Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a light emission angle adjustment device and lighting equipment. Background Technology

[0002] The focusing mechanism of a lamp typically involves mounting the light source on the lamp housing and the lens on a rotating ring. A grooved surface is provided on the lamp housing, and the rotating ring is positioned within this groove, allowing adjustment of the distance between the lens and the light source as it rotates relative to the lamp housing. However, when assembling the rotating ring into the grooved surface, this small protrusion is prone to breakage, affecting the assembly yield of the lamp. Alternatively, adding other components after the rotating ring is assembled into the lamp housing, such as a structure that allows sliding along a spiral groove, can penetrate the rotating ring and extend into the spiral groove, as described in utility model application number CN201921947329.3. The patent application describes a method where a first focusing ring is positioned within a spiral groove of a second focusing ring via a bead, and the first and second focusing rings are rotatably connected. This causes a change in the relative distance between the lens and the light source, thus achieving focusing. However, since the bead needs to pass through the first focusing ring and extend into the spiral groove, the first and second focusing rings require precise alignment, and the assembly precision of the bead and the first focusing ring needs to be high. Otherwise, it may be difficult for the bead to pass through the first focusing ring, increasing the assembly difficulty of the lamp; or it may result in poor assembly stability of the bead on the first focusing ring, reducing the adjustment stability of the light emission angle of the lamp.

[0020] This application provides a light emission angle adjustment device. The light emission angle adjustment device includes a housing, a sliding member, and an assembly. The housing has a receiving groove for accommodating a light-emitting element and an optical element. One end of the sliding member is connected to the outer wall of the light-emitting element or the outer wall of the optical element. The assembly is arranged around the periphery of the receiving groove, is housed within the receiving groove, and is connected to the housing. A wedge-shaped notch is provided on the side of the assembly near the bottom of the receiving groove, and the wedge-shaped notch and the bottom of the receiving groove together form a threaded slide. When the assembly is connected to the housing, the other end of the sliding member slides into the wedge-shaped notch and engages with the threaded slide, and the sliding member is slidably connected to the threaded slide. Further, the wedge-shaped notch is an axially cut notch formed on the assembly, but the notch does not axially sever the assembly. The side of the assembly located at the notch and near the bottom of the receiving groove is a wedge-shaped surface. The wedge-shaped surface and the bottom of the receiving groove form the inner wall of the threaded slide, and the notch, together with part of the receiving groove, serves as the receiving space for the threaded slide.

[0021] The aforementioned light emission angle adjustment device allows the assembly to be housed within the receiving groove, with the wedge-shaped notch of the assembly and the bottom of the receiving groove forming a threaded slide. When the assembly is connected to the housing, the other end of the sliding member slides into the wedge-shaped notch and engages with the threaded slide. The sliding member is slidably connected to the threaded slide. That is, the sliding member is first housed in the receiving groove before the assembly. Then, when the assembly is connected to the housing—that is, when the assembly is housed in the receiving groove and connected to the housing—the sliding member slides into the wedge-shaped notch and engages with the threaded slide, thus slidably connecting to both the assembly and the housing. This reduces cracking damage when the sliding member engages with the threaded slide. It improves the assembly yield, and the sliding member and the assembly can be assembled to the housing sequentially without requiring precise alignment and engagement of the sliding member with both the housing and the assembly. This significantly reduces assembly difficulty and improves the stability of the light emission angle adjustment of the lamp.

[0022] To better understand the light emission angle adjustment device of this application, the following further explanation is provided: Please refer to the following: Figures 1 to 3 One embodiment of the light emission angle adjustment device 10 includes a housing 100, a slider 200, and an assembly 300. The housing 100 has a receiving groove 101 for accommodating a light-emitting element and an optical element. One end of the slider 200 is connected to the outer wall of the light-emitting element or the outer wall of the optical element. The assembly 300 is arranged around the peripheral wall of the receiving groove 101, is housed within the receiving groove 101, and is connected to the housing 100. A wedge-shaped notch 301 is provided on the side of the assembly 300 near the bottom of the receiving groove 101, and the wedge-shaped notch 301 and the bottom of the receiving groove 101 together form a threaded slide 102. When the assembly 300 is connected to the housing 100, the other end of the slider 200 slides into the wedge-shaped notch 301 and engages with the threaded slide 102, and the slider 200 is slidably connected to the threaded slide 102.

