[0049] In the embodiment, a part of the heat conduction module is attached to the wall surface of the lamp body 1 to increase the contact area between the heat conduction module and the lamp body 1. The greater the contact area between the heat conduction module and the lamp body 1, the higher the heat exchange efficiency between the heat conduction module and the lamp body 1, thereby helping to improve the heat exchange speed between the outer surface of the lamp body 1 and the air, and effectively improving the heat dissipation effect of the lamp structure in use.

[0050] With reference to Figures 2-4 In the embodiment, the heat conduction module includes a heat conduction cup 31, which includes a bottom plate 311 and a heat conduction ring 312 surrounding the periphery of the bottom plate 311. The bottom plate 311 is attached to the side of the lamp plate 11 away from the lampshade 2, and the heat conduction ring 312 abuts against the inner wall of the lamp body 1 and extends away from the bottom plate 311 along the inner wall of the lamp body 1. The heat generated by the lamp plate 11 is transmitted to the inner wall of the lamp body 1 in turn through the bottom plate 311 and the heat conduction ring 312. Since the heat conduction ring 312 abuts against the inner wall of the lamp body 1 and the contact area between the heat conduction ring 312 and the inner wall of the lamp body 1 is greater than that between the bottom plate 311 and the inner wall of the lamp body 1, the heat transmitted by the bottom plate 311 can be quickly conducted to the inner wall of the lamp body 1 through the heat conduction ring 312, and finally heat exchanged through the convection between the outer surface of the lamp body 1 and the air to complete the heat dissipation of the lamp structure.

[0051] In the embodiment, the heat conduction ring 312 is arranged on one side of the bottom plate 311, and extends towards the side close to the lampshade 2 along the inner wall of the lamp body 1, and the longitudinal section of the heat conduction cup 31 is in a "U" shape. In this way, the heat dissipation of the lamp plate 1 in multiple directions can be realized through the heat exchange between the bottom plate 311 and the lamp plate 1 and the heat exchange between the heat conduction ring 312 and the side wall of the lamp plate 1. Of course, in other embodiments, the heat conduction ring 312 can also be arranged on both sides of the bottom plate 311, and the longitudinal section of the heat conduction cup 31 is in an "H" shape, which can also achieve the purpose of increasing the contact area between the heat conduction cup 31 and the inner wall of the lamp body 1.

[0052] Preferably, in the embodiment, the heat conduction cup 31 is made of a heat conduction material, preferably aluminum. This can improve the rapid conduction of the heat conduction cup 31 to the heat generated by the lamp plate 11.

[0053] Optionally, the lamp body 1 is made of aluminum or plastic, which has lower weight, higher strength and better wear resistance, which helps to achieve the lightweight goal of the lamp structure and prolong the service life of the lamp structure.

The diameter of the light reflecting cup 12 gradually increases in the direction away from the lamp panel 11. The light reflecting cup 12 is used for reflecting the light emitted by the light source on the lamp panel 11, so as to control the direction and angle of the light, thereby enhancing the lighting effect.

[0055] Optionally, as shown in Figure 2 and Figure 3 , the lamp shade 2 comprises an upper cover 21 and a shade body 22. The shade body 22 is made of transparent material, such as glass, transparent acrylic, etc. The shade body 22 is arranged on the light reflecting cup 12 to facilitate the light to pass through. The upper cover 21 is arranged on the side of the shade body 22 away from the light reflecting cup 12, and is sealingly connected with the lamp body 1, so as to ensure the sealing property of the lamp structure, prevent external water vapor from entering the inside of the lamp structure, and affect the service life of the lamp panel 11.

[0056] Optionally, referring to Figure 1 and Figure 2 , the mounting seat 4 comprises a mounting bracket 41. The outer side of the lamp body 1 is provided with a connecting portion, which is rotatably connected to the mounting bracket 41, so as to adjust the relative angle between the lamp body 1 and the mounting bracket 41, and further realize the adjustment of the irradiation angle of the lamp structure.

[0057] Further, the mounting seat 4 further comprises a ground plug 42. The mounting bracket 41 is fixedly connected with the ground plug 42, and through the ground plug 42, the positioning and fixing of the lamp structure on the ground can be realized.

[0058] Embodiment Two

[0059] The lamp structure provided by the present embodiment is basically the same as the lamp structure provided by the first embodiment, and the difference between the present embodiment and the first embodiment lies in the different arrangement position and structure of the heat conduction module.

