The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] In related technologies, with the development of LED and LD technology, especially in the application of medical and endoscopy fields, a wider range of light source options and higher flexibility are provided to meet different diagnostic and treatment needs. Multi-wavelength light source combinations can simulate white light or produce specific spectra, optimize tissue observation, and improve visual effects, such as helping to distinguish different tissue types, reduce damage, and enhance blood vessel clarity during endoscopic surgery.

[0047] In an endoscope system using LED or LD light sources, there are multiple light sources with different peak wavelengths (bands). By combining the light beams emitted by two or more light sources with different peak wavelengths (bands), a variety of illumination lights including white light can be obtained. Compared with the light beams emitted by a single wavelength light source, it can flexibly meet various diagnostic and treatment needs. For example, it is possible to flexibly select appropriate light combination according to the structural characteristics of the inner wall of the cavity, mucosa, blood vessels, etc., so as to obtain a high-contrast cavity image.

[0048] Therefore, in order to achieve diversified illumination light, it is expected that the endoscope system has more light sources. However, due to the geometric dimensions of the endoscope itself, especially the radial dimension of the insertion portion of the endoscope, the number of arranged light sources is limited.

[0049] like Figure 1 As shown, in order to solve the above technical problems, an embodiment of the present application provides an endoscope light source system, which includes a first light combining component 300 and a plurality of second light combining components 200. The first light combining component 300 has a first main light path 320 and a plurality of first sub-light paths 330. The first light combining component 300 can reflect a light beam propagating along the first sub-light path 330 to the first main light path 320. The first light combining component 300 can transmit a light beam propagating along the first main light path 320, and the plurality of first sub-light paths 330 are arranged along the first main light path 320. The optical path 320 is arranged at intervals in the extension direction; the second light combining component 200 has a second main optical path 210 and multiple second sub-optical paths 220, the second main optical path 210 of the second light combining component 200 coincides with the corresponding first sub-optical path 330, the second light combining component 200 can reflect the light beam propagating along the second sub-optical path 220 to the second main optical path 210, the second light combining component 200 can transmit the light beam propagating along the second main optical path 210, and the multiple second sub-optical paths 220 are arranged at intervals in the extension direction of the second main optical path 210.

[0050] This application integrates complex optical path management and beam control technologies to optimize light source efficiency and imaging quality. The system is mainly divided into two core parts, namely the first light combining component 300 and multiple second light combining components 200, each of which is carefully designed to achieve specific functions and work together to improve the light source utilization and imaging effect of the endoscope.

[0051] In simple terms, the first main optical path 320 of the first light combining component 300: serves as the main transmission channel of the light beam, connecting all the first sub-optical paths 330 to ensure the convergence and output of the light beam. Multiple first sub-optical paths 330 are arranged at intervals along the direction of the first main optical path 320, and these first sub-optical paths 330 are used to receive light beams from different wavelengths or light sources. Among them, the first light combining component 300 has a reflection mechanism: it is capable of reflecting the light beam propagating along the first sub-optical path 330 to the first main optical path 320, so as to realize the merging of multiple light beams; optionally, it is completed through a prism surface or a reflective lens.

[0052] The first light combining component 300 has transmission: it ensures the transmission of the light beam propagating along the first main light path 320, which means that the first main light path 320 can propagate the light beam, and is designed to reduce light loss to achieve light combining of multiple light beams.

[0053] The second light combining component 200 plays a synergistic role. The second main light path 210 of the second light combining component 200 matches the first sub-light path 330 of the first light combining component 300, ensuring the effective docking of the light beams between the two systems and realizing the integration of more light sources. In addition, the second sub-light path 220 also extends along the second main light path 210, corresponding to receiving another group of light sources or wavelengths of light beams, increasing the spectral coverage. Among them, the second light combining component 200 also reflects the light of the second sub-light path 220 to the second main light path 210 and transmits the light beam of the second main light path 210, so as to achieve the purpose of integrating the light beams.

