[0067] Various non-limiting embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0068] Indicative lighting equipment

[0069] like Figures 1 to 12 As shown, a lighting device according to an embodiment of this application is illustrated. The lighting device includes a main body and a light-emitting part mounted on the main body. The light-emitting part includes at least one light-emitting unit. In this embodiment, the light-emitting part has a special design. Therefore, a dedicated sealing device 40 is provided for this special design to ensure the sealing of the light-emitting part, thereby ensuring the normal operation of the lighting device. Accordingly, the lighting device includes a sealing device 40 mounted on the main body, and at least one light-emitting unit is mounted in the sealing device 40.

[0070] Specifically, in this embodiment, the main body includes a mounting carrier 10 and a power supply unit 20 held on the mounting carrier 10. The mounting carrier 10 has at least one cavity to accommodate components such as power supplies and electrical connection wires, protect the components accommodated therein, and provide mounting positions for these components.

[0071] like Figure 1 As shown, the mounting carrier 10 has opposing front end portion 110 and rear end portion 120, with the portion of the mounting carrier 10 adjacent to the rear end portion 120 forming the base 11 of the lighting device. The mounting carrier 10 also includes a clamping member 12 pivotally mounted to the base 11, allowing the lighting device to be easily clamped or hung on railings, ropes, or other objects. The clamping member 12 switches between a folded state and an unfolded state during rotation relative to the base 11. When the clamping member 12 is in the folded state, it is folded against the side wall of the mounting carrier 10; when the clamping member 12 is in the unfolded state, it is moved away from the side wall of the mounting carrier 10. Regardless of whether it is in the folded or unfolded state, a gap exists between the clamping member 12 and the side wall of the mounting carrier 10, allowing foreign objects to pass through. When folded, the gap between the clamping member 12 and the side wall of the mounting carrier 10 is small, allowing objects with small outer diameters to pass through. When unfolded, the gap between the clamping member 12 and the side wall of the mounting carrier 10 increases, allowing objects with larger outer diameters to pass through.

[0072] The mounting carrier 10 also includes a pivot shaft and a reset element connected between the base 11 and the clamping member 12. When the clamping member 12 is subjected to external force, it is moved away from the side wall of the mounting carrier 10. When the external force is removed, the clamping member 12 automatically moves closer to the side wall of the mounting carrier 10 to return to the folded state.

[0073] The power supply unit 20 includes at least one internal power supply and / or one electrical connection port 23 to power the light-emitting unit via the internal power supply, or to power the light-emitting unit via an external power supply connected to the electrical connection port 23. In one specific example of this application, the internal power supply includes a first power supply 21 implemented as a dry cell battery and a second power supply 22 implemented as a rechargeable battery, wherein the second power supply 22 is electrically connected to the electrical connection port 23. In other specific examples of this application, the lighting device may have different power supply configurations; for example, the internal power supply may only include dry cell batteries, or the internal power supply may only include rechargeable batteries, or it may not include an internal power supply.

[0074] When the lighting device includes two or more light-emitting units, each light-emitting unit can be equipped with a different power supply, or multiple light-emitting units can share the same power supply. That is, each power supply can be designed to supply power to multiple light-emitting units, or it can be designed to supply power only to a specific light-emitting unit corresponding to it.

[0075] The main body also includes a control unit electrically connected between the light-emitting unit and the power supply unit 20, used to control the electrical conduction of the light-emitting unit. The control mode can be adjusted by designing the electrical connection relationship between each light-emitting unit and the electrical connection relationship between each light-emitting unit and the control unit. For example, if each light-emitting unit is connected in series and in parallel to the same control switch, the electrical conduction of multiple light-emitting units can be controlled simultaneously by one control switch; or, if at least some light-emitting units are connected in parallel and respectively connected to different control switches, the electrical conduction of their corresponding light-emitting units can be independently controlled by multiple control switches.

