Description

A supplementary light method and device combining natural light and LED in a chicken house

technical field

The invention relates to poultry houses, in particular to a light supplement method and device combining natural light and LEDs in a chicken house. the

Background technique

Chicken is a light-sensitive animal, and changes in light conditions will have a certain degree of impact on the physiology, behavior, and growth rate of chickens. The general situation is that people blindly use long-term supplementary light in order to obtain higher economic benefits. Blind supplementary light will not only fail to increase the growth rate of chickens, but will also affect the growth welfare and health of chickens, and reduce the quality of chickens. the

The traditional light supplement technology generally uses incandescent lamps and fluorescent lamps for supplementary light. These two light sources have high energy consumption, short service life and poor controllability. Compared with conventional light sources, LED light sources have high photoelectric conversion efficiency, high light utilization rate, strong controllability, long life, and high energy-saving effect. Using LED light sources to replace traditional incandescent lamps and fluorescent lamps for supplementary light has more advantages. big. the

At present, most breeding enterprises or farmers adopt the breeding mode of natural light in the daytime and artificial lighting in the evening. However, there is no scientific and unified guiding opinion on the light source, light intensity, and duration of the supplementary light. They have written their own documents, which leads to low breeding productivity. The waste of resources is serious. In view of the existence of these problems, it is imminent to study the combination of natural light and LED supplementary light technology in large-scale chicken houses. the
