[0035] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0036] Embodiment

[0037] Please refer to Figures 1-6 , the ground - inserted lamp provided by this application includes a light source assembly 1, a lamp post 2, a ground - inserted post 3, and a power cord 4. The light source assembly 1, the lamp post 2, and the ground - inserted post 3 are arranged in sequence from top to bottom. The power cord 4 is arranged inside the lamp post 2 and is connected to the light source assembly 1. The cross - sectional shapes of the light source assembly 1, the lamp post 2, and the ground - inserted post 3 are all circular, and the cross - sectional area of the light source assembly 1 is larger than the cross - sectional area of the lamp post 2, which is convenient for the multi - angle light emission of the light source assembly 1.

[0038] For the purpose of achieving rapid installation or replacement of the light source assembly 1, the light source assembly 1 is detachably connected to the lamp post 2. Specifically, the light source assembly 1 includes an installation module 11, a first lamp bead 12, a second lamp bead 13, a lamp bead mounting plate 14, a diffusion plate 15, and a light guide plate 16. The installation module 11 is plugged into the lamp post 2, and the diffusion plate 15 and the light guide plate 16 and the installation module 11 form a receiving cavity, and the first lamp bead 12, the second lamp bead 13, and the lamp bead mounting plate 14 are all arranged in the receiving cavity.

[0039] More specifically, the installation module 11 includes an outer tube 111 and an inner tube 112. The outer tube 111 is a hollow ring structure, and several steps 1111 are provided on the inner wall of the outer tube 111. The several steps 1111 are respectively arranged at the top, middle, and bottom of the outer tube 111 for installing the diffusion plate 15, the lamp bead mounting plate 14, and the light guide plate 16. One end of the inner tube 112 is arranged inside the outer tube 111, and the other end protrudes from the outer tube 111, so that the cross-section of the installation module 11 is integrally in a T shape. A wire passing hole 113 and an annular groove 114 are also provided on the inner tube 112. The wire passing hole 113 is used for the routing of the power line 4, and the annular groove 114 is used for connecting to the lamp post 2. Exemplarily, as Figure 4 shown, the inner tube 112 includes a wide diameter end 1121 and a narrow diameter end 1122. The wide diameter end 1121 is arranged inside the outer tube 111, and the narrow diameter end 1122 protrudes from the outer tube 111, and the cross-section formed with the outer tube 111 is in a T shape; the wiring hole is arranged at the wide diameter end 1121, and the annular groove 114 is arranged at the narrow diameter end 1122. In order to better achieve the socket connection between the installation module 11 and the lamp post 2, the installation module 11 further includes an annular ring 5. The annular ring 5 is arranged at the ring groove, and through the annular ring 5, the friction force between the inner tube 112 and the lamp post 2 is increased, so that the inner tube 112 can be stably socketed on the lamp post 2.

[0040] The diffusion plate 15 and the light guide plate 16 are arranged in parallel and symmetrically at the upper and lower ends of the outer tube 111, and form a receiving cavity with the outer tube 111. Specifically, the diffusion plate 15 is a solid flat plate, and the diffusion plate 15 is adapted to the outer tube 111. The diffusion plate 15 is fixed at the top step 1111 of the outer tube 111 by fixing glue, which can not only achieve the light transmission function but also the waterproof and dustproof functions. The light guide plate 16 is fixed at the bottom step of the outer tube 111 by fixing glue. In order to facilitate the installation of the inner tube 112, an installation through hole is provided in the central area of the light guide plate 16. The area of the installation through hole is smaller than the wide diameter end 1121 of the inner tube 112 and is adapted to the narrow diameter end 1122 of the inner tube 112, so that the inner tube 112 can pass through the installation through hole and abut against the light guide plate 16.

[0041] The lamp bead mounting plate 14 is arranged in the mounting module 11. The first lamp bead 12 is arranged above the lamp bead mounting plate 14, and the light emitting direction of the first lamp bead 12 is upward, that is, the light emitting direction of the first lamp bead 12 faces the diffusion plate 15. The second lamp bead 13 is arranged below the lamp bead mounting plate 14, and the light emitting direction of the second lamp bead 13 is downward, that is, the light emitting direction of the second lamp bead 13 faces the light guide plate 16. Specifically, the lamp bead mounting plate 14 is arranged at the step in the middle of the outer tube 111, and the lower surface of the lamp bead mounting plate 14 abuts against the upper surface of the inner tube 112. In order to improve the stability of the lamp bead mounting plate 14, an adhesive layer is provided on the outer edge of the lamp bead mounting plate 14, and the lamp bead mounting plate 14 is fixed in the outer tube 111 by the adhesive.

