Description

Technical Field

[0001] This utility model relates to the field of microalgae cultivation, and in particular to a light regulation device for indoor microalgae cultivation. Background Technology

[0002] In the field of algae cultivation, some algae possess unique color-changing characteristics, a phenomenon that presents new challenges and research directions for algae cultivation technology. Many algae undergo color changes during their growth cycle or under specific environmental stimuli. For example, some diatoms may change from brown to yellow when nutrient concentrations change; some red algae will gradually change from bright red to pale red or even orange when light intensity and temperature fluctuate.

[0003] Color changes in algae are often accompanied by alterations in their internal physiological structure and biochemical composition. The light requirements of algae after color change differ significantly from those before. Taking green algae as an example, in their normal green state, they primarily rely on chlorophyll to absorb light energy for photosynthesis, exhibiting high absorption efficiency for blue and red light, and their suitable light intensity range is usually within a certain range. However, when green algae change color due to environmental factors, such as turning yellow, their photosynthetic pigment composition changes, with a relative increase in the content of other pigments such as carotenoids. This shifts the light absorption spectrum, potentially enhancing their ability to utilize green light while reducing their need for blue and red light, and narrowing their suitable light intensity range.

[0004] The change in light requirements following this color change places extremely stringent demands on light control in algae cultivation. Traditional single-light patterns are no longer sufficient to meet the growth needs of algae during this process. In large-scale algae cultivation, if light conditions are not precisely adjusted in real time according to the color changes of the algae, the growth rate of the algae will slow down, biomass accumulation will decrease, and it may even lead to algae death, severely impacting cultivation efficiency. Furthermore, because the triggering factors for algal color change are complex and diverse, including numerous environmental variables such as nutrient composition, water quality, temperature, and light duration, accurately predicting and promptly responding to changes in algal color change and corresponding light requirements has become a pressing issue in the development of algae cultivation technology. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a high-precision light adjustment device, including LED beads of different colors. A lampshade covers the LED beads on the first surface of a housing, and the lampshade and housing are ultrasonically welded together. The LED beads are arranged in a ring inside the lampshade. A fixing part is fixedly installed on the second surface of the housing, facilitating the installation of the light adjustment device. It also includes an imaging device, switches, and adjustment knobs. Each switch controls multiple LED beads of the same color, and each adjustment knob simultaneously controls the brightness of all LED beads. The LED beads of different colors provide the algae with the light required for their growth. Because algae have varying absorption and utilization efficiencies for different wavelengths of light, providing LED beads emitting specific spectra can promote algal growth and improve the photosynthetic efficiency of algae.

[0006] Preferably, the LEDs contain red, blue-violet, and green light. Blue-violet light promotes algal cell growth and division, while red light promotes carbon assimilation during photosynthesis, helping algae fix carbon dioxide into organic compounds and providing the material basis for algal growth. During the algal growth and reproduction stage, more red and blue-violet light are needed. However, in the subsequent stages of nutrient production, such as carotene and carotenoids, the need for red light decreases; excessive red light can also lead to photo-oxidative damage. Blue-violet and green light, on the other hand, help further accumulate nutrients.

[0007] Preferably, the ratio of red light to blue-violet light during the growth stage is 3:1. As algae grow, their light spectrum requirements change significantly when they enter the crucial stage of nutrient production. At this time, nutrients such as carotene and carotenoids begin to be synthesized and accumulated in large quantities. During this stage, the algae's need for red light decreases significantly because excessive red light can trigger a series of adverse photo-oxidation reactions, damaging algal cells. Blue-violet and green light, on the other hand, play a positive role in promoting further nutrient accumulation. An appropriate ratio of blue-violet and green light provides the perfect energy and environmental conditions for nutrient synthesis and accumulation. Blending red, blue-violet, and green light in a 5:4:1 ratio effectively promotes efficient nutrient accumulation, improving the quality and economic value of the algae.

[0008] Preferably, the control of the light color ratio is accomplished by software, reducing the hassle of manual operation. This intelligent control method greatly reduces the errors and inconveniences that may occur during manual operation, achieving automated and precise adjustment of the light spectrum. Users only need to input relevant parameter information such as the type and growth stage of algae into the software system, and the software can automatically calculate and control the on / off state of each LED and the light color ratio according to preset algorithms and models, ensuring that the lighting conditions are always perfectly matched with the growth needs of the algae.

[0009] It also includes an adjustment knob, which can adjust the overall light intensity, as algae require different light intensities at different growth stages.

