Description

Technical Field

[0001] This application relates to the field of lighting fixture technology, and in particular to a lamp mounting housing module and a lamp. Background Technology

[0002] In current home lighting, in addition to ceiling lights, more and more overhead lights are being used, such as pendant lights and panel lights installed on the ceiling. In addition to achieving the lighting effect, they also play a very beautiful decorative role and are increasingly favored by people.

[0003] Taking a chandelier as an example, it typically includes a base, a suspension wire, and a lamp housing. The base is installed on the ceiling, and the lamp housing is connected to the base via the suspension wire and suspended from the ceiling. Normally, to facilitate the installation and fixation of the base, a bracket is first installed on the ceiling, and then the base is suspended from the bracket. The bracket and base are fixed together by a nested fit of slots and positioning posts. However, in the aforementioned chandelier, the nested fit of the slots and positioning posts has relatively weak load-bearing capacity, resulting in low reliability of the fixed connection between the bracket and the base. Utility Model Content

[0004] In view of this, embodiments of this application provide a lamp mounting housing module and a lamp to solve the above-mentioned technical problems.

[0005] In a first aspect, embodiments of this application provide a lamp mounting housing module, which includes a mounting bracket, a mounting housing, and fasteners. The mounting bracket includes a bracket body and a positioning member, the positioning member being fixedly disposed on the bracket body. The bracket body is used for mounting the lamp at the installation location, and the bracket body has a connecting hole. The mounting housing includes a sidewall, which is arranged circumferentially to form an accommodating space, and the sidewall has a locking groove assembly. The locking groove assembly includes a first positioning groove and a second positioning groove, which extend circumferentially along the sidewall, respectively. The mounting bracket is disposed within the accommodating space, connecting the connecting hole and the second positioning groove, and the positioning member is movably embedded in the first positioning groove. The fastener passes through the second positioning groove and the connecting hole, connecting the sidewall and the bracket body.

[0006] In some embodiments, the sidewall has an axis and is arranged around the axis; the first positioning groove includes a first sliding groove segment and a first locking groove segment that are connected to each other. The first sliding groove segment extends circumferentially along the sidewall, and the first locking groove segment is disposed at one end of the first sliding groove segment and protrudes relative to the first sliding groove segment in the direction of extension of the axis. The positioning member is embedded in the first locking groove segment.

[0007] In some embodiments, the second positioning groove includes a second sliding groove segment and a second locking groove segment that are connected to each other. The second sliding groove segment extends circumferentially along the side wall, and the second locking groove segment is disposed at one end of the second sliding groove segment and protrudes relative to the second sliding groove segment along the axial extension direction. The protrusion direction of the second locking groove segment and the first locking groove segment is the same. The fastener passes through the second locking groove segment and the connecting hole.

[0008] In some embodiments, the length of the first locking groove protruding relative to the first sliding groove is less than or equal to the outer diameter of the positioning member; the connecting hole and the second locking groove are corresponding and connected; the fastener includes a rod and a head connected to one end of the rod; the rod passes through the second locking groove and is locked in the connecting hole; the head abuts against the side wall away from the receiving space.

[0009] In some embodiments, the locking groove group further includes a connecting groove, one end of which penetrates the end of the side wall; the first positioning groove and the second positioning groove are disposed on the same side of the connecting groove, and the ends of the first positioning groove and the second positioning groove are respectively connected to the connecting groove.

[0010] In some embodiments, the sidewall has an axis, the sidewall is arranged around the axis, and the connecting groove extends along the direction of the axis.

[0011] In some embodiments, the first positioning groove and the second positioning groove extend in the same direction relative to the connecting groove, and the length of the first positioning groove and the length of the second positioning groove are the same.

[0012] In some embodiments, the bracket body includes a support portion and a mounting portion. The support portion is connected to one end of the mounting portion and bent relative to the mounting portion. The mounting portion is located at one end of the accommodating space and is used for installation at the installation site. The support portion is stacked on the side wall facing the accommodating space. Positioning elements and connecting holes are provided on the support portion.

[0013] In some embodiments, the mounting housing also includes a bottom wall, which covers one end of the side wall. The mounting part and the bottom wall are spaced apart from each other. The bottom wall is provided with a wire-passing hole for the wires of the lamp to pass through, and the accommodating space is connected to the outside through the wire-passing hole.

