LED lighting is becoming more and more popular, especially in the application of agriculture. Researchers at the University of California at Davis have experimentally proven that using LED lights to raise chickens not only prevents bird flu, but also promotes the health of the birds and increases their value.
Traditionally, lighting has been in a supporting role in the chicken industry. Especially in the subtropical Taiwan region, there is plenty of sunshine, so that the general chicken farm can use windows and curtains to adjust the time of sunshine and indoor temperature. However, due to the open environment, it is easy to cause the spread of foreign bird flu. In Japan, Europe and the United States and other countries with cold belts, in order to improve the efficiency of temperature and humidity control, and the spread of foreign poultry diseases, closed chicken houses have become the mainstream of the chicken industry. And lighting has become an important key to controlling the growth of chickens.
In 2008, Taiwanese company Huangyou Technology and Japan's largest chicken equipment company, East Industries and Trade Co., Ltd., with the assistance of consultants, jointly developed a special LED bulb for raising chickens with ultrasonic wave-fixing lamps . It solves the functional requirements of stepless dimming, waterproof, dustproof and anti-corrosion required for chicken farm lighting. So far, about 200,000 have been successfully sold.
According to reports, LED dimming lighting systems (including bulbs and tubes) using DC voltage supply will be launched this year. In addition to the Japanese market, they are more active in selling to the leading countries of the chicken industry, the Netherlands, Germany and other EU countries. .
This system is different from the existing AC system, eliminating the common AC phase dimming, the disadvantage of 100% dimming and low dimming rate flicker. It is the most suitable pulse modulation (PWM) dimming method for LED light source, and it is successful. The one-time solution to the most common flashing frequency problem of LED lights. The phenomenon that the dynamic vision is superior to that of humans does not feel the phenomenon of flicker, which truly conforms to the EU's norms for animal welfare. In addition to the safety of direct current, the light source is in close contact with the chicken, and there is no danger of electric shock.
