[0043] The lamp structure has good waterproof performance, high production yield, and the like Figure 1 and Figure 2 The lamp structure includes a lampshade 1, a lamp holder 2, a light guide column 3, a light source plate 4, a cover plate 5, and a power line 6.

[0044] Specifically, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 The lampshade 1 is in a hollow spherical shape, and a mounting port 11 is arranged at the top of the lampshade 1 and communicates with the inner cavity of the lampshade 1. The inner wall of the mounting port 11 is provided with a mounting platform 12, and the circumferential side of the light guide column 3 is provided with an abutting ring table. When the abutting ring table abuts against the mounting platform 12, a part of the light guide column 3 extends into the inner cavity of the lampshade 1 to realize light conduction. The light source plate 4 is arranged on the light guide column 3, and the power line 6 is electrically connected to the light source plate 4 to supply power to the light source plate 4. In this embodiment, the light source plate 4 is preferably in the form of a PCBA plate integrated with LED elements. The manufacturing process of the PCBA plate has a high standardization degree, is convenient to maintain, and effectively reduces maintenance costs and time. The light guide column 3 can be selected from a PC light guide or a PMMA light guide in the prior art, so that the light emitted by the LED can be guided from the PCBA plate into the lampshade 1.

[0045] Further, the inside of the lamp holder 2 is hollow, and the lamp holder 2 is connected to the outer wall of the mounting port 11 of the lampshade 1. A glue injection port 21 is arranged at the top of the lamp holder 2, and glue is configured to be filled into the lamp holder 2 from the glue injection port 21 after the lampshade 1, the light guide column 3, the light source plate 4, and the lamp holder 2 are assembled. That is, in this embodiment, the lampshade 1, the light guide column 3, the light source plate 4, and the lamp holder 2 need to be assembled first, and then glue is injected into the lamp holder 2 through the glue injection port 21 at the top of the lamp holder 2. In this way, the staff can conveniently perform the glue injection operation at the top of the lamp holder 2, and the risk of local glue shortage or glue overflow caused by glue injection after the lampshade 1 is installed is avoided, which effectively improves the waterproof performance and aesthetics of the product and improves the production yield.

[0046] As shown in Figures 2-4 , the lamp holder 2 is in a hollow circular truncated cone structure. The bottom of the lamp holder 2 is connected to the outer wall of the mounting port 11 of the lampshade 1, and the outer wall surface of the lamp holder 2 and the top arc surface of the lampshade 1 form a smooth transition, so that the entire lamp structure is in a water drop shape, improving the aesthetics of the product.

[0047] Specifically, as shown in Figures 2-6As shown, the outer wall of the mounting port 11 protrudes a first clamping block 13, and the inner wall surface of the lamp cap 2 is provided with a first clamping groove 23 corresponding to the first clamping block 13. The first clamping block 13 is clamped with the first clamping groove 23, thereby realizing the detachable connection between the lampshade 1 and the lamp cap 2. In this embodiment, the first clamping block 13 is protrudingly arranged on the entire circumference of the outer wall of the mounting port 11, and the first clamping groove 23 is correspondingly arranged on the circumference of the inner wall of the lamp cap 2, thereby effectively improving the reliability and firmness of the connection between the lamp cap 2 and the lampshade 1. Of course, in other embodiments, the first clamping block 13 can also be provided with a plurality of first clamping blocks 13 arranged at intervals along the circumference of the mounting port 11, and the first clamping groove 23 is correspondingly provided with a plurality of first clamping grooves 23. The first clamping block 13 is clamped with the first clamping groove 23, which can also realize the connection between the lamp cap 2 and the lampshade 1.

[0048] After the lampshade 1 and the lamp cap 2 are preliminarily fixed by the first clamping block 13 and the first clamping groove 23, the adhesive force of the glue injected into the lamp cap 2 can make the connection between the lampshade 1 and the lamp cap 2 more firm, but the glue may also overflow from the connection between the first clamping block 13 and the first clamping groove 23.