[0060] As shown in Figures 5-7 , in the present embodiment, the heat conduction module comprises a heat conduction platform 32, which is arranged in the inner cavity of the lamp body 1 and is in heat conduction connection with the inner wall of the lamp body 1. One side of the heat conduction platform 32 facing the lamp shade 2 is a mounting surface 321, and the lamp panel 11 is mounted on the mounting surface 321. The heat emitted by the lamp panel 11 can be conducted to the lamp body 1 through the heat conduction platform 32, and heat exchange is realized through the convection between the outer surface of the lamp body 1 and the air.

[0061] Specifically, in the present embodiment, part of the bottom wall of the lamp body 1 is recessed towards the inner cavity of the lamp body 1 to form the heat conduction platform 32. That is to say, the heat conduction platform 32 and the lamp body 1 are an integral molding structure, and the heat conduction platform 32 and the lamp body 1 are made of the same material, and the heat conduction speed and efficiency are also the same, which helps to ensure the balance of heat transfer.

[0062] Further, the lamp body 1 is made of a heat-conducting material, preferably aluminum.

[0063] More specifically, the side of the bottom wall facing the lamp panel 11 is the mounting surface 321, and mounting holes 322 are formed in the mounting surface 321 to form mounting positions. Corresponding through holes are formed in the lamp panel 11, fasteners are inserted through the through holes and screwed into the mounting holes 322, thereby achieving reliable connection between the lamp panel 11 and the lamp body 1.

[0064] More specifically, the heat-conducting module further includes heat dissipation fins 33. The side of the bottom wall away from the lamp panel 11 is provided with a plurality of heat dissipation fins 33, which are arranged in parallel and at intervals, and extend away from the lamp body 1. The heat generated by the lamp panel 11 is directly convected with air through the outer surface of the lamp body 1 and the heat dissipation fins 33, thereby achieving heat dissipation.

[0065] Preferably, the thickness of the heat dissipation fins 33 gradually decreases in the direction away from the lamp body 1. This improves the air flow speed and further improves the heat dissipation efficiency.

[0066] Embodiment Three

[0067] This embodiment provides a lamp structure which is basically the same as the lamp structure provided in Embodiment Two. The difference between this embodiment and Embodiment Two lies in the specific structure of the heat-conducting module.

[0068] As shown in Figure 8 and Figure 9 In this embodiment, the heat-conducting module further includes a heat-conducting rib 34, one end of which is connected to the lamp panel 11, and the other end of which is connected to the mounting surface 321 or the inner wall of the lamp body 1. The heat generated by the lamp panel 11 can be transmitted to the heat-conducting platform 32 or the lamp body 1 through the heat-conducting rib 34, and finally exchanged through the convection between the outer surface of the lamp body 1 and the air.

[0069] Specifically, the top surface of the heat-conducting rib 34 is provided with mounting holes 322, thereby forming the above-mentioned mounting positions. Corresponding through holes are formed in the lamp panel 11, fasteners are inserted through the through holes and screwed into the mounting holes 322, thereby achieving reliable connection between the lamp panel 11 and the heat-conducting rib 34, i.e. completing the positioning and fixing of the lamp panel 11. The heat-conducting rib 34 can not only support and fix the installation of the lamp panel 11, but also act as a medium for heat conduction, thereby achieving the transmission and transfer of heat of the lamp panel 11.

[0070] More specifically, multiple heat-conducting ribs 34 are provided, arranged in an array structure, with the geometric center of the array structure collinear with the geometric center of the lamp plate 11. It can be understood that if the lamp body 1 is a hollow cylindrical structure and the lamp plate 11 is a circular plate, then the multiple heat-conducting ribs 34 are arranged in a circular array, with the center of the circular array collinear with the center of the lamp plate 11 and the central axis of the lamp body 1. If the lamp body 1 is a hollow cuboid structure and the lamp plate 11 is a rectangular plate, then the multiple heat-conducting ribs 34 are arranged in a rectangular array, with the center of the rectangular array collinear with the center of the lamp plate 11 and the center of the lamp body 1. The specific arrangement of the heat-conducting ribs 34 can be designed according to actual needs and is not limited here.

[0071] More specifically, the lamp body 1, the heat-conducting rib 34, and the heat-conducting platform 32 are integrally molded, which is convenient for processing and manufacturing and also helps to ensure stable heat transfer.

[0072] Preferably, the lamp body 1, the heat-conducting rib 34, and the heat-conducting platform 32 are all made of heat-conducting materials, preferably aluminum.

[0073] Of course, in other embodiments, only the heat-conducting rib 34 can be provided, without the heat-conducting platform 32 and the heat sink 33. One end of the heat-conducting rib 34 is connected to the lamp plate 11, and the other end is connected to the bottom wall of the lamp body 1. This can also achieve reliable installation of the lamp plate 11 and heat transfer of the lamp plate 11, and help reduce the overall weight of the lamp body 1.

[0074] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
