DETAILED DESCRIPTION

[0029] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Example 1

[0033] Combine Figures 1 to 6, schematically shows the heat dissipation structure of the present invention, including a first shell 10 and a second shell 20 . The material of the first shell 10 can be the same as or different from that of the second shell 20 .

[0034] like Figure 1 and Figure 3 A light-emitting element 41 is provided in the first shell 10 and is fitted therewith. A plurality of heat dissipation fins 11 are provided on the first shell 10. The light-emitting element 41 is used for illuminating. The heat generated when the light-emitting element 41 emits light can be conducted to the first shell 10. The heat dissipation fins 11 provided on the first shell 10 are used to assist the first shell 10 in dissipating heat to the outside, thereby improving the heat dissipation efficiency. The first shell 10 is preferably made of metal material, such as aluminum alloy, which not only has higher thermal conductivity than plastic material, but is also easy to manufacture by extrusion molding, and has low production cost.

[0035] like Figure 3 The second housing 20 houses a power supply unit 30. Of course, electronic components such as a control circuit board may also be located within the second housing 20. Separating the heat-generating light-emitting element 41 and the power supply unit 30 from the first housing 10 and the second housing 20 prevents the heat dissipated by each from affecting the other, significantly extending the service life of both. Furthermore, the high heat dissipation performance of these separate arrangements allows the heat dissipation structure to support higher-power light-emitting elements 41, further enhancing the product's market competitiveness.

[0036] Combine Figure 2 and Figure 3 As shown, the interior of the first shell 10 and the interior of the second shell 20 are connected by a wire channel 50. A cable connecting the light-emitting element 41 and the power supply device 30 is provided in the wire channel 50. The cable is used to transmit electrical energy to the light-emitting element 41. Of course, existing data transmission lines can also be arranged in the wire channel 50 according to actual needs. The function of the wire channel 50 is mainly to arrange various wires to prevent various wires from being exposed outside the first shell 10 or the second shell 20, thereby improving the service life of various wires including the cable. Moreover, due to its small channel cross-sectional area, the heat conduction efficiency of the wire channel 50 is extremely limited. Therefore, the heat in the first shell 10 or the heat in the second shell 20 is difficult to be transferred to the other side through the wire channel 50, which can reduce the mutual influence caused by the heat of the light-emitting element 41 and the power supply device 30.

[0037] like Figure 4The end of the second housing 20 is provided with a mounting cavity 21, which is arranged opposite the first housing 10. The bottom wall of the mounting cavity 21 is provided with the aforementioned wire passage 50. The end of the first housing 10 is detachably inserted into the mounting cavity 21, thereby making the connection between the first housing 10 and the second housing 20 more stable. The heat dissipation structure also includes a sealing ring 211 located within the mounting cavity 21. The sealing ring 211 defines a clearance hole 211a, and the wire passage 50 is located within the clearance hole 211a. The two ends of the sealing ring 211 respectively abut against the bottom wall of the mounting cavity 21 and the end face of the first housing 10. The sealing ring 211 can improve the waterproof performance between the mounting cavity 21 and the first housing 10. In addition, the end of the first housing 10 is inserted into the mounting cavity 21, which can significantly improve the waterproof performance and airtightness of the connection between the first housing 10 and the second housing 20.

[0038] More specifically, the wire-passing channel 50 includes a receiving cavity 51 and a wire-passing hole 52. The bottom wall of the receiving cavity 51 is provided with a wire-passing hole 52 connected to the interior of the second shell 20. The receiving cavity 51 is arranged toward the first shell 10. The cables passing through the second shell 20 can be bent and received in the receiving cavity 51 after passing through the wire-passing hole 52. When there are multiple cables, this structure can avoid multiple cables passing through the wire-passing hole 52 and being directly connected to multiple light-emitting elements 41, which would cause the cables in the first shell 10 to be arranged in a messy manner.