[0014] Secondly, embodiments of this application also provide a lighting fixture, which includes a lighting fixture mounting housing module and a light source assembly, wherein the light source assembly is connected to the mounting housing.

[0015] Compared to existing technologies, the lamp mounting housing module provided in this application allows the mounting housing to be hung on the mounting bracket through the nested connection of the positioning member and the first positioning groove. Furthermore, through the nested connection of the fastener with the second positioning groove and the connecting hole, the mounting housing can be locked onto the mounting bracket while being hung on it, thus preventing the mounting housing from rotating or loosening relative to the mounting bracket. The reliability of the fixed connection between the mounting bracket and the mounting housing is relatively high.

[0016] Furthermore, the mounting bracket of the mounting housing module, through positioning components and fasteners, holds the mounting housing, making the overall mounting bracket strong in bearing the weight of the mounting housing. Even if the lamp housing is heavy, it can reduce the risk of load-bearing failure. For example, the fasteners share the load of the positioning components, reducing the risk of breakage or deformation of the positioning components; similarly, the positioning components share the load of the fasteners, avoiding the phenomenon that the fasteners are difficult to tighten due to excessive shear force. Therefore, the overall safety factor of the lamp is high. In addition, during the assembly process, the mounting housing is placed outside the mounting bracket, the positioning components are aligned with the first positioning groove, and the connecting hole is aligned with the second positioning groove. After rotating the mounting housing at a certain angle, the fasteners are inserted into the second positioning groove and the connecting hole. Then, the fasteners are locked to the side wall and the bracket body, and the installation is completed. The operation is relatively convenient and can meet the needs of single-person installation. In practical applications, users can first fix the mounting bracket at the installation site. After the mounting housing and lamp housing are assembled and fixed, the mounting housing and mounting bracket can be connected, fixed, and disassembled by rotating the mounting housing, which can improve installation efficiency and flexibility.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1 This application provides a lamp mounting housing module 100 and a lamp 200 configured with the lamp mounting housing module 100.

[0030] The lamp 200 is used to provide lighting or decorative light. In this embodiment, the specific type of lamp 200 is not limited. For example, the lamp 200 can be a chandelier, ceiling light, downlight, etc. When the lamp 200 is installed and used, it can be fixed to the installation location 500 through the lamp mounting housing module 100.

[0031] The lighting fixture mounting housing module 100 includes a mounting bracket 10 and a mounting housing 20 connected to each other. The mounting bracket 10 is used to fix the mounting housing 20 to the installation location. The mounting housing 20 is used to install and fix components such as the light-emitting element, ballast, or circuit board of the lighting fixture 200. The installation location 500 can be a ceiling, wall, or bracket, etc., and the embodiments of this application do not specifically limit it.

[0032] In this embodiment of the application, the lamp 200 may include a light source assembly 2001 and the aforementioned lamp mounting housing module 100, with the light source assembly 2001 connected to the mounting housing 20. For example, the light source assembly 2001 may be disposed within the cavity formed by the mounting housing 20 to form a product structure such as a flat ceiling light or a downlight; alternatively, the light source assembly 2001 may also be disposed outside the mounting housing 20 to form a product structure such as a decorative ceiling light or a chandelier.

[0033] As a specific example, in this embodiment, the lamp 200 further includes a lamp housing 2002, which is connected to the lamp mounting housing module 100. The light source assembly 2001 is disposed within the lamp housing 2002 and forms emitted light. The mounting housing 20 has a wire-through hole (not shown in the figure), and one end of the lamp housing 2002 has a connector 2003, which can be a cable or other structure. The connector 2003 passes through the wire-through hole and is detachably connected to the lamp mounting housing module 100 to facilitate the maintenance and management of the internal components of the lamp housing 2002. The light source assembly 2001 is disposed outside the mounting housing 20, for example, at the end of the lamp housing 2002 opposite to the connector 2003, making the lamp 200 present as a pendant lamp structure. As an example, the lamp housing 2002 can be a housing with a light-transmitting lampshade. The light source assembly 2001 is disposed within the lamp housing 2002, which can provide dust protection and is also conducive to emitting more uniform light.

