Description

Technical Field

[0001] This utility model relates to the field of LED light source technology, and in particular to an LED light source for photocatalytic reactions. Background Technology

[0002] LED light sources used in photocatalytic reactions are primarily applied to accelerate chemical reactions by exciting catalysts with light energy, playing a significant role in environmental remediation and energy conversion. They provide specific wavelengths and intensities of light for photocatalytic reactions, promoting reactions such as organic matter decomposition and water splitting for hydrogen production. Current devices typically require the following technologies in practical applications:

[0003] 1. Precise wavelength control technology to match the absorption characteristics of different catalysts;

[0004] 2. High brightness and uniform light output ensure efficient photocatalytic reaction;

[0005] 3. Excellent heat dissipation design prevents LEDs from overheating and affecting their performance and lifespan;

[0006] 4. A stable power supply drive system ensures stable operation of the light source.

[0007] Currently, various devices and methods are used to meet the light source requirements in photocatalytic reactions.

[0008] For example, a Chinese patent discloses a photocatalytic reaction lamp with a heat dissipation structure, patent number: CN221222644U. By setting a fluid channel, a fluid medium continuously flows in the fluid channel while the LED light source continuously emits light signals. The fluid medium contacts the side wall of the fluid channel and exchanges heat with the outer wall of the fluid channel, which can carry away the heat generated by the LED light source, so that the heat generated by the LED light source can be dissipated in time and ensure the normal operation of the LED light source.

[0009] However, the above method has a prominent problem: the various components in the device are installed separately, which may occupy a lot of space inside or around the reaction vessel. Furthermore, due to the dispersed nature of the components, each component needs to be fixed and connected separately during installation, which increases the difficulty and time of installation. Utility Model Content

[0010] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides an LED light source for photocatalytic reaction, which solves the technical problem that the components are installed separately, which may occupy a lot of space in or around the reaction vessel. Furthermore, due to the dispersion of components, each component needs to be fixed and connected separately during installation, which increases the difficulty and time of installation.

[0011] (II) Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution:

[0012] An LED light source for photocatalytic reactions includes two base plates. Each base plate has a mounting base fixedly connected to its upper end. Each mounting base has a rotating block rotatably connected inside it. Each rotating block has a rectangular groove inside it. Each mounting base has a limit rod threadedly connected inside it. The limit rods are respectively sleeved inside the rectangular grooves. A round rod is fixedly connected inside each rotating block. A support mechanism is provided at the upper end of each base plate. The support mechanism includes a support box, which is located at the upper end of the base plate.

[0013] Preferably, a cooling fan is provided at the upper end of the base plate, and the two mounting bases, the support box, and the cooling fan are all on the same horizontal line.

[0014] Preferably, an LED light source body is sleeved inside the support box, and a convex mirror baffle is slidably connected inside the support box.

[0015] Preferably, the convex mirror baffle has a slot inside.

[0016] Preferably, a spring is fixedly connected inside the support box, and a locking block is fixedly connected to the outer surface of the spring.

[0017] Preferably, a fluid pump is fixedly connected to the upper end of the base plate, and connecting pipes are sleeved inside the cooling fan, the LED light source body, and the fluid pump. A dovetail block is fixedly connected to the lower end of the base plate.

[0018] (III) Beneficial effects: 1. By inserting the round rod installed inside the rotating block into the round groove opened in the support box and the cooling fan, the cooling fan and the LED light source body are uniformly installed on the upper part of the base plate. During the installation operation, the base plate is directly installed in the photocatalytic reaction stage, which achieves the effect of rapid installation. Moreover, all components are laid out on the same plane, which reduces the space occupied by the device in different directions and makes the overall structure more compact. The more compact installation layout allows the cooling fan, fluid pump and connecting pipe to be closer to the LED light source body for heat dissipation, enhancing the heat dissipation effect and ensuring the stable operation of the LED light source body.

