The light-emitting part is provided with LED light-emitting chips with various wavelength ranges; the light-emitting part is arranged in the transparent lampshade,and the transparent lampshade is filled with heat dissipation liquid. By applying the technical scheme of the embodiment of the invention, various spectral energies are provided, the spectral energies can be adjusted, the growth and metabolism requirements of algae can be met, the yield and quality of algae can be improved, the growth rate of algae can be increased, and the accumulated biomass energy can be enhanced.

Description

technical field [0001] The invention relates to the technical field of light-emitting diodes, in particular to a light-emitting diode (LED) supplementary light device for algae cultivation. Background technique [0002] With the development of modern aquaculture and biotechnology, the artificial cultivation of plants with high economic value or added value, especially algal plants, has gradually scaled up. The healthy growth and metabolism of algae plants requires sunlight. After long-term practice, researchers have gradually explored the light energy required by different growth stages of different algae plants to improve the utilization rate of light energy and improve the yield and quality of algae plants. Filling light is a lamp that uses light instead of sunlight to provide the light source required for plant growth and development according to the natural law of plant growth and the principle that plants use sunlight for photosynthesis.

AI Technical Summary

Problems solved by technology

[0003] At present, most algae farming or ecological lighting use fluorescent lamps or LEDs to provide light quantum. However, because the wavelength and energy of the existing supplementary light that provides light quantum cannot fully match the wavelength and energy required by algae, resulting in low light energy utilization. Low, cannot well meet the needs of algae photosynthesis with multiple light wavelengths and intensity, resulting in low growth rate of algae and poor ability to accumulate biomass

The existing plant fill light has a relatively single form of irradiation on plants, mostly fixed positions or in-situ rotations

On the other hand, the heat generated by the supplementary light is high, and the traditional heat dissipation methods can no longer meet the high energy demand of algae

[0004] For the above-mentioned problems existing in the prior art, no effective solution has been proposed yet
