Description

Technical Field

[0001] The present application relates to the technical field of lamps, and more particularly, to a reflective cup assembly and a lamp. Background Art

[0002] Existing lamps typically include a reflector, a light source bracket (base), and a light source. The light source is mounted on the bracket, and the reflector needs to be connected to the bracket and fit over the light source. Existing reflectors use a rotating snap-fit ​​structure, meaning the reflector needs to be inserted into the bracket and then rotated to allow the connecting portion on the reflector to snap into place on the bottom surface of the bracket, thereby securing the reflector to the bracket. Consequently, the reflector and light source bracket require rotation and extraction during assembly and disassembly, resulting in inefficient reflector removal and installation.

[0003] The light source bracket may be installed inside the heat sink. In this case, the reflector needs to be inserted into the heat sink and then rotated to achieve installation. However, the gap between the outer wall of the reflector and the inner wall of the heat sink is small, making it difficult to grasp and rotate the reflector, resulting in low installation and removal efficiency. In summary, the reflector and light source bracket of the prior art are difficult to remove and install. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0031] In this application, unless otherwise indicated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of a device in actual use or operation, specifically in the drawing directions of the accompanying drawings; whereas "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "including" means "including but not limited to." Terms such as first, second, and third are used merely as designations and do not impose numerical requirements or establish a sequential order.

[0032] Please refer to Figures 1 to 4 The embodiment of the present application provides a reflective cup assembly 10, which includes:

[0033] Reflective cup 100 and base 200;

[0034] One of the reflective cup 100 and the base 200 is provided with a buckle 210 , and the other is provided with a buckle groove 111 . The buckle 210 is engaged with the buckle groove 111 to connect the reflective cup 100 and the base 200 .

[0035] In this embodiment, because one of the reflector 100 and the base 200 is provided with a latch 210 and the other with a latch groove 111, the reflector 100 and the base 200 are securely connected via the latch 210 and the latch groove 111. During installation, the reflector 100 need only be moved toward the base 200 to engage the latch 210 and the latch groove 111, without rotating the reflector 100. Consequently, the reflector 100 requires fewer installation steps than in the prior art, resulting in more efficient installation and removal. Furthermore, when the base 200 is located within a heat sink, the reflector 100 and base 200 can be installed by simply inserting the reflector 100 directly into the heat sink, eliminating the need to manually grip and rotate the reflector 100. Consequently, the installation efficiency of a lamp equipped with the reflector assembly 10 is also improved.

[0036] For further information, please refer to Figures 1 to 6 The reflector 100 includes a reflector body (not marked in the figure) and a connecting portion 110. The connecting portion 110 is connected to the outer wall of the reflector body and protrudes toward the base 200. A buckle groove 111 is provided on the connecting portion 110. The outer wall of the base 200 is provided with a buckle 210. The buckle 210 protrudes in a direction away from the base 200.

[0037] In this embodiment, if the clip 210 is provided on the reflector 100, since the reflector assembly 10 typically utilizes the method of moving the reflector 100 to achieve installation between the reflector 100 and the base 200, and the base 200 is generally already fixed, the clip 210 on the reflector 100 has a relatively low structural strength and is easily damaged by collision with external components or by collision with the base 200 due to displacement. In this embodiment, the clip 210 is located on the outer wall of the base 200, and the clip groove 111 is located on the reflector 100. Therefore, when the reflector 100 is moved, the connecting portion 110, where the clip groove 111 is located, is necessarily larger than the clip 210, resulting in greater strength and less damage. Furthermore, the connecting portion 110 facilitates user identification of the installation location, allowing the user to quickly align the clip groove 111 with the clip 210, thereby improving the efficiency of installation of the reflector 100 and the base 200.

