DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort are within the protection scope of the present application.

[0025] It is to be understood that the terminology used herein such as first and second, and the like, is merely intended to differentiate one entity or action from another without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the presence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0026] The embodiment of the present application provides an LED light bar module and a far image reading and writing equipment frame, and solves the problem of difficult heat dissipation of the light bar caused by space limitation when the far image reading and writing equipment frame is provided with the LED light bar.

[0027] The technical solutions in the embodiment of the present application are used to solve the above technical problems, and the general idea is as follows:

[0028] The far image reading and writing equipment can change a close-range image into a far-distance virtual image based on an optical design principle and a free-form surface mirror technology, and perform magnifying imaging. In a passive far image reading and writing equipment, imaging is performed through reflection and diffuse reflection of light. In order to ensure imaging quality, an LED light bar needs to be arranged at an end of the far image reading and writing equipment frame to increase the brightness of a surface of an object to be magnified and imaged.

[0029] However, when the LED light bar works, not all the electric energy is converted into light energy. According to the law of conservation of energy, part of the electric energy will inevitably be converted into heat energy. This is because when the electrons and holes in the LED chip recombine, in addition to emitting light energy in the form of photons, there is a non-radiative recombination process, which releases heat.

[0030] Due to the limited space of the end of the far image reading and writing equipment frame, the LED light bar cannot effectively dissipate heat and is seriously overheated. Too much heat will affect the adhesion strength of the LED light bar and cause the LED light bar to fall off, and also reduce the service life of the LED light bar, thereby affecting the use experience of the far image reading and writing equipment.

[0031] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings of the specification and specific embodiments.

[0032] First, an LED light bar module provided by the embodiment of the present application will be introduced.

[0033] The LED lamp strip module provided by the embodiment of the present application comprises a mounting member and a heat dissipation part Figure 1 and Figure 2 The mounting member comprises a connecting support 1, the connecting support 1 is internally formed with a regular assembly cavity, and the outer peripheral surface is provided with a concave-convex patterned groove part; the heat dissipation part and the wall surface of the connecting support 1 enclose a clamping cavity A and comprise a connecting layer 2 and a heat exchange layer 3 which are stacked with each other, the connecting layer 2 is bonded with a heat-conducting silicone grease layer 4 on the side away from the heat exchange layer 3, and the LED lamp strip 5 is connected through the heat-conducting silicone grease layer 4.

[0034] It can be understood that the LED lamp strip 5 of the present application is located inside the assembly cavity of the connecting support 1, the LED lamp strip 5 is bonded and connected with the connecting layer 2 through the heat-conducting silicone grease layer 4, and the heat-conducting silicone grease layer 4 is beneficial to the heat conduction of the back of the LED lamp strip 5; the outer peripheral surface of the connecting support 1 is provided with a concave-convex patterned groove part, which can increase the heat dissipation area of the overall heat dissipation structure and is beneficial to heat dissipation.

[0035] Specifically, the heat exchange layer 3 comprises a heat-conducting hollow shell 31, the center position of the heat-conducting hollow shell 31 is provided with a first pipeline 32 corresponding to the wick position of the LED lamp strip 5 to introduce heat exchange working medium, in the length direction perpendicular to the first pipeline 32, the heat-conducting hollow shell 31 is further provided with at least one set of heat collecting members 33 and at least one set of second pipelines 34 inside in sequence, and the second pipeline 34 is communicated with the first pipeline 32 through a plurality of arc-shaped passages 35.

[0036] It can be understood that the heat-conducting hollow shell 31 of the heat exchange layer 3 is hollow inside, which is beneficial to air circulation; the first pipeline 32 and the second pipeline 34 inside the heat-conducting hollow shell 31 are communicated through the arc-shaped passages 35, which can form an internal line in the heat-conducting hollow shell 31 for the flow of heat exchange working medium, and can effectively eliminate the heat conducted by the LED lamp strip 5 after introducing the heat exchange working medium from the first pipeline 32.

[0037] It should be emphasized that the LED lamp strip 5 comprises a plurality of spaced-apart wicks along the length direction of the LED lamp strip 5, and since the first pipeline 32 corresponds to the position of the wick in space, the heat exchange working medium introduced into the first pipeline 32 can quickly exchange heat with the back area of the wick, and the cooling effect is fast.

[0038] Further, the heat collecting members 33 are located between the first pipeline 32 and the second pipeline 34 and are adjacent to the first pipeline 32 to be close to the wick of the LED lamp strip 5 in space, the center line of the arc-shaped passage 35 is a smooth curve and the center of curvature is directed to at least one adjacent heat collecting member 33.

[0039] In the embodiments of the present application, it can be understood that the heat collecting member 33 is arranged adjacent to the first pipeline 32, and the heat collecting member 33 is close to the lamp core of the LED lamp strip 5 in space, which can accelerate the absorption of heat in the surrounding area. The adjacent area of the heat collecting member 33 is also partially surrounded by the arc-shaped passage 35, and the heat exchange medium flowing in the arc-shaped passage 35 can achieve the effect of rapid heat dissipation.

[0040] In some embodiments, as shown in Figure 2 , the length direction of the first pipeline 32, the length direction of the second pipeline 34, and the interval arrangement direction of each group of heat collecting members 33 are consistent; along the length direction of the first pipeline 32, two adjacent arc-shaped passages 35 hold one heat collecting member 33 and form a concentrated heat exchange part to cover the corresponding heat collecting member 33.

