Light emitting diode illumination system with adjustable color temperature for industrial fish farming

Abstract

The invention discloses a light emitting diode (LED) illumination system with an adjustable color temperature for industrial fish farming. in construe, the system comprises a power supply module, a white light LED module and a color temperature adjustment module, wherein the power supply module is respectively connected with the white light LED module and the color temperature adjustment module; the color temperature adjustment module is composed of a red light LED module, a green light LED module, a blue light LED module and a current control module; and the red light LED module, the green light LED module and the blue light LED module are respectively connected with the current control module in series. The light emitting diode illumination system with adjustable color temperature for industrial fish farming has the beneficial effects that the color temperature can be adjusted according to the practical situation in the farming process so as to satisfy requirements of different marine fishes in different growth periods on light color, light intensity and the light period, thereby accelerating fishes to healthily grow and improving the economic benefit of industrial fish farming.

Description

Technical field: [0001] 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: [0002] 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)...

AI Technical Summary

Problems solved by technology

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 , wavelength range changes greatly, penetrability and stability are not good, etc.

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 is no report on the LED light source developed for industrial seawater fish breeding at home and abroad.
