Description

Technical Field

[0002] To improve the dynamic scene reconstruction capability of lighting fixtures, i.e., to enhance their adaptability to different scenarios, many lighting fixtures are now designed with adjustable illumination angles. For example, the invention patent application with application number CN202411749749.6 allows the optical component to rotate and oscillate relative to the light source component. This enables the optical component to be rotatably connected to the second spherical surface of the adjusting component via the first spherical surface of the connecting component, allowing the optical component to be rotatably connected relative to the light source component. This design achieves both convenient adjustment of the illumination angle and simplifies the structure of the illumination angle adjustment. Furthermore, unlike the elephant trunk lamp, it has less impact on the heat dissipation effect of the lighting fixture and has better service life, energy efficiency, and safety. However, the positioning effect of the optical component when rotating relative to the light source component is relatively poor. Utility Model Content

[0037] To better understand the illumination angle setting structure of this application, the following further explanation is provided:

[0038] Please refer to the following: Figures 1 to 3 One embodiment of the illumination angle setting structure 10 includes an optical component 100, a light source component 200, and a damping positioning component. The optical component 100 has a rotating surface, and the light source component 200 has another rotating surface. The damping positioning component includes a damping member 300 and a positioning member 400, which are respectively disposed corresponding to the two rotating surfaces. The damping member 300 is connected to the corresponding rotating surface and can be rotatably fitted onto the other rotating surface. The side of the damping member 300 away from the corresponding rotating surface has a plurality of damping positions 301. The positioning member 400 protrudes from the corresponding rotating surface and is configured to be located at any damping position 301, and can slide away from the corresponding damping position 301 and slide into another damping position 301.

[0039] The aforementioned illumination angle setting structure 10 provides an optical component 100 with one rotating surface and a light source component 200 with another rotating surface. A damping component 300 and a positioning component 400 are correspondingly positioned on the two rotating surfaces. The damping component 300 is connected to the corresponding rotating surface and can rotatably fit against the other rotating surface. The positioning component 400 protrudes from the corresponding rotating surface and is configured to be located at any damping position 301, and can slide away from the corresponding damping position 301 and slide into the other damping position 301. Even if the optical component 100 is rotatably set relative to the light source component 200, the illumination angle of the illumination angle setting structure 10 can be adjusted. The damping component 300 and the positioning component 400 are set between two rotating surfaces, and the positioning component 400 is set at any damping position 301, and can slide away from the damping position 301 and slide into another damping position 301, so that the positioning component 400 and the damping component 300 play a good positioning role in the illumination angle adjustment, and also play a good damping feedback effect in the illumination angle adjustment.

[0040] Please refer to the following: Figures 2 to 4 In one embodiment, the rotating surface of the optical component 100 is a first rotating spherical surface 101. Further, the rotating surface of the light source component 200 is a second rotating spherical surface 201. Further, a damping member 300 is connected to the first rotating spherical surface 101 and rotatably fitted onto the second rotating spherical surface 201. The damping member 300 has multiple damping positions 301 on the side away from the optical component 100. A positioning member 400 protrudes from the second rotating spherical surface 201 and is connected to the light source component 200, thus effectively achieving 360-degree adjustment of the illumination angle.

[0041] Please refer to the following: Figures 2 to 4 In one embodiment, the positioning element 400 is snapped onto any damping position 301, which improves the damping feedback effect and the snapping positioning stability.

[0042] Please refer to the following: Figures 2 to 4 In one embodiment, the damping element 300 is connected to a corresponding rotating surface and can be rolled on another rotating surface. Furthermore, the damping element 300 is connected to a corresponding first rotating spherical surface 101 and can be rolled on a second rotating spherical surface 201, improving the smoothness of the irradiation angle adjustment.

[0043] Please refer to the following: Figures 2 to 4 In one embodiment, the positioning member 400 is an elastic positioning member, configured to elastically extend or retract in a direction away from or towards the damping member 300. Furthermore, when the positioning member 400 is positioned at any damping position 301, the positioning member 400 elastically extends to engage with the damping position 301; when the positioning member 400 slides away from the corresponding damping position 301, the positioning member 400 elastically retracts to disengage from the corresponding damping position 301, improving the smoothness of the irradiation angle adjustment.

