Specifically, in this embodiment, the light emitting device includes: the LED module comprises a PCB 41 arranged at the bottom of the accommodating groove 31, an LED lamp 42 electrically connected with the PCB 41, a heat dissipation patch 43 attached to the LED lamp 42, a support 44 and a reflector 45. The LED lamp 42 is arranged on the support piece 44, and the LED lamp 42 is fixedly installed. The middle part of the reflector 45 is provided with a rectangular through hole 451, two opposite edges of the through hole 451 are respectively provided with an L-shaped folded edge 452, and the support piece 44 is embedded into the through hole 451 and clamped between the two L-shaped folded edges 452 to stably fix the support piece 44. Further, the other two edges of the through hole 451 are respectively provided with a wing 453. Preferably, the L-shaped flap 452 and the wing 453 are integrally formed with the reflector 45.

The inner wall of the lamp body 30 is provided with an annular clamping groove 32 and a plurality of sliding grooves 33 which are coaxially arranged with the accommodating groove 31 and are uniformly distributed, and the sliding grooves 33 axially extend along the inner wall of the lamp body 30. In this embodiment, the sliding grooves 33 are vertically communicated with the ring-shaped clamping grooves 32, and each sliding groove 33 is formed between two bosses which are arranged on the inner wall of the lamp body 30 at intervals. The movable ring 50 includes a plurality of guide posts 51 protruding from the outer wall and an elastic member 52 correspondingly connecting the guide posts, the guide posts 51 are correspondingly disposed in the sliding slot 33, the guide posts 51 can slide in the sliding slot 33 along the axial direction of the lamp body 30, and the elastic member 52 is used for providing a reverse resistance different from the sliding direction of the guide posts 51. In this embodiment, the number of the sliding grooves 33 and the number of the guide posts 51 are three; the number and distribution of the chutes 33 may be set according to practical applications, and are not limited to three and uniform distribution.

In this embodiment, the elastic member 52 is a spring, the inner wall of the lamp body 30 is provided with a positioning hole 34, the positioning hole 34 is disposed toward the sliding slot 33, a first end of the spring is embedded in the guiding post 51, and a second end of the spring is inserted into the positioning hole 34, so as to improve the stability of the spring during the compression and extension processes. In other embodiments, the elastic member 52 may be an elastic sheet.

The lens 60 is fixedly disposed in the movable ring 50, so that the lens 60 moves synchronously with the movable ring 50 during the reciprocating movement of the movable ring 50 along the central axis of the accommodating groove 31. In the way of how to fixedly connect the lens 60 and the movable ring 50, in this embodiment, the inner wall of the movable ring 50 is provided with a plurality of protrusions 53, the edge of the lens 60 is provided with a plurality of limiting grooves 61, and the protrusions 53 are clamped in the limiting grooves 61, so as to fix the lens 60 and prevent the lens 60 from rotating and falling off from the movable ring 50.