[0010] The aforementioned high-precision light adjustment device is fixed in the algae cultivation device via a fixing part. Since water circulation occurs continuously during growth, the cultivation device operates in a relatively humid environment, requiring waterproofing. The first surface of the outer shell has a drying part and a drying part fixing groove. The drying part fixing groove has a removable plate on the second surface of the outer shell. The drying part, containing a solid desiccant, is placed in the drying part fixing groove. A waterproof sealing part, preferably a rubber sealing strip, is located at the junction of the groove and the outer shell. The desiccant can be replaced via the removable plate, ensuring continuous and effective water absorption. The sealing strip prevents seal failure during desiccant replacement. The sealing strip and desiccant ensure a relatively dry working environment for the high-precision light adjustment device, extending its service life.

[0011] Microalgae cultivation inevitably produces water mist and creates extreme environments with high humidity. To achieve better lighting effects, it is necessary not only to optimize the light color and intensity but also to ensure waterproofing for long-term use.

[0012] Advantages of this utility model:

[0013] 1. It can provide appropriate wavelengths and intensities of light according to different stages of microalgae growth, and the entire process is automatically controlled by software, reducing the need for manual labor;

[0014] 2. The waterproof structure is simple and efficient. The lampshade and upper shell are ultrasonically welded, effectively preventing the intrusion of most moisture. Additionally, a sealing strip and solid desiccant are provided as backup protection. In the event of trace moisture penetration or extremely high humidity environments, the desiccant absorbs residual moisture, further reducing internal humidity. This multi-layered protection mechanism effectively ensures that the structure can operate stably for extended periods in complex and high-humidity environments, continuously maintaining its waterproof performance.

[0016] Figure 2 This is a front view schematic diagram of a high-precision illumination adjustment device. Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] like Figure 1 and Figure 2The high-precision illumination adjustment device shown includes a red LED bead 1, a blue-violet LED bead 2, a green LED bead 3, a slot 4, a fixing part 5, a lamp cover 7, and a housing 8.

[0019] Various colored LED beads are installed between the lampshade 7 and the outer shell 8. The number of LED beads of each color is the same, which facilitates subsequent calculation of the ratio. In the complex light control system of microalgae cultivation, the light emitted by different colored LED beads has a completely different effect on the growth of algae. This setting can accurately and conveniently adjust the number and combination ratio of different colored LED beads according to the specific needs of different growth stages of algae, thereby achieving fine customization of the light spectrum. This meets the special absorption and utilization needs of algae for specific wavelengths of light at each critical growth stage, laying a solid light foundation for the healthy growth and efficient reproduction of algae.

[0020] The lampshade 7 and the outer casing 8 are ultrasonically welded together. The outer casing 8 has a drying section and a drying section fixing groove 4 on its first surface. The drying section fixing groove 4 has a removable plate on its second surface. The drying section, containing a solid desiccant, is placed in the drying section fixing groove 4. This solid desiccant ensures that the lampshade 7 and the outer casing 8 remain dry, providing support for continuous operation of the equipment. A removable plate is also located at the connection between the groove 4 and the back of the outer casing 8, allowing for replacement of the solid desiccant. A waterproof seal is also provided to prevent seal failure due to desiccant replacement.

[0021] In the actual environment of microalgae cultivation, the continuous operation of the water circulation system often leads to a significant increase in ambient humidity, making the space where the lamps are located highly humid. Under high humidity, a large number of water droplets will inevitably condense on the surface of the lampshade 7. Once these water droplets form, they will have a severe negative impact on the light supply efficiency of the lamp beads. On the one hand, the water droplets will refract and scatter the light, causing the light that should accurately illuminate the microalgae cultivation area to deviate and disperse, resulting in a significant reduction in light intensity and uniformity. On the other hand, water droplets that adhere to the lampshade 7 for a long time may gradually penetrate into the lampshade, causing erosion and damage to the lamp beads themselves, thereby reducing the luminous efficiency of the lamp beads, shortening their lifespan, and seriously hindering the normal operation and stable functioning of the microalgae cultivation lighting system. Solid desiccants can actively absorb moisture from the surrounding air, thereby effectively reducing the air humidity between the lampshade 7 and the outer shell 8.

[0022] A fixing part 5 is provided on the outer shell 8 for easy fixation in the microalgae cultivation device. It can take various forms, such as threaded fixing posts, adjustable snap-fit ​​structures, or magnetic adsorption components, to meet different installation scenarios and needs. The fixing part 5 not only ensures that the lamps will not shift or shake due to external factors such as water flow impact and equipment vibration during use, ensuring the stability and accuracy of the lighting, but also allows cultivators to easily disassemble and install the lamps when performing equipment maintenance, lamp replacement, or lighting parameter adjustment, greatly improving the practicality and operability of the microalgae cultivation lighting system.

[0023] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0024] While the specific embodiments of this utility model have been described above, they are not intended to limit the scope of protection of this utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of this utility model are still within the scope of protection of this utility model.
