[0002] Adjustable illumination angle luminaires are a type of luminaire that breaks through the limitations of fixed light paths in traditional luminaires and can dynamically adjust the beam projection angle.

[0025] This application provides a beam angle adjustment structure. The beam angle adjustment structure includes an optical element, a light source element, a mounting element, and a telescopic adjustment assembly. At least one of the optical element and the light source element is rotatably disposed on the mounting element, and light is configured to be emitted through the light source element and at least partially incident into the optical element for redirection and emission. The telescopic adjustment assembly includes at least one guide element and at least one limiting element. The guide element is protrudingly connected to the side of the light source element near the mounting element or the side of the optical element near the mounting element. The limiting element is disposed on the mounting element, circumferentially surrounding the mounting element, and its two ends are adjacent to the two ends of the mounting element in a one-to-one correspondence. The guide element is slidably connected to the limiting element. Further, the optical element or the light source element is engaged with the mounting element.

[0026] The aforementioned beam angle adjustment structure allows at least one of the optical component and the light source component to be rolled onto the mounting component, enabling the optical component and / or the light source component to roll relative to the mounting component. This allows the light emitting surface of the optical component and / or the light emitting surface of the light source component to rotate 360 ​​degrees relative to the mounting component, thereby achieving 360-degree adjustment of the illumination angle of the beam angle adjustment structure. A guide component is protruding from the side of the optical component or the light source component near the mounting component. The guide component is slidably connected to a limiting component, which is circumferentially arranged around the mounting component. Both ends of the limiting component are adjacent to the two ends of the mounting component, meaning the limiting component is circumferentially arranged around the mounting component and extends towards both ends of the mounting component. This allows the optical component or the light source component to slide between the guide component and the limiting component relative to the two ends of the mounting component. In other words, based on the adjustable illumination angle, the beam angle is also adjustable, thereby improving illuminance uniformity and luminous efficiency.

[0027] To better understand the beam angle adjustment structure of this application, the following further explanation is provided: Please refer to the following: Figures 1 to 3 One embodiment of the beam angle adjustment structure 10 includes an optical element 100, a light source 200, a mounting member 300, and a telescopic adjustment assembly 400. At least one of the optical element 100 and the light source 200 is rotatably disposed on the mounting member 300, and light is configured to be emitted through the light source 200 and at least partially incident into the optical element 100 for redirection and emission. The telescopic adjustment assembly 400 includes at least one guide member 410 and at least one limiting member 420. The guide member 410 is protrudingly connected to either the side of the light source 200 near the mounting member 300 or the side of the optical element 100 near the mounting member 300. The limiting member 420 is disposed on the mounting member 300, circumferentially surrounding the mounting member 300, and its two ends are adjacent to each other corresponding to the two ends of the mounting member 300. The guide member 410 is slidably connected to the limiting member 420.

[0028] The aforementioned beam angle adjustment structure 10 allows at least one of the optical element 100 and the light source element 200 to be rolled onto the mounting member 300, enabling the optical element 100 and / or the light source element 200 to roll relative to the mounting member 300. This allows the light emitting surface of the optical element 100 and / or the light emitting surface of the light source element 200 to rotate 360 ​​degrees relative to the mounting member 300, thereby achieving 360-degree adjustment of the illumination angle of the beam angle adjustment structure 10. A guide member 410 is protruding from the side of the optical element 100 or the light source element 200 near the mounting member 300, and the guide member 410 slides... Connected to the limiting member 420, the limiting member 420 is arranged around the circumference of the mounting member 300, and the two ends of the limiting member 420 are arranged adjacent to the two ends of the mounting member 300 in a one-to-one correspondence. That is, the limiting member 420 is arranged around the circumference of the mounting member 300, and the limiting member 420 extends to the two ends of the mounting member 300 respectively, so that the optical member 100 or the light source member 200 slides between the guide member 410 and the limiting member 420 relative to the two ends of the mounting member 300. In other words, on the basis of adjustable illumination angle, the beam angle is adjustable, thereby improving the uniformity of illumination and the light efficiency utilization rate.

[0029] Please refer to the following: Figures 1 to 3 In one embodiment, the limiting member 420 is a limiting sliding hole. Further, the limiting member is a limiting sliding groove or a limiting sliding track, which effectively improves the guiding sliding stability of the guide member.

[0030] Please refer to the following: Figures 1 to 3 In one embodiment, the guide 410 is engaged with and slidably disposed on the limiting member 420, which further improves the sliding stability of the guide 410 on the limiting member 420.

