Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a lighting panel structure and a lighting fixture. Background Technology

[0002] LED lights are used in many fields due to their superior performance and dimmable properties, such as home lighting, factory lighting, and operating environment lighting.

[0003] Taking lighting in special operating environments as an example, such as lighting inside electrical cabinets, a compact design is usually adopted due to space constraints, and the lamp holder structure is correspondingly small. Current LED light control methods mainly use touch-sensitive or ultra-thin button structures, but these have significant shortcomings in dimming functionality. When LED lights need to support linear dimming of brightness or color temperature, traditional button adjustments are cumbersome and provide a poor user experience. Although knob adjustments offer a better user experience, implementing knob installation in small lamp holder structures faces several difficulties: First, the knob structure requires additional space, which conflicts with the design philosophy of compact lamp holders; second, the protruding knob structure not only affects the overall aesthetics of the product but also increases the risk of damage during transportation and carrying; furthermore, the connection structure between the knob and the lamp holder in existing technologies is often not stable enough, easily becoming loose or shifting during use, affecting dimming accuracy. These problems severely restrict the improvement of the user experience in dimming functionality for small LED lights.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] This application provides a lamp panel structure and a lamp to solve the above-mentioned technical problems.

[0006] In a first aspect, this application provides a lamp panel structure, which is mounted on a lamp holder. The lamp holder is provided with an encoder circuit board. The lamp panel structure includes: a knob bracket, which includes a panel mounting cavity on a first side, a first mating structure on a second side, and a knob driving part that surrounds the panel mounting cavity; the encoder circuit board assembly is provided with a second mating structure that is connected to the first mating structure; the panel mounting cavity is formed by the knob driving part surrounding it; and a panel assembly is disposed within the panel mounting cavity.

[0007] Furthermore, this application also proposes that the first docking structure includes: a support partition formed by radially inwardly extending from the inner wall of the knob drive part and a first connecting part extending axially from the support partition towards the second docking structure, the first connecting part being provided with a plurality of bayonets; the second docking structure includes a second connecting part extending towards the first docking structure, the second connecting part being provided with a plurality of buckles corresponding to the bayonets; the first docking structure is engaged with the buckles of the second docking structure through the bayonets.

[0008] Furthermore, this application also proposes that the first connecting part is provided with a plurality of positioning grooves, and the second connecting part is provided with a plurality of positioning protrusions accordingly, wherein the positioning protrusions are embedded in the positioning grooves when the first docking structure and the second docking structure dock.

[0009] Furthermore, this application also proposes that the support partition and the encoder circuit board assembly are respectively provided with a first through hole and a second through hole, the panel assembly includes a panel bracket, the panel bracket is provided with a first fixing structure corresponding to the positions of the first through hole and the second through hole, the lamp holder is provided with a second fixing structure corresponding to the positions of the first through hole and the second through hole, and the panel assembly is fixed to the second fixing structure through the first fixing structure; the panel assembly is relatively movable to the inner wall of the knob drive part and the support partition.

[0010] Furthermore, this application also proposes that the first fixing structure is a screw hole provided on the panel bracket, and the second fixing structure is a stud provided on the lamp holder.

[0011] Furthermore, this application also proposes that a gap be provided between the panel assembly, the inner wall of the knob drive unit, and the support partition.

[0012] Furthermore, this application also proposes that the panel assembly includes: a panel bracket, an operation panel disposed on one side of the panel bracket, light-guiding silicone disposed on the button holes of the panel bracket, and a touch panel disposed on the other side of the panel bracket, wherein the panel bracket and the touch panel are bonded together by double-sided adhesive.

[0013] Furthermore, this application also proposes that the panel assembly further includes light-shielding cotton disposed between the touchpad and the support partition.

[0014] Furthermore, this application also proposes that the edge of the panel bracket is provided with a first foolproof mounting structure, and the touch panel and / or light-blocking cotton are respectively provided with a second foolproof mounting structure.

[0015] Furthermore, this application also proposes a lamp, including a lamp holder and a light-emitting module connected to the lamp holder, and also including the aforementioned lamp panel structure, the lamp panel structure being disposed on the lamp holder.

[0016] As can be seen from the above, the lamp panel structure and lamp provided in this application achieve compact installation through the docking structure of the knob bracket and the encoder circuit board assembly. At the same time, the panel assembly and the knob drive unit can move relative to each other, which saves space and ensures operational stability. It has the advantages of saving installation space, having a stable and reliable structure, and being easy to operate.

