[0003] For the absorption of high-power lasers, the internal high-reflective gold-plated cone structure currently used has very high requirements for the use environment. Especially during long-term testing, it is easily affected by pollutants, resulting in reduced laser absorption effect and possible permanent damage. Utility Model Content

[0004] In view of the above problems, an object of an embodiment of the present application is to provide a light source absorption device for achieving long-term and stable absorption of high-power lasers.

[0005] In a first aspect, an embodiment of the present application provides a light source absorbing device, which includes: a hollow light shading body and a light absorbing body; the hollow light shading body extends from the proximal end of the light source absorbing device to the distal end of the light source absorbing device; the light absorbing body is arranged at the distal end of the light source absorbing device, and is configured to absorb light emitted by the light source that passes through the hollow interior of the hollow light shading body; wherein the proximal end of the light source absorbing device is a side of the light source absorbing device close to the light source, and the distal end of the light source absorbing device is a side of the light source absorbing device away from the light source.

The geometric structure of the hollow light shielding body ensures that the light propagates along a predetermined path and eventually reaches the light absorbing body for absorption. The light absorbing body effectively converts light energy into heat energy or other forms of energy, reducing the reflection and scattering of light. Even if a small amount of unabsorbed light is reflected back to the hollow light shielding body, it can be further absorbed by the light shielding body, further reducing environmental interference and energy loss. Not only is the performance and efficiency of the light source absorption device improved, but the stability and safety of the device are also enhanced, making it suitable for longer-term use environments.

[0008] Optionally, in an embodiment of the present application, the light absorber includes a light absorbing surface having a V-shaped groove; the light absorbing surface of the light absorber is arranged in the direction of the light source and is configured to receive light emitted by the light source; the V-shaped groove is configured to reflect light not absorbed by the light absorbing surface of the light absorber to the light absorber.

[0016] In the above implementation process, the embodiment of the present application achieves more efficient light energy management and temperature control by applying a light absorbing coating to the light absorbing surface of the light shield and setting a relative light shield cooling surface. The light absorbing coating effectively absorbs reflected light and improves the light energy absorption efficiency, while the light shield cooling surface reduces the temperature of the light absorbing surface through a cooling system to ensure its long-term stability in a high-power, high-heat environment.

[0017] Optionally, in an embodiment of the present application, the light-shielding body cooling surface includes a light-shielding cooling circuit; the light-shielding cooling circuit is disposed around the light-shielding body cooling surface and is configured to perform heat exchange on the light-shielding body through a cooling liquid.

[0018] In the above implementation process, a shading cooling circuit is arranged on the cooling surface of the shading body of the light source absorption device provided in the embodiment of the present application. When the shading body absorbs or reflects high-energy light, the heat generated can be effectively dissipated by the cooling liquid, thereby preventing the shading body from suffering structural damage or performance degradation due to excessive temperature.

[0019] Optionally, in an embodiment of the present application, the light source absorbing device further includes an aperture; the aperture is disposed at the proximal end of the light source absorbing device and connected to the first end of the light shielding body; the aperture is configured to change the light path of the light source and prevent impurities from entering the light source absorbing device.

[0020] In the above implementation process, by setting an aperture at the proximal end of the light source absorption device, the embodiment of the present application significantly improves the light path control accuracy and internal cleanliness of the device. The aperture can effectively adjust the light path entering the device so that the light is concentrated and orderly transmitted to the light absorber. In addition, the impurity blocking function of the aperture effectively prevents external contaminants from entering the device, reduces the risk of damage to key components of the device, and prolongs the service life and stability of the device.

[0021] Optionally, in an embodiment of the present application, the light source absorbing device includes a shell having a light-shielding body shell, a light-absorbing body shell and a base.

[0022] In the above implementation process, the embodiment of the present application greatly enhances the physical protection, structural strength and thermal management capabilities of the light source absorption device by setting the light shielding body shell, the light absorbing body shell and the shell of the base. The light shielding body shell and the light absorbing body shell effectively protect the internal key components from the influence of the external environment, and at the same time cooperate with the cooling system to improve the thermal management efficiency. The shell of the base provides a stable support platform to ensure the stability of the device during operation.

[0023] The light source absorption device provided in the embodiment of the present application realizes more efficient light absorption and heat dissipation management through the combination of a hollow light shielding body and a light absorbing body.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] 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.

