[0002] Camping lights are lighting devices designed specifically for camping scenarios. They provide basic lighting functions to meet the lighting needs of campers during outdoor activities. They are usually small in size and lightweight, making them easy to carry and store, and suitable for complex and changeable outdoor environments.
[0003] Camping lights consist of a housing, a light-transmitting cover, and a light panel. The light panel is installed within a sealed space enclosed by the housing and the light-transmitting cover, and the light emitted by the light panel fills the entire light-transmitting cover. However, because the light panel generates a lot of heat during the lighting process, and the light panel lacks a heat dissipation design, its heat dissipation performance is poor. Increased temperature can damage the light panel, affecting its lifespan, and in severe cases, causing it to burn out. Therefore, improvements are urgently needed. Utility Model Content
[0004] Therefore, it is necessary to provide a lighting device that can enhance the heat dissipation performance of the lamp panel, so as to effectively prevent the lamp panel from being damaged or burned due to excessive temperature, and extend the service life of the lamp panel.
[0005] The embodiments of this application achieve the above objectives through the following technical solutions.
[0006] This application provides a lighting device, which includes a housing and a lamp plate. The housing includes a receiving section with an increasing diameter along its axial direction. The inner peripheral wall of the receiving section is provided with a plurality of heat dissipation protrusions arranged at intervals along its circumference. The lamp plate is installed in the receiving section, and the outer periphery of the lamp plate abuts against each of the heat dissipation protrusions.
[0007] In one embodiment, each of the heat dissipation protrusions has a first position and a second position spaced apart along the extension direction of the receiving segment, the thickness of the first position is less than the thickness of the second position, and the outer periphery of the lamp plate abuts against each of the first positions.
[0008] In one embodiment, the outer peripheral wall of the receiving section is provided with a plurality of heat dissipation recesses arranged at intervals along its circumference, and each heat dissipation recess is positioned opposite to the corresponding heat dissipation protrusion.

[0010] In one embodiment, the lighting device further includes a light-transmitting cover that covers the end of the receiving section with a larger diameter, and the heat dissipation protrusion is provided with a heat-conducting element that abuts against the light-transmitting cover.
[0011] In one embodiment, the heat-conducting element is provided with an abutment notch, which abuts against the end corner of the inner peripheral wall of the light-transmitting cover.
[0012] In one embodiment, the housing further includes a light-emitting section connected to the larger diameter end of the receiving section, the inner peripheral wall of the light-emitting section abutting against the outer peripheral wall of the light-transmitting cover, and the heat-conducting element abutting against the inner peripheral wall of the light-transmitting cover to clamp and fix the light-transmitting cover.

[0018] Compared with the prior art, the embodiments of this application have the following advantages: In this application, by setting the outer periphery of the lamp board to abut against each heat dissipation protrusion, only a part of the outer periphery of the lamp board abuts against the heat dissipation protrusion, while the rest of the lamp board is exposed in the internal space of the receiving section. This reduces the contact area between the lamp board and other parts in the receiving section, thereby enhancing the heat dissipation performance of the lamp board and effectively preventing the lamp board from being damaged or burned due to excessive temperature, thus extending the service life of the lamp board.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0033] This application provides a lighting device in which multiple heat dissipation protrusions are spaced apart along the circumference of the accommodating section on the inner peripheral wall of the accommodating section. A lamp plate is installed in the accommodating section with its outer periphery abutting against each heat dissipation protrusion. This means that the lamp plate only abuts against the heat dissipation protrusions through a portion of its outer periphery, while the rest of the lamp plate is exposed in the internal space of the accommodating section. This reduces the contact area between the lamp plate and other parts of the accommodating section, thereby enhancing the heat dissipation performance of the lamp plate. This effectively prevents the lamp plate from being damaged or burned due to excessive temperature, and extends the service life of the lamp plate.
[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0035] Please see Figure 1 This application provides a lighting device 100, which includes a housing 10 and a lamp panel 20.
[0036] The housing 10 includes a receiving section 11, which provides a receiving space for the lamp panel 20. The diameter of the receiving section 11 increases progressively along its axial direction, so that the receiving section 11 is flared, having one end with a larger diameter and one end with a smaller diameter. Obviously, there are many ways to form the receiving section 11. The receiving section 11 can be formed by a single flared structural member, or it can be formed by connecting multiple flared structural members sequentially (in this article, "multiple" refers to at least two). No specific limitation is made here.
