Description

Technical Field

[0001] This utility model relates to the fields of photocatalysis and photothermal catalysis, and in particular to an ambient light source. Background Technology

[0002] In research fields such as photocatalysis and photochemical synthesis, annular light sources are typically used to provide uniform and efficient illumination of materials within tubular reactors. Annular light sources, by surrounding the tubular reactor with multiple light source units, can irradiate the reactor from multiple angles, thereby improving the uniformity of illumination and energy utilization.

[0003] Existing technologies, such as traditional ring-shaped light sources, suffer from the following problems: 1. They have a large emission angle, making them suitable for reactors with larger diameters, resulting in a small length-to-diameter ratio; 2. Due to the large angle and diameter, the light power density is relatively low, and the end loss is significant; 3. Common ring-shaped light sources employ an integrated or fixed annular structure that completely encloses the tubular reactor. While this design creates a closed lighting environment, it also brings significant operational inconvenience. When it is necessary to replace, clean, or remove the tubular reactor, operators must disassemble the entire light source device or laboriously insert or remove the reactor from one end of the annular structure. This is not only time-consuming and labor-intensive but also greatly reduces experimental efficiency.

[0004] In addition, existing ambient light sources generally suffer from other problems. For example, in pursuit of high-power irradiation, the light source generates a large amount of heat, while traditional air-cooling methods are usually bulky and noisy, limiting the miniaturization and integration of the entire device. At the same time, if the optical design is poor, the light emitted by the light source cannot be efficiently focused onto the tubular reactor, resulting in a large amount of light energy loss and waste, as well as uneven irradiation, which in turn affects the accuracy and reproducibility of the reaction results. Utility Model Content

[0005] The purpose of this invention is to provide a surround-illuminated light source that solves the technical problems of existing technologies, such as being suitable only for reactors with larger diameters, having low light power density, fixed structure, and inconvenience in handling reactors. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a surround-type light source, including light source modules and hinges. The light source modules are multiple and together enclose a central space for accommodating a tubular reactor. The hinges are disposed between adjacent light source modules, so that at least one light source module can open and close relative to another light source module to open the central space.

[0007] Preferably, the light source module and the reflector are arranged sequentially at intervals.

[0008] Preferably, the reflector is an arc-shaped reflector.

[0009] Preferably, the light source module includes a mounting base, an LED bead, a lens, and a lampshade. The mounting base has an installation space, the LED bead is disposed within the installation space, the lampshade is disposed on the mounting base, the lens is disposed within the lampshade and is located in the light emission path of the LED bead, and the lampshade has a light emission port.

[0010] Preferably, the LED beads are evenly arranged along the length of the light source module, and the lens is a cylindrical body that extends along the entire length of the light source module.

[0011] Preferably, it further includes a liquid cooling structure disposed on the light source module for dissipating heat from the light source module.

[0012] Preferably, the light source modules are arranged in a circular array.

[0013] Preferably, it also includes a light source base, and at least one of the light source modules is disposed on the light source base.

[0014] Preferably, the light source base is arc-shaped, and the light source module includes a fixed light source module disposed on the light source base and two openable light source modules, both of which are hinged to both ends of the light source base by the hinge.

[0015] The application employs the above technical solution and has at least the following beneficial effects: By incorporating hinges, at least one pair of adjacent light source modules can be opened and closed, achieving a closable structure for the light source device. Users can easily open the light source modules to directly insert or remove the tubular reactor into the central space, greatly simplifying the operation process, improving experimental efficiency, and solving the problem of difficult reactor placement and removal in existing technologies. The light source modules utilize liquid cooling, resulting in higher heat dissipation efficiency, allowing the light source to operate stably at high power, extending its lifespan, while simultaneously reducing the size of the heat dissipation system, making the entire device more compact. By incorporating lenses within the light source modules to shape and focus the beam, combined with reflectors to recover and utilize stray light, the irradiance energy density and uniformity reaching the surface of the tubular reactor are significantly improved, ensuring the uniformity and efficiency of the photochemical reaction. The lens-based beam shaping and focusing allows this light source module to be adapted to reactors with larger aspect ratios. Furthermore, the reflectors, while reflecting light, also provide some heat insulation and light blocking, improving safety.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This embodiment provides an ambient light source, which aims to solve the problems inherent in the ambient light source of the prior art, such as large reactor diameter, small length-to-diameter ratio, low light power density, fixed structure, inconvenient reactor placement and removal, large size, low heat dissipation efficiency and low light energy utilization.

