Description

Technical Field

[0001] This utility model belongs to the field of downlight technology, specifically relating to a downlight reflector structure that is easy to assemble. Background Technology

[0002] Downlights are a common type of lighting and decorative lamp. They generally include a heat sink, a face ring, a light source, and a lens. For example, CN202220130287.X describes a type of recessed downlight, which includes a main body, a lens assembly, and a front cover. The main body has a light source cavity and a light source element located in the light source cavity. The lens assembly is connected to the light source element and located in the light source cavity. The front cover is detachably connected to the main body and has a first step, a second step, and a positioning recess. The light-emitting end of the lens assembly extends into the positioning recess and abuts against the second step. A clamping space is formed between the first step and the light-emitting end of the lens assembly.

[0003] While it can meet general usage needs, its reflector cups are mostly fixed to the heat sink by clips, and its front cover is directly fixed to the heat sink by screws. Although it can meet general assembly needs, it is easy to disassemble and assemble, and it is difficult to ensure the stability of the position between the front cover and the reflector cup, thus limiting its applicability. Utility Model Content

[0005] The technical solution to achieve the purpose of this utility model is a downlight reflector structure that is easy to assemble, which is set in the main body of the downlight and includes a reflector body and an annular light guide plate set in the reflector body.

[0006] The outer wall of the reflector cup body is integrally formed with several buckle lugs that cooperate with the buckle grooves on the inner wall of the main body. The upper part of the outer side surface of the buckle lugs is provided with buckle protrusions.

[0007] The upper part of the inner wall of the reflector cup body is integrally formed with several sets of parallel hemispherical protrusions.

[0008] The annular light guide plate is inserted into the reflector body, and the outer wall of the annular light guide plate is attached to the inner wall of the reflector body and positioned by pressure from the hemispherical protrusions.

[0009] A further preferred embodiment is that the hemispherical protrusion group comprises a plurality of hemispherical protrusions located on the same vertical line;

[0010] Furthermore, the diameter of the hemispherical protrusions decreases sequentially from top to bottom.

[0011] A further preferred embodiment is that the annular light guide plate is a frustum-shaped annular light guide plate with a large diameter at the upper end and a small diameter at the lower end.

[0012] A further preferred embodiment is that the lower part of the reflector cup body is circular.

[0013] A further preferred embodiment is that the lower part of the reflector cup body is square.

[0014] A further preferred embodiment is that the number of the buckle lugs is three or four.

[0015] This utility model has the following positive effects: The structure of this utility model is reasonably designed. It features snap-fit ​​ears and snap-fit ​​protrusions on the outer wall of the reflector body, allowing for snap-fit ​​connection and positioning during assembly with the main body, thus improving assembly convenience. Furthermore, it has several sets of parallel hemispherical protrusions integrally formed on the upper part of the inner wall. During assembly, the annular light guide plate can be directly snapped into the reflector body and positioned by the hemispherical protrusions, improving assembly convenience and effectiveness, facilitating disassembly and maintenance, and enhancing the overall structural stability and applicability.

In this embodiment, a plurality of snap-fit ​​ears 3 are integrally formed on the outer wall of the reflector body, which cooperate with snap-fit ​​grooves on the inner wall of the main body. Snap-fit ​​protrusions 4 are provided on the upper outer surface of each snap-fit ​​ear. The number of snap-fit ​​ears is three or four. When connecting the reflector body to the main body, it can be directly snapped in through the snap-fit ​​ears and snap-fit ​​protrusions, improving the ease of assembly. Furthermore, in this embodiment, a plurality of parallel hemispherical protrusion groups 5 are integrally formed on the upper inner wall of the reflector body. During assembly, the annular light guide plate is snapped into the reflector body, and the outer wall of the annular light guide plate is attached to the inner wall of the reflector body and positioned by pressure from the hemispherical protrusion groups. The annular light guide plate is positioned by a hemispherical protrusion assembly, which improves the ease of installation. In this embodiment, the annular light guide plate is a frustum-shaped annular light guide plate with a larger diameter at the top and a smaller diameter at the bottom. Furthermore, the upper diameter of the annular light guide plate matches the inner diameter of the reflector body.

[0025] In this embodiment, the hemispherical protrusion group includes multiple hemispherical protrusions 6 located on the same vertical line; and the diameter of the hemispherical protrusions decreases sequentially from top to bottom. The number of hemispherical protrusions can be configured as needed; in this embodiment, there are three. During assembly, the above structure can improve the installation stability and reliability of the annular light guide plate.

[0026] In this embodiment, the lower part of the reflector cup body is circular.

[0027] This utility model has the following positive effects: The structure of this utility model is reasonably designed. It features snap-fit ​​ears and snap-fit ​​protrusions on the outer wall of the reflector body, allowing for snap-fit ​​connection and positioning during assembly with the main body, thus improving assembly convenience. Furthermore, it has several sets of parallel hemispherical protrusions integrally formed on the upper part of the inner wall. During assembly, the annular light guide plate can be directly snapped into the reflector body and positioned by the hemispherical protrusions, improving assembly convenience and effectiveness, facilitating disassembly and maintenance, and enhancing the overall structural stability and applicability.

[0028] Example 2