[0054] Exemplarily, the second sub-optical paths 220 respectively input light beams of set wavelengths to ensure that the light beams of each second sub-optical path 220 can be reflected and transmitted, and thus matched with the first light combining component 300 and the second light combining component 200, and the light beams corresponding to each second sub-optical path 220 are different.

[0055] Optionally, to further increase the types of light beams, the beginning of the first main light path 320 and the beginning of the second main light path 210 can respectively receive light beams, thereby increasing the adjustable range of the endoscope light source system and facilitating reduction of the outer diameter of the endoscope.

[0056] From this, we can see that the overall system advantages include the following:

[0057] 1. Through the integration of the first main light path 320 and the first sub-light path 330, the second main light path 210 and the second sub-light path 220, efficient merging and distribution of light beams are achieved, and light energy is optimized to control different light sources, thereby improving brightness and color gamut;

[0058] 2. Design and divide the optical path layout to allow the system to adapt to a variety of light source wavelengths to meet different diagnosis and treatment needs, such as white light, special spectrum therapy, and imaging;

[0059] 3. Under the limitation of the radial size of the endoscope tube, the number and efficiency of light sources are maximized through fine layout, thus improving the performance of the endoscope light source system;

[0060] 4. Precisely control the light beam to reduce stray scattering and chromatic aberration, improve imaging clarity, facilitate diagnosis and treatment operations, and improve the quality of medical services.

[0061] In summary, the comprehensive design of this system embodies the refinement, integration, and efficient utilization of light source management, as well as its adaptability to the medical application environment, and is an important manifestation of the advancement of endoscopic technology.

[0062] like Figure 2 and Figure 3 As shown, in some embodiments, the first light combining component 300 includes a plurality of first light combining sheets 310, and the plurality of first light combining sheets 310 are arranged at intervals along the first main light path 320; wherein the first light combining sheet 310 can reflect the light beam propagating along the corresponding first sub-light path 330 to the first main light path 320; and the first light combining sheet 310 can transmit the light beam propagating along the first main light path 320.

[0063] In this embodiment, the first light combining sheet 310 adopts a multi-layer light sheet layout: multiple first light combining sheets 310 are arranged at intervals along the first main light path 320. This layout means that each first light combining sheet 310 is responsible for the light path control of a specific area, realizing the precise management of the light beam. Each first light combining sheet 310 plays a dual role, which can reflect the light beam from the specific first sub-light path 330 to the first main light path 320 to realize the merging of the light beams, and can also transmit the light beam propagating along the first main light path 320, ensuring that the light passes through the light combining smoothly and reducing light loss.

[0064] The first sub-optical path 330 is a branch used to carry light from different light sources or specific wavelengths, and is integrated with the first main optical path 320 to achieve diversity and efficient transmission of light beams. Through the precise design of the first light combining sheet 310, the light beam is effectively guided and converges from the first sub-optical path 330 to the first main optical path 320, while ensuring that the light beam of the first main optical path 320 is unobstructed, thereby optimizing the light transmission path.

[0065] As a result, the multi-layer first light-combining sheet 310 design can maximize the use of available space inside a limited space endoscope, integrate multiple light paths, do not increase the light source, and optimize the light source density. In addition, it ensures the directional transmission of the light beam, reduces scattering, enhances the isolation between light paths, improves the imaging clarity and contrast, and is suitable for diagnostic or therapeutic operations. In addition, the first sub-light path 330 can carry light of different wavelengths, and the design of the first light-combining sheet 310 enables the multi-wavelength light beams to be effectively merged, broadens the scope of application, and adapts to more medical spectral treatment needs.

[0066] For example, in the present embodiment, the number of the first light-combining sheets 310 is 2; of course, in other embodiments, the number of the first light-combining sheets 310 is 3, 4, 5, 6, 7, and so on.