[0044] Please refer to the following: Figures 2 to 4 In one embodiment, the positioning member 400 includes a connecting portion 410 and a telescopic portion 420. The connecting portion 410 is connected to the light source assembly 200, and the telescopic portion 420 is connected to the connecting portion 410 and at least partially protrudes from the second rotating spherical surface 201. The telescopic portion 420 is configured to elastically extend and retract in a direction away from or towards the damping member 300. The telescopic portion 420 is engaged at any damping position 301, and the telescopic portion 420 can slide away from the corresponding damping position 301 and slide into another damping position 301. Furthermore, when the telescopic portion 420 is provided at any damping position 301, the telescopic portion 420 elastically extends to engage with the damping position 301; when the telescopic portion 420 slides away from the corresponding damping position 301, the telescopic portion 420 elastically retracts to disengage from the damping position 301, further improving the smoothness of the illumination angle adjustment.

[0045] Please refer to the following: Figures 2 to 4 In one embodiment, the damping position 301 is a damping groove, which improves the damping feedback effect and the stability of the snap-fit ​​positioning.

[0046] Please refer to the following: Figures 2 to 4 In one embodiment, the groove wall of the damping position 301 is a wedge-shaped wall 302, and the positioning member 400 is slidably disposed on the wedge-shaped wall 302, which is disposed away from the light source assembly 200. Further, the positioning member 400 slides into and out of the corresponding damping position 301 via the wedge-shaped wall 302 of any damping position 301. Further, when the telescopic part 420 slides into any damping position 301, the telescopic part 420 slides into the damping position 301 along the wedge-shaped wall 302, and the telescopic part 420 elastically extends away from the optical component until it engages with the damping position 301; when the telescopic part 420 slides out of the damping position 301, the telescopic part 420 slides out of the damping position 301 along the wedge-shaped wall 302, and the wedge-shaped wall 302 pushes the telescopic part 420 to elastically contract towards the optical component 100 until it disengages from the damping position 301, further improving the smoothness of the illumination angle adjustment.

[0047] Please refer to the following: Figures 1 to 2 In one embodiment, a plurality of damping positions 301 are evenly distributed on the corresponding rotating surfaces. Furthermore, the plurality of damping positions 301 are evenly distributed on the first rotating spherical surface 101 to ensure uniform angle change during irradiation angle adjustment.

[0048] In one embodiment, the rotating surface of the optical component is a third rotating spherical surface. Further, the rotating surface of the light source component is a fourth rotating spherical surface. Further, a damping element is connected to the fourth rotating spherical surface and rotatably fitted onto the third rotating spherical surface. The damping element has multiple damping positions on its side away from the light source component. A positioning element protrudes from the third rotating spherical surface and is connected to the optical component, effectively achieving 360-degree adjustment of the illumination angle. It can be understood that the damping element is located on either the first or fourth rotating spherical surface, differing only in its position, but the structure of the damping element is the same, and its structural and positional relationships with the positioning element are identical. Similarly, the positioning element is located on either the second or third rotating spherical surface, differing only in its position, but the structure of the positioning element is the same, and its structural and positional relationships with the damping element are identical. That is, the positioning element can be located in one of the optical component and the light source component, while the damping element is located in the other of the optical component and the light source component, and the structural, positional, and connection relationships between the positioning element and the damping element are all identical. Therefore, this embodiment will not elaborate on the specific structural, positional, and connection relationships of the positioning and damping components relative to the optical and light source components.

[0049] This application also provides a lighting device with an adjustable illumination angle. Please refer to [link / reference]. Figure 5One embodiment of the adjustable illumination angle lighting device 10A includes a housing 20 and an illumination angle setting structure 10 of any of the above embodiments, with a light source assembly 200 or an optical assembly 100 connected to the housing 20. Further, please refer to... Figures 1 to 2 The optical component 100 and the housing 20 are positioned away from each other. Further, in this embodiment, the illumination angle setting structure 10 includes an optical component 100, a light source component 200, and a damping positioning component. The optical component 100 has one rotating surface, and the light source component 200 has another rotating surface. The damping positioning component includes a damping element 300 and a positioning element 400 corresponding to the two rotating surfaces. The damping element 300 is connected to the corresponding rotating surface and can be rotatably fitted onto the other rotating surface. The side of the damping element 300 away from the corresponding rotating surface has multiple damping positions 301. The positioning element 400 protrudes from the corresponding rotating surface and is configured to be located at any damping position 301, and can slide away from the corresponding damping position 301 and slide into another damping position 301.

[0050] The aforementioned adjustable illumination angle lighting device 10A adopts an illumination angle setting structure 10, which effectively realizes the adjustability of the illumination angle, and also enables the adjustable illumination angle lighting device 10A to have a good positioning function for illumination angle adjustment, and a good damping feedback effect for illumination angle adjustment.

The positioning component 400 protrudes from the corresponding rotating surface and is configured to be located at any damping position 301, and can slide away from the corresponding damping position 301 and slide into the other damping position 301.
