Description

Technical Field

[0001] This invention belongs to the technical field of array light sources, specifically relating to a ring array light source for microbial detection. Background Technology

[0002] With the rapid advancement of urbanization, urban sewage discharge is continuously increasing, placing an increasingly heavy operational burden on sewage treatment plants. Currently, the activated sludge process is the mainstream technology for urban sewage treatment. Its core mechanism relies on the physical, chemical, and biological reactions triggered by various microorganisms in the sewage to effectively remove organic matter. Given that the main component of the activated sludge system is a microbial community, the diversity and richness of microbial species become key indicators for measuring sewage treatment efficiency. The growth status of different microbial populations directly determines the final sewage purification effect. In the specific operation of the activated sludge process, accurate detection of microorganisms in phase-contrast micrographs of activated sludge is not only a core element in ensuring the effectiveness of the activated sludge sewage treatment method, but also of immeasurable importance for real-time monitoring of the sewage treatment system's operation, promoting the sustainable development of the sewage treatment industry, and strengthening environmental protection efforts.

[0003] In existing technologies, when photographing microorganisms in wastewater using visual inspection devices, different wavelengths of light are needed to illuminate the microorganisms in the wastewater to ensure imaging quality and clear differentiation of different microorganisms in subsequent images. This allows different microorganisms to produce different photon effects under different wavelengths of light. However, traditional microbial light sources typically use linear arrays of light sources, with light distributed linearly. To ensure light intensity, several illumination units need to be closely arranged. This results in a large amount of heat being generated when a large number of illumination units are operating, affecting the normal operation of the light source. Furthermore, traditional linear array light sources directly illuminate the wastewater, and the beam angle is unconstrained, leading to localized areas of unclear microbial images in the final captured images.

[0004] Therefore, in view of the above-mentioned problems of existing array light sources used for microbial detection in sewage treatment, this utility model discloses a ring array light source for microbial detection. Utility Model Content

[0005] This invention discloses a ring array light source for microbial detection, which uniformly irradiates organisms in sewage at a specific beam angle in a ring arrangement, and can effectively reduce the operating temperature of the densely arranged light source.

[0006] This utility model is achieved through the following technical solution:

[0007] A ring array light source for microbial detection includes a substrate. Several integrated light sources are arranged along ring paths of different diameters on one side of the substrate. The integrated light sources can emit different wavelength ranges and different polychromatic lights. A transparent ring cover is arranged around the integrated light sources along the ring paths. A soft light TIR lens is arranged on the transparent ring cover at the position corresponding to the integrated light source. A water-cooling plate is arranged on the other side of the substrate. A heat transfer element is arranged around the integrated light sources and is connected to the water-cooling plate.

[0008] A ring array light source structure is formed by arranging several integrated light sources along annular paths of different diameters on one end face of a substrate. These integrated light sources can emit different wavelength ranges and various colors of light, enabling multi-color gamut illumination of organisms in wastewater within the visible spectrum. This allows different microorganisms to generate photon effects on optical fibers of different wavelengths, which can then be combined with a visual inspection system to photograph the microorganisms and analyze the wastewater treatment status. Simultaneously, a transparent TIR lens is used to correct the light emitted by the integrated light sources, ensuring that the emitted optical fibers illuminate at a specific diffusion angle. Because the integrated light sources in the ring array are relatively concentrated, they accumulate heat. Therefore, heat transfer components are placed around the integrated light sources to transfer the heat generated by the integrated light sources to a water-cooling plate. The water-cooling plate dissipates heat from the integrated light sources through water cooling, preventing the integrated light sources from overheating.

[0009] To better realize this utility model, further, an annular groove is provided on one side end face of the substrate along annular paths of different diameters, and a transparent annular cover is fitted at the opening of the annular groove.

[0010] To better realize this utility model, further, a number of mounting slots are evenly distributed and spaced inside the annular groove, an integrated light source is installed inside the mounting slot, and a TIR lens is fitted at the opening of the mounting slot.

[0011] To better realize this utility model, a supplementary lighting strip is further provided between adjacent annular grooves.

