[0031] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0032] See also Figure 1-Figure 4 , shows a conveniently disassembled downlight according to a preferred embodiment of the utility model, comprising:

[0033] Lamp body 1;

[0034] The spring sheet 2 is installed, and the spring sheet 2 extends transversely. The spring sheet 2 is provided with a first connection portion 21, a second connection portion 22, and a third connection portion 23 arranged in sequence along the length direction thereof. At least part of the first connection portion 21, the second connection portion 22, and the third connection portion 23 are exposed outside the lamp body 1. One end of the first connection portion 21 away from the second connection portion 22 is connected to the lamp body 1. The first connection portion 21 is arranged horizontally, and the second connection portion 22 is arranged downwardly inclined relative to the first connection portion 21. The angle between the second connection portion 22 and the first connection portion 21 is A, and 175°≤A≤165°. The third connection portion 23 is arranged downwardly inclined relative to the second connection portion 22. The angle between the third connection portion 23 and the first connection portion 21 is B, and 150°≤B≤140°.

[0035] When the mounting spring piece 2 is connected to the hole wall of the metal mounting device, the mounting spring piece 2 is bent downward, and at least a portion of at least the third connecting portion 23 is used to elastically abut against the hole wall of the metal mounting device to fix the lamp body 1 on the metal mounting device.

[0036] The downlight of the utility model can be installed on the metal mounting device by holding the lamp body 1 and pushing the lamp body 1 toward the metal mounting device, so that the mounting spring piece 2 is bent downward by the thrust of the hole wall of the metal mounting device, and at least a part of at least the third connecting portion 23 is elastically abutted against the hole wall of the metal mounting device, so that the lamp body 1 can be installed on the metal mounting device. When disassembling, the lamp body 1 can be detached from the metal mounting device by rotating the lamp body 1 counterclockwise and pulling the lamp body 1 downward, which is convenient for disassembly and assembly, and has high disassembly and assembly efficiency. The second connecting portion 22 is arranged to be tilted downward relative to the first connecting portion 21, and the angle between the two is 16 The third connecting portion 23 is inclined downward relative to the second connecting portion 22 and the angle between the third connecting portion 23 and the first connecting portion 21 is in the range of 140°-150°, so that the mounting spring piece 2 has a secondary bending structure. Such a structural setting can make the mounting spring piece 2 have better tension and toughness. The mounting spring piece 2 with better tension and toughness can reliably abut against the hole wall of the metal mounting device, thereby increasing the connection reliability between the lamp body 1 and the metal mounting device, making it difficult for the lamp body 1 to fall off the metal mounting device, and having higher structural reliability.

[0037] Among them, it can be understood that the connection between the mounting spring clip 2 and the hole wall of the metal mounting device is a mechanical connection, which is only used to fix the lamp body 1 on the metal mounting device. In addition, before the lamp body 1 is installed on the metal mounting device, it is necessary to first connect the wiring structure on the lamp body 1 and the power wiring structure built into the metal mounting device to ensure that the lamp body 1 can be powered, and then connect the mounting spring clip 2 and the hole wall of the metal mounting device together.

[0038] In one embodiment, A=170°, B=145°, that is, the angle between the second connecting portion 22 and the first connecting portion 21 is 170°, and the angle between the third connecting portion 23 and the first connecting portion 21 is 145°. The second connecting portion 22 and the third connecting portion 23 at the corresponding angles can make the mounting spring clip 2 have greater tension and better toughness, and can improve the connection reliability between the mounting spring clip 2 and the hole wall of the metal mounting device, thereby making the lamp body 1 less likely to fall off the metal mounting device.

[0039] In one embodiment, A=175°, B=150°, that is, the angle between the second connecting portion 22 and the first connecting portion 21 is 175°, and the angle between the third connecting portion 23 and the first connecting portion 21 is 150°. The second connecting portion 22 and the third connecting portion 23 at the corresponding angles can make the mounting spring clip 2 have moderate tension and moderate toughness, which can improve the connection reliability between the mounting spring clip 2 and the hole wall of the metal mounting device, thereby preventing the lamp body 1 from falling off the metal mounting device.

[0040] In one embodiment, A=165°, B=140°, that is, the angle between the second connecting portion 22 and the first connecting portion 21 is 165°, and the angle between the third connecting portion 23 and the first connecting portion 21 is 140°. The second connecting portion 22 and the third connecting portion 23 at the corresponding angles can make the mounting spring clip 2 have moderate tension and moderate toughness, and can improve the connection reliability between the mounting spring clip 2 and the hole wall of the metal mounting device, so that the lamp body 1 is not easy to fall off the metal mounting device.

[0041] In one embodiment, a first arc portion 24 is provided at the outer edge of the corner of the third connecting portion 23, that is, the corner of the third connecting portion 23 is transitionally processed by the first arc portion 24, so that the outer edge of the corner of the third connecting portion 23 is smoother, avoiding the problem of jamming during disassembly and assembly, and making disassembly and assembly smoother.