[0076] In this embodiment, the lighting device includes at least one light-emitting unit electrically connected to the power supply unit 20. To prevent fluid from entering the light-emitting unit and affecting its normal function, a sealing device 40 is provided for the light-emitting unit in this application to improve the installation sealing of the light-emitting unit.

[0077] Specifically, in this embodiment, the sealing device 40 includes a frame body 41, at least one cover covering the light-emitting unit, and at least one sealing element sealingly disposed between the cover and the frame body 41. The sealing device 40 can prevent fluid from flowing from the outer shell 411 to the conductive components by blocking the passage between its outer shell 411 and the conductive components within the outer shell 411.

[0078] More specifically, the frame body 41 includes an outer shell 411 having a receiving cavity 401 and at least one mounting base for mounting a light-emitting unit. The outer shell 411 has a first cavity opening 4011, a first sidewall 4111, and mutually spaced second sidewalls 4112 and third sidewalls 4113 extending from a first side of the first sidewall 4111 and a second side opposite to the first side along the thickness direction set by the sealing device 40, respectively. The first sidewall 4111 is opposite to the first cavity opening 4011.

[0079] In this embodiment, the outer casing 411 further has a first hook-back portion 41141 and a second hook-back portion 41142 extending inwardly from the second sidewall 4112 and the third sidewall 4113 along the width direction set by the sealing device 40, respectively. The first hook-back portion 41141 and the second hook-back portion 41142 form the fourth sidewall 4114 of the outer casing 411 and define the first cavity opening 4011, defining the width dimension of the first cavity opening 4011. In a modified embodiment of this application, the second sidewall 4112 and the third sidewall 4113 define the first cavity opening 4011 and define the width dimension of the first cavity opening 4011, and the outer casing 411 does not form the first hook-back portion 41141 and the second hook-back portion 41142.

[0080] In this embodiment, the lighting device includes a first light-emitting unit 50, which includes a first light-emitting body 51 capable of emitting light when switched on. A first mounting base 412 is held within a receiving cavity 401 of the outer casing 411. The first mounting base 412 has a first mounting surface 4121, which includes a first conductive placement area 41201 suitable for arranging conductive components (e.g., the first light-emitting unit 50, electrical connection terminals). Figure 3 As shown, the first light-emitting body 51 of the first light-emitting unit 50 is mounted on the first conductive placement area 41201 of the first mounting surface 4121 to realize the electrical conduction of the first light-emitting body 51.

[0081] It is worth mentioning that, such as Figure 3 and Figure 4 As shown, the first light-emitting unit 50 also includes a lamp bowl 52 externally disposed on the first light-emitting body 51, which is used to converge the light emitted from the first light-emitting body 51.

[0082] The sealing device 40 includes a first cover 42 covering the first light-emitting unit 50. Specifically, the first cover 42 has a first cover opening 4201, a first cover side wall 421, a first cover second side wall 422 and a first cover third side wall 423 extending from a first side and a second side opposite to the first side of the first cover side wall 421 along the thickness direction set by the sealing device 40, respectively, and the first cover side wall 421 is opposite to the first cover opening 4201.

[0083] In this embodiment, the first cover 42 further has a first extension 4241 and a second extension 4242 extending outward from the second sidewall 422 and the third sidewall 423 of the first cover along the width direction set by the sealing device 40, respectively, and the first extension 4241 and the second extension 4242 form the four sidewalls 424 of the first cover. In a modified embodiment of this application, the first cover 42 does not have the first extension 4241 and the second extension 4242.

[0084] It is worth mentioning that, in some embodiments of this application, the first cover 42 is housed within the receiving cavity 401 of the outer shell 411, and the first mounting base 412 is mounted within the first cover 42. In this way, the first mounting base 412 is held within the receiving cavity 401 of the outer shell 411. In other embodiments of this application, the first mounting base 412 may be held within the receiving cavity 401 of the outer shell 411 in other ways, which is not limited to this application. For example, the first mounting base 412 may be fixed within the receiving cavity 401, or the first mounting base 412 may be mounted on the second cover 44 mentioned later, or the first mounting base 412 may be clamped between the first cover 42 and the second cover 44.

