Abstract

A lighting system includes a plurality of LED lights having at least two different color LED lights. A controller is coupled to the LED lights for independently controlling the intensity of sets of different color LED lights. A program stored on a storage device is operable on the controller to control the intensity of each of the different sets of different color LED lights to produce light representative of color and intensity changes of outdoor daylight conditions.

Claims

1. A lighting system comprising:

a plurality of light fixtures having at least two different color lights;

a controller coupled to the lights for independently controlling the intensity of different color lights; and

a program stored on a storage device and operable on the controller to control the intensity of each of the different color lights to produce light representative of color and intensity changes of outdoor daylight conditions, wherein the controller overrides an intensity value for a lights to ensure a minimum intensity of light is provided.

2. The system of claim 1 wherein the program comprises sets of data defining predetermined periods of intensity for each of the different colored lights.

3. The system of claim 2 wherein the sets of data correspond to measured color and intensity of a prior day of daylight.

4. The system of claim 1 wherein the lights comprise LEDs emitting light at approximately 300 OK.

5. The system of claim 1 wherein the lights comprises LEDs emitting light at approximately 700 OK.

6. The system of claim 1 wherein two different lights emit light of warm and cold light respectively.

7. The system of claim 1 and further comprising multiple arrays of lights formed with LEDs, wherein some of the lights emit warm light and the others emit cold light.

8. The system of claim 7 wherein each array of lights is controlled separately with either a delay from a first light being controlled, or executing different synchronized programs corresponding to data collected at distances corresponding to distances between the arrays.

9. The system of claim 1 wherein each light is controlled separately with either a delay from a first light being controlled, or executing different synchronized programs corresponding to data collected at distances corresponding to distances between the arrays to simulate a cloud passing by the sun.

10. The system of claim 1 wherein the program comprises multiple programs, each corresponding to a different day of actual outdoor daylight, and at least one of such multiple programs is executed during a day.

11. The system of claim 1 wherein the program is normalized to provide an intensity of light that varies between a predetermined minimum and a maximum intensity.

12. A method of lighting an indoor space, the method comprising:

obtaining a day program representative of actual measured light color and intensity from an outdoor location during a day;

executing the program to provide intensity controls to at least two different colored lights; and

controlling the lights to provide a color and intensity of lighting that varies during a time period corresponding to the measured light color and intensity, wherein intensity value for a lights is controlled to ensure a minimum intensity of light is provided.

13. The method of claim 12 wherein the lights are LED arrays.

14. The method of claim 13 wherein the program comprises sets of data defining predetermined periods of intensity for each set of colored LED arrays.

15. The method of claim 13 wherein one set of LED lights comprises LEDs emitting light at least approximately 300 OK, and another set of LED lights comprises LEDs emitting light at most approximately 700 OK.

16. The method of claim 13 wherein each array of LED lights is controlled separately with either a delay from a first LED being controlled, or executing different synchronized programs corresponding to data collected at distances corresponding to distances between the LED arrays.

17. The method of claim 12 and wherein the controller overrides a color value to ensure a minimum temperature of light is provided.

18. The method of claim 12 wherein the program comprises multiple programs, each corresponding to a different day of actual outdoor daylight, and at least one of such multiple programs is executed during a day.

19. The method of claim 12 wherein the program is normalized to provide an intensity of light that varies between a predetermined minimum and a maximum intensity.
