ABSTRACT:
A high intensity lamp is provided for use in studio and theatrical lighting applications and the like, wherein the lamp includes an improved ventilated lamp housing for enhanced convective air flow to dissipate generated heat energy. The lamp housing has a generally cylindrical shape with a high intensity lamp bulb supported therein and a forward open end. The lamp housing is constructed from a plurality of inner and outer rings assembled in a concentric and axially overlapping relation to define a sequence of radially and axially open flow paths of expanding cross-sectional size to induce an enhanced convective cooling air flow from the interior to the exterior of the lamp housing. In addition, a curved reflector and a forward lens associated with the high intensity lamp bulb are removably supported on peripheral spring clips within the lamp housing, wherein these spring clips retain the reflector and the lens in spaced relation with the lamp housing to define additional axial flow paths for additional housing air flow ventilation.
