Abstract

An illumination device, system and method are provided herein for emulating sunlight along a daytime or nighttime locus. Sunlight is emulated depending on the path length of the sun relative to a structure containing the illumination device and system. One or more illumination devices can be grouped together and perform the sunlight emulation along the locus by producing different color temperatures throughout the day by all illumination devices within that group producing the same color temperature changes throughout the day. Moreover, a particular advantage of the preferred embodiments is the ability to manually change at any time the emulated natural sunlight output from the one or more groups of illumination devices and advantageously change the color output more so at certain times than at other times by simply actuating a trigger on a dimmer associated with a virtual or physical keypad.

Claims (20)

1. An illumination system, comprising:

a plurality of light emitting diode (LED) illumination devices grouped into a plurality of groups among rooms of a structure, wherein a first group of the plurality of LED illumination devices is within a first room of the structure;

a driver circuit coupled to each of the plurality of LED illumination devices, wherein a first driver circuit is coupled to each one of the first group of the plurality of LED illumination devices for automatically changing a color temperature output from only the first group of the plurality of LED illumination devices as a function of a time of day, separate and apart from the other groups of the plurality of LED illumination devices;

a first control module coupled to the first driver circuit, wherein said first control module comprises:

a first controller coupled to receive a change in intensity value from a remote controller that is remote from the first controller and wirelessly or wired connected to the first controller, and wherein the first controller is coupled to receive a change in intensity value and, in response thereto, to produce a change in the color temperature output exclusive to only the first group of LED illumination devices during a first time of day relative to a second time of day.

2. The illumination system as recited in claim 1 , wherein the change in intensity value is applied by user actuation of a trigger on the remote controller.

3. The illumination system as recited in claim 1 , further comprising a dimmer and wherein the change in intensity value is applied by user actuation of a trigger on a dimmer.

4. The illumination system as recited in claim 1 , wherein the change in intensity value corresponds to a fixed change in brightness applied to only the first group of the plurality of LED illumination devices to produce a greater change in color temperature output from the first group of the plurality of LED illumination devices during a first time of day than during a second time of day.

5. The illumination system as recited in claim 1 , wherein the change in intensity value corresponds to a variable change in brightness applied to only the first group of the plurality of LED illumination devices to produce an equal change in color temperature output from the first group of the plurality of LED illumination devices during a first time of day as that of a second time of day.

6. The illumination system as recited in claim 5 , wherein the variable change in brightness occurs as a function of the time of day.

7. The illumination system as recited in claim 1 , wherein the time of day comprises only daytime.

8. The illumination system as recited in claim 1 , wherein the time of day comprises nighttime.

9. The illumination system as recited in claim 1 , wherein:

a second group of the plurality of LED illumination devices is within a second room of the structure; and

the illumination system further comprises:

a second driver circuit coupled to each one of the second group of the plurality of LED illumination devices for automatically changing a color temperature output from only the second group of the plurality of LED illumination devices as a function of the time of day, separate and apart from the first group of the plurality of LED illumination devices; and

a second control module coupled to the second driver circuit, wherein said second control module comprises:

a second controller coupled to receive a change in intensity value from a second remote controller that is remote from the second controller and wirelessly or wired connected to the second controller, and wherein the second controller is coupled to receive a change in intensity value and, in response thereto, to produce a change in the color temperature output exclusive to only the second group of LED illumination devices during a third time of day relative to a fourth time of day.

10. The illumination system as recited in claim 9 , wherein the remote controller and the second remote controller comprises a portable computer or phone.

11. The illumination system as recited in claim 9 , wherein the remote controller and the second remote controller comprises a keypad and a second keypad, respectively.