[0036] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0037] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0038] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The light source absorption device is mainly used to manage and process high-energy light sources to ensure equipment safety and operational stability. In the commissioning and testing of high-power lasers, the light source absorption device can effectively absorb excess laser energy to prevent damage to surrounding equipment and the environment; in laser processing and material handling, it can absorb residual or scattered lasers to avoid potential safety hazards; in scientific research experiments and industrial applications, the light source absorption device helps reduce the interference of excess laser on experimental results and protect sensitive equipment; in addition, in safety protection applications involving high-energy lasers, it is an important tool to prevent accidental laser exposure.

[0040] During the research, the applicant found that the current laser absorption devices (e.g., 10,000-watt laser absorption devices) generally adopt a specific structural design, the core of which is a highly reflective gold-plated cone located at the inner center of the device to reflect the incoming high-energy laser beam. In order to deal with these reflected lasers, a water-cooled absorber is arranged around the cone to take away the heat through a water-cooling circulation system and absorb the reflected laser energy.

[0041] However, the current cone structure design has exposed some obvious shortcomings in practical applications. First, due to the extremely high reflectivity of the high-reflectivity gold-plated cone, any slight surface contamination may significantly affect its reflection effect. During the long-term laser light emission test, pollutants such as fine dust and smoke particles in the environment can easily fall onto the surface of the gold-plated cone. Due to the high-energy characteristics of the laser, these pollutants will cause local thermal effects under laser irradiation, resulting in local ablation or damage to the gold-plated layer. Once this happens, the surface reflectivity of the gold-plated cone will drop significantly, affecting the overall performance of the laser absorption device, and this damage is usually permanent and cannot be repaired.

[0042] In addition, the manufacturing process of the highly reflective gold-plated cone is relatively complex and precise, requiring the use of high-purity metal materials and advanced coating technology, and the manufacturing cost is extremely high. Due to its complex geometric structure and high surface quality standards, in actual applications, once the gold-plated cone is damaged, the repair process is very difficult, and even the entire cone needs to be replaced, which not only increases the maintenance cost, but may also cause the equipment to shut down for a long time, further affecting its economy and practicality.

[0043] Based on this, the embodiment of the present application provides a light source absorption device, which performs well in absorbing high-power lasers. Through the arrangement of the light shielding body and the light absorbing body, pollutants can be resisted as much as possible, thereby improving the absorption effect of the laser.

[0044] Please see Figure 1 , Figure 1 This is a first schematic diagram of the structure of the light source absorbing device provided in the embodiment of the present application; the light source absorbing device 100 provided in the embodiment of the present application includes: a hollow light shielding body 110 and a light absorbing body 120.

[0045] The hollow light shielding body 110 extends from the proximal end A of the light absorbing device 100 to the distal end B of the light absorbing device 100 .

[0046] The hollow light shielding body 110 is hollow inside, allowing light to pass through. The hollow light shielding body 110 in the embodiment of the present application is a structure with a certain opening or channel, which is used for light to pass through the hollow part from the near end A of the light source and finally reach the far end B. Due to the provision of the hollow light shielding body 110, the light will not be scattered to other areas except the light source absorption device 100 before reaching the light absorbing body 120.

[0047] In some embodiments, the hollow light shield 110 is a structure extending from the proximal end A to the distal end B, and has a hollow internal channel to ensure that light can propagate along a predetermined path. The hollow light shield 110 may be in a tubular, cone, or other suitable geometric shape to guide the light to concentrate toward the distal end B.

[0048] When light passes through the hollow light-shielding body 110 and reaches the light-absorbing body 120 , the light-absorbing body 120 absorbs the light. In some embodiments, a small amount of unabsorbed light is reflected to the hollow light-shielding body 110 and absorbed by the hollow light-shielding body 110 .

[0049] The light absorber 120 is disposed at the distal end B of the light source absorption device 100 and is configured to absorb the light emitted by the light source passing through the hollow interior of the hollow light shielding body 110. It can be understood that the function of the light absorber 120 is to absorb the arriving light energy and convert it into other forms of energy (such as heat energy), thereby preventing the light from continuing to propagate or reflect into the surrounding environment. The light absorber 120 is usually made of a high-efficiency absorption material and can absorb the incoming light energy to the greatest extent to reduce reflection or scattering.

[0050] In some embodiments, the light absorber 120 is connected to the second end b of the hollow light shielding body to form a closed structure; in some embodiments, the light absorber 120 is disposed inside the second end b of the hollow light shielding body.

[0051] like Figure 1 As shown, the proximal end A of the light source absorbing device 100 is the side of the light source absorbing device 100 close to the light source, and the distal end B of the light source absorbing device 100 is the side of the light source absorbing device 100 away from the light source.

