Claims
- 1. A lighting fixture actuated by an infra-red sensing motion detector, the lighting fixture having a decorative fixture body and comprising:
- a motion detector housing disposed to form an integral part of said decorative fixture body, said housing having a convexo-convex shape and comprising a generally convex bottom portion and a generally convex top portion defining said convexo-convex shape;
- wherein said generally convex bottom portion has an azimuthally extending lens aperture formed therein, said lens aperture having at least a portion extending out of the vertical direction;
- an infra-red sensor responsive to infra-red radiation mounted within said housing in view of said lens aperture;
- a plastic lens member covering said lens aperture and formed to conform to the curvature of said generally convex bottom portion, said lens member having a plurality of Fresnel lenses formed thereon and disposed to direct infra-red radiation to said sensor;
- wherein said motion detector bottom portion includes a frusto-conical wall portion defining said azimuthally extending lens aperture and said lens member is conically shaped to conform to said frusto-conical wall portion; and
- wherein said motion detector housing is disposed such that no portion of said decorative fixture body obstructs the fields of view of said plurality of Fresnel lenses.
- 2. The apparatus of claim 1, further comprising:
- vertical indexing means for vertically indexing said infra-red sensor with respect to said lens member; and
- azimuthal indexing means for azimuthally indexing said lens member with respect to said infra-red sensor.
- 3. The apparatus of claim 2, further comprising:
- a printed circuit board within said motion detector housing, said infra-red sensor being mounted on said printed circuit board; and
- wherein said vertical indexing means comprises stop means engaging said printed circuit board for establishing the vertical position of said printed circuit board and infra-red sensor.
- 4. The apparatus of claim 3, further comprising:
- a lens frame member having a second azimuthally extending lens aperture aligned with the lens aperture in said bottom portion; and
- wherein said azimuthal indexing means comprises a first index member on said lens frame member and a second index member on said lens member mating with said first index member for establishing the azimuthal position of said lens member.
- 5. The apparatus of claim 4 wherein said lens frame member and the bottom portion of said motion detector housing are indexed together.
- 6. The apparatus of claim 1, further comprising:
- a blocking member; and
- at least two infra-red sensors disposed within said bottom portion bilaterally with respect to said blocking member to receive infra-red radiation emanating from opposite sides of said blocking member whereby radiation emanating from one side of said blocking member is prevented from illuminating a sensor on the opposite side of said blocking member.