[0037] The inner peripheral wall of the receiving section 11 is provided with a plurality of heat dissipation protrusions 111 arranged at intervals along its circumference. The lamp plate 20 is installed in the receiving section 11, and the outer periphery of the lamp plate 20 abuts against each heat dissipation protrusion 111. Specifically, the outer periphery of the lamp plate 20 abuts against the surface of each heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11.
[0038] It is worth mentioning that each heat dissipation protrusion 111 extends circumferentially along the receiving section 11, and also extends along the inclined direction of the inner peripheral wall of the receiving section 11, so that each heat dissipation protrusion 111 is arranged in a fan shape. This increases the surface area of the heat dissipation protrusion 111 exposed within the receiving section 11, facilitating the transfer of heat from the lamp panel 20 to the heat dissipation protrusion 111 for heat dissipation. Furthermore, each heat dissipation protrusion 111 can also be arranged in other shapes such as triangle, square, circle, or oval. Obviously, the heat dissipation protrusion 111 can be made of other heat dissipation materials such as PC (polycarbonate), PET (polyethylene terephthalate), aluminum alloy, or carbon fiber, which can enhance the heat dissipation effect of the heat dissipation protrusion 111.
[0039] Specifically, please refer to Figure 1 and Figure 2The corner of the outer peripheral wall of the lamp plate 20 abuts against the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11. This minimizes the contact area between the lamp plate 20 and the heat dissipation protrusion 111, increases the surface area of the lamp plate 20 exposed in the internal space of the receiving section 11, and thus enhances the heat dissipation effect of the lamp plate 20. Alternatively, in other embodiments, the shape of the outer peripheral wall of the lamp plate 20 can be adapted to match the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11, so that the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11 and the outer peripheral wall of the lamp plate 20 are in surface-to-surface contact.
[0040] In this embodiment, the heat dissipation protrusion 111 and the receiving section 11 are integrally formed, which enhances the stability of the heat dissipation protrusion 111. In other embodiments, the heat dissipation protrusion 111 and the receiving section 11 can also be set as two independent components. The two components can be fixed by means of ultrasonic welding, bonding or other fixed connection, or the two components can be fixed by means of detachable connection such as plug-in, snap-fit 121 connection, magnetic connection, threaded connection or other detachable connection.
[0041] In this embodiment, four heat dissipation protrusions 111 are provided, and the four heat dissipation protrusions 111 are evenly spaced along the circumference of the receiving section 11. This arrangement allows the heat from the lamp panel 20 to be evenly transferred to the four heat dissipation protrusions 111 along its circumference, which is beneficial for uniform heat dissipation of all parts of the lamp panel 20. In other embodiments, the heat dissipation protrusions 111 may also be three, five, or other values, and all the heat dissipation protrusions 111 may also be arranged at non-uniform intervals along the circumference of the receiving section 11.
[0042] Furthermore, in this embodiment, the inclination angle of the inner peripheral wall of the receiving segment 11 is the same as that of the outer peripheral wall of the receiving segment 11, both being 142.48 degrees. This enhances the dispersion effect of the light emitted by the lamp panel 20. In other embodiments, the inclination angle of the inner peripheral wall of the receiving segment 11 may be different from that of the outer peripheral wall of the receiving segment 11. For example, the inclination angle of the inner peripheral wall of the receiving segment 11 may be 140 degrees, and the inclination angle of the outer peripheral wall of the receiving segment 11 may be 130 degrees.
[0043] Furthermore, in this embodiment, please refer to Figure 1 and Figure 2The lamp plate 20 has an LED 21 at the end facing the receiving section 11 with a larger diameter, so that the light emitted by the LED 21 can be diffused through the receiving section 11. In other embodiments, the LED 21 can also be located at the end of the lamp plate 20 facing the receiving section 11 with a smaller diameter, so that the light emitted by the LED 21 can be focused through the receiving section 11. By way of example and not limitation, the number of LEDs 21 can be one or more. When there are multiple LEDs 21, the multiple LEDs 21 can be arranged in a regular manner such as a rectangular array or a circular array, or they can be arranged in an irregular manner.
