Abstract
Description
Technical Field
[0001] This invention relates to the field of ultraviolet light application technology, and in particular to a UVA LED light source module and a photocatalytic honeycomb aluminum plate purification module. Background Technology
[0002] Photocatalysts (such as TiO2) can generate strong oxidizing substances when excited by ultraviolet light at specific wavelengths (especially around 365nm), which can be used to decompose organic pollutants in the air. Coating photocatalysts onto honeycomb aluminum panels to form purification modules with a large specific surface area is one of the mainstream solutions for industrial air purification.
[0003] Currently, there are two main methods for providing ultraviolet light sources to honeycomb aluminum panels: external mercury lamps or LED tubes and simple built-in LED light panels. External mercury lamps or LED tubes, with their light source independent of the honeycomb panel, suffer from uneven illumination, low light energy utilization, large space requirements, and the risk of contamination from lamp breakage. Simple built-in LED light panels, on the other hand, place ordinary LED panels on one side or inside the honeycomb panel. The light panel itself can severely block the honeycomb channels, affecting ventilation, increasing fan energy consumption, and the dense light source causes heat to accumulate in the enclosed space, leading to accelerated LED light decay and shortened lifespan. Furthermore, the arrangement of the LED beads and the emission angle are not optimized for the deep pores of the honeycomb structure, resulting in weak illumination intensity deep within the channels and incomplete photocatalytic excitation.
[0004] Therefore, there is an urgent need for a dedicated ultraviolet light source that can be highly integrated with photocatalytic honeycomb aluminum panels, has low wind resistance, high uniformity, and good heat dissipation to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide an ultraviolet light source module for photocatalytic honeycomb aluminum panel purification, which aims to achieve high-intensity uniform irradiation while minimizing obstruction of the airflow channel and ensuring thermal stability during long-term operation.
[0006] To solve the above problems, the present invention provides,
[0007] On the one hand, a UVA LED light source module includes,
[0008] substrate,
[0009] UVA LED light source, wherein the UVA LED light source array is distributed on the substrate;
[0010] The substrate has a first hollow area, and the first hollow area and the UVA LED light source are arranged alternately in the horizontal direction on the substrate.
[0011] The substrate has a second cutout area, and the second cutout area and the UVA LED light source are arranged alternately in the longitudinal direction on the substrate;
[0012] The area of the second hollow area is larger than that of the first hollow area.
[0013] Furthermore, the emission half-angle of the UVA LED light source is 45°±15°;
[0014] Furthermore, the width of the first hollow area is 3mm-5mm, and the length is 13mm-18mm.
[0015] Furthermore, the distance between the centers of the two UVA LED light sources is 18mm-25mm.
[0016] On the other hand, a photocatalytic honeycomb aluminum panel purification module.

[0019] Its features are,

[0021] The substrate has a second hollow area, and the second hollow area and the UVA LED light source are arranged alternately in the longitudinal direction on the substrate; the area of the second hollow area is larger than that of the first hollow area;
[0022] The circuit bypasses the first and second cutout areas and connects the UVA LED light source electrically to ensure the integrity and reliability of the electrical connection.
[0023] A photocatalytic honeycomb aluminum plate, wherein the surface of the photocatalytic honeycomb aluminum plate is coated with a photocatalyst, and the photocatalytic honeycomb aluminum plate is overlapped with the substrate so that the UVA LED light source is uniformly irradiated onto the photocatalytic honeycomb aluminum plate.
[0024] Furthermore, the photocatalytic honeycomb aluminum plate includes
[0025] A bracket, one end of which is used for fixed connection with the substrate;
[0026] A honeycomb aluminum panel, which is fixedly connected to the other end of the bracket.
[0027] 7. A photocatalytic honeycomb aluminum plate purification module according to claim 5, characterized in that,
[0028] The UVA LED light source uses 3535-packaged LEDs.
[0029] Furthermore, the UVA LED light source has a emission half-angle of 45°±15°.
[0030] Furthermore, the spacing between the centers of the UVA LED light sources is preferably 18-25 mm.
[0031] Furthermore, the irradiation distance between the UVA LED light source beads and the honeycomb aluminum plate is preferably 15-25 mm.
[0032] Furthermore, the UVA LED light source is 365nm ultraviolet light.
[0033] The beneficial effects of this invention are that the first hollow area forms a mesh ventilation channel. This design greatly reduces airflow resistance while ensuring structural strength and circuit integrity. It also utilizes the heat conduction of the substrate and the airflow in the first and second hollow areas to achieve efficient heat dissipation. The module can be closely attached to the end face of the photocatalytic honeycomb aluminum plate, so that the UVA LED light source can uniformly irradiate the photocatalytic coating on the inner wall of the honeycomb aluminum plate pores at a wide angle, generating strong oxidizing substances to decompose organic pollutants in the air. This significantly improves excitation uniformity and purification efficiency, achieving integrated design with low wind resistance, high uniformity, and long lifespan. Attached Figure Description

