Abstract

A lighting apparatus having a base member and a directional member are shown and described. The base member includes a first surface having a plurality of reflective elements extending therefrom. The base member also including a plurality of openings arranged in a pattern. Each openings is configured to receive a respective light source. The directional member has a portion of a reflective surface positioned relative to at least one opening to reflect light radiating from a lighting source disposed within the opening towards a portion of at least one of the reflective elements extending from the base member.

Claims (36)

1. A luminaire comprising:

a base of sheet material defining a first reflector having a first side extending from the base at a proximal edge of the first reflector first side, and a second side extending from the base at a proximal edge of the first reflector second side;

the first side of the first reflector and the second side of the first reflector meet at a distal edge of the first reflector;

the base defining a plurality of first openings adjacent to the proximal edge of the first reflector first side, the plurality of openings in register with a first row of LEDs;

the base of sheet material defining a second reflector having a first side extending from the base at a proximal edge of the second reflector first side, and a second side extending from the base at a proximal edge of the second reflector second side;

the first side of the second reflector and the second side of the second reflector meet at a distal edge of the second reflector;

the base defining a plurality of second openings adjacent to the proximal edge of the second reflector first side, the plurality of openings in register with a second row of LEDs; and

a directional member positioned over at least one first opening and one second opening to reflect light from the LEDs in register therewith.

2. The luminaire of claim 1 wherein the directional member resides in a portion of one or more of the first reflector or the second reflector.

3. The luminaire of claim 1 wherein the first reflector and the second reflector are formed integrally from the base of sheet material.

4. The luminaire of claim 1 wherein the first side of the first reflector defines an angle of about 0° to about −20° from perpendicular to the base.

5. The luminaire of claim 1 wherein the proximal edge of the first reflector first side is spaced from the proximal edge of the first reflector second side.

6. The luminaire of claim 1 the first reflector has a generally triangular cross-section.

7. The luminaire of claim 1 wherein the directional member extends substantially perpendicular to the first reflector and the second reflector.

8. The luminaire of claim 1 wherein the plurality of first openings and the plurality of second openings are arranged in parallel rows.

9. The luminaire of claim 1 wherein the sheet material is composed of sheet metal.

10. The luminaire of claim 1 wherein the directional member is composed of sheet metal.

11. The luminaire of claim 1 wherein the directional member defines an elongated V.

12. The luminaire of claim 1 , the base further defining a third plurality of openings in register with a third row of LEDs, the third plurality of openings not adjacent to any reflector; and the directional member also positioned over at least one third opening to reflect light from the LED in register therewith.

13. A luminaire comprising:

a base of sheet material defining a first reflector having a first side extending from the base at a proximal edge of the first reflector first side, and a second side extending from the base at a proximal edge of the first reflector second side;

the first side of the first reflector and the second side of the first reflector meet at a distal edge of the first reflector;

the base defining a plurality of first openings adjacent to the proximal edge of the first reflector first side, the plurality of openings in register with a first row of LEDs;

the base of sheet material defining a second reflector having a first side extending from the base at a proximal edge of the second reflector first side, and a second side extending from the base at a proximal edge of the second reflector second side;

the first side of the second reflector and the second side of the second reflector meet at a distal edge of the reflector;

the base defining a plurality of second openings adjacent to the proximal edge of the second reflector first side, the plurality of openings in register with a second row of LEDs; and

the base defining a third plurality of openings in register with a third row of LEDs, the third plurality of openings not adjacent to any reflector.

14. The luminaire of claim 13 wherein the first reflector and the second reflector are formed integrally from the base of sheet material.

15. The luminaire of claim 14 wherein the first side of the first reflector defines an angle of about 0° to about −20° from perpendicular to the base.

16. The luminaire of claim 13 wherein the proximal edge of the first reflector first side is spaced from the proximal edge of the first reflector second side.

17. The luminaire of claim 13 the first reflector has a generally triangular cross-section.

18. The luminaire of claim 13 wherein the directional member extends substantially perpendicular to the first reflector and the second reflector.

19. The luminaire of claim 13 wherein the plurality of first openings and the plurality of second openings are arranged in parallel rows.

20. The luminaire of claim 13 wherein the sheet material is composed of sheet metal.

21. The luminaire of claim 13 wherein the directional member is composed of sheet metal.

22. The luminaire of claim 13 wherein the directional member defines an elongated V.
