Abstract

A luminaire having a plurality of LED boards mounted within a housing is provided. Each LED board has at least one light emitting diode mounted thereon and an axis extending from a first end of the board to a second end of the board. Each LED board is adjusted about its respective axis to an orientation that is unique from at least two other LED boards.

Claims

1. A luminaire comprising:

a housing having a light exit aperture lying in a first plane;

at least three LED boards mounted within said housing and electrically connected to a power supply, each said LED board having a first end and a second end opposite said first end, an axis extending from said first end to said second end, and a surface extending from said first end to said second end, said surface having at least one light emitting diode thereon;

wherein each said LED board is adjusted about its respective said axis to an orientation that is unique from at least two other said LED boards; and

wherein a plurality of said axes of said LED boards are at a non-parallel angle with respect to said first plane.

2. The luminaire of claim 1, further comprising a plurality of heatsinks, each said heatsink in thermal connectivity with a single said LED board.

3. The luminaire of claim 1, wherein said axes corresponding to said LED boards are all at a common said non-parallel angle with respect to said first plane.

4. The luminaire of claim 3, further comprising a master frame coupled to said housing, wherein each said LED board is mounted to said master frame.

5. The luminaire of claim 1, wherein said axis corresponding to each said LED board is at a twenty to thirty degree said non-parallel angle with respect to said first plane.

6. The luminaire of claim 1, further comprising a plurality of optical pieces, each said optical piece paired with a single said light emitting diode.

7. The luminaire of claim 6, wherein at least one said optical piece includes a collimator lens having a first distribution angle and wherein at least one optical piece includes a collimator lens having a second distribution angle, said first distribution angle being distinct from said second distribution angle.

8. The luminaire of claim 1, wherein said axes of two or more said LED boards are non-parallel to one another.

9. The luminaire of claim 1, wherein said axes of at least two said LED boards lie in a second plane and said axis of at least one said LED board does not lie in said second plane.

10. The luminaire of claim 1, wherein each said axis lies in the center of a corresponding said LED board.

11. A luminaire comprising:

a housing having a light exit aperture lying in a first plane;

a plurality of LED boards mounted within said housing and electrically connected to a power supply, each said LED board having a first end and a second end opposite said first end, an axis extending from said first end to said second end, a surface extending from said first end to said second end, said surface having a plurality of light emitting diodes thereon;

wherein each said LED board is fixedly adjusted about its respective said axis to an orientation that is unique from at least two other said LED boards; and

wherein said axis of at least one said LED board extends in a first direction and said axis of at least one said LED board extends in a second direction, said second direction being non-parallel to said first direction.

12. The luminaire of claim 11, further comprising a plurality of heatsinks, each said heatsink in thermal connectivity with a single said LED board.

13. The luminaire of claim 12, wherein a plurality of said axes of said LED boards are at a non-parallel angle with respect to said first plane.

14. The luminaire of claim 12, further comprising a plurality of optical pieces, each said optical piece paired with a single said light emitting diode.

15. The luminaire of claim 14, wherein at least one said LED board is provided without any said optical pieces.

16. The luminaire of claim 12, wherein said axes corresponding to said LED boards are all at a common said non-parallel angle with respect to said first plane.

17. The luminaire of claim 11, wherein each said axis corresponding to each said LED board is at a twenty to forty degree angle with respect to said first plane.

18. The luminaire of claim 11, wherein said second direction is perpendicular to said first direction.

19. The luminaire of claim 11, wherein each said LED board is fixedly adjusted about its respective said axis to an orientation that is unique from any other said LED board.

20. The luminaire of claim 11, wherein at least three LED boards are provided and wherein said axes of at least two said LED boards lie in a second plane and said axis of at least one said LED board does not lie in said second plane.

21. A luminaire comprising:

a housing having a downlight aperture;

a master frame coupled to said housing and located within said housing;

a plurality of LED boards mounted to said master frame and electrically connected to a power supply, each said LED board having a first end and a second end opposite said first end, an axis extending from said first end to said second end, a first surface and a second surface extending from said first end to said second end, said first surface having at least one light emitting diode thereon, each said second surface having a heatsink coupled thereto;

wherein each said LED board is adjustable about its respective said axis to an orientation that is unique from at least two other said LED boards; and

wherein a plurality of said axes of said LED boards are at a non-parallel angle with respect to said light exit aperture.

22. The luminaire of claim 21, wherein said axes of said LED boards are all at a common said non-parallel angle with respect to said light exit aperture.

23. The luminaire of claim 21, wherein each said LED board is adjusted about its respective said axis to an orientation that is unique from any other said LED board.

24. The luminaire of claim 21, wherein said master frame has a first portion coupled to said first end of each said LED board and a second portion coupled to said second end of each said LED board.

25. The luminaire of claim 21, further comprising a plurality of optical pieces, each said optical piece paired with a single said light emitting diode.

26. The luminaire of claim 25, wherein at least one said optical piece includes a collimator lens having a first distribution angle and wherein at least one optical piece includes a collimator lens having a second distribution angle, said first distribution angle being distinct from said second distribution angle.

27. The luminaire of claim 26, wherein at least one said optical piece includes a collimator lens having a third distribution angle, said third distribution angle being distinct from said first distribution angle and said second distribution angle.
