The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0059] Example 1

[0060] This embodiment provides a lighting fixture structure that effectively achieves waterproof sealing, improving service life and user experience. This lighting fixture structure can be, but is not limited to, outdoor spotlights or other LED lighting fixtures. Figure 1 As shown, the lamp structure includes a housing 1, a cover 2, and a pressure cap 3.

[0061] Specifically, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The housing 1 includes a mounting cavity 11 and an opening 12 communicating with the mounting cavity 11. A lamp panel 13 is installed inside the mounting cavity 11. The mounting cavity 11 provides installation space for the lamp panel 13 and protects it from direct contact with the outside environment, preventing damage such as impacts or water immersion. The opening 12 of the housing 1 faces the light-emitting side of the lamp panel 13, allowing light emitted from the lamp panel 13 to be emitted through the opening 12 and illuminate the area to be lit.

[0062] In this embodiment, the housing 1 is cylindrical in shape to facilitate manufacturing. Mounting posts 16 are provided inside the housing 1, and multiple mounting posts 16 are arranged in an array. The lamp panel 13 is fixed to the mounting posts 16 by bolts or screws. Of course, in other embodiments, the housing 1 can also be cylindrical or other structures, as long as it allows for the installation of the lamp panel 13; no limitation is made here.

[0063] Continue to refer to Figures 1-3 , Figure 5 and Figure 6 The lampshade 2 includes a lampshade 21 and a connecting part 22, which is arranged around the periphery of the lampshade 21. A positioning ring 111 is provided on the inner wall of the mounting cavity 11 near the opening 12. The connecting part 22 abuts against the positioning ring 111 to achieve initial positioning and connection between the lampshade 2 and the housing 1. The lampshade 21 is located on the side of the connecting part 22 away from the lamp plate 13. A sealant reservoir 14 is formed between the inner wall of the mounting cavity 11, the connecting part 22, and the outer wall of the lampshade 21. The sealant reservoir 14 is used to fill and store sealant. In other words, after the sealant cures, it not only provides a seal, effectively preventing external moisture from entering the lamp structure and ensuring its normal operation, but also reinforces the connection between the lampshade 2 and the housing 1, improving the reliability of the connection between them.

[0064] Understandably, the cover 2 is made of transparent materials, such as transparent plastic, acrylic or glass, to avoid blocking light and ensure the illumination effect of the lamp structure.

[0065] Specifically, a connecting post 15 is also provided inside the housing 1. The top surface of the connecting post 15 is flush with the positioning ring platform 111. The connecting post 15 can assist the positioning ring platform 111 in positioning the cover 2. The connecting part 22 can be fixed to the connecting post 15 by bolts or screws to further improve the reliability of the connection between the cover 2 and the housing 1.

[0066] Preferably, multiple connecting posts 15 are provided, and the multiple connecting posts 15 are distributed in an array to ensure that the force on the connecting part 22 of the cover 2 is balanced.

[0067] Continue to refer to Figure 1 and Figure 2 The pressure cap 3 is fastened to the opening 12 of the housing 1 and partially presses against the lampshade 21 to further improve the reliability and integrity of the connection between the pressure cap 3, the housing 1 and the cover 2.

[0068] Specifically, such as Figures 1-3 As shown, the pressure cap 3 is annular, and a connecting ring platform 31 is provided along the circumference of the outer ring of the pressure cap 3. When the pressure cap 3 is fastened to the opening 12 of the housing 1, the connecting ring platform 31 can be inserted into the opening 12 and abut against the inner wall of the mounting cavity 11, and the bottom of the inner ring of the pressure cap 3 presses against the lampshade 21. The connecting ring platform 31 can increase the contact area between the pressure cap 3 and the housing 1, ensuring the reliability of the connection between the housing 1 and the pressure cap 3. The connecting ring platform 31 can also play a guiding and positioning role when the pressure cap 3 and the housing 1 are mated.

[0069] Preferably, the pressure cap 3 is detachably connected to the housing 1. The inner wall of the mounting cavity 11 around the opening 12 is provided with a plurality of locking blocks 17, and the insertion ring 31 is provided with a plurality of corresponding locking slots 34. When the insertion ring 31 is inserted into the opening 12, the locking blocks 17 can be locked into the corresponding locking slots 34, thereby realizing the connection between the pressure cap 3 and the housing 1.

