[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] Example 1

[0040] refer to Figures 1 to 5 This embodiment provides a lamp body structure, including a frame 1, a first sealing assembly 2, and a second sealing assembly 3. The frame 1 includes seamlessly connected side panels 11, which surround a light-emitting cavity 12. The light-emitting cavity 12 is provided with a first opening 13 and a second opening 14. The first opening 13 is provided at the light-emitting end of the frame 1. The side panels 11 are provided with a fixing groove 15. In this embodiment, the fixing groove 15 extends from the light-emitting end of the frame 1 toward the second opening 14. In this embodiment, the frame 1 is a rectangular frame structure. In other embodiments, the frame 1 can also be a triangular, pentagonal, or hexagonal frame structure having a light-emitting cavity.

[0041] The first sealing assembly 2 includes a light-transmitting member 21 and an elastic sealing member 22. The elastic sealing member 22 is fixedly connected to the edge of the light-transmitting member 21. The light-transmitting member 21 covers the first opening 13, and the elastic sealing member 22 is embedded in the fixing groove 15. In this embodiment, the edge of the light-transmitting member 21 is fixedly attached to the light-emitting end of the frame 1. The second sealing assembly 3 includes a back panel 31 and fasteners 32. The back panel 31 is fixedly connected to the side panel 11 via the fasteners 32 and covers the second opening 14.

[0042] It is understood that the opening of the fixing groove 15 is on the same horizontal plane as the first opening, and the fixing groove 15 is arranged around the frame 1 in an entire circle; the light-transmitting member 21 is a sheet-like or membrane-like structure, which covers the first opening 13 to achieve both sealing and light transmission; the elastic sealing member 22 is connected to the edge of the light-transmitting member 21 and is arranged around the edge of the light-transmitting member 21 in an entire circle. By fitting the elastic sealing member 22 into the fixing groove 15, the edge of the light-transmitting member 21 can be tightly fitted with the side panel 11, so that the first opening 13 is completely sealed, and there is no gap at the connection between the light-transmitting member 21 and the frame 1, effectively preventing mosquitoes from entering the interior of the lamp, with good protection effect, simple structure, and convenient installation. On this basis, through the cooperation of the back plate 31 and the fastener 32, the second opening 14 can also be closed, making the light-emitting cavity 12 a completely sealed space, which can effectively prevent the entry of mosquitoes or foreign objects and achieve ideal protection effect.

[0043] In this embodiment, the side panels 11 are made of aluminum profiles. There are four side panels 11, which are connected by seamless welding and then subjected to a powder coating process to improve the sealing of the joints between the side panels 11. In some embodiments, the multiple side panels 11 can also be a one-piece structure. The seamless connection between the side panels 11 can eliminate gaps in the frame 1, effectively preventing light leakage while also ensuring that mosquitoes cannot enter the interior of the lamp, which helps to further improve the sealing of the lamp.

[0044] In some embodiments, a plurality of retaining grooves 151 are provided on two opposing inner sidewalls of the fixing groove 15, and a plurality of retaining protrusions 221 are provided on the two opposing sidewalls of the elastic seal 22. The shape of the retaining protrusions 221 matches the shape of the retaining grooves 151, and the retaining protrusions 221 engage with the retaining grooves 151. In this embodiment, both the retaining grooves 151 and the retaining protrusions 221 are strip-shaped. The cooperation between the retaining grooves 151 and the retaining protrusions 221 allows the elastic seal 22 to engage with the inner sidewalls of the fixing groove 15, thereby improving the connection stability between the elastic seal 22 and the fixing groove 15, preventing the elastic seal 22 from loosening or detaching, and further tightening the connection between the elastic seal 22 and the fixing groove 15, further improving the sealing performance of the lamp.

