[0021] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0022] like Figures 1-6 The lamp shown is a downlight with replaceable lens, including a cylindrical body 1 and a cover 2. A lens 4 is provided on the cover 2. A first through hole 5 is provided in the center of the cover 2. A limiting ring 6 is provided inside the first through hole 5. A lens fixing ring seat 7 is provided in the first through hole 5. The lens fixing ring seat 7 is detachably connected to the limiting ring 6 by a rotating buckle structure. The lens 4 is detachably placed on the lens fixing ring seat 7. When the lens fixing ring seat 7 is connected to the limiting ring 6, the lens 4 is pressed between the limiting ring 6 and the lens fixing ring seat 7.

[0023] Based on the above structure, firstly, by setting a first through hole 5 in the center of the cover 2 and setting a limiting ring 6 inside the first through hole 5, and cooperating with the lens fixing ring 7 which is detachably connected to the limiting ring 6 using a rotating snap-fit ​​structure, the lens 4 can be quickly and conveniently replaced. When the lens 7 is damaged or the lighting effect needs to be adjusted, the user does not need to use complicated tools, but only needs to rotate the lens fixing ring 7 to remove it and complete the lens replacement. The operation is simple and convenient, greatly reducing the difficulty and cost of maintenance. Secondly, this structural design ensures that the lens 4 is pressed tightly between the limiting ring 6 and the lens fixing ring 7, ensuring the stability of the lens 4 installation and effectively preventing the lens 4 from loosening or shifting during use, thus ensuring the stability of the downlight lighting effect. In addition, the replaceable feature of the lens 4 allows the downlight to be adapted to lenses with different optical parameters, meeting the diverse lighting needs of users in different scenarios, improving the versatility and applicability of the downlight, and expanding the application range of the product.

[0024] See Figure 3 , Figure 6As shown, a limiting protrusion ring 21 is provided on the outer side of the lens 4, and a second through hole 22 is provided at the center of the lens fixing ring seat 7. A concave annular groove 23 is provided at the upper edge of the second through hole 22. The limiting protrusion ring 21 is placed in the concave annular groove 23. When the lens fixing ring seat 7 is connected to the limiting ring 6, the limiting protrusion ring 21 abuts against the limiting ring 6. The limiting protrusion ring 21 on the outer side of the lens 4 and the concave annular groove 23 at the upper edge of the second through hole 22 in the center of the lens fixing ring seat 7 enable the lens 4 to be accurately positioned during installation, preventing the lens 4 from shifting during use and ensuring the stability and consistency of the lighting effect. At the same time, when the lens fixing ring seat 7 is connected to the limiting ring 6, the limiting protrusion ring 21 abuts against the limiting ring 7, further enhancing the firmness of the lens installation and improving the reliability of the overall structure of the downlight.

[0025] Furthermore, a plurality of positioning flanges 31 are evenly distributed along the circumference within the concave annular groove 23, and a plurality of positioning grooves 32 that cooperate with the positioning flanges 31 are provided on the limiting protrusion ring 21. The cooperation between the positioning flanges 31 in the concave annular groove 23 and the positioning grooves 32 on the limiting protrusion ring 21 further enhances the positioning effect of the lens 4 on the lens fixing ring seat 7, prevents the lens 4 from rotating in the horizontal direction, and ensures that the lens 4 can maintain the correct installation angle in various usage environments, thereby ensuring accurate projection of lighting light and improving lighting quality.

[0026] See Figure 5 , Figure 6 As shown, the rotary buckle structure includes L-shaped buckles 41 evenly distributed around the upper end of the lens fixing ring seat 7. A slot 42 is formed between the L-shaped buckles 41 and the lens fixing ring seat 7. Several clearance grooves 43 corresponding to the L-shaped buckles 41 are evenly distributed around the circumference of the limiting ring 6. A snap-fit ​​block 44 is provided on one side of the clearance groove 43. The L-shaped buckles 41 can be placed in the clearance groove 43, and by rotating, the snap-fit ​​block 44 is snapped into the slot 42.