[0019] 2. During installation, hold the rotating block and screw it towards the end closest to the limiting rod. At this point, the limiting rod and the rectangular groove inside the rotating block are on the same horizontal line. Screw the rotating block until it fits against the surface of the mounting base. Then, hold the limiting rod and screw it 90 degrees. The lower end of the limiting rod is a threaded rod, which is threaded into the mounting base. During rotation, the limiting rod will slide downwards and fit against the surface of the rotating block. The surface of the limiting rod is cuboid in shape. The limiting rod limits and fixes the rotating block. After adjusting the installation direction of the limiting rod, screw the rotating block to complete the installation of the support box and cooling fan. The operation is simple and convenient, saving installation time and improving overall installation efficiency. Attached Figure Description

[0028] This application provides an LED light source for photocatalytic reactions, effectively solving the problem of scattered component installation, which may occupy a lot of space inside or around the reaction vessel. Furthermore, the dispersed components require separate fixing and connection during installation, increasing the difficulty and time involved. By inserting a circular rod installed inside the rotating block into the circular grooves in the support box and cooling fan, the cooling fan and LED light source body are uniformly mounted on the upper part of the base plate. During installation, the base plate is directly installed in the photocatalytic reaction stage, achieving rapid installation. Moreover, all components are arranged on the same plane, reducing the space occupied by the device in different directions and making the overall structure more compact. This more compact installation layout allows the cooling fan, fluid pump, and connecting pipes to be closer to the LED light source body for heat dissipation, enhancing the heat dissipation effect and ensuring the stable operation of the LED light source body.

[0029] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application embodiment effectively solves the technical problem that the dispersed installation of various components may occupy a lot of space inside or around the reaction vessel, and that due to the dispersion of components, the fixing and connection of each component needs to be handled separately during installation, which increases the difficulty and time of installation. The overall idea is as follows: An LED light source for photocatalytic reaction includes two base plates 11, each base plate 11 is fixedly connected to a mounting base 12 at its upper end, each mounting base 12 is rotatably connected to a rotating block 13, each rotating block 13 is provided with a rectangular groove 14 inside, and each mounting base 12 is threadedly connected to a limit rod 1. 5. Two limiting rods 15 are respectively sleeved inside two rectangular slots 14. Two rotating blocks 13 are fixedly connected with round rods 16. A support mechanism is provided at the upper end of the base plate 11. The support mechanism includes a support box 17, which is located at the upper end of the base plate 11. A cooling fan 18 is provided at the upper end of the base plate 11. The two mounting seats 12, the support box 17, and the cooling fan 18 are all on the same horizontal line. An LED light source body 19 is sleeved inside the support box 17. During installation, the surface of the rotating block 13 is held and screwed toward the end close to the limiting rod 15. At this time, the rectangular slots 14 opened in the limiting rod 15 and the rotating block 13 are closed. With the rotating block 13 aligned with the surface of the mounting base 12, tighten it to fit snugly. Then, hold the limiting rod 15 and tighten it 90 degrees. The lower end of the limiting rod 15 is threaded and threaded into the mounting base 12. During rotation, the limiting rod 15 slides downwards and fits snugly against the surface of the rotating block 13. The surface of the limiting rod 15 is cuboid in shape. The limiting rod 15 limits and fixes the rotating block 13. The round rod 16 installed inside the rotating block 13 is inserted into the round grooves opened in the support box 17 and the cooling fan 18. The cooling fan 18 and the LED light source body 19 are then uniformly installed on the upper end of the base plate 11. Then proceed with the installation... During installation, the base plate 11 is directly installed in the photocatalytic reaction stage, achieving a rapid installation effect. All components are laid out on the same plane, reducing the space occupied by the device in different directions and making the overall structure more compact. The more compact installation layout allows the components to be closer together for heat dissipation of the LED light source body 19, enhancing the heat dissipation effect and ensuring the stable operation of the LED light source body 19. The installation of the support box 17 and the cooling fan 18 can be completed by turning the installation direction of the limiting rod 15 and then turning the rotating block 13. The operation is simple and convenient, which helps to save the time required for installation and improve the overall installation efficiency.

