[0033] This utility model proposes a light source component 1.

[0034] Combination Figures 1 to 4 As shown, in one embodiment of the present invention, the light source assembly 1 includes a mounting bracket 10, a xenon lamp 20, and a light-transmitting plate 30; a reflective groove 11 is provided on one side of the mounting bracket 10; the xenon lamp 20 is disposed in the reflective groove 11; the light-transmitting plate 30 is disposed on one side of the mounting bracket 10 and seals the reflective groove 11, and the light-transmitting plate 30 and the groove wall of the reflective groove 11 form a cooling cavity, and coolant is injected into the cooling cavity;

[0035] The light emitted by the xenon lamp 20 passes through the light-transmitting plate 30 after being reflected from the opening of the reflector groove 11 or through the groove wall of the reflector groove 11.

[0036] In the embodiment, the mounting bracket 10 is used to mount the xenon lamp 20, and the material of the mounting bracket 10 is selected from aluminum, copper and other materials with high thermal conductivity, so as to improve the heat dissipation efficiency of the xenon lamp 20. The xenon lamp 20 is arranged in the light reflection groove 11, so that the light emitted by the xenon lamp 20 can be directly emitted through the slot of the light reflection groove 11 or reflected through the slot wall of the light reflection groove 11 and then emitted through the slot of the light reflection groove 11. Therefore, the design of the light reflection groove 11 can guide and converge the treatment light emitted by the xenon lamp 20, thereby improving the treatment effect. The size and shape of the light reflection groove 11 can be adjusted according to the size and shape of the xenon lamp 20, for example, the cross section can be rectangular, U-shaped or elliptical. The size and shape of the slot of the light reflection groove 11 will affect the treatment range of the phototherapy instrument. In actual application, the treatment of different shapes and sizes of treatment areas can be realized by changing the size and shape of the slot of the light reflection groove 11. Further, the xenon lamp 20 is arranged at the center position of the light reflection groove 11 or on the vertical plane of the slot of the light reflection groove 11, so that the light emitted from the slot of the light reflection groove 11 is more uniform, thereby improving the consistency of the phototherapy effect in the treatment area. In addition, in order to improve the reflection effect of the light reflection groove 11 on the light of the xenon lamp 20 and reduce the attenuation degree of the light of the xenon lamp 20 after being reflected by the slot wall of the light reflection groove 11, a polishing process can be used to improve the smoothness of the slot wall of the light reflection groove 11, or a reflective film can be plated on the slot wall of the light reflection groove 11.

[0037] The xenon lamp 20 is fixed at both ends of the mounting bracket 10 through the connecting structure. Specifically, the connecting structure can be a threaded connection structure, a plug-in structure or an interference fit connection structure, etc. The connecting structure not only provides physical support for the xenon lamp 20, but also has the function of installing and fixing the power transmission line, so as to facilitate the electrical connection between the xenon lamp 20 and the external power supply circuit.

[0038] The light transmission plate 30 is sealed and mounted at the slot of the light reflection groove 11, and is surrounded by the slot wall of the light reflection groove 11 to form a cooling cavity. The cooling cavity is filled with a cooling medium, such as water, which has good heat conduction performance and good light transmission effect, so as to absorb the heat generated by the xenon lamp 20 during operation, prevent overheating from damaging the xenon lamp 20, and as far as possible reduce the energy loss between the xenon lamp 20 and the light transmission plate 30, and improve the penetration efficiency of the light of the xenon lamp 20. The material of the light transmission plate 30 should be selected from materials with good light transmission and heat resistance, such as optical grade polycarbonate, glass, acrylic and the like, which have good light transmission effect and certain structural strength, so as to improve the light output effect and structural reliability of the light source assembly 1.

[0039] In the prior design, when the light emitted by the xenon lamp 20 transmits through the glass tube and is emitted towards the groove wall of the light-reflecting groove 11, part of the light will transmit through the glass tube again after being reflected by the light-reflecting groove 11 and then be emitted from the light outlet of the light-reflecting groove 11. Since part of the light transmits through the glass tube at least twice, the energy loss is large and the energy utilization efficiency is low. However, in the design of the present application, the light-reflecting plate 30 is arranged at the groove opening of the light-reflecting groove 11, so that the light emitted by the xenon lamp 20 towards the groove wall of the light-reflecting groove 11 is directly transmitted through the light-reflecting plate 30 after being reflected by the light-reflecting groove 11, and the light transmits through the light-reflecting plate 30 only once. This design reduces the energy loss caused by multiple transmissions and improves the energy utilization efficiency of the xenon lamp 20, so that more light energy can effectively act on the target area and the treatment effect is enhanced.

