According to relevant published literature or through experiments to obtain the optimal light environment parameters for fish's circadian rhythm, feeding behavior, growth and reproduction performance, the chip wavelength, power and electronic control system of the customized LED aquatic products selection light can be determined. At the same time, according to the chip packaging form, lens light distribution, lamp appearance, and protection level, the overall lamp can be designed, and scientifically applicable LED aquatic products selection light can be produced, which can be used in the lighting environment of aquaculture industry.

If customized LED aquatic products selection light has national, industry or local standards, it should meet the corresponding standard requirements; for special occasions where there is no national, industry or local standard, customized LED aquatic products selection light should at least meet the special occasions for aquaculture applications The following requirements.

1. Selection of light color, light intensity and light period

Melatonin has a certain regulatory effect on the hypothalamic-pituitary-gonad axis of fish. The rhythm of fish melatonin synthesis and secretion is mainly affected by light and temperature. Fish melatonin participates in the regulation of reproduction, development and growth. Light, especially the photoperiod, significantly inhibits the synthesis and secretion of melatonin in the pineal gland of fish. The three important factors for artificially creating a light environment are light color, light intensity and light period. Only given these three main parameters, the manufacturer of customized LED aquatic products selection light can produce lamps that meet the requirements.

2. Secondary light distribution design of lamps

The light distribution method of the lens and reflector of traditional lamps is basically not suitable for the light coverage requirements of fish ponds in aquatic workshops. Most of the shapes of circulating water fish ponds are regular geometric shapes, so the lens and reflector of customized LED aquatic products selection light should be matched together The design adopts high refractive index lens material, which not only needs to have uniform light spots on the water surface, but also covers the entire fish pond to save power. Secondly, according to the different depths of the fish pond, the luminous intensity of the light source should be considered and the formula should be used scientifically to accurately calculate.

3. Safety requirements for protection level

The protection level should meet the design requirements and meet the standards. The humidity in the aquaculture workshop is mostly above 90%, so the waterproof requirements for customized LED aquatic products selection light are relatively high, and the protection level standard must reach IP65. If the lamp is installed under the water in the aquaculture pond for energy saving, the IP level should be at least IP67.

4. Color temperature and color rendering index

The customized LED aquatic products selection light design must have color temperature (Tc) and color rendering index (Ra) requirements. The color temperature is expressed by Tc, and the unit is K. When the radiation of the light source in the visible region is exactly the same as the radiation of the absolute black body, the temperature of the black body at this time is called the color temperature of the light source. The red radiation of the low color temperature light source is relatively more, and the proportion of blue radiation will increase when the color temperature is increased.
