TECHNICAL FIELD
[0001] The utility model relates to LED lamps and lanterns, specifically disclose a can change surface ring's down lamp. BACKGROUND
[0002] Reference Figure 6 The down lamp includes a shell 01, a light source 02 and a surface ring 03 are installed in the shell 01, the shell 01 light outlet edge is outwardly folded to form a pressing edge 011, and an elastic pressing sheet 012 is arranged on the outer side of the shell 01. The down lamp is fixed by being clamped on the outer side and the inner side of the ceiling mounting hole through the pressing edge 011 and the elastic pressing sheet 011. Since the size of the pressing edge 011 needs to match the size of the mounting hole, one down lamp can only be adapted to one mounting hole size. In this way, for manufacturers and sellers, the same style of down lamp needs to be produced or stored in multiple sizes, increasing the manufacturing cost and inventory pressure; for users, replacing down lamps of different styles or sizes requires discarding all components of the original down lamp, and the replacement cost is high. INVENTION CONTENTS
[0003] Therefore, it is necessary to provide a down lamp with replaceable surface rings that can reduce manufacturing costs, inventory pressure and replacement costs in view of the problems of the prior art.
[0004] To solve the problems of the prior art, the utility model discloses a down lamp with replaceable surface rings, which comprises a lamp housing, a light source installed in the lamp housing, and a surface ring also installed in the lamp housing. The surface ring comprises a reflector cup, which is detachably installed in the lamp housing at the upper end. The lower edge of the reflector cup is provided with a pressing edge that extends below the light outlet of the lamp housing and surrounds the outer side of the light outlet.
[0005] The utility model has the advantages that the pressing edge is arranged on the lower edge of the surface ring and surrounds the outer side of the light outlet of the lamp housing, and the surface ring and the lamp housing are detachably installed. In this way, for manufacturers, since other components such as the lamp housing can be universal, the same model of down lamp can be applied to down lamp mounting holes of different sizes as long as surface rings of different sizes are manufactured, and even when the model of the down lamp is changed, only the model of the surface ring needs to be changed, without the need to re-open the mold for the lamp housing, greatly reducing the manufacturing cost and production inventory. For sellers, the same style of down lamp only needs to prepare different specifications of surface ring inventory, greatly reducing the sales inventory. For consumers, replacing down lamps of different models or sizes only requires replacing the surface ring, greatly reducing the replacement cost.
[0006] As a further improvement to this utility model, it also includes a lens and a middle ring. The lens is mounted on the middle ring, which is fixed inside the lamp housing. The face ring is detachably fixed to the middle ring, allowing the face ring to be installed using the injection-molded middle ring without the need for a separate mounting structure on the lamp housing. Several inverted clips are provided below the middle ring, and a mounting plate is provided at the upper end of the reflector. The mounting plate has several elongated holes corresponding to the inverted clips. Each elongated hole includes a wide section wider than the inverted clip and a narrow section narrower than the inverted clip. The inverted clips are secured by engaging the narrow section through the wide section of the elongated hole, allowing the face ring to be installed by hand. A limiting step is provided between the wide end and the narrow section of the elongated hole to prevent the face ring from loosening. The reflector has a trumpet-shaped structure, and the pressing edge transitions to the reflector with an arc, increasing the lamp's light effect and the overall integrity of the face ring. The lamp housing and the middle ring are cylindrical, facilitating rotation of the face ring or the lamp housing, and making it easier for the inverted clips to engage and secure in the elongated holes.

[0013] To further understand the features, technical means, specific purposes, and functions of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. The descriptions of component positions (including but not limited to: upper, lower, inner, outer, left, right, etc.) are for reference only when referring to the positions of the components shown in the accompanying drawings. Their purpose is to facilitate understanding of the relative relationships between the components and does not represent an absolute limitation on the scope of protection of this utility model. Those skilled in the art will understand that the description of relative positions may change when the view direction changes, but the essential relative positional relationships between the components remain unchanged.