[0045] In some embodiments, the retaining groove 151 includes a bottom surface 1511, a first inclined surface 1512, and a second inclined surface 1513. The first inclined surface 1512 and the second inclined surface 1513 are provided on both sides of the bottom surface 1511. In the same retaining groove 151, the first inclined surface 1512 is farther away from the light emitting end than the second inclined surface 1513. The first inclined surface 1512 is used to guide the elastic seal 22 into the fixing groove 15, and the second inclined surface 1513 is used to guide the elastic seal 22 out of the fixing groove 15.

[0046] It can be understood that, taking the limiting protrusion 221 at the front end as an example, when the elastic seal 22 is pressed into the fixed groove 15, the limiting protrusion 221 first enters the first limiting groove 151, and then moves along the first inclined surface 1512 of the first limiting groove 151 to enter the next limiting groove 151, thereby passing through several limiting grooves 151 in sequence and reaching the last limiting groove 151; when the elastic seal 22 is pulled out from the fixed groove 15, the limiting protrusion 221 moves along the second inclined surface 1513 of the last limiting groove 151 to enter the previous limiting groove 151, thereby passing through several limiting grooves 151 in sequence and finally leaving the fixed groove 15 along the second inclined surface 1513 of the first limiting groove 151.

[0047] like Figure 5As shown, the first inclined surface 1512 and the second inclined surface 1513 form an angle α and an angle β with the bottom surface 1511 respectively, wherein the angle α is smaller than the angle β. As a result, the inclination angle of the first inclined surface 1512 is relatively gentle, while the inclination angle of the second inclined surface 1513 is relatively steep, so that the elastic seal 22 can enter the fixing groove 15 more easily, while making the process of the elastic seal 22 escaping from the fixing groove 15 more difficult, forming a structural design that is easy to enter and difficult to exit, further improving the connection stability between the elastic seal 22 and the fixing groove 15, and ensuring the sealing effect of the lamp. As a further optimization, the range of angle α is 20 to 25°, and the range of angle β is 43 to 48°. In this embodiment, the angle α is preferably 21°, and the angle β is preferably 45°.

[0048] In this embodiment, the light-transmitting member 21 is a light-transmitting soft film, and the elastic sealing member 22 is a silicone bead. The light-transmitting soft film and the silicone bead are securely connected via a woven fabric. When the silicone bead is engaged with the fixing groove 15, the light-transmitting soft film fits tightly against the opening of the fixing groove 15. Because the light-transmitting soft film itself has a certain degree of ductility, it exerts a certain amount of tension on the silicone bead, causing the inner side surface of the elastic sealing member 22 to fit tightly against the inner wall of the fixing groove 15. This further improves the sealing performance of the connection between the frame 1 and the first sealing assembly 2, thereby enhancing the overall sealing performance of the lamp.

[0049] The lamp body structure of this embodiment, by embedding the elastic sealing part in the fixing groove, makes the light-transmitting part fit into the first opening, thereby improving the sealing of the lamp, effectively preventing mosquitoes from entering, eliminating the need for cleaning and maintenance of the lamp, and has a simple structure and convenient installation; through the cooperation of the limiting groove and the limiting protrusion, the elastic sealing part and the fixing groove are engaged with each other, thereby improving the connection stability of the elastic sealing part and the fixing groove, which is conducive to further improving the sealing of the lamp; by setting the inclination angle of the first inclined surface to be smaller than the inclination angle of the second inclined surface, the elastic sealing part can easily enter the fixing groove but is difficult to come out of the fixing groove, thereby further improving the connection stability of the elastic sealing part and the fixing groove; by selecting a light-transmitting soft film as the light-transmitting part, the sealing performance of the lamp can be further improved, and a better protection effect can be achieved.