[0040] In combination Figure 4 As shown in the embodiment of the present application, the light-reflecting groove 11 has an arc-shaped bottom surface.

[0041] In the embodiment, the light-reflecting groove 11 has an arc-shaped bottom surface, for example, the light-reflecting groove 11 can be designed to have a U-shaped cross-sectional shape or a semicircular shape. This design aims to optimize the light reflection path and improve the light concentration and energy utilization efficiency. By adopting an arc-shaped bottom surface, the light-reflecting groove 11 can more effectively focus the light emitted by the xenon lamp 20 towards the direction of the groove opening, thereby enhancing the light intensity of the light source assembly 1 on the target treatment area.

[0042] Further, the arc surface of the light-reflecting groove 11 can be designed as a continuous smooth curved surface, for example, a semicircular surface or a parabolic surface, or an approximate curved surface structure composed of multiple continuous small arc surfaces. This design can further facilitate the improvement of the light reflection characteristics and the targeted enhancement of the light intensity at specific positions in the treatment area, thereby adapting to different treatment requirements.

[0043] Since the bottom of the light-reflecting groove 11 is arc-shaped, the xenon lamp 20 can be placed near the top of the arc in the embodiment, so that the emitted light is more easily converged along the arc. There should be sufficient gap between the outer periphery of the xenon lamp 20 and the groove wall of the light-reflecting groove 11 to facilitate the smooth flow of the cooling medium and carry away the heat generated during operation. This can protect the xenon lamp 20 from high temperature damage and help maintain stable light output.

[0044] In combination Figure 4 As shown in the embodiment of the present application, the mounting bracket 10 has two light-reflecting grooves 11 on one side, and the light source assembly 1 includes two xenon lamps 20, each xenon lamp 20 being arranged in a light-reflecting groove 11, and the light-reflecting plate 30 being sealed at the groove openings of the two light-reflecting grooves 11.

[0045] In the embodiment, two xenon lamps 20 are arranged in the corresponding light reflection grooves 11 respectively, and the length and shape of the xenon lamps 20 are matched with the light reflection grooves 11. The light emitted by each xenon lamp 20 is reflected by the light reflection groove 11 and then emitted from the slot of the corresponding light reflection groove 11. By arranging two light reflection grooves 11 and two xenon lamps 20, the treatment range of the light source assembly 1 in a single treatment is improved. Further, the two light reflection grooves 11 arranged on the mounting bracket 10 are parallel to each other or the relative positions are adjusted according to requirements to adapt to different light distribution requirements.

[0046] It can be understood that, in order to improve the uniformity of the light intensity in the treatment area, the two light reflection grooves 11 can be arranged adjacent to each other, and the light transmission plate 30 can also seal the slots of the two light reflection grooves 11 at the same time, thereby reducing the structural cost. In other embodiments, a plurality of light reflection grooves 11 and a plurality of xenon lamps 20 can be arranged, and each xenon lamp 20 is arranged in a light reflection groove 11. Further, the light source assembly 1 further comprises a connecting head, which is arranged at one end of the xenon lamp 20 and is welded in series to realize electrical connection.

[0047] In combination with Figures 2 to 4 As shown in the utility model, in an embodiment of the utility model, the extension directions of the two light reflection grooves 11 are perpendicular to the xenon lamps 20, the two light reflection grooves 11 are arranged adjacent to each other, the groove wall between the two light reflection grooves 11 is lower than the groove wall on the other side of the two light reflection grooves 11, the two light reflection grooves 11 are connected and form a cooling cavity together with the light transmission plate 30.