[0052] In an optional embodiment, the light shield is a hollow cylinder and the light absorber 120 is a cylinder. The light shield and the light absorber 120 are designed as a hollow cylinder and a cylinder respectively, which helps to optimize the light transmission path, enhance the light energy absorption effect, and simplify the structure.

[0053] pass Figure 1 It can be seen that through the light source absorption device 100 in the embodiment of the present application, the light is effectively guided when passing through the hollow light shielding body 110, avoiding the light from scattering to other areas before reaching the light absorbing body 120, thereby improving the concentration and absorption efficiency of light energy. The geometric structure of the hollow light shielding body 110 ensures that the light propagates along a predetermined path and eventually reaches the light absorbing body 120 for absorption. The light absorbing body 120 effectively converts light energy into heat energy or other forms of energy, reducing the reflection and scattering of light. Even if a small amount of unabsorbed light is reflected back to the hollow light shielding body 110, it can be further absorbed by the light shielding body, further reducing environmental interference and energy loss. Not only is the performance and efficiency of the light source absorption device 100 improved, but the stability and safety of the device are also enhanced, making it suitable for a longer period of use.

[0054] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of the light absorber 120 provided in the embodiment of the present application; Figure 2 See on the basis of Figure 3 , Figure 3 Provided for the embodiments of this application Figure 2 An enlarged view of the H region in the middle; in the embodiment of the present application, the light absorber 120 includes a light absorber surface 121 having a V-shaped groove 1211.

[0055] The light absorbing surface 121 of the light absorber is arranged toward the light source and is configured to receive light emitted by the light source. That is, the light absorbing surface directly faces and receives light emitted from the light source, and the light absorbing surface undertakes the main light absorption task and tries to convert the incoming light energy into other forms of energy, such as heat energy.

[0056] The V-shaped groove 1211 is configured to reflect light that is not absorbed by the light absorbing surface 121 of the light absorber to the light absorber 120 .

[0057] When light hits the light absorbing surface, part of the light energy may not be directly absorbed but reflected. The geometric structure of the V-groove 1211 can reflect the unabsorbed light back to the surface of the light absorbing body 120 or reflect it to the light shielding body, so that it is absorbed by the light absorbing body 120 itself or the light shielding body.

[0058] In some embodiments, the V-grooves 1211 are evenly distributed on the light absorbing surface, and each V-groove 1211 presents a “V”-shaped groove.

[0059] In an optional embodiment, the V-shaped groove 1211 includes a plurality of concentric V-shaped grooves 1211 with different radii. The design of a plurality of concentric V-shaped grooves 1211 with different radii can effectively increase the number of reflections of light, and improve the absorption rate and utilization efficiency of light energy.

[0060] It should be noted that the angle of the V-shaped portion of the V-shaped groove in the embodiment of the present application can be designed according to actual conditions. For example, the angle of the V-shaped groove can be any angle between 30° and 150°, and preferably, the angle of the V-shaped groove is 90°.

[0061] It should be noted that the V-shaped tip of the V-shaped groove in the embodiment of the present application is not an absolute V-shaped tip. In practical applications, for the convenience of processing, it can also be a slightly rounded fillet transition. It is also possible. Those skilled in the art can understand that it does not refer to an absolute V in physics.

[0062] pass Figure 2 and Figure 3 It can be seen that by setting the V-groove 1211 on the light absorbing surface 121 of the light absorbing body, the embodiment of the present application significantly improves the light absorption efficiency. The V-groove 1211 structure can capture and guide the light that is not directly absorbed, and through multiple reflections, the light has a greater probability of being absorbed by the light absorbing surface; even if it is not absorbed by the light absorbing surface 121 of the light absorbing body, it can be reflected to the light shielding body and absorbed by the light shielding body. Therefore, the light source absorption device 100 provided in the embodiment of the present application reduces the scattering of light energy and improves the overall light energy conversion efficiency.

[0063] Please see Figure 4 , Figure 4A cross-sectional view of a light source absorption device 100 provided in an embodiment of the present application; in an optional implementation of the embodiment of the present application, the light absorber 120 further includes a temperature control surface relative to the light absorber absorption surface 121; the temperature control surface includes a light absorber cooling circuit 1221.

[0064] like Figure 4 As shown, the light absorber cooling circuit 1221 is disposed around the temperature control surface and is configured to perform heat exchange on the light absorber 120 through a cooling liquid.