[0050] Example 2

[0051] As a further optimization of Example 1, Figures 1 to 5 Based on the reference Figure 6The second sealing assembly 3 also includes a filling piece 33. The side panel 11 extends toward the light-emitting cavity 12 at the position of the second opening 14 to form a connecting end 111. A mounting groove 112 is provided on the connecting end 111. The mounting groove 112 is opened along the second opening 14 in a direction away from the first opening 13. The filling piece 33 is disposed between the back panel 31 and the connecting end 111. The fastener 32 is fixedly connected to the mounting groove 112, and the fastener 32 is pressed against the back panel 31 and the filling piece 33. In this embodiment, the fastener 32 is a fixing screw. The back panel 31 and the filling piece 33 are both located on the side of the connecting end 111 close to the light-emitting cavity 12. When the fixing screw is connected to the mounting groove 112, the head of the fixing screw presses against the edge of the back panel 31 and the filling piece 33.

[0052] The connecting end 111 is provided with a first attachment position 1111 and a second attachment position 1112. The first attachment position 1111 and the second attachment position 1112 are respectively located on the side of the mounting slot 112 away from the side panel 11 and on the side of the mounting slot 112 closer to the side panel 11. It should be noted that the filler 33 is attached to the first attachment position 1111, and the edge of the back panel 31 abuts the filler 33. When the fastener 32 is installed in the mounting slot 112, the head of the fastener 32 on the side closer to the side panel 11 directly abuts the second attachment position 1112, while the head of the fastener 32 on the side farther from the side panel 11 abuts the back panel 31. Since the head of the fastener 32 close to the side panel 11 directly abuts the second attachment position 1112, and the filler 33 and the back panel 31 need to be accommodated between the head of the fastener away from the side panel 11 and the first attachment position 1111, there is a height difference H0 between the first attachment position 1111 and the second attachment position 1112.

[0053] By connecting the fasteners 32 to the mounting slots 112, the back panel 31 can be covered at the second opening 14. The connection between the back panel 31 and the side panels 11 is filled with a filler 33. The filler 33 is arranged in a full circle, thereby eliminating the gap between the back panel 31 and the side panels 11 and achieving a sealing effect. In this embodiment, the filler 33 is an EVA pad. The EVA pad has good elasticity and can provide good filling and achieve a better sealing effect.

[0054] The filler 33 is snugly attached to the first attachment location 1111, and the original thickness H1 of the filler 33 is related to H0 by the equation: H1 > H0. The compressed thickness of the filler 33 is H2, and the thickness of the back panel 31 is H3, satisfying the equation: H2 + H3 ≥ H0. This ensures that when the fastener 32 is properly secured to the mounting slot 112, the filler 33 is fully compressed, completely filling the gap between the back panel 31 and the side panel 11. This further improves the lamp's sealing performance, providing enhanced protection and effectively preventing insects from entering the lamp.

[0055] The lamp body structure of this embodiment eliminates the gap at the connection between the back panel and the side panel by setting a filling piece, thereby improving the sealing of the lamp; by setting the thickness of the filling piece to be greater than the height difference between the first attachment position and the second attachment position, it can ensure that the gap at the connection between the back panel and the side panel is completely filled, further improving the sealing effect.

[0056] Example 3

[0057] exist Figures 1 to 6 Based on the reference Figure 7 This embodiment provides a lamp, including a light source assembly 100 and a lamp body structure 200 according to Embodiment 1 or 2. The light source assembly 100 is installed in a light-emitting cavity 12. The cooperation between the first sealing assembly 2 and the frame 1, and the cooperation between the second sealing assembly 3 and the frame 1, makes the light-emitting cavity 12 a fully sealed cavity. Installing the light source assembly 100 in the light-emitting cavity 12 effectively prevents foreign objects such as mosquitoes from entering the interior of the lamp, ensuring the normal lighting effect of the lamp and effectively avoiding the inconvenience caused by regular cleaning and maintenance.

[0058] The lamp of this embodiment improves the sealing performance of the lamp by adopting a lamp body structure, enhances the overall protection effect of the lamp, prevents mosquitoes from entering the interior of the lamp, eliminates the need for cleaning and maintenance of the lamp, and provides users with a better user experience.

Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these obvious alternative forms are all within the scope of protection of the present invention.