[0034] In some examples, the light source assembly 2001 may specifically include a circuit board 2004 and a light-emitting unit 2005. The circuit board 2004 may have an elongated plate structure, and the light-emitting unit 2005 is disposed on the circuit board and emits light towards the side opposite to the lamp housing 2002 and opposite to the connector 2003. This application embodiment does not limit the specific number or type of the light-emitting unit 2005. For example, the number of light-emitting units 2005 may be one or more, and the colors of the light emitted by multiple light-emitting units 2005 may be the same or different. Alternatively, the light-emitting unit 2005 may include at least one of light-emitting elements such as halogen lamps, LED lamps, and incandescent lamps. In specific application examples, the type and number of light-emitting units 2005 can be set according to actual usage requirements to enrich the light emission effect of the lamp 200.

[0035] Please see Figure 2 and Figure 3 In one embodiment of this application, the mounting shell 20 is provided with a receiving space 201, and the mounting bracket 10 is disposed within the receiving space 201. The mounting shell 20 is rotatably fitted over the mounting bracket 10. It should be understood that, since the mounting bracket 10 and the mounting shell 20 are detachable and relatively movable, for ease of description, the descriptions of the mounting bracket 10 and the mounting shell 20 and their detailed features, especially the descriptions of their mating relationship, in this specification are all descriptions of the two after they are assembled, put into use, or in use (hereinafter collectively referred to as "assembled state"), except for the parts specifically described; wherein, the special descriptions include descriptions of the assembly process of the two or descriptions of the separation state of the two.

[0036] In this embodiment, the mounting bracket 10 includes a bracket body 12 and a positioning member 14. The bracket body 12 has a connecting hole 1211, and the positioning member 14 is fixedly disposed on the bracket body 12. The mounting shell 20 includes a side wall 22, which is arranged circumferentially to form the aforementioned receiving space 201. The side wall 22 is provided with a locking groove assembly 24, which includes a first positioning groove 241 and a second positioning groove 243, which extend circumferentially along the side wall 22. In the assembled state, the mounting bracket 10 is disposed in the receiving space 201 such that the connecting hole 1211 and the second positioning groove 243 are connected, and the positioning member 14 is movably embedded in the first positioning groove 241.

[0037] In this embodiment, the mounting shell module 100 further includes a fastener 30. In the assembled state, the fastener 30 passes through the second positioning groove 243 and the connecting hole 1211, connecting the side wall 22 and the bracket body 12. In this embodiment, the fastener 30 can be a threaded fastener such as a screw or bolt, or other types of fasteners such as a pin.

[0038] Therefore, in the lamp mounting housing module 100 provided in this application embodiment, the mounting housing 20 can be hung on the mounting bracket 10 through the nested connection of the positioning member 14 and the first positioning groove 241. Furthermore, through the nested connection of the fastener 30 with the second positioning groove 243 and the connecting hole 1211, the mounting housing 20 can be locked on the mounting bracket 10 while being hung on it, thus avoiding the phenomenon of rotation or loosening of the mounting housing 20 relative to the mounting bracket 10. The reliability of the fixed connection between the mounting bracket 10 and the mounting housing 20 is relatively high.

[0039] Furthermore, the mounting bracket 10 of the mounting housing module 100 holds the mounting housing 20 by means of the positioning element 14 and the fastener 30, making the overall load-bearing capacity of the mounting bracket 10 for the mounting housing 20 stronger. Even if the lamp housing 2002 has a heavy weight, the risk of load-bearing failure can be reduced. For example, the fastener 30 shares the load of the positioning element 14, reducing the risk of the positioning element 14 breaking or deforming; and the positioning element 14 shares the load of the fastener 30, avoiding the phenomenon that the fastener 30 is difficult to tighten due to excessive shear force. Therefore, the overall safety factor of the lamp 200 is high. In addition, during assembly, the mounting shell 20 is fitted over the mounting bracket 10, aligning the positioning element 14 with the first positioning groove 241 and the connecting hole with the second positioning groove 243. After rotating the mounting shell 20 by a certain angle, the fastener 30 is inserted into the second positioning groove 243 and the connecting hole 1211. Then, the fastener 30 is locked to the side wall 22 and the bracket body 12, thus completing the installation. The operation is relatively convenient and can meet the needs of single-person installation. In practical applications, users can first fix the mounting bracket 10 at the installation site. After the mounting shell 20 and the lamp shell 2002 are assembled and fixed, the mounting shell 20 and the mounting bracket 10 can be connected, fixed, and disassembled by rotating the mounting shell 20, which can improve installation efficiency and flexibility.

