Abstract

A method for providing assistance in aiming of one or more illumination devices in an area may include, by a processor, receiving photometric data for an area, and using the photometric data to determine an aiming vector for the illumination device. the area may include the illumination device. the method may further include receiving, from an orientation sensor module of the illumination device, orientation data for the illumination device, and using the orientation data and the aiming vector to determine if there is an error in the aiming of the illumination device.

Claims

1. A method for providing assistance in aiming of one or more illumination devices in an area comprising, by a processor:

receiving photometric data for an area that comprises an illumination device;

using the photometric data to determine, for the illumination device, an aiming vector corresponding to the photometric data;

receiving, from an orientation sensor module of the illumination device, current orientation data for the illumination device;

analyzing the current orientation data and comparing the current orientation data to the aiming vector to determine if there is an error in the aiming of the illumination device; and

in response to making the determination that there is an error in the aiming of the illumination device, wirelessly transmitting instructions by the processor to present an error message on a user interface of an electronic device, wherein the error message comprises a set of instructions to accurately aim the illumination device,

wherein the photometric data comprises a desired measure of at least one light characteristic corresponding to light received from the illumination device at one or more reference points in the area when the illumination device is oriented in accordance with the aiming vector.

2. The method of claim 1, wherein the orientation data comprises one or more of the following:

orientation vectors, a linear acceleration, a yaw, a pitch, or a roll of the illumination device.

3. The method of claim 1, further comprising providing control signals to a controller associated with a driving means of the illumination device for correcting the error in the aiming of the illumination device, wherein the driving means control movement of at least one component of the illumination device.

4. The method of claim 1, wherein the orientation sensor module comprises one or more of the following:

an accelerometer, a gyroscope, an altimeter, or a magnetometer.

5. The method of claim 1, wherein using the current orientation data and the aiming vector to determine if there is an error in the aiming of the illumination device comprises determining whether there is a threshold difference between a current orientation of the illumination device and a desired orientation of the illumination device, wherein the desired orientation corresponds to the aiming vector.

6. The method of claim 1, further comprising determining a rate of change of orientation of the illumination device, wherein the rate of change of orientation is indicative of an event that resulted in the error in the aiming of the illumination device.

7. The method of claim 1, further comprising providing a control signal to a controller associated with a motor for correcting the error in the aiming of the illumination device, wherein the motor is configured to control orientation of the illumination device or a light emitting diode (LED) module included in the illumination device.

15. The method of claim 1, wherein the at least one light characteristic comprises at least one of the following:

intensity of light, amount of light, color of light, or flux of light.

8. A lighting control system, comprising:

an illumination device comprising one or more orientation sensors;

a processor of the illumination device configured to transmit wireless communication signals to an electronic device; and

a non-transitory computer-readable medium containing programming instructions that, when executed, will cause the processor of the illumination device to;

receive photometric data for an area;

use the photometric data to determine, for the illumination device, an aiming vector corresponding to the photometric data;

receive, from the one or more orientation sensors of the illumination device, current orientation data for the illumination device;

analyze the current orientation data and compare the current orientation data to the aiming vector to determine if there is an error in the aiming of the illumination device; and

in response to making the determination that there is an error in the aiming of the illumination device, wirelessly transmit instructions to present an error message on a user interface of the electronic device, wherein the error message comprises a set of instructions to accurately aim the illumination device,

wherein the photometric data comprises a desired measure of at least one light characteristic corresponding to light received from the illumination device at one or more reference points in the area when the illumination device is oriented in accordance with the aiming vector.

9. The system of claim 8, wherein the orientation data comprises one or more of the following:

orientation vectors, a linear acceleration, a yaw, a pitch, or a roll of the illumination device.

10. The system of claim 8, wherein:

the illumination device further comprises a controller associated with a driving means of the illumination device, wherein the driving means is configured to control movement of at least one component of the illumination device.

11. The system of claim 8, wherein the one or more orientation sensors comprise one or more of the following:

an accelerometer, a gyroscope, an altimeter, a global positioning system (GPS) or a magnetometer.

12. The system of claim 8, wherein the programming instructions that, when executed, will cause the processor to use the current orientation data and the aiming vector to determine if there is an error in the aiming of the illumination device comprise programming instructions to determine whether there is a threshold difference between a current orientation of the illumination device and a desired orientation of the illumination device, wherein the desired orientation corresponds to the aiming vector.

13. The system of claim 8, further comprising programming instructions that, when executed, will cause the processor to determine a rate of change of orientation of the illumination device, wherein the rate of change of orientation is indicative of an event that resulted in the error in the aiming of the illumination device.