[0044] Further, please refer to Figure 1 and Figure 3 The inner circumferential wall of the receiving section 11 is provided with three inserts 112 evenly spaced along its circumference. The lamp plate 20 is provided with three through holes 22, each through hole 22 being fixed to the corresponding insert 112 by bolts. This allows the fixing force on the lamp plate 20 to be arranged in a triangular pattern, thereby enhancing the stability of the lamp plate 20. Furthermore, the three inserts are connected to three heat dissipation protrusions 111, allowing the heat from the lamp plate 20 to be transferred to the heat dissipation protrusions 111 via the inserts 112, which is beneficial for the heat dissipation of the lamp plate 20.
[0045] Through the above technical solution, the lamp panel 20 is arranged so that its outer periphery abuts against each heat dissipation protrusion 111, so that only a part of the outer periphery of the lamp panel 20 abuts against the heat dissipation protrusion 111, while the rest of the lamp panel 20 is exposed in the internal space of the accommodating section 11. This reduces the contact area between the lamp panel 20 and other parts of the accommodating section 11, thereby enhancing the heat dissipation performance of the lamp panel 20. This effectively prevents the lamp panel 20 from being damaged or burned due to excessive temperature, and extends the service life of the lamp panel 20.
[0046] In use, a portion of the heat from the lamp panel 20 is first transferred to the housing section 11 via the heat dissipation protrusion 111, and then transferred to the external environment via the housing section 11. Another portion of the heat from the lamp panel 20 is directly transferred to the internal space of the housing section 11, and then transferred to the external environment via the housing section 11. This enhances the heat dissipation performance of the lamp panel 20.
[0047] Considering that the heat dissipation protrusion 111 has a certain thickness, where thickness refers to the distance between the surface of the heat dissipation protrusion 111 connecting to the inner peripheral wall of the receiving section 11 and the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11, if the heat dissipation protrusion 111 has different thicknesses, the outer periphery of the lamp plate 20 abuts against the thinner portion of the heat dissipation protrusion 111, which can accelerate the diffusion rate of heat on the heat dissipation protrusion 111. Therefore, please refer to... Figure 1 and Figure 4In one embodiment of this application, each heat dissipation protrusion 111 has a first position and a second position that are spaced apart along the extension direction of the receiving section 11. The thickness of the first position is less than the thickness of the second position. The outer periphery of the lamp plate 20 abuts against each of the first positions, so that the outer periphery of the lamp plate 20 abuts against the position with the smaller thickness on the heat dissipation protrusion 111.
[0048] Specifically, the thickness of the heat dissipation protrusion 111 increases first and then decreases from the end with the smaller diameter of the receiving section 11 to the end with the larger diameter of the receiving section 11, with the increase being much greater than the decrease. This facilitates the contact between the heat dissipation protrusion 111 and the end face of the light-transmitting cover 30, which will be described below. In other embodiments, the thickness of the heat dissipation protrusion 111 may simply increase from the end with the smaller diameter of the receiving section 11 to the end with the larger diameter of the receiving section 11, or it may simply decrease from the end with the smaller diameter of the receiving section 11 to the end with the larger diameter of the receiving section 11.
[0049] Furthermore, the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11 is formed as a raised curved surface, which increases the surface area of the heat dissipation protrusion 111 and thus enhances its heat dissipation effect. In other embodiments, the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11 may also be formed as a plane.
[0050] In this embodiment, the thicker second position is located between the thinner first position and the larger diameter end of the receiving section 11, thus facilitating the contact between the heat dissipation protrusion 111 and the end face of the light-transmitting cover 30, which will be described below. In other embodiments, the thinner first position may be located between the thicker second position and the larger diameter end of the receiving section 11.
