Abstract

A system for sensing luminaire properties and controlling luminaire performance independently of the location, distance or orientation of the sensors relative to the source luminaire device that is being sensed. Thus, the installer and the maintenance crew are freed from issues and activities associated with sensor installation.

Claims

1. A system for sensing luminaire properties and controlling a luminaire performance based on sensor readings of the luminaire, wherein the sensor readings are taken without regard to the location, distance or orientation of the sensor relative to the luminaire, comprising:

a dimming control configured to control the dimming of a luminaire;

at least one sensor configured to take a sensor reading of the luminaire;

a gateway configured to receive sensor readings from the at least one sensor, and to control operation of the dimming control in accordance with an expected luminaire lifetime prediction relationship; and

a cloud server configured to control operation of the gateway, wherein

the at least one sensor sends periodic sensor readings to the gateway, and

the gateway sends sensor readings to the cloud server when the sensor readings are outside of sensor ranges expected by the gateway, and

the cloud server compares the sensor readings received from the gateway to the expected luminaire lifetime prediction relationship to determine whether the at least one sensor needs to be recalibrated.

2. The system of claim 1, wherein the gateway continuously adjusts the dimming level of the luminaire over time based upon the luminaire lifetime prediction relationship generated by the cloud server.

3. The system of claim 2, wherein a new luminaire lifetime prediction relationship is generated for the gateway by the cloud server when the cloud server receives the sensor readings that are outside of the expected sensor ranges.

4. The system of claim 1, wherein the gateway continuously adjusts the luminaire over time to maintain a color temperature of the luminaire.

5. The system of claim 1, wherein the expected sensor ranges are continuously updated by the server.

6. The system of claim 1, wherein the identification of the luminaire is done in the server and not in the gateway or sensor.

7. The system of claim 1, wherein the cloud server recalibrates the at least one sensor when the cloud server determines that the luminaire has been replaced.

8. The system of claim 7, wherein the cloud server determines that the luminaire has been replaced by detecting an increase in brightness of the luminaire over a period of time.

9. The system of claim 1, wherein the cloud server recalibrates the at least one sensor when the cloud server determines that the at least one sensor has been moved with respect to the luminaire.

10. The system of claim 1, further comprising:

a power meter for measuring the power used by the luminaire, and for transmitting luminaire power measurements to the gateway.

11. The system of claim 10, wherein each of the measurements comprise:

(i) a baseline message set, and

(ii) an updates message set.

12. The system of claim 11, wherein the updates message is sent to the gateway at regular intervals and the baseline message is sent to the gateway at major status changes.

13. The system of claim 1, wherein the luminaire lifetime prediction relationship generated by the cloud server is generated by comparing a manufacturers'"'"' theoretical lumen degradation prediction graph to measurements taken by the at least one sensor.

14. A system for sensing properties of a device and controlling a performance of the device based on sensor readings of the device, wherein the sensor readings are taken without regard to the location, distance or orientation of the sensor relative to the device, comprising:

a controller configured to control operation of the device;

at least one sensor configured to take a sensor reading of the device;

a gateway configured to receive sensor readings from the at least one sensor, and to control operation of the controller in accordance with an expected lifetime prediction relationship; and

a cloud server configured to control operation of the gateway, wherein

the at least one sensor sends periodic sensor readings to the gateway, and

the gateway sends sensor readings to the cloud server when the sensor readings are outside of sensor ranges expected by the gateway, and

the cloud server compares the sensor readings received from the gateway to the expected lifetime prediction relationship to determine whether the at least one sensor needs to be recalibrated.

15. The system of claim 14, wherein the gateway continuously adjusts operation of the device over time based upon the lifetime prediction relationship generated by the cloud server.

16. The system of claim 14, wherein the cloud server recalibrates the at least one sensor when the cloud server determines that the device has been replaced or that the at least one sensor has been moved with respect to the device.

17. A system for sensing properties of a device and controlling a performance of the device based on sensor readings of the device, wherein the sensor readings are taken without regard to the location, distance or orientation of the sensor relative to the device, comprising:

a controller configured to control operation of the device;

a dimming control configured to control the dimming of a luminaire;

at least one sensor configured to take a sensor reading of the luminaire;

a gateway configured to receive sensor readings from the at least one sensor, and to control operation of the dimming control in accordance with an expected luminaire lifetime prediction relationship; and

a cloud server configured to control operation of the gateway, wherein

the at least one sensor sends periodic sensor readings to the gateway, and

the gateway sends sensor readings to the cloud server when the sensor readings are outside of sensor ranges expected by the gateway, and

the cloud server compares the sensor readings received from the gateway to the expected luminaire lifetime prediction relationship to determine whether the at least one sensor needs to be recalibrated.

18. The system of claim 17, wherein the cloud server recalibrates the at least one sensor when the cloud server detects an increase in brightness of the luminaire over a period of time.

19. The system of claim 17, wherein the cloud server recalibrates the at least one sensor when the cloud server determines that the at least one sensor has been moved with respect to the luminaire.

20. The system of claim 17, wherein the gateway continuously adjusts at least one of:

the dimming level of the luminaire over time based upon the luminaire lifetime prediction relationship generated by the cloud server; and

the luminaire over time to maintain a color temperature of the luminaire.
