[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0042] As Figures 1 to 4As shown in the figure, the ground-inserted lamp 100 provided by an embodiment of the present application includes a lamp main body 10 and a ground-inserted rod 20. The lamp main body 10 includes a lamp housing 11, a circuit board 12, and a heat dissipation body 13. The circuit board 12 is fixedly installed in the lamp housing 11. The circuit board 12 is integrated with lamp beads 121, and the light generated by the lamp beads 121 can pass through the lamp housing 11 and be emitted outward. The heat dissipation body 13 is attached to the side surface 122 of the circuit board 12 facing away from the lamp beads 121 and is connected to the circuit board 12; the ground-inserted rod 20 is connected to the lamp housing 11 and is used to carry the lamp main body 10. That is to say, the heat dissipation body 13 can directly dissipate the heat generated when the circuit board 12 works, so as to achieve efficient heat dissipation of the circuit board 12. Here, a heat dissipation part (not shown in the figure) can be integrated on the lamp housing 11, and the heat dissipation body 13 is thermally connected to the heat dissipation part, so that the heat conducted by the heat dissipation body 13 to the circuit board 12 can be dissipated to the outside air through the heat dissipation part on the lamp housing 11, and finally the purpose of dissipating heat from the circuit board 12 is achieved. Of course, in other embodiments, the entire lamp housing 11 can also be used as a heat dissipation component.

[0043] It can be understood that since the heat dissipation body 13 of the present application is directly attached to the side surface 122 of the circuit board 12 facing away from the lamp beads 121, direct contact between the heat dissipation body 13 and the circuit board 12 can be achieved, and there can be a sufficient contact surface between the heat dissipation body 13 and the circuit board 12. When the ground-inserted lamp 100 works, the heat dissipation body 13 can timely export the heat generated after the lamp beads 121 on the circuit board 12 emit light, so as to achieve efficient heat dissipation of the circuit board 12 and meet the use requirements of heat dissipation of the circuit board 12.

[0044] As Figure 3 shown, the lamp housing 11 includes a lamp housing base 111 and a lamp housing upper cover 112 that are connected to each other. The circuit board 12 is fixedly connected to the lamp housing upper cover 112, and the lamp housing base 111 is rotatably connected to the ground-inserted rod 20. Here, the circuit board 12 can be connected to the lamp housing upper cover 112 in a threaded manner through two screws 101 passing through the circuit board 12, wherein the two screws 101 are arranged outside the heat dissipation body 13.

[0045] Preferably, as Figure 2 shown, the lamp housing base 111 and the ground-inserted rod 20 are attached to each other in a tooth surface manner, and then the threaded cooperation between the adjusting screw 102 passing through the lamp housing base 111 and the ground-inserted rod 20 and the locking nut 103 is used to realize the locking of the assembly between the lamp housing base 111 and the ground-inserted rod 20. In this way, when the user needs to adjust the installation angle of the lamp housing base 111 on the ground-inserted rod 20, it can be achieved by screwing the locking nut 103.

[0046] As Figure 3 、 Figure 4As shown, the upper cover 112 of the lamp housing has a light guide surface 1121. The light guide surface 1121 is disposed around the lamp beads 121. Moreover, the light guide surface 1121 can guide the light generated by the lamp beads 121 to emit outward, thereby improving the light output efficiency when the ground socket lamp 100 works. Here, the light guide surface 1121 is conical, and the diameter of the light guide surface 1121 gradually increases in the direction away from the circuit board 12.

[0047] As Figure 5 shown, the lamp housing 11 further includes an O-ring seal 113. The O-ring seal 113 is disposed between the lamp housing base 111 and the upper cover 112 of the lamp housing for assembling and sealing the lamp housing base 111 and the upper cover 112 of the lamp housing. That is to say, the existing O-ring seal 113 on the market can be used for assembling and sealing between the lamp housing base 111 and the upper cover 112 of the lamp housing, which can avoid the mold opening design of the structure required for sealing between the lamp housing base 111 and the upper cover 112 of the lamp housing, thus playing a role in reducing costs. Here, a groove 1111 is formed on the lamp housing base 111, and the groove 1111 is used to accommodate part of the O-ring seal 113.