[0041] In the embodiments of the present application, it can be understood that the heat collecting member 33 is located near the lamp core of the LED lamp strip 5 in space, which can absorb heat, and the heat in the adjacent area of the heat collecting member 33 will be concentrated to form a concentrated heat exchange part; along the length direction of the first pipeline 32, the heat collecting member 33 is located between two arc-shaped passages 35, and when the heat exchange medium flows in the arc-shaped passage 35, it can effectively exchange heat with the concentrated heat exchange part, thereby reducing the overall temperature of the heat exchange layer 3 and quickly relieving the local high temperature caused by the LED lamp strip 5.

[0042] In one example, please refer to Figure 2 , the inner diameter of the second pipeline 34 is smaller than the inner diameter of the first pipeline 32, and the second pipeline 34 and the heat collecting member 33 are both provided with two groups, and the two groups of second pipelines 34 and the two groups of heat collecting members 33 are symmetrically distributed on both sides of the first pipeline 32.

[0043] In another example, please refer to Figure 1 and Figure 2 , the number of heat collecting members 33 in each group is consistent with the number of lamp cores of the LED lamp strip 5, and on any cross section covering the centers of two heat collecting members 33 symmetric about the first pipeline 32, there is a center of a lamp core.

[0044] It can be understood that the heat collecting member 33 in each group of heat collecting members 33 corresponds to the lamp core one by one, and since there are two groups of heat collecting members 33, the number of heat collecting members 33 is twice the number of lamp cores; the center of a lamp core corresponds to the center of two coplanar heat collecting members 33, in other words, a lamp core corresponds to 2 adjacent heat collecting members 33 in space to absorb heat.

[0045] In some embodiments, as shown in Figure 1As shown, the patterned groove portion is arranged on both sides of the connecting support 1. On either side of the connecting support 1, the patterned groove portion includes a plurality of alternating spaced convex portions B and concave portions C, and the plurality of convex portions B are aligned away from the side of the assembly cavity. It can be understood that the outer circumferential surface of the connecting support 1 can significantly increase the area of the outer circumferential surface of the connecting support 1 by arranging a plurality of convex portions B and concave portions C, thereby increasing the heat dissipation area.

[0046] In some embodiments, the first pipe 32 and the second pipe 34 are both internally smooth, the two ends of the first pipe 32 are openable and one end is configured to be suitable for introducing a heat exchange medium, and the two ends of the second pipe 34 are closed. It can be understood that the heat exchange medium can be a gas or a liquid, i.e., heat management can be performed by a gas or a liquid. For example, the heat exchange medium can be an air flow, and the first pipe 32 can be externally connected to a fan to introduce low-temperature air flow to achieve heat exchange cooling.

[0047] In some embodiments, please refer to Figure 1 The heat dissipation portion further includes a special-shaped heat dissipation member 6, which includes a first side that is flat and a second side that is uneven. The first side of the special-shaped heat dissipation member 6 is connected to the heat-conducting shell 31 of the heat exchange layer 3. The second side of the special-shaped heat dissipation member 6 includes a plurality of heat-conducting branch segments 61 extending toward the clamping cavity A.

[0048] In the embodiments of the present application, it can be understood that the heat exchange layer 3, while being cooled by introducing a heat exchange medium, also conducts heat toward the abutting special-shaped heat dissipation member 6. The special-shaped heat dissipation member 6 is provided with a plurality of heat-conducting branch segments 61, and the heat-conducting branch segments 61 face the clamping cavity A, so that heat dissipation can be performed through a large heat dissipation area.

[0049] In one example, the plurality of heat-conducting branch segments 61 are spaced apart and correspond to different extension lengths. Each heat-conducting branch segment 61 has an arc-shaped tip D away from the heat-conducting shell 31. The outer contour surface of the arc-shaped tip D is convex toward the top of the clamping cavity A, which is opposite to the open side of the connecting support 1.

[0050] In some embodiments, the heat collecting member 33 is in a continuous columnar shape and is abuttingly attached to the inner wall of the heat-conducting shell 31 at both ends. The heat conductivity of the heat-conducting shell 31, the special-shaped heat dissipation member 6, and the connecting layer 2 is less than that of the heat collecting member 33.

[0051] In the embodiments of the present application, it can be understood that the height of the heat collecting member 33 is consistent with the height of the inner cavity of the heat-conducting shell 31, and the heat collecting member 33 is abuttingly attached to the inner wall of the heat-conducting shell 31, which can accelerate the speed of heat conduction outward.

[0052] In addition, the heat-conducting shell 31, the special-shaped heat-dissipating member 6 and the connecting layer 2 can be made of aluminum material, and the heat collecting member 33 can be made of copper material. The heat collecting member 33 can absorb heat faster and continue to conduct heat outward, and exchange heat with the heat exchange working medium flowing in the arc-shaped passage 35.

[0053] In some embodiments, the application also provides a far-field read-write device frame, which comprises the aforementioned LED light bar module located at the end of the far-field read-write device frame.

[0054] In summary, compared with the prior art, the application has the following beneficial effects:

[0055] 1. The LED light bar 5 of the application is connected to the connecting layer 2 through the heat-conducting silicone grease layer 4. The heat-conducting silicone grease layer 4 is beneficial to the heat conduction of the back of the LED light bar 5. The outer peripheral surface of the connecting support 1 is provided with a concave-convex patterned groove portion, which can increase the overall heat dissipation area of the heat dissipation structure and is beneficial to heat dissipation.

[0056] 2. The first pipeline 32 and the second pipeline 34 of the application are communicated through the arc-shaped passage 35, which can form an internal line for the flow of heat exchange working medium inside the heat-conducting shell 31. After the heat exchange working medium is introduced from the first pipeline 32, the heat conducted by the LED light bar 5 can be effectively eliminated.

[0057] 3. The heat collecting member 33 of the application is adjacent to the first pipeline 32.
