Abstract
A luminaire having an electronically adjustable light beam distribution to provide upward illumination creating color gradients on a ceiling. The color gradients may be in patterns that mimic color gradients of a sky, including, for example, color gradients that mimic sunrise, sunset, sun at different times of day, a rainy day, clouds, the sun, moon, etc. The color gradients may change over time and/or may include one or more objects, e.g. clouds, the sun, moon, etc. and/or may move and/or change over time to create a dynamic sky on the ceiling. Multiple luminaires may be controlled by a system controller to produce coordinated color gradients across the light distribution areas of the multiple luminaires.
