Abstract: A double ended high intensity lamp holder of the type used in television and motion picture lighting applications is provided with an improved lamp holder for securely and safely supporting a double ended lamp. The improved fixture includes a pair of lamp holder assemblies each including a generally U-shaped lamp holder member with a spring clip thereon for quick and easy snap-fit reception of the opposite ends of a double ended lamp. The two lamp holder members are resiliently suspended by a spring mounting arrangement from a corresponding pair of support brackets, whereby the double ended lamp is resiliently mounted in a manner substantially isolating and protecting the lamp against damage due to thermal stress, physical shock, vibration, etc.

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.