[0048] In the embodiment, the two light reflection grooves 11 are arranged adjacent to each other, and the groove wall between the two light reflection grooves 11 is lower than the groove wall on the two sides, forming a low connecting area, that is, the groove wall of the two light reflection grooves 11 and the light transmission plate 30 form a cooling cavity with an M-shaped cross section. This design makes the two light reflection grooves 11 connected, so that the cooling liquid can cool the xenon lamps 20 in the two light reflection grooves 11 at the same time, and therefore only one cooling liquid circuit needs to be arranged on the mounting bracket 10, thereby simplifying the structure design and reducing the structural processing cost.

[0049] In addition, the design of the lower groove wall between the other two light reflection grooves 11 not only facilitates the circulation and heat exchange of the cooling liquid between the two light reflection grooves 11, but also reduces the obstruction to the light path, thereby improving the light uniformity and light coverage effect of the treatment area corresponding to the two light reflection grooves 11.

[0050] In combination with Figure 4 As shown in the utility model, in an embodiment of the utility model, the mounting bracket 10 is recessed to form a mounting groove 12 at the outer periphery of the two light reflection grooves 11, a sealing groove 13 is arranged on the groove bottom of the mounting groove 12, the light source assembly 1 further comprises a sealing part, the sealing part is embedded in the sealing groove 13, and the light transmission plate 30 is embedded in the mounting groove 12 and sealingly cooperates with the sealing part.

[0051] In the embodiment, the mounting groove 12 on the mounting bracket 10 is located at the outer periphery of the two light reflection grooves 11, so that the opening of the two light reflection grooves 11 is lower than the surface of the mounting bracket 10. The shape of the mounting groove 12 is matched with the light transmission plate 30, so as to improve the sealing effect of the light transmission plate 30 on the light reflection groove 11. The depth and width of the mounting groove 12 can also be set according to the light transmission plate 30, for example, the depth and width of the mounting groove 12 can be set to be matched with the light transmission plate 30, and when the light transmission plate 30 is mounted in the mounting groove 12, the light transmission plate 30 abuts or is adjacent to the groove wall of the mounting groove 12, and the surface of the light transmission plate 30 is flush with the surface of the mounting bracket 10. In this way, the light transmission plate 30 can be stably fixed in the mounting groove 12, the sealing effect on the light reflection groove 11 is improved, and the overall appearance of the light source assembly 1 is improved.

[0052] A sealing groove 13 is arranged around the bottom of the mounting groove 12. The cross section of the sealing groove 13 can be circular, rectangular or other shapes that facilitate the embedding of the sealing part. The sealing groove 13 not only facilitates the installation and positioning of the sealing part, improves the stability of the sealing part, but also enhances the sealing effect and prevents the leakage of the cooling medium.

[0053] The sealing part is made of materials with good elasticity and chemical corrosion resistance, such as silicone rubber or fluororubber. These materials can maintain good sealing performance in a wide temperature range to adapt to the high temperature environment generated by the xenon lamp 20 during operation. The sealing part is embedded in the sealing groove 13 by pressing or bonding, ensuring that it is fixed in the sealing groove 13 and cannot be easily displaced. In addition, the sealing part can also be an adhesive, which is filled in the sealing groove 13. When the light transmission plate 30 is embedded in the mounting groove 12, the light transmission plate 30 is bonded with the adhesive, thereby achieving the fixation of the light transmission plate 30 and the sealing of the light reflection groove 11.

[0054] In an embodiment of the utility model, the groove wall of the light reflection groove 11 is provided with a reflective film.

[0055] In the embodiment, the reflective film is arranged on the groove wall of the light reflection groove 11, which improves the light reflection efficiency, reduces energy loss, and enhances the illumination intensity in the target area.

[0056] The reflective film can be made of various high-reflectivity materials, such as metal plating (e.g. silver or aluminum) or special optical coating. These materials can provide extremely high reflectivity in the visible light band, ensuring that as much light as possible is reflected and directed to the target area. In addition, the reflective film also has good durability and corrosion resistance, and can work stably for a long time in the high temperature and cooling medium environment generated by the xenon lamp 20 during operation.

[0057] In order to ensure that the reflective film can uniformly cover the inner wall of the light reflection groove 11, a vacuum evaporation, sputtering coating or spraying process can be used for processing. These processes not only ensure the uniform thickness of the reflective film, but also effectively fill the small bumps and bumps on the surface of the light reflection groove 11, further improving the reflection effect. For the light reflection groove 11 with a complex shape, a flexible film technology can also be considered to attach the preformed reflective film to the groove wall to ensure that each corner is fully covered.

