LED roadway luminaire
View Patent ↗The luminaire comprises a housing including at least one optical module. The optical module has a plurality of light emitting diodes disposed within a reflector. The reflector includes opposed curved longitudinal walls and opposed curved end walls.
1. A roadway luminaire comprising a housing including at least one optical module, the optical module being comprised of an elongated light source disposed within a reflector, the reflector comprised of opposed curved longitudinal walls and opposed curved end walls, said end walls being oriented inwardly 90° or less relative to a plane in which said light source resides.
2. The luminaire of claim 1 , including at least two optical modules.
3. The luminaire of claim 2 , wherein said at least two optical modules have differently shaped curved longitudinal walls.
4. The luminaire of claim 3 wherein said at least two optical modules have at least substantially equivalently shaped endwalls.
5. The luminaire of claim 1 wherein said light source comprises a plurality of LED's.
6. The luminaire of claim 2 , wherein said at least two optical modules have optical axis in opposite directions.
7. The luminaire of claim 1 , wherein at least one of said longitudinal walls includes a reflective clip element.
8. The luminaire of claim 7 , wherein said clip element is compression fit to an edge of said wall.
9. The luminaire of claim 7 , wherein said clip is supported by said luminaire housing.
10. The luminaire of claim 1 , where said opposed end walls are curved in each of a horizontal and a vertical direction.
11. The luminaire of claim 1 wherein said longitudinal walls are longer than said end walls.
12. The luminaire of claim 1 wherein at least one of said longitudinal walls is oriented inwardly 90° or less relative to said plane.
13. The luminaire of claim 1 wherein at least one of said longitudinal walls is oriented outwardly 90° or more relative to the plane in which said light source resides.
14. A roadway luminaire comprising a housing including an electronics module and at least optical module, the optical module is comprised of a printed circuit board (PCB) including a plurality of light emitting diodes and a reflector encompassing said printed circuit board, said light emitting diodes being disposed in at least three arrays, a first array disposed adjacent a first end of said PCB, a second array disposed adjacent a second end of said PCB, and a third array disposed between said first and second, said reflector having endwalls oriented inwardly 90° or less relative to a plane in which said printed circuit board resides and at least one longitudinal wall oriented outwardly greater than 90° relative to the plane in which said printed circuit board resides.
15. The luminaire of claim 14 wherein at least about 40% of said light emitted by said third array exits said housing as non-reflected light.
16. The luminaire of claim 15 , wherein at least 50% of the light emitted by said first and second arrays exits said housing as reflected light.
17. The luminaire of claim 16 , wherein between about 1% and about 25% of the light emitted by said first and second arrays exits said housing as non-reflected light.
18. The luminaire of claim 17 comprising at least two optical modules.
19. A luminaire comprised of a housing including at least one optical module, said optical module comprised of a plurality of light emitting diodes disposed within a reflector, said reflector having opposed curved sidewalls and opposed curved end walls, said curved sidewalls oriented at different angles from one another relative to a plane in which said light emitting diodes reside.
20. The luminaire of claim 19 wherein said end walls are curved both horizontally and vertically.
