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.

said light exit aperture positioned between said first portion of said master frame and said second portion of said master frame; and

a first extension of said first portion and a second extension of said first portion, a first and a second of said at least three LED boards mounted between said first and second extension of said first portion, said first and said second LED boards mounted above said light exit aperture;

a third of said at least three LED boards mounted on said second portion of said master frame adjacent said light exit aperture and substantially below said first and said second LED board.

2. 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.

3. 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.

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

5. The luminaire of claim 4, 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.

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

7. 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.

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

9. 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

a master frame coupled to said housing, said master frame including at least one pair of opposed mounting extensions on a first portion opposite said light exit aperture, at least two of said LED boards mounted and interposed between a single of said at least one pair of opposed mounting extensions;

a second portion of said master frame opposite said first portion and retaining at least one of said plurality of LED boards adjacent said light exit aperture;

wherein said master frame is retained within said housing, said light exit aperture extending substantially between said first portion and said second portion of said mounting frame.

10. The luminaire of claim 9, further comprising a plurality of heatsinks, each said heatsink in thermal connectivity with a single said LED board.

11. The luminaire of claim 10, wherein a plurality of said axes of said LED boards are at a non-parallel angle with respect to said first plane.

12. The luminaire of claim 10, further comprising a plurality of optical pieces, each said optical piece paired with a single said light emitting diode.

13. The luminaire of claim 12, wherein at least one said LED board is provided without any said optical pieces.

14. The luminaire of claim 10, wherein said axes corresponding to said LED boards are all at a common said non-parallel angle with respect to said first plane.

15. The luminaire of claim 9, wherein each said axis corresponding to each said LED board is at a twenty to forty degree angle with respect to said first plane.

16. The luminaire of claim 9, wherein said second direction is perpendicular to said first direction.