[0070] More specifically, such as Figure 2 and Figure 3 As shown, when the pressure cap 3 is engaged with the opening 12 of the housing 1, the pressure cap 3 can seal the opening of the glue storage tank 14, thereby further improving the sealing and waterproofing effect of the lamp structure.

[0071] Optionally, a pressing ring platform 32 is provided along the circumference of the inner ring of the pressure cover 3, and the bottom surface of the inner ring of the pressure cover 3 and the pressing ring platform 32 can respectively abut against the top surface and side wall of the lampshade 21. With this arrangement, the lampshade 21 can be reliably pressed against the housing 1. At the same time, the pressing ring platform 32 can also limit the lampshade 21 and prevent the lampshade 21 from being misaligned or tilted.

[0072] Furthermore, the pressing ring 32 and the insertion ring 31 are spaced apart, forming an overflow groove 33 between them. When the cover 3 is engaged with the opening 12 of the housing 1, the overflow groove 33 connects with and communicates with the storage tank 14. It is understandable that if the storage tank 14 contains a large amount of sealant, when the insertion ring 31 is inserted into the opening 12 of the housing 1, i.e., when the insertion ring 31 is inserted into the storage tank 14, the sealant in the storage tank 14 will overflow. The overflow groove 33 is designed to store the overflowing sealant, preventing it from overflowing and affecting the connection between the cover 2 and the housing 1, and ensuring the aesthetic appearance of the lamp structure.

[0073] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the lamp structure also includes a wiring harness assembly 4. A wire-through hole 113 is provided on the housing 1, through which the wiring harness assembly 4 passes. One end of the wiring harness assembly 4 is connected to the lamp board 13, and the other end is connected to an external power source. The wiring harness assembly 4 is used to achieve a conductive connection between the power source and the lamp board 13.

[0074] Specifically, a potting groove 112 is provided on the side of the housing 1 away from the opening 12, and a wire passage hole 113 is formed in the groove wall of the potting groove 112. The potting groove 112 is configured to inject sealant after the wire harness assembly 4 is installed. It can be understood that when the sealant in the potting groove 112 cures, the cured sealant can seal the connection between the wire harness assembly 4 and the wire passage hole 113, preventing moisture from entering the mounting cavity 11 from the connection between the wire harness assembly 4 and the wire passage hole 113, thereby affecting the normal use of the lamp board 13 and ensuring the service life of the lamp structure; the cured sealant can also fix the wire harness assembly 4, preventing the wire harness assembly 4 from being pulled out of the housing 1 during installation or relocation.

[0075] More specifically, such as Figure 4As shown, in this embodiment, the wire harness assembly 4 includes a connecting wire 41 and a mounting buckle 42 sleeved and fixed to the connecting wire 41. The mounting buckle 42 includes a first snap-fit ​​portion 421, a transition portion 422, and a second snap-fit ​​portion 423 connected in sequence. The cross-sectional dimensions of the first snap-fit ​​portion 421 and the second snap-fit ​​portion 423 are both larger than the cross-sectional dimension of the transition portion 422. That is, the mounting buckle 42 forms a snap-fit ​​groove at the outer periphery of the transition portion 422. When the first snap-fit ​​portion 421 passes through the wire hole 113, the shell wall of the housing 1 on the periphery of the wire hole 113 is snapped into the snap-fit ​​groove. That is, the inner wall of the housing 1 on the periphery of the wire hole 113 abuts against the stepped surface formed between the first snap-fit ​​portion 421 and the transition portion 422, and the outer wall of the housing 1 on the periphery of the wire hole 113 abuts against the stepped surface formed between the second snap-fit ​​portion 423 and the transition portion 422. The structural design of the mounting buckle 42 can improve the reliability of the connection between the wire harness assembly 4 and the housing 1, and also improve the sealing performance of the connection between the mounting buckle 42 and the housing 1.

[0076] Preferably, the cross-sectional dimension of the first latching portion 421 gradually decreases along the direction away from the transition portion 422. This arrangement allows a guide slope to be formed at the end of the first latching portion 421 away from the transition portion 422, facilitating the passage of the first latching portion 421 through the wire hole 113.

