Description

Technical Field

[0001] This utility model relates to an underwater multispectral plant production lamp and water tank, belonging to the field of lighting technology. Background Technology

[0002] In agricultural planting and related plant cultivation, light conditions play a crucial role in plant growth, development, and metabolic processes. The solar spectrum in natural light contains various wavelengths of light required for physiological activities such as photosynthesis, serving as the primary energy source for plant growth in the natural environment. However, in many practical applications, natural light often fails to meet the needs of plant growth. For example, in agricultural greenhouses, the structure blocks natural light at certain times, resulting in insufficient light intensity; agricultural research institutes need to precisely control light conditions to simulate different environments when conducting research on specific plant varieties; agricultural ecological parks may require providing suitable light for plants over a long period to create unique landscape effects; and landscape plants in large office spaces also require supplemental lighting due to limited indoor natural light.

[0003] Underwater multispectral plant production lights are artificial light sources developed based on the principles of plant growth and simulating the solar spectrum. They possess full-spectrum characteristics and a wide radiation range, which can compensate for the insufficiency of natural light to a certain extent, providing a suitable lighting environment for plant growth. In particular, the spectral distribution of full-spectrum plant lights is highly similar to the solar spectrum, making them an ideal supplemental lighting source for agricultural greenhouses, agricultural research institutes, agricultural ecological parks, and large office landscape planting applications.

[0004] However, existing underwater multispectral plant production lighting fixtures have shortcomings in the field of seaweed cultivation. Currently, most seaweed plant lighting fixtures are designed for surface environments, providing light to seaweed through surface illumination. Even those fixtures that can be submerged generally have low power. This results in seaweed not receiving sufficient light intensity in deep water areas, failing to reach the light intensity required for photosynthetic and respiration in equal amounts, thus affecting the seaweed's growth rate, quality, and yield. Utility Model Content

[0005] The purpose of this utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0006] The technical solution provided by this utility model is as follows: an underwater multispectral plant production lamp includes a heat dissipation column, a transparent outer shell, an upper cavity cover, and a lower cavity cover. The heat dissipation column is hollow inside, and a light source plate is provided on the outer periphery of the heat dissipation column. Threaded joints are also provided at both ends of the heat dissipation column. The transparent outer shell is fitted over the heat dissipation column. The upper cavity cover and the lower cavity cover are respectively connected to the upper and lower ends of the heat dissipation column through threaded joints. The upper cavity cover and the lower cavity cover are also provided with slots, and the two ends of the transparent outer shell are respectively engaged in the slots of the upper cavity cover and the lower cavity cover.

[0007] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: First, this utility model uses a heat dissipation column as the core structure, and installs the light source board on its outer periphery. The heat dissipation column allows the light emitted by the light source board to illuminate from all angles in a 360° all-round direction. Compared with existing underwater lamps that can only illuminate from one side or in a localized area, the all-round lighting mode can ensure that all parts of underwater plants such as seaweed in deep water areas can be evenly illuminated. Second, the hollow heat dissipation column structure of this utility model can increase the heat dissipation area and accelerate the conduction and dissipation of heat, allowing the lamp to install a high-power light source board to meet the high-intensity light requirements of deep-sea seaweed cultivation. In addition, this utility model uses a transparent shell to cover the heat dissipation column. The upper and lower cavity covers are connected to the upper and lower ends of the heat dissipation column by threaded joints, and the two ends of the transparent shell are respectively snapped into the slots of the upper and lower cavity covers. This can effectively prevent water from entering the lamp and protect the light source board, circuit and other key components from water corrosion and damage, thus ensuring the stable operation of the lamp underwater.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the heat dissipation column is a polyhedron or a cylinder.

[0010] The beneficial effects of adopting the above-mentioned further solutions are that both shapes are conducive to the installation and arrangement of the light source plate, so that the light can be distributed more evenly and meet the needs of underwater plants for all-round lighting. Among them, the polyhedral structure can increase the surface area of ​​the heat dissipation column, thereby enhancing the heat dissipation effect.

[0011] Furthermore, it also includes a cable outlet cavity cover, the upper cavity cover is provided with external threads, the cable outlet cavity cover is connected to the upper cavity cover by a first nut, and a sealing gasket is provided between the upper cavity cover and the cable outlet cavity cover.

[0012] The beneficial effects of adopting the above-mentioned further solution are that it provides a dedicated channel for cable outgoing, making the cable layout more neat and orderly. The upper cavity cover is provided with external threads and the cable outgoing cavity cover is connected through the first nut, which makes installation and disassembly convenient and facilitates the maintenance and repair of the lamp. The setting of the sealing gasket can prevent water from entering the lamp from the cable outgoing part.