[0017] On the other hand, this utility model also proposes a lamp, including a lamp holder and a light-emitting module connected to the lamp holder, and also includes the above-mentioned lamp panel structure, which is disposed on the lamp holder.

[0018] The technical solutions provided in this application have the following advantages compared with the prior art:

[0019] Compared to existing technologies, traditional knob dimming structures require a separate rotating component protruding from the lamp body surface. This solution, however, integrates the control panel assembly into the mounting cavity formed by the knob drive unit, merging the user interface and knob structure into a planar component. This allows the knob to be directly integrated with the lamp holder's external dimensions. In existing technologies, the knob and circuit board are typically connected laterally, while this solution achieves compact vertical assembly through an axial docking structure, significantly reducing lateral space occupation and maintaining both the lamp holder's compact structure and aesthetic appeal.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0031] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0032] In existing technologies, LED lights typically employ touch-sensitive or ultra-thin button-type structures to achieve dimming functionality. However, due to the necessity of miniaturization and the compact structure of the lamp holder, rotary dimming mechanisms are difficult to integrate. Forcing their integration results in protruding components, leading to issues such as susceptibility to damage during transport and poor aesthetics. For example, in portable lighting applications, traditional rotary structures not only increase the overall thickness, but their exposed parts are also prone to collisions with packaging materials.

[0033] To address the aforementioned issues, those skilled in the art recognized the need to implement knob dimming functionality without increasing the lamp holder's size. Analysis revealed that integrating the knob drive component with the panel mounting structure spatially eliminated protruding components. Further research showed that directly connecting the knob bracket to the circuit board assembly via a mating structure reduced the space occupied by intermediate fixing components. This ultimately led to the technical concept of completely embedding the panel assembly within the mounting cavity enclosed by the knob drive, achieving planar mounting.

[0034] Therefore, as Figure 1-3 As shown, this application proposes a lamp panel structure 001 mounted on a lamp holder, wherein the lamp holder 1 is provided with an encoder circuit board assembly 9. The structure includes a knob bracket 2 and a panel assembly 3. The knob bracket 2 includes a panel mounting cavity 21 disposed on a first side, a first docking structure 22 disposed on a second side, and a knob driving part 23 surrounding the panel mounting cavity 21. The encoder circuit board assembly 9 is provided with a second docking structure 91 connected to the first docking structure 22. The panel mounting cavity 21 is formed by being surrounded by the knob driving part 23, and the panel assembly 3 is disposed within the panel mounting cavity 21.

[0035] In one embodiment, the lamp holder 1 has a columnar structure, including a bottom shell 11 and a top cover 12, with a panel assembly 3 disposed at one end. The appearance of the knob bracket 2 is adapted to the external shape of the lamp holder 1 (i.e., the knob drive part 23 is adapted to the shell shape of the lamp holder 1), so that no local protrusion structure is formed. Specifically, when the lamp holder 1 adopts a cylindrical shape, the knob drive part 23 is also ring-shaped.

[0036] In one embodiment, the encoder circuit board assembly 9 is an integrated structure of the circuit board and the encoder, and the second docking structure 91 is a knob device on the encoder. The encoder circuit board assembly 9 is mounted to the lamp holder 1 by screws 97.

[0037] The knob drive section 23 refers to the annular structure formed around the panel mounting cavity 21, which can be implemented using an injection-molded plastic shell, with its inner wall forming a semi-enclosed space to accommodate the panel assembly 3. The first mating structure 22 refers to the connecting component located on the side of the knob bracket 2 facing the lamp holder 1, which can be an axial extension with a snap-fit, enabling quick assembly through engagement with the snap-fit ​​on the encoder circuit board. The panel mounting cavity 21 refers to the recessed area enclosed by the inner wall of the knob drive section 23, which can be a rectangular or circular cavity structure used to support planar operating components such as touch panels or button panels.

[0038] Specifically, the knob bracket 2 is directly connected and fixed to the encoder circuit board assembly 9 via the first docking structure 22 and the second docking structure 91. The panel assembly is completely confined within the mounting cavity formed by the knob drive part, and its outer surface remains flush with the end face of the knob drive part. The axial connection between the encoder circuit board assembly 9 and the knob bracket 2 creates a compact, vertical assembly relationship. While enclosing the panel assembly, the knob drive part 23 also adapts its appearance to the shape of the lamp holder 1. Its outer edge can be provided with anti-slip texture 231 to assist in rotation operation, achieving the dual functions of dimming and structural concealment.