[0040] The following sections will introduce each component of the lamp 200 and the lamp mounting housing module 100, as well as the specific structure of each component.

[0041] Please continue reading. Figure 3 The mounting bracket 10 includes the bracket body 12 and the positioning element 14 mentioned above.

[0042] The bracket body 12 is used to fix it to the installation location 500, such as the ceiling, wall, etc. The bracket body 12 includes a mounting part 121 and a support part 123.

[0043] As an example, the mounting part 121 is generally plate-shaped and is used to be stacked on the mounting surface of the mounting location 500 during assembly, and can be connected to the mounting surface by a number of fastening connectors. For this purpose, the bracket body 12 may be provided with a number of through holes for connection, through which fastening connectors pass and are locked to the mounting location 500.

[0044] The support portion 123 is connected to one end of the mounting portion 121 and bent relative to the mounting portion 121. As an example, the support portion 123 is generally plate-shaped and is generally perpendicular to the mounting portion 121. In the installed state, the support portion 123 extends relative to the mounting portion 121 in a direction away from the installation location 500 for mounting and connecting the mounting shell 20. In this embodiment, there are two support portions 123, which are respectively disposed at both ends of the mounting portion 121 and are spaced apart from each other to connect and support the two sides of the mounting shell 20, making the connection force more balanced and the structure more robust and reliable. In other examples, there can be one or more support portions 123. One support portion 123 can be disposed at the end or middle of the mounting portion 121 to ensure a relatively stable connection structure with the mounting shell 20. Multiple support portions 123 can be sequentially spaced around the outer periphery of the mounting portion 121, and the distances from the geometric center of the multiple support portions 123 to the mounting portion 121 are all approximately the same.

[0045] Both the connecting hole 1211 and the positioning member 14 are provided on the support portion 123. In this embodiment, the positioning member 14 is provided on the support portion 123 at one end relatively close to the mounting portion 121, and the connecting hole 1211 is located on the support portion 123 at one end relatively far from the mounting portion 121. In other examples, the positions of the connecting hole 1211 and the positioning member 14 can be interchanged, or they can be arranged in other ways, for example, the distances between the connecting hole 1211 and the positioning member 14 and the mounting portion 121 are approximately equal.

[0046] As an example, the positioning member 14 is generally columnar, located on the side of the support portion 123 opposite to the mounting portion 121, and protrudes relative to the surface of the support portion 123. The direction of the protrusion of the positioning member 14 is generally perpendicular to the support portion 123, so that it can firmly "hook" the mounting shell 20 when it is embedded in the first positioning 241. In the embodiments of this application, the connection relationship between the positioning member 14 and the support portion 123 is not limited. For example, the positioning member 14 can be assembled on the support portion 123 by welding, threaded connection, etc.; or, the positioning member 14 can be integrally formed with the support portion 123, and the forming process of both can be bending, stamping, or casting, etc.

[0047] The connecting hole 1211 can be a through hole, extending through both opposite sides of the support portion 123. The axis of the connecting hole 1211 can be perpendicular to the support portion 123, that is, approximately parallel to the mounting portion 121. As another example, the connecting hole 1211 can be a blind hole, with its open end located on the side of the support portion 123 away from the mounting portion 121, to facilitate assembly and connection with the fastener 30. In a specific example, the number of connecting holes 1211 and the number of positioning elements 14 can both be set to be the same as the number of support portions 123, that is, a set of connecting holes 1211 and positioning elements 14 are provided on the support portion 123 in a one-to-one correspondence.

[0048] The mounting housing 20 is connected to the mounting bracket 10 via the support portion 123. More specifically, the mounting housing 20 is connected to the mounting bracket 10 via the positioning element 14 on the support portion 123. The mounting housing 10 includes a bottom wall 26 and the aforementioned side wall 22. The side wall 22 is generally annular, thus having an axis O. The side wall 22 is arranged around the axis O to define the aforementioned receiving space 201, making the side wall 22 generally cylindrical to facilitate its rotation and docking with the mounting bracket 10 during assembly. In the assembled state, the mounting bracket 10 is located in the receiving space 201, the mounting portion 121 of the mounting bracket 10 is located at one end of the receiving space 201, and the support portion 123 is stacked on the side of the side wall 22 facing the receiving space 201.