[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the second light combining component 200 includes a plurality of second light combining plates 230, and the plurality of second light combining plates 230 are arranged at intervals along the second main light path 210; wherein the second light combining plates 230 can reflect the light beam propagating along the corresponding second sub-light path 220 to the second main light path 210; and the second light combining plates 230 can transmit the light beam propagating along the second main light path 210.

[0068] Similarly, in this embodiment, the second light combining sheet 230 adopts a multi-layer light sheet layout: multiple second light combining sheets 230 are arranged at intervals along the second main light path 210. This layout means that each second light combining sheet 230 is responsible for the light path control of a specific area, thereby achieving precise management of the light beam. Each second light combining sheet 230 plays a dual role, which can not only reflect the light beam from a specific second sub-light path 220 to the second main light path 210 to achieve the merging of the light beams, but also transmit the light beam propagating along the second main light path 210 to ensure that the light passes smoothly through the light combining and reduce light loss. Obviously, by cooperating with the second main light path 210 through the first main light path 320, the light combining of multiple light beams can be achieved, and the miniaturization of the outer diameter of the endoscope can be ensured.

[0069] Among them, the second sub-optical path 220 is a branch used to carry light from different light sources or specific wavelengths, and is integrated with the second main optical path 210 to achieve the diversity and efficient transmission of light beams. Through the precise design of the second light combining sheet 230, the light beam is effectively guided and converges from the second sub-optical path 220 to the second main optical path 210, while ensuring that the light beam of the second main optical path 210 is unobstructed, optimizing the light transmission path.

[0070] As a result, inside the limited space endoscope, the multi-layer second light combining sheet 230 design can maximize the use of available space, integrate multiple light paths, do not increase the light source, and optimize the light source density. In addition, it ensures the directional transmission of the light beam, reduces scattering, enhances the isolation between light paths, improves the imaging clarity and contrast, and is suitable for diagnostic or therapeutic operations. In addition, the second sub-light path 220 can carry light of different wavelengths, and the design of the second light combining sheet 230 enables the multi-wavelength light beams to be effectively merged, broadens the scope of application, and adapts to more medical spectral treatment needs. Obviously, the second light combining sheet 230 can be arranged in three-dimensional space, and when the number of point light sources 100 is equal, the outer diameter of the endoscope using the solution of the present application is smaller.

[0071] For example, in the present embodiment, the number of the second light-combining sheets 230 is 1; of course, in other embodiments, the number of the second light-combining sheets 230 is 2, 3, 4, 5, 6, and so on.

[0072] like Figure 1 As shown, in some embodiments, the first light combining plate 310 has a first transmission band and a first reflection band, the first light combining plate 310 can reflect the light beam with a wavelength located in the first reflection band, and the first light combining plate 310 can transmit the light beam with a wavelength located in the first transmission band; wherein, the wavelength of the light beam propagating along the first main optical path 320 is located in the first transmission band, and the wavelength of the light beam propagating along the first sub-optical path 330 is located in the first reflection band.

[0073] The first light combining plate 310 is divided into two functional areas, namely the first transmission band and the first reflection band, each of which performs a specific optical function. The first light combining plate 310 is in the first reflection band, and can reflect light beams of a specific wavelength, while in the first transmission band, the light beam allows a specific wavelength to penetrate, thereby achieving precise control of the light beam. The wavelength of the light beam propagating along the first main light path 320 is in the first transmission band, which means that the light beam along the first main light path 320 is directly transmitted on the first light combining plate 310 without reflection, thereby keeping the light path unobstructed. The wavelength of the light beam propagating along the first sub-light path 330 is in the first reflection band, which means that the light beam is reflected on the first light combining plate 310 to guide the first main light path 320, thereby achieving the merging of light beams.

[0074] This design optimizes the processing of the light beam on the first light combining sheet 310, and realizes precise control of light beams of different wavelengths through band division, thereby improving the efficiency of light energy. In addition, through the ingenious use of the light beam, the limited space is effectively utilized, which is particularly important for endoscope systems, and improves integration and beam management efficiency.

