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.
