[0037] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0038] like Figures 1 to 5As shown, a lighting fixture 10 with an adjustable light output aperture of an embodiment includes a shell 100, a light source module 200, a lens 300 and a rotating baffle assembly 400, the inner wall of the shell 100 is provided with an embedding groove 110, the lens 300 is installed in the embedding groove 110, the shell 100 is provided with a light-transmitting port 120a, the shell 100 is also provided with a moving channel 120b, the inner wall of the shell 100 is provided with a plurality of elastic clamping columns 130 arranged at intervals, the light source module 200 includes a heat dissipation shell 210 and a light source component 220, the light source component 220 is installed at one end of the heat dissipation shell 210, the lens 300 is located on the light output side of the light source component 220, the outer peripheral wall of the heat dissipation shell 210 is provided with a clamping groove 211, the clamping groove 211 is used for the heat dissipation shell 210 to be clamped with the elastic clamping column 130 after moving along the extension direction of the moving channel 120b.

[0039] Further, the rotating baffle assembly 400 includes a fixed seat 410, a blade drive disk 420 and a plurality of movable blades 430, the fixed seat 410 is connected to the outer peripheral wall of the light-transmitting port 120a, the plurality of movable blades 430 are all mounted on the fixed seat 410, the plurality of movable blades 430 are all slidably connected to the blade drive disk 420, the blade drive disk 420 is covered on the fixed seat 410, and the blade drive disk 420 is rotatably connected to the fixed seat 410, so that the plurality of movable blades 430 jointly form a light outlet 431 with an adjustable aperture size, and the light outlet 431 is connected to the light-transmitting port 120a. In another embodiment, the rotating baffle assembly is an aperture.

[0040] In this embodiment, the lens 300 is installed in the embedding groove 110 and is located on the light emitting side of the light source component 220. A plurality of elastic snap-in columns 130 are convexly provided at intervals inside the shell 100. A snap-in groove 211 is provided on the outer wall of the heat dissipation shell 210. The light source component 220 is installed at one end of the heat dissipation shell 210. Under the action of external force, the elastic snap-in column 130 is deformed so that the heat dissipation shell 210 can move along the extension direction of the moving channel 120b. When the external force disappears, the elastic snap-in column 130 is snap-fitted with the snap-in groove 211 to fix the heat dissipation shell 210 to the shell 100.

In this way, the adjustment accuracy of the light outlet diameter can be improved through secondary adjustment.

[0041] In the above-mentioned lighting fixture 10 with adjustable light-emitting aperture, the inner wall of the housing 100 is provided with a plurality of elastic snap-in columns 130 arranged at intervals, and the outer peripheral wall of the heat dissipation shell 210 is provided with a snap-in groove 211, so that the heat dissipation shell 210 is snap-fitted with the housing 100.

Furthermore, the plurality of movable blades 430 are all slidably connected to the blade drive disk 420, and the blade drive disk 420 is rotatably connected to the fixed seat 410, so that the plurality of movable blades 430 can slide relative to the blade drive disk 420, thereby adjusting the aperture size of the light-emitting aperture 431. In this way, the light outlet 431 can be adjusted by adjusting the distance between the light source 220 and the lens 300 and driving the movable blade 430 to slide, so that the aperture size of the light outlet 431 can be adjusted more accurately and the structure is more compact.

[0042] In one embodiment, the distance between two adjacent elastic clamping posts 130 is 10 mm-15 mm. In this embodiment, the distance between two adjacent elastic clamping posts 130 is 10 mm, that is, the distance between the light source 220 and the lens 300 is adjusted by the distance between the multiple elastic clamping posts 130.

[0043] In one embodiment, each of the elastic clamping columns 130 is a silicone clamping column. In this embodiment, the elastic clamping column 130 is made of silicone material and is bonded to the inner wall of the housing 100. The silicone clamping column has a certain elastic deformation performance so that it can be elastically deformed under the action of external force. Of course, in other embodiments, the elastic clamping column 130 can also be made of elastic materials such as rubber or plastic.

[0044] like Figure 4 As shown, in one embodiment, the fixed seat 410 is provided with a plurality of mounting holes 411, and the blade driving disk 420 is provided with a plurality of sliding guide grooves 421.

It can be understood that the front lens barrel 500 is sleeved on the fixing seat 410 so that the front lens barrel 500 and the fixing seat 410 are fixed, and when the light of the light source 220 passes through the lens 300, the light-transmitting port 120a, and the light-emitting port 431 in sequence and enters the sleeve opening 510 of the front lens barrel 500, the front lens barrel 500 makes the emitted light more concentrated.

[0049] In one embodiment, each of the elastic clamping posts 130 is in a ring shape. In this embodiment, the clamping slot 211 is also in a ring shape, so that the clamping effect between the elastic clamping posts 130 and the clamping slot 211 is better.