[0075] The first light combiner 310 is designed to match the wavelength of a specific light beam to ensure that the spectrum requirements are met, whether it is the first main light path 320 or the first sub-light path 330, to meet specific diagnosis or imaging requirements. This design demonstrates the application of complex and efficient optical components in the endoscope light source system, which improves the imaging quality and system performance by precisely controlling the light beam, meeting the precise diagnosis and treatment requirements of modern medical equipment.

[0076] Exemplarily, the wavelength of light received by each first sub-optical path 330 is different, so as to ensure that the first light combining plate 310 is configured to reflect the light beam to the first main light path 320, and the wavelength of the light beam reflected to the first main light path 320 can be transmitted through the remaining first light combining plates 310.

[0077] Optionally, the first sub-optical path 330 is used to receive a monochromatic light beam. For example, one of the first light combining panels 310 is used to receive red light. The first light combining panel 310 that receives the red light is configured to reflect the red light, and the other first light combining panels 310 are configured to transmit the red light.

[0078] Alternatively, in other embodiments, one of the first light combining sheets 310 is used to receive composite light (used to receive composite light formed after the second light combining assembly 200 combines light), and the first light combining sheet 310 receiving the composite light is configured to reflect the composite light, and the other first light combining sheets 310 are configured to transmit the composite light. It is easy to understand that all monochromatic lights in the composite light can be emitted by the first light combining sheet 310 receiving the composite light, and all monochromatic lights in the composite light can be transmitted by the other first light combining sheets 310.

[0079] For example, the composite light is composed of red light and green light, and the first light combining sheet 310 receiving the composite light can reflect red light and green light, and the other first light combining sheets 310 can transmit red light and green light. Of course, in other embodiments, the composite light can also be configured to be formed by combining ultraviolet light and blue light, or by combining blue light and green light; or by combining green light and orange light; or by combining orange light and red light; or by combining blue light, green light, and orange light, etc., which is not specifically limited here.

[0080] like Figure 1 As shown, in some embodiments, the second light combining plate 230 has a second transmission band and a second reflection band, the second light combining plate 230 can reflect the light beam with a wavelength in the second reflection band, and the second light combining plate 230 can transmit the light beam with a wavelength in the second transmission band; wherein, the wavelength of the light beam propagating along the second main optical path 210 is in the second transmission band, and the wavelength of the light beam propagating along the second sub-optical path 220 is in the second reflection band.

[0081] The second light combining sheet 230 is also divided into a second transmission band and a second reflection band, each of which has the functions of transmission and reflection. The light beam of a specific wavelength in the second transmission band is reflected, while the second transmission band allows the light beam of a specific wavelength to be transmitted, thus achieving precise control.

[0082] The wavelength of the light beam propagating along the second main light path 210 is located in the second transmission band, and the light beam propagating along the second main light path 210 directly transmits through the second light combining sheet 230 to ensure that the main light path is unobstructed.

[0083] The wavelength of the light beam propagating along the second sub-optical path 220 is located in the second reflection band, which means that the light beam is reflected on the second light combining plate 230 and guided to the second main light path 210, and the light beams are combined.

[0084] Obviously, the second light-combining plate 230 is designed to optimize beam processing, achieve precise control of beams of different wavelengths through band differentiation, and improve light energy efficiency. In addition, in terms of space utilization, this design also improves beam management, which is particularly suitable for confined space equipment such as endoscopes, improving integration and optical path efficiency. In particular, the second light-combining plate is designed to match specific beam wavelengths, ensure spectral requirements, meet the main optical path and sub-optical path, and meet specific spectral requirements for diagnosis or imaging.

[0085] It should be noted that each first sub-light path 330 is correspondingly provided with a second light combining component 200, so that each first sub-light path 330 can overlap with the second main light path 210 of the corresponding second light combining component 200, so that the composite light after one combination by the second main light path 210 can be transmitted to the first sub-light path 330, so that multiple composite lights or composite light and monochromatic light can be combined for the second time through the first main light path 320.

