Depth analysis: LED lamps how to make you eat delicious chicken

Some time ago a hubbub of frozen zombie meat incident, now think of it still lingering fear! Although it was finally proved that the freezing time was exaggerated, the freezing time was not the norm. Food safety really worrying!

LED can grow green and safe vegetables, if you don't want to eat chicken, LED have a way? The answer is yes! Magic LED allows you to eat delicious chicken chicken!

Don't laugh! Please call me chicken! Today, we talk about the Chinese experts chicken law, tomorrow, how to raise chickens in the United states.

Effects of illumination on the physiology of laying hens

The effect of light on the reproductive endocrine changes and the regulation process of poultry is very significant. Different light intensity and light time have a direct impact on the production performance of layers. The mechanism can be understood as follows: it is generally believed that there are two photoreceptors in poultry: the 1 retinal receptor, the eye, and the hypothalamus, the 2. Light stimulation of the optic nerve to hypothalamus; in addition, the light can also act on the pineal gland and hypothalamus. The hypothalamus stimulates the secretion of gonadotropin releasing hormone, which reaches the anterior pituitary via the hypophyseal portal system. The development of the follicle to produce estrogen, the hen oviduct development and maintain their skills, make the hen comb red, open toe and other sexual characteristics appear. Estrogen can promote the metabolism of calcium, is conducive to the formation of eggshell. Ovulation hormones cause ovulation.

Several light related factors affecting the production of laying hens

1, light intensity: generally use lux to mark, according to the different age of chicken, 20-30lux is commonly used in poultry breeding standards. Because of the number, type and location of the light source, the light intensity difference is very big. So, our experience is, according to the source, tested by computational scientific and professional illumination instrument, to determine the height of the light inside the house layout, distance.

2, light time: different growth stages, the requirements of the layers of light is not the same, and different kinds of chicken, the requirements of light is not the same. In this regard, there are already a lot of relevant standards for reference, here will not repeat.

3, color: people have three kinds of receptors, so the trichromatic vision, visible spectral wavelength together perceived by the human eye is 400 760nm between the different wavelengths of the electromagnetic waves, caused by the human eye to color the feeling is different, and the range of visible light waves with chicken eyes can discern the visible light range is not the same. Birds are four color visual animals. Four kinds of cones, they can let them see the red green blue and ultraviolet light. Different light and color perception, but also constitutes a layer of different feedback. In 1986, MarcO.North, an American scholar, compiled a chart in which he pointed out the effects of these colors on the performance and characteristics of poultry.

4, strobe: strobe is the depth of the light flux of the light source, the greater the fluctuation depth, the more serious the strobe, and the technical quality of the electric light source is directly related. The electronic rectifier is not good, the voltage fluctuation is not stable; the lamp tube is aging, the frequency of the power grid is unstable, which can cause the strobe of the lamp, and the stroboscopic effect is serious. The human eye is unable to distinguish the less obvious stroboscopic phenomenon, and the reliable data show that the chicken can see the stroboscopic phenomenon of different light sources, and this stroboscopic phenomenon can affect the behavior of chickens. Therefore, there is no stroboscopic, can be used as a criterion to judge whether a light source is healthy and harmless.

What is the use of artificial light reproduction

With the domestic farming scale and intensive enhancement, enclosed house appeared in large numbers, the maximum block inside and outside her exchange environment at the same time, also in the henhouse "small environment" to put forward higher requirements, in addition to the implementation of the indoor temperature and humidity, ventilation to control more accurate, a set of uniform and reasonable illumination, precise control of the artificial illumination system is also essential.

At present, artificial light is almost realized by lighting, we used lamps generally have several: incandescent lamps, halogen lamps, energy-saving lamps, cold cathode fluorescent lamp (CCFL), LED (light emitting diode).

Incandescent lamp

The working principle of incandescent lamp filament is electrically heated to incandescence, visible light emitted by thermal radiation, which has the advantages of low price, high versatility, fast startup, significant advantages of good color, the spectrum is continuous and uniform, with excellent color rendering. So incandescent lamp was widely used in livestock and poultry lighting in early stage.

But since the work of incandescent lamp filament temperature is very high, most of the energy in the form of infrared radiation is wasted, so the power conversion efficiency is very low, only about 2% of the electricity energy into light energy; at the same time because the filament temperature is high, the evaporation is also very fast, so life is greatly shortened, usually life in 1000 hours, but the light effect in about 12 per watt (Lm).

At present, in the world to promote energy-saving emission reduction, and actively respond to climate change, many countries have introduced the elimination of incandescent roadmap, accelerate the elimination of inefficient lighting products. China has also since 1996 began to implement green lighting projects to promote further energy-saving emission reduction. So the incandescent lamp has gradually faded out of daily life and production.
