[0051] An embodiment of the first aspect of the present application provides a light therapy device, which improves the heat dissipation performance of a high-power and miniaturized light therapy device by reasonably designing a heat dissipation structure.
[0052] Please refer to Figures 1 to 3 , an embodiment of the present application provides a light therapy device 100, and the light therapy device 100 includes a housing 10, a first radiator 20, and a light source 30.
[0053] An optical output area 101 is provided on the housing 10, that is, at least a part of the housing 10 is set as the optical output area 101. The housing 10 can provide a space for accommodating and installing other components of the light therapy device 100 and provide a protection function.
[0054] Wherein, the housing 10 is a columnar housing, and the housing 10 extends along the axial direction (i.e., the length direction of the housing 10).
[0055] Optionally, the housing 10 is an aluminum shell with good heat dissipation ability. It can be understood that in other embodiments of the present application, the housing 10 can also be made of other materials with good thermal conductivity such as copper and magnesium alloy, which are not limited herein.
[0056] The first radiator 20 is installed in the housing 10. A reflection cavity 221 is provided at a position corresponding to the optical output area 101 of the first radiator 20, and the inner wall of the reflection cavity 221 is mirror-like.
[0057] In this way, the first radiator 20 can optimize the light distribution through the reflection cavity 221, improve the concentration and uniformity of the light, and further enhance the illumination effect; at the same time, the mirror treatment of the inner wall of the reflection cavity 221 can reduce light loss, effectively reflect the light and direct it in the desired direction, thereby improving the overall light emission efficiency.
[0058] The light source 30 is used to emit light therapy light. The light source 30 is installed on the first radiator 20, and the light source 30 is located on one side of the reflection cavity 221. The light emitted by the light source 30 is emitted from the optical output area 101 through the reflection cavity 221, that is, the first radiator 20 is located on the light output side of the light source 30.
[0059] In this way, the light source 30 is directly mounted on the first radiator 20. The direct contact between the two can reduce the thermal resistance in the heat transfer process, enabling heat to be transferred from the light source 30 to the first radiator 20 more quickly, ensuring efficient heat dissipation performance, and meeting the heat dissipation requirements of the miniaturized phototherapy device 100.
[0060] Among them, the light source 30 adopts a high-power light source with high optical power and large heat generation, which can meet the usage requirements.
[0061] In the above-mentioned phototherapy device 100, the first radiator 20 provides a reflection cavity 221 to optimize the light distribution, improve the concentration and uniformity of light, and thus enhance the lighting effect. At the same time, the mirror treatment on the inner wall of the reflection cavity 221 can reduce light loss, effectively reflect the light and direct it in the expected direction, thereby improving the overall luminous efficiency. In addition, the light source 30 is directly mounted on the first radiator 20. The direct contact between the two can reduce the thermal resistance in the heat transfer process, enabling heat to be transferred from the light source 30 to the first radiator 20 more quickly, ensuring efficient heat dissipation performance, meeting the heat dissipation requirements of the miniaturized phototherapy device 100, and solving the technical problem of poor heat dissipation performance of the phototherapy device in the prior art.
[0062] In the embodiments of the present application, the surface of the first radiator 20 and the surface of the reflection cavity 221 are mirrors; or, the surface of the first radiator 20 and the surface of the reflection cavity 221 are metal coatings.
[0063] Optionally, in one embodiment, the first radiator 20 is an integrally formed stainless steel part with a mature preparation process and low cost. Secondly, the integrally formed design reduces the thermal resistance and improves the heat conduction efficiency, so as to have both good thermal conductivity and high reflectivity.
[0064] Please refer to Figure 3 and Figure 4 , in the embodiments of the present application, the first radiator 20 is provided with a heat conduction plate 222 on one side of the reflection cavity 221, and the heat conduction plate 222 is provided with an opening 223. The light source 30 includes a substrate 31 and LED lamp beads 32 arranged on the substrate. The substrate 31 abuts against the side of the heat conduction plate 222 away from the reflection cavity 221, and the LED lamp beads 32 are cooperatively placed in the opening 223.
[0065] In this way, the substrate 31 is adhesively connected to the heat conduction plate 222 provided with the opening 223, enabling the heat energy generated when the LED lamp beads 32 emit light to be quickly conducted to other positions of the first radiator 20 through the heat conduction plate 222. When the LED lamp beads 32 are cooperatively placed in the opening 223, the light emitted by them can be directly directed to the reflection cavity 221, reducing light loss, and the reflection cavity 221 helps to concentrate the light and emit it from the light output area 101, improving the light intensity.
[0066] Specifically, a plurality of LED lamp beads 32 are arranged at intervals on the substrate 31, and the same number of openings 223 are provided on the heat conducting plate 222 adhesively connected to the substrate 31, and the plurality of LED lamp beads 32 are arranged in one-to-one correspondence with the plurality of openings 223.
[0067] To further reduce light loss, the size of the opening 223 is adapted to the LED lamp bead 32.