[0049] Further, the outer wall of the mounting port 11 further protrudes a stop block 14, which is arranged on the side of the first clamping block 13 away from the opening end of the mounting port 11. The inner wall surface of the lamp cap 2 is further provided with a stop groove 24 corresponding to the stop block 14. When the first clamping block 13 is clamped with the first clamping groove 23, the stop block 14 abuts against the groove wall of the stop groove 24. Since the protruding height of the stop block 14 is greater than the protruding height of the first clamping block 13, the connection between the first clamping block 13 and the first clamping groove 23 is the first line of defense against glue overflow, and the abutment between the stop block 14 and the stop groove 24 is the second line of defense against glue overflow, further preventing glue overflow and effectively avoiding the influence of glue overflow on the appearance of the lamp structure.

[0050] As shown in Figure 2 and Figure 3 , the top surface of the light guide column 3 is recessed to form a containing groove 31, and the light source plate 4 is embedded and mounted in the containing groove 31. In this way, the installation space is utilized reasonably, and the compactness of the lamp structure is improved.

[0051] Specifically, the groove bottom of the containing groove 31 is provided with an adhesive layer, and the light source plate 4 is attached to the adhesive layer. The adhesive layer can be a double-sided adhesive layer, one side of which is attached to the groove bottom of the containing groove 31, and the other side is attached to the light source plate 4. Using a double-sided adhesive layer to fix the light source plate 4 is more convenient and faster than screwing and clamping, and the double-sided adhesive layer also prevents glue from overflowing into the light emitting recessed surface of the light guide column 3, thereby avoiding affecting the optical effect.

[0052] Further specifically, referring to Figure 2 and Figure 3The side of the light source plate 4 is provided with a positioning gap 41, and the inner wall surface of the accommodating groove 31 is provided with a positioning bone 32 matched with the positioning gap 41. When the light source plate 4 is installed, the positioning gap 41 is aligned with the positioning bone 32 and inserted, so that the light source plate 4 can be accurately positioned.

[0053] Further, as shown in Figures 4-6 The inner wall of the lamp holder 2 is provided with a plurality of limiting columns, which are arranged along the circumference of the lamp holder 2. The limiting columns can be pressed against the upper surface of the light source plate 4 and / or the upper surface of the light guide column 3 when the lamp holder 2 is connected with the lampshade 1.

[0054] In this embodiment, the plurality of limiting columns include a first limiting column 25 and a second limiting column 26. The first limiting column 25 is pressed against the light guide column 3 to tightly press the light guide column 3 against the mounting platform 12, which not only fixes the light guide column 3, but also effectively prevents the glue from flowing into the inside of the lampshade 1. The second limiting column 26 is pressed against the light source plate 4 to prevent the light source plate 4 from loosening due to failure of the adhesive layer.

[0055] Continuing to refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 After the glue injection is completed, the cover plate 5 is connected with the lamp holder 2 and seals the glue injection port 21, thereby completing the entire assembly of the lamp structure.

[0056] Specifically, the side of the cover plate 5 facing the lamp holder 2 is provided with a first clamping part 51, and the inner wall of the glue injection port 21 of the lamp holder 2 is correspondingly provided with a first clamping seat 22, and the first clamping part 51 is detachably connected with the first clamping seat 22. In this embodiment, the first clamping part 51 includes a connecting part 511 and a clamping part 512, and the clamping part 512 is protrusively arranged away from the center axis of the cover plate 5 on the side of the connecting part 511. The connecting part 511 drives the clamping part 512 to extend into the lamp holder 2 from the glue injection port 21, and the clamping part 512 can abut on the first clamping seat 22. Through the abutment of the clamping part 512 and the first clamping seat 22, the reliable connection of the cover plate 5 and the lamp holder 2 is realized.

[0057] It can be understood that the cover plate 5 is provided with a through hole for the power line 6 to pass through.

[0058] Optionally, the cover plate 5 is further provided with a hook 52. The hook 52 not only can be used as an operation holding part when the cover plate 5 is moved, but also can realize the hooking installation of the lamp structure, thereby expanding the application range of the lamp structure.

[0059] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to exhaust all the implementation modes.
