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.