[0048] As Figure 3 、 Figure 4 shown, the heat sink 13 includes a first plate body 131 and a plurality of second plate bodies 132 connected to each other. The plurality of second plate bodies 132 extend along a first direction and are arranged in parallel with each other. Moreover, the plurality of second plate bodies 132 are arranged at intervals in a second direction in sequence, wherein the second direction is perpendicular to the first direction; wherein, one side surface of the first plate body 131 facing away from the second plate bodies 132 is abutted against the circuit board 12. This can increase the area of the outer surface of the heat sink 13, thereby improving the heat dissipation effect of the heat sink 13 on the circuit board 12. It should be noted that the first plate body 131 and the plurality of second plate bodies 132 are connected as a whole. Here, the material of the heat sink 13 is configured as aluminum alloy. Of course, in other embodiments, the material of the heat sink 13 can also be copper or other materials with high thermal conductivity.

[0049] As Figure 3 、 Figure 4 shown, the lamp body 10 further includes a fixing member 14. The fixing member 14 passes through the circuit board 12 and is threadedly connected to the heat sink 13 for fixing the heat sink 13 to the circuit board 12 and realizing the assembly connection of the heat sink 13 on the circuit board 12, which can facilitate the assembly of the heat sink 13 to the circuit board 12. Here, the fixing member 14 is configured as a bolt or a screw, and the number of the fixing members 14 is configured as two.

[0050] As Figures 1 to 3 and Figure 6As shown, the ground-inserted lamp 100 further includes a lens 30, which is disposed on the light-emitting path of the lamp beads 121; wherein, the color of the lens 30 can be changed. When the ground-inserted lamp 100 works, different colors of light can be emitted by changing the color of the lens 30 to meet different usage requirements. Here, different colors of light emitted by the ground-inserted lamp 100 can be finally achieved by replacing the lens 30 with different colors. Of course, in other embodiments, multiple different color light-transmitting regions can also be integrated on one lens 30, and then by changing the different installation positions of the lens 30, different color light-transmitting regions of the lens 30 can be used for the light emitted by the lamp beads 121.

[0051] Preferably, as Figure 2 , Figure 3 and Figure 6 shown, the ground-inserted lamp 100 further includes a lamp cover 40 and a lamp shade 50. The lamp cover 40 is abutted against the upper cover 112 of the lamp housing and fixedly connected to the upper cover 112 of the lamp housing for carrying the lens 30; the lamp shade 50 is connected to the base 111 of the lamp housing in a threaded manner for pressing the lens 30 placed on the lamp cover 40. That is to say, the ground-inserted lamp 100 can replace the assembly of the lens 30 on the ground-inserted lamp 100 by screwing the lamp shade 50, which is convenient for replacing the lens 30 with different colors on the one hand. It should be noted that the lens 30 is pressed and limited to the lamp cover 40 by the lamp shade 50, so that a waterproof function of the ground-inserted lamp 100 can be achieved by the mutual cooperation between the lens 30 and the lamp shade 50. Here, the lamp cover 40, the upper cover 112 of the lamp housing and the base 111 of the lamp housing can be assembled and connected by sharing a fixing member 14.

[0052] Preferably, as Figure 6 shown, a limiting portion 41 is formed on the lamp cover 40, and a limiting and mating portion 31 is formed on the lens 30. The limiting portion 41 and the limiting and mating portion 31 are in concave-convex mating for limiting the assembly of the lens 30 on the lamp cover 40, which is convenient for the assembly of the lens 30 on the lamp cover 40 on the one hand and ensures the accuracy of the position of the lens 30 when assembled on the lamp cover 40 on the other hand. Here, both the limiting portion 41 and the limiting and mating portion 31 can be configured as hem structures.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0054] Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present utility model, they are within the scope of protection required by the present utility model.
