Abstract

A luminaire with various sensing and communication capabilities is provided. According to one aspect, the luminaire can include a housing, a light source disposed in the housing, a support element coupled to and extending downward from the housing, one or more communication modules disposed within the support element, and a motion sensor coupled to the support element. The one or more communication modules facilitate communication with a local controller disposed in the luminaire, a control system, and/or other luminaires. The motion sensor is configured to detect motion within a pre-determined range of the luminaire. The light source is configured to emit light responsive to the motion sensor detecting motion within the pre-determined range.

First claim

The invention claimed is:

1. A luminaire, comprising:
a housing;
a light source disposed in the housing;
a lens coupled to the housing and covering the light source; and
one or more communication modules configured to operate at various frequencies and disposed within a support element coupled to the housing, the support element disposed along a center axis of the luminaire and extending upward from an apex of the lens.

2. The luminaire of claim 1 , wherein the support element is coupled to and extends downward from the housing.

3. The luminaire of claim 1 , wherein the support element comprises a support post having a hollow, generally conical shape.

4. The luminaire of claim 1 , further comprising a motion sensor coupled to the support element, the motion sensor configured to detect motion within a pre-determined range of the luminaire, the light source configured to emit light responsive to the motion sensor detecting motion within the predetermined range.

5. The luminaire of claim 4 , further comprising a printed circuit board disposed in the support element along the central axis, the motion sensor being communicatively coupled to the printed circuit board.

6. The luminaire of claim 4 , wherein the motion sensor comprises a motion detecting lens, the motion detecting lens being exposed adjacent the apex of the lens.

7. The luminaire of claim 5 , wherein the motion sensor comprises a passive infrared sensor, the motion detecting lens having a conical shape.

8. The luminaire of claim 6 , wherein the motion sensor is wholly mounted within the lens.

9. The luminaire of claim 8 , wherein the lens does not include an aperture adjacent to the motion detecting lens.

10. The luminaire of claim 6 , further comprising an aperture in the apex of the lens, the motion detecting lens being disposed substantially within the aperture.

11. The luminaire of claim 1 , wherein the one or more communication modules comprise a first antenna and a second antenna each disposed within the support element, the first antenna configured to facilitate communication at a first frequency and the second antenna configured to facilitate communication at a second frequency different from the first frequency.

12. A luminaire, comprising:
a housing;
a light source disposed in the housing;
a support element coupled to and extending downward from the housing;
a lens coupled to the housing and covering the light source and the support element;
one or more communication modules disposed within the support element; and
a motion sensor coupled to the support element adjacent an apex of the lens, the motion sensor configured to detect motion within a pre-determined range of the luminaire, the light source configured to emit light responsive to the motion sensor detecting motion within the pre-determined range.

13. The luminaire of claim 12 , wherein the support element is disposed along a center axis of the luminaire extending upward from an apex of the lens.

14. The luminaire of claim 12 , wherein the support element comprises a support post having a hollow, generally conical shape.

15. The luminaire of claim 12 , wherein the motion sensor comprises a motion detecting lens, the motion detecting lens being disposed at the apex of the lens along a central axis of the luminaire.

16. The luminaire of claim 15 , further comprising an aperture in the apex of the lens, the motion detecting lens being disposed substantially within the aperture.

17. The luminaire of claim 12 , wherein the motion sensor comprises a passive infrared sensor, the motion detecting lens having a conical shape.

18. The luminaire of claim 12 , further comprising a printed circuit board disposed in the support element, the motion sensor being communicatively coupled to the printed circuit board.

19. The luminaire of claim 12 , wherein the one or more communication modules comprise a first antenna and a second antenna each disposed within the support element, the first antenna configured to facilitate communication at a first frequency and the second antenna configured to facilitate communication at a second frequency different from the first frequency.

20. The luminaire of claim 12 , wherein the motion sensor is wholly mounted within the lens.

21. The luminaire of claim 20 , wherein the lens does not include an aperture adjacent to the motion sensor.

22. A luminaire, comprising:
a housing;
a light source disposed in the housing;
a lens coupled to the housing and covering the light source;
a motion sensor disposed adjacent to an apex of the lens; and
one or more wireless modules disposed adjacent the motion sensor, the motion sensor configured to detect motion within a pre-determined distance from the luminaire, the light source configured to emit light responsive to the motion sensor detecting motion within the pre-determined distance.

23. The luminaire of claim 22 , wherein the motion sensor is disposed along a central axis of the luminaire.

24. The luminaire of claim 22 , further comprising a conical support post coupled to and extending downward from the housing, the conical support post being disposed along a central axis of the luminaire, the motion sensor being coupled to the support post.

25. The luminaire of claim 22 , wherein the motion sensor is wholly mounted within the lens.

26. The luminaire of claim 25 , wherein the lens does not include an aperture adjacent to the motion detecting lens.

27. The luminaire of claim 22 , further comprising an aperture in the apex of the lens, the motion detecting lens being disposed substantially within the aperture.