[0030] A convex mirror baffle 21 is slidably connected inside the support box 17. The convex mirror baffle 21 is located at the end of the LED light source body 19 away from the cooling fan 18. A slot 22 is opened inside the convex mirror baffle 21. A spring 23 is fixedly connected inside the support box 17. A locking block 24 is fixedly connected to the outer surface of the spring 23 and engages inside the slot 22. A fluid pump 25 is fixedly connected to the upper end of the base plate 11. Connecting pipes 26 are sleeved inside the cooling fan 18, the LED light source body 19, and the fluid pump 25. The LED light source body 19 is sleeved inside the support box 17, and the convex mirror baffle 21 is slidably inserted into the support box 17. When facing different photocatalytic reaction requirements, different types of convex mirror baffles 21 can be replaced to change the light distribution, enhance the light intensity, and adjust the light spot shape. The cooling fan 18 and the support box 17 are set on the same horizontal line. The round rod 16 inside the rotating block 13 is engaged in the round groove opened inside the cooling fan 18 and the support box 17. The system is installed and fixed. A fluid pump 25 is installed on the upper end of the base plate 11. The support box 17, the cooling fan 18, and the fluid pump 25 are connected through the connecting pipe 26 to form a fluid circuit. The fluid pump 25 draws the fluid medium from the low-pressure area and pushes it to the high-pressure area through the flow force, so that the fluid medium circulates in the fluid circuit. The fluid medium exchanges heat with the room temperature air through the connecting pipe 26. When the fluid medium flows through the air outlet of the cooling fan 18, the air inlet of the cooling fan 18 is facing the support box 17 and the air outlet is facing the connecting pipe 26. When the fluid medium flows through the air outlet of the cooling fan 18, the rotating fan blades inside the cooling fan 18 can carry away the heat in the fluid medium, further improving the heat dissipation effect. By installing the base plate 11 in the scene required for the photocatalytic reaction, the LED light source body 19 installed on the upper end of the base plate 11 directly converts electrical energy into light energy and emits light signals to irradiate the reaction medium, so that the photocatalytic reaction can proceed normally.

[0031] A dovetail block 27 is fixedly connected to the lower end of the base plate 11. When changing different convex mirror baffles 21 to meet different photocatalytic reaction requirements, the convex mirror baffle 21 is pulled upwards. When the convex mirror baffle 21 slides, it will press the inclined surface of the locking block 24 through the inclined surface of the slot 22 opened inside it. At this time, the locking block 24 slides towards the side close to the spring 23 and presses the spring 23 into a contracted state. When changing to a different type of convex mirror baffle 21, it is aligned with the sliding groove opened in the support box 17 and inserted into it. The weight of the convex mirror baffle 21 is... Repeat the above operation to compress the spring 23 and the locking block 24. When the convex mirror baffle 21 contacts the bottom of the slide groove of the support box 17, the locking groove 22 and the locking block 24 are on the same horizontal line. At this time, under the reset force of the spring 23, the locking block 24 is driven to engage in the locking groove 22 to limit its position and ensure its stability. When installing the base plate 11 as a whole, the dovetail block 27 installed at the lower end of the base plate 11 can be aligned with the dovetail groove opened in the photocatalytic reaction device to achieve quick positioning and improve the installation stability.

[0032] To address the problems existing in the prior art, this utility model provides an LED light source for photocatalytic reactions. A circular rod 16 installed inside the rotating block 13 is inserted into a circular groove in the support box 17 and the cooling fan 18, allowing the cooling fan 18 and the LED light source body 19 to be uniformly mounted on the upper end of the base plate 11. During installation, the base plate 11 is directly installed in the photocatalytic reaction stage, achieving a rapid installation effect. Furthermore, all components are arranged on the same plane, reducing the space occupied by the device in different directions and making the overall structure more compact. This more compact installation layout allows the cooling fan 18, fluid pump 25, and connecting pipe 26 to cool the LED light source body 19 more closely, enhancing the heat dissipation effect and ensuring the stable operation of the LED light source body 19.

