Abstract

The present invention relates generally to a light emitting diode lighting fixture. In one embodiment, the light fixture includes an extrusion, a plurality of light emitting diodes (LEDs) and a lens coupled to the extrusion. The plurality of LEDs has a uniform spacing between each one of the plurality of LEDs along the extrusion.

Claims (33)

1. A light fixture, comprising:

an extrusion;

a plurality of light emitting diodes (LEDs) having a uniform spacing between each one of said plurality of LEDs along said extrusion;

a lens coupled to said extrusion; and

one or more mounting holes, wherein each one of the one or more mounting holes travels through said lens and said extrusion as a single hole.

2. The light fixture of claim 1 , wherein said extrusion comprises a heat sink.

3. The light fixture of claim 2 , wherein a thickness of said heat sink is a function of said uniform spacing between each one of said plurality of LEDs along said extrusion.

4. The light fixture of claim 1 , wherein a height of said lens is larger than a height of said extrusion.

5. The light fixture of claim 1 , wherein said light fixture is coupled end-to-end with a second light fixture having a second plurality of LEDs.

6. The light fixture of claim 5 , wherein said uniform spacing of all LEDs is maintained across said light fixture and said second light fixture.

7. The light fixture of claim 1 , wherein said mounting holes are placed relative to said plurality of LEDs to prevent dark spots and maximize optical efficiency on a targeted illumination area.

8. The light fixture of claim 1 , wherein said mounting holes are placed relative to said plurality of LEDs to prevent glare from said plurality of LEDs.

9. The light fixture of claim 1 , wherein said uniform spacing comprises approximately between 100 millimeters (mm) to 500 mm.

10. The light fixture of claim 1 , wherein said lens comprises an optical grade material.

11. The light fixture of claim 1 , wherein a ratio of said height of said lens to said height of said extrusion is greater than 1.

12. The light fixture of claim 1 , wherein a combined height of said height of said lens plus said height of said extrusion is less than 1 inch (in).

13. The light fixture of claim 1 , wherein said lens comprises a mask along a linear edge.

14. The light fixture of claim 1 , wherein said lens comprises a pigment.

15. An end-to-end connector for coupling multiple light fixtures, comprising:

a spacer;

a first side coupled to said spacer for coupling to a first light fixture, said first side comprising:

a first one or more connecting pins coupled to said first side of said spacer; and

a first one or more alignment posts coupled to said first side of said spacer; and

a second side coupled to said spacer for coupling to a second light fixture, said second side comprising:

a second one or more connecting pins coupled to said first side of said spacer; and

a second one or more alignment posts coupled to said first side of said spacer,

wherein said end-to-end connector maintains said a uniform spacing between a last LED of said first light fixture coupled to said end-to-end connector and a first LED of said second light fixture also coupled to said end-to-end connector, wherein the uniform spacing is consistent with a spacing between a plurality of LEDs of the first light fixture and a plurality of LEDs of the second light fixture.

16. The end-to-end connector of claim 15 , wherein a width of said spacer is a function of a uniform spacing between a plurality of light emitting diodes (LEDs) of said first and second light fixture.

17. An end-to-end connector for coupling multiple light fixtures, comprising:

a first interface for coupling to a first light fixture;

a flexible cord coupled to said first interface; and

a second interface for coupling to a second light fixture, wherein said end-to-end connector aligns said first light fixture in a first row and said second light fixture in a second row in parallel.

18. The end-to-end connector of claim 17 , wherein said end-to-end connector vertically aligns each one of a plurality of light emitting diodes (LEDs) of said first light fixture and each one of a plurality of LEDs of said second light fixture.
