Figure 1As shown, the enhanced heat-conducting center hole lamp comprises: an upper cover 500, a sealing cover 400, a mounting portion 300 and a shell 100; the shell 100 is provided with a cavity with an opening at one end, the sealing cover 400 matches the open end of the shell 100, the sealing cover 400 and the shell 100 are detachably connected, and the upper cover 500 is buckled on the open end of the shell 100; a yielding portion 200 is provided at the bottom of the shell 100, the yielding portion 200 probes into the cavity of the shell 100, and the yielding portion 200 is suitable for making way for the fountain nozzle; the yielding portion 200 is provided with a first water outlet 220, the sealing cover 400 is provided with a second water outlet 440 opposite to the first water outlet 220, and the upper cover 500 is provided with a third water outlet 540 opposite to the second water outlet 440; the first water outlet 220, the second water outlet 440 and The third water outlet 540 is suitable for spraying water columns; the mounting portion 300 includes: a mounting plate 310, a first heat dissipation layer 320 and a second heat dissipation layer 330; the mounting plate 310 is arranged between the inner side wall of the shell 100 and the yield portion 200, and the mounting plate 310 is suitable for installing a lighting device, and the lighting end of the lighting device faces the opening side of the shell 100; the first heat dissipation layer 320 and the second heat dissipation layer 330 are arranged on the same side of the mounting plate 310, the first heat dissipation layer 320 is close to the inner side wall of the shell 100, and the second heat dissipation layer 330 is close to the yield portion 200; the sealing cover 400 is provided with a first light-transmitting portion 410, and the first light-transmitting portion 410 is arranged opposite to the lighting end of the lighting device; the upper cover 500 is provided with a second light-transmitting portion 520, and the second light-transmitting portion 520 is arranged opposite to the first light-transmitting portion 410.

[0038] Here, it should be noted that the interior of the cavity of the shell 100 is suitable for providing a placement space for the lighting device, and the sealing cover 400 is suitable for sealing the lighting device inside the shell 100 to prevent water from flowing into the shell 100 and damaging the lighting device; the upper cover 500 is buckled on the opening end of the shell and the sealing cover at the same time, and is suitable for further sealing and protecting the cavity of the shell 100. The yielding part 200 of the shell 100 is suitable for making way for the fountain nozzle at the bottom of the shell 100. The fountain nozzle can be embedded in the yielding groove 240 of the yielding part 200 (the cavity formed between the outer wall of the bottom of the shell 100 and the yielding part 200), and the first water outlet 220 of the yielding part 200 is arranged opposite to the fountain nozzle, and the first water outlet 220, the second water outlet 440, and the third water outlet 540 are arranged opposite to each other. The barrier-free arrangement can ensure that the fountain nozzle can smoothly spray water columns to the outside. The mounting plate 310 of the mounting portion 300 is disposed inside the cavity of the housing 100 and is suitable for mounting and supporting the lighting device to ensure the placement stability of the lighting device. The mounting plate 310 is connected to the first heat dissipation layer 320 and the second heat dissipation layer 330, and the heat generated by the lighting device can be transferred from the mounting plate 310 to the first heat dissipation layer 320 and the second heat dissipation layer 330. Since the first heat dissipation layer 320 is closely attached to the inner wall of the housing 100, the heat can be efficiently transferred from the first heat dissipation layer 320 to the housing 100. The shell 100 directly transfers the heat outward to achieve a first-order heat dissipation effect. Since the second heat dissipation layer 330 is tightly fitted with the give-way portion 200, the heat can be efficiently transferred from the second heat dissipation layer 330 to the give-way portion 200. The give-way portion 200 directly transfers the heat outward, and since there is a water column sprayed from the fountain nozzle in the give-way groove 240 of the give-way portion 200 (a cavity formed between the outer wall of the bottom of the shell 100 and the give-way portion 200), the heat of the give-way portion 200 can be quickly taken away by the water flow, thereby achieving a second-order heat dissipation effect. The overall structure of the present application is compact and the installation process is simple. While ensuring the smooth operation of the fountain, the lighting device can work normally. At the same time, the first heat dissipation layer 320 and the second heat dissipation layer 330 effectively increase the heat dissipation area, realize efficient heat conduction, and can quickly transfer the heat generated by the lighting device to the outside, thereby reducing the temperature inside the shell 100 and further improving the working stability of the lighting device.