[0033] Working principle:

[0034] First, fit the LED light source body 19 into the support box 17, and slide the convex lens baffle 21 into the support box 17. To meet different photocatalytic reaction requirements, different types of convex lens baffles 21 can be used to change the light distribution, enhance the light intensity, and adjust the light spot shape. Set the cooling fan 18 and the support box 17 on the same horizontal line, and engage the rotating block 13 with the round rod 16 within the round grooves opened in the cooling fan 18 and the support box 17 (as per the instruction manual). Figure 5As shown in the diagram, the base plate 11 is installed and fixed. A fluid pump 25 is installed on the upper end of the base plate 11. The support box 17, the cooling fan 18, and the fluid pump 25 are connected through the connecting pipe 26 to form a fluid circuit. The fluid pump 25 draws the fluid medium from the low-pressure area and pushes it to the high-pressure area through the flow force, so that the fluid medium circulates in the fluid circuit. The fluid medium exchanges heat with the room temperature air through the connecting pipe 26. When the fluid medium flows through the air outlet of the cooling fan 18, the air inlet of the cooling fan 18 faces the support box 17 and the air outlet faces the connecting pipe 26. When the fluid medium flows through the air outlet of the cooling fan 18, the rotating blades inside the cooling fan 18 can carry away the heat in the fluid medium, further improving the heat dissipation effect. By installing the base plate 11 in the scene required for the photocatalytic reaction, the LED light source body 19 installed on the upper end of the base plate 11 directly converts electrical energy into light energy and emits light signals to irradiate the reaction medium, so that the photocatalytic reaction can proceed normally.

[0035] The second step, during installation, involves holding the rotating block 13 and screwing it towards the end near the limiting rod 15. At this point, the limiting rod 15 and the rectangular groove 14 inside the rotating block 13 are on the same horizontal line. The rotating block 13 is then screwed until it fits against the surface of the mounting base 12. Next, the limiting rod 15 is held and screwed 90 degrees. The lower end of the limiting rod 15 is a threaded rod, threaded into the mounting base 12. During rotation, the limiting rod 15 slides downwards and fits against the surface of the rotating block 13. The surface of the limiting rod 15 is cuboid in shape. The limiting rod 15 limits and fixes the rotating block 13. The round rod 16 installed inside the rotating block 13 is then inserted into the support box 17. The cooling fan 18 and the LED light source body 19 are uniformly installed on the upper part of the base plate 11 in the circular groove inside the cooling fan 18. During installation, the base plate 11 is directly installed in the photocatalytic reaction stage, achieving a quick installation effect. Moreover, all components are arranged on the same plane, reducing the space occupied by the device in different directions and making the overall structure more compact. The more compact installation layout allows the components to be closer together for heat dissipation of the LED light source body 19, enhancing the heat dissipation effect and ensuring the stable operation of the LED light source body 19. The support box 17 and the cooling fan can be installed by turning the limit rod 15 to adjust the installation direction and then turning the rotating block 13. The installation of the 18 is simple and convenient, saving installation time and improving overall installation efficiency. When changing different convex lens baffles 21 to meet different photocatalytic reaction requirements, pull the convex lens baffle 21 upwards. When the convex lens baffle 21 slides, it will press the inclined surface of the locking block 24 through the inclined surface of the slot 22 inside. At this time, the locking block 24 slides towards the side close to the spring 23, and presses the spring 23 into a contracted state. Different types of convex lens baffles 21 can be replaced (such as graded refractive index convex lens plate: its refractive index gradually changes from the center to the edge, which can more effectively control the propagation and focusing of light; biconvex lens plate: both sides are convex). (Compared to plano-convex mirrors, it has a stronger ability to converge light, etc.) Align it with the groove opened in the support box 17 and insert it into it. The convex mirror baffle 21 repeats the above operation to compress the spring 23 and the locking block 24 to retract. When the convex mirror baffle 21 contacts the bottom of the groove in the support box 17, the locking groove 22 and the locking block 24 are on the same horizontal line. At this time, under the reset force of the spring 23, the locking block 24 is driven to engage in the locking groove 22 to limit its position and ensure its stability. When installing the base plate 11 as a whole, the dovetail block 27 installed at the lower end of the base plate 11 can be aligned with the dovetail groove opened in the photocatalytic reaction device to achieve quick positioning and improve the installation stability.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