[0051] To further enhance the heat dissipation effect of the heat dissipation protrusion 111, please refer to... Figure 1 and Figure 5 In one embodiment of this application, the outer peripheral wall of the receiving section 11 is provided with a plurality of heat dissipation recesses 113 arranged at intervals along its circumference. Each heat dissipation recess 113 is positioned opposite to a corresponding heat dissipation protrusion 111. In this way, by providing the heat dissipation recesses 113, on the one hand, the wall thickness at the position on the receiving section 11 that connects to each heat dissipation protrusion 111 can be reduced, that is, the path of heat on the heat dissipation protrusion 111 transferred to the external environment through the receiving section 11 can be reduced, thereby accelerating the speed at which heat on the heat dissipation protrusion 111 is transferred to the external environment. On the other hand, the surface area at the position on the outer peripheral wall of the receiving section 11 that is opposite to each heat dissipation protrusion 111 can be increased, thereby also accelerating the speed at which heat on the heat dissipation protrusion 111 is transferred to the external environment.
[0052] Specifically, the shape of the bottom wall of the heat dissipation recess 113 is the same as the shape of the surface of the inner peripheral wall of the heat dissipation protrusion 111 facing away from the receiving section 11, which can increase the surface area of the bottom wall of the heat dissipation recess 113 and thus enhance the heat dissipation effect of the heat dissipation recess 113.
[0053] Considering that the lighting device 100 is also equipped with a light-transmitting cover 30, and the light emitted by the lamp panel 20 is irradiated through the light-transmitting cover 30, the light-transmitting cover 30 is prone to overheating after prolonged irradiation. Therefore, in order to effectively prevent the light-transmitting cover 30 from overheating after prolonged irradiation, please refer to... Figure 1 and Figure 2 In one embodiment of this application, the lighting device 100 further includes a light-transmitting cover 30, which covers the end of the receiving section 11 with a larger diameter. The end face of the light-transmitting cover 30 abuts against each heat dissipation protrusion 111, so that some of the heat from the light-transmitting cover 30 can be transferred to the heat dissipation protrusion 111 to achieve heat dissipation, thereby effectively preventing the light-transmitting cover 30 from overheating after prolonged irradiation.
[0054] Specifically, please refer to Figure 2 and Figure 4 Each heat dissipation protrusion 111 has a smaller diameter end away from the receiving section 11 on one side, which is formed as an abutment plane 111'. The end face of the light-transmitting cover 30 abuts against each abutment plane 111', which facilitates the transfer of heat from the light-transmitting cover 30 to the heat dissipation protrusion 111.
[0055] To further enhance the heat dissipation effect of the light-transmitting cover 30, please refer to... Figure 2 and Figure 4 In one embodiment of this application, the heat dissipation protrusion 111 is provided with a heat-conducting element 1111, which abuts against the light-transmitting cover 30. This allows the heat from the light-transmitting cover 30 to be transferred to the heat dissipation protrusion 111 through the heat-conducting element 1111, thereby further enhancing the heat dissipation effect of the light-transmitting cover 30.
[0056] Specifically, the heat-conducting element 1111 is disposed on the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11, and the heat-conducting element 1111 abuts against the inner peripheral wall of the light-transmitting cover 30, thus facilitating the transfer of heat from the light-transmitting cover 30 to the heat dissipation protrusion 111 via the heat-conducting element 1111. Furthermore, the heat-conducting element 1111 is disposed in a sheet-like manner, which enhances the heat transfer effect of the heat-conducting element 1111. In other embodiments, the heat-conducting element 1111 may also be disposed at the end of the heat dissipation protrusion 111 in the circumferential direction of the receiving section 11, and the heat-conducting element 1111 may also abut against the end face of the light-transmitting cover 30.
[0057] Further, please refer to Figure 2 and Figure 4The heat-conducting component 1111 is provided with an abutment notch 1111', which abuts against the end corner of the inner peripheral wall of the light-transmitting cover 30. This arrangement allows the heat from the light-transmitting cover 30 to be transferred to the heat-conducting component 1111 through the abutment notch 1111', and also allows the light-transmitting cover 30 to be supported through the abutment notch 1111', thereby enhancing the stability of the light-transmitting cover 30.
[0058] In this embodiment, the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11 is provided with two spaced heat-conducting elements 1111 on the circumferential upward side of the receiving section 11, and the surface of the heat dissipation protrusion 111 facing away from the inner peripheral wall of the receiving section 11 is also provided with two spaced heat-conducting elements 1111 on the circumferential upward side of the receiving section 11. This can accelerate the speed at which the heat of the light-transmitting cover 30 is transferred to the heat dissipation protrusion 111.
