined.

18. A non-transitory computer program product encoded with instructions that, when executed by one or more processors, causes a process to be carried out, the process comprising the method of claim 12.
