Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and more specifically to a lighting system for aquaculture. Background Technology

[0002] A lighting system is a comprehensive system that combines specific light sources, lamps, control devices, and related auxiliary equipment according to certain design requirements and technical specifications to provide suitable lighting conditions for a specific space or environment. It is widely used in many fields such as aquaculture, marine engineering, modern agriculture, plant factories, and biomedicine.

[0003] Taking aquaculture as an example, lighting systems can provide suitable lighting conditions for aquatic organisms such as fish, shrimp, and crabs, optimize the aquaculture environment, promote their growth, development, and reproduction, and help increase production and improve quality. In practical applications, due to significant differences in the actual environment of the aquaculture area, the installation space of the lighting system, and the individual needs of the aquaculture organisms, the distribution of light intensity of different colors of light in the aquaculture area is uneven, reducing the efficiency of the lighting system.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

In one or more embodiments, the light-emitting plate 11 further includes a control chip (not shown) that forms a communication connection with the LED beads 111, thereby conveniently controlling the turning on, turning off and output power of the LED beads 111 and providing control precision.

[0031] like Figure 2 As shown, in one or more embodiments, a portion of the light conversion plate 12 of the illumination device 10 has monochromatic quantum dots 122. In other words, this portion of the light conversion plate 12 of the illumination device 10 contains only quantum dots of a single color. The monochromatic quantum dots 122 include at least one of green quantum dots, yellow quantum dots, and red quantum dots. The material of the monochromatic quantum dots 122 may be, but is not limited to, CdTe, CdSe, InP, InAs, CsPbBr3, or CsPbBr x / I 3-xQuantum dots exhibit a quantum confinement effect. When blue (or violet) light shines on a monochromatic quantum dot 122, the dot absorbs the light, exciting its internal electrons to a higher energy level. Upon transitioning back to a lower energy level, the electrons release energy as photons, emitting light of a specific wavelength, such as green, yellow, or red. In one or more embodiments, the wavelength range of the light emitted by green quantum dots is 510nm-550nm, for example, 510nm, 520nm, 530nm, 540nm, 550nm, etc. In one or more embodiments, the wavelength range of the light emitted by yellow quantum dots is 560nm-600nm, for example, 560nm, 570nm, 580nm, 590nm, 600nm, etc. In one or more embodiments, the wavelength of the light emitted by the red quantum dots is in the range of 610nm-650nm, for example, 610nm, 620nm, 630nm, 640nm, 650nm, etc.

[0032] See also Figure 2 In one or more embodiments, the light conversion plate 12 further includes a substrate 121 for accommodating monochromatic quantum dots 122. The substrate 121 may be made of, but is not limited to, PS or PC. In one or more embodiments, the thickness of the substrate 121 is 1.5mm-2.5mm, for example, 1.5mm, 2mm, 2.5mm, etc. The shape of the substrate 121 is not limited, as long as it can be matched with the light-emitting plate 11. In one or more embodiments, the light transmittance of the substrate 121 is 50%-60%, for example, 50%, 55%, 60%, etc. In one or more embodiments, the mass ratio between the monochromatic quantum dots 122 and the substrate 121 is greater than or equal to 0.125% and less than or equal to 2%. For example, the mass ratio between green quantum dots and the substrate 121 is 1.67%; the mass ratio between yellow quantum dots and the substrate 121 is 1.67%; the mass ratio between red quantum dots and the substrate 121 is 0.167%, etc. Through the above settings, the monochromatic quantum dots 122 can be added in a suitable amount, ensuring the luminous efficiency and luminous intensity of the second light.

[0033] like Figure 3As shown, in one or more embodiments, the light conversion plate 12 of the remaining lighting device 10 has color-mixing quantum dots 123. In other words, the light conversion plate 12 of this part of the lighting device 10 is provided with quantum dots of two or more colors. The color-mixing quantum dots 123 include at least one of red-green color-mixing quantum dots 123, red-yellow color-mixing quantum dots 123, yellow-green color-mixing quantum dots 123, and red-yellow-green color-mixing quantum dots 123. Taking the red-green color-mixing quantum dot 123 as an example, the color-mixing quantum dot 123 contains both red and green quantum dots. When the first light on the light-emitting plate 11 shines on the light conversion plate 12 with red-green color-mixing quantum dots 123, the red and green quantum dots are excited to produce a second light that is approximately yellow. Therefore, the lighting system 1 of this utility model, through the combined use of monochromatic quantum dots 122 and color-mixing quantum dots 123, can make the light intensity of different colors of light (including the first light and the second light) uniformly distributed in the breeding area 2, avoiding excessive differences in light intensity at different locations that would affect the breeding effect. In one or more embodiments, the mass ratio between each color quantum dot and the substrate 121 in the color-mixing quantum dot 123 is greater than or equal to 0.125% and less than or equal to 2%. For example, in the red-green color-mixing quantum dot 123, the mass ratio between the red quantum dot and the substrate 121 is 0.167%, while the mass ratio between the green quantum dot and the substrate 121 is 1.67%. It should be noted that the parts not mentioned in the second embodiment of the illumination device 10 can be configured the same as in the first embodiment, and will not be described again here.

Each lighting device 10 measures 60cm x 60cm; the LED beads 111 in the light-emitting panel 11 have an output power of 78W; the spacing between adjacent lighting devices 10 is 30cm; and the distances between each row of lighting devices 10 and the water surface of the aquaculture area 2, from left to right, are 110cm, 137cm, 165cm, 165cm, 137cm, and 110cm respectively. Testing revealed that the light intensity at various points on the water surface within the aquaculture area 2 ranged from 2500lx to 3000lx (lux), and the PPFD (Photosynthetic Photon Flux Density) ranged from 30μmol / (m²). 2 ·s) -35μmol / (m 2 ·s). For example Figure 6 As shown, the ratio of blue, green and red light intensity at various points on the water surface in aquaculture area 2 is 5:8:4.
