Abstract
A luminaire includes a single luminaire housing that includes thermally isolated light source and power control device compartments. At least one light source is disposed within the luminaire housing, and at least one power control device is disposed within a second, thermally isolated compartment. The light source and power control device compartments are separated by a chamber that includes a substantially nonconductive member, which prevents heat from the light source compartment from travelling to the power control device compartment. Thermally isolating the power control device from at least a portion of the heat generated by the light source allows the power control device to be disposed relatively close to the light source without becoming overheated and damaged. A hollow, threaded rod extends between and couples together the light source compartment and power control device compartment. Electric wires connecting the light source and power control device extends through the threaded rod, providing necessary electrical power in an aesthetically pleasing design.