[0086] Of course, if Figure 1 As shown, since the second light-combining components 200 are distributed in a three-dimensional space, and there is no need to limit the second main light paths 210 of the multiple second light-combining components 200 to be parallel, and there is no need to limit the second sub-light paths 220 to be parallel, as long as the emission and transmission of the light beam can be achieved, there is no technical problem for technicians in this field.

[0087] like Figure 1 As shown, in some embodiments, a plurality of first sub-light paths 330 are arranged at intervals in the circumferential direction of the first main light path 320 ; and a plurality of second sub-light paths 220 are arranged at intervals in the circumferential direction of the second main light path 210 .

[0088] The present application emphasizes the arrangement and integration between the first sub-light path 330 and the first main light path 320, specifically: the first sub-light paths 330 are arranged at intervals in the circumferential direction of the first main light path 320, which means that the first sub-light paths 330 are evenly distributed around or along the first main light path 320, thereby optimizing the introduction and integration of the light beam.

[0089] The second sub-light paths 220 are similarly spaced apart in the circumferential direction of the second main light path 210 and are also arranged evenly, thereby ensuring the orderly introduction of the light beams and improving the efficiency and management of light energy.

[0090] Obviously, this approach can achieve space optimization. This layout effectively utilizes the limited radial space, especially for endoscope systems where space is extremely critical, and maximizes optical path integration and beam integration.

[0091] Furthermore, the circumferential spacing distribution of the first sub-optical path 330 and the second sub-optical path 220 ensures the balanced introduction of the light beam, avoids the concentration or overlap of the light beam aggravating a specific area, optimizes the light beam distribution, and improves the imaging quality.

[0092] In some embodiments, the first main light path 320 and the first sub-light path 330 are arranged vertically, and the second main light path 210 and the second sub-light path 220 are arranged vertically.

[0093] In this embodiment, this design layout describes that the first main light path 320 and the first sub-light path 330 are arranged perpendicular to each other in the endoscope light source system, and the second main light path 210 and the first sub-light path 330 are arranged perpendicular to each other. The specific structural features are as follows:

[0094] The first main optical path 320 and the first sub-optical path 330, the second main optical path 210 and the second sub-optical path 220 are all arranged vertically. Compared with the planar layout, this vertical layout is more three-dimensional in the spatial dimension and optimizes the optical path integration, especially in the space-constrained endoscope system, to improve the optical path integration. Beam control and integration:

[0095] The first main optical path 320 and the second main optical path 210 serve as the main channels of the light beam, and the first sub-optical path 330 and the second sub-optical path 220 vertically guide the light beam. Such a design helps to efficiently convert and integrate the light beam in three-dimensional space and reduce light path conflicts. The vertical integration design requires precise optical design and positioning to ensure accurate light beam guidance, avoid loss, optimize light energy efficiency, and improve system performance.

[0096] Obviously, vertical design may be particularly important in space-constrained devices, such as endoscopes, to optimize optical path configuration, improve light source utilization, and adapt to device miniaturization.

[0097] like Figure 1 As shown, in some embodiments, the endoscope light source system also includes a light guide component 400 and a light source component, the light guide component 400 has an illumination light path 430, and the illumination light path 430 is located in the extension path of the first main light path 320; the light source component has a plurality of point light sources 100, and the plurality of point light sources 100 can respectively emit directional light beams of different wavelengths; wherein the plurality of point light sources 100 are distributed in a three-dimensional space, and the first main light path 320, the first sub-light path 330, the second main light path 210 and the second sub-light path 220 are respectively provided with point light sources 100.

[0098] In this embodiment, the endoscope light source system design demonstrates highly integrated and complex light source management, closely combining the optical path with the light source assembly and the light guide 420 light path, with the following specific features:

[0099] The illumination optical path 430 of the light guide assembly 400 is integrated with the extension path of the first main optical path 320, which means that the light guide assembly 400 is designed to optimize the optical path, which may include optical fiber, optical waveguide or microstructure to ensure the transmission of light beams. The light source assembly has multiple point light sources 100, each of which can emit a specific wavelength light beam to achieve spectrum diversity, distributed in three-dimensional space, and provide customized light sources for different optical paths, thereby improving the flexibility and efficiency of the light source.

