Description

Technical Field

[0001] The present invention relates to the technical field of LEDs, and particularly to a spectral LED light source for yellow lionfish farming and a preparation method thereof. Background Art

[0002] Yellow lionfish has extremely high edible value. Its meat is delicate, smooth and has a unique taste. It belongs to high-grade edible fish, especially having a high status in Japanese and Korean cuisine. At the same time, yellow lionfish also has certain economic value. The artificial breeding technology of yellow lionfish in southern China has been very mature, while the northern region is exploring the "sea-land relay farming mode". The success of yellow lionfish fry breeding can get rid of the long-term dependence on wild resources and provide excellent breeding resources for the development of new production modes such as deep-sea farming in China.

[0003] Therefore, the artificial breeding technology is very crucial, and the light environment is particularly important for fishery farming. Currently, the light environment for farming mainly uses the spectrum obtained by filtering sunlight through a filter film. This light environment cannot meet the problems of night light supplementation and unstable light environment caused by weather changes.

[0004] See Figures 7 - 8 Select test points 1, 2, and 3 calibrated in the indoor yellow lionfish farming area to conduct sunlight spectrum tests at different time periods.

[0005] Further see Figures 9 - 12 , at 11:00 am, conduct indoor light environment spectrum tests and outdoor sunlight spectrum tests on test points 1, 2, and 3. The illuminance Ev (lx) of each test point varies greatly, and the chromaticity coordinate x, y values also vary greatly. Further see Figures 13 - 16 , at 11:30 am, conduct indoor light environment spectrum tests and outdoor sunlight spectrum tests on test points 1, 2, and 3. The illuminance Ev (lx) of each test point varies greatly, and the chromaticity coordinate x, y values also vary greatly.

[0006] Further see Figures 17 - 20 , at 12:00 noon, conduct indoor light environment spectrum tests and outdoor sunlight spectrum tests on test points 1, 2, and 3. The illuminance Ev (lx) of each test point varies greatly, and the chromaticity coordinate x, y values also vary greatly.

[0007] Further see Figures 21 - 24 , at 12:30 noon, conduct indoor light environment spectrum tests and outdoor sunlight spectrum tests on test points 1, 2, and 3. The illuminance Ev (lx) of each test point varies greatly, and the chromaticity coordinate x, y values also vary greatly.

[0008] Further see Figures 25 - 28, at 13:00 p.m., indoor light environment spectrum tests and outdoor sunlight spectrum tests were conducted on Test Point 1, Test Point 2, and Test Point 3. The illuminance Ev (lx) of each test point varied greatly, and the chromaticity coordinates x and y values also differed significantly.

[0009] See further Figures 29 - 32 , at 14:00 p.m. (raining), indoor light environment spectrum tests and outdoor sunlight spectrum tests were conducted on Test Point 1, Test Point 2, and Test Point 3. The illuminance Ev (lx) of each test point varied greatly, and the chromaticity coordinates x and y values also differed significantly.

[0010] In summary, it can be seen that the spectrum filtered by sunlight and a filter film in the current indoor yellowtail amberjack breeding area has problems of unstable spectrum, unstable light irradiance, and unstable light cycle and time. Summary of the Invention
