Illumination device, system and method for manually adjusting automated fading of color temperature changes to emulate exterior daylight
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.
1. An illumination device, comprising:
a plurality of light emitting diode (LED) chains;
a driver circuit coupled to the plurality of LED chains for automatically fading in a color temperature change from the LED chains depending on a time of day, wherein the automatically fading comprises fading in the color temperature change in a plurality of steps over a fixed amount of time without user actuation of a trigger upon the remote controller, and wherein the plurality of steps increase the color temperature an hour after sunrise;
a control module coupled to the driver circuit, said control module comprises:
a controller coupled to receive a change in intensity value from a remote controller that is remote from the controller and wirelessly or wired connected to the controller, and wherein the controller is coupled to receive the change in intensity value and, in response thereto, to produce a change in the color temperature output from the LED chains during a first time of day relative to a second time of day.
2. The illumination device as recited in claim 1 , wherein the time of day comprises daytime.
3. The illumination device as recited in claim 1 , wherein the time of day comprises nighttime.
4. The illumination device as recited in claim 1 , wherein the change in intensity value is applied by user actuation of a trigger on the remote controller.
5. The illumination device as recited in claim 1 , further comprises a dimmer coupled to AC mains, and wherein the change in intensity value is applied by user actuation of a trigger on the dimmer.
6. The illumination device as recited in claim 1 , wherein the change in intensity value corresponds to a fixed change in brightness applied to the LED chains to produce a greater change in color temperature output from the LED chains during the first time of day than during the second time of day.
7. The illumination device as recited in claim 1 , wherein the change in intensity value corresponds to a variable change in brightness applied to the LED chains to produce an equal change in color temperature output from the LED chains during the first time of day as that of the second time of day.
8. The illumination device as recited in claim 7 , wherein the variable change in brightness occurs as a function of the time of day.
9. An illumination device, comprising:
a plurality of light emitting diode (LED) chains;
a driver circuit coupled to the plurality of LED chains for automatically fading in a color temperature change from the LED chains depending on a time of day, wherein the automatically fading comprises fading in the color temperature change linearly over a fixed amount of time without user actuation of a trigger upon the remote controller, and wherein the linear change increases the color temperature an hour after sunrise;
a control module coupled to the driver circuit, said control module comprises:
a controller coupled to receive a change in intensity value from a remote controller that is remote from the controller and wirelessly or wired connected to the controller, and wherein the controller is coupled to receive the change in intensity value and, in response thereto, to produce a change in the color temperature output from the LED chains during a first time of day relative to a second time of day.
10. The illumination device as recited in claim 9 , wherein the time of day comprises daytime.
11. The illumination device as recited in claim 9 , wherein the time of day comprises nighttime.
12. The illumination device as recited in claim 9 , wherein the change in intensity value is applied by user actuation of a trigger on the remote controller.
13. The illumination device as recited in claim 9 , further comprises a dimmer coupled to AC mains, and wherein the change in intensity value is applied by user actuation of a trigger on the dimmer.
14. The illumination device as recited in claim 9 , wherein the change in intensity value corresponds to a fixed change in brightness applied to the LED chains to produce a greater change in color temperature output from the LED chains during the first time of day than during the second time of day.
15. The illumination device as recited in claim 9 , wherein the change in intensity value corresponds to a variable change in brightness applied to the LED chains to produce an equal change in color temperature output from the LED chains during the first time of day as that of the second time of day.
