Abstract
A lighting system includes a group of light emitting diode (LED) illumination devices. 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. A controller may cause the processor to identify a set of the illumination devices that correspond to the scene, and to generate commands to cause the device drivers for each of the identified illumination devices to control its 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.