[0085] The first cover 42 is received upside down within the receiving cavity 401 of the outer shell 411 through the first cavity opening 4011. Specifically, both the first cavity opening 4011 and the first cover opening 4201 correspond to the first light-emitting unit 50, and the first cover 42 is mounted on the outer shell 411 with its first cover opening 4201 facing in the opposite direction to the first cavity opening 4011 of the outer shell 411. The width of the four side walls 424 of the first cover is greater than the width of the first cavity opening 4011, so that the first cover 42 engages within the receiving cavity 401 of the outer shell 411. Here, the orientation of the first cover opening 4201 refers to the direction from the portion of the first cover 42 opposite to the first cover opening 4201 (the side wall 421 of the first cover) towards the first cover opening 4201, and the orientation of the first cavity opening 4011 refers to the direction from the portion of the outer shell 411 opposite to the first cavity opening 4011 (the first side wall 4111) towards the first cavity opening 4011.

[0086] The first cover 42 has a first light-transmitting portion opposite to the first light-emitting body 51, so as to allow light emitted from the first light-emitting body 51 to pass through the first light-transmitting portion. The first light-transmitting portion of the first cover 42 is made of a light-transmitting material.

[0087] like Figure 5 As shown, the gap between the receiving cavity 401 of the outer shell 411 and the first cover 42, and the gap between the first cover 42 and the first mounting base 412, form a first fluid channel 4010 between the first cavity opening 4011 and the first mounting base 412. This may cause fluid to enter the first conductive placement area 41201 of the first mounting base 412 from the first cavity opening 4011, affecting the normal function of the first light-emitting body 51 arranged in the first conductive placement area 41201.

[0088] Preferably, the first cover 42 abuts against and fits tightly against the inner wall of the first cavity opening 4011 to prevent fluid from entering the receiving cavity 401 of the outer shell 411 from the first cavity opening 4011 and then into the first mounting base 412.

[0089] Furthermore, the sealing device 40 includes a first sealing member 43 sealingly disposed between the first cover 42 and the frame body 41. The first sealing member 43 is disposed in the first fluid channel 4010 and blocks the first cavity opening 4011 and the first light-emitting unit 50, thereby preventing fluid flowing from the first cavity opening 4011 into the first fluid channel 4010 from flowing to the first light-emitting unit 50. In this way, a first sealed cavity corresponding to the first light-emitting unit 50 is formed between the outer shell 411, the first cover 42, and the first sealing member 43, sealing the first light-emitting unit 50 within it.

[0090] The function of the first seal 43 is to block the fluid passage between the first cavity opening 4011 and the first light-emitting unit 50 of the first mounting base 412. The specific location of the first seal 43 is not limited to this application. In some embodiments of this application, the first seal 43 is sealed between the inner wall of the receiving cavity 401 of the first cover 42 and the outer shell 411, such as... Figure 5As shown. In one specific example of this application, the first sealing member 43 is disposed between the four side walls 424 of the first cover and the first side wall 4111 of the outer shell 411, and surrounds the opening 4201 of the first cover to prevent fluid from entering the light-emitting unit 50 from the opening 4201 of the first cover. In other specific examples of this application, the first sealing member 43 may be disposed between other side walls of the first cover 42 and other side walls of the outer shell 411, for example, between the second side wall 422 of the first cover and the second side wall 4112 of the outer shell 411, between the third side wall 423 of the first cover and the third side wall 4113 of the outer shell 411, or, for example, between the fourth side wall 424 of the first cover and the fourth side wall 4114 of the outer shell 411. In other specific examples of this application, the first sealing member 43 may surround the opening 4011 of the first cavity.

[0091] In other embodiments of this application, the first seal 43 seals between the first cover 42 and the first mounting base 412, such as... Figure 6 As shown. In a specific example of this application, the first seal 43 is disposed between the four side walls 424 of the first cover and the first mounting surface 4121 of the first mounting base 412, and surrounds the opening 4201 of the first cover.

