[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figures 1 to 5 This utility model discloses a detachable downlight, comprising a lamp holder 100, a light-emitting component 200, a light-emitting cover 300, at least two elastic locking members 400, and a pull handle 500. The lamp holder 100 has a receiving groove 101; the light-emitting component 200 is disposed in the lamp holder 100 and located within the receiving groove 101, with the light-emitting side of the light-emitting component 200 facing the opening of the receiving groove 101; the light-emitting cover 300 is detachably disposed in the lamp holder 100 and covers the opening of the receiving groove 101, and the light-emitting cover 300 has a light-emitting channel 301, the light inlet of the light-emitting channel 301 being opposite to the light-emitting component 200; at least two elastic locking members 400 are arranged around the outer periphery of the lamp holder 100; the pull handle 500 is disposed in the lamp holder 100 and located within the receiving groove 101, and the pull handle 500 is offset from the light inlet of the light-emitting cover 300.

[0033] The lamp holder 100 is snapped onto the ceiling by the elastic clip 400. Under normal conditions, the pull handle 500 is offset from the light inlet of the light emitter 300, so that the pull handle 500 does not interfere with the normal light output of the downlight. When the downlight needs to be disassembled, the user can first remove the light emitter 300 to expose the receiving groove 101. Then, the user can grasp the pull handle 500 in the receiving groove 101 to easily pull down the lamp holder 100, so that the downlight can be pulled down and disassembled relatively easily and the disassembly process is more stable.

[0034] In the embodiments, reference is made to Figure 3 and Figure 5The light emitter 300 has a conical plate 310, the inner side of which defines a light emission channel 301. A handle 500 is pivotally connected to the lamp holder 100 and overlaps the outer side of the conical plate 310. By overlapping the handle 500 with the outer side of the conical plate 310, the handle 500 can be offset from the light emission channel 301, preventing the light emitted from the light emission channel 301 from being blocked by the handle 500, resulting in better light emission performance.

[0035] In the embodiments, reference is made to Figure 3 The central axis of the light-emitting channel 301 is set in the vertical direction, and the pull handle 500 is rotatably connected to the lamp holder 100 with its rotation axis set in the front-back direction. The pull handle 500 can rotate relative to the lamp holder 100. After the user removes the light-emitting cover 300, the angle of the pull handle 500 can be adjusted to facilitate pulling down and removing the downlight, making it relatively convenient to use.

[0036] In the embodiments, reference is made to Figure 5 The pull handle 500 includes an arc-shaped rod 510 and two connecting rods 520. The two connecting rods 520 are arranged in the front-to-back direction and are respectively connected to the two ends of the arc-shaped rod 510. The connecting rods 520 are pivotally connected to the lamp holder 100, and the two connecting rods 520 are located on opposite sides of the conical plate 310. The user can hold the arc-shaped rod 510 to pull the lamp holder 100. The pull handle 500 has an arc-shaped rod 510, which can be rotated to a position that avoids the light emission channel 301 to accommodate the installation of the light emission cover 300. When it is necessary to disassemble the downlight, the arc-shaped rod 510 can be rotated to a suitable position to provide sufficient space for the user to firmly grasp the arc-shaped rod 510 by hand.

[0037] In the embodiments, reference is made to Figure 3 The radius of the arc rod 510 is greater than the radius of the end of the conical plate 310 near the light-emitting component 200, so that the arc rod 510 can be stably rotated to a position overlapping the outside of the conical plate 310, and the arc rod 510 will not be opposite the light inlet of the light-emitting channel 301, resulting in better stability.

[0038] It is conceivable that the handle 500 can also have other shapes, such as the handle 500 including a U-shaped rod and two connecting rods 520, with the two connecting rods 520 respectively connected to the two ends of the U-shaped rod; or the handle 500 can be a straight rod strip set on the lamp holder 100.

[0039] It is conceivable that in some other embodiments, the pull handle 500 may also be fixedly connected to the lamp holder 100, and those skilled in the art may choose according to actual needs.

[0040] In the embodiments, reference is made to Figure 3The light emitter 300 is provided with a first elastic hook 320, and the groove wall of the receiving groove 101 is provided with a first slot 102. The first elastic hook 320 engages with the first slot 102. The light emitter 300 is engaged with the first slot 102 of the receiving groove 101 by the first elastic hook 320, thus achieving the installation of the two. When the light emitter 300 is subjected to a certain pulling force, the first elastic hook 320 can elastically deform, causing the first elastic hook 320 to disengage from the first slot 102, thereby removing the light emitter 300. Both installation and disassembly are relatively convenient.

