Description

Green and blue two-color LED combination light for broiler chicken farming

technical field

Background technique

The light environment is one of the important factors affecting the productivity of broilers. It plays an important role in regulating the physiological functions of broilers, and has a greater impact on the health and production capacity of broilers. Modern chicken farms generally use artificial light sources to improve the production performance of broilers, and formulate light management procedures according to the chicken farm environment, equipment and technical characteristics of light sources. At present, the artificial light sources used in chicken farms are mainly incandescent lamps and fluorescent lamps. Their disadvantages are high energy consumption, low efficiency, high heat production, and insignificant improvement in production performance. The above disadvantages can be overcome by LED light sources. CN202160516 announced the patented technology of "an LED light source control system for turkey breeding", which has made a useful attempt in this regard. However, the key point of this technology is the intelligent control of light intensity and light time. The artificial light source used for meat turkeys is monochrome LED, that is, green LED, whether it is in the brooding period or the fattening period. Using a single green light LED to raise broilers from beginning to end cannot meet the different needs of broilers for light at different growth stages, thus failing to promote the growth of broilers to the greatest extent. the
