Abstract

The present disclosure discloses a hybrid LED lighting method and system for chicken coops. For example, a closed or semi-open chicken coop is provided with the hybrid LED lightings including white LED beads and yellow LED beads in a mixing ratio of about 1:5 to about 5:1 in a regularly alternating manner. The average light intensity on the chicken cages'"'"' underside exposed to the light of the hybrid LED lighting is about 5 to about 30 Lux. The closed chicken coop is lit by a hybrid LED lighting every day during fattening period; the semi-open chicken coop is exposed to natural light in the daytime and lit by the hybrid LED lighting at night during fattening period. Implementation of the present disclosure improves growth of chickens, increases uniformity of chickens, and improves health and resistance to epidemic diseases.

Claims

1. A method for lighting a chicken coop, the method comprising:

arranging white beads and yellow beads in a predetermined alternating manner to form a plurality of hybrid LED lightings, an individual hybrid LED lighting of the plurality of hybrid LED lightings comprising one or more white beads and one or more yellow beads, the plurality of hybrid LED lightings mounted in a closed or semi-open chicken coop, a ratio of the one or more white beads and the one or more yellow beads in the individual hybrid LED lighting ranging from 0.2 to 5 is 0.2an average light intensity of the plurality of hybrid LED lightings on underside of chicken cages or a floor associated with the closed or semi-open chicken coop ranging from about 5 to about 30 Lux;

in response to a determination of a closed farming mode, exposing chickens to light of the plurality of hybrid LED lightings for about 10 to 20 hours per day during a fattening period in the closed or semi-open chicken coop; and

In response to a determination of a semi-open farming mode, exposing the chickens to natural light in a daytime and to the light of the plurality of hybrid LED lightings for about 4 to 10 hours at a night during the fattening period in the closed or semi-open chicken coop, wherein, after the chickens are fed for a predetermined time period, a weight gain of the chickens exposed to the plurality of hybrid LED lightings is greater than a weight gain of chickens exposed to a plurality of only white LED lightings or a plurality of only yellow LED lightings.

2. The method of claim 1, wherein the white beads of the plurality of hybrid LED lighting are associated with red and blue spectra, and the plurality of hybrid LED lightings are associated with red-blue-yellow combined spectrum.

3. The method of claim 1, wherein the white beads and yellow beads of the plurality of hybrid LED lighting are arranged in a regularly alternating manner into at least one of a ring, straight line, triangle, square, trapezoid or rectangle.

4. The method of claim 1, wherein a color temperature, a dominant wavelength and a peak wavelength of the white beads of the plurality of hybrid LED lighting are about 6172 K, 492.5 nm and 450.5 nm, respectively, and wherein a color temperature, a dominant wavelength and a peak wavelength of the yellow beads of the plurality of hybrid LED lighting are about 1831 K, 588.3 nm and 591.1 nm, respectively.

5. The method of claim 1, further comprising:

letting a window of the closed or semi-open chicken coop open such that the chickens are exposed to natural light from the window of the chicken coop, or

letting the chickens go outside in the daytime during the fattening period in the semi-open farming mode.

6. The method of claim 1, wherein the chickens were exposed to the light of the plurality of hybrid LED lightings from about 17:

00 to about 20;

00 at the night during the fattening period in the semi-open farming mode.

7. A hybrid LED lighting system comprising:

a plurality of windows arranged along two sides of a chicken coop comprising a plurality of chicken cages, an individual chicken cage placed about 0.5 to about 1 meter away from another individual chicken cage, the individual chicken cage being opposite to a window of the plurality of windows, a bottom of the individual chicken cage being about 0 to about 0.5 meter away from ground of the chicken coop;

a plurality of hybrid LED lightings, an individual hybrid LED light mounted about 0.5 to about 2 meter above a bottom of the individual chicken cage and parallel to length of the individual chicken cage, the individual hybrid LED lighting comprising white beads and yellow beads in a regularly alternating manner, a ratio of the white beads and the yellow beads in the plurality of hybrid LED lightings is 0.2, an average light intensity of the plurality of hybrid LED lightings on underside of chicken cages or a floor associated with the chicken coop ranging from about 5 to about 30 Lux.

8. The hybrid LED lighting system of claim 7, wherein the white beads and the yellow beads of the plurality of hybrid LED lighting are arranged in a regularly alternating manner into at least one of a ring, straight line, triangle, square, trapezoid or rectangle.

9. A hybrid LED lighting system comprising:

a plurality of windows of a chicken coop that are spaced along two sides of the chicken coop;

a plurality of hybrid LED lightings mounted about 1.5 to about 4 meters away from ground, the plurality of hybrid LED lightings spaced along a plurality of chicken cages of the chicken coop, the plurality of hybrid LED lightings comprising white beads and yellow beads in a regularly alternating manner, a ratio of the white beads and the yellow beads in the plurality of hybrid LED lightings is 0.2, an average light intensity of the plurality of hybrid LED lightings on underside of chicken cages or a floor associated with the chicken coop ranging from about 5 to about 30 Lux.

10. The hybrid LED lighting system of claim 9, wherein the white beads and yellow beads of the plurality of hybrid LED lighting are arranged in a regularly alternating manner into at least one of a ring, straight line, triangle, square, trapezoid or rectangle.