[0023] The aforementioned light emission angle adjustment device 10 allows the assembly 300 to be housed within the receiving groove 101, and the wedge-shaped notch 301 of the assembly 300 and the bottom of the receiving groove 101 together form a threaded slide 102. When the assembly 300 is connected to the outer shell 100, the other end of the sliding member 200 slides into the wedge-shaped notch 301 and engages with the threaded slide 102, and the sliding member 200 is slidably connected to the threaded slide 102. That is, the sliding member 200 is housed in the receiving groove 101 before the assembly 300. Then, when the assembly 300 is connected to the outer shell 100, that is, when the assembly 300 is housed in the receiving groove 101 and connected to the outer shell 100, the sliding member 200 slides into the wedge-shaped notch 301 and engages with the threaded slide 102, and is slidably connected to the assembly 300 and the outer shell 100 respectively, reducing cracking damage when the sliding member 200 is engaged with the threaded slide 102. This improves the assembly yield, and the slider 200 and assembly 300 can be assembled onto the housing 100 in sequence. It is not necessary to precisely align and snap the slider 200 onto the housing 100 and assembly 300 respectively, thus achieving a stable connection between the slider 200 and the housing 100 and assembly 300. This significantly reduces the assembly difficulty and improves the stability of the light emission angle adjustment of the lamp.

[0024] Please refer to the following: Figures 1 to 3 In one embodiment, the receiving groove 101 has a connecting groove 103 on its groove wall, and at least a portion of the assembly 300 is engaged with the connecting groove 103, thereby improving the assembly stability of the assembly 300 in the receiving groove 101.

[0025] Please refer to the following: Figures 1 to 3In one embodiment, a wedge-shaped surface 104 is provided at the bottom of the receiving groove 101. The wedge-shaped surface 104 and the wedge-shaped notch 301 are arranged opposite to each other to form a threaded slide 102, which realizes the stable and smooth sliding of the sliding member 200 on the threaded slide 102.

[0026] Please refer to the following: Figures 1 to 3 In one embodiment, the light emission angle adjustment device 10 further includes a rotating member 400, a sliding member 200 connected to the rotating member 400, the rotating member 400 being rotatably connected to the housing 100, and the rotating member 400 being at least partially exposed outside the housing 100. Furthermore, the rotating member 400 and the assembly 300 are positioned to avoid each other, and the rotating member 400 being exposed outside the housing 100 facilitates the user applying force to the rotating member 400, thereby causing the sliding member 200 to slide relative to the assembly 300, thus improving the convenience of adjusting the light emission angle.

[0027] Please refer to the following: Figures 1 to 3 In one embodiment, a rotating member 400 is disposed between the assembly 300 and the outer shell 100, a sliding member 200 passes through the wedge-shaped notch 301 and is connected to the rotating member 400, the assembly 300 is sandwiched between the rotating member 400 and the outer shell 100, and the rotating member 400 is rotatably connected to the outer shell 100 and slidably connected to the assembly 300. Further, the connecting groove 103 is formed by the bottom of the rotating member 400 and the receiving groove 101, and the assembly 300 is snapped into the connecting groove 103. Further, the assembly 300 is fixedly connected to the outer shell 100. Further, when the rotating member 400 rotates relative to the outer shell 100, the rotating member 400 slides relative to the assembly 300. Furthermore, the rotating component 400 is located on the side of the assembly 300 away from the outer shell 100 and on the side of the outer shell 100 close to the assembly 300, that is, the rotating component 400 is located on the inner wall of the outer shell 100 and outside the peripheral wall of the assembly 300. Furthermore, the two ends of the assembly 300 respectively abut against the bottom of the receiving groove 101 and the side of the rotating component 400 close to the bottom of the receiving groove 101, so that the assembly 300 is sandwiched between the rotating component 400 and the outer shell 100, which is conducive to the compact arrangement and assembly of the rotating component 400, the sliding component 200, the assembly 300 and the outer shell 100, and realizes the stable rotation of the rotating component 400, ensuring the stability and convenience of the light emission angle adjustment.

