Optimization of multi-spectral poultry lamp for different periods and comfortable light environment

Chicken and eggs are widely consumed food. It is of great significance to promote poultry production safely and efficiently by rational use of light technology. In this paper, the poultry lamp is optimized based on non-visual effect and health lighting, which has four spectra of hatching, growth, breeding, and Sun-like. The optimal LED combination is obtained through spectrum superposition principle, and the optical design is carried out. The combination of one kind of white LED and 26 kinds of monochrome LEDs is the best effect for the multi-spectral poultry lamp optimization. The spectrum reach ratio of the three kinds of poultry spectra reaches more than 90%. In the optical design, the multi-spectral poultry lamp adopts ring array and TIR lens to achieve light collimation and improve light efficiency, and realizes the three kinds of poultry spectra and the Sun-like spectrum by lighting different LEDs. The results suggest that the multi-spectral poultry lamp can give consideration to the light requirement of poultry farming during different periods and provide the comfortable light environment for breeder.