[0049] The bottom wall 26 is generally flat and covers one end of the side wall 22. In the assembled state, the bottom wall 26 is located at the end of the side wall 22 away from the mounting part 121, and the bottom wall 26 and the mounting part 121 are spaced apart from each other. The bottom wall 22 is provided with a through hole 261 for the wires of the lamp 200 to pass through, and the receiving space 201 is connected to the outside through the through hole 261. In the assembled state, the connector 2003 of the lamp 200 can pass through the through hole 261 and connect with components such as ballasts and circuit boards in the receiving space 201.

[0050] The side wall 22 is provided with the first positioning groove 241 and the second positioning groove 243 as described above.

[0051] The first positioning groove 241 extends approximately along a circumference of the side wall 22. During assembly, the positioning member 14 is embedded at one end of the first positioning groove 241. When the mounting housing 20 rotates relative to the mounting bracket 10, the positioning member 14 slides relative to the first positioning groove 241 to position itself in a specific location, thereby positioning the mounting housing 20 in the designated position. In some examples of this application, the first positioning groove 241 may be a through-groove structure that extends radially through opposite sides of the side wall 22 to provide sufficient space for the insertion of the positioning member 14. In other examples, the first positioning groove 241 can be a groove structure with a groove bottom, which can be set on the side of the sidewall 22 facing the receiving space 201 (i.e., the inner surface of the sidewall). In this case, by setting a positioning member 14 of appropriate size, for example, making the length of the positioning member 14 less than or equal to the depth of the first positioning groove 241, the positioning member 14 can be reliably embedded in the groove of the first positioning groove 241. And since the first positioning groove 241 does not penetrate the outer surface of the sidewall 22, the appearance of the lamp 200 is more concise.

[0052] Please see Figure 4 The first positioning groove 241 includes a first sliding groove segment 2411 and a first locking groove segment 2413 that are connected. The first sliding groove segment 2411 extends circumferentially along the side wall 22, and the first locking groove segment 2413 is disposed at one end of the first sliding groove segment 2411 and protrudes relative to the first sliding groove segment 2411 in the extension direction along the axis O of the side wall 22. In the assembled state, the positioning member 14 is embedded in the first locking groove segment 2413. As a specific example, the extension direction of the first sliding groove segment 2411 is approximately parallel to the plane where the bottom wall 26 is located. The first locking groove segment 2413 protrudes in a direction away from the bottom wall 26 relative to the first sliding groove segment 2411, so as to bend relative to the first sliding groove segment 2411. Therefore, when the positioning member 14 is embedded in the first locking groove segment 2413, the groove wall of the first locking groove segment 2413 can limit the positioning member 14, so that the positioning member 14 can no longer move along the extension direction of the first sliding groove segment 2411, thereby restricting the rotational freedom of the entire mounting shell 20 relative to the mounting bracket 10.

[0053] Specifically, please refer to Figure 5 and Figure 6 In the assembled state, the first sliding groove segment 2411 extends substantially along the horizontal plane, and the first locking groove segment 2413 protrudes relative to the first sliding groove segment 2411 in the opposite direction of gravity G (i.e., upward). During assembly, the positioning member 14 is first inserted into position A1 of the first sliding groove end 2411, and then the mounting shell 20 is rotated so that the positioning member 14 is located at position B1 (e.g., ...). Figure 7As shown, under the influence of gravity, the mounting shell 20 will fall downwards, causing the positioning member 14 to be located at position C1, that is, the positioning member 14 is embedded in the first locking groove 2413. When the installer removes the external force, the mounting shell 20 will be hung on the positioning member 14 through the first locking groove 2413 under the influence of gravity. The positioning member 14 can not only bear the weight of the mounting shell 20, the lamp shell 2002, and the light source module 2001, but also abut or contact the side wall of the first locking groove 2413, thereby restricting the mounting shell 20 from rotating relative to the mounting bracket 10 again, ensuring the mounting shell 20 is firm and reliable.

