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