Abstract

The present disclosure relates generally to a light emitting diode (LED) luminaire. In one embodiment, the LED luminaire includes a linearly extended enclosure having an interior volume, one or more sides and a light exiting portion along a length of the linearly extended enclosure, wherein the one or more sides each comprise an inside surface and an outside surface, wherein at least a portion of the linearly extended enclosure comprises an extruded optically clear plastic, one or more first LEDs mounted on the inside surface of the one or more sides of the linearly extended enclosure and a reflector coupled to the interior volume of the linearly extended enclosure, wherein the reflector redirects light from the one or more first LEDs.

Claims (33)

1. A light emitting diode (LED) luminaire, comprising:

a linearly extended non-metallic enclosure having an interior volume formed by a single extruded piece having one or more sides and a light exiting portion along a length of the linearly extended non-metallic enclosure, wherein the one or more sides each comprises an inside surface and an outside surface, wherein at least a portion of the linearly extended non-metallic enclosure comprises an optically clear plastic;

one or more first LEDs mounted directly on the inside surface of one of the one or more sides of the linearly extended non-metallic enclosure via an interface material; and

a reflector coupled to the interior volume of the linearly extended non-metallic enclosure, wherein the reflector redirects light from the one or more first LEDs, wherein the reflector is located between the one or more first LEDs and one or more second LEDs that are positioned on an opposing side of the linearly extended non-metallic enclosure relative to the one or more first LEDs, wherein the one or more sides of the linearly extended non-metallic enclosure enclose the one or more first LEDs, the reflector and the one or more second LEDs.

2. The LED luminaire of claim 1 , wherein a central light emitting axis of the one or more first LEDs is oriented at about 180° with respect to a central light emitting axis of the one or more second LEDs, wherein the 180° has a tolerance of +/−25°.

3. The LED luminaire of claim 1 , wherein the one or more first LEDs are positioned such that a central light emitting axis of the one or more first LEDs is at about 90° with respect to a vector that is normal to a ground and coming out of the ground.

4. The LED luminaire of claim 1 , wherein the linearly extended non-metallic enclosure comprises one or more slots, wherein the reflector comprises one or more legs having a tab, wherein the reflector is coupled to the linearly extended non-metallic enclosure by placing the tab into a respective one of the one or more slots.

5. The LED luminaire of claim 4 , wherein the one or more legs of the reflector are spring loaded.

6. The LED luminaire of claim 4 , wherein light emitted from the one or more first LEDs at an angle of −90° to +20° relative to a central light emitting axis of the one or more first LEDs is reflected off of the reflector.

7. The LED luminaire of claim 1 , wherein the linearly extended non-metallic enclosure comprises one or more flange sections.

8. The LED luminaire of claim 7 , wherein each one of the one or more flange sections includes one or more holes for mounting.

9. The LED luminaire of claim 1 , wherein a seal is formed between a continuous surface along a perimeter of the linearly extended non-metallic enclosure and a continuous surface along a perimeter of an end cap on each end of the linearly extended non-metallic enclosure.

10. The LED luminaire of claim 1 , wherein the interface material is disposed between the one or more first LEDs and the inside surface of the one or more sides of the linearly extended non-metallic enclosure.

11. The LED luminaire of claim 1 , further comprising:

a power supply coupled to an interior volume of the reflector to provide power to the one or more first LEDs.

12. The LED luminaire of claim 1 , further comprising:

a power supply coupled to an exterior side of the linearly extended non-metallic enclosure.

13. The LED luminaire of claim 1 , wherein the LED luminaire provides at least 1000 lumens of visible light.

14. The LED luminaire of claim 1 , wherein the length of the linearly extended non-metallic enclosure is at least 12 inches.

15. The LED luminaire of claim 1 , wherein the linearly extended non-metallic enclosure is extruded with optical features.

16. A light emitting diode (LED) luminaire for producing at least 1000 lumens of visible light, comprising:

a linearly extended non-metallic enclosure having an interior volume formed by a single extruded piece having one or more sides and a light exiting portion along a length of the linearly extended non-metallic enclosure, wherein the one or more sides each comprises an inside surface and an outside surface, wherein at least a portion of the linearly extended non-metallic enclosure comprises an optically clear plastic;

one or more first LEDs mounted directly on the inside surface of one of the one or more sides of the linearly extended non-metallic enclosure via an interface material; and

a reflector coupled to the interior volume of the linearly extended non-metallic enclosure, wherein the reflector redirects light from the one or more first LEDs, wherein the reflector is located between the one or more first LEDs and one or more second LEDs that are positioned on an opposing side of the linearly extended non-metallic enclosure relative to the one or more first LEDs, wherein the one or more sides of the linearly extended non-metallic enclosure enclose the one or more first LEDs, the reflector and the one or more second LEDs.

17. A method for producing a light emitting diode (LED) luminaire, comprising:

extruding a non-metallic material to form a linearly extended non-metallic enclosure that is a single extruded piece, wherein at least a portion of the non-metallic material is optically clear, wherein a cross-section of the linearly extended non-metallic enclosure does not change during the extruding, wherein the linearly extended non-metallic enclosure has an interior volume, one or more sides along a length of the linearly extended non-metallic enclosure, wherein one or more sides each comprises an inside surface and an outside surface;

cutting the linearly extended non-metallic enclosure after the extruding to a length of at least twelve inches to form a first open end and a second open end;

coupling one or more first LEDs directly to the inside surface of one of the one or more sides of the linearly extended non-metallic enclosure via an interface material;

coupling a reflector to the interior volume of the linearly extended non-metallic enclosure wherein the reflector is located between the one or more first LEDs and one or more second LEDs that are positioned on an opposing side of the linearly extended non-metallic enclosure relative to the one or more first LEDs, wherein the one or more sides of the linearly extended non-metallic enclosure enclose the one or more first LEDs, the reflector and the one or more second LEDs; and

sealing the first open end with a first end cap and the second open end with a second end cap.

18. The method of claim 17 , wherein the extruding further comprises:

forming one or more flanges; and

forming one or more slots on the inside surface of the one or more sides to hold the reflector.