[0092] In this embodiment, the first cover 42 has a first recessed groove, and the first sealing member 43 is fitted into the first recessed groove of the first cover 42. Preferably, the inner wall of the receiving cavity 401 of the outer shell 411 or the first mounting base 412 has a mounting groove corresponding to the first recessed groove of the first cover 42, and the first sealing member 43 is tightly fitted between the first recessed groove of the first cover 42 and the mounting groove of the outer shell 411 or the first mounting base 412.

[0093] In this embodiment of the application, the first sealing element 43 is integrally bonded to the first cover 42 by an overmolding process, so that the first sealing element 43 and the first cover 42 form an integral structure, that is, the first sealing element 43 and the first cover 42 are integrally formed to achieve a seamless connection between the first sealing element 43 and the first cover 42, thereby improving the sealing performance of the sealing device 40.

[0094] It is worth mentioning that, in this embodiment, the inner walls of the receiving cavities 401 of the first cover 42 and the outer shell 411 form at least one receiving cavity in the thickness direction set by the sealing device 40. The sealing device 40 further includes at least one pressing element 90 housed in the at least one receiving cavity. The pressing element 90 abuts against the first cover 42 and the outer shell 411 in the thickness direction set by the sealing device 40, so that the first cover 42 is pressed against the outer shell 411 of the frame body 41 or the first mounting base 412 in the thickness direction set by the sealing device 40, thereby reducing the gap between the first cover 42 and the frame body 41 and improving the sealing performance of the sealing device 40. That is, the sealing device 40 not only improves its sealing performance by blocking the passage between the outer shell 411 and the light-emitting body through the sealing element, but also further improves its sealing performance by pressing the cover covering the light-emitting body with the pressing element 90.

[0095] Specifically, the first extension portion 4241 and the second extension portion 4242 of the first cover 42 are respectively opposite to the first hook-back portion 41141 and the second hook-back portion 41142 of the outer shell 411. The gap between the first extension portion 4241 of the first cover 42 and the first hook-back portion 41141 of the outer shell 411 in the thickness direction set by the sealing device 40 forms a first receiving cavity 402; the gap between the second extension portion 4242 of the first cover 42 and the second hook-back portion 41142 of the outer shell 411 in the thickness direction set by the sealing device 40 forms a second receiving cavity 403. The sealing device 40 includes a first pressing element and a second pressing element respectively disposed between the first receiving cavity 402 and the second receiving cavity 403 between the outer shell 411 and the first cover 42.

[0096] In this embodiment, the main function of the clamping element 90 is to generate pressure on the first cover 42 in the thickness direction set by the sealing device 40, and its specific implementation is not limited to this application. The clamping element 90 can be implemented as, but is not limited to, screws, pins, springs, spring sheets, or rubber.

[0097] like Figure 1 and Figure 2As shown, a first retaining member 4142 is further provided between the outer shell 411 and the first cover 42 to fix the first cover 42 to the outer shell 411, maintain the relative positional relationship between the outer shell 411 and the first cover 42, and prevent the first cover 42 from moving relative to the outer shell 411. In a specific example of this application, the first retaining member 4142 is implemented as a screw, installed between the first cover's second side wall 422 and the second side wall 4112 of the outer shell 411, and between the first cover's third side wall 423 and the third side wall 4113 of the outer shell 411. Of course, the specific structure and retaining method of the first retaining member 4142 are not limited to this application.

[0098] In this embodiment, the lighting device further includes a second light-emitting unit 60, which includes a second light-emitting body 61 capable of emitting light when switched on. Specifically, the second light-emitting body 61 and the first light-emitting body 51 are mounted on the same mounting base, and the first light-emitting body 51 and the second light-emitting body 61 are opposite each other in the thickness direction set by the sealing device 40, so as to reduce the thickness occupied by the first reflective unit and the second light-emitting unit 60.