[0100] Obviously, the point light source 100 is arranged in three-dimensional space, corresponding to the main light path and the sub-light path, to ensure the precise directivity and efficient introduction of the light beam, reduce loss, and improve the integration of the light source. The point light source 100 with different wavelengths provides different spectral requirements for each light path, optimizes imaging and diagnosis and treatment applications, and meets the requirements of different tissues or spectral responses.

[0101] In other words, by precisely determining the optical path layout of the light guide assembly 400 and the light source, the light beam introduction is optimized, the light source utilization is improved, and the special requirements of complex endoscopes are met. The three-dimensional point light source 100 layout and the spectrum coverage of different wavelengths improve the spectral adaptability, provide rich spectrum options for diagnosis and treatment, and improve clinical applications.

[0102] like Figure 1 As shown, in some embodiments, the light guide assembly 400 includes a light guide 420 and a focusing lens 410, the light guide 420 has a light incident end, and the light guide 420 is extended along the illumination light path 430; the focusing lens 410 is installed at the light incident end.

[0103] Through the combination of light guide 420 and focusing lens 410, the introduction and focusing of light are optimized, and the specific features are as follows: the light guide 420 is designed with the light input end as the light beam entrance, and the light guide 420 extends along a set path, indicating that the light guide component 400 may be an optical fiber, a light guide 420 tube or an optical waveguide structure, ensuring the stable transmission of the light beam in the predetermined path.

[0104] The focusing lens 410 is installed at the light input end. The addition of the focusing lens 410 is to improve the focusing performance of the light, ensure that the light beam can be efficiently converged when entering from the light input end of the light guide 420, reduce scattered distortion, and improve the light energy efficiency. This setting has the following effects: the cooperation between the light guide 420 and the focusing lens 410 realizes the precise light beam control from the light source to the target area, reduces light loss, improves the efficiency of the light guide 420, and optimizes the utilization rate of the light source. The addition of the focusing lens 410, especially at the light input end of the light guide 420, can be regarded as an efficient use of limited space, especially in the endoscope system, where every inch of space is valuable, and improves the integration of the optical path.

[0105] Obviously, through the focusing ability of the condenser lens 410, the light intensity distribution of the light beam in the target area is more uniform, which improves the imaging clarity and is suitable for the strict requirements of high resolution and clear imaging in the endoscope system. This design improves the integration of the light source component. The light guide 420 is combined with the condenser lens 410 to optimize the light path, which is suitable for complex system design, such as endoscopes, and improves light path management.

[0106] Exemplarily, the focusing lens 410 is coaxially mounted at the light incident end.

[0107] like Figure 2 As shown, in some embodiments, the point light source 100 includes a solid light source 110 and a collimating lens 120 , and the collimating lens 120 is installed at the output end of the solid light source 110 .

[0108] In these embodiments, the endoscope light source system further optimizes the output quality and directionality of the light beam by directly integrating the solid light source 110 with the collimating lens 120, and the specific features are as follows:

[0109] The solid light source 110 is integrated with the collimating lens 120, with the solid light source 110 as the core. The solid light source 110, such as LED and laser diode, provides a stable and efficient light source, which is suitable for high-demand light sources such as endoscopes. The collimating lens 120 is installed at the output end. The function of the collimating lens 120 is to correct or focus the light beam output by the solid light source 110, reduce the scattering angle, improve the collimation of the light beam, and ensure the concentration of light energy. Among them, the collimating lens 120 directly acts on the output end of the light source to ensure the high directivity of the light beam, reduce scattering loss, and improve the light energy efficiency, especially in the endoscope system, where the optical path requires precision.

