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.
