Abstract: A lighting system includes a group of light emitting diode (LED) illumination devices, each of which includes a device driver. One or more sensors are configured to measure a characteristic of light received from the devices in an area of an environment that is illuminated by the devices. Alternatively, the sensors may be attached to the devices. A  controller detects when a value of the measured light characteristic received by a sensor deviates from a desired value. When this happens, the controller will cause the device drivers for each of the affected LED illumination devices to control LEDs in each illumination device so that the desired color temperature of light will be received at the location of the sensor while maintaining a substantially constant illuminance level at the location. In another embodiment, a user interface allows a user to select a scene that corresponds to a requirement to direct light of a specified color temperature and illuminance level to a location. The controller will then cause the device drivers for each of the identified illumination devices to control their corresponding illumination device so that the specified color temperature and illuminance level of light will be received at the location. A system and method for calibrating such a system is also disclosed.