[0014] refer to Figure 1 A downlight with interchangeable face rings includes a lamp housing 1, inside which a light source 2, a lens 3, a middle ring 4, and a face ring 5 are installed.
[0015] Reference Figures 1 to 5 The lamp shell 1 is cylindrical, with its upper end as the bottom and its lower end as the light outlet 10. The outer upper and bottom parts of the lamp shell 1 are provided with fins 11, and the outer lower part of the lamp shell 1 is provided with two symmetrically distributed elastic pressing pieces 12. The inner bottom part of the lamp shell 1 is provided with a plurality of threaded holes 13. The light source 2 is an LED module, which is fixed by a light source support 21. The light source support 21 is installed on the inner bottom part of the lamp shell 1 by screws through the threaded holes 13. The middle ring 4 is cylindrical, and the lens 3 is fixed in the middle ring 4. The upper end of the middle ring 4 is installed on the inner bottom part of the lamp shell 1 by screws through the threaded holes 13, so that the lens 3 is tightly attached below the light source 2. The lower end of the middle ring 4 is provided with a plurality of barbs 41 arranged around the center. The middle part of the face ring 5 is a horn-shaped light reflecting cup 51. The upper end of the light reflecting cup 51 is provided with a circular mounting plate 52, and the lower edge of the light reflecting cup 51 is provided with a pressing edge 53 extending below the light outlet 10 of the lamp shell and surrounding the outer side of the light outlet 10 of the lamp shell. The mounting plate 52 is provided with a plurality of arc-shaped long holes 54 corresponding to the barbs 41. The long holes 54 include a wide section 541 and a narrow section 542 that are in communication with each other. The width of the wide section 541 is greater than the head of the barb 41, and the width of the narrow section 542 is less than the head of the barb 41. A positioning step 543 is provided between the wide section 541 and the narrow section 542. The pressing edge 53 and the lower edge of the light reflecting cup 51 are circularly arcuate, which can increase the aesthetic appearance and integrity of the face ring 5.
[0016] Reference Figures 1 to 5 When the face ring 5 is installed, the barb 41 of the middle ring 4 is first inserted through the wide section 541 of the long hole 54 of the face ring 5, and then the face ring 5 or the lamp shell 1 is rotated so that the barb 41 is clamped into the narrow section 542 of the long hole 54 by overcoming the step 543. When the face ring 5 is disassembled, the face ring 5 or the lamp shell 1 is rotated in the opposite direction so that the barb 41 is rotated into the wide section 541 of the long hole 54 by overcoming the step 543. The height of the step 543 should be appropriately set so that the barb 41 needs to exert a certain rotational force to overcome it. In this way, after the face ring 5 is installed, it will not be easily removed, but it can still be disassembled and installed by hand. After the down lamp is assembled, the pressing edge 53 of the lower edge of the face ring 5 extends below the light outlet 10 of the lamp shell 1 and surrounds the outer side of the light outlet of the lamp shell 1. In this way, when the down lamp is installed, it can be fixed by clamping the pressing plate 53 and the elastic pressing pieces 12 on the outer side and the inner side of the ceiling mounting hole, respectively.
[0017] After the down lamp is installed, its visible part is mainly the face ring, the utility model sets up the edge pressing outside the light outlet of the lamp shell around the lower edge of the face ring reflection cup, and the face ring and the lamp shell are detachable installation. Thus, for the manufacturers, since the lamp shell and other parts can be universal, the down lamp of the same shape can be applicable to the down lamp installation holes of different sizes as long as the face ring of different sizes is manufactured, even when the down lamp shape is changed, only the face ring shape needs to be changed, the lamp shell does not need to be re-opened, the manufacturing cost and production stock are greatly reduced; for the sellers, the down lamp of the same style only needs to prepare the face ring of different specifications, the sales stock is greatly reduced; for the consumers, the down lamp of different shapes or sizes only needs to replace the face ring, the replacement cost is greatly reduced.
[0018] The above-mentioned embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be pointed out that for the ordinary skilled in the art, several deformations and improvements can be made without departing from the utility model concept, which belongs to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