[0054] Please refer to it again. Figure 4 In some embodiments, the extension length L1 of the first sliding groove segment 2411 is much greater than the radial dimension of the positioning member 14. The extension length L1 of the first sliding groove segment 2411 is much greater than the length H1 of the first locking groove segment 2413 protruding relative to the first sliding groove segment 2411; for example, L1 can be greater than or equal to three times H1. The length H1 of the first locking groove segment 2413 protruding relative to the first sliding groove segment 2411 is less than or equal to the outer diameter of the positioning member 14. This not only allows the positioning member 14 to abut or contact the sidewall of the first locking groove segment 2413 to achieve the effect of restricting rotation, but also simplifies the structure of the first positioning groove 241 and makes the relative movement of the positioning member 14 in the first positioning groove 241 smoother. As a specific example, the positioning element 14 can be a cylindrical structure, the first sliding groove segment 2411 can be a straight groove structure, and the first locking groove segment 2413 can be a semi-circular groove structure. When the first locking groove segment 2413 is "hung" on the positioning element 14 under the action of gravity, the contact surface area between the two is larger, which can prevent relative swaying between the mounting shell 20 and the mounting bracket 10, and achieve a firm and reliable limiting. In other examples, the positioning element 14 can be a prism structure, and the first locking groove segment 2413 can also be a square groove corresponding to the positioning element 14. Of course, the outlines of the two do not have to correspond strictly. For example, the positioning element 14 can be a prism structure while the first locking groove segment 2413 can be a semi-circular groove structure, and so on.

[0055] The second positioning groove 243 includes a second sliding groove segment 2431 and a second locking groove segment 2433 that are connected to each other. The second sliding groove segment 2431 extends circumferentially along the side wall 22, and the second locking groove segment 2433 is disposed at one end of the second sliding groove segment 2431 and protrudes relative to the second sliding groove segment 2431 in the extension direction along the axis O of the side wall 22. In the assembled state, the connecting hole 1211 and the second locking groove segment 2433 correspond to and are connected. As a specific example, the extension direction of the second sliding groove segment 2431 is approximately parallel to the plane where the bottom wall 26 is located. The second locking groove segment 2433 protrudes in a direction away from the bottom wall 26 relative to the second sliding groove segment 2431, so as to bend relative to the second sliding groove segment 2431. Therefore, when the connecting hole 1211 and the second locking groove segment 2433 correspond and communicate, the fastener 30 can be sequentially inserted into the second locking groove segment 2433 and the connecting hole 1211, and lock the mounting shell 20 onto the bracket body 12, thereby restricting the rotational freedom of the mounting shell 20 relative to the mounting bracket 10, and being able to share part of the load of the positioning member 14.

[0056] Specifically, please refer to Figure 5 and Figure 6 In the assembled state, the second sliding groove segment 2431 extends substantially along the horizontal plane, and the second locking groove segment 2433 protrudes relative to the second sliding groove segment 2431 in the opposite direction of gravity G (i.e., upward). During assembly, firstly, the connecting hole 1211 is aligned with position A2 of the second locking groove segment 2433, and then the mounting housing 20 is rotated so that the connecting hole 1211 is aligned with position B2 (e.g., ...). Figure 7 As shown, under the influence of gravity, the mounting shell 20 will fall downwards, so that the connecting hole 1211 is directly opposite the position C2, that is, the connecting hole 1211 is directly opposite the second locking groove 2433. At this time, the installer can use the fastener 30 to pass through the second locking groove 2433 and the connecting hole 1211 in sequence, and lock the mounting shell 20 to the bracket body 12 by the fastener 30. Therefore, the second locking groove 2433 can be hung on the fastener 30. The fastener 30 can not only bear the weight of the mounting shell 20, the lamp shell 2002, and the light source module 2001, but also press the mounting shell 20 tightly against the mounting bracket 10, thereby restricting the mounting shell 20 from rotating relative to the mounting bracket 10 again, ensuring the mounting shell 20 is firm and reliable.

[0057] Please refer to it again. Figure 4In some embodiments, the extension length L2 of the second sliding groove segment 2431 is much greater than the radial dimension of the connecting hole 1211, and the extension length L2 of the second sliding groove segment 2431 is much greater than the protrusion length H2 of the second locking groove segment 2433 relative to the second sliding groove segment 2431. For example, L2 can be greater than or equal to three times H2. The protrusion length H2 of the second locking groove segment 2433 relative to the second sliding groove segment 2431 is less than or equal to the radial dimension of the connecting hole 1211, which simplifies the structure of the second positioning groove 243 and ensures that the fastener 30, which is matched with the connecting hole 1211, can be smoothly installed. As a specific example, the fastener 30 can be a cylindrical structure, the second sliding groove segment 2431 can be a straight groove structure, and the second locking groove segment 2433 can be a semi-circular groove structure. In other examples, the second locking groove segment 2433 can also be a square groove structure, etc.

