[0031] In order to further explain the technical scheme of the utility model, the utility model will be described in detail through specific embodiments.

[0032] Referring to Figures 1 to 4 The utility model provides a kind of LED lamp structure, comprising: radiator 1, bottom plate 2, waterproof ring 3, lamp plate 4, cover plate 5;

[0033] Radiator 1 lower end has the fin 11 of interval arrangement, and the upper end of radiator 1 is shaped with mounting surface 12, and bottom plate 2 is equipped on mounting surface 12;

[0034] Waterproof ring 3 is equipped on the mounting surface 12 of radiator 1, and is surrounded in the outer periphery of bottom plate 2;

[0035] Multiple lamp beads 42 are installed on lamp plate 4, and lamp plate 4 is covered on mounting surface 12;

[0036] Cover plate 5 is covered on mounting surface 12, and is located in the outer side of lamp plate 4, and cover plate upper surface 51 is the flat plane and is light exit surface, and cover plate lower surface 52 is integrally formed with multiple lenses 53 corresponding to the position of each lamp bead 42, and waterproof ring 3 is located in the inner side of cover plate 5, and sealing cavity is formed between cover plate 5 and bottom plate 2 by waterproof ring 3.

[0037] The main improvement of this utility model is that the cover plate 5 covers the top of the entire lamp structure, the upper surface 51 of the cover plate is a flat light-emitting surface, and the lens 53 is integrally formed on the lower surface 52 of the cover plate. The cover plate 5 and the lens 53 are an integral structure, eliminating the need for separate cover plates and lens plates, or for installing a lens bracket inside the light-emitting panel. Therefore, the LED lamp structure of this utility model is simple and compact, reducing the number of gaps between structures and providing better dust and water resistance. Furthermore, the addition of a waterproof ring 3 further enhances the waterproof and dustproof performance, making it more suitable for outdoor use.

[0038] Preferably, the waterproof ring 3 can be made of silicone.

[0039] Furthermore, since the lens 53 is located on the lower surface 52 of the cover plate, and the upper surface 51 of the cover plate is flat (i.e., the light-emitting surface is flat), rather than directly setting the upper surface 51 of the cover plate as a protruding lens 53, the LED light of this invention can be adapted to more installation scenarios when used outdoors. It also reduces the risk of damage caused by collisions and pressure due to a protruding light-emitting surface. The lens 53 is located inside the cover plate 5, and the upper surface 51 of the cover plate, as a flat light-emitting panel, protects the lens, preventing scratches on the lens surface and ensuring good illumination. The light-emitting surface allows the light emitted from each lens to be emitted from the entire surface, resulting in better illumination.

[0040] For details, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 The waterproof ring 3 and the base plate 2 are located in the cavity between the lamp plate 4 and the mounting surface 12. The base plate 2 can be integrally formed or separately mounted on the mounting surface 12 of the heat sink 1. The sealed cavity is formed inside the lamp plate 4, and the base plate 2 is located in the sealed cavity. The base plate 2 is made of a thermally conductive material, such as an aluminum plate or an aluminum alloy plate. It is located between the lamp plate 4 and the mounting surface 12 to assist the heat sink 1 in heat dissipation, so that the heat of the lamp plate 4 can be conducted to the fins 11 of the heat sink 1 through the base plate 2 for dissipation. The mounting surface 12 of the heat sink 1 and the base plate 2 are provided with corresponding wire inlet holes (for easy distinction, they are named mounting surface wire inlet hole 121 and base plate wire inlet hole 21, respectively. The base plate wire inlet hole 21 on the base plate 2 is located on one side edge of the base plate 2 and is formed by the indentation of one side edge of the base plate 2). The wire inlet hole is located in the sealed cavity. The power cord (not shown in the figure) passes through the wire inlet hole into the sealed cavity to electrically connect to the lamp plate 4. In this way, the circuit connecting the lamp plate 4 also has a certain degree of waterproofness.

[0041] Further, the waterproof lock head 6 is further included, the upper end of the waterproof lock head 6 is jointed with the wire inlet hole (the upper end of the waterproof lock head 6 passes through the installation surface wire inlet hole 121, and passes out the bottom plate wire inlet hole 21), the power line enters the sealed cavity after passing through the waterproof lock head 6 and the wire inlet hole, and is electrically connected with the lamp plate 4. When used outdoors, the waterproof lock head 6 prevents water from flowing into the LED lamp along the power line, and further improves the waterproof performance of the LED lamp.

The lamp bead mounting groove 41 on the lamp plate 4 is upwardly protruding, and protrudes towards the lens 53, and the lamp bead 42 can be mounted in the lamp bead mounting groove 41 from below the lamp plate 4. Further, the lens 53 is downwardly protrudingly arranged on the lower surface 52 of the cover plate, and in this embodiment, the lens 53 is in the shape of a circular truncated cone, the size of the lens 53 gradually decreases during the process of outwardly protruding from the lower surface 53 of the cover plate, the lens 53 is provided with a scale armor for refracting light on the side surface, so that the light spot is uniform, and the lens 53 is provided with a concave accommodating cavity 531 corresponding to the lamp bead mounting groove 41, and when the cover plate 5 is covered on the lamp plate 4, the lamp bead mounting groove 41 is embedded in the accommodating cavity 531 of the corresponding lens 53. Therefore, the compactness of the overall structure of the LED lamp can be further improved, and the light emitting effect is improved. The bottom surface of the accommodating cavity 531 forms an incident bottom surface, and an arc compound eye microstructure can also be formed on the incident bottom surface, so that the light spot is further uniform and anti-glare.

[0043] The cover plate 5 is made of transparent plastic material, and has good light transmittance.

[0044] The mounting guide walls 13 are protrudingly arranged on both sides of the installation surface 12 at the upper end of the heat sink 1, the bottom plate 2, the waterproof ring 3, the lamp plate 4 and the cover plate 5 are located between the two mounting guide walls 13, and the plurality of screws 7 are circumferentially distributed around the cover plate 5, the lamp plate 4, the waterproof ring 3 and the installation surface 12 of the heat sink 1, and the screws 7 are sequentially threaded and fixed with the cover plate 5, the lamp plate 4, the waterproof ring 3 and the heat sink 1.