[0099] Accordingly, the first mounting base 412 has a second mounting surface 4122, which includes a second conductive placement area 41202 suitable for arranging conductive components (e.g., the second light-emitting unit 60, electrical connection terminals). Figure 4 As shown, the second light-emitting body 61 is installed in the second conductive placement area 41202 to achieve electrical conduction of the second light-emitting body 61.

[0100] The housing cavity 401 has a second cavity opening 4012 corresponding to the second light-emitting body 61, and the second cavity opening 4012 is opposite to the first cavity opening 4011. The sealing device 40 for the lighting device further includes a second cover 44 housed within the housing cavity 401 of the housing body 411 and covering the second light-emitting unit 60. The second cover 44 has a second cover opening 4401, a second cover side wall 441, second cover second side walls 442 and second cover third side walls 443 extending from the first and second sides of the second cover side wall 441 along the thickness direction set by the sealing device 40, respectively, and the second cover side wall 441 is opposite to the second cover opening 4401.

[0101] In this embodiment, the second cover 44 further has a third extension 4441 and a fourth extension 4442 extending outward from the second sidewall 442 and the third sidewall 443 of the second cover along the width direction set by the sealing device 40, respectively. The third extension 4441 and the fourth extension 4442 form the four sidewalls 444 of the second cover. In a modified embodiment of this application, the second cover 44 does not have the third extension 4441 and the fourth extension 4442.

[0102] It is worth mentioning that, in this embodiment, the first cover 42, the first light-emitting unit 50, and the second cover 44 correspond to each other in the thickness direction set by the sealing device 40. When the pressing element 90, which is in contact with the first cover 42, presses the first cover 42 against the frame body 41, the first light-emitting unit 50 and the second cover 44 are subjected to pressure in the same direction, and the second cover 44 is also pressed against the frame body 41. In this way, the pressure of the pressing element 90 can not only improve the sealing performance between the first cover 42 and the frame body 41, but also improve the sealing performance between the second cover 44 and the frame body 41.

[0103] The second cover 44 is received upside down within the receiving cavity 401 of the outer shell 411 through the second cavity opening 4012. Specifically, both the second cavity opening 4012 and the second cover opening 4401 correspond to the second light-emitting unit 60, and the second cover 44 is mounted on the outer shell 411 with the orientation of its second cover opening 4401 opposite to the orientation of the second cavity opening 4012. The width of the four side walls 444 of the second cover is greater than the width of the second cavity opening 4012, so that the second cover 44 is snapped into the receiving cavity 401 of the outer shell 411. Here, the orientation of the second cover opening 4401 refers to the direction from the part of the second cover 44 opposite to the second cover opening 4401 (the side wall 441 of the second cover) towards the second cover opening 4401, and the orientation of the second cavity opening 4012 refers to the direction from the part of the outer shell 411 opposite to the second cavity opening 4012 (the first cavity opening 4011) towards the second cavity opening 4012.

[0104] The second cover 44 has a second light-transmitting portion opposite to the second light-emitting body 61, allowing light emitted from the second light-emitting body 61 to pass through the second light-transmitting portion. The second light-transmitting portion of the second cover 44 is made of a light-transmitting material.

[0105] like Figure 5As shown, the gap between the receiving cavity 401 of the outer shell 411 and the second cover 44, and the gap between the second cover 44 and the first mounting base 412, form a second fluid channel 4020 between the second cavity opening 4012 and the first mounting base 412. This may cause fluid to enter the second conductive placement area 41202 of the first mounting base 412 from the second cavity opening 4012, affecting the normal function of the second light-emitting body 61 arranged in the second conductive placement area 41202.

[0106] Preferably, the second cover 44 abuts against the inner wall of the second cavity opening 4012 to prevent fluid from entering the receiving cavity 401 of the outer shell 411 from the second cavity opening 4012, and then into the first mounting base 412.

