Poultry Lighting and the Spectrum

1. Spectrum knowledge
Spectrum (Spectrumm): After the complex light is split by the dispersion system (such as prism, grating), the dispersed monochromatic light is arranged in order according to the wavelength (or frequency). The full name is the optical spectrum. The spectrum shows the intensity information of the light waves of various wavelengths. Human research on the spectrum can be traced back to 1666. Newton decomposed the sunlight through the glass prism into various spectra from red light to purple light. He found that white light is composed of various colors of light. This is the earliest study of the spectrum. In recent years, with the rapid development of modern poultry farming, scale and intensive production have become the main trends. Scientific lighting is also increasingly valued.

2. Biological characteristics of the spectrum of breeding lamps
The eyes of poultry occupy one-third of the head and have very sharp vision. Therefore, the eyes are very sensitive to changes in light rays. In addition, light can penetrate the feathers of chicken skulls and directly act on the hypothalamus and pineal gland, which has a direct impact on the growth and development of chickens.
Research by relevant scientific research units has confirmed that red light can stimulate poultry activities, increase exercise and feed intake, promote sexual maturity and egg-laying period, reduce feed consumption per egg, and prolong the egg-laying period. Green light can promote the proliferation of skeletal muscle satellite cells, accelerate early growth rate, promote calcium absorption, increase eggshell thickness, and avoid soft-shell eggs. Blue light can lower blood pressure, calm chickens naturally, and promote individual growth by increasing plasma androgens: blue light photons can improve feed conversion rate and reduce unit weight cost. It can also promote muscle growth and testicular hormone secretion. From this, people have summarized the different needs of different types of chickens for light: Laying hen spectrum: 2700-3000K effectively promotes the growth of laying hens, increases egg production, and improves egg quality. Adding red light components can accelerate sexual maturity and increase egg production. Breeding chicken spectrum: 2700-3000K Adding red light components can promote egg production and egg quality and improve the quality of chicks. Accelerate sexual maturity and prolong the egg-laying period. Broiler spectrum: 5500-6000K Adequate blue light, additional green light and red light help broilers grow quickly, reduce chicken pecking, increase appetite and increase weight.

Sexual maturity and egg-laying period, reduce feed consumption per egg, and prolong egg-laying period.
Green light: can promote the proliferation of skeletal muscle satellite cells, accelerate early growth rate, and promote calcium absorption, increase eggshell thickness, and avoid soft-shell eggs. Blue light: can lower blood pressure, calm chickens naturally, and promote individual growth by increasing plasma androgens: blue light photons can improve feed conversion rate and reduce unit weight cost. It can also promote muscle growth and testicular hormone secretion.
1. Light intensity
Light intensity is a physical term that refers to the luminous flux of visible light received per unit area. Referred to as illuminance, it is usually measured and displayed by a illuminance meter in lux (LX or IX).
2. Light uniformity
The uniform distribution of light is crucial to poultry farming. Uneven light distribution will lead to uneven distribution of populations, clustering, and crowding and fighting due to competition for food and water. Long-term and severe uneven illumination will also lead to uneven growth of the same batch of poultry, affecting the marketing plan.
3. Light strobe Strobe refers to the fluctuation of the luminous flux of the electric light source at a certain frequency. Depends on the dimming mode and dimming depth. The human eye cannot distinguish flicker above 1001Hz, but the eyes of chickens are very sharp, and they can see flicker below 200Hz. Flicker can cause panic and fright to chickens, increase diseases, lead to stunted development, and cause chickens to peck and lose appetite. The dimming tube of Jidiao Optoelectronics not only meets the requirements of precise dimming and higher-precision duty cycle adjustment, but also can adjust the frequency of PN between 100-20KHz to ensure no flicker