[0042] Exemplarily, in order to adapt to different application scenarios, the first lamp bead 12 is warm white light, the second lamp bead 13 is green light, and the number of the first lamp beads 12 is greater than the number of the second lamp beads 13, so that the light passing through the diffusion plate 15 can be more than the light passing through the light guide plate 16. Preferably, the color temperature of the warm white light of the first lamp bead is 4000K, so that the light emitted by the first lamp bead can be brighter and farther, and thus a more obvious brightness difference can be achieved. In practical applications, when the ground lamp is inserted in the grass or flower bed, the tree above is illuminated by the first lamp bead 12, and the grass or flower bed below is illuminated by the second lamp bead 13, thereby increasing the lighting atmosphere of the entire environment and further increasing the application scenarios of the ground lamp. Compared with the existing ground lamp that can only perform a single function of illuminating the flower bed, grass or tree, the ground lamp provided in this application not only satisfies the above functions, but also can illuminate the flower bed, grass and tree at the same time, effectively reducing the number layout of the ground lamps, reducing the cost and improving the lighting atmosphere.

[0043] The lamp post 2 is integrally of a circular tube structure, that is, a hollow structure is provided inside the lamp post 2, and the power line 4 is arranged at the hollow structure and electrically connected to the light source assembly 1. Further, for the convenience of wiring, a waist hole 21 is also provided on the lamp post 2. The waist hole 21 is arranged in the lower half of the lamp post 2, and the power line 4 passes through the waist hole 21 and extends outwards, so as to facilitate wiring.

[0044] In order to realize the detachable connection between the lamp post 2 and the ground plug post 3, the ground-inserted lamp further includes a connecting piece 6, and an external thread is provided on the connecting piece 6. Internal threads adapted to the external thread are provided at the bottom end of the lamp post 2 and the top end of the ground plug post 3. During installation, first connect the connecting piece 6 to the ground plug post 3, and then connect the lamp post 2 to the other end of the connecting piece 6 until the bottom end of the lamp post 2 abuts against the bottom end of the ground plug post 3, thereby fixing the lamp post 2 on the ground plug post 3.

[0045] In order to facilitate inserting the ground plug post 3 into the ground, the ground plug post 3 includes a cylindrical part 31 and a pointed part 32. The cross-sectional area of the cylindrical part 31 is the same as the cross-sectional area of the lamp post 2, and the pointed part 32 is integrally in an inverted slope shape. Specifically, the pointed part 32 includes a cut surface 321 and a straight wall 322, and the shape of the cut surface 321 is an ellipse; the included angle (a) between the cut surface 321 and the straight wall 322 is 15-20 degrees, preferably, the included angle (a) is 17 degrees. By setting the cut surface 321 as an ellipse, the contact area between the ground plug post 3 and the land can be increased. Compared with the conical shape, the pointed part 32 of the present application can make the ground plug post 3 be inserted into the soil more stably. By setting the included angle between the cut surface 321 and the straight wall 322 to 15-20 degrees, compared with setting a smaller included angle which is likely to cause the problem of over-concentrated stress at the bottom end and instability, or setting a larger included angle which is likely to cause a large insertion resistance, the pointed part 32 provided in the present application can reduce the friction force between the ground plug post 3 and the land while meeting the stability, making the installation more labor-saving.

[0046] In order to further improve the waterproof performance, the ground-inserted lamp further includes a waterproof joint 7, and the waterproof joint 7 is connected to the inner tube 112. Specifically, an external thread is provided on the waterproof joint 7, and an internal thread is provided inside the inner tube 112, and the connection between the waterproof joint 7 and the inner tube 112 is realized through a threaded structure. For the convenience of installation, the power line 4 is arranged on the waterproof joint.

[0047] It should be noted that: in order to improve the strength and stability of the ground-inserted lamp, the lamp post 2, the ground-insert rod 3 and the installation module 11 are all made of stainless steel or aluminum alloy. In order to better adapt to the surrounding environment, a layer of colored paint is sprayed on the surfaces of the lamp post 2 and the ground-insert rod 3. For example, when inserted on the grass, a layer of green paint can be sprayed; when inserted in the flower bed, the corresponding color paint can be sprayed according to the color of the blooming flowers.

[0048] In this embodiment, the ground-inserted lamp of the present application includes a light source assembly, a lamp post, a ground-insert rod and a power cord. During installation, the power cord can be first placed into the lamp post, then the light source assembly is plugged onto the lamp post, and the power cord is taken out from the waist hole. Then the connector is connected to the lamp post, and then the connector is connected to the ground-insert rod, thus completing the assembly of the entire ground-inserted lamp. Then the ground-inserted lamp is inserted into the ground to complete the installation of the ground-inserted lamp. Or, the ground-insert rod can be first inserted into the ground, then the connector is installed, and then the lamp post with the plugged light source assembly is rotated onto the connector to complete the installation of the entire ground-inserted lamp. Compared with the existing ground-inserted lamps, the solution provided by the present application enables simpler and faster installation, and can be quickly installed without professionals. Moreover, when any part of the lampshade or the base is damaged, only the damaged part needs to be replaced, thus greatly reducing the usage cost. At the same time, the application of the ground-inserted lamp provided by the present application can be diversified, effectively improving the versatility and practicality of the ground-inserted lamp and meeting the needs of users.

[0049] It should be noted that a microcontroller connected to the first lamp bead and the second lamp bead can also be provided, and the microcontroller is used to control the on and off of the first lamp bead and / or the second lamp bead, thereby further enriching the effects of the ground-inserted lamp.