[0039] Compared with existing technologies, traditional knob dimming structures require a separate rotating component that protrudes from the lamp holder or panel surface. This solution, however, integrates the operating interface and knob structure into a planar component by embedding the panel assembly into the mounting cavity formed by the knob drive part.

[0040] Through the above technical solution, this application achieves complete integration of the knob dimming structure and the lamp holder panel, eliminating the protruding defects of traditional knobs. The structural design of the panel assembly being completely enclosed by the knob drive unit effectively avoids the risk of collision damage during transportation. The spatial integration of the knob drive unit and the panel assembly ensures the flatness of the product appearance while maintaining the dimming function.

[0041] like Figure 4 and Figure 5 As shown, this embodiment further proposes that the knob bracket 2 includes a support partition 221 formed by radially extending inward from the inner wall of the knob drive part 23, and the support partition 221 extends axially to form a first connecting part 222, and the first connecting part 222 is provided with a plurality of bayonet slots 2221; the second docking structure of the encoder circuit board assembly 9 includes a second connecting part 911 and a buckle 912 provided on the second connecting part 911, the position of the buckle 912 corresponding to the bayonet slots 2221; the first connecting part is engaged with the buckle of the second connecting part through the bayonet slots.

[0042] The supporting partition 221 is a plate-like structure extending radially from the inner wall of the knob drive unit towards the center. It can be implemented as a plastic part integrally molded with the knob drive unit 23, providing a load-bearing base for axial connection. The first connecting part 222 is an annular columnar structure extending axially from the supporting partition 221, forming a connection with the second connecting part 911. The bayonet 2221 is a recessed structure formed on the side wall of the first connecting part, which can be a rectangular or trapezoidal notch, used to form a mechanical interlock with the latch 912. The second connecting part 911 is a protruding structure extending from the encoder circuit board assembly 9 towards the supporting partition 221. It can be implemented as a metal spring or plastic part with the latch 912, used to form a vertical limit with the bayonet 2221. The latch 912 can be a protruding structure set on the side wall of the second connecting part, which can be a triangular or semi-circular protrusion, used to embed into the bayonet 2221 for fixation.

[0043] Specifically, the support partition 221 and the inner wall of the knob drive part 23 form an integral structure, directly utilizing the inner wall of the knob drive part 23 as a support base in radial space, avoiding the need for separate support components. The first connecting part 222 extends axially towards the encoder circuit board assembly 9, and multiple slots 2221 distributed on its side wall engage with the latches 912 of the second connecting part 911. During installation, an axial pressing action causes the latches 912 to engage with the slots 2221, completing the mechanical locking. The slots 2221 and latches 912 are evenly distributed circumferentially, forming multiple locking points, which improves connection stability through multi-point stress dispersion. The integrated design of the support partition 221 and the first connecting part 222 eliminates the tolerance accumulation that may occur during separate assembly, ensuring docking accuracy.

[0044] This design utilizes a direct extension of the support plate from the inner wall of the knob drive unit, achieving engagement within the axial space. This eliminates external protruding structures and reduces lateral space occupation. Compared to single-point snap-fit ​​designs, the circumferential distribution of multiple snap-fit ​​points and latches effectively prevents radial misalignment after docking.

[0045] Through the above technical solution, this application achieves rapid tool-free installation of the knob bracket 2 and the encoder circuit board assembly 9. The axial snap-fit ​​method avoids packaging and carrying problems caused by structural protrusion. The integrated design of the support partition and the knob drive unit simplifies the assembly process and reduces the number of parts. The cooperation of multiple sets of bayonets 2221 and buckles 912 forms a reliable connection in a compact space, preventing loosening due to vibration during use.

[0046] This embodiment further proposes to provide a plurality of positioning grooves 2222 on the first connecting part 222 and a plurality of positioning protrusions 913 on the second connecting part 911, so that when the first docking structure 22 and the second docking structure 91 are docked, the positioning protrusions 913 are embedded in the positioning grooves 2222.

[0047] The positioning groove 222 refers to a recessed structure formed on the surface of the first connecting part 222, which can be implemented as a rectangular groove or an arc-shaped groove, and its depth matches the height of the positioning protrusion 913. The positioning protrusion 913 refers to a protruding structure extending outward from the surface of the second connecting part 911, which can be formed by injection molding to create a protrusion whose shape complements that of the positioning groove.

