ABSTRACT:
A pop-up landscape light has a cylindrical housing adapted for mounting below the surface of the ground in an outdoor environment. A light compartment is mounted for axial extension and retraction through an open top end of the housing to provide selective illumination. In a first embodiment of the present invention, a lead screw mechanism is utilized to extend and retract the light compartment from within the housing. In a second embodiment, a telescopic extensible member is connected to the light compartment and is actuated by winding or unwinding a coil of a flexible material driven by a motor through a bevel gear arrangement. In a third embodiment, a motorized swing arm mechanism is operative to rotate the light compartment through a predetermined angular increment, into and out of the housing, to provide selective illumination.