[0012] To better realize this utility model, the integrated light source further includes at least four of the following: ultraviolet light source, violet light source, blue light source, green light source, yellow light source, orange light source, red light source, and near-infrared light source; the wavelength of the ultraviolet light source is 190-380nm, the wavelength of the violet light source is 380-450nm, the wavelength of the blue light source is 450-490nm, the wavelength of the green light source is 490-570nm, the wavelength of the yellow light source is 570-590nm, the wavelength of the orange light source is 590-620nm, the wavelength of the red light source is 620-780nm, and the wavelength of the near-infrared light source is 780-1100nm.

[0013] To better realize this utility model, the beam angle of the soft light TIR lens is further 8-25°.

[0014] To better realize this utility model, the heat transfer element further includes a heat transfer plate and a circulation pipe. The heat transfer plate is arranged around the integrated light source, and the circulation pipe passes through the heat transfer plate in sequence and is connected to the water cooling plate.

[0015] To better realize this utility model, the water cooling plate is further provided with a water cooling cavity inside, and the water cooling cavity is connected to the circulation pipeline.

[0016] To better realize this utility model, the heat transfer sheet is further made of any one of copper sheet, silicone sheet, and graphite sheet.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] (1) The present invention provides an integrated light source along annular paths of different diameters on one side end face of the substrate, and emits different wavelength ranges and different polychromatic lights to the water in an annular irradiation manner. Furthermore, a soft light TIR lens is provided at the light-emitting end of the integrated light source, which can effectively adjust the light path so that the light emitted by the integrated light source can uniformly irradiate microorganisms with a specific beam angle, effectively preventing uneven light intensity distribution and glare, thereby ensuring the clarity and resolution of the final image of the microorganisms.

[0019] (2) This utility model provides a heat transfer component connected to the water cooling plate around the integrated light source. The heat transfer component can quickly transfer the heat emitted by the densely arranged integrated light source to the water cooling plate, thereby achieving heat dissipation of the integrated light source and effectively avoiding the problem of excessive temperature of the integrated light source.

[0020] (3) The present invention provides supplementary light strips between adjacent annular grooves. When the illumination light intensity is insufficient, the supplementary light strips can assist the integrated light source to supplement the light, thereby ensuring the light intensity requirements for photographing microorganisms.

[0029] Example 1:

[0030] This embodiment presents a ring array light source for microbial detection, such as... Figures 1-6 As shown, the system includes a substrate 1. Several integrated light sources 2 are arranged along annular paths of different diameters on one side of the substrate 1. The integrated light sources 2 can emit different wavelength ranges and different multicolor lights. A transparent annular cover 3 is arranged around the integrated light sources 2 along the annular path. A soft light TIR lens 4 is arranged on the transparent annular cover 3 at the position corresponding to the integrated light source 2. A water-cooling plate 5 is arranged on the other side of the substrate 1. A heat transfer element 6 is arranged around the integrated light sources 2 and is connected to the water-cooling plate 5.

[0031] The substrate 1 is provided with contacts that connect to the integrated light source 2, ensuring that the integrated light source 2 can be connected to an external LED driving circuit after being installed inside the transparent annular cover 3. The external LED driving circuit controls the on / off state and brightness of the integrated light source 2. The external LED driving circuit uses existing circuits and is not a technical improvement of this utility model, so its specific circuit structure and operating principle will not be described in detail here.

[0032] The transparent annular cover 3 has openings for mounting a soft-light TIR lens 4. The soft-light TIR lens 4 corrects the light emitted by the integrated light source 2, ensuring that the light emitted by the integrated light source 2 emits light at a specific angle, so that the light can be focused on a suitable area for illumination, ensuring the brightness and uniformity of the light, and thus ensuring the subsequent imaging effect of microorganisms. Since many integrated light sources 2 are relatively concentrated on the substrate 1, the integrated light sources 2 will generate a lot of heat when working together. In order to prevent the integrated light sources 2 from affecting their working state due to overheating, a heat transfer element 6 is arranged around the integrated light sources 2. Through heat transfer element 6, the heat emitted by the integrated light sources 2 is transferred to the water cooling plate 5, and heat is exchanged with the coolant in the cavity inside the water cooling plate 5, effectively controlling the temperature of the integrated light sources 2 to maintain it within a suitable temperature range.