[0065] Since the light absorber 120 generates a large amount of heat when absorbing high-energy light, the temperature control surface dissipates the heat in a timely manner through the cooling circuit to maintain a stable temperature of the light absorber 120 and prevent performance degradation or structural damage due to overheating.

[0066] In more detail, the cooling circuit is designed to be wound along the temperature control surface, and can be presented as a coiled pipe or other suitable flow channel structure, in which the coolant circulates. When the coolant passes through the light absorber cooling circuit 1221, it exchanges heat with the light absorber 120, takes away the heat accumulated on the surface of the light absorber 120, and effectively controls the temperature of the light absorber 120. It should be noted that the coolant is generally an efficient cooling medium, such as water or other liquids with good thermal conductivity.

[0067] In simple terms, the temperature control surface is located on the back of the light absorber 120, and the cooling loop is coiled along the temperature control surface, close to the surface of the light absorber 120, forming an effective heat exchange path. The cooling loop may be embedded or surface-attached to ensure that the coolant can cover the temperature control surface to the maximum extent and enhance the heat exchange effect. The coolant enters the cooling loop through a pump cycle, takes away the heat from the temperature control surface and flows out, and may be connected to an external cooling device (such as a radiator or cooling tower), thereby forming a closed cooling system.

[0068] pass Figure 4 It can be seen that by setting a light absorber cooling circuit 1221 on the temperature control surface of the light absorber 120, the embodiment of the present application improves the thermal management capability of the light source absorption device 100. The heat generated by the light absorber 120 when absorbing high-energy light can be dissipated in time through the coolant to avoid the light absorber 120 from being too hot, ensuring its continuous and efficient operation. This not only effectively extends the service life of the light absorber 120, and improves the stability and reliability of the light source absorption device 100, but also makes the temperature control process more controllable, can meet the needs of various high-power light source applications, and provides a guarantee for the long-term stable operation of the light source absorption device 100.

[0069] Please continue to see Figure 2 In an optional implementation of the embodiment of the present application, the temperature control surface of the light source absorption device 100 further includes a temperature sensor 1222;

[0070] The temperature sensor 1222 is configured to sense the temperature of the light absorber 120 .

[0071] The temperature control surface not only includes a cooling circuit, but also has a temperature sensor 1222 installed thereon. The temperature sensor 1222 may be embedded or surface-attached, and directly contacts the light absorber 120 to accurately sense the temperature of the light absorber 120. The temperature sensor may be an infrared temperature sensor.

[0072] In some embodiments, for example Figure 2 As shown, the temperature sensor 1222 is disposed between the water inlet and the water outlet of the light absorber cooling loop 1221 .

[0073] It can be seen that the light source absorption device 100 provided in the embodiment of the present application improves the temperature control accuracy and response speed by adding the temperature sensor 1222 on the temperature control surface, which can ensure that the light absorber 120 works within the optimal temperature range, prevent performance degradation or damage caused by temperature fluctuations, and extend the service life of the device.

[0074] Please see Figure 5 , Figure 5 Schematic diagram of a light-shielding body provided for an embodiment of the present application; in the embodiment of the present application, the hollow light-shielding body 110 includes a light-shielding body light-absorbing surface 112 and a light-shielding body cooling surface 111; the light-shielding body light-absorbing surface 112 and the light-shielding body cooling surface 111 are arranged relative to each other; the light-shielding body light-absorbing surface 112 includes a light-absorbing coating; wherein the light-absorbing coating is configured to absorb light reflected by the light-absorbing body 120; the light-shielding body cooling surface 111 is configured to reduce the temperature of the light-shielding body light-absorbing surface 112.

[0075] Among them, the light-absorbing coating is usually composed of one or more layers of materials that have high absorptivity and can absorb light energy in a variety of wavelength ranges. Common materials include metals, metal ceramics, carbon nanotube mixtures, etc. The preparation techniques of light-absorbing coatings are diverse, including chemical coating, plasma spraying, magnetron sputtering, etc.

[0076] In some embodiments, the light-absorbing coating can be an ultra-black light-absorbing film. The ultra-black light-absorbing film is a surface material product with a special structure. Unlike traditional black materials (carbon black, graphite, etc.), it can absorb almost all light (ultraviolet light, visible light, near-infrared light, and far-infrared light, etc.) incident on the surface of the material without reflection.

[0077] The light-absorbing surface 112 of the light-shielding body is the side of the hollow light-shielding body 110 that is in direct contact with the light, and is covered with a light-absorbing coating. The light-absorbing coating is used to absorb the light reflected back from the light-absorbing body 120, reduce the impact of the reflected light on other components in the device, and thus improve the light energy absorption efficiency of the entire device.

