Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
A pop-up landscape light, comprising: a housing; a light compartment in said housing having a frusto conical shape; an electric light in said light compartment; a reversible electric rotary stepping motor in said housing; control means for selectively actuating said stepping motor for a predetermined number of revolutions in opposite rotational directions; a telescopically extensible member secured to said light compartment; an elongated coil of flexible material having a free end extending through said telescopic extensible member; electrical wiring extending through said telescopic extensible member and operably connected for supplying electrical power to said electric light; and meshing bevel gears connecting said motor to selectively wind and unwind said coil to extend and retract said telescopic extensible member for extending and retracting said light compartment through said circular opening in said top end of said housing.
Claim 2
Dependent Claim
136 words
A pop-up landscape light, comprising: a housing; a light compartment in said housing having a frusto conical shape; an electric light in said light compartment; a reversible electric rotary stepping motor in said housing; control means for selectively actuating said stepping motor for a predetermined number of revolutions in opposite rotational directions; a telescopically extensible member secured to said light compartment; an elongated coil of flexible material having a free end extending through said telescopic extensible member; electrical wiring extending through said telescopic extensible member and operably connected for supplying electrical power to said electric light; and meshing bevel gears connecting said motor to selectively wind and unwind said coil to extend and retract said telescopic extensible member for extending and retracting said light compartment through said circular opening in said top end of said housing.
