Abstract

A motion activated light fixture has a housing comprised of a canopy, a base formed integral with the canopy and at least one illumination source mounted on the housing. The housing has a centrally located mounting hole which enables the base and canopy to be rotated 360 degrees around the mounting hole prior to being mounted on a selected vertical or horizontal surface. The sensor component mounts on an outer surface of the housing and includes a lens plate in which plural lens segments are formed in a plurality of rows so as to provide a substantially wide angle of view of up to 180 degrees and which view can be variably positioned utilizing the referred to mounting hole configuration.

Claims

1. A light fixture activated by motion, comprising:

(a) a housing having;

(i) a base suitable for mounting said housing on either a vertical or horizontal surface;

(ii) a canopy integral with said base adapted for receiving and fixedly mounting within said canopy selected motion sensor light detection components associated with said fixture and being further adapted for receiving and fixedly mounting within an aperture formed in an outer surface of said canopy at least one other selected motion sensor lens related component associated with said fixture; and

(iii) a centrally located mounting hole enabling said housing including said base and canopy to be rotatably positioned 360°

around said mounting hole prior to being mounted in a selected rotated position on a selected said vertical or horizontal surface;

(b) a selected number of sockets mounted on and extending outwardly from said canopy for holding a corresponding number of illumination sources operatively associated with said fixture; and

(c) a selected number of fixedly positioned motion sensor components each comprising;

(i) a lens plate mounted within an aperture formed on an outer surface of said canopy and having a plurality of lens segments positioned thereon, said lens plate having a substantially wide angle of view up to about 180°

; and

(ii) detector means located within said canopy operatively associated with said lens plate.

2. The light fixture of claim 1, wherein said fixture has two said sockets for holding two said illumination sources.

3. The light fixture of claim 1, wherein said fixture has two said fixedly positioned motion sensor components.

4. The light fixture of claim 1, wherein said lens segments are positioned on said lens plate in a plurality of rows.

5. The light fixture of claim 4, wherein said plurality of rows comprise a central row and four rows having curvature, with two of said rows having curvature being on each side of said central row.

6. The light fixture of claim 1, wherein said base is planar and said lens plate has a face the plane of which, when said lens plate is mounted on said canopy and is viewed from the side, is angled at substantially 45°

to plane of said base.

7. The light fixture of claim 1, wherein said lens segments each comprise a Fresnel lens.

8. The light fixture of claim 1, wherein said motion sensor component includes a lens plate holder mounted in said aperture and said lens plate is removeably mounted in said holder.

9. A light fixture as claimed in claim 1 wherein said fixture includes two adjustably positionable said sockets and two fixedly positioned said motion sensor components including two said lens plates, said canopy includes a central portion on opposite side surfaces of which said sockets are mounted and on end surfaces of which said lens plates are mounted wherein said fixture when utilizing the combined effects of said pair of lens plates provides a substantially 360°

angle of view.

10. A light fixture as claimed in claim 1 wherein said lens plate is curved.

11. A light fixture activated by motion, comprising:

(a) a housing having;

(i) a base suitable for mounting said housing on either a vertical or horizontal surface; and

(ii) a canopy integral with said base adapted for enclosing selected motion sensor components associated with said fixture and mounting on an outer surface of said canopy other selected said components;

(b) two sockets mounted on and extending outwardly from said canopy for holding corresponding two illumination sources associated with said fixture;

(c) two fixedly positioned motion sensors components each comprising;

(i) a lens plate mounted within an aperture formed on an outer surface of said canopy and having a plurality of lens segments positioned thereon, said lens plate having a substantially wide angle of view up to about 180°

; and

(ii) detector means located within said canopy operatively associated with said lens plate; and

(d) said canopy includes a central portion on opposite side surfaces of which said sockets are mounted and on end surfaces of which said lens plates are mounted wherein said fixture when utilizing the combined of effects of said pair of lens plates provides a substantially 360°

angle of view.

12. A light fixture as claimed in claim 11 wherein said housing comprises a centrally located mounting hole enabling said housing including said base and canopy to be rotatably positioned 360°

around said mounting hole prior to being mounted in a selected rotated position on a selected said vertical or horizontal surface.

13. A light fixture as claimed in claim 11 wherein each said lens plate is curved.