[0033] Furthermore, the soft-light TIR lens 4 is of the -SS grade, with a beam angle of 8-25°. The surface of the -SS grade TIR lens has been treated with a soft-light coating, thereby achieving better light quality distribution, a wider beam angle, and the ability to illuminate more areas.

[0034] Example 2:

[0035] This embodiment discloses a ring array light source for microbial detection, which is further optimized based on the above embodiment 1 or 2, such as... Figure 1 and Figure 4 As shown, annular grooves 7 with different diameters are provided on one side end face of the substrate 1, and a transparent annular cover 3 is fitted at the opening of the annular groove 7. The transparent annular cover 3 is made of transparent glass and is directly fitted at the opening of the annular groove 7 to protect the integrated light source 2 inside the annular groove 7.

[0036] Furthermore, such as Figure 4 As shown, the annular groove 7 has several mounting slots 8 evenly spaced inside. An integrated light source 2 is installed inside each mounting slot 8, and a TIR lens 4 is fitted into the opening of each mounting slot 8. The mounting slot 8 has an internal thread, and the connecting end of the integrated light source 2 is connected to the corresponding internal thread, which facilitates the convenient installation of the integrated light source 2 inside the mounting slot 8 and also facilitates the convenient replacement of the integrated light source 2.

[0037] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.

[0038] Example 3:

[0039] This embodiment discloses a ring array light source for microbial detection, which is further optimized based on the above embodiment 1, such as... Figure 3 As shown, supplementary lighting strips 9 are provided between adjacent annular grooves 7. When the illumination light is insufficient, the supplementary lighting strips 9 are turned on to supplement the integrated light source 2, ensuring the brightness for photographing microorganisms.

[0040] The supplementary light strip 9 uses white LED light strips. The supplementary light strip 9 is connected to an external LED driving circuit through the substrate 1 to control the on / off state and brightness of the supplementary light strip 9.

[0041] The other parts of this embodiment are the same as those in Embodiment 1 or 2 above, so they will not be described again.

[0042] Example 4:

[0043] This embodiment discloses a ring array light source for microbial detection, which is further optimized based on any one of embodiments 1-3 above. The integrated light source 2 includes at least four of the following: ultraviolet light source, violet light source, blue light source, green light source, yellow light source, orange light source, red light source, and near-infrared light source. The wavelength of the ultraviolet light source is 190-380nm, the wavelength of the violet light source is 380-450nm, the wavelength of the blue light source is 450-490nm, the wavelength of the green light source is 490-570nm, the wavelength of the yellow light source is 570-590nm, the wavelength of the orange light source is 590-620nm, the wavelength of the red light source is 620-780nm, and the wavelength of the near-infrared light source is 780-1100nm.

[0044] Preferably, the ultraviolet light source includes a UVA ultraviolet light source, a UVB ultraviolet light source, and a UVC ultraviolet light source, wherein the wavelength of the UVA ultraviolet light source is 315-380nm, the wavelength of the UVB ultraviolet light source is 280-315nm, and the wavelength of the UVC ultraviolet light source is 190-280nm.

[0045] The integrated light source 2 adjusts the light intensity from 0 to 100% through an external LED driving circuit. By setting the four wavelengths of light mentioned above, it can form a wide color gamut light output covering the visible spectrum.

[0046] Depending on actual usage requirements, the integrated light source 2 is not limited to the four wavelengths of light mentioned above.

The heat transfer plate 61 is arranged around the integrated light source 2, and the circulation pipe 62 passes through the heat transfer plate 61 in sequence and is connected to the water cooling plate 5.

[0050] By arranging heat transfer plates 61 around the integrated light source 2, the heat transfer area can be increased, thereby improving the heat dissipation efficiency of the integrated light source 2. Heat is transferred to the circulation pipe 62 through the heat transfer plates 61. Coolant from inside the water cooling plate 5 circulates in the circulation pipe 62, and the circulating coolant can quickly remove the heat from the heat transfer plates 61.

[0051] Furthermore, the water-cooling plate 5 is provided with a water-cooling cavity inside, and the water-cooling cavity is connected to the circulation pipe 62.

[0052] Furthermore, the heat transfer plate 61 can be any one of copper plate, silicone plate, or graphite plate.

[0053] The other parts of this embodiment are the same as any one of the embodiments 1-4 above, so they will not be described again.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