[0041] Optionally, in other embodiments, a first slot 102 may be provided in the light-emitting cover 300, and a first elastic hook 320 may be provided in the groove wall of the receiving groove 101.

[0042] It is conceivable that in other embodiments, the light emitter 300 can also be detachably connected to the lamp holder 100 in other ways. For example, the light emitter 300 is provided with a stud portion, the lamp holder 100 is provided with a threaded hole, and the light emitter 300 is directly threaded to the lamp holder 100 to achieve a detachable connection between the two; or the light emitter 300 can be detachably installed to the lamp holder 100 by magnetic attraction.

[0043] In the embodiments, reference is made to Figure 3 and Figure 5 The lamp holder 100 includes a heat sink 110, a light guide 120, a swing cover 130, and a mounting cylinder 140. The light-emitting component 200 is mounted on the heat sink 110. The light guide 120 is fixedly mounted on the heat sink 110 and arranged around the light-emitting component 200. The swing cover 130 is swayably connected to the light guide 120, with its rotation axis set along the front-to-back direction. The swing cover 130 is inserted into the mounting cylinder 140, which is rotatable relative to the swing cover 130, and its rotation axis is set along the vertical direction. An elastic locking member 400 is mounted on the outer periphery of the mounting cylinder 140. The lamp holder 100 described above satisfies common light emission angle adjustment functions and has good versatility.

[0044] In the embodiments, reference is made to Figure 1 and Figure 5 The lamp holder 100 also includes a cover 150 and a threaded fastener. The heat sink 110 has a through hole, and the light guide 120 has a threaded hole. The threaded fastener passes through the through hole and is threaded into the threaded hole to lock the light guide 120 to the heat sink 110. The cover 150 is snapped onto the heat sink 110 and covers the through hole. By providing the cover 150, the threaded fastener and the through hole are covered, so that the connection structure of the lamp holder 100 is not exposed, making it safer to use and relatively aesthetically pleasing.

[0045] Specifically, the cover 150 is provided with a second elastic hook, and the heat sink 110 is provided with a second slot, with the second elastic hook engaging with the second slot. The threaded fastener is a screw. Optionally, in some other embodiments, the cover 150 may be provided with a second slot, and the heat sink 110 may be provided with a second elastic hook; the threaded fastener may also be a bolt and nut pair.

[0046] In the embodiments, reference is made to Figure 5 The light guide cover 120 is provided with a rotating shaft 121, and the swing cover 130 is provided with a shaft hole 131. The rotating shaft 121 is rotatably connected to the shaft hole 131. The rotating shaft 121 is provided with a rotating connection hole 122 along the central axis direction, and the end of the pull handle 500 is rotatably inserted into the rotating connection hole 122. The above-mentioned rotating connection structure has a relatively compact layout and high structural strength.

[0047] In the embodiments, reference is made to Figure 1 and Figure 3 The inner wall of the mounting cylinder 140 is provided with multiple stop slots 141 arranged around its rotation axis. The swing cover 130 is provided with a flexible stop block 132, which abuts against the stop slots 141. When the mounting cylinder 140 rotates relative to the swing cover 130, the flexible stop block 132 can switch to the adjacent stop slot 141. By setting the stop slots 141 and the flexible stop block 132, the mounting cylinder 140 has a certain stop feel and a self-locking function when rotating relative to the swing cover 130, which makes it easy for the mounting cylinder 140 to maintain its current position relative to the swing cover 130, so that the mounting cylinder 140 cannot rotate freely relative to the swing cover 130, and the positional stability is good.

[0048] Specifically, heat dissipation fins are provided on the outer side of the heat dissipation shell 110, which gives the heat dissipation shell 110 a better heat dissipation effect.

[0049] Specifically, the pull handle 500 is a metal rod that can be rotated and snapped into the rotating connection hole 122 of the lamp holder 100 after a certain degree of elastic deformation.

[0050] Specifically, the light-emitting component 200 includes a lamp panel 210 and a lens 220. The lamp panel 210 is provided with a lamp core, and the lens 220 is located on the light-emitting side of the lamp core.

[0051] Specifically, there are two flexible clips 400 on the outside of the lamp holder 100. The flexible clips 400 are the existing ceiling mounting structure for downlights, which will not be described in detail here.

[0052] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