[0039] Furthermore, the sealing ring 211 defines a guide hole 211b, and a guide post 212 is provided within the mounting cavity 21. The guide post 212 extends through the guide hole 211b. The guide post 212 and the guide hole 211b restrict the relative position of the sealing ring 211 and the mounting cavity 21, facilitating a more appropriate insertion of the sealing ring 211 into the mounting cavity 21. Furthermore, the ends of the guide posts 212 can be provided with connection holes, as required. The first housing 10 can be connected to the second housing 20 by inserting existing fasteners such as screws through the connection holes. In this embodiment, multiple guide posts 212 are provided, and the multiple guide posts 212 are parallel to each other. The number of guide holes 211b matches the number of guide posts 212, and each guide post 212 corresponds to a corresponding guide hole 211b. The provision of multiple guide posts 212 and multiple guide holes 211b allows for more precise positioning of the sealing ring 211 and improves the stability of the connection between the first housing 10 and the second housing 20.

[0040] In this embodiment, the first housing 10 includes a bottom plate 12 and two side plates 13 respectively provided on both sides of the bottom plate 12. Figure 3 and Figure 5As shown, the side panels 13 are preferably arranged perpendicularly to the base panel 12, resulting in a U-shaped cross-section of the first housing 10. The light-emitting element 41 and the heat sink fins 11 are located on opposite sides of the base panel 12, with the light-emitting element 41 located within the U-shaped portion of the first housing 10. The first housing 10 is covered with a transparent mask, the two sides of which are connected to the two side panels 13 to provide protection for the light-emitting element 41. A plurality of heat sink fins 11 are provided, and their extension direction is parallel to the length of the base panel 12. This structure facilitates aluminum extrusion molding, allowing for low-cost production of the first housing 10 and reducing product costs.

[0041] The second shell 20 is provided with an opening, and a door body 22 is rotatably connected to one side of the opening. When the door body 22 is closed, the opening can be covered. The setting of the door body 22 is convenient for installation and maintenance personnel to open and install and maintain components such as the power supply device 30 in the second shell 20.

[0042] In addition, the heat dissipation structure further includes a first mounting bracket 60 and a second mounting bracket 70. Figure 1 The first mounting bracket 60 is connected to the first shell 10, and the second mounting bracket 70 is connected to the second shell 20. The first mounting bracket 60 and the second mounting bracket 70 can be connected to the building to install the heat dissipation structure in an existing tunnel. The first shell 10 and the second shell 20 are respectively provided with their own mounting brackets, which can share the weight of the first shell 10 and the second shell 20 to prevent one shell from being connected to the tunnel alone, resulting in the connection between the first shell 10 and the second shell 20 being subjected to excessive bending moment. Figure 7 At least one heat dissipation fin 11 is provided with a mounting groove 111, and the opening of the mounting groove 111 is set away from the first shell 10. A clamping block (not shown) is movably provided at the end of the first mounting bracket 60, and the clamping block is detachably embedded in the mounting groove 11. The distance between the clamping block and the first mounting bracket 60 can be adjusted by a thread. When the distance between the two is reduced, the clamping block and the first mounting bracket 60 clamp the opening of the mounting groove 111 to prevent the first mounting bracket 60 and the first shell 10 from moving relative to each other; when the distance between the clamping block and the first mounting bracket 60 is increased, the clamping block can slide in the mounting groove 111 to adjust the relative position between the first mounting bracket 60 and the first shell 10.

[0043] Example 2

[0044] Combine Figure 1 、 Figure 3 and Figure 6As shown, this embodiment provides a lighting device, including an LED module 40 and the heat dissipation structure as described above. The LED module 40 is located in the first shell 10, and the LED module 40 is attached to the inner wall surface of the first shell 10. The LED module 40 is provided with a plurality of light-emitting elements 41 arranged in a matrix. The lighting device arranges the light-emitting elements 41 and the power supply device 30 separately, which can avoid the heat generated by the light-emitting elements 41 and the power supply device 30 from affecting each other, thereby improving the service life of the product.

[0045] To sum up, the light-emitting element 41 is attached to the first shell 10, and the first shell 10 is provided with a heat dissipation fin 11 for heat dissipation. The power supply device 30 is arranged in the second shell 20, so that the light-emitting element 41 with higher heat generation and the power supply device 30 are dispersed to avoid the heat generated by the two from affecting each other and reducing the service life of the two. At the same time, the arrangement structure can also be used to set a higher power light-emitting element 41, thereby improving the market competitiveness of the product. The cable connecting the light-emitting element 41 and the power supply device 30 is arranged in the wire channel 50 between the first shell 10 and the second shell 20. The built-in cable is protected from the influence of the external environment and has a longer service life.