[0028] Please refer to the following: Figures 1 to 3 In one embodiment, a handheld part 410 is connected to the rotating member 400, and the handheld part 410 is exposed outside the housing 100, which further improves the convenience of adjusting the light emission angle.

[0029] Please refer to the following: Figures 1 to 3In one embodiment, an elastic body (not shown) is provided at the threaded slide 102. The elastic body is attached to the bottom of the receiving groove 101 and abuts against the side of the slider 200 near the bottom of the receiving groove 101. Further, the elastic body is attached to a wedge-shaped surface. This improves the engagement stability of the slider 200 with the bottom of the receiving groove 101 and the assembly 300, reduces excessive tightness when the slider 200 slides in the threaded slide 102, and improves the stability and smoothness of the light emission angle adjustment.

[0030] Please refer to the following: Figures 1 to 3 In one embodiment, the light-emitting element is connected to the bottom of the receiving groove 101. Further, the slider 200 is at least partially protruding from the outer wall of the optical element. Further, when the assembly 300 is connected to the housing 100, the assembly 300 is located between the housing 100 and the optical element, and the slider 200, protruding from the optical element, slides into the wedge-shaped notch 301 and is clamped between the assembly 300 and the housing 100, and the slider 200 is slidably connected to the assembly 300 and the housing 100 at the threaded slide 102. Furthermore, the sliding member 200 abuts against the side of the assembly 300 near the bottom of the receiving groove 101 and the bottom of the receiving groove 101, so that the sliding member 200 is clamped between the assembly 300 and the housing 100 and is limited to sliding connection at the threaded slide 102, so that the optical component moves relative to the housing 100, thereby changing the distance between the optical component and the light-emitting component and realizing the adjustment of the light emission angle. This helps to simplify the structure, connection and positional relationship of the assembly 300, the rotating member 400 and the sliding member 200 in the light emission angle adjustment device 10, and thus realizes the simplification of the structure of the light emission angle adjustment device 10 on the basis of convenient and stable adjustment of the light emission angle.

One embodiment of the lighting device includes a light-emitting element, an optical element, and a light emission angle adjustment device according to any of the above embodiments. Both the light-emitting element and the optical element are housed within a receiving groove, and a sliding member is connected to the outer wall of the light-emitting element or the outer wall of the optical element. Further, please refer to... Figures 1 to 3In this embodiment, the light emission angle adjustment device 10 includes a housing 100, a slider 200, and an assembly 300. The housing 100 has a receiving groove 101 for accommodating a light-emitting element and an optical element. One end of the slider 200 is connected to the outer wall of the light-emitting element or the outer wall of the optical element. The assembly 300 surrounds the periphery of the receiving groove 101, is housed within the receiving groove 101, and is connected to the housing 100. A wedge-shaped notch 301 is provided on the side of the assembly 300 near the bottom of the receiving groove 101, forming a threaded slide 102 together with the bottom of the receiving groove 101. When the assembly 300 is connected to the housing 100, the other end of the slider 200 slides into the wedge-shaped notch 301 and engages with the threaded slide 102, and the slider 200 is slidably connected to the threaded slide 102.

Further, a fixing member is provided on the outer wall of the optical element, the optical element is rotatably connected to the fixing member, and a sliding member at least partially protrudes from the fixing member on the side away from the optical element.
