Description

Technical Field

[0001] This utility model belongs to the technical field of lighting devices with adjustable light emission angle, specifically relating to a lamp body structure and a spotlight. Background Technology

[0002] LED lighting fixtures, such as downlights or spotlights, can be installed in ceilings or suspended ceilings using either surface mounting or recessed mounting methods. Recessed spotlights are mostly direct-lighting, and to adjust the beam angle, adjustable fixtures use a damping and limiting structure with the lamp body and a face ring.

[0003] In some small lighting fixtures used in museums, science and technology museums, due to size limitations, installing two damping rings or damping coils on the inner side of the front ring results in a small force-bearing area and insecure installation, leading to the spherical lamp body detaching during angle adjustment rotation. Furthermore, because the contact area between the damping ring structure and the spherical lamp body is too small, the damping force between the front ring and the lamp body is uneven, making it impossible to properly fix the adjustment angle.

[0004] Existing technology discloses an LED lamp adjustment structure, including a lamp body and an adjustment base. The adjustment base includes an inner ring fixed to the outer surface of the lamp body, a middle ring sleeved outside the inner ring, and an outer ring sleeved outside the middle ring. The outer ring and the middle ring are radially rotatably connected via a damping shaft; the middle ring and the outer ring are axially damped rotatably connected. This LED lamp adjustment structure assembles the lamp body with the inner ring by sequentially sleeved inner ring, middle ring, and outer ring, with the inner ring and middle ring connected by a damping shaft. This adjustment structure requires multiple sleeved rings and is not suitable for damped angle adjustment of small lamps. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Example 1 Reference Figures 1-5 This embodiment provides a lamp body structure 100 for use in small or mini lamps, such as small / mini spotlights or track lights. The lamp body structure 100 includes a lamp body 1, a front cylinder 2, and an adjustment assembly 3. The front cylinder 2 is installed inside the lamp body 1, and the lamp body 1 can rotate relative to the adjustment assembly 3 to adjust the lighting angle. The lamp body 1 includes a first housing 11 and a second housing 12, which are connected together. The lamp body 1 has an internal mounting cavity 13 and an external adjustment wall 14.

[0031] In some embodiments, the first housing 11 and the second housing 12 are detachably connected together, for example by threaded connection or snap-fit. When it is necessary to replace internal components, such as light source components or front cylinder, the first housing 11 and the second housing 12 can be disassembled and then reassembled. In some embodiments, the first housing 11 and the second housing 12 are non-detachably fixedly connected, for example by using adhesive to completely fix the two together to ensure the internal sealing effect.

[0032] In this embodiment, the first housing 11 is provided with an external thread 111, and the second housing 12 is provided with an internal thread 121. The first housing 11 and the second housing 12 are detachably screwed together by the external thread 111 and the internal thread 121.

[0033] The adjusting wall 14 has an arcuate structure or a generally spherical structure. In some embodiments, the adjusting wall 14 has a smooth arcuate structure, which makes the rotation smoother. In other embodiments, the adjusting wall 14 may have a grid or microstructure on its surface to increase the friction during the adjustment process, but the rotation will be slower.

[0034] The front tube 2 is installed in the mounting cavity 13 of the lamp body 1. The front tube 2 may be provided with a light-emitting structure for controlling the light emitted by the light-emitting element.

[0035] The adjustment component 3 is rotatably connected to the lamp body 1. Specifically, by adjusting the relative position of the adjustment component 3 and the lamp body 1, different light emission angles of the lamp body can be obtained. The adjustment component 3 includes an adjustment seat 31 and a damping element 32. The damping element 32 is provided with a damping structure 320 and is embedded in the inner side of the adjustment component 31. In this embodiment, both the adjustment seat 31 and the damping element 32 have annular structures, and the height of the adjustment seat 31 is greater than the height of the damping element 32.

[0036] The adjustment seat 31 is connected to the adjustment wall 14 of the lamp body 1 via a damping member 32. The damping structure 320 located inside the damping member 32 is at least interference-fitted with the adjustment wall 14 at the second housing 12. Since the lamp body 1 is assembled from the first housing 11 and the second housing 12, part of the adjustment wall 14 located on the outside of the lamp body 1 is the outer wall of the first housing 11, and the other part is the outer wall of the second housing 12.

[0037] The damping structure 320 is interference-fitted with the adjusting wall 14 located at the second housing 12, thereby making the damping element 32 tightly fitted with the lamp body 1 and generating friction, so that the lamp body is stably limited relative to the adjusting seat after the lighting angle is adjusted.

[0038] Furthermore, the damping element 32 is a deformable annular elastic element. For example, the damping element 32 can be a single piece of rubber, silicone, or a single piece of elastic plastic.

[0039] The damping member 32 includes a first sidewall 321 and a second sidewall 322, which are respectively disposed on the inner and outer sides of the damping member 32. In this embodiment, the damping structure 320 consists of a plurality of protrusions 323 disposed on the first sidewall 321, which abut against the adjusting wall 14.

[0040] A plurality of protrusions 323 circumferentially disposed on the first sidewall 321 form a damping ring 324, and at least two damping rings 324 are provided. It is understood that the protrusions 323 on the damping ring 324 are discontinuously distributed circumferentially. In this embodiment, the protrusions 323 are evenly distributed in a ring on the first sidewall 321 to form two damping rings 324. A protrusion 323 of one damping ring 324 is adjacent to and aligned with a protrusion 323 of the other damping ring 324 in the height direction.