[0078] The light shielding body cooling surface 111 is located on the side opposite to the light absorbing surface, and is designed to reduce the temperature of the light shielding body light absorbing surface 112 by connecting to the cooling system. The light shielding body cooling surface 111 realizes heat exchange with the light shielding body light absorbing surface 112 through the circulation of the coolant, effectively dissipates heat, prevents the light absorbing surface from overheating due to long-term exposure to high-energy light, and ensures stable operation of the device.

[0079] pass Figure 5 It can be seen that the embodiment of the present application achieves more efficient light energy management and temperature control by applying a light absorbing coating to the light absorbing surface 112 of the light shielding body and providing a corresponding light shielding body cooling surface 111. The light absorbing coating effectively absorbs reflected light and improves the light energy absorption efficiency, while the light shielding body cooling surface 111 reduces the temperature of the light absorbing surface through a cooling system to ensure its long-term stability in a high-power, high-heat environment.

[0080] Please continue to see Figure 4 In an optional implementation of the embodiment of the present application, the light-shielding body cooling surface 111 includes a light-shielding cooling circuit 1111.

[0081] The light-shielding cooling circuit 1111 is disposed around the light-shielding body cooling surface 111 and is configured to perform heat exchange on the light-shielding body through a cooling liquid.

[0082] The cooling circuit is arranged on the cooling surface 111 of the light shield through a pipe or a flow channel to form a complete circulation path. The coolant flows in the circuit, exchanges heat with the light shield, and finally takes away excess heat. The temperature and flow rate of the coolant can be adjusted according to the temperature change of the light shield.

[0083] It can be seen from this that a shading cooling circuit 1111 is provided on the cooling surface of the shading body of the light source absorption device 100 provided in the embodiment of the present application. When the shading body absorbs or reflects high-energy light, the heat generated can be effectively dissipated through the cooling liquid, thereby preventing the shading body from suffering structural damage or performance degradation due to excessive temperature.

[0084] Please continue to see Figure 5 In an optional implementation manner of the embodiment of the present application, the light source absorbing device 100 also includes an aperture 130 .

[0085] The aperture 130 is disposed at the proximal end A of the light absorbing device 100 and connected to the first end a of the light shielding body. The aperture 130 is configured to change the light path of the light source and prevent foreign matter from entering the light absorbing device 100 .

[0086] The aperture 130 is a component with a specific opening, and its shape and size may be adjustable to adapt to different light sources and application requirements. The aperture 130 is directly connected to the first end a of the light shielding body and fixed to the proximal end A of the light source absorbing device 100. The opening of the aperture 130 controls the light entering the device so that it passes through the hollow light shielding body 110 at a specific angle and path. In some embodiments, the aperture 130 may be designed to be deformable or replaceable to adapt to different light characteristics and experimental requirements.

[0087] In some embodiments, the structure of the aperture 130 also includes a fine grid or filter, which can effectively block impurities such as dust and particles in the air and prevent them from entering the interior of the device, especially preventing them from falling on the light absorber 120 or other components.

[0088] It can be seen that by setting the aperture 130 at the proximal end A of the light source absorption device 100, the embodiment of the present application significantly improves the light path control accuracy and internal cleanliness of the device. The aperture 130 can effectively adjust the light path entering the device so that the light is concentrated and orderly transmitted to the light absorber 120. In addition, the impurity blocking function of the aperture 130 effectively prevents external contaminants from entering the interior of the device, reduces the risk of damage to key components of the device, and prolongs the service life and stability of the device.

The light shielding body shell 141 and the light absorbing body shell 142 effectively protect the internal key components and prevent the influence of the external environment, while cooperating with the cooling system to improve the thermal management efficiency. The shell 140 of the base 143 provides a stable support platform to ensure the stability of the device during operation.

[0092] In summary, the light source absorption device 100 provided in the embodiment of the present application significantly improves the absorption efficiency of the high-power laser light source and the overall stability of the device. The device includes a hollow light shielding body 110, a light absorbing body 120, an aperture 130, and a temperature control system equipped with a cooling circuit and a temperature sensor 1222. The hollow light shielding body 110 guides the light to be transmitted along a predetermined path, and the aperture 130 adjusts the light path and blocks impurities from entering, ensuring that the light reaches the light absorbing body 120 accurately. The V-groove 1211 design of the light absorbing body 120 causes the light that is not directly absorbed to be reflected multiple times, further improving the light absorption efficiency.