[0048] Specifically, when the knob bracket 2 is assembled with the encoder circuit board assembly 9, the positioning protrusion 913 and the positioning groove 2222 form a physical engagement. This engagement action completes pre-positioning before the buckle 912 contacts the bayonet 2221. Radial displacement is limited by the contact between the side wall of the protrusion and the wall of the groove, and axial movement is limited by the contact between the end face of the protrusion and the bottom of the groove. During the process of the buckle 912 engaging with the bayonet 2221, the cooperation between the positioning groove and the positioning protrusion maintains the relative position stability of the docking structure, avoiding misalignment between the buckle 912 and the bayonet 2221 due to assembly angle deviation. The number of positioning grooves 2222 can be set to three and evenly distributed at 120 degrees, with three corresponding positioning protrusions 913, forming a three-point positioning structure to balance assembly accuracy and structural strength. In addition, when the knob bracket 2 rotates, under the action of the positioning protrusion 913 and the positioning groove 222, it can be ensured that the rotation fed back to the second docking structure 91 when the knob bracket 2 rotates is accurate, and there is no circumferential movement error.

[0049] Through the above technical solution, this application achieves precise alignment of the knob bracket and the encoder circuit board assembly within a limited space, ensuring effective engagement of the latch and the bayonet. The cooperation between the positioning groove and the positioning protrusion forms a dual locking mechanism, which not only prevents positional displacement during assembly but also enhances the anti-torsion capability after docking, avoiding loosening of the connection due to external force vibration.

[0050] In this embodiment, the support partition 221 and the encoder circuit board assembly 9 are respectively provided with a first through hole 2210 and a second through hole 9010. The panel assembly 3 includes a panel bracket 31. The panel bracket 31 is provided with a first fixing structure 311 at the position corresponding to the first through hole 2210 and the second through hole 9010. The lamp holder 1 is provided with a second fixing structure 111 at the position corresponding to the first through hole 2210 and the second through hole 9010. The panel assembly 3 is fixed to the second fixing structure 111 through the first fixing structure 311. The panel assembly 1, the inner wall of the knob drive part 23, and the support partition 221 are relatively movable.

[0051] The first through hole 2210 refers to a through hole opened on the support partition 221, which can be circular or square, and is used to provide space for the installation of the panel bracket 31 and the lamp holder 1. The second through hole 9010 refers to a through hole opened on the encoder circuit board assembly 9, which can be a hole arranged corresponding to the first through hole, and is used together with the first through hole 2210 to provide installation space for connecting the panel assembly 3 and the lamp holder 1. The first fixing structure 311 refers to the connecting component on the panel bracket 31, which can be screw holes or snap-fit ​​structures, and is used to form a mechanical connection with the second fixing structure on the lamp holder. The second fixing structure 111 refers to the connecting component on the lamp holder, which can be studs or slot structures, and is used to directly bear the installation load of the panel assembly. The relatively movable setting means that a gap is maintained between the panel assembly 3 and the inner wall of the knob drive part 23 and the support partition 221, or a sliding fit is adopted, which can be achieved by reserving an assembly gap, and is used to eliminate mechanical interference during knob operation.

[0052] Specifically, the first through hole 2210 on the support partition 221 and the second through hole 9010 on the encoder circuit board assembly 9 form a vertically penetrating mounting channel, through which the panel bracket 3 is connected to the second fixing structure 111 on the lamp holder 1. For example, refer to Figure 3 As shown, when the first fixing structure 311 is a screw hole, the screw 312 passes through the first through hole 2010 and the second through hole 9010 and is screwed into the stud of the lamp holder 1 (i.e., the second fixing structure), directly fixing the panel bracket 3 to the lamp holder 1 body. During this process, the knob drive unit 23 and the support partition 221 only serve as external wrapping structures for the panel assembly 3 and do not participate in the transmission of axial force. The gap between the panel assembly 3 and the knob drive unit 23 and the support partition 221 allows the panel assembly 3 to remain stationary when the knob bracket rotates, avoiding operating resistance caused by friction.

[0053] Through the above technical solution, this embodiment achieves stable installation of the panel assembly 3 within a compact lamp holder structure. During knob operation, there is no mechanical interference between the panel assembly 3 and the knob bracket 2, ensuring a uniform and smooth product appearance. The panel assembly 3 directly bears the force through the lamp holder 1 body, avoiding positioning offset problems caused by deformation of the knob bracket 2 under stress. The relatively movable design further improves the smoothness of knob operation while reducing the requirements for component machining precision.