[0068] In an embodiment of the present application, please refer to Figure 3 , the heat conducting plate 222 is inclined towards the light emitting area 101; and / or, the cross-sectional area of the reflection cavity 221 gradually increases in the direction towards the light emitting area 101.
[0069] It can be understood that the substrate 31 and the heat conducting plate 222 are arranged in the same way.
[0070] In this way, when the substrate 31 and the heat conducting plate 222 are inclined towards the light emitting area 101, it helps to control the distribution and direction of the light beam, and reduces the multiple reflections inside the reflection cavity 221, thereby reducing light loss and improving light efficiency. Secondly, the inclined setting can save space and is suitable for the case where the internal space of the housing 10 is limited. In addition, the cross-sectional area of the reflection cavity 221 gradually increases in the direction towards the light emitting area 101, the number of reflections of the light inside the reflection cavity 221 is reduced, which helps to reduce the light loss caused by internal reflection and improve the light utilization rate. At the same time, it helps the light to be more evenly directed to the light emitting area 101, and improves the coverage area and uniformity of the light in the light emitting area 101.
[0071] Optionally, in some embodiments, the included angle between the heat conducting plate 222 and the length direction of the housing 10 is 35° - 60°.
[0072] It can be understood that in other embodiments of the present application, the cross-sectional area of the reflection cavity 221 can always remain unchanged, but is not limited thereto.
[0073] Please refer to Figure 1 and Figure 3 , in an embodiment of the present application, a light transmitting plate 11 is installed on the housing 10, and the light transmitting plate 11 forms the light emitting area 101. The light transmitting plate 11 can play a role of physical protection to prevent the light source 30 from being affected by the external environment, such as dust, moisture, etc.
[0074] Specifically, the light transmitting plate 11 is rectangular, that is, the light emitting area 101 is a plane. It can be understood that the light emitting surface of the light therapy device 100 is a plane structure, which helps to control the illumination area and make the light evenly distributed within the illumination area.
[0075] It can be understood that in other embodiments of the present application, the light emitting area 101 can be an arc-shaped light emitting area, and correspondingly, the light transmitting plate 11 is an arc-shaped plate, but is not limited thereto.
[0076] In addition, one end of the reflective portion 22 facing the light emitting area 101 is in contact with the light-transmitting plate 11 , which helps to guide the light directly to the light emitting area 101 , thereby improving the guiding efficiency and utilization rate of the light.
[0077] Please refer to Figure 1 and Figure 3 In an embodiment of the present application, the first radiator 20 includes a heat dissipation section 21 and a reflecting portion 22 provided at one end of the heat dissipation section 21, a reflecting cavity 221 is opened in the reflecting portion 22, the heat dissipation section 21 is arranged along the length direction of the shell 10, the heat dissipation section 21 is spaced from the inner wall of the shell 10 on the side facing the light emitting area 101, and the heat dissipation section 21 is in contact with the inner wall of the shell 10 on the side facing away from the light emitting area 101, so as to conduct the heat of the first radiator 20 to the shell 10.
[0078] In this way, the heat dissipation section 21 is arranged along the length direction of the housing 10, and the space inside the housing 10 can be reasonably utilized to increase the surface area of the heat dissipation section 21. The heat dissipation section 21 is arranged at a distance from the inner wall of the housing 10 on the side facing the light emitting area 101, so that there is space between the heat dissipation section 21 and the housing 10 for placing other electrical components, which is convenient for the electrical connection of the internal electrical components. In addition, the side of the heat dissipation section 21 facing away from the light emitting area 101 is in contact with the inner wall of the housing 10, realizing direct contact heat dissipation, which can reduce the thermal resistance of the heat transfer process, so that the heat can be transferred from the internal components to the surface of the housing 10 more quickly, ensuring efficient heat dissipation performance.
[0079] In this embodiment, please refer to Figure 3 and Figure 4 The heat dissipation section 21 includes a heat dissipation plate 211 arranged along the length direction of the shell 10 and a plurality of first fins 212 arranged on one side of the heat dissipation plate 211. The heat dissipation plate 211 is arranged at intervals from the inner wall of the shell 10. The plurality of first fins 212 are arranged at intervals along the width direction of the heat dissipation plate 211. Each first fin 212 is arranged along the length direction of the heat dissipation plate 211. One end of each first fin 212 away from the heat dissipation plate 211 is in contact with the inner wall of the shell 10. The ends of the heat dissipation plate 211 and the first fins 212 are connected to the reflecting portion 22.
[0080] The design of multiple first fins 212 increases the heat dissipation area of the heat dissipation section 21, which helps to improve the heat conduction efficiency. At the same time, a heat dissipation gap is formed between any two adjacent first fins 212, which helps to promote natural convection of air, further improve the heat dissipation efficiency, and avoid local overheating. In addition, the end of the first fin 212 away from the heat dissipation plate 211 is in contact with the inner wall of the housing 10, which not only improves the heat dissipation speed, but also helps to improve the structural stability of the device.
