Abstract
A recessed light fixture adapted to be installed in a hole in a ceiling panel having an exposed lower face and an opposite upper face has a frame bearing on the front face and engaged upward through the hole in the panel and a reflector mounted in the frame generally above the panel. A screw extending along an axis transverse to the panel is axially fixed in the frame above the panel, rotatable about the axis, and has an external screwthread. A retaining pawl is pivotal on the screw above the panel between an outer position projecting outward past the frame and an inner position and is displaceable axially along the screw downward toward the panel and upward away from the panel. A spring engaged between the pawl and the screw couples the pawl to the screw and is positioned to permit the pawl to move axially only downwardly relative to the screw. A cam on the frame forces the pawl into the outer position on downward axial displacement toward the panel.