[0107] Further, the sealing device 40 includes a second sealing member 45 sealingly disposed between the second cover 44 and the frame body 41. The second sealing member 45 is disposed in the second fluid channel 4020 and blocks the flow between the second cavity opening 4012 and the second light-emitting unit 60, thereby preventing fluid flowing from the second cavity opening 4012 into the second fluid channel 4020 from flowing to the second light-emitting unit 60. Thus, a second sealed cavity corresponding to the second light-emitting unit 60 is formed between the outer shell 411, the second cover 44, and the second sealing member 45, sealing the second light-emitting unit 60 therein, wherein the first sealed cavity is opposite to the second sealed cavity.

[0108] The function of the second seal 45 is to block the fluid passage between the second cavity opening 4012 and the second light-emitting unit 60. The specific location of the second seal 45 is not limited by this application. In some embodiments of this application, the second seal 45 is sealed between the inner walls of the receiving cavity 401 of the second cover 44 and the outer shell 411. In a specific example of this application, the second seal 45 is disposed between the four side walls 444 of the second cover and the first side wall 4111 of the outer shell 411, and surrounds the second cavity opening 4012 to prevent fluid from entering the second light-emitting unit 60 from the second cavity opening 4012. In other specific examples of this application, the second seal 45 may be disposed between other side walls of the second cover 44 and other side walls of the outer shell 411, for example, between the second side wall 442 of the second cover and the second side wall 4112 of the outer shell 411, or between the third side wall 443 of the second cover and the third side wall 4113 of the outer shell 411.

[0109] In other embodiments of this application, the second seal 45 seals between the second cover 44 and the first mounting base 412. In a specific example of this application, the second seal 45 is disposed between the four side walls 444 of the second cover and the second mounting surface 4122 of the first mounting base 412, and surrounds the opening 4401 of the second cover.

[0110] In this embodiment, the second cover 44 has a second recessed groove, and the second sealing member 45 is fitted into the second recessed groove of the second cover 44. The inner wall of the receiving cavity 401 of the outer shell 411 or the first mounting base 412 has a first mounting groove 404 corresponding to the second recessed groove of the second cover 44, and the second sealing member 45 is tightly fitted between the second recessed groove of the second cover 44 and the first mounting groove 404 of the outer shell 411 or the first mounting base 412.

[0111] In this embodiment, the second sealing element 45 is integrally bonded to the second cover 44 through an overmolding process, so that the second sealing element 45 and the second cover 44 form an integral structure. That is, the second sealing element 45 and the second cover 44 are integrally formed to achieve a seamless connection between the second sealing element 45 and the second cover 44, thereby improving the sealing performance of the sealing device 40.

[0112] It is worth mentioning that the solution in this application not only achieves side sealing through the first sealing element 43 and the second sealing element 45 to prevent fluid from entering the sealing device 40 from the side (e.g., Figure 11 As shown), end sealing is also achieved through other sealing components to prevent fluid from entering the sealing device 40 from its end (e.g., Figure 12 (As shown). That is, the sealing device 40 not only seals through side sealing but also through end sealing to achieve multi-directional sealing and improve the sealing performance of the sealing device 40.

[0113] Specifically, the first cover 42 has a first end 4202 and a second end 4203 opposite to each other, and the lighting device further includes a sealing assembly disposed at the first end 4202 of the first cover 42 to achieve sealing of the first end of the sealing device 40.

[0114] More specifically, the sealing assembly disposed at the first end 4202 of the first cover 42 includes a second mounting base 46 disposed at the first end 4202 of the first cover 42. The first end 4202 of the first cover 42 has a first end groove 4204, and the outer periphery of a portion of the second mounting base 46 (i.e., the base body 461) is in close contact with the inner wall of the first end groove 4204 to improve the sealing between the second mounting base 46 and the first cover 42.

[0115] In the embodiments of this application, the second mounting base 46 is integrally formed onto the first cover 42 by a molding process to improve the sealing between the second mounting base 46 and the first cover 42.

[0116] The second mounting base 46 further includes a shielding portion 462 extending laterally outward from the base body 461 (e.g., Figures 7 to 9 As shown), to block the light emitted from the first light-emitting body 51 and the second light-emitting body 61 of the lighting device to the first end 4202 of the first cover 42, that is, to prevent the side lamp (the first light-emitting body 51 and the second light-emitting body 61) from leaking light.

