Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model. Additionally, in the present utility model, the descriptions involving "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0028] In view of the technical defects existing in the related art, the present utility model provides a lamp that is easy to dissipate heat. Please refer to Figures 1 to 3 , the lamp includes a plurality of first LED lamp boards 100, a heat conducting member 200, a heat dissipation base 300, and a lamp socket head 400. The first LED lamp boards 100 are connected to each other and enclose a long cylindrical structure. The lamp beads of each first LED lamp board 100 are located on the outer peripheral side of the long cylindrical structure, that is, the first LED lamp boards 100 are arranged in a long strip shape. A plurality of lamp beads are arranged at intervals along the length direction of each first LED lamp board 100. It should be noted that in some embodiments, the first LED lamp boards 100 enclose a polygonal long cylindrical structure, and the outer peripheral wall of the heat conducting member 200 is in clearance fit with the inner peripheral wall of the polygonal long cylindrical structure formed by enclosing the first LED lamp boards 100. That is, the long cylindrical structure formed by enclosing the first LED lamp boards 100 can be a square long cylindrical shape, a pentagonal long cylindrical shape, or other polygonal long cylindrical shapes, and no specific limitation is made here.

[0029] The heat conducting member 200 is arranged in a long strip shape and is inserted into the long cylindrical shape formed by enclosing the first LED lamp boards 100; thus, the heat generated when each first LED lamp board 100 works can be conducted to the heat conducting member 200. The heat conducting member 200 is made of a metal material, such as copper alloy, aluminum alloy, or other metal materials with good heat conducting performance.

[0030] Further, one end of the heat dissipation base 300 is connected to the heat conducting member 200. The connection manner between the heat dissipation base 300 and the heat conducting member 200 can be a plug-in connection, a snap connection, or a screw locking connection, etc., and no specific limitation is made here. A plurality of heat dissipation rib strips 310 are arranged at intervals along the circumferential direction of the outer peripheral wall of the heat dissipation base 300, and each heat dissipation rib strip 310 extends along the length direction of the heat conducting member 200; thus, the heat on the heat conducting member 200 can be conducted to the heat dissipation base 300. A plurality of heat dissipation rib strips 310 are arranged on the heat dissipation base 300, and the plurality of heat dissipation rib strips 310 can increase the contact surface between the heat dissipation base 300 and the external environment, so that the heat on the heat dissipation base 300 can be quickly exchanged with the external environment, improving the heat dissipation efficiency. Similarly, the material used for the heat dissipation base 300 is also made of a metal material with good heat conducting performance, such as copper alloy or aluminum alloy, so that it can conduct and dissipate heat better.

[0031] In addition, the lamp socket head 400 is connected to the end of the heat dissipation base 300 far from the heat conducting member 200, and a power connection end 420 for connecting to an external power supply is arranged at the end of the lamp socket head 400 far from the heat dissipation base 300. Through the power connection end 420, an electrical connection is made with the external power supply, so that the first LED lamp board 100 can be powered on and emit light.

[0032] Through the above technical solution, a heat conducting member 200 is provided on the back side of the lamp beads of multiple first LED lamp boards 100 of the lamp. The heat conducting member 200 conducts the heat of the first LED lamp board 100 and transfers the heat to the heat dissipation base 300. Multiple heat dissipation ribs 310 are provided on the heat dissipation base 300 to increase the heat dissipation area of the heat dissipation base 300. With such a setting, the heat generated when multiple first LED lamp boards 100 work can be transferred to the heat dissipation ribs 310 on the heat dissipation base 300 for dissipation, accelerating the heat exchange between the first LED lamp board 100 and the external environment, thereby avoiding the phenomenon that the first LED lamp board 100 fails due to overheating during long-term operation of the lamp, and thus extending the service life of the lamp.

[0033] Please refer to Figures 2 to 4 , in order to facilitate the connection between the heat dissipation base 300 and the heat conducting member 200 and reduce the weight of the heat dissipation base 300, in this embodiment, the heat dissipation base 300 is arranged in a cylindrical structure.

One end of each screw 900 passes through the through hole 411 and the through hole 321 and is threadedly connected to the threaded hole 210. In this way, under the locking of each screw 900, the heat dissipation base 300 can be clamped between the lamp socket head 400 and the heat conducting member 200, realizing the connection between the heat dissipation base 300 and the lamp socket head 400 and the heat conducting member 200.

[0035] In order to further increase the contact area between the heat dissipation base 300 and the external environment, in some embodiments, one end of each heat dissipation rib 310 is located at one port of the heat dissipation base 300, and the other end of each heat dissipation rib 310 extends in a curve around the other port of the heat dissipation base 300. Through the direction of the curve winding, the length of the heat dissipation rib 310 can be increased, thereby increasing the contact surface between the heat dissipation rib 310 and the external environment, and thus accelerating the heat dissipation and improving the heat dissipation efficiency.

[0036] For the convenience of the connecting wire of the first LED lamp panel 100 to pass through the heat dissipation base 300 to the power connection end 420 of the lamp socket head 400 for power connection, in some embodiments, the connecting plate 320 is provided with a first wire passing hole 322 penetratingly, and a second wire passing hole 412 is provided at the bottom of the installation groove 410 corresponding to the first wire passing hole 322.