[0013] Furthermore, it also includes a waterproof connector for leading out the cable, the waterproof connector being connected to the cable lead-out cavity cover, the inner cavity of the cable lead-out cavity cover, the inner cavity of the waterproof connector, and the inner cavity of the heat dissipation column being connected.

[0014] The advantage of adopting the above-mentioned further solution is that the waterproof joint can ensure that the cable remains sealed during the outgoing process.

[0015] Furthermore, it also includes a sling for suspending and mounting the underwater multispectral plant production lamp.

[0016] The advantage of adopting the above-mentioned further solution is that the light fixture can be conveniently suspended from the water tank or other suitable locations using the hanging ring.

[0017] Furthermore, a sealing ring is also provided inside the slot.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it enhances the sealing performance between the transparent shell and the upper and lower cavity covers.

[0019] Furthermore, the upper cavity cover is provided with a through hole, and the upper cavity cover is sleeved on the threaded joint at the upper end of the heat dissipation column and fixed by a second nut.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, while fixing the upper cavity cover, the second nut can also provide axial fixation for the transparent outer shell. Since the two ends of the transparent outer shell are engaged in the slots of the upper and lower cavity covers, when the upper cavity cover is fastened to the heat dissipation column by the second nut, it will exert a downward pressure on the transparent outer shell, making it more tightly engaged in the slots. When the lamp needs maintenance, repair or replacement of internal components, simply unscrew the second nut to disassemble the upper cavity cover and the transparent outer shell in sequence, and then inspect, repair or replace the light source board, circuit, etc. inside the heat dissipation column.

[0021] A water tank includes a tank body and an underwater multispectral plant production lamp. The tank body is provided with a plurality of horizontal bars at intervals, and a plurality of the multispectral plant production lamps are suspended on each horizontal bar.

[0022] The beneficial effect of adopting the above-mentioned further solution is that by applying underwater multispectral plant production lights to a water tank and suspending multiple lights by setting multiple horizontal bars on the tank, a highly efficient underwater plant lighting system is formed.

[0033] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and do not imply any priority in order or any specific technical meaning. Furthermore, the concepts of "connection" and "linkage" mentioned in this application, unless otherwise specified, are considered to include both direct connection (linkage) and indirect connection (linkage).

[0034] When interpreting the description of this application, it should be clarified that terms such as "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating directions or positional relationships, are based on the perspective and layout shown in the accompanying drawings. They are intended to facilitate explanation and simplify the description process, and are not absolute limitations on the actual location, construction method, or operating mode of the described device or element. Therefore, these terms should not be construed as restrictive interpretations of the content of this application.

[0035] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0036] like Figures 1-6 As shown, an underwater multispectral plant production lamp includes a heat dissipation column 101, a transparent outer shell 102, an upper cavity cover 103, and a lower cavity cover 104. The heat dissipation column 101 is hollow inside, and a light source plate 105 is provided on the outer periphery of the heat dissipation column 101. Threaded connectors 106 are also provided at both ends of the heat dissipation column 101. The transparent outer shell 102 is fitted over the heat dissipation column 101. The upper cavity cover 103 and the lower cavity cover 104 are respectively connected to the upper and lower ends of the heat dissipation column 101 through the threaded connectors. The upper cavity cover 103 and the lower cavity cover 104 are also provided with slots 107, and the two ends of the transparent outer shell 102 are respectively engaged in the slots 107 of the upper cavity cover 103 and the lower cavity cover 104.

[0037] The shape of the heat dissipation column 101 is not limited in the embodiments of this utility model. The heat dissipation column 101 can adopt a polyhedral structure, such as a trihedron, tetrahedron, octahedron, etc., or it can adopt a cylindrical structure. As long as the shape of the heat dissipation column 101 is conducive to the installation and arrangement of the light source plate 105, so that the light can be distributed more evenly and meet the needs of underwater plants for all-round lighting. Among them, the tetrahedral structure is the preferred solution because the tetrahedral structure can increase the surface area of ​​the heat dissipation column 101, thereby enhancing the heat dissipation effect.

[0038] The multispectral plant production lamp 100 also includes a cable outlet cover 108. The upper cover 103 has external threads, and the cable outlet cover 108 is connected to the upper cover 103 by a first nut 109. The first nut 109 can be a union nut, and a sealing gasket 110 is provided between the upper cover 103 and the cable outlet cover 108. The cable outlet cover 108 provides a dedicated channel for cable outlet, making the cable layout more neat and orderly. The upper cover 103 has external threads and is connected to the cable outlet cover 108 by the first nut 109, making installation and disassembly convenient and facilitating lamp maintenance and repair. The sealing gasket 110 prevents water from entering the lamp from the cable outlet.