[0059] For easier fixing of the light-transmitting cover 30, please refer to [link / reference]. Figure 1 and Figure 2 In one embodiment of this application, the housing 10 further includes a light-emitting section 12, which is connected to the larger end of the receiving section 11. The inner peripheral wall of the light-emitting section 12 abuts against the outer peripheral wall of the light-transmitting cover 30, and the heat-conducting element 1111 abuts against the inner peripheral wall of the light-transmitting cover 30 to clamp and fix the light-transmitting cover 30. With this arrangement, the light-transmitting cover 30 can be clamped and fixed together by the heat-conducting element 1111 and the light-emitting section 12, making it convenient to fix the light-transmitting cover 30.
[0060] Specifically, the light-emitting section 12 and the receiving section 11 are integrally formed, which can enhance the connection strength between the light-emitting section 12 and the receiving section 11.
[0061] Further, please refer to Figures 1 to 3 The outer peripheral wall of the light-transmitting cover 30 is provided with a plurality of fasteners 301 arranged at intervals along its circumference, and the inner peripheral wall of the light-emitting section 12 is provided with a plurality of snap fasteners 121 arranged at intervals along its circumference. Each snap fastener 121 engages with the corresponding fastener 301, thereby enhancing the stability of the light-transmitting cover 30. Furthermore, the outer peripheral wall of the light-transmitting cover 30 is also provided with a first sealing groove 302 extending along its circumference. A first sealing ring 303 is provided within the first sealing groove 302 and engages therewith. The outer peripheral wall of the first sealing ring 303 elastically abuts against the inner peripheral wall of the light-emitting section 12, thereby enhancing the sealing between the outer peripheral wall of the light-transmitting cover 30 and the inner peripheral wall of the light-emitting section 12.
[0062] And, please see Figure 2 The side of the light-emitting section 12 away from the receiving section 11 has four anti-collision protrusions 122 integrally formed along its circumference. This arrangement makes the light-transmitting cover 30 located inside the four anti-collision protrusions 122. When the lighting device 100 is accidentally dropped, the anti-collision protrusions 122 will collide to protect the light-transmitting cover 30.
[0063] In other embodiments, the housing 10 may also consist only of the receiving section 11, with the light-transmitting cover 30 directly covering the larger end of the receiving section 11.
[0064] Considering that the lighting fixture 100 is equipped with a switch 40 for controlling the opening and closing of the lamp panel 20, for the convenience of disassembling and assembling the switch 40 of the lighting fixture 100, please refer to [link / reference needed]. Figure 2 , Figure 3 as well as Figure 6 In one embodiment of this application, the lamp panel 20 is provided with two insertion ports 23, and the housing 10 also includes a connecting section 13, which is connected to the smaller end of the receiving section 11; the lighting device 100 also includes a switch 40, which is located in the connecting section 13 and is provided with two plugs 41. Each plug 41 extends along the axial direction of the connecting section 13, and each plug 41 has a bent insertion head 411 at the end away from the switch 40. Each insertion head 411 is elastic and is inserted into the corresponding insertion port 23.
[0065] With the above technical solution, when installing switch 40, firstly, press the two plug heads 411 towards each other, then insert the two plug heads 411 into the two plug holes 23 respectively, and then release the two plug heads 411. Under the action of their own elastic force, the two plug heads 411 abut against the two plug holes 23 respectively, thus completing the installation of switch 40; when disassembling switch 40, firstly, press the two plug heads 411 away from each other, then insert the two plug heads 411 out of the two plug holes 23 respectively, thus completing the disassembly of switch 40.
[0066] Further, please refer to Figure 6 The lamp board 20 is also provided with two conductive holes 24, and the switch 40 is provided with two conductive elements 42. Each conductive element 42 extends along the axial direction of the connecting section 13. The end of each conductive element 42 away from the switch 40 is inserted into the corresponding conductive hole 24, which makes the electrical connection between the lamp board 20 and the switch 40 convenient.