[0031] Please refer to the following: Figures 2 to 5 In one embodiment, the beam angle adjustment structure 10 further includes a rotating member 500, which is rotatably connected to the mounting member 300. The rotation axis of the rotating member 500 is parallel to the length direction of the mounting member 300, and the rotating member 500 is at least partially exposed on the mounting member 300. A guide member 410 is connected to the rotating member 500 and is located at the limiting member 420. The guide member 410 slides on the limiting member 420 under the transmission of the rotating member 500, so that the rotating member 500 rotates about the length direction of the mounting member 300 as the rotation axis. With the guide member 410 connected to the rotating member 500, the rotating member 500 drives the guide member 410 to slide on the limiting member 420 when it rotates. The rotating member 500 is at least partially exposed on the mounting member 300, which improves the convenience of beam angle adjustment.

[0032] Please refer to the following: Figures 2 to 5In one embodiment, the mounting member 300 includes a mounting shell 310 and a rotating receiving shell 320. The mounting shell 310 is connected to the rotating receiving shell 320, and the side of the mounting shell 310 near the rotating receiving shell 320 and the side of the rotating receiving shell 320 near the mounting shell 310 form a mounting gap 301. A rotating member 500 is disposed at the mounting gap 301 and rotatably connected to the mounting shell 310. The rotating member 500 is at least partially exposed outside the mounting shell 310, and the rotation axis of the rotating member 500 is parallel to the length direction of the mounting shell 310. At least one of the optical member 100 and the light source member 200 is rotatably disposed on the mounting shell 310 or the rotating receiving shell. A limiting member 420 is disposed on the rotating receiving shell 320 and surrounds the mounting shell 310. The mounting shell 310 is circumferentially arranged, and the two ends of the limiting member 420 are adjacent to the two ends of the mounting shell 310 in a one-to-one correspondence. The optical element 100 or the light source element 200 is disposed on the side of the rotating receiving shell 320 away from the mounting shell 310 and connected to the guide member 410. The guide member 410 passes through the limiting member 420 and is connected to the rotating member 500. Thus, the main bearing body of the rotating member 500 is the mounting shell 310 and the rotating receiving shell 320. That is, the optical element 100 or the light source element 200 does not need to bear the weight of the rotating member 500. While ensuring the sliding stability of the rotating member 500 driving the guide member 410 on the limiting member 420, the rolling smoothness of the optical element 100 or the light source element 200 relative to the mounting member 300 is improved.

[0033] Please refer to the following: Figures 2 to 5 In one embodiment, the optical element 100 is disposed on the side of the rotating receiving housing 320 away from the mounting housing 310 and connected to the guide 410, so that the optical element 100 slides between the two ends of the mounting housing 310 via the guide 410, and the rolling smoothness of the optical element 100 relative to the mounting housing 310 is improved.

[0034] In one embodiment, the light source is disposed on the side of the rotating receiving housing away from the mounting housing and connected to the guide, so that the light source slides between the two ends of the mounting housing via the guide, and the rolling smoothness of the light source relative to the mounting housing is improved.

[0035] Please refer to the following: Figures 2 to 5 In one embodiment, the optical element 100 is tumbledly connected to the adjusting member 700, and the side of the adjusting member 700 away from the optical element 100 is connected to the guide member 410. Furthermore, the light source element 200 is connected to the mounting housing 310, further ensuring effective tumble of the optical element 100 relative to the mounting housing 310, thereby ensuring the adjustability of the illumination angle of the beam angle adjustment structure 10.

[0036] In one embodiment, the optical element is rotatably connected to the adjustment control, the side of the adjustment control away from the optical element being connected to the guide. Furthermore, the light source element is rotatably connected to the mounting housing, further ensuring effective rotatability of the optical element relative to the mounting housing, thereby ensuring the adjustability of the illumination angle of the beam angle adjustment structure.

[0037] In one embodiment, the light source is tumbled onto the adjusting member, and the side of the adjusting member away from the light source is connected to the guide member. Furthermore, the optical element is connected to the mounting housing, further ensuring effective tumble of the light source relative to the mounting housing, thereby ensuring the adjustability of the illumination angle of the beam angle adjustment structure.

[0038] In one embodiment, the light source is tumbled onto the adjusting member, and the side of the adjusting member away from the light source is connected to the guide member. Furthermore, the optical element is tumbled onto the mounting housing, further ensuring effective tumble of the light source relative to the mounting housing, thereby ensuring the adjustability of the illumination angle of the beam angle adjustment structure.

