Abstract

A lighting fixture for a poultry housing can generally include an elongated body and a transparent cover that is selectively coupled to the body and is configured to create an internal space with the body. A first light emitting diode (LED) can be disposed in the internal space and can be configured to emit a light having a first color. A second LED can be disposed in the internal space and be configured to emit a light having a second color that is distinct from the first color. A controller can be electrically connected to and independently control an output of the first and second LEDs.

Claims

1. A lighting fixture for a poultry housing, the lighting fixture comprising:

an elongated body;

a transparent cover that is selectively coupled to the body and is configured to create an internal space with the body;

a first light emitting diode (LED) disposed in the internal space and that emits a light having a first color; and

a second LED disposed in the internal space that emits a light having a second color that is distinct from the first color;

wherein an output of the first and second LEDs is configured to be independently controlled;

wherein each of the first and second LEDs are disposed on a printed circuit board; and

wherein a plurality of heat dissipating fins extend from the body and the body has a threaded bore that receives a coupling including a plurality of electrically conductive wires extending therefrom to engage into a female receiving portion of a wire harness that electrically connects the printed circuit board of each of the first and second LED'"'"'s with a controller upon threadably connecting the coupling and wire harness together.

2. The lighting fixture of claim 1, further comprising a driver disposed in the internal space that is configured to independently control the output of the first and second LEDs.

3. The lighting fixture of claim 1, further comprising a reflector disposed in the internal space and that is configured to reflect the emitted light from the first and second LEDs toward the transparent cover.

4. The lighting fixture of claim 3 wherein the reflector has a generally planar portion that surrounds a first recessed portion, wherein at least one of the first and second LEDs is arranged in the internal space at a location such that the emitted light is transmitted through the first recessed portion.

5. The lighting fixture of claim 4 wherein the first recessed portion is formed by first reflector walls that taper in a direction toward the at least one of the first and second LEDs.

6. The lighting fixture of claim 4, wherein the first and second LEDs are disposed on the same printed circuit board.

7. The lighting fixture of claim 6, further comprising a driver that is disposed on the same printed circuit board and that is configured to electrically communicate with the controller to control the first and second LEDs.

8. The lighting fixture of claim 6, further comprising a seal disposed between the body and the transparent cover that inhibits moisture from entering the internal space.

9. The lighting fixture of claim 4, further comprising a third LED disposed generally adjacent to the first and second LEDs and that transmits a light having a third color through the first recessed portion.

10. The lighting fixture of claim 9 wherein the third color is the same as the first color and wherein the first, second and third LEDs cooperate to form a first group of LEDs.

11. The lighting fixture of claim 10, further comprising a fourth, fifth and sixth LED disposed in the internal space that cooperate to form a second group of LEDs, each of the fourth, fifth and sixth LEDs emitting a light having either the first or second colors.

12. The lighting fixture of claim 11 wherein the reflector further includes a second recessed portion and wherein the second group of LEDs collectively transmit light through the second recessed portion, the second recessed portion formed by second reflector walls that taper in a direction toward the second group of LEDs.

13. The lighting fixture of claim 12 wherein the first color is one of blue or white and the second color is one of green or red.

14. A lighting fixture for a poultry housing, the lighting fixture comprising:

an elongated body;

a transparent cover that is selectively coupled to the body and is configured to create an internal space with the body;

a first light emitting diode (LED) disposed in the internal space and that emits a light having a first color;

a second LED disposed in the internal space that emits a light having a second color that is distinct from the first color; and

a reflector disposed in the internal space and that has first and second recessed portions formed by first and second reflective walls, respectively, wherein the first reflector walls taper in a direction toward the first LED and the second reflector walls taper in a direction toward the second LED, wherein the reflector is configured to reflect the emitted light from the first and second LEDs toward the transparent cover;

wherein an output of the first and second LEDs is configured to be independently controlled;

wherein first and second LEDs are disposed on a printed circuit board;

wherein the body has a threaded bore that receives a coupling connected with a wire harness that electrically connects the printed circuit board of each of the first and second LED'"'"'s with a controller; and

wherein a first elastomeric seal is provided between the coupling and the elongated body that is compressed by threadably engaging the threaded coupling to the body, and a second elastomeric seal is provided between the transparent cover and the elongated body that is compressed by threaded fasteners coupling the transparent cover to the body.

15. The lighting fixture of claim 14, further comprising:

a driver that is configured to electrically communicate with a controller to control the first and second LEDs.

16. The lighting fixture of claim 14 wherein the first LED comprises three first LEDs that cooperate to form a first group of LEDs that all transmit light through the first recessed portion and wherein the second LED comprises three second LEDs that cooperate to form a second group of LEDs that all transmit light through the second recessed portion, wherein the first group of LEDs transmit one of green or red light and the second group of LEDs transmit one of blue or white light.

17. The lighting fixture of claim 16, further comprising a plurality of lighting fixtures that are electrically connected through a connector assembly having a wire harness and wherein a threaded coupling connects each lighting fixture of the plurality of lighting fixtures with the wire harness.

18. A lighting fixture for a poultry housing, the lighting fixture comprising:

an elongated body having a centrally positioned connector fitting arranged thereon;

a transparent cover that is selectively coupled to the body and is configured to create an internal space with the body;

a first plurality of light emitting diodes (LEDs) disposed in the internal space and that all emit a green light;

a second plurality of LEDs disposed in the internal space that all emit a blue light, wherein the connector fitting is positioned between the first and second plurality of LEDs; and

a reflector disposed in the internal space and that has first and second recessed portions formed by first and second reflective walls, respectively, wherein the first reflector walls taper in a direction toward the first plurality of LEDs and the second reflector walls taper in a direction toward the second plurality of LEDs, wherein the reflector includes a generally planar portion surrounding a distal end of the first and second reflective walls, respectively, and wherein the reflector defines a complementary plurality of holes that are configured to at least partially accept the first and second plurality of LEDs and reflect the emitted light from the first and second plurality of LEDs toward the transparent cover;
