Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a spotlight with a variable face ring. Background Technology

[0002] Downlights primarily refer to recessed lighting fixtures designed for installation in ceilings, cabinet surfaces, and other locations. After installation, they conform to the mounting surface to avoid damaging the structural plane. A downlight mainly consists of a lamp body and an internal light source assembly. The lamp body has a cover on one end and spring clips on both sides. The lamp body is inserted into mounting holes on the mounting surface, and the spring clips, in conjunction with the cover, clamp the mounting surface. The cover can also seal the mounting holes.

[0003] For example, Chinese patent CN215722831U discloses a rotatable downlight, which includes a back cover, a plastic part, a front cover, and a lamp body; the back cover has a receiving cavity, and the front cover is disposed at the front opening of the receiving cavity; the plastic part has a ring body and an elastic arm connected to the rear side of the ring body; the lamp body is rotatably installed in the receiving cavity; the plastic part is located between the back cover and the lamp body; the elastic arm acts on the back cover; and the ring body abuts against the lamp body.

[0004] The factory specifications for downlights include the diameter of the lamp body and the corresponding diameter of the cover. For manufacturers and sellers, each lamp requires multiple specifications to meet market demand, increasing production costs and inventory pressure. Users need to cut through holes according to the lamp specifications or select lamps according to the hole size, increasing the complexity of installation and replacement.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a spotlight with a reasonable structure, adaptable to different apertures, and flexible installation using a variable face ring.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The present invention relates to a spotlight with a variable face ring, comprising a lamp body, the front end of which is provided with a cover assembly; the cover assembly includes a face cover, a fixing ring, and an expansion ring, the fixing ring being fitted onto the front end of the lamp body; the expansion ring being movably connected to the fixing ring or the face cover, the expansion ring being able to be retracted and set around the fixing ring, or the expansion ring being unfolded and set on the face cover to expand the outer edge dimension of the face cover.

[0009] According to the above scheme, the expansion ring includes several fan blades, which are arranged at equal angular intervals around the fixed ring. The first end of the fan blade is rotatably connected to the fixed ring or the cover through a hinge structure.

[0010] According to the above scheme, a raised layer is provided on the second end of the fan blade, thereby forming a bend step on the lower end surface of the fan blade; when the expansion ring is unfolded, the bend steps on several fan blades are engaged with the outer edge surface of the cover.

[0011] According to the above scheme, the width of the first end of the fan blade is L1, and the width of the second end of the fan blade is L2, then L1 > L2.

[0012] According to the above scheme, the width of the first end of the fan blade is L1, and the width of the second end of the fan blade is L2. Then L1 < L2, so that when the fan blades are unfolded, they form a complete circular structure around the cover.

[0013] According to the above scheme, the fan blade is a one-piece molded structure. The fan blade is made of an elastic material and bends from the equidistant center line H to both sides, so that the whole fan blade is in the shape of a tile.

[0014] According to the above scheme, the cover assembly also includes at least two spring buckles, and the side wall of the fixing ring is provided with several rivet holes. The spring buckles are connected to the rivet holes by rivets to fix the fixing ring.

[0015] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure. Under the condition that the specifications and dimensions of the lamp body and the cover remain unchanged, the expansion ring can be fitted to the standard size mounting hole, and the expansion ring can be expanded to increase the outer contour size of the cover. Thus, it can be installed even when the diameter of the mounting hole is too large, reducing the number of spare parts on the production side, reducing the installation difficulty, and improving the product competitiveness.

[0023] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figure 1-2 As shown, this utility model discloses a spotlight with a variable face ring, comprising a lamp body 1, the front end of which is provided with a cover assembly. The cover assembly includes a face cover 2, a fixing ring 21, and an expansion ring 3. The fixing ring 21 is fitted onto the front end of the lamp body 1. The expansion ring 3 is movably connected to the fixing ring 21 or the face cover 2. The expansion ring 3 can be retracted and set around the fixing ring 21, or the expansion ring 3 can be unfolded and set on the face cover 2 to expand the outer edge dimension of the face cover 2. This utility model is mainly applied to recessed lighting installations, including downlights, ambient lights, and in-ground lights. The lamp body 1 is installed in a hole in a decorative surface (such as a ceiling, cabinet surface, wall surface, and floor surface). After the lamp body 1 is installed, it is fixed, and the face cover 2 can cover the hole to avoid damaging the integrity of the decorative surface. It is understood that in actual production and installation, there is a matching between the lamp specifications and the opening size. Of course, the primary size specification is that the hole must be larger than the diameter of the lamp body 1, and secondly, the outer diameter of the face cover 2 must be larger than the diameter of the hole. Preferably, in this invention, when the size of the cover 2 is larger than the diameter of the hole (i.e., when the opening size is standard), the expansion ring 3 is retracted, allowing the lamp to be installed normally. When the opening size is larger than the size of the cover 2 (i.e., the selected lamp specifications do not match the opening), the expansion ring 3 is unfolded to enlarge the outer edge size of the cover 2, allowing the lamp to still be installed and cover the opening.