[0039] The multispectral plant production lamp 100 also includes a waterproof connector 114 for leading out the cable. The waterproof connector 114 is connected to the cable lead-out cavity cover 108, and the inner cavity of the cable lead-out cavity cover 108, the inner cavity of the waterproof connector 114, and the inner cavity of the heat dissipation column 101 are in communication. The waterproof connector 114 ensures that the cable remains sealed during the lead-out process.

[0040] The multispectral plant production lamp 100 also includes a hanging ring 113 for suspending and mounting the underwater multispectral plant production lamp 100. The lamp can be conveniently suspended in the water tank 200 or other suitable location via the hanging ring 113.

[0041] The slot 107 is also provided with a sealing ring 111, which enhances the sealing performance between the transparent shell 102 and the upper cavity cover 103 and the lower cavity cover 104.

[0042] The upper cavity cover 103 has a through hole and is fitted onto the threaded joint 106 at the upper end of the heat dissipation column 101, and is fixed by the second nut 112. The second nut 112 not only fixes the upper cavity cover 103 but also provides axial fixation for the transparent outer shell 102. Since both ends of the transparent outer shell 102 are engaged in the slots 107 of the upper cavity cover 103 and the lower cavity cover 104, when the upper cavity cover 103 is tightened onto the heat dissipation column 101 by the second nut 112, it exerts a downward pressure on the transparent outer shell 102, making it more tightly engaged in the slots 107. When the lamp needs maintenance, repair, or replacement of internal components, simply unscrew the second nut 112 to disassemble the upper cavity cover 103 and the transparent outer shell 102 in sequence, and then inspect, repair, or replace the light source board 105, circuitry, etc., inside the heat dissipation column 101.

[0043] like Figure 7 and Figure 8As shown, a water tank includes a tank body 201 and the aforementioned underwater multispectral plant production lamps 100. Multiple horizontal bars 202 are spaced apart on the tank body 201, and multiple multispectral plant production lamps 100 are suspended from each horizontal bar 202. By applying the underwater multispectral plant production lamps 100 to the water tank 200 and suspending multiple lamps from the multiple horizontal bars 202 on the tank body 201, a highly efficient underwater plant lighting system is formed.

[0044] The design principle of this underwater multispectral plant production lamp 100 is as follows:

[0045] This invention uses a heat dissipation column 101 as its core structure, with the light source plate 105 mounted on its outer periphery. The heat dissipation column 101 allows the light emitted from the light source plate 105 to illuminate from all angles in a 360° omnidirectional manner. Compared with existing underwater lights that illuminate above water or only from one side or in a localized area, this omnidirectional lighting mode ensures that all parts of underwater plants such as algae in deep water areas receive uniform light. The hollow heat dissipation column 101 structure of this invention increases the heat dissipation area, accelerates heat conduction and dissipation, and allows the light fixture to install a high-power light source plate 105, meeting the high-intensity light requirements for deep-sea algae cultivation.

[0046] In terms of sealing design, this utility model uses a transparent outer shell 102 fitted over the heat dissipation column 101. The upper cavity cover 103 and the lower cavity cover 104 are respectively connected to the upper and lower ends of the heat dissipation column 101 via threaded joints 106. The two ends of the transparent outer shell 102 are respectively snapped into the slots 107 of the upper cavity cover 103 and the lower cavity cover 104, that is, the transparent outer shell 102 is sandwiched between the upper cavity cover 103 and the lower cavity cover 104. When the second nut 112 is tightened, the upper cavity cover 103, the lower cavity cover 104 and the transparent outer shell 102 can be tightly combined. A sealing ring 111 is provided between the transparent outer shell 102 and the upper cavity cover 103 and the lower cavity cover 104. Through these structural components, water can be effectively prevented from entering the lamp, protecting the light source board 105, circuit and other key components from water corrosion and damage, ensuring that the lamp can work normally underwater for a long time. In addition, the upper cavity cover 103 is provided with external threads, and the inner side of the cable outlet cavity cover 108 is provided with internal threads. The two are connected by threads, and a sealing ring 111 is provided at the connection to provide a sealing and waterproof function. The upper side of the cable outlet cavity cover 108 is provided with threads, which can be connected to the waterproof connector 114 for cable outgoing. The housing is also provided with a lifting ring 113 for the suspension installation of the lamp.

[0047] Taking the cultivation of aquatic plants such as seaweed as an example, the lamps are completely immersed in a water tank 200. Their 360-degree light emission characteristics can greatly increase the power per unit of water, reduce light loss, improve energy utilization, and thus promote plant growth.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