[0077] like Figure 2 and Figure 6 As shown, the lamp structure also includes a breather 5. The breather 5 is installed on the side of the housing 1 away from the opening 12, and is used to maintain pressure balance between the inside of the mounting cavity 11 and the outside of the housing 1. The structure and working principle of the breather 5 are prior art, and will not be described in detail here.

[0078] Example 2

[0079] This embodiment provides a lamp structure that is basically the same as the lamp structure provided in Embodiment 1, such as... Figures 8-10 As shown, the difference between this embodiment and Embodiment 1 lies in the specific structure of the wire harness assembly 4.

[0080] In this embodiment, the wiring harness assembly 4 includes a connecting wire 41 and a connector 43. The connector 43 is fixedly connected to the connecting wire 41, the connecting wire 41 passes through a wire hole 113, and the connector 43 abuts against the outer wall of the housing 1 around the wire hole 113. Specifically, the connector 43 has a T-shaped structure and is injection molded onto the outer periphery of the connecting wire 41. The connector 43 includes a vertically fixed connecting lug and an insertion part. The insertion part can be inserted into the wire hole 113 and extend into the mounting cavity 11, and the connecting lug abuts against the outer wall of the housing 1 around the wire hole 113, thereby realizing the connection between the wiring harness assembly 4 and the housing 1.

[0081] Furthermore, to improve the sealing effect between the connector 43 and the housing 1, the wiring harness assembly 4 also includes a seal 45, which is sandwiched between the connector lug and the outer wall of the housing 1. In this embodiment, the seal 45 can be a sealing ring as used in the prior art.

[0082] Furthermore, to improve the reliability of the connection between the connector 43 and the housing 1, the wiring harness assembly 4 also includes a fastener 44. A first connection hole is formed on the connector lug, and a second connection hole is formed on the housing 1. The fastener 44 passes through the first connection hole and the second connection hole in sequence, thereby achieving a reliable connection between the connector lug and the housing 1. Exemplarily, the fastener 44 can be a bolt, screw, or rivet, etc., and there is no limitation here.

[0083] Example 3

[0084] This embodiment provides a lamp structure that is basically the same as the lamp structure provided in Embodiment 1, such as... Figures 11-16 As shown, the difference between this embodiment and Embodiment 1 is that the lamp structure also includes a fixed bracket 6.

[0085] Specifically, such as Figure 11 As shown, a mounting part 18 is provided on the housing 1, and the mounting part 18 is rotatably connected to the fixed bracket 6. An angle adjustment structure is provided between the mounting part 18 and the fixed bracket 6. The angle adjustment structure can lock the mounting part 18 and the fixed bracket 6, thereby realizing the adjustment of the illumination angle of the lamp structure.

[0086] This embodiment provides an angle adjustment structure, which includes a connecting screw 71, a spring washer 72, a flat washer 73, and a limiting connecting nut 74. (Refer to...) Figures 12-14 The mounting part 18 has a first connecting hole 181 through it. The fixed bracket 6 has two connecting lugs 61, each with a second connecting hole 611 corresponding to the first connecting hole 181. The two connecting lugs 61 can abut against both sides of the mounting part 18, making the second connecting hole 611 coaxial with the first connecting hole 181. The connecting screw 71 passes through the second connecting hole 611 on one side, the first connecting hole 181 on the other side, and then is screwed into the limiting connecting nut 74, thereby realizing the rotatable connection between the mounting part 18 and the fixed bracket 6.

[0087] Understandably, both the spring washer 72 and the flat washer 73 are fitted onto the shank of the connecting screw 71. When the connecting screw 71 connects the mounting part 18 and the fixed bracket 6, the spring washer 72 and the flat washer 73 are sandwiched between the head of the connecting screw 71 and the connecting lug 61 on one side, with the spring washer 72 located on the side closer to the head of the connecting screw 71. The spring washer 72 provides preload when the connecting screw 71 and the limiting connecting nut 74 are tightened, thereby generating friction between the contact surfaces of the mounting part 18 and the fixed bracket 6, thus ensuring that the lamp structure can be locked at a certain angle without rotation. When it is necessary to adjust the illumination angle of the lamp structure, simply rotate the housing 1 to make the housing 1 and the fixed bracket 6 rotate against friction.