[0117] The second mounting base 46 further includes at least one protrusion 463 protruding from its outer surface (e.g., Figure 9 As shown, the inner wall of the receiving cavity 401 of the outer shell 411 has a limiting groove 405 corresponding to the at least one protrusion 463. The protrusion 463 is limited in the limiting groove 405 to prevent the first cover 42 from moving during assembly. For example, to prevent the first cover 42 from moving up and down during the installation of the clamping element 90.

[0118] In particular, each light-emitting unit generates heat during the light-emitting process, and the second mounting base 46 includes at least one heat dissipation part, which is made of a material with a high thermal conductivity to dissipate heat.

[0119] In this embodiment, the lighting device further includes a third light-emitting unit 70, the third light-emitting unit 70 including a mounting plate and a third light-emitting body 71 capable of emitting light mounted on the mounting plate, such as... Figure 10 As shown. The second mounting base 46 has a third mounting surface, which includes a third conductive placement area suitable for arranging conductive components (e.g., the third light-emitting unit 70, electrical connection terminals). The third light-emitting unit 70 is arranged in the third conductive placement area of ​​the third mounting surface of the second mounting base 46 such that the mounting plate is mounted on the third conductive placement area of ​​the third mounting surface of the second mounting base 46.

[0120] The second mounting base 46 has a first through hole 464 for allowing electrical connection wires to pass through (e.g., Figure 8 As shown, the electrical connection wire connected to the electrical connection portion of the first end 4202 of the first cover 42, which is adjacent to the first mounting base 412, can pass through the first wire hole 464 and connect to the electrical connection portion of the mounting plate of the third light-emitting unit 70, thereby realizing electrical conduction between the first light-emitting unit 50, the second light-emitting unit 60 and the third light-emitting unit 70.

[0121] The sealing assembly disposed at the first end 4202 of the first cover 42 in the sealing device 40 further includes a cover 49 covering the third light-emitting unit 70. The cover 49 includes a cover body 491 and a tongue portion 493 extending laterally from the cover body 491. The tongue portion 493 is inserted between the outer shell 411 and the first cover 42, so that the cover 49 is fastened between the outer shell 411 and the first cover 42. Preferably, the first cover 42 and the outer shell 411 are tightly fitted to the tongue portion 493 to improve the sealing performance between the cover 49 and the first cover 42 and the outer shell 411.

[0122] The cover 49 also includes a third light-transmitting portion opposite to the third light-emitting body 71, allowing light emitted by the third light-emitting body to pass through the third light-transmitting portion. The third light-transmitting portion is implemented as a lens 492 and is detachably mounted to the cover body 491.

[0123] The cover 49 and the first cover 42 are fixed together by a second retaining member 4249 to maintain their relative position. The second retaining member 4249 is implemented as a screw; the first cover 42 has a threaded post that mates with the screw, and the cover 49 has a through hole that mates with the screw. The cover 49 is fixed to the first cover 42 by the screw. Of course, the specific structure and retaining method of the second retaining member 4249 are not limited to this application.

[0124] The gap between the cover 49 and the second mounting base 46 creates a third fluid channel between them, which may cause fluid to enter the third conductive placement area of ​​the second mounting base 46 from the cover 49, affecting the normal function of the third light-emitting body 71 disposed in the third conductive placement area.

[0125] Furthermore, the sealing assembly disposed at the first end 4202 of the first cover 42 in the sealing device 40 further includes a third sealing member 47 which is sealed in the third fluid channel and blocks the third light-emitting unit 70 between the cover 49 and the second mounting base 46, so as to prevent fluid flowing from the cover 49 into the third fluid channel from flowing to the third light-emitting unit 70.