[0022] like Figure 1As shown, the ring-shaped light source of this embodiment forms an openable and closable annular structure. The device includes multiple light source modules 1 arranged in an array along the circumference. In this embodiment, three identical light source modules 1 are specifically shown. These three light source modules 1 together enclose a central space, which is used to accommodate a tubular reactor (not shown in the figure), such as a quartz tubular photocatalytic reactor. When the device is in... Figure 1 In the closed state shown, the three light source modules 1 form a ring-shaped irradiation cavity. This structure can concentrate light energy onto the tubular reactor in the central space, thereby significantly improving energy utilization.

[0023] To enable the device to be opened and closed, facilitating the installation and removal of the tubular reactor, a hinge 2 is provided between adjacent light source modules 1. Specifically, as... Figure 1 and Figure 2 As shown, the hinge 2 can be a hinge structure. For example... Figure 2 As shown, the two movable light source modules 1 can be rotated outward around the hinge axis to fully open the central space. This allows researchers to easily place or remove the tubular reactor directly from above. After the operation is complete, the two movable light source modules 1 can be rotated inward to close the reactor. This opening and closing structure simplifies the process of placing and removing the tubular reactor, improving the convenience and efficiency of operation.

[0024] To cope with the enormous heat generated by high-power light sources during operation, ensure the stability and lifespan of the light source, and achieve device miniaturization, this embodiment employs a liquid cooling structure. For example... Figure 1 and Figure 2 As shown, each light source module 1 integrates a liquid cooling structure 3 on its housing. This liquid cooling structure 3 dissipates heat and controls the temperature of the light-emitting element inside the light source module. It should be noted that the liquid cooling structure 3 has a precisely designed coolant flow channel (e.g., a serpentine or parallel microchannel), and each light source module 1 has an interface on its exterior for connecting to an external cooling circulation system, such as an inlet and an outlet. In use, external coolant (e.g., deionized water or ethylene glycol aqueous solution) is connected to the above interface via pipes and circulates within the internal flow channel of the liquid cooling structure 3 under the drive of a cooling pump, thereby efficiently absorbing and carrying away the heat generated by the light-emitting element. The liquid cooling structure 3 can be made of a metal with excellent thermal conductivity, such as copper or aluminum alloy, to ensure that heat can be rapidly conducted from the light-emitting element to the coolant. Through this design, even when the light-emitting element operates at a high power of several hundred watts, its temperature can be precisely controlled within a safe range. This not only ensures the stability of light output and the long-term reliability of the device, but also results in a volume much smaller than a forced air cooling system with equivalent heat dissipation capacity, thus achieving a compact design for the entire ambient light source.

[0025] To achieve efficient and uniform irradiation of the tubular reactor, each light source module 1 contains an optimized optical system. Please refer to [link / reference]. Figure 3 and attached Figure 4 The light source module 1 includes a mounting base 5, LED chips 6, a lens 7, and a lampshade 8. The mounting base 5 has a mounting space 9, the LED chips 6 are disposed within the mounting space 9, the lampshade 8 is mounted on the mounting base 5, the lens 7 is disposed within the lampshade 8 and is located on the light emission path of the light-emitting element, and the lampshade 8 has a light emission port 10. In one embodiment of this application, to achieve uniform illumination along the entire axial length of the tubular reactor, multiple high-power LED chips can be linearly arranged along the length direction of the light source module 1, and these chips can be packaged on the same substrate to form a strip-shaped LED chip. Accordingly, the LED chips are mounted on a substrate (e.g., a metal core printed circuit board with high thermal conductivity) that is tightly attached to the liquid cooling structure 3 to achieve efficient heat transfer.

[0026] A lens 7 for beam shaping and focusing is provided along the light emission path of the LED 6. In this embodiment, the lens 7 is specifically a cylindrical lens, but other lens structures can also be used. Its purpose is to improve the overall irradiance energy density of the light source, as well as improve irradiance uniformity and collimation, adapting to reactors with a larger aspect ratio. The length of the cylindrical lens roughly matches the length of the light-emitting area of ​​the LED 6 and extends along the length of the light source module 1. It can be understood that the shaping process of the cylindrical lens essentially utilizes its unidirectional optical power to converge the light beam in one direction (curvature direction) while maintaining the light propagation direction unchanged in the other perpendicular direction (no curvature direction). When the light emitted by the LED 6 passes through the cylindrical lens, it is focused and shaped into a narrow strip of light. Since the three light source modules 1 surround the central tubular reactor, the strip of light generated by each light source module is projected onto the outer surface of the reactor tube wall, and the length direction of the light spot is parallel to the axial direction of the reactor. The superposition of three strip-shaped light spots can form a very uniform irradiance distribution along the entire circumference and axial length of the tubular reactor, which significantly improves the utilization efficiency of light energy and the uniformity of photochemical reactions. After being shaped, the light rays are directed into the central space through the light outlet 10 on the light source module 1.