[0040] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0041] Please see Figures 1 to 4 This invention provides a photocatalytic honeycomb aluminum plate purification module structure.
[0042] Substrate 1, which is made of a metal material, preferably aluminum;
[0043] The UVA LED light source 3 is arrayed on the substrate; the UVA LED light source 3 contains 4-15 LEDs in the horizontal direction and 2-15 rows in the vertical direction, with a total of 8-225 LEDs.
[0044] The substrate 1 is provided with a first hollow area 4, and the first hollow area 4 and the UVA LED light source 3 are arranged alternately in the horizontal direction on the substrate 1;
[0045] The substrate 1 has a second hollow area 7, and the second hollow area 7 and the UVA LED light source 3 are arranged alternately in the longitudinal direction on the substrate 1; the area of the second hollow area 7 is larger than that of the first hollow area 4.
[0046] Circuit 2, wherein the wiring of circuit 2 bypasses the first cutout area 4 and the second cutout area 7; and electrically connects the UVA LED light source 3;
[0047] A photocatalytic honeycomb aluminum plate 6 is provided, the surface of which is coated with a photocatalyst. The photocatalytic honeycomb aluminum plate 6 is overlapped with the substrate 1, so that the UVA LED light source 3 can uniformly irradiate the photocatalytic honeycomb aluminum plate 6.
[0048] The UVA LED light source 3 has a center wavelength of 365nm, a light emission half-angle of 30°-60° (preferably 30°), a spacing between the centers of the UVA LED light source beads of 18mm-25mm (preferably 21mm), a spacing between the UVA LED light source beads and the honeycomb aluminum plate of 15-25mm (preferably 21mm), and a honeycomb aluminum plate thickness of 5mm.
[0049] In this embodiment, the UVA LED light source 3 adopts a UVA LED light source with a specific emission half-angle of 30° and a spacing of 21mm. A mesh ventilation channel is formed in the first hollow area 4 with a=5mm, b=3.5mm, d=15mm, and e=3.5mm. This design greatly reduces airflow resistance while ensuring structural strength and circuit integrity. It also achieves efficient heat dissipation by utilizing the heat conduction of the first hollow area and the airflow of the second hollow area 7. The UVA LED light source 3 adopts a UVA LED light source with a specific emission half-angle of 30° and a lamp bead spacing of 21mm. This allows the ultraviolet light emitted by the UVA LED light source lamp beads to uniformly irradiate the photocatalytic coating on the inner wall of the 5mm thick honeycomb aluminum plate pores at a spacing of 21mm, generating a strong oxidizing substance to decompose organic pollutants in the air. This significantly improves excitation uniformity and purification efficiency, achieving integrated low wind resistance, high uniformity, and long lifespan.
[0050] Furthermore, the photocatalytic honeycomb aluminum plate 6 includes a support 5 and a honeycomb aluminum plate, one end of the support 5 is used to be fixedly connected to the substrate 1; the honeycomb aluminum plate is fixedly connected to the other end of the support 5.
[0051] Compared with existing technologies, this solution has the following outstanding advantages:
[0052] Revolutionary low-drag design: By setting a strip-shaped first hollow area 4 of a specific size on the hollow area, a direct channel for airflow is opened while ensuring the structural strength of the second hollow area 7. When the module is installed close to the photocatalytic honeycomb aluminum plate 6, the airflow can penetrate the first hollow area 4 and enter the honeycomb channel, reducing wind resistance by more than 30% and significantly reducing system energy consumption.
[0053] Excellent heat dissipation and light distribution:
[0054] Heat dissipation: The 2.1mm wide second hollow area itself has good thermal conductivity. Combined with the large LED bead spacing of 18-25mm and the airflow brought by the first hollow area 4, a dual high-efficiency heat dissipation mechanism of "conduction + convection" is formed, which greatly extends the life of LEDs.
[0055] Uniform light emission: A 30-60° emission half-angle is matched with an irradiation spacing of 15-25mm, allowing the light to cover the sidewalls of the honeycomb channels with a wider cone angle. For deep honeycomb structures, the wide emission angle combined with a reasonable spacing ensures uniform axial and radial irradiation from the opening to the bottom of the channel, resulting in uniform irradiation intensity and high photocatalyst utilization.
[0056] Significantly improved removal rate:
[0057] The low-resistance hollow design significantly improves the uniformity of airflow velocity in each small hole of the honeycomb aluminum panel, thereby increasing the photocatalytic efficiency by more than 30%.
[0058] High integration and flexibility:
[0059] The module has a flat structure and can be directly pasted or snapped onto the end face of the standard-sized photocatalytic honeycomb aluminum plate 6, realizing the integration of the light source and the reactor.
[0060] By selecting different matrix sizes (such as combinations of 4x2, 8x4, 12x12, etc.), honeycomb panels of various air volumes and purification specifications can be flexibly adapted to achieve modular assembly.
[0061] The above-disclosed embodiments are merely preferred embodiments of an ultraviolet light source module for photocatalytic honeycomb aluminum plate purification, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
