  • High intensity lamp with improved air flow ventilation
    Patent number: 5091835
    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.
