[0032] On the basis of the clamping connection between the inner shell 210 and the outer shell 100, the insertion portion 310 of the elastic mounting clip 300 passes through the outer shell 100 and is connected to the inner shell 210, and the mounting portion 320 of the elastic mounting clip 300 is located on the outside of the outer shell 100. The elastic mounting clip 300 can not only install the downlight on the ceiling, but also limit the position of the inner shell 210 relative to the outer shell 100, thereby further fixing the inner shell 210 and the outer shell 100, reducing the risk of the light-emitting module 200 falling relative to the outer shell 100, and no additional parts are required.

[0033] In the embodiment, the inner shell 210 is provided with a plug hole 212, the hole wall of the plug hole 212 is provided with a first hook 213, the insertion portion 310 is provided with a first hook hole 311, the insertion portion 310 is inserted in the plug hole 212, and the first hook 213 is engaged with the first hook hole 311. The insertion portion 310 is inserted in the plug hole 212, and the insertion portion 310 is engaged with the first hook 213 through the first hook hole 311, so that the assembly connection between the insertion portion 310 of the elastic mounting clip 300 and the inner shell 210 is relatively firm, and the insertion portion 310 of the elastic mounting clip 300 is not easy to fall off relative to the inner shell 210, and then the assembly of the inner shell 210 and the outer shell 100 is more firm and not easy to fall off through the elastic mounting clip 300.

[0034] It should be understood that when the downlight is not installed on the ceiling, the first clamp hole 311 and the first clamp hook 213 may have a certain assembly gap or may be tightly fitted. When the downlight is installed on the ceiling, the mounting portion 320 of the elastic mounting clip 300 is fixed to the ceiling, and the housing 100 and the light-emitting module 200 will have a tendency to fall relative to the elastic mounting clip 300 under the action of gravity. At this time, the insertion portion 310 applies an upward supporting force to the first clamp hook 213 through the first clamp hole 311, that is, the elastic mounting clip 300 directly applies a supporting force to the inner housing 210, and the inner housing applies a supporting force to the outer housing 100, so that the inner housing 210 will not fall off relative to the outer housing 100.

[0035] It is conceivable that in other embodiments, the first hook 213 may be provided on the insertion portion 310 , and the first hook hole 311 may be provided on the hole wall of the plug hole 212 . Those skilled in the art may make specific selections according to actual needs.

[0036] In the embodiment, the bottom wall 2121 of the plug hole 212 is tilted and used to guide the first clamping hole 311 to be clamped to the first clamping hook 213. Since the bottom wall 2121 of the plug hole 212 is tilted, when the insertion portion 310 is inserted into the plug hole 212, when the end of the insertion portion 310 contacts the bottom wall 2121 of the plug hole 212, the bottom wall 2121 of the plug hole 212 will guide the insertion portion 310 to slide a little, further increasing the clamping range between the first clamping hook 213 and the first clamping hole 311, and reducing the risk of the first clamping hook 213 and the first clamping hole 311 not being properly clamped.

[0037] In the embodiment, the outer wall of the inner shell 210 is provided with a clearance hole 214, and the clearance hole 214 is connected to the plug hole 212. The clearance hole 214 is provided to facilitate the production of the first hook 213 in the plug hole 212 by mold forming, thereby reducing the difficulty of producing the first hook 213 and improving the processability of the inner shell 210.

[0038] Specifically, after the outer shell 100 and the light emitting module 200 are assembled, the outer shell 100 covers the clearance hole 214 of the inner shell 210 .

[0039] In the embodiment, a guiding slope 2131 is provided on one side of the first hook 213 near the opening of the plug hole 212. The guiding slope 2131 is provided, and when the insertion portion 310 of the elastic mounting clip 300 is inserted into the plug hole 212, the guiding slope 2131 can guide the insertion portion 310 to slide and adjust the position, so that the insertion portion 310 can be smoothly inserted into the specified depth of the plug hole 212, so that the insertion portion 310 of the elastic mounting clip 300 can be inserted into the plug hole 212 more smoothly.

The spiral elastic part 330 is located in the recess 120, which can make the structure of the downlight more compact; the insertion part 310 is passed through the housing 100 and connected to the inner housing 210 through the mounting through hole 130, and the size of the spiral elastic part 330 is larger than the size of the mounting through hole 130, so that the spiral elastic part 330 will not be completely embedded in the mounting through hole 130, which is conducive to keeping the spiral elastic part 330 and the mounting part 320 of the elastic mounting clip 300 located outside the housing 100.

[0043] It is conceivable that the insertion part 310 can also be connected to the inner shell 210 through other structures to limit the position of the inner shell 210 relative to the outer shell 100. For example, the insertion part 310 and the inner shell 210 are riveted or bonded, etc., and technicians in this field can make specific choices based on actual needs.