[0058] It should be understood that the "straight groove" structure described in the above embodiments of this application specification should not be limited to these grooves being strictly straight lines. Since the first positioning groove 241 and the second positioning groove 243 are formed by hollowing out the cylindrical configuration of the sidewall 22, the first positioning groove 241 and the second positioning groove 243 inevitably possess the arc-shaped extension profile or extension path defined by the cylindrical shape of the sidewall 22. Therefore, the above-mentioned "straight groove" can be understood as a structure that can be presented as a straight extension in the orthographic projection view of these grooves, such as... Figure 4 and Figure 5 The orthographic projection view is shown below.

[0059] In some embodiments of this application, the fastener 30 can be a threaded fastener such as a screw or bolt, and the connecting hole 1211 can be a corresponding threaded hole. For example, please also refer to... Figure 3 and Figure 4 The fastener 30 may include a rod 32 and a head 34 connected to one end of the rod 32. The rod 32 passes through the second locking groove 2433 and is locked in the connecting hole 1211. The head 34 abuts against the side wall 22 opposite to the receiving space 201, thus ensuring that the mounting housing 20 is securely locked onto the mounting bracket 10. Specifically, the outer diameter of the head 34 may be larger than the protrusion height H2 of the second locking groove 2433. The rod 32 has external threads, and the diameter of the rod 32 matches the diameter of the connecting hole 1211, so that when the rod 32 passes through the second locking groove 2433 and is locked in the connecting hole 12111, the head 34 can abut against the outer surface of the mounting housing 20. In other examples, the rod 32 may be a stud structure, and the head 34 may be a nut structure; these will not be elaborated upon in this specification.

[0060] In some embodiments of this application, the first positioning groove 241 and the second positioning groove 243 extend in roughly the same direction on the side wall 22. For example, the first positioning groove 241 and the second positioning groove 243 are arranged approximately parallel to each other. Therefore, during the installation of the mounting shell 20, after it is fitted onto the outer periphery of the mounting bracket 10, a single rotation alignment can be performed to align the positioning member 14 with the designated position of the first positioning groove 241 and the connecting hole 1211 with the designated position of the second positioning groove 243, making the installation operation relatively convenient.

[0061] exist Figure 3 In the illustrated embodiment, the first positioning groove 241 and the second positioning groove 243 can be arranged side by side along the axis O of the side wall 22. Correspondingly, the positioning member 14 and the connecting hole 1211 are also arranged side by side along the axis O of the side wall 22. Further, in this embodiment, the locking groove assembly 24 may also include a connecting groove 245, one end of which penetrates through the end of the side wall 22. The first positioning groove 241 and the second positioning groove 243 are disposed on the same side of the connecting groove 245, and the ends of the first positioning groove 241 and the second positioning groove 243 are respectively connected to the connecting groove 245.

[0062] Specifically, please refer to Figure 5 The connecting groove 245 has a first end 2451 and a second end 2453, which are located at opposite ends of the connecting groove 245. The first end 2451 penetrates the end face of the side wall 22 away from the bottom wall 26, thus forming an opening. During assembly, the positioning member 14 is inserted into the connecting groove 245 from the opening of the first end 2451. The second end 2453 is located at the end of the connecting groove 245 near the bottom wall 26, and the second positioning groove 243 communicates with the second end 2453. Furthermore, the first positioning groove 241 and the second positioning groove 243 extend in the same direction relative to the connecting groove 245. The length L1 of the first positioning groove 241 and the length L2 of the second positioning groove 243 are approximately the same. Therefore, during the assembly process, after the positioning member 14 enters the connecting groove 245 and is aligned with the first positioning groove 241, rotating the mounting shell 20 in one direction once will make the positioning member 14 correspond to the designated position of the first positioning groove 241 (e.g., reaching the end of the first positioning groove 241 or reaching the first locking groove segment 2413) and make the connecting hole 1211 correspond to the designated position of the second positioning groove 243 (e.g., reaching the end of the second positioning groove 243 or reaching the second locking groove segment 2433). The installation operation is relatively convenient.