[0027] During installation, align the L-shaped buckle 41 of the lens fixing ring seat 7 with the clearance groove 43 of the limiting ring 6, insert the L-shaped buckle 41 into the clearance groove 43, and then rotate the lens fixing ring seat 7 clockwise or counterclockwise so that the locking block 44 is engaged in the locking slot 42 between the L-shaped buckle 41 and the lens fixing ring seat 7 to complete the connection; during disassembly, rotate the lens fixing ring seat 7 in the opposite direction so that the locking block 44 is disengaged from the locking slot 42, and the lens fixing ring seat 7 can be removed from the limiting ring 6.

[0028] Thus, the rotating buckle structure composed of L-shaped buckle 41, buckle slot 42, clearance groove 43 and buckle block 44 is simple in structure and easy to operate, and can quickly realize the connection and disassembly of lens fixing ring seat 7 and limiting ring 6; at the same time, the buckle connection method of this structure has good tightness, which can effectively prevent the lens fixing ring seat 6 from loosening during use, ensure the stable installation of the lens, and improve the reliability and safety of the downlight.

[0029] Furthermore, anti-slip textures 51 are provided on both the snap-fit ​​block 44 and the slot 42. The anti-slip textures 51 provided on the snap-fit ​​block and the slot 42 increase the friction between the two, further improving the firmness of the rotary snap-fit ​​structure connection, preventing the snap-fit ​​block 44 from sliding out of the slot 42 due to vibration or other factors during use, ensuring a reliable connection between the lens fixing ring seat 7 and the limiting ring 6, and ensuring the normal and stable operation of the downlight.

[0030] See Figure 1 As shown, decorative raised stripes 61 are evenly distributed along the circumference on the lower end face of the lens fixing ring seat 7. The decorative raised stripes on the lower end face of the lens fixing ring seat 7 can not only increase the aesthetics and uniqueness of the downlight, and enhance the visual effect and market competitiveness of the product, but also play a certain role in anti-slip, making it easier for users to grip and operate when installing or removing the lens fixing ring seat 7.

[0031] See Figures 3-4 As shown, a circuit board 71 is installed inside the cylindrical body 1, and the circuit board 71 is fixed to the cover 2 by a first snap-fit ​​structure 73. An LED bead 72 is installed at the lower end of the circuit board 71. The installation of the circuit board 71 inside the cylindrical body 1 and its fixation to the cover 2 by the first snap-fit ​​structure 73 makes the installation and removal of the circuit board 71 more convenient, facilitating maintenance and replacement. The LED bead 72 at the lower end of the circuit board 71 ensures the downlight's light-emitting function, and this structural design facilitates the cooperation between the LED bead 72 and the lens 4, achieving reasonable light projection. Simultaneously, the fixing method of the first snap-fit ​​structure 73 ensures the stability of the circuit board 71 inside the downlight, preventing the circuit board 71 from shaking during use and affecting the normal operation of the LED bead.

[0032] Furthermore, the cover 2 is fixed to the cylinder 1 by the second snap-fit ​​structure 81; the fixation of the cover 2 to the cylinder 1 by the second snap-fit ​​structure 81 makes the assembly and disassembly of the cover 2 and the cylinder 1 simple and quick, and facilitates the maintenance and replacement of internal components of the downlight (such as circuit board 71, lens 4, etc.); at the same time, the fixing method of the snap-fit ​​structure has good tightness, which can ensure the stability of the connection between the cover 2 and the cylinder 1, prevent the cover 2 from loosening or falling off during use, and improve the overall structural strength and reliability of the downlight.

[0033] In this invention, a battery compartment 91 is provided at the upper end of the cylindrical body 1. A battery 92 that can be electrically connected to the circuit board 71 is provided inside the battery compartment 91. A battery cover 93 is also provided on the battery compartment 91. The battery compartment 91 at the upper end of the cylindrical body 1, which houses the battery 92 that is electrically connected to the circuit board 71, enables the downlight to have independent power supply capability, eliminating the dependence on fixed power lines. It can be used in places without power sockets (such as temporary construction sites, outdoor camping, etc.), greatly expanding the application range of the downlight. The battery cover 93 on the battery compartment 91 facilitates the installation, replacement and maintenance of the battery 92, and also protects the battery from external factors such as dust and moisture, ensuring the normal service life and power supply stability of the battery.
