Abstract
A lighting system includes a group of light emitting diode (LED) illumination devices. A controller may identify a set of the illumination devices that correspond to a zone, and to generate commands to cause the device drivers for each of the identified illumination devices to control its corresponding illumination device so that a specified color temperature, illuminance level, or both of light will be received at a location in the zone. A method for calibrating such a system is also disclosed. A user interface allows a user to select a scene after the calibration is complete.
