[0037] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0038] With reference to Figure 1 and Figure 2 , the lighting device according to the embodiments of the present application comprises a housing 100, a lens 200, a light source 300, a rotating cylinder 400 and a connecting rod 500. The housing 100 is provided with a light outlet end 110 on one side in a first direction; the lens 200 is movably arranged in the housing 100 in the first direction; the light source 300 is fixed in the housing 100 and located on the side of the lens 200 away from the light outlet end 110; the rotating cylinder 400 is rotatably arranged in the housing 100, with reference to Figure 6 , the rotating cylinder 400 is formed with a threaded groove 410, the axis of the threaded groove 410 being in the first direction; the connecting rod 500 movably penetrates the rotating cylinder 400 in the first direction, the connecting rod 500 is provided with a protrusion 510, the protrusion 510 movably penetrates the threaded groove 410 in the threaded groove 410, and the connecting rod 500 is connected with the lens 200.

[0039] It can be understood that the light source 300 can emit light, the light passes through the lens 200 and is irradiated out through the light outlet end 110 of the housing 100. When the irradiation range of the light needs to be adjusted, the rotating cylinder 400 is rotated, the rotating cylinder 400 rotates relative to the connecting rod 500, the protrusion 510 on the connecting rod 500 can move in the threaded groove 410 on the rotating cylinder 400, since the connecting rod 500 is movable in the first direction but fixed in the circumferential direction, when the protrusion 510 moves in the threaded groove 410, the connecting rod 500 can move in the first direction relative to the rotating cylinder 400, the connecting rod 500 drives the lens 200 to move in the first direction, the distance between the lens 200 and the light source 300 changes, and thus the irradiation range of the light emitted through the lens 200 changes.

[0040] Specifically, with reference to Figure 4The side of the lens 200 away from the light source 300 has a light-reflecting curved surface and a light-transmitting curved surface. The light emitted by the light source 300 can pass through the lens 200 and be emitted from the light-transmitting curved surface. The light-transmitting curved surface can disperse the light, and part of the light is emitted from the light-emitting end 110 of the shell 100, and part of the light is reflected to the light-reflecting curved surface. The light-reflecting curved surface reflects and converges the light again so that the light is emitted from the light-emitting end 110 of the shell 100. Thus, when the distance between the lens 200 and the light source 300 is adjusted by rotating the rotating cylinder 400, the light irradiation range can be adjusted. Further, the lens 200 can include a light-reflecting cup.

[0041] Specifically, the lighting device of the present application is a spotlight.

[0043] It can be understood that the lens 200 is clamped by the limiting structure 600, and the lens 200 can be conveniently disassembled. The connecting rod 500 is connected with the lens 200 through the limiting structure 600, which can facilitate the connection of the connecting rod 500 and the lens 200. When the connecting rod 500 moves along the first direction, the limiting structure 600 can be driven to move along the first direction to drive the lens 200 to move along the first direction.

[0044] With reference to Figure 4 , according to some embodiments of the present application, the limiting structure 600 includes a first clamping block 610 and a second clamping block 620, the first clamping block 610 and the second clamping block 620 are detachably connected, a clamping groove 630 is formed between the first clamping block 610 and the second clamping block 620, the edge of the lens 200 is clamped in the clamping groove 630, and the connecting rod 500 is connected with the second clamping block 620.

[0045] It can be understood that when the first clamping block 610 and the second clamping block 620 are connected together, the clamping groove 630 is formed between the first clamping block 610 and the second clamping block 620, and the edge of the lens 200 is clamped in the clamping groove 630, thereby fixing the lens 200. When the first clamping block 610 and the second clamping block 620 are disengaged, the lens 200 can be easily separated from the clamping groove 630, or placed between the first clamping block 610 and the second clamping block 620, so as to facilitate the disassembly of the lens 200 relative to the limiting structure 600.

[0046] It can be understood that the first clamping block 610 and the second clamping block 620 clamp the edge of the lens 200, which does not affect the light-transmitting effect of the lens 200.

[0047] It can be understood that the connecting rod 500 is connected with the second clamping block 620, and the connecting rod 500 drives the first clamping block 610 and the lens 200 to move through the second clamping block 620.

[0048] Specifically, the lens 200 is a rotary body, the edge of the lens 200 is annular, the first clamping block 610 and the second clamping block 620 are also rotary bodies, and the clamping groove 630 formed between the first clamping block 610 and the second clamping block 620 is annular, so that the connection tightness between the limiting structure 600 and the lens 200 can be improved.