[0038] It should be understood that please refer to Figure 2 The size of the buckle 210 can be adapted to the buckle slot 111, that is, the size is substantially the same. In this case, the buckle 210 can avoid a small range of movement in the buckle slot 111, which would affect the connection stability between the reflector cup 100 and the base 200. For example, there is a gap between the buckle 210 and the inner wall of the buckle slot 111, and the gap range is 0.01mm to 2mm.

[0039] For further information, please refer to Figure 1 and Figure 3 There are at least two connecting parts 110 , and the connecting parts 110 are evenly spaced along the circumference of the outer wall of the reflective cup body. The inner sidewalls of the connecting parts 110 abut against the sidewalls of the base 200 for clamping the base 200 .

[0040] In an embodiment, to further improve the connection stability between the reflector 100 and the base 200, the connecting portion 110 may be formed into a clamping structure. In this case, the mutually symmetrical connecting portions 110 can clamp the base 200, thereby improving the connection stability between the reflector 100 and the base 200.

[0041] For further information, please refer to Figures 1 to 5 The base 200 is further provided with a contact surface 220, which is provided on the side of the base 200 facing the reflector 100. The outer wall of the reflector body is further provided with a contact portion 120 protruding toward the base 200, and the contact portion 120 abuts against the contact surface 220; the side of the buckle 210 away from the reflector 100 is provided with a first clamping surface 212, and the side of the buckle groove 111 away from the reflector 100 is provided with a second clamping surface 112, and the first clamping surface 212 abuts against the second clamping surface 112.

[0042] In this embodiment, the connection between the clip 210 and the clip groove 111, that is, the cooperation between the first clip surface 212 and the second clip surface 112, can prevent the reflector 100 and the base 200 from separating from each other. However, during the installation of the reflector 100, if excessive force is applied, the clip 210 may be pressed and deformed by the connecting portion 110, the connecting portion 110 may be deformed in a direction away from the reflector 100, the clip 210 may be broken, and the base 200 may be squeezed and deformed downward by the reflector 100. Therefore, the embodiment of the present application is provided with the abutting portion 120 and the abutting surface 220, so that when the abutting portion 120 and the abutting surface 220 abut against each other, the first clamping surface 212 and the second clamping surface 112 also abut against each other. At this time, the reflective cup 100 structure is fixed in the direction of separation by the first clamping surface 212 and the second clamping surface 112, and is fixed in the direction of approaching each other by the abutting portion 120 and the abutting surface 220, thereby achieving a stable connection of the reflective cup 100 in the up and down directions.

[0043] For further information, please refer to Figures 1 to 5 There are multiple abutting portions 120 and multiple connecting portions 110 , and the multiple connecting portions 110 and the multiple abutting portions 120 are symmetrically distributed along the rotation axis 20 of the reflective cup 100 , and the connecting portion 110 is located between adjacent abutting portions 120 .

[0044] In this embodiment, because there are multiple connecting portions 110 and multiple abutting portions 120, and they are all symmetrically distributed along the rotation axis 20 of the reflector 100, with the connecting portions 110 located between adjacent abutting portions 120, when the reflector 100 and the base 200 are connected to each other, the force applied to the connection between the reflector 100 and the base 200 is evenly distributed in the XY plane. This effectively prevents the reflector 100 from falling off the base 200 due to shaking or collision, thereby improving the stability of the reflector assembly 10.

[0045] For further information, please refer to Figure 3 and Figure 6 A first clamping surface 212 is provided on the side of the buckle 210 away from the reflective cup 100, and a second clamping surface 112 is provided on the side of the buckle groove 111 away from the reflective cup 100, and the first clamping surface 212 abuts against the second clamping surface 112; the first clamping surface 212 and the second clamping surface 112 form an angle A, and the range of the angle A is 30° to 60°.