[0058] In combination with Figure 2 and Figure 4 As shown in the embodiment of the present application, a weight reduction groove 14 is formed on one side of the mounting bracket 10 relative to the light reflection groove 11. Since the light source assembly 1 is applied to a light therapy instrument, when a medical staff holds the light therapy instrument for treatment, the weight of the light therapy instrument will affect the control accuracy and cause hand pain when the weight is heavy. Therefore, the weight reduction groove 14 is formed on the mounting bracket 10 to reduce the overall weight of the light source assembly 1 to improve the above problems. At the same time, by forming the weight reduction groove 14, the material of the mounting bracket 10 can also be reduced, thereby reducing the production cost. The cross-sectional shape of the weight reduction groove 14 can be U-shaped, square or other shapes.

[0059] In combination with Figure 1 and Figure 5 As shown in the embodiment of the present application, the light source assembly 1 further comprises a light guide lens 60, which is arranged on the side of the light transmission plate 30 away from the xenon lamp 20 and is used for focusing the light transmitted by the xenon lamp 20 through the light transmission plate 30.

[0060] In the embodiment, the light guide lens 60 is used to focus the light after being transmitted by the xenon lamp 20 through the light transmission plate 30, so as to achieve more concentrated and efficient lighting effect. The light guide lens 60 is selected from materials with high light transmittance and excellent optical performance, such as optical-grade polycarbonate or glass. These materials not only can efficiently transmit light, but also have good heat resistance and mechanical strength, ensuring long-term stable work in high-temperature environment. According to specific application requirements, the light guide lens 60 can be designed as a convex lens, a concave lens or a flat lens structure to achieve different focusing effects. For example, a convex lens can converge parallel light to a point, while a concave lens can diverge light to adjust the size of the light spot, suitable for the needs of different treatment areas.

[0061] In order to ensure that the light guide lens 60 can accurately receive and process the light transmitted by the light transmission plate 30, the light guide lens 60 is arranged on the side of the light transmission plate 30 away from the xenon lamp 20 or on the side of the mounting bracket 10 with the mounting groove 12 through the fixing structure, so as to ensure that the distance between the light guide lens 60 and the light transmission plate 30 is moderate and the relative position is fixed. The fixing structure can be a threaded connection structure, a buckle structure or an adhesive structure, etc., to ensure that the light guide lens 60 will not displace during use.

[0062] In combination Figure 1 And Figure 2 As shown in the embodiment of the present application, the light source assembly 1 further comprises a front cover 51, a rear cover 52 and two sealing members 40. The reflective groove 11 penetrates through both ends of the mounting bracket 10. The front cover 51 and the rear cover 52 are detachably connected to both ends of the mounting bracket 10 and seal both ends of the xenon lamp 20 through the two sealing members 40.

[0063] In this embodiment, the reflective groove 11 is designed to penetrate through both ends of the mounting bracket 10 to facilitate the installation of the xenon lamp 20. Since the reflective groove 11 is designed in a penetrating manner, the two ends of the mounting bracket 10 need to be sealed to ensure the sealing effect of the cooling cavity.

[0064] The front cover 51 and the rear cover 52 are made of high-strength and heat-resistant materials such as aluminum alloy or engineering plastic to ensure that they can withstand the high temperature and pressure generated by the xenon lamp 20 during operation. They are connected to the mounting bracket 10 through bolts or other quick disassembly and assembly structures, which facilitates the maintenance and replacement of the xenon lamp 20. This detachable design facilitates daily cleaning and maintenance, improving the maintenance convenience of the equipment.

[0065] The two sealing members 40 are respectively embedded in the interiors of the front cover 51 and the rear cover 52 to seal both ends of the xenon lamp 20. The sealing members 40 are made of materials with good elasticity and chemical corrosion resistance, such as silicone rubber or fluororubber, to ensure long-term sealing performance in high-temperature environments. The design of the sealing members 40 not only prevents the leakage of cooling medium, but also prevents external pollutants from entering, protecting the safe operation of the xenon lamp 20 and internal components.

