ABSTRACT:
The shutter drive mechanism and floodlight has an outer housing which surrounds the light fixture and also which protects the light fixture and a drive mechanism from the elements. Extending outward from the housing is a drive veil which supports the drive mechanism for raising and lowering a rigid shutter which covers the lens of the light fixture so that the light may be doused readily without turning off the lamp. The planar shutter moves horizontally or vertically within rails through a first and second slide, the shutter moveable by a drive arm which is affixed to a runner retained within a runner guide and driven by a screw drive. The shutter is actuatable between an opened and closed position such that the light fixture is adequately doused while the lamp remains on.
