Abstract

A system and method for illuminating livestock within an agricultural dwelling. The system has a plurality of lighting assemblies that are electrically connected to a dimming device. The lighting assemblies are dimmed from a white color to predetermined wavelength to result in a predetermined behavior of the livestock. The predetermined wavelength and behavior includes a red wavelength that is undetected by the livestock thus resulting in the predetermined behavior of the livestock sleeping while workers can continue to work or function within the agricultural dwelling.

Claims

1. A method of illuminating livestock comprising:

providing a first plurality of lighting assemblies and a second plurality of lighting assemblies within a livestock housing facility;

illuminating the livestock with the first plurality of lighting assemblies and the second plurality of lighting assemblies by providing white light for a first predetermined period of time;

dimming the first plurality of lighting assemblies to provide a red light at a first predetermined wavelength between 620 nanometers (nm) and 780 nm for a second predetermined amount of time;

dimming the second plurality of lighting assemblies to provide a blue light at a second predetermined wavelength between 400 nm and 500 nm that attracts the livestock to food for a third predetermined amount of time; and

wherein a programmable dimming device is programmed to dim the first plurality of lighting assemblies from the white light to the first predetermined wavelength between 620 nm and 780 nm at a first time, and to dim the second plurality of lighting assemblies from the white light to the second predetermined wavelength between 400 nm and 500 nm at a second time.

2. The method of claim 1 wherein the livestock is swine and the livestock housing facility is a swine facility.

3. The method of claim 1 wherein the red light at the first predetermined wavelength between 620 nm and 780 nm is provided throughout a 24-hour period, including during the first predetermined amount of time.

4. The method of claim 3 wherein at least one of the plurality of lighting assemblies has a plurality of light emitting diodes that illuminate the livestock.

5. The method of claim 4 wherein the at least one of the plurality of lighting assemblies is waterproof to prevent water from reaching the plurality of light emitting diodes.

6. The method of claim 1 wherein the first and second predetermined amounts of time are equal.

7. The method of claim 4 wherein providing white light includes providing current to a first group of light emitting diodes arranged in series with a second group of light emitting diodes that emit the white light.

8. The method of claim 7 wherein providing red light includes providing current to a third group of light emitting diodes that emit the red light.

9. The method of claim 8, wherein the third group of light emitting diodes are connected in parallel to the first group of light emitting diodes and second group of light emitting diodes.

10. The method of claim 7 wherein dimming the plurality of lighting assemblies to provide only the red light includes dropping current flow to the first group of diodes.

11. The method of claim 10 wherein dimming the plurality of lighting assemblies to provide only the red light includes dropping current flow to the second group of diodes.