[0039] In a possible implementation, the clearance portion 200 is disposed in the middle of the housing 100. It should be noted that the fountain nozzle is disposed in the middle of the bottom of the housing 100, and the lighting device is arranged outside the clearance portion 200, which can effectively improve the viewing experience, and at the same time is beneficial to the overall heat dissipation and facilitates the overall disassembly and maintenance.

[0040] Furthermore, the main body of the mounting plate 310 is an annular structure, the inner ring of the annular structure of the mounting plate 310 matches the clearance portion 200, and the mounting plate 310 is sleeved with the clearance portion 200; the outer ring of the annular structure of the mounting plate 310 matches the inner side of the housing 100, and the housing 100 is sleeved with the mounting plate 310. Figure 2 and Figure 7 As shown, the inner diameter of the mounting plate 310 is slightly larger than the diameter of the easing portion 200 to ensure that the mounting plate 310 can be mounted on the easing portion 200, and the outer diameter of the mounting plate 310 is slightly smaller than the inner diameter of the shell 100 to ensure that the mounting plate 310 can be set between the easing portion 200 and the shell 100. It should be noted that setting the mounting plate 310 in an annular structure can effectively increase the area of ​​the mounting plate 310.

[0041] It should be noted that the mounting plate 310 is suitable for placing the lighting device, and the lighting end of the lighting device faces the sealing cover 400. Further, the lighting device can be an LED bulb or an LED light strip. Further, the lighting device uses more than two LED bulbs 600; Fig.12 As shown, six LED bulbs 600 are arranged around the mounting ring 610 along the annular structure of the mounting ring 610; the mounting ring 610 is then placed on the mounting plate 310 of the mounting portion 300, and the inner and outer rings of the mounting ring 610 preferably contact the first heat dissipation layer 320 and the second heat dissipation layer 330. The present application does not limit the installation method of the lighting device, and the mounting ring 610 can be fixed in a fixed mode, or the LED bulbs or LED light strips can be directly placed on the mounting plate 310.

[0042] Furthermore, the mounting plate 310 is provided with a wire hole 360 ​​, and the wire hole 360 ​​is suitable for passing the wires of the lighting device.

[0044] Furthermore, the first heat dissipation layer 320 of the mounting portion 300, the second heat dissipation layer 330 and the mounting plate 310 are integrally formed, or the three are fixed as a whole by welding. Fig.11 As shown, the cross section of the mounting portion 300 is a double "U" shaped structure. Furthermore, the first heat dissipation layer 320, the second heat dissipation layer 330 and the mounting plate 310 are all made of aluminum or copper or other materials with good heat dissipation. The optimal thickness of the first heat dissipation layer 320, the second heat dissipation layer 330 and the mounting plate 310 is 1-5MM.

[0045] Furthermore, the main body of the housing 100 and the main body of the clearance portion 200 are both cylindrical structures, the main body of the mounting plate 310 is a circular plate structure; the main bodies of the first heat dissipation layer 320 and the second heat dissipation layer 330 are both circular tubular structures. It should be noted that the positional relationship between the housing 100, the clearance portion 200, the first heat dissipation layer 320 and the second heat dissipation layer 330 is as described above, and setting each component in a circular shape can reduce the difficulty of processing, reduce the processing cost, and improve the overall aesthetics.

[0049] In a possible implementation, the mounting portion 300 is provided with a fixing portion 340, and the fixing portion 340 is disposed on a side where the first heat dissipation layer 320 is connected to the housing 100, and the mounting portion 300 is connected to the placement portion 110 via the fixing portion 340. Figure 2 and Figure 7As shown, the main body of the fixing portion 340 is also an annular structure, which is sleeved on the outside of the mounting portion 300. The fixing portion 340 matches the placement portion 110. The fixing portion 340 can be placed on the placement portion 110 to achieve the connection between the mounting portion 300 and the shell 100. It should be noted that in order to ensure the connection stability between the mounting portion 300 and the shell 100, the fixing portion 340 and the placement portion 110 can be fixedly connected by welding or bonding.

The other end of the sealing ring 230 passes through the second water outlet 440 and is arranged close to the inner wall of the second water outlet 440. Under the action of the sealing ring 230, the gap between the sealing cover 400 and the yielding portion 200 can be effectively sealed to prevent water from flowing into the interior of the shell 100 from between the sealing cover 400 and the yielding portion 200.
