With the domestic breeding hens scale, intensive degree of improvement, closed house large numbers, to the maximum extent possible to block the exchange discounted with homes outside environment, but also within the house "small environment" to create a higher requirements, in addition to the need to achieve the discounted temperature, humidity, ventilation volume reached more precise control, a set of evenly distributed, reasonable illumination, precise control of the artificial lighting system is also essential.

For now, almost all artificial light by lighting to achieve, we used lights generally have several: incandescent, halogen, energy saving lamps, cold cathode fluorescent lamp (CCFL), LED (light emitting diode).

In the current example of several LED lights inside, the lowest energy consumption, about 10% of incandescent, 25% of energy-saving lamps. Because it is solid package, and for the cold light source, which are devices in micro-and closed devices do not need to consider the heat problem. Compared with energy-saving lamps, fluorescent lamps, LED does not contain mercury, more environmentally friendly; for work in low-voltage DC power, the electromagnetic radiation, is an internationally recognized health lighting. Similar CCFL, LED light source because no filament, longer life, high-quality LED life of up to 50,000 to 100,000 hours.

By contrast the above table, we can see CCFL and LED color rendering and color temperature are better than traditional light sources, especially the higher discharge light electric power frequency, the smaller the stroboscopic effect, light is more stable, reducing eye fatigue chickens, guarantee normal growth and development.

Although the current market, CCFL and LED lights in the price will be higher than ordinary incandescent and energy-saving lamps, but its longer life and energy savings are enough to generate support from the initial purchase of the difference.

In the breeding process in different species of poultry, CCFL and LED can provide different options for heating and light color, if combining these two sources of low energy consumption, small size, to adapt to frequent light up, according to the different stages of aquaculture adjust brightness, etc. Features, which is precisely the access control system, which is undoubtedly provide a good choice for the modernization of laying hens closed sheds light control.
