Abstract

Technologies are described herein for an illumination device and a corresponding fixture device. The illumination device includes a luminary module for the emission of light and an identification circuit containing identifying data, while the fixture device includes a driver module for supplying power to the illumination device and a controller module. When the illumination device is connected to the fixture device, the controller module communicates with the identification circuit of the illumination device to retrieve the identifying data and causes the driver module to supply the appropriate power to the luminary module of the illumination device.
