Abstract

The present disclosure sets forth a motion sensing outdoor security light with the flexibility of being mounted to either a wall structure or to an eave or ceiling structure. An adjustable spherical motion sensor housing may be provided with the rotationally adjustable outdoor security light, allowing easy adjustment of motion detection ranges under different mounting schemes without comprising the aesthetic design of the light. The adjustable spherical motion sensor housing may also provide an enlarged horizontal field of view for better performance.

First claim

What is claimed is:

1. A spherical motion sensor housing mounted on an outdoor security light canopy, comprising:
a spherical shroud including a first shroud hemisphere and a second shroud hemisphere, the spherical shroud formed by joining the first shroud hemisphere with the second shroud hemisphere, wherein the first shroud hemisphere has a lens opening, a first occluding portion, and a second occluding portion, the lens opening defined by a center opening portion, a first horizontal extent opening portion, and a second horizontal extent opening portion, the first occluding portion and the second occluding portion in opposing relationship within the lens opening and extending inwards towards each other;
a lens covering the lens opening of the spherical shroud;
a motion detection unit mounted within the spherical shroud, the motion detection unit having an optical field of view for motion detection through the lens, wherein the optical field of view for motion detection includes a horizontal field of view and a vertical field of view;
wherein the horizontal field of view of the motion detection unit is expanded by the first horizontal extent opening portion of the lens opening and by the second horizontal extent opening portion of the lens opening; and
wherein the vertical field of view of the motion detection unit is limited by the first occluding portion of the first shroud hemisphere and the second occluding portion of the first shroud hemisphere.

2. The spherical motion sensor housing of claim 1 , wherein each of the first occluding portion and the second occluding portion is a tab with a curved surface.

3. The spherical motion sensor housing of claim 1 , wherein the lens is a partial spherical arc.

4. The spherical motion sensor housing of claim 1 , wherein the motion detection unit includes at least one PIR sensor mounted within the spherical shroud.

5. The spherical motion sensor housing of claim 4 , wherein the at least one PIR sensor includes a first, second, and third PIR sensors mounted within the spherical shroud, and facing the center opening portion, the first horizontal extent opening portion, and the second horizontal extent opening portion respectively.

6. The spherical motion sensor housing of claim 5 , wherein the motion detection unit further includes a mounting surface, the first, second, and third PIR sensors mounted on the mounting surface by a mounting block, wherein the mounting block has a plurality of block surfaces for holding the first, second, and third PIR sensors.

7. The spherical motion sensor housing of claim 6 , wherein the mounting surface is mounted internally within the spherical shroud to a rear portion of the second shroud hemisphere.

8. The spherical motion sensor housing of claim 7 , wherein the mounting surface is a printed circuit board mounted within the spherical shroud and carries the mounting block with the first, second, and third PIR sensors on a first circuit board face thereof behind the lens.

9. The spherical motion sensor housing of claim 4 , wherein the lens is a segmented Fresnel lens comprising a plurality of sections, wherein each section is capable of independently focusing infrared radiation for the at least one PIR sensor.

10. The spherical motion sensor housing of claim 9 , wherein the lens is curved in a conical or convex shape.

11. The spherical motion sensor housing of claim 1 , wherein the first occluding portion and the second occluding portion provides the motion detection unit mounted within the spherical shroud with an effective vertical angular field of view of about 40 degrees or less.

12. The spherical motion sensor housing of claim 1 , wherein the lens opening defined by the center opening portion, the first horizontal extent opening portion, and the second horizontal extent opening portion provides the motion detection unit mounted within the spherical shroud with an effective horizontal angular field of view of about 240 degrees or more.

13. The spherical motion sensor housing of claim 1 , wherein the motion detection unit is mounted within the spherical shroud proximal to a rear portion of the spherical shroud and distal from the lens.

14. The spherical motion sensor housing of claim 1 , wherein the outdoor security light canopy retains a supporting cup and the spherical motion sensor housing is mounted on the outdoor security light canopy by the supporting cup, the spherical shroud having a first interfacing tab attached thereto, the supporting cup having a first gear rack mounted thereon, and the first gear rack includes a plurality of first interfacing notches configured to mate with the first interfacing tab to allow the first interfacing tab to move along the first gear rack and allow a first axis adjustment of the spherical motion sensor housing.

15. The spherical motion sensor housing of claim 14 , further comprising a second interfacing tab attached to the outdoor security light canopy, the supporting cup further including a second gear rack mounted thereon, the second gear rack including a plurality of second interfacing notches configured to mate with the second interfacing tab to allow the second interfacing tab to move along the second gear rack to allow a second axis adjustment of the spherical motion sensor housing.

16. The spherical motion sensor housing of claim 15 , wherein the supporting cup further comprises:
at least one outwardly directed projection; and
at least one stop mounted within the outdoor security light canopy to limit the second axis adjustment of the spherical motion sensor housing by abutting the at least one outwardly directed projection against the at least one stop.

17. The spherical motion sensor housing of claim 14 , wherein the plurality of first interfacing notches of the first gear rack are provided on an arcuate/inclined surface in a linear configuration.

18. The spherical motion sensor housing of claim 15 , wherein the plurality of second interfacing notches of the second gear rack are provided on a planar surface.

19. The spherical motion sensor housing of claim 14 , wherein the first interfacing tab is attached to the second shroud hemisphere of the spherical shroud through a stem.

20. A spherical motion sensor housing mounted on an outdoor security light canopy, comprising:
a spherical shroud having a lens opening, a first occluding portion, and a second occluding portion, the lens opening defined by a center opening portion, a first horizontal extent opening portion, and a second horizontal extent opening portion, the first occluding portion and the second occluding portion in opposing relationship within the lens opening and extending inwards towards each other;
a lens covering the lens opening of the spherical shroud; and
a motion detection unit mounted within the spherical shroud, the motion detection unit having an optical field of view for motion detection through the lens, wherein the optical field of view for motion detection includes a horizontal field of view and a vertical field of view;
wherein the horizontal field of view of the motion detection unit is expanded by the first horizontal extent opening portion of the lens opening and by the second horizontal extent opening portion of the lens opening; and
wherein the vertical field of view of the motion detection unit is limited by the first occluding portion and the second occluding portion.

21. A spherical motion sensor housing adjustably mounted on an outdoor security light canopy, comprising:
a spherical shrou
