Abstract

An intelligent light fixture is shown which allows for hands-free or automatic control of any desired combination of the color of the lighting beam, the focus position of the lighting beam, the movement of the lighting beam and projection of patterns created by the lighting beam. The intelligent light fixture is configured and mounted in such a way that all of the above can be accomplished from a single mounting position on top, or of within, the structure that holds the intelligent light fixture. The intelligent light fixture may be contained within a housing and said housing maybe mounted to a light pole.

Claims

1. A lighting fixture comprising:

a housing having a bottom surface and an aperture in the bottom surface;

a light source enclosed within the housing that directs light out through the aperture;

a translucent globe enclosing a bottom side of the housing;

a diffuser aligned below the aperture and within the globe, the diffuser having a solid volume defined by top, bottom, and side portions, wherein the top portion presents a single input surface for collecting the light for output to a number of output surfaces on an outward perimeter of the side portion; and

wherein the number of output surfaces define a number of recesses that re-direct the light laterally towards the globe.

2. The lighting fixture of claim 1 wherein the diffuser is positioned a distance below the bottom surface of the housing and wherein at least a portion of the recesses re-directs light into a portion of the globe extending across the distance.

3. The lighting fixture of claim 1 wherein an outer surface of the top portion is flat from one side surface to the other side surface.

4. The lighting fixture of claim 1 wherein an outer surface of the bottom portion is flat from one side surface to the other side surface.

5. The lighting fixture of claim 4 wherein at least a portion of the bottom portion forms an unlit area below the diffuser by preventing light from continuing to travel in the downward direction.

6. The lighting fixture of claim 1 wherein a cross-section of the diffuser is uniform throughout heightwise across a width defined from one side surface to a diametrically opposed side surface.

7. The lighting fixture of claim 1 wherein an outer surface area of the top portion is greater than an outer surface area of the bottom portion.

8. The lighting fixture of claim 1 wherein each of the laterally extending recesses is parallel to an adjacent laterally extending recess.

9. The lighting fixture of claim 1 wherein at least a portion of the recesses are prismatically shaped.

10. The lighting fixture of claim 1 wherein at least a portion of the recesses are angled.

11. The lighting fixture of claim 1 wherein the globe is a conically shaped enclosure having only one open end, the only open end being removably clipped to the housing.

12. The lighting fixture of claim 1 wherein the globe is tinted and the diffuser is clear.

13. The lighting fixture of claim 1 wherein the recesses are shaped to uniformly re-direct light towards an entire inner surface of the globe.

24. The lighting fixture of claim 1 wherein the entire input surface is perpendicular to an axis of the aperture.

14. A lighting fixture comprising:

a housing having a bottom opening;

a light source enclosed with the housing to direct light out through the bottom opening;

a translucent globe enclosing a bottom side of the housing;

a diffuser aligned below the bottom opening and within the globe, the diffuser having a solid volume defined by top, bottom, and side portions;

wherein an outer perimeter of the side portion is shaped to re-direct the downwardly directed light outwardly towards the globe; and

wherein the top and bottom portions are generally circular and the solid volume is at least equal to a volume defined by the following equation;

π

r²h

wherein r equals a lesser one of the radii of the top or bottom portions and h equals a height of the side portion.

15. The lighting fixture of claim 14 wherein the shape of the diffuser includes the top portion having a larger surface area than the bottom portion and the side portions sloping inwardly from the top portion to the bottom portion.

16. The lighting fixture of claim 15 wherein an entire outer surface of the diffuser is flat.

17. The lighting fixture of claim 15 wherein the top and bottom portions are flat and the side portion includes a number of recesses.

18. The lighting fixture of claim 17 wherein an entire outer surface of the top and bottom portions are parallel.

19. The lighting fixture of claim 18 wherein the entire outer surface of the top and bottom portions are parallel to the bottom surface of the housing.

20. The lighting fixture of claim 14 wherein the diffuser is positioned a distance below the housing and wherein at least a portion of the diffuser re-directs light into a portion of the globe extending across the distance.

21. The lighting fixture of claim 20 wherein the diffuser is shaped to re-direct light towards an entire inner surface of the globe.

22. The lighting fixture of claim 21 wherein the globe extends from the housing and around the top, bottom, and side portions.

23. The lighting fixture of claim 14 wherein a diameter of the aperture is smaller than a diameter of the diffuser and a diameter of the globe is greater than the diameter of the diffuser.