[0042] In one embodiment, a second arc portion 25 is provided at the outer edge of the corner between the third connection portion 23 and the second connection portion 22, that is, the corner between the third connection portion 23 and the second connection portion 22 is transitionally processed by the second arc portion 25, so that the outer edge of the corner between the third connection portion 23 and the second connection portion 22 is more circular, thereby avoiding the problem of jamming during disassembly and assembly, and making disassembly and assembly smoother.

[0043] In one embodiment, the number of mounting spring clips 2 is at least two, and at least two mounting spring clips 2 are arranged at intervals around the vertical center line of the lamp body 1, which can increase the connection stability between the lamp body 1 and the metal mounting device and improve the structural reliability.

[0044] In one embodiment, the number of mounting spring clips 2 is three, and the three mounting spring clips 2 are arranged at equal intervals around the vertical center line of the lamp body 1 so that the three mounting spring clips 2 form a triangular structure, which can further increase the connection stability between the lamp body 1 and the metal mounting device, and the structural reliability is higher.

[0045] In one embodiment, the number of mounting spring clips 2 can be set to one. In this case, the mounting spring clips 2 are arranged around the vertical center line of the lamp body 1 to increase the contact area between the mounting spring clips 2 and the hole wall of the metal mounting device, thereby increasing the connection reliability between the lamp body 1 and the metal mounting device.

[0046] In one embodiment, the lamp body 1 comprises:

[0047] A lamp body 11, a positioning groove 111 is provided on the top surface of the lamp body 11;

[0048] A power source body 12, which is disposed on the top surface of the lamp body 11 through a fastener 3 to fix the power source body 12 and the lamp body 11 together;

[0049] The first connection part 21 cooperates with the positioning groove 111, and the first connection part 21 has a connection hole 211, which is connected with the positioning groove 111, and the connection hole 211 is for the rod of the fastener 3 to pass through, and at least part of the first connection part 21 is sandwiched between the lamp body 11 and the power supply body 12. In this way, the first connection part 21 and the positioning groove 111 can be used to cooperate to realize the positioning of the installation spring piece 2, ensuring that the installation spring piece 2 is set at the set position, and then the connection hole 211 and the rod of the fastener 3 are used to limit the installation elasticity, limiting the movement of the installation spring piece 2 along its length direction, and at the same time, through the clamping effect of the lamp body 11 and the power supply body 12, the installation spring piece 2 is reliably fixed on the lamp body 1, so that the installation spring piece 2 will not shake left and right, up and down, and ensure that the installation spring piece 2 can be reliably connected to the hole wall of the metal installation device, and the structural reliability is higher.

[0050] It can be understood that the lamp body 11 is a combined structure including a lamp source and a lampshade, and the power supply body 12 is a combined structure including a power supply housing and a power supply.

[0051] In one embodiment, the positioning groove 111 includes a first positioning section 1111 and a second positioning section 1112. The first positioning section 1111 penetrates the lamp body 11 both inside and outside, and penetrates the top wall of the lamp body 11. The first positioning section 1111 is connected to the connecting hole 211. The first positioning section 1111 cooperates with the first connecting portion 21 to limit the left and right movement of the first connecting portion 21 along the lamp body 11. The second positioning section 1112 is closer to the vertical center line of the lamp body 11 than the first positioning section 1111. The second positioning section 1112 is connected to the first positioning section 1111. The second positioning section 1112 cooperates with the first connecting portion 21 to limit the first connecting portion 21 from moving in a direction close to the vertical center line of the lamp body 11 and moving upward. In this way, the first connecting portion 21 is limited in different directions by the first positioning section 1111 and the second positioning section 1112 respectively, ensuring that the installation spring piece 2 is reliably installed in the set position.

[0052] In one embodiment, the fastener 3 is located inside the lamp body 1 to hide the fastener 3 , which plays a certain anti-rust role and also helps to improve the appearance of the lamp body 1 .

[0053] In one embodiment, a protrusion 212 is provided on the top surface of the first connecting portion 21, and the protrusion 212 extends along the length direction of the mounting spring piece 2. The provision of the protrusion 212 can enhance the structural strength of the first connecting portion 21, thereby enhancing the structural strength of the mounting spring piece 2, so that the mounting spring piece 2 can be reliably abutted against the hole wall of the metal mounting device.

[0054] In one embodiment, the mounting spring piece 2 is a structure made of a plastic material, or may be a structure made of a thin-walled metal material.

[0055] In one embodiment, the length of the mounting spring clip 2 exposed from the lamp body 1 is 50 mm, and the exposed part 17 mm is bent downward by 170° to form a second connecting portion 22, and the exposed part 21 mm is bent again by 25° to form a third connecting portion 23. The mounting spring clip 2 with an exposed length of 50 mm can effectively be compatible with 4-inch, 5-inch, and 6-inch metal mounting devices on the market, and has better compatibility.
