1. An illumination system for illuminating an area of an occupied space to be occupied by one or more occupants, comprising:
a control module including:
a first input responsive to a first multi-level illumination command designated as an illumination level command,
a second input responsive to a second multi-level illumination command designated as a biological illumination command,
a first driving output operative to drive a first area illumination element having a first selected illumination profile,
a second driving output operative to drive a second area illumination element having a second selected illumination profile, and
a controller that is:
responsive to different levels of the first multi-level illumination command designated as an illumination level command,
responsive to different levels of the second multi-level illumination command designated as a biological illumination command, and
operative to derive from the levels of the first multi-level illumination command and from the levels of the second multi-level illumination command a first control signal to drive the first output for the first area illumination element and a second control signal operative to drive the second output for the second area illumination element for each combination of levels from the first and second multi-level illumination commands to independently vary an illumination level and a biological attribute of the illumination of the occupied space in response to independent commands from the first and second multi-level illumination commands.