[0088] Furthermore, to prevent the connecting screw 71 and the limiting connecting nut 74 from loosening during prolonged use, a limiting hole 182 can be provided at one end of the first connecting hole 181. The limiting hole 182 is coaxial with the first connecting hole 181, and the inner wall shape of the limiting hole 182 matches the outer shape of the limiting connecting nut 74, thereby allowing the limiting connecting nut 74 to be embedded in the limiting hole 182. The inner wall of the limiting hole 182 limits the rotation of the limiting connecting nut 74, thus preventing loosening. In this embodiment, the limiting connecting nut 74 can be selected as a non-loosening nut in the prior art.

[0089] To better lock the rotation between the housing 1 and the fixed bracket 6 and to precisely control the rotation angle, this embodiment also provides an angle adjustment structure, such as... Figure 15 and Figure 16 As shown, based on the above-mentioned angle adjustment structure, positioning ribs 183 and positioning grooves 62 that can be inserted and fitted are respectively provided on the two contact surfaces of the mounting part 18 and the connecting ear plate 61.

[0090] Specifically, on the side surface of the mounting portion 18 facing the connecting ear plate 61, a plurality of positioning ribs 183 are radially spaced along the circumference of the first connecting hole 181, with the center of the first connecting hole 181 as the center. Correspondingly, on the side surface of the connecting ear plate 61 facing the mounting portion 18, a plurality of positioning grooves 62 are provided along the circumference of the second connecting hole 611. The plurality of positioning ribs 183 correspond one-to-one with the plurality of positioning grooves 62, and each positioning rib 183 can be inserted into a positioning groove 62. This arrangement ensures that the lamp structure will only rotate when subjected to a certain force, avoiding rotation of the lamp structure due to accidental contact. When the housing 1 and the fixed bracket 6 rotate relative to each other, the positioning ribs 183 are inserted into different positioning grooves 62 to achieve locking and fixing at the next angle.

[0091] In this embodiment, the positioning ribs 183 and positioning grooves 62 adopt a resolution of 360° / 6 = 60°, that is, a total of 6 sets of positioning ribs 183 and positioning grooves 62 are designed, so the minimum adjustable angle is 60°. It is understood that in other embodiments, other resolutions can be designed according to actual needs, and this embodiment does not limit this.

[0092] Optionally, continue to refer to Figure 11 The lighting fixture structure also includes a ground plug 8. The fixing bracket 6 is fixedly connected to the ground plug 8, and the lighting fixture structure can be positioned and fixed on the ground through the ground plug 8.

[0093] Example 4

[0094] This embodiment provides a lamp structure that is basically the same as the lamp structure provided in Embodiment 3, such as... Figure 17 and Figure 18 As shown, the difference between this embodiment and Embodiment 3 lies in the specific structure of the angle adjustment structure.

[0095] In this embodiment, an angle adjustment structure includes a pair of damping shafts 75 and a fixing screw 76. (Refer to...) Figure 17 One end of the mounting part 18 is provided with a mounting hole 184, and one end of the damping shaft 75 is interference-fitted with the mounting hole 184, thereby achieving a reliable connection between the damping shaft 75 and the mounting part 18. The other end of the damping shaft 75 is provided with a limiting plane 751, and a limiting elongated hole 63 is provided on the connecting ear plate 61. The other end of the damping shaft 75 can be inserted into the limiting elongated hole 63. The limiting elongated hole 63 is an oblong hole, and the radial cross section of the other end of the damping shaft 75 is adapted to the limiting elongated hole 63. This arrangement allows the damping shaft 75 to drive the fixed bracket 6 to rotate and prevents the damping shaft 75 from loosening from the fixed bracket 6. The fixing screw 76 is screwed to the end of the damping shaft 75 from the side of the connecting ear plate 61 away from the mounting part 18, thereby ensuring a reliable connection between the fixed bracket 6 and the damping shaft 75.

[0096] This embodiment also provides another angle adjustment structure, such as Figure 18 As shown, damping shafts 75 are provided on both sides of the mounting part 18. This ensures that the two connecting lugs 61 of the fixed bracket 6 are balanced, making it easier for the user to adjust the angle when rotating the housing 1 and improving user satisfaction.