[0081] Optionally, in some embodiments, the plurality of first fins 212 are at least one of straight, serrated, and corrugated.
[0082] Please refer to Figure 3 and Figure 5 , in the embodiment of the present application, the light therapy device 100 further includes a second radiator 40 disposed on the side of the light source 30 facing away from the first radiator 20, and the second radiator 40 is attached to the backlight side of the light source 30.
[0083] In this way, heat dissipation structures are provided on both sides of the light source 30, further improving the heat dissipation efficiency.
[0084] In addition, the outer periphery of the second radiator 40 is attached to the inner wall of the housing 10 to directly conduct the heat of the second radiator 40 to the housing 10. At the same time, it helps to improve the structural stability of the light therapy device 100.
[0085] In this embodiment, please refer to Figure 3 and Figure 5 , the second radiator 40 includes a connecting seat 41 connected to the housing 10 and a plurality of second fin plates 42 disposed on the side of the connecting seat 41 close to the light source 30. The plurality of second fin plates 42 are spaced apart along the width direction of the connecting seat 41, and the end faces of the second fin plates 42 are in contact with the light source 30.
[0086] Optionally, in some embodiments, the plurality of second fin plates 42 are at least one of straight, serrated, and corrugated.
[0087] It can be understood that the end of the second radiator 40 facing the light source 30 is parallel to the heat conducting plate 222 provided with the opening 223. The light source 30 is clamped between the second radiator 40 and the first radiator 20 and is in contact with both.
[0088] To fix the position of the light source 30 and prevent the change of the position of the light source 30 from affecting the light output effect, in this embodiment, please refer to Figure 3 and Figure 4 , a connecting ear 224 is provided on the reflecting portion 22 of the first radiator 20, and through holes are provided at corresponding positions of the connecting ear 224, the light source 30, and the second radiator 40, and the first radiator 20, the light source 30, and the second radiator 40 are detachably connected by screws.
[0089] Please refer to Figure 1 , Figure 3 and Figure 7, in an embodiment of the present application, the light therapy device 100 further includes a first end 50 and a second end 60 disposed at opposite ends of the housing 10. The first end 50 is used for snap - connection with the second end 60 of another light therapy device; a first conductive electrode 71 is provided on the first end 50, and a second conductive electrode 72 for abutting and conducting with the first conductive electrode 71 of another light therapy device is provided on the second end 60; the light therapy device 100 further includes a driving board 73 for driving the light source 30. The driving board 73 is installed in the housing 10, and the light source 30, the first conductive electrode 71, and the second conductive electrode 72 are electrically connected to the driving board 73.
[0090] In this way, the snap - connection design of the first end 50 and the second end 60 enables multiple light therapy devices 100 to be connected to each other, realizing a modular connection method and forming a larger treatment unit. Users can freely combine multiple light therapy devices 100 according to needs to increase the coverage area of the treatment area to meet different treatment requirements. At the same time, the snap - connection design makes the light therapy device 100 easy to disassemble and assemble, convenient to carry and store, and simplifies the maintenance and repair process of the device.
[0091] In this embodiment, please refer to Figure 1 , Figure 3 , Figures 6 to 9 , on the first end 50, a first chute 51 and a second chute 52 for the second end 60 to be inserted and connected are provided. The first chute 51 is arranged along the length direction of the first end 50, the second chute 52 is arranged along the circumferential direction of the first end 50, and a claw 53 is provided in the second chute 52; a holding arm 81 is provided on the second end 60. When the holding arm 81 is inserted into the first chute 51, the second end 60 can move along the length direction of the first end 50 and connect or separate from the first end 50; when the holding arm 81 is inserted into the second chute 52, the second end 60 can rotate relative to the first end 50 and make the claw 53 clamp or release the holding arm 81.
[0092] Specifically, please refer to Figure 6 and Figure 7 , the first chute 51 and the second chute 52 are L - shaped and are provided on the outer peripheral surface of the first end 50. The second end 60 includes a docking cavity 601, and a holding arm 81 protrudes from the cavity wall of the docking cavity 601.
[0093] Specifically, please refer to Figures 7 to 9, the second end 60 includes a connecting member 61, a mounting base 62, and a mating member 63. The mounting base 62 includes two mounting cavities 622 separated by a mounting wall 621. The connecting member 61 is partially located in the receiving space, and the first end of the connecting member 61 is fixedly connected to the housing 10 by screws. The mounting base 62 covers the housing 10, and the second end of the connecting member 61 abuts against the mounting wall 621. The mating member 63 is disposed in the other mounting cavity 622, and the mating member 63 includes the aforementioned docking cavity 601. The connecting member 61, the mounting base 62, and the mating member 63 are fixedly connected to each other by screws arranged along the axial direction of the housing 10.
[0094] It can be understood that the diameter of the mounting base 62 is greater than the outer diameter of the housing 10, and the mating member 63 is embedded in the corresponding mounting cavity 622. When the first end 50 and the second end 60 are docked, the first end 50 is embedded in the docking cavity 601 of the mating member 63.