[0046] In this embodiment, since the first clamping surface 212 and the second clamping surface 112 form an angle A, and the angle A ranges from 30° to 60°, after the reflective cup 100 is mounted on the base 200, the reflective cup 100 can be moved along the Figure 3By rotating the reflector 100 in a clockwise or counterclockwise direction, with the bottom center of the reflector 100 as the rotation point, the reflector 100 and the base 200 can be quickly separated. In this manner, the reflector assembly 10 of this embodiment can prevent the reflector 100 from separating from the base 200 in the vertical direction while also allowing the reflector 100 to be quickly separated from the base 200 during rotation, thereby improving the efficiency of disassembly of the reflector assembly 10. It should be understood that the second engaging surface 112 can form an angle with the horizontal plane (the XY plane in the figure) or can be parallel to each other. Preferably, the angle A is within a range of 35°.

[0047] For further information, please refer to Figure 3 and Figure 6 The second clamping surface 112 is provided with an edge 113 in the direction toward the base 200 , and the edge 113 abuts against the first clamping surface 212 , so as to make the buckle 210 and the buckle groove 111 in line contact.

[0048] In this embodiment, the edge 113 abuts against the first engaging surface 212, providing resistance for the reflective cup 100 to separate from the base 200 in the vertical direction. Figure 3 When the reflector 100 is rotated clockwise or counterclockwise with the bottom of the center of the reflector 100 as the rotation point, the edge 113 is in line contact with the first clamping surface 212, so it can slide along the first clamping surface 212 until it slides out of the first clamping surface 212, thereby realizing the quick disassembly of the reflector 100.

[0049] For further information, please refer to Figures 1 to 5 A guide groove 221 is provided on the outer wall of the base 200 , the shape and size of the connecting portion 110 are adapted to the guide groove 221 , at least part of the connecting portion 110 is located in the guide groove 221 , and the buckle 210 is located in the guide groove 221 .

[0050] In this embodiment, the buckle 210 and the buckle groove 111 are usually small and difficult to align. Therefore, in this embodiment, the shape and size of the connecting portion 110 are adapted to the guide groove 221 so that when the reflector cup 100 and the base 200 are connected, the guide groove 221 guides the connecting portion 110, that is, guides the buckle groove 111 on the connecting portion 110 to align with the buckle 210, thereby improving installation efficiency.

[0051] Furthermore, the examination Figure 3 and Figure 6 The buckle 210 is provided with a guide surface 211 in the direction of the reflective cup 100 , and the guide surface 211 forms an angle B with the inner side wall of the connecting portion 110 , and the angle B ranges from 5° to 85°.

[0052] In this embodiment, the connecting portion 110 is typically elastic. Because an angle B is formed between the guide surface 211 and the inner wall of the connecting portion 110, when the connecting portion 110 approaches the buckle 210 in the vertical direction, the guide surface 211 can cause the connecting portion 110 to deform away from the reflector 100, preventing the bottom of the connecting portion 110 from abutting against the buckle 210 and causing wear on the buckle 210, thereby increasing the service life of the reflector assembly 10. Accordingly, the present application also provides a lamp, comprising the reflector assembly 10 according to any of the above embodiments. The angle B is preferably 28°.

[0053] In this embodiment, because one of the reflector 100 and the base 200 in the lamp is provided with a buckle 210 and the other is provided with a buckle groove 111, the reflector 100 and the base 200 can be fixedly connected by the connection method of the buckle 210 and the buckle groove 111. During installation, the reflector 100 only needs to be moved toward the base 200 so that the buckle 210 and the buckle groove 111 engage to complete the installation, without rotating the reflector 100. Therefore, the lamp assembly steps are reduced compared to the prior art. In addition, when the base 200 is located inside the heat sink, the reflector 100 and the base 200 can be installed by simply inserting the reflector 100 directly into the heat sink. In summary, the lamp installation and disassembly efficiency is high.

[0054] The reflector cup assembly 10 and the lamp provided in the embodiments of the present application are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the method and core concept of the present application. At the same time, for those skilled in the art, according to the concept of the present application, there may be changes in the specific implementation methods and application scope. In summary, the contents of this specification should not be understood as limiting the present application.