[0126] The function of the third seal 47 is to block the fluid passage between the cover 49 and the third light-emitting unit 70 of the second mounting base 46. The specific location of the third seal 47 is not limited to this application. In a specific example of this application, the third seal 47 surrounds the third light-emitting unit 70, and the outer periphery of the third seal 47 is tightly fitted to the inner wall of the tongue portion 493 of the cover 49 to prevent fluid from flowing from the cover 49 to the third light-emitting unit 70 of the second mounting base 46.

[0127] The lighting device further includes a sealing assembly disposed at the second end 4203 of the first cover 42 to seal the second end of the sealing device 40. The sealing assembly disposed at the second end 4203 of the first cover 42 includes a fourth sealing member 48 disposed at the second end 4203 of the first cover 42. Specifically, the second end 4203 of the first cover 42 has a second end groove 4205, and the outer periphery of the fourth sealing member 48 is tightly fitted to the inner wall of the second end groove 4205 to prevent fluid from flowing into the first cover 42 from the gap between the fourth sealing member 48 and the inner wall of the second end groove 4205.

[0128] The fourth seal 48 has a second wire hole 481 for allowing electrical connection wires to pass through. The electrical connection wire connected to the electrical connection portion of the first mounting base 412 adjacent to the second end 4203 of the first cover 42 can pass through the second wire hole 481 and connect to the circuit board of the power supply unit 20 to realize electrical conduction between the first light-emitting unit 50, the second light-emitting unit 60 and the third light-emitting unit 70 and the power supply unit 20.

[0129] It is worth mentioning that, in the embodiments of this application, the first seal 43, the second seal 45, the third seal 47, and the fourth seal 48 are all made of elastic material, so that each seal can fit tightly with the component it contacts during the compression process, thereby improving the sealing performance. In some embodiments of this application, the first seal 43, the second seal 45, the third seal 47, and the fourth seal 48 are made of soft rubber, for example, tetraphenylethylene (TPE).

[0130] The sealing assembly disposed at the second end 4203 of the first cover 42 further includes a connecting portion 80 installed on the outer shell 411. The connecting portion 80 is adjacent to the second end 4203 of the first cover 42 and includes a connecting cavity 81 covering the outer shell 411. The connecting cavity 81 not only covers the portion of the outer shell 411 adjacent to the second end 4203 of the first cover 42, but also covers the second end 4203 of the first cover 42 and the fourth sealing member 48 installed at the second end 4203.

[0131] Preferably, the outer periphery of the outer shell 411 and the outer periphery of the first cover 42 are tightly fitted to the inner wall of the connecting cavity 81 to improve the sealing between the outer shell 411 and the first cover 42 and the connecting part 80, preventing fluid from flowing from the second end 4203 of the first cover 42 to the conductive placement area of ​​the first mounting base 412 and the second mounting base 46, thus affecting the normal operation of each light-emitting unit arranged in the conductive placement area of ​​the first mounting base 412 and the second mounting base 46.

[0132] The connecting portion 80 not only serves as part of a sealing assembly to prevent fluid from flowing into the first cover 42, but also connects the sealing device 40 to the mounting carrier 10. The connecting portion 80 also includes a connecting arm 82 connecting the connecting cavity 81 and the mounting carrier 10.

[0133] The sealing device 40 can be fixed to the mounting carrier 10 or movably mounted to the mounting carrier 10, which is not limited to this application. In a specific example of this application, the sealing device 40 is pivotally connected to the mounting carrier 10 via the connecting portion 80. Accordingly, in this specific example, the connecting portion 80 further includes a connecting shaft 83 disposed between the connecting arm 82 and the mounting carrier 10, so that the sealing device 40 can rotate relative to the mounting carrier 10.

[0134] In summary, the lighting device based on the embodiments of this application is explained, wherein the sealing device 40 can prevent fluid from flowing from the housing 411 to the conductive component by blocking the passage between its housing 411 and the conductive component within the housing 411. Furthermore, the sealing device 40 achieves sealing not only through side sealing but also through end sealing, thereby achieving multi-directional sealing and improving the sealing performance of the sealing device 40.