[0066] To further improve the cooling effect of the xenon lamp 20, front and rear heat-conducting blocks are provided at both ends of the mounting bracket 10. The front and rear heat-conducting blocks are both provided with mounting holes and are respectively sleeved on the front cover 51, the rear cover 52 and both ends of the xenon lamp 20, so that the heat generated by the xenon lamp 20 can be diffused through the front and rear heat-conducting blocks, improving the cooling effect of the xenon lamp 20.

The water inlet 15 communicates with an external water supply device, and the water outlet communicates with an external drainage device.

Similarly, the water outlet is located at one side of the mounting bracket 10, and a water outlet connector is arranged at one side of the water outlet. When assembling the phototherapy hand tool or the phototherapy instrument, the water inlet connector is communicated with the water inlet pipe 2, and the water outlet connector is communicated with the water outlet pipe 3. The cooling liquid can be water, ethylene glycol or other liquid or gaseous cooling substances. The cooling liquid enters the cooling cavity through the water inlet 15, cools the xenon lamp 20, and is finally discharged from the water outlet to realize the circulating cooling of the xenon lamp 20 in the cooling cavity by the cooling liquid.

[0072] The phototherapy hand tool is provided with a water inlet pipe 2 and a water outlet pipe 3, both of which are communicated with the cooling cavity inside the light source assembly 1. The water inlet pipe 2 is responsible for introducing cooling medium (such as deionized water or other liquid with good heat conductivity) into the cooling cavity to absorb the heat generated by the xenon lamp 20 during operation; and the water outlet pipe 3 discharges the heated cooling medium to form a closed-loop cooling circulation system, effectively reducing the working temperature of the xenon lamp 20, prolonging its service life and ensuring the safe operation of the equipment.

The two water-cooled clamps 410 are internally provided with flow guide channels 411, and the water inlet pipe 2 is sequentially connected with the flow guide channels 411, the cooling cavity and the water outlet pipe 3.

[0074] In the embodiment, the refrigeration assembly 4 comprises two refrigeration sheets 420 and two water-cooled clamps 410. The two refrigeration sheets 420 are respectively arranged on the opposite sides of the light guide lens 60, and the heat generated by the light guide lens 60 during operation is absorbed by directly contacting the light guide lens 60, and the absorbed heat is conducted to the two water-cooled clamps 410. The two water-cooled clamps 410 are clamped on the outer periphery of the two refrigeration sheets 420 and the light guide lens 60, forming a compact cooling system. The two water-cooled clamps 410 are internally provided with flow guide channels 411 for guiding the flow of cooling medium (such as deionized water or other liquid with good heat conduction performance), ensuring that the refrigeration sheets 420 and the light guide lens 60 are effectively cooled.

[0075] The water inlet pipe 2 is sequentially connected with the flow guide channels 411 in the water-cooled clamps 410, the cooling cavity and the water outlet pipe 3, forming a closed-loop cooling circulation system. Since the temperature near the xenon lamp 20 is high during operation of the light source assembly 1, the temperature at the light guide lens 60 is lower than the temperature in the cooling cavity, so the cooling medium first flows into the flow guide channels 411 in the water-cooled clamps 410, absorbs the heat transferred by the refrigeration sheets 420 and the light guide lens 60, then enters the cooling cavity to continue cooling the xenon lamp 20, and finally is discharged through the water outlet pipe 3. This design ensures efficient cooling of the entire phototherapy hand tool, and the same cooling water can effectively cool and cool the light guide lens 60 and the xenon lamp 20, not only prolonging the service life of each component, but also reducing the number of flow guide channels 411 and simplifying the structural design of the phototherapy hand tool.

[0077] The light source assembly 1 is in communication connection with a host computer. The host computer is a core control unit of the light therapy instrument, and is internally provided with a microprocessor, a power management module, a user interface (such as a touch screen or a key panel), a communication interface and other key components. The microprocessor is responsible for processing various operation instructions and coordinating the operation of various subsystems; the power management module ensures that stable and reliable power supply is provided for the entire system; the user interface is convenient for an operator to set treatment parameters and monitor the state of the equipment; and the communication interface is used for real-time communication with the light source assembly 1, and the host computer controls the xenon lamp 20 to be turned on or turned off and adjusts the power of the xenon lamp 20, thereby adapting to different treatment requirements.