[0026] It is understood that the cover assembly also includes at least two spring clips 11. The sidewall of the fixing ring 21 is provided with several rivet holes 22. The spring clips 11 are connected to the rivet holes 22 by rivets, thereby fixing the fixing ring 21 in place. The spring clips 11 are paired with the face cover 2 or the expansion ring 3 and can be clamped onto the decorative surface. Thus, the spring clips 11 can fix the lamp body 1 in the holes of the decorative surface. The structure and fixing method of the spring clips 11 are existing technologies and will not be described in detail here.

[0027] Specifically, the expansion ring 3 includes a plurality of fan blades 31, which are arranged at equal angular intervals around the fixing ring 21. The first end of each fan blade 31 is rotatably connected to the fixing ring 21 or the cover 2 via a hinge structure 32. The fan blades 31 can rotate on the fixing ring 21 or the cover 2 via the hinge structure 32, allowing the fan blades 31 to be retracted. When the fan blades 31 are extended, they fit against the upper surface of the cover 2, allowing the outer diameter of the cover 2 to be extended, thereby meeting the installation requirements of excessively large opening diameters.

[0028] Furthermore, a raised layer 33 is provided on the second end of the fan blade 31, thereby forming a beveled step 34 on the lower end surface of the fan blade 31. When the expansion ring 3 is unfolded, the beveled steps 34 on several fan blades 31 are engaged with the outer edge surface of the cover 2, so that the raised layer 33 extends outward from the outer edge surface of the cover 2, and the raised layer 33 can be flush with the lower end surface of the cover 2, which is more aesthetically pleasing. Simply put, the fan blade 31 is equivalent to being superimposed on the cover 2. The raised layer 33, by increasing its thickness, can compensate for the height difference between the fan blade 31 and the cover 2, so that the expansion ring 3 is flush with the cover 2 after unfolding, making the decorative surface of the lamp more aesthetically pleasing after installation.

[0029] like Figure 2 As shown, the width of the first end of the fan blade 31 is L1, and the width of the second end of the fan blade 31 is L2, so L1 > L2. It can be understood that the width of the first end of the fan blade 31 is greater than the width of the second end, and the fan blade 31 has a fan-shaped structure with a smaller outer end and a larger inner end. This makes the arrangement of the fan blades 31 more compact after the expansion ring 3 is closed, reducing the space occupied. Conversely, after the expansion ring 3 is unfolded, there will be a larger gap between the fan blades 31.

[0030] Example 2

[0031] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is only that the width of the first end of the fan blade 31 is L1, and the width of the second end of the fan blade 31 is L2, so L1 < L2, thereby forming a complete circular structure around the cover 2 when the fan blades 31 are unfolded. It can be understood that the width of the first end of the fan blade 31 is smaller than the width of the second end, and the fan blade 31 has a fan-shaped structure with a larger outer end and a smaller inner end. This causes interference between the fan blades 31 when the expansion ring 3 is closed, requiring angular misalignment between the fan blades 31 to close, thus occupying a larger space. However, when the expansion ring 3 is unfolded, the fan blades 31 can be spliced ​​into a complete ring structure, eliminating the gaps between the fan blades 31 and improving aesthetics.

[0032] Example 3

[0033] like Figure 4As shown, the difference between this embodiment and Embodiment 2 is only that the fan blade 31 is a one-piece molded structure, made of an elastic material, and bent from the equidistant center line H to both sides, thus making its whole body resemble a tile. It can be understood that the elasticity of the fan blade 31 allows it to deform, avoiding interference between the fan blades 31 when the expansion ring 3 is retracted as in Embodiment 2. Simultaneously, after the expansion ring 3 is unfolded, the fan blades 31 deform under the force of the spring buckle 11, eliminating bending and unfolding flat, thus obtaining a complete annular expansion ring 3.

[0034] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
