  • Patent number: 10772303
    Abstract: The invention relates to eye-friendly green-blue mixed LED lighting methods and systems for chicken houses. In a chicken house, an evenly-distributed cyan light environment may be created for rearing broiler chickens. The chicken house may include mixed LED lamps associated with the cyan light environment, and the mixed LED lamp may be formed by combining green LED beads and blue LED beads on a lighting fixture with a mixing proportion of from about 0.2 to about 5. The mixed LED lamps may be used for about 24-hour lighting in the first three days of the breeding period. From the fourth day of the breeding period, the daily lighting duration may be progressively decreased by about one hour every day. The mixed LED lamps may be evenly arranged in the chicken house to form a square array.

  • Patent number: 9578858
    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.