[0041] In some embodiments, the protrusions 323 are evenly distributed in a ring on the two damping rings 324 formed by the first sidewall 321, which abut against the adjusting wall 14 located on the second housing 12, that is, the two damping rings 324 are both interference-fitted with the adjusting wall 14 located on the second housing 12.

[0042] In some embodiments, the protrusions 323 are evenly distributed in a ring on two damping rings 324 formed on the first sidewall 321. One damping ring 324 abuts against the adjusting wall 14 located on the first housing 11, and the other damping ring 324 abuts against the adjusting wall 14 located on the second housing 12. That is, the two damping rings 324 are respectively connected to the adjusting walls 14 located on the first housing 11 and the second housing 12 with an interference fit.

[0043] In this embodiment, the damping element 32 is a single annular damping sheet, which can be made of rubber or silicone. This single annular damping sheet has the characteristics of good deformability and high fit. Compared with the two small damping blocks or rubber rings in the prior art, it has the advantages of simple assembly and good damping effect, and is suitable for small lamps or mini lamps with limited internal installation space.

[0044] The damping element 32 is installed in the adjusting seat 31 in the following way: the adjusting seat 31 has a receiving groove 311 on its inner side. The groove of the receiving groove 311 is adapted to the damping element 32. The damping element 32 is fitted and connected in the receiving groove 311, that is, the second side wall 322 of the damping element 32 is fitted and connected to the bottom of the receiving groove 311, and the first side wall 321 is flush with or partially protrudes from the inner side of the adjusting seat 31.

[0045] After the damping element 32 is embedded and installed into the adjusting seat 31, the first housing 11 and the second housing 12 are screwed together to form a complete spherical adjusting wall 14. The adjusting wall 14 is connected to the first side wall 321 of the damping element 32. Specifically, the damping structure 320 on the first side wall 321 is configured with multiple protrusions 323 arranged in a ring. The protrusions 323 have a small ball structure and are interference-fitted with the adjusting wall 14. Since the damping element 32 is an elastic rubber or silicone part, it will generate a strong damping force when it is interference-fitted with the adjusting wall 14, without affecting the angle adjustment by rotating the spherical lamp body 1 during use. After the rotation adjustment is completed, the damping structure 320 is tightly fitted with the lamp body 1 and generates friction, so that the light emission angle of the spherical lamp body 1 is fixed, avoiding the situation where the angle is unstable due to insufficient damping force.

[0046] The lamp body structure provided in this embodiment allows for rotational adjustment between the lamp body and the adjustment base via a single damping component. This damping component is a deformable annular elastic component, and the damping component has a damping structure with multiple protrusions on its first side wall. The damping structure is interference-fitted with the adjustment wall located in the second housing, so that the lamp body is stably limited relative to the adjustment base after the lighting angle adjustment is completed.

[0047] Example 2 exist Figures 1-5 Based on reference Figure 6 This embodiment improves upon Embodiment 1 by modifying the damping component. Specifically, the damping component 32 is a deformable annular elastic component. For example, the damping component 32 can be a single piece of rubber, silicone, or a single piece of elastic plastic.

[0048] The damping element 32 includes a first sidewall 321 and a second sidewall 322, which are respectively disposed on the inner and outer sides of the damping element 32. Unlike Embodiment 1, the damping structure 320 in this embodiment consists of a plurality of protrusions 325 disposed on the first sidewall, which abut against the adjusting wall 14.

[0049] Preferably, in this embodiment, two protrusions 325 are provided, and both protrusions abut against the adjusting wall 14 located on the second housing 12. That is, both protrusions 325 are interference-fitted with the adjusting wall 14 located on the second housing 12.

[0050] For other structures in this embodiment, please refer to the relevant description in Embodiment 1, which will not be repeated here.

[0051] In this embodiment, the damping element is a single annular damping sheet. This single annular damping sheet has the characteristics of good deformability and high fit. The damping structure is a convex ring set on the first side wall. Compared with two small damping blocks or rubber rings, the convex ring and the damping block are an integral whole, so there will be no detachment. At the same time, the damping strength is greater, the assembly is simple, and it is suitable for small lamps or mini lamps with limited internal installation space.

[0052] Example 3 exist Figures 1-6 Based on reference Figure 7 This embodiment provides a spotlight, which can be a small or mini spotlight, suitable for locations with limited installation space. The spotlight includes a light-emitting component 200, a lens 300, a face ring 400, and a retaining spring 500, as well as the lamp body structure 100 of Embodiment 1 or Embodiment 2. The light-emitting component 200 includes a substrate 201 and LED beads 202, with the LED beads 202 fixedly attached to the substrate 201. The light-emitting component 200 is fixedly connected to the first housing 11, and the lens 300 is mounted on and covering the light-emitting component 200. The face ring 400 is fixedly connected to the adjustment seat 31 of the adjustment component 3, and the retaining spring 500 is fixedly connected to the outside of the face ring 400 for engaging with an opening in the ceiling or suspended ceiling.

[0053] When in operation, the light emitted by the light-emitting component 200 passes through the lens 300, the front cylinder 2, and the face ring 400 and is emitted to the outside.

[0054] The spotlight provided in this embodiment allows for angle adjustment of the lamp body relative to the adjustment seat by rotating the lamp body. The protrusions or rings of the limiting structure undergo elastic deformation to adapt to the adjustment wall of the lamp body. After the adjustment is completed, the lamp body is limited and fixed to avoid the situation where the adjustment angle is unstable due to insufficient damping force.

[0055] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this 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 obvious substitutions all fall within the protection scope of this utility model.
