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.

Abstract: An illumination system and method is provided for readily mapping a plurality of scenes along a dimcurve form a natural show for one or more groups of LED illumination devices. Mapping can be performed using a graphical user interface on a remote controller wirelessly linked to the illumination devices. A keypad is preferably configured for button control of changes to color temperature as a function of brightness along each of the various dimcurves for each of the various groups of illumination devices controlled by a corresponding keypad to allow momentary or persistent override and reprogram of the natural show. Modification to a scene further comprises modifications to scenes before and after the currently modified scene to provide a smoothing dimcurve modification. Global keypad can be used to control multiple zones arranged throughout a structure to switch between a natural show that emulates outdoor sunlight conditions to a panic show when an intruder is detected.

Abstract: A lighting control system and method is disclosed for not only controlling visual content loaded within a group set of illumination devices configured within a wireless network, but also for ensuring minimal control delay to those grouped devices. The lighting control system can include a lighting controller device that controls a plurality of lamps within a mesh network, not only to group those lamps but also to assign content to lamps within that group. The combination of a guaranteed groupcast to each of the group of lamps and an acknowledge back from those lamps that is aggregated over a single path achieves the improved lighting control system disclosed herein.

Abstract: A method and illumination device are provided for interference-resistant compensation in light emitting diode (LED) illumination devices. In one embodiment, the method includes bringing to a level insufficient to produce illumination the respective drive current of all except one of multiple emission LED elements for the duration of a first measurement interval and a later-occurring second measurement interval. The first and second measurement intervals are within respective first and second series of measurement intervals interspersed with periods of illumination, and the first and second series of measurement intervals are separated by respective first and second offsets from a timing reference. An embodiment of an illumination device includes multiple emission LED elements, one or more photodetectors, and a lamp control circuit, where the lamp control circuit is adapted to perform steps of the method.