[0039] Please refer to the following: Figures 2 to 5 In one embodiment, the rotating member 500 is provided with a sliding area 501. The extending direction of the sliding area 501 is parallel to the rotation axis of the rotating member 500. The guide member 410 is engaged with the sliding area 501 and slides in the sliding area 501. That is, the guide member 410 is allowed to slide on the rotating member 500 relative to the two ends of the mounting member 300. In this way, the rotating member 500 does not need to slide with the guide member 410 relative to the two ends of the mounting member 300. Thus, it is only necessary to ensure that the guide member 410 is engaged with the sliding area 501 and slides along the sliding area 501 during processing. This avoids the need to precisely process the mounting member 310 to match the sliding track of the limiting member 420 so that the rotating member 500 and the guide member 410 slide synchronously relative to the two ends of the mounting member 310, thereby reducing the processing accuracy requirements of the beam angle adjustment structure 10.

[0040] Please refer to the following: Figure 2 and Figure 4 In one embodiment, the mounting shell 310 has a rotating ring area 302 on the side near the rotating member 500. The rotating ring area 302 is arranged around the circumference of the mounting shell 310. The rotating member 500 is partially engaged with the rotating ring area 302 and slides in the rotating ring area 302, which better ensures the engagement stability and rotational stability of the rotating member 500 relative to the mounting shell 310.

[0041] Please refer to the following: Figures 1 to 4In one embodiment, a rotation marker 600 is provided on the outer wall of the mounting member 300. The rotation marker 600 is arranged circumferentially around the mounting member 300. The guide member 410 is partially exposed on the mounting member 300 and moves along the extension direction of the rotation marker 600. Further, the rotation marker 600 is exposed on the mounting shell 310 and is arranged circumferentially around the mounting shell 310. The rotating member 500 is partially exposed on the mounting shell 310 and moves along the extension direction of the rotation marker 600. That is, the guide member 410 is indirectly exposed on the mounting shell 310 through the rotating member 500, and the guide member 410 moves indirectly along the extension direction of the rotation marker 600 through the rotating member 500. This directly reflects the rotational position of the guide member 410, and combined with the rotation marker 600, intuitively reflects the angle of rotation, that is, more intuitively reflects the focusing angle of the light source 200 or the optical component 100, improving the user's convenience and accuracy in adjusting the beam angle.

[0042] This application also provides a lighting fixture. One embodiment of the lighting fixture includes an assembly of the beam angle adjustment structure of any of the above embodiments. The assembly is connected to the outer wall of a mounting member, and the mounting member is connected to the building body via the assembly. Further, please refer to... Figures 1 to 3 In this embodiment, the beam angle adjustment structure includes an optical element 100, a light source 200, a mounting element 300, and a telescopic adjustment assembly 400. At least one of the optical element 100 and the light source 200 is rotatably disposed on the mounting element 300. Light is configured to be emitted through the light source 200 and at least partially incident into the optical element 100 for redirection and emission. The telescopic adjustment assembly 400 includes at least one guide 410 and at least one limiting member 420. The guide 410 is protrudingly connected to either the side of the light source 200 near the mounting element 300 or the side of the optical element 100 near the mounting element 300. The limiting member 420 is disposed on the mounting element 300 and is circumferentially arranged around the mounting element 300. The two ends of the limiting member 420 are adjacent to the two ends of the mounting element 300 in a one-to-one correspondence. The guide 410 is slidably connected to the limiting member 420.

[0043] The aforementioned lighting fixtures employ a beam angle adjustment structure, which effectively improves the uniformity of illuminance and the luminous efficiency of the lighting fixtures.

[0044] Compared with the prior art, the present invention has at least the following advantages: The beam angle adjustment structure 10 of this invention allows at least one of the optical element 100 and the light source element 200 to be rolled onto the mounting member 300, enabling the optical element 100 and / or the light source element 200 to roll relative to the mounting member 300. This allows the light emitting surface of the optical element 100 and / or the light emitting surface of the light source element 200 to rotate 360 ​​degrees relative to the mounting member 300, thereby achieving 360-degree adjustment of the illumination angle of the beam angle adjustment structure 10. A guide member 410 is protruding from the side of the optical element 100 or the light source element 200 near the mounting member 300, and the guide member 410 slides... The optical component 100 or the light source component 200 is movably connected to the limiting member 420. The limiting member 420 is arranged around the circumference of the mounting member 300, and the two ends of the limiting member 420 are adjacent to the two ends of the mounting member 300 respectively. That is, the limiting member 420 is arranged around the circumference of the mounting member 300, and the limiting member 420 extends to the two ends of the mounting member 300 respectively, so that the optical component 100 or the light source component 200 slides between the guide member 410 and the limiting member 420 relative to the two ends of the mounting member 300. In other words, on the basis of adjustable illumination angle, the beam angle is adjustable, thereby improving the uniformity of illumination and the light efficiency utilization rate.

[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
