Description

Technical Field

[0001] The invention relates to the technical field of LEDs, and in particular to a spectrum LED light source for yellowtail fish breeding and a preparation method thereof. Background Art

[0002] Yellowtail has a very high edible value. Its meat is delicate and smooth, and its taste is unique. It is a high-end edible fish, especially in Japanese and Korean cuisine. At the same time, yellowtail also has a certain economic value. The artificial breeding technology of yellowtail in southern China is already very mature, while the northern region is exploring the "sea-land relay breeding model". The success of yellowtail seed breeding can get rid of the situation of long-term dependence on wild resources and provide excellent breeding resources for the development of new production models such as deep-sea breeding in China.

[0003] Therefore, artificial breeding technology is very critical, and the light environment is particularly important for fish farming. At present, the light environment for aquaculture mainly uses sunlight plus a filter membrane and then filtered spectrum. This light environment cannot meet the problem of unstable light environment caused by night supplementary light and weather changes.

[0004] See Figures 7-8 Test points 1, 2 and 3 calibrated in the indoor yellowtail fish breeding area were selected to conduct solar spectrum tests in different time periods.

[0005] See further Figures 9 to 12 At 11:00 am, indoor light environment spectrum test and outdoor sunlight spectrum test were conducted on test points 1, 2 and 3. The illuminance Ev(lx) of each test point was very different, and the chromaticity coordinates x and y values ​​were also very different. Figures 13-16 At 11:30 a.m., indoor light environment spectrum tests and outdoor sunlight spectrum tests were conducted on test points 1, 2, and 3. The illuminance Ev (lx) of each test point varied greatly, and the chromaticity coordinates x and y values ​​also varied greatly.

[0006] See further Figures 17-20 At 12 noon, indoor light environment spectrum tests and outdoor sunlight spectrum tests were carried out on test points 1, 2 and 3. The illuminance Ev (lx) of each test point was very different, and the chromaticity coordinates x and y values ​​were also very different.

[0007] See further Figures 21 to 24 At 12:30 noon, indoor light environment spectrum tests and outdoor sunlight spectrum tests were carried out on test points 1, 2 and 3. The illuminance Ev (lx) of each test point was very different, and the chromaticity coordinates x and y values ​​were also very different.

[0008] See further Figures 25 to 28At 13:00 in the afternoon, indoor light environment spectrum tests and outdoor sunlight spectrum tests were carried out on test points 1, 2 and 3. The illuminance Ev (lx) of each test point was very different, and the chromaticity coordinates x and y values ​​were also very different.

[0009] See further Figures 29 to 32 At 14:00 in the afternoon (raining), indoor light environment spectrum tests and outdoor sunlight spectrum tests were conducted on test points 1, 2 and 3. The illuminance Ev (lx) of each test point varied greatly, and the chromaticity coordinates x and y values ​​also varied greatly.