[0110] In addition, the collimating lens 120 is integrated into the solid light source 110, which reduces additional optical path components, saves space, adapts to the compact design of the endoscope system, and optimizes space utilization.

[0111] In summary, the direct integration design of the solid light source 110 and the collimating lens 120 in the endoscope light source system optimizes the quality and directionality of the light beam, saves space, adapts to demanding medical diagnosis and treatment applications, and simplifies system design and maintenance.

[0112] In some embodiments, the light beam emitted by the point light source 100 is monochromatic light, and a plurality of point light sources 100 are respectively used to emit light beams of different wavelengths.

[0113] In this embodiment, the point light source 100 emits a monochromatic light beam, and the multiple point light sources 100 each emit light beams of different wavelengths to achieve spectrum diversity, and the specific features are as follows:

[0114] Each point light source 100 is designed to emit a single wavelength light beam, which means that the light source, such as a monochromatic LED or a single wavelength laser, provides pure wavelength light, which is suitable for specific needs. In addition, the system integrates multiple point light sources 100, each emitting light beams of different wavelengths, constructing a spectral range, such as RGB combination to achieve white light or specific spectrum lighting, to meet diagnosis and treatment needs.

[0115] The multi-wavelength light source design enables the system to cover a wide spectrum and adapt to different diagnostic and treatment needs, such as endoscopic observation, specific tissue response, enhanced blood flow observation, and improved diagnostic accuracy. Monochromatic beams and monochromatic light sources provide precise spectral control for specific applications, such as fluorescence therapy, photodynamic therapy, and photosensitization therapy, to enhance the therapeutic effect. By controlling the spectrum, the system optimizes the beam quality, reduces stray scattering, improves imaging clarity, matches the spectrum to tissues, enhances endoscopic image contrast, and improves diagnostic confidence.

[0116] Obviously, this method realizes the integration of multiple point light sources 100, takes into account the spatial layout, light path management, optimizes the light path design, reduces light path conflicts, and ensures the compactness and efficiency of the system. In summary, through the system design of the point light source 100 emitting monochromatic light beams and multi-wavelength light beams, the endoscope light source system achieves the flexibility and precise control of the spectrum, meets the various needs of medical diagnosis and treatment, improves the light quality and system efficiency, and takes into account the optimization design of integration and light beams.

[0117] To facilitate understanding of the technical solution of the present application, the present application provides a specific implementation method as follows:

[0118] Exemplarily, the plurality of point light sources 100 include an ultraviolet light source, a blue light source, a green light source, an orange light source, and a red light source.

[0119] In the present application, two first light combining sheets 310 and two second light combining sheets 230, five solid light sources 110, and a light guide 420 for receiving a light beam from one of the multiple solid light sources 110, or combining light from at least two of the multiple solid light sources 110 and forming an illumination light for illuminating the object part are provided. In addition, the present application also has a collimating lens 120 corresponding to each of the multiple solid light sources 110, and a focusing lens 410 corresponding to the light guide 420. Of course, in other embodiments, the number of solid light sources 110, the first light combining sheet 310, and the second light combining sheet 230 can also be set to other numbers, which are not specifically limited here. For example, the number of the first light combining sheets 310 is three, four, five, six, and so on, and the number of the second light combining sheets 230 is three, four, five, six, and so on.

[0120] The miniaturization of the endoscope is achieved by three-dimensionally arranging multiple solid light sources 110. Specifically, five solid light sources 110 are used as an example for explanation. Of course, those skilled in the art can understand that the number of solid light sources 110 of the present invention is not limited to five, and may also be four, three, or even more than five solid light sources 110.

[0121] In addition, specifically, the plurality of solid light sources 110 include: a first solid light source 110 (B light source, i.e., a blue light source) having a light-emitting band of about 455 nm, a second solid light source 110 (UV light source, i.e., an ultraviolet light source) having a light-emitting band of about 415 nm, a third solid light source 110 (G light source, i.e., a green light source) having a light-emitting band of about 530 nm, a fourth solid light source 110 (A light source, i.e., an orange light source) having a light-emitting band of about 610 nm, and a fifth solid light source 110 (R light source, i.e., a red light source) having a light-emitting band of about 630 nm. It is worth noting that the light source types referred to by the solid light sources 110 are not limited to the above examples and can be appropriately adjusted according to needs.

