The overall efficient heat dissipation of the LED lamp is achieved through the mutual cooperation of the radiator 41 and the annular light panel 42, and the secondary utilization of heat and the repelling of mosquitoes are achieved through the design of the connecting ring 10 and the storage box 521. Such a design not only solves the problem of heat dissipation of the lamp, but also increases its practicality.

[0024] Embodiment 2

[0025] See also Figures 1 to 5, on the basis of the first embodiment, the annular lamp panel 42 is fixedly installed on the inner ring surface of the lower barrel cover 2. The inner ring surface of the annular lamp panel 42 is detachably installed with lamp beads 421. The outer ring surface of the annular lamp panel 42 is fixedly installed with reinforcing ribs 423 and heat dissipation fins 422. There are four groups of reinforcing ribs 423 and they are arranged in an equidistant array about the central axis of the annular lamp panel 42. An annular lamp panel 42 is additionally installed on the lower end ring surface of the lower barrel cover 2 to enhance the light effect of the lamp body. By means of the connection of the reinforcing ribs 423, the overall installation strength of the annular lamp panel 42 is improved. The heat dissipation fins 422 are used as heat dissipation elements, and their distribution strategy aims to maximize the use of space to achieve efficient heat dissipation of the lamp beads 421 during the working state, effectively preventing heat from accumulating inside the lamp, thus ensuring the long-term stable operation of the lamp and excellent lighting effects. The upper surface of the annular lamp panel 42 is fixedly connected with a circular cylinder. The upper end of the circular cylinder is fixedly connected with the inner surface of the lower barrel cover 2. Heat dissipation grooves are evenly opened on the inner wall of the circular cylinder. By connecting the circular cylinder at the upper end of the annular lamp panel 42 and through the evenly opened heat dissipation grooves on the circular cylinder, the circular cylinder not only realizes seamless docking with the inner surface of the lower barrel cover 2, but also evenly opens heat dissipation grooves on its inner wall. This design cleverly utilizes the principle of air convection. Through the guidance of the heat dissipation grooves, the heat generated inside the lamp can be quickly and evenly dissipated to the external environment. At the same time, the hollow structure formed between the circular cylinder and the lower barrel cover 2 not only provides a smoother channel for the natural convection of heat, but also enhances the overall aesthetics and structural strength of the lamp.

[0026] Embodiment Three

[0027] Please refer to Figures 1 to 5, on the basis of the second embodiment, the limit installation component includes an annular groove plate 51. The inner ring surface of the annular groove plate 51 is movably connected to the outer surfaces of the upper cylinder cover 1 and the connecting ring 10. Sealing rubber strips are respectively arranged on the inner side surfaces of the annular groove plate 51, and the inner side surfaces of the sealing rubber strips are movably abutted against the outer surfaces of the upper cylinder cover 1 and the connecting ring 10. Heat dissipation square holes 100 are evenly formed on the inner wall of the connecting ring 10; the inner ring surface of the annular groove plate 51 forms a movable connection with the outer surfaces of the upper cylinder cover 1 and the connecting ring 10. This design ensures the flexibility and adaptability of the installation. When installing the annular groove plate 51, the whole annular groove plate 51 is sleeved from the upper end of the upper cylinder cover 1. With the sealing rubber strip installed on the inner annular surface of the annular groove plate 51, the tightness when the annular groove plate 51 is installed with the connecting ring 10 is effectively enhanced, and it is avoided that external dust and impurities enter the interior of the upper cylinder cover 1 through the heat dissipation square holes 100 and affect the normal use of the lamp; a mounting block 511 is fixedly connected to the lower end of the annular groove plate 51. The outer surface of the mounting block 511 is movably connected to a clamping hoop 512. The clamping hoop 512 is fixedly installed on the outer surface of the upper side of the lower cylinder cover 2. Six groups of the mounting blocks 511 and the clamping hoops 512 are arranged in a lamp array about the central axis of the connecting ring 10; when the annular groove plate 51 is pushed to the predetermined installation position, contact occurs between the mounting block 511 and the clamping hoop 512. As the annular groove plate 51 continues to be pressed down, the clamping hoop 512 deforms under the extrusion of the mounting block 511, forming a fastening effect similar to that of a clamping hoop. This design enables multiple groups of clamping hoops 512 to act together to achieve an all-round tight fit and fixation of the mounting block 511, thereby ensuring the overall stability of the annular groove plate 51 in the installation position without displacement. It not only effectively prevents the intrusion of external adverse factors, but also significantly improves the installation stability and reliability of the lamp, providing a solid guarantee for the long-term use of the lamp.