[0063] In this embodiment, the connecting groove 245 extends along the axis O, allowing the positioning member 14 to be inserted into the connecting groove 245 using only a downward pulling force (human force or gravity, etc.). Furthermore, the positioning member 14 does not need to rub or collide with the groove wall of the connecting groove 245, reducing installation difficulty and avoiding unnecessary wear on the positioning member 14. As a specific example, the extending direction of the connecting groove 245 can be approximately parallel to the axis O. In other examples, the connecting groove 245 can extend obliquely on the side wall 22 or along a curve. For example, the connecting groove 245 extends in a straight line and is not parallel to the axis O; the two are not strictly parallel, which can appropriately reduce the processing difficulty and cost of the connecting groove 245.

[0064] In some embodiments of this application, the number of locking groove groups 24 can be set to two, with the two locking groove groups 24 located on opposite sides of the side wall 22, for example, the two locking groove groups 24 can be located on the same diameter of the side wall 22. The two locking groove groups 24 are provided corresponding to the two support portions 123, and each locking groove group 24 is correspondingly provided with the positioning member 14 and the connecting hole 1211 on the corresponding support portion 123; correspondingly, the number of fasteners 30 can also be set to two, with the two fasteners 30 corresponding one-to-one with the two locking groove groups 24 and connected to the corresponding connecting hole 1211, so that the force between the mounting shell 20 and the mounting bracket 10 is more balanced after connection. In other embodiments, the number of fasteners 30, locking groove groups 24, and support portions 123 can be set to three or more. In some embodiments, the number of fasteners 30, locking groove groups 24, and support portions 123 does not have to be equal. For example, the number of locking groove groups 24 can be twice or more the number of support portions 123, as long as the support portions 123 correspond to a portion of the locking groove groups 24.

[0065] In the embodiments provided in this application, the first positioning groove 241 and the second positioning groove 243 are arranged side by side along the axis O of the sidewall 22, and both are connected to the same connecting groove 245. However, it should be understood that in other embodiments, the positional relationship between the first positioning groove 241, the second positioning groove 243, and the connecting groove 245 may have different characteristics. For example... Figure 8As shown, the first positioning groove 241 and the second positioning groove 243 can extend circumferentially along the sidewall 22, but they do not necessarily need to be side-by-side along the axis O. The first positioning groove 241 and the second positioning groove 243 can be arranged on the same circumference of the sidewall 22, or they can be arranged on different circumferences. Correspondingly, the connecting hole 1211 and the positioning member 12 do not necessarily need to be side-by-side along the axis O. They can be arranged on the same circumference of the sidewall 22, or they can be arranged on different circumferences. In this example, there can be multiple connecting grooves 245. The first positioning groove 241 and the second positioning groove 243 are respectively connected to different connecting grooves 245. Even more, a connecting groove 245 can be configured only for the first positioning groove 241 to facilitate the embedding of the positioning member 14, while the second positioning groove 243 does not need to be connected to any connecting groove 245. There are other variations, which will not be listed in this specification.

[0066] It should be understood that the feature of the first positioning groove 241 or the second positioning groove 243 extending circumferentially along the side wall 22 as described in this application specification should not be narrowly interpreted as the first positioning groove 241 or the second positioning groove 243 extending strictly in the circumferential direction of the side wall 22, nor should it be narrowly interpreted as the extension plane of the first positioning groove 241 or the second positioning groove 243 necessarily coinciding with the circumferential plane of the side wall 22; the above feature should be understood as follows: the extension direction of the first positioning groove 241 or the second positioning groove 243 is basically parallel to the circumferential plane of the side wall 22. For example, there is a certain angle between the plane where the extension path of the first positioning groove 241 or the second positioning groove 243 is located and a certain circumferential plane of the side wall 22. This angle can be less than or equal to 30 degrees (for example, it can be 30 degrees, 25 degrees, 20 degrees, 15 degrees, 10 degrees, 5 degrees, etc.), as long as it is ensured that when the mounting shell 20 is rotated during the assembly process, the positioning member 14 can generate relative movement in the first positioning groove 241.

[0067] In summary, in the lamp mounting housing module 100 provided in this application embodiment, the mounting housing 20 can be hung on the mounting bracket 10 through the nested connection of the positioning member 14 and the first positioning groove 241. Furthermore, through the nested connection of the fastener 30 with the second positioning groove 243 and the connecting hole 1211, the mounting housing 20 can be locked on the mounting bracket 10 while being hung on it, thus preventing the mounting housing 20 from rotating or loosening relative to the mounting bracket 10. The reliability of the fixed connection between the mounting bracket 10 and the mounting housing 20 is relatively high.
