Differential illumination to select egg laying sites
Differential illumination systems and methods selectively provide light having different spectrums in an aviary system for housing animals located within an enclosure, and in the enclosure. A first light source produces light with a first spectrum, and illuminates an internal volume of the aviary system. A second light source produces light with a second spectrum different from the first spectrum, and illuminates the enclosure outside of the aviary system. The first spectrum can have a higher red component than the second spectrum to encourage chicken to lay eggs inside of the aviary system, and the second spectrum can have a higher blue component than the first spectrum to discourage chicken from laying eggs outside of the aviary system.
1. A system comprising:
an aviary system located within an enclosure, wherein the aviary system includes an internal volume for housing animals, and wherein the animas can move between the aviary system and the enclosure;
a first light source producing light with a first spectrum, wherein the first light source illuminates at least part of the internal volume of the aviary system to cause a predetermined behavioral response in animals located in the internal volume; and
a second light source producing light with a second spectrum different from the first spectrum, wherein the second light source illuminates at least part of the enclosure outside of the aviary system to discourage a predetermined animal behavior in the enclosure outside of the aviary system;
wherein the first light source is a directional light source that concentrates illumination within the aviary system, and the second light source is a directional light source that avoids illumination from penetrating inside the aviary system;
wherein the first light source is directed away from an opening between the internal volume of the aviary system and the enclosure; and the second light source is directed away from an opening between the enclosure and the internal volume of the aviary system.
2. The system according to claim 1 , wherein the second light source includes light emitting diodes (LEDs).
3. The system according to claim 1 , wherein the first spectrum of the first light source has a higher red component than the second spectrum of the second light source.
4. The system according to claim 3 , wherein the first light source illuminates an area designed for the animals to lay eggs, roost, or feed.
5. The system according to claim 1 , wherein the second spectrum of the second light source has a higher blue component than the first spectrum of the first light source.
6. The system according to claim 5 , wherein the second light source illuminates an area in which laying eggs is discouraged.
7. The system according to claim 1 , wherein:
the second light source illuminates a floor area of the enclosure located substantially below or around the aviary system.
8. The system according to claim 1 , wherein the second light source illuminates an area of the enclosure located substantially above the aviary system.