[0027] To further capture and utilize stray light emitted from the light source but not directly absorbed by the tubular reactor, the device of this application also includes a reflector. For example... Figure 1 and Figure 2As shown, a reflector 4 is installed on the inner wall enclosed by the three light source modules 1. This reflector 4 has extremely high reflectivity (e.g., greater than 95%), and its shape is an arc matching the inner contour of the light source module 1. When some of the light emitted by the lamp beads 6, or light reflected from the reactor surface, shines on the reflector 4, it is reflected back into the central space and re-acts on the tubular reactor. This design constitutes a highly efficient light trap, minimizing light energy loss and further improving the overall energy efficiency of the device. In addition, the reflector 4 also provides some heat insulation and light blocking, protecting the outer casing and experimental personnel from the direct effects of high temperatures and strong light, thus enhancing operational safety.

[0028] In summary, the surround-illuminated light source disclosed in this embodiment connects multiple light source modules 1 using hinges or other connecting components 2, enabling convenient opening and closing of the device. Simultaneously, the device integrates a liquid cooling structure 3 thermally coupled to the LED beads 6, achieving efficient and compact heat dissipation. In terms of optical design, the LED beads 6 inside each light source module cooperate with cylindrical lenses to precisely control the light beam to form a uniform stripe-shaped light spot, while the reflectors 4 on the inner wall further recover dissipated light energy. The synergistic effect of these structural features gives this device the advantages of convenient operation, compact structure, efficient heat dissipation, high light energy utilization, and uniform irradiation.

[0029] In some embodiments, the hinge 2 may also employ a more robust and durable hinge structure. These hinges are typically more complex and robust than ordinary hinges, capable of withstanding greater loads and providing a smoother rotation experience, suitable for larger or heavier light source modules 1. For example, industrial-grade precision hinges may be used, which may contain ball bearings or self-lubricating bushings to reduce friction and ensure stability and accuracy over long-term use.

[0030] In some embodiments, the hinge 2 may also adopt a door hinge structure or a pin connection structure, etc.

[0031] It is understood that, regardless of whether hinges, pivots, or pins are used, the above structures are all designed to provide a stable axis of rotation, enabling at least one light source module 1 to pivot relative to another light source module 1, thereby opening and closing the central space. Therefore, these specific mechanical structures can all serve as specific implementations of the "hinge 2" disclosed in this application, indicating that there are various means to achieve this pivoting function, and it should not be limited to the specific structure shown in Embodiment 1.

[0032] In some embodiments, the reflector 4 may also employ a flexible reflective film. This type of reflective film typically consists of a polymer substrate (such as polyethylene terephthalate) and a reflective layer with a vacuum-plated aluminum or silver coating, and is characterized by its thinness and flexibility. In use, this flexible reflective film with adhesive backing can be directly adhered to the inner curved surface of the three light source modules 1. The advantages of this solution are low cost, easy installation, and good adaptability to various complex curved surfaces. Replacement is also relatively easy if the reflective film surface becomes contaminated or scratched due to long-term use.

[0033] As an alternative implementation, the reflector 4 can be a separate, detachable component. For example, a single piece of high-reflectivity aluminum or stainless steel plate can be processed into a cylindrical or polygonal structure with an axial opening, i.e., an open reflector tube. In use, the three light source modules 1 are first closed, and then this independent reflector tube is inserted from above, ensuring that its inner wall is tightly against the inner side of the three light source modules 1, and that light can pass through the axial opening and be projected inward. The advantage of this design is that the reflector is separate from the light source modules, facilitating cleaning and replacement. Furthermore, reflector tubes with different surface properties (such as specular reflection or diffuse reflection) can be easily replaced according to different experimental needs to adjust the light field distribution in the central space.

[0034] In addition, the reflector 4 can also be formed by directly surface treating the inner wall of the light source module 1. For example, the metal parts constituting the inner wall of the light source module (such as the inner surface of the light source base 11) can be highly polished and electroplated (such as chrome plating or silver plating) or physically vapor deposited to form a high-reflectivity metal film, thereby giving it excellent reflective function.

[0035] In summary, whether it is a fixed reflector 4, a flexible reflective film, an independent reflective cylinder, or a reflective coating formed directly on the surface of the component, their function is to reflect stray light back into the central space to improve light energy utilization. Therefore, these different technical solutions can all be regarded as optional implementations of the technical feature of "reflector" in this application, reflecting the diversity of this feature in terms of materials, shapes, and installation methods.

[0036] In some embodiments, the light source base 11 is also included, and at least one light source module 1 is disposed on the light source base 11. Specifically, the light source base 11 can be designed to be arc-shaped, and one of the light source modules 1 is disposed on the light source base 11 in a fixed manner. Hinges 2 are respectively provided at both ends of the light source base 11, and the openable light source module 1 is hinged by the hinges 2.
