An embodiment of this invention relates to an intelligent lighting device
that can receive signals and change the illumination conditions as a
result of the received signals. The lighting device can change hue,
saturation, and brightness as a response to received signals. One example
of using such a lighting device is to display particular colors as a
response to certain events. Among others, embodiments may include vehicle
lighting systems, an information cube, a back lighting system for a
display panel, and an indicator of a condition of a package.