[0028] Embodiment Four

[0029] Please refer to Figures 1 to 5On the basis of the third embodiment, the evaporative insect repellent component 52 includes a storage box 521, which is fixedly mounted on the inner wall of the annular groove plate 51. Circular through holes are evenly provided on the inner wall of the storage box 521, and the storage box 521 as a whole is a frame-shaped structure with one side open; multiple groups of storage boxes 521 are evenly installed on the annular groove plate 51 to accommodate the absorbent cotton blocks 523, and the heat generated by the LED lamp group 3 when working is dissipated outward through the heat dissipation square holes 100. Circular through holes are evenly distributed on the inner wall of the storage box 521. These through holes not only optimize the air circulation path, but also enable the heat generated by the lamp when working to be efficiently dissipated outward through the heat dissipation square holes 100, and volatilize faster through the through holes of the storage box 521, which effectively improves the heat dissipation performance of the lamp. The storage box 521 has an upper end through which a liquid injection hole 522 is connected, one end of which penetrates the upper surface of the annular groove plate 51, and an absorbent cotton block 523 is movably installed on the inner surface of the storage box 521; when the absorbent cotton block 523 needs to be supplemented, the insect repellent is injected through the liquid injection hole 522, and the absorbent cotton block 523 movably installed on the inner surface of the storage box 521 serves as a carrier of the insect repellent, and its design fully considers the convenience of use and the maximization of the effect. When the absorbent cotton block 523 needs to be supplemented, the user only needs to accurately inject an appropriate amount of insect repellent through the liquid injection hole 522, which not only avoids the risk of excessive insect repellent liquid infiltrating into the interior of the lamp through the heat dissipation square hole 100, but also ensures the continuity of the insect repellent effect and reduces the waste of resources.

[0030] The working principle and use process of the utility model are as follows: in actual operation, first, the annular groove plate 51 is sleeved as a whole from the upper end of the upper cylinder cover 1, and the sealing strip installed on the inner ring surface of the annular groove plate 51 is used to effectively enhance the tightness of the annular groove plate 51 and the connecting ring 10 during installation. When the annular groove plate 51 is pushed to the predetermined installation position, the embedded block 511 and the clamping clamp 512 come into contact with each other, and as the annular groove plate 51 is continuously pressed downward, the clamping clamp 512 is squeezed by the embedded block 511 and deformed, forming a tightening effect similar to a clamp. This design enables multiple groups of clamping clamps 512 to work together to fully tighten the embedded block 511. The tight fit and fixation in position ensure that the annular groove plate 51 as a whole is stable in the installation position. Then, the absorbent cotton block 523 movably installed on the inner surface of the storage box 521 serves as a carrier of the insect repellent liquid. When the absorbent cotton block 523 needs to be replenished, the user only needs to accurately inject a proper amount of insect repellent liquid through the injection hole 522. Then, the heat generated by the lamp during operation can be efficiently dissipated outward through the heat dissipation square hole 100. At the same time, the heat emitted by the LED lamp is reused for the second time. The absorbent cotton block 523 inside the storage box 521 is evaporated by transmitting heat, which accelerates the volatilization speed of the absorbent cotton block 523 and further improves the repelling of mosquitoes around the lamp.
