Abstract

This disclosure relates to lighting fixtures, such as suspended lighting fixtures. Devices according to the present disclosure provide lighting fixtures capable of emitting in one or more primary directions, while simultaneously emitting in a direction toward a mount surface, reducing undesirable areas of insufficient light and more efficiently illuminating a space. Lighting fixtures disclosed herein can achieve this increase in illumination efficiency in many ways, including utilizing various lighting element arrangements, such as dual-sided lighting elements, and various lens arrangements, such as lens shape affecting the direction of emitted light.

Claims

1. A lighting fixture, comprising:

an elongated body configured to receive at least one lighting element, wherein said body comprises a lens having at least one emission surface opposite a fixture mounting surface and at least one elongated support structure integral to said body to receive said at least one lighting element, wherein said body and said lens form a single integral component; and

a suspension mechanism arranged to connect said body to said fixture mounting surface;

wherein said fixture is arranged to direct at least some light emitted by said at least one lighting element received by said elongated body toward a plane adjacent and parallel to said fixture mounting surface, wherein at least some light emitted from said fixture passes through said plane.

2. The lighting fixture of claim 1, wherein said lens comprises one or more reflective portions.

3. The lighting fixture of claim 1, wherein said lens comprises one or more opaque portions.

4. The lighting fixture of claim 1, further comprising said at least one lighting element, wherein said at least one lighting element comprises one or more LEDs.

5. The lighting fixture of claim 4, wherein said one or more LEDs are in contact with a printed circuit board (“

PCB”

).

6. The lighting fixture of claim 1, wherein said lens comprises a shape having an extended lateral profile.

7. The lighting fixture of claim 1, wherein said lens further comprises extended winged portions.

8. The lighting fixture of claim 1, further comprising said at least one lighting element.

9. The lighting fixture of claim 8, wherein said lighting element comprises holes allowing light to be emitted in multiple directions.

10. The lighting fixture of claim 8, wherein said lighting element comprises LEDs mounted to at least two sides of said lighting element.

11. The lighting element of claim 10, wherein said lighting element comprises a double sided PCB.

12. The lighting fixture of claim 8, further comprising reverse mount LEDs.

13. The lighting fixture of claim 1, wherein said lens is connected to said body by a living hinge.

14. The lighting fixture of claim 1, wherein said body houses electronic components.

16. The lighting fixture of claim 1, wherein said lighting element comprises LEDs.

17. The lighting fixture of claim 16, wherein said lighting element comprises reverse mount LEDs.

18. The lighting fixture of claim 16, wherein said LEDs are mounted to at least two sides of said lighting element.

19. The lighting element of claim 18, wherein said lighting element comprises a double sided PCB.

15. A lighting fixture, comprising:

an elongated body, wherein said elongated body comprises a lens portion which is integral to said body;

a suspension mechanism arranged to connect said body to a mounting surface; and

at least one lighting element configured to direct at least some light emitted by said at least one lighting element toward a plane adjacent and parallel to said mounting surface, such that some of said directed light can exit said fixture and pass through said plane, wherein said at least one lighting element is received by at least one elongated support structure integral to said body.

20. The lighting fixture of claim 15, wherein said lighting element comprises holes allowing light to be emitted in multiple directions.

21. The lighting fixture of claim 15, wherein said lighting element comprises a separate power strip of LEDs.

22. The lighting fixture of claim 15, wherein said body houses electronic components.
