Abstract
Disclosed is an illumination device. The device includes a light engine in an acoustic tile that introduces light into a plurality of optical fibers using an LED. In between the LED and the fiber ends, an LCD is used to modify the light introduced. To do this, the LCD is programmed to display petal-shaped sections which individually change in contrast to become more occluded and then more transparent. This creates an aesthetically pleasing effect resembling stars.
