Description

LED lighting system for factory fish farming with adjustable color temperature

Technical field:

The invention belongs to the field of aquaculture equipment, and in particular relates to a light-emitting diode lighting system for factory fish farming with adjustable color temperature.

Background technique:

As a complex and special external ecological factor in the aquatic environment, light includes spectrum, light intensity and photoperiod. The latest results show that light spectrum can significantly affect the stress response, physiological state and behavior of farmed fish, thereby affecting their growth performance. However, at present, due to the lack of sufficient understanding of the importance of artificial light control, the lighting sources commonly used in domestic seawater fish factory breeding workshops are still incandescent lamps or fluorescent tubes. The disadvantages are: poor lighting intensity and uneven illumination , large changes in wavelength range, poor penetration and stability, etc. Light-emitting diode (LED) is called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, strong illumination, and high stability. More importantly, because the LED light source has relatively single spectral characteristics, so It can produce relatively pure monochromatic light, for example, a blue LED has a single peak at a wavelength of 470nm. The spectral peaks of incandescent lamps are widely distributed in the blue region of more than 400nm to the near-infrared region of more than 700nm, and the luminous intensity can also be observed in the ultraviolet region and infrared region. Because the monochromatic LED light source has the characteristic of typical peak spectrum, the principle of red, green and blue can be used to combine the three colors arbitrarily under the control of computer technology, so as to form a combination of different light colors and realize rich and colorful lighting effects. Dynamic changes. Due to the unique spectral characteristics of LED, it can be used in many fields such as agricultural production, animal husbandry, and aquaculture. At present, in the field of agriculture, LED lighting technology has become an emerging technology of modern agriculture. Research has found that the red and blue light that combines red LEDs and blue LEDs at a ratio of 9:1 is the most beneficial to plant growth. After this light source is irradiated, strawberries and tomatoes are plump. The content of sugar and vitamin C is significantly increased, but its disadvantage is that it cannot achieve stepless adjustment of color temperature; in the chicken industry, because LED lights have the characteristics of semiconductor packaging and anti-humidity, plus adjustable light is used to control the ambient light source , can provide the most suitable growth ring for chickens; in February 2010, at the Atlanta International Poultry Breeding Equipment Exhibition, ONCE company AGRISHIFTTM launched a gradual change poultry breeding LED light, which uses a timer to achieve photoperiod control, which is relatively simple , but it only adjusts the light intensity and photoperiod, which does not meet the needs of different poultry and different growth stages for light color, light intensity and photoperiod. At present, LED special products for animal husbandry need to be further developed. In recent years, some developed countries in the world have begun to try to apply LED light sources to the lighting of small ornamental fish farming, but there are no reports at home and abroad on the LED light sources developed for the cultivation of industrialized marine fish breeding seedlings.
