Abstract

Methods of tuning a luminaire having a first light source, a second light source, and a third light source, wherein each light source produces a different color of light including receiving a selected warmth, include the step of determining whether the light emitted by the first light source matches the amount of light needed from the first light source to match the selected warmth. It may be determined whether the first and second light sources are emitting sufficient light, and each may be adjusted to emit light having the selected warmth.

Claims

1. A method of tuning a luminaire having a first light source, a second light source, and a third light source, wherein each light source produces a different color of light, the method comprising the steps of:

operating each of first light source, the second light source, and the third light source;

receiving a selected warmth;

determining whether the light emitted by the first light source matches the amount of light needed from the first light source to match the selected warmth, wherein a determination that the light emitted by the first light source does not match the amount of light needed from the first light source results in operating the first light source to emit the amount of light needed from the first light source to match the selected warmth;

determining whether the light emitted by the second light source matches the amount of light needed from the second light source to match the selected warmth, wherein a determination that the light emitted by the second light source does not match the amount of light needed from the second light source results in operating the second light source to emit the amount of light needed from the second light source to match the selected warmth; and

determining whether the light emitted by the third light source matches the amount of light needed from the third light source to match the selected warmth, wherein a determination that the light emitted by the third light source does not match the amount of light needed from the third light source results in operating the third light source to emit the amount of light needed from the third light source to match the selected warmth.

2. A method according to claim 1 wherein the step of receiving a selected warmth comprises receiving a warmth from a user via a computerized device having a user interface, the method further comprising the steps of:

presenting to the user a confirmation message via the user interface; and

receiving a confirmation input from the user;

wherein an affirmative confirmation input results in continued operation of the first light source, the second light source, and the third light source; and

wherein a negative confirmation input results in a retuning operation of the luminaire.

3. A method according to claim 1 wherein the step of receiving a selected warmth comprises receiving a warmth from a user via a computerized device having a user interface, the method further comprising the step of receiving a value for an adjustment to the light emission of at least one of the first light source, the second light source, and the third light source from the user interface.

4. A method according to claim 1 wherein the first light source is a mint-white-light producing light source;

wherein the second light source is a blue light-producing light source; and

wherein the third light source is an amber light-producing light source.

5. A method according to claim 1 further comprising the steps of:

receiving a selected dominant color; and

adjusting the selected warmth to include the selected dominant color.

6. A method according to claim 5 wherein the step of adjusting the selected warmth to include the selected dominant color comprises increasing or decreasing emission of at least one of the first light source, the second light source, and the third light source.

7. A method according to claim 5 wherein the step of adjusting the selected warmth to accentuate the selected dominant color comprises increasing the light emitted by the one of the first light source, the second light source, and the third light source that is closest in color to the selected dominant color.

8. A method according to claim 5 wherein the computerized device comprises an image capture device, and wherein the step of receiving a selected dominant color comprises:

capturing an image of the environment by the image capture device; and

determining a dominant color from the captured image.

9. A method of tuning a luminaire having a first light source, a second light source, and a third light source using a computerized device having a user interface, the method comprising the steps of:

operating each of first light source, the second light source, and the third light source;

receiving a selected warmth via the user interface;

determining whether the light emitted by the first light source matches the amount of light needed from the first light source to match the selected warmth;

wherein a determination that the light emitted by the first light source does not match the amount of light needed from the first light source results in operating the first light source to emit the amount of light needed from the first light source;

determining whether the light emitted by the second light source matches the amount of light needed from the second light source to match the selected warmth;

wherein a determination that the light emitted by the second light source does not match the amount of light needed from the second light source results in operating the second light source to emit the amount of light needed from the second light source to match the selected warmth;

determining whether the light emitted by the third light source matches the amount of light needed from the third light source to match the selected warmth;

wherein a determination that the light emitted by the third light source does not match the amount of light needed from the third light source results in operating the third light source to emit the amount of light needed from the third light source;

receiving a selected dominant color; and

adjusting the selected warmth to include the selected dominant color.

10. A method according to claim 9 further comprising the step of receiving a value for an adjustment to the light emission of at least one of the first light source, the second light source, and the third light source from the user interface.

11. A method according to claim 9 wherein the step of adjusting the selected warmth to include the selected dominant color comprises increasing or decreasing the emission of at least one of the first light source, the second light source, and the third light source.

12. A method according to claim 9 wherein the step of adjusting the selected warmth to include the selected dominant color comprises increasing the light emitted by the one of the first light source, the second light source, and the third light source that is closest in color to the selected dominant color.

13. A method according to claim 9 wherein the computerized device comprises an image capture device, and wherein the step of receiving a selected dominant color comprises:

capturing an image of the environment by the image capture device; and

determining a dominant color from the captured image.

14. A tunable lighting system comprising:

a luminaire comprising;

a mint-white light-emitting diode (LED);

a first colored LED;

a second colored LED; and

a controller; and

a computerized device positioned in communication with the controller and configured to control the operation of each of the mint-white LED, the first colored LED, and the second colored LED,

wherein the computerized device comprises a user interface configured to receive a selected warmth; and

wherein the controller is programmable to operate the LEDs of the luminaire responsive to the selected warmth.

15. A tunable lighting system according to claim 14 wherein the computerized device further comprising an image capture device;

and wherein the computerized device is programmable to capture an image of an environment using the image capture device, determine a dominant color of the captured image, and cause the controller to operate the luminaire responsive to the dominant color.

16. A tunable lighting system according to claim 15 wherein the computerized device is a mobile phone.

17. A tunable lighting system according to claim 14 wherein the first colored LED is a blue LED;