[0067] Considering that the lighting device 100 is also provided with a button 60 for pressing the switch 40, please refer to [link / reference needed] for easy installation and removal of the button 60. Figures 1 to 3 as well as Figure 7 In one embodiment of this application, the lighting device 100 further includes a housing 50 and a button 60. The housing 50 is fitted over the connecting section 13 and has a clearance opening 501. The button 60 is sandwiched between the inner peripheral wall of the housing 50 and the outer peripheral wall of the connecting section 13 and is exposed through the clearance opening 501. The button 60 and the switch 40 are positioned opposite each other. The connecting section 13 forms a through opening 131 and a pressing member 132 at the position between the button 60 and the switch 40. The pressing member 132 is elastic and located inside the through opening 131.
[0068] Specifically, please refer to Figure 3 and Figure 7 The button 60 has a pressing head on the side facing the switch 40 for pressing the pressing member 132, which makes it convenient to press the pressing head of the button 60.
[0069] With the above technical solution, the sleeve 50 and the connecting section 13 together clamp and fix the button 60, thus completing the installation of the button 60. Moving the sleeve 50 away from the receiving section 11 until the sleeve 50 is detached from the connecting section 13 releases the constraint on the button 60, thus completing the disassembly of the button 60. During use, when a pressing force is applied to the button 60, the pressing force is transmitted to the switch 40 through the pressing member 132, thereby pressing the switch 40 and causing the pressing member to undergo elastic deformation; when the pressing force applied to the button 60 is removed, the pressing member 132, under the action of its own rebound force, drives the button 60 to return to its initial state.
[0070] Further, please refer to Figure 1 , Figure 2 as well as Figure 7 The outer peripheral wall of the connecting section 13 is provided with a mounting groove 133. The mounting groove 133 is provided through the side away from the receiving section 11. The through opening 131 is provided at the bottom of the mounting groove 133. The button 60 includes a first section 61 and a second section 62 connected to the first section 61. The width of the second section 62 is greater than the width of the first section 61. The first section 61 cooperates with the clearance opening 501, and the second section 62 cooperates with the mounting groove 133. This arrangement allows the first section 61 of the button 60 to be fixed to the housing 50, and the second section 62 of the button 60 to pass through the through position of the mounting groove 133 along the axial direction of the connecting section 13. This allows the button 60 and the housing 50 to be disassembled and assembled together from the connecting section 13.
[0071] Please see Figure 3 In one embodiment of this application, the lighting device 100 further includes a plug 70, which is connected to the end of the connecting section 13 facing away from the receiving section 11. The connection method between the plug 70 and the connecting section 13 is set in accordance with the fixed connection or detachable connection method in the above embodiments, and will not be described in detail here.
[0072] Further, please refer to Figure 2 , Figure 7 as well as Figure 8The inner peripheral wall of the housing 50 is provided with a first annular protrusion 502 surrounding the clearance opening 501. The outer peripheral wall of the connecting section 13 is provided with a second annular protrusion 134 extending circumferentially near the receiving section 11. The first annular protrusion 502 is sandwiched between the second annular protrusion 134 and the plug 70, which can enhance the fixing strength of the housing 50. In addition, the outer peripheral wall of the second annular protrusion 134 is provided with a second sealing groove 1341. A second sealing ring 135 is provided in the second sealing groove 1341 and it mates with it. The outer peripheral wall of the second sealing ring 135 elastically abuts against the inner peripheral wall of the housing 50, which can enhance the sealing between the inner peripheral wall of the housing 50 and the outer peripheral wall of the connecting section 13.
[0073] Furthermore, please refer to Figure 2 and Figure 7 The outer peripheral wall of the plug 70 is provided with a third sealing groove 701, and a third sealing ring 71 that cooperates with it is provided in the third sealing groove 701. The outer peripheral wall of the third sealing ring 71 elastically abuts against the inner peripheral wall of the housing 50, which can enhance the sealing between the inner peripheral wall of the housing 50 and the outer peripheral wall of the plug 70.
[0074] Please see Figure 9 and Figure 10 This application also provides an outdoor device 1000, which includes a lighting device 100 and a handheld host 200 as described above. The lighting device 100 and the handheld host 200 are detachably connected. Specifically, the handheld host 200 is provided with a socket 210 for the plug 70 to be inserted, thus facilitating the assembly and disassembly of the handheld host 200 and the lighting device 100. Furthermore, the detachable connection between the lighting device 100 and the handheld host 200 can also be achieved through the detachable connection method described in the above embodiments.