[0122] Thus, through the combination and light combination of the solid light sources 110, a variety of light combination modes can be obtained. For example, white light can be obtained by combining the fifth solid light source 110 (R light source), the third solid light source 110 (G light source), and the first solid light source 110 (B light source). In addition, by adding the fourth solid light source 110 (A light source) on the basis of the RGB white light mode and utilizing the spectrum allocation of the four light sources, the color rendering index of the combined light can be significantly improved, thereby obtaining white light that is closer to natural light.

[0123] For another example, by combining the second solid light source 110 (UV light source) and the third solid light source 110 (G light source), special illumination light that highlights the blood vessels in the submucosal layer can be obtained. Also, by combining the third solid light source 110 (G light source), the fourth solid light source 110 (A light source), and the fifth solid light source 110 (B light source), special illumination light that highlights the deep blood vessels can be obtained.

[0124] For another example, by combining the first solid light source 110 (B light source), the second solid light source 110 (UV light source), the third solid light source 110 (G light source), the fourth solid light source 110 (A light source), and the fifth solid light source 110 (R light source), a special illumination light that highlights the mucosal tissue structure can be obtained.

[0125] In addition, since the first solid light source 110, the second solid light source 110, the third solid light source 110, the fourth solid light source 110, and the fifth solid light source 110 are all similar to the point light source 100, in order to make the light emitted by them have directivity, a first collimating lens 120 is provided corresponding to the first solid light source 110, a second collimating lens 120 is provided corresponding to the second solid light source 110, a third collimating lens 120 is provided corresponding to the third solid light source 110, a fourth collimating lens 120 is provided corresponding to the fourth solid light source 110, and a fifth collimating lens 120 is provided corresponding to the fifth solid light source 110. The collimating lenses 120 respectively transform the light emitted by the corresponding solid light sources 110 into a directional light beam (light column). In addition, a focusing lens 410 is also provided near the light guide 420 to converge the light beam to be incident on the light guide 420 to the light guide 420. The collimator lens 120 and the condenser lens 410 are common collimator and condenser lenses, and their detailed description is omitted here.

[0126] That is, as described above, the first solid light source 110 is a B light source, the second solid light source 110 is a UV light source, the third solid light source 110 is a G light source, the fourth solid light source 110 is an A light source, and the fifth solid light source 110 is an R light source. However, the plurality of solid light sources 110 are not limited to the above, and the positions of the B light source, UV light source, G light source, A light source, and R light source can be appropriately set as needed. Furthermore, the plurality of solid light sources 110 can also be more than 5.

[0127] In addition, the arrangement of the multiple solid light sources 110 is preferably such that light beams with similar peak wavelengths belong to the same second light combining component 200 as much as possible. Specifically, when light beams with similar peak wavelengths are combined, the difference in their cut-off wavelengths (including the transmission cut-off wavelength and the reflection cut-off wavelength) is small. When combining the light of light sources with large differences in cut-off wavelengths, the light combining plates corresponding to these light sources, especially the light combining plates located on the downstream side of the optical path, need to be provided with a wider range of reflection bands and transmission bands, which places higher requirements on the cost and process of the light combining plates. According to the spatial arrangement of the solid light sources 110 of the utility model, each of the multiple light combining plates can be manufactured with the requirement of a cut-off band as low as possible (as narrow as possible).

[0128] In some embodiments, the embodiments of the present application further provide an endoscope, the endoscope comprising any one of the endoscope light source systems of the above embodiments.

[0129] Since the above-mentioned endoscope light source system has the above-mentioned technical effects, the endoscope including the endoscope light source system should have the same technical effects, which will not be repeated here.

[0130] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0131] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0132] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
