The high energy efficiency and narrowband emission of LED light sources make lighting technology of great value in life science applications.

By using LED lighting and utilizing the unique spectral requirements of poultry, pigs, cows, fish, or crustaceans, farmers can reduce stress and poultry mortality, regulate circadian rhythms, significantly increase the production of eggs, meat, and other protein sources, while significantly reducing energy use and other input costs.

The biggest advantage of LED is its ability to provide customizable and adjustable spectrum. The spectral sensitivity of animals is different from that of humans, and the spectral requirements are the same. By optimizing the spectrum, radiation, and modulation in the livestock shed, farmers can create a good lighting environment for their livestock, making them happy and promoting their growth, while minimizing energy and feed expenses.

Poultry is four colored. Like humans, poultry have a peak sensitivity to green at 550nm. But they are also highly sensitive to red, blue, and ultraviolet (UV) radiation. However, the most significant difference between humans and poultry may be the visual ability of poultry to sense ultraviolet radiation (with a peak at 385nm).

Each color has a significant impact on the physiology of poultry. For example, green light can enhance the proliferation of skeletal muscle satellite cells and increase their growth rate in the early stages. Blue light increases growth at a later age by increasing plasma androgens. Narrowband blue light reduces movement and also reduces self destructive rates. Green and blue light can jointly promote the growth of muscle fibers. Overall, blue light has been proven to increase feed conversion rate by 4%, thereby reducing cost per pound by 3% and increasing overall live weight by 5%.

Red light can increase the growth rate and exercise volume of chickens at the beginning of the breeding period, thereby minimizing leg diseases. Red light can also reduce the feed consumption per egg production, while the produced eggs have no differences in size, weight, eggshell thickness, yolk and albumin weight. Overall, red lights have been proven to prolong peak production, with each hen producing 38 more eggs and potentially reducing consumption by 20%.