[0054] This embodiment further proposes that the panel assembly includes a panel bracket 31, an operation panel 32 disposed on one side of the panel bracket 31, a light-guiding silicone 33 disposed on the button hole 313 of the panel bracket 31, and a touch panel 34 disposed on the other side of the panel bracket 31. The panel bracket 31 and the touch panel 34 are bonded together by double-sided adhesive 35.

[0055] Among them, the light-guiding silicone 33 refers to an elastic silicone material with light-guiding properties, which can be made by molding semi-transparent silicone. Covering the button holes, it can evenly conduct backlight and provide physical pressure feedback. The panel bracket 31 is a supporting structure that supports the operation panel 32 and the touchpad 34. It can be made by injection molding of a plastic part, with mounting and positioning structures on its edges for component alignment. The double-sided adhesive 35 is a thin layer material with adhesive function, which can be made by using acrylic foam tape. Its bonding to the panel bracket and touchpad eliminates the space required for traditional screw fixing. The touchpad 34 is a capacitive touch sensing module, which can be made by integrating a touch sensor on a printed circuit board, forming a two-way operating interface with the operation panel.

[0056] Specifically, the panel bracket 31 serves as the core support layer, integrating the operation panel 32 and touchpad 34 on both axial sides to form a bidirectional operation structure. The operation panel provides tactile feedback through physical button holes 313, with light-guiding silicone 33 embedded within the button holes 313 to achieve uniform backlight diffusion and waterproof sealing. The touchpad 34 is directly bonded to the back of the panel bracket 31 using double-sided adhesive 35, eliminating the need for support through the support partition 221 and ensuring the independence of the panel assembly 3. When the components are stacked axially, the elastic compression of the light-guiding silicone 33 compensates for assembly tolerances, and the flexible adhesion of the double-sided adhesive allows for slight deformation of the touch layer to improve operational sensitivity. The positioning structure at the edge of the panel bracket 31 matches the corresponding features inside the lamp holder, ensuring precise alignment of the multi-layer components within a compact space.

[0057] Compared to existing technologies, traditional solutions use a back shell to fix the touch panel 34, light-shielding cotton 36, and other structures. However, in this embodiment, the knob bracket 2 does not provide back shell support, and the double-sided adhesive bonding method eliminates the need for a back shell structure while ensuring that the panel assembly 3 has a sufficiently thin thickness. Existing light guide structures often use a separate design of independent light guide plates and silicone buttons. This solution integrates the light guide and button functions into a single silicone component, reducing the number of parts and assembly steps. Conventional touch panels 34 only have a single-layer operation interface. This solution integrates physical buttons and a touch layer bidirectionally through the panel bracket 31, achieving dual interaction modes within the same space.

[0058] Through the above technical solutions, this application integrates physical buttons and touch functions in an axially stacked structure. The light-guiding silicone simultaneously solves the problems of backlight diffusion and button sealing, while double-sided adhesive bonding replaces the back shell fixing method, reducing structural thickness. The layered layout of the operation panel and touchpad avoids functional interference, the positioning structure of the panel bracket ensures the assembly accuracy of the multi-layer components within a compact space, and the flexible adhesive design of the touch layer improves operational sensitivity.

[0059] This embodiment further proposes to provide a light-blocking cotton 36 between the touch panel 34 and the support partition 221.

[0060] Among them, the light-blocking cotton 36 refers to a flexible light-blocking layer made of black foam material, specifically polyurethane foam, with a matte texture on the surface to enhance light absorption performance. This material is processed into a ring-shaped structure that matches the shape of the support partition through a die-cutting process, covering the assembly gap between the edge of the touch panel and the support partition during installation.

[0061] Specifically, the light-blocking cotton is sandwiched between the touchpad and the support partition to form a physical isolation layer. Its flexibility allows for compensation of tolerances between the panel assembly and the knob drive unit during assembly. When light is generated by the light-guiding silicone or LED light source inside the control panel, the light-blocking cotton blocks the light from propagating towards the touchpad through absorption and scattering, preventing stray light from penetrating the touchpad surface and forming interference signals. Simultaneously, the ring-shaped structure of the light-blocking cotton surrounds the panel assembly, blocking external ambient light from entering the back of the touchpad through the gap between the support partition and the panel bracket, eliminating interference from ambient light fluctuations on the capacitive touch sensor. The contact surface between the light-blocking cotton and the support partition forms an elastic support, absorbing mechanical vibration energy when the knob is rotated, reducing the risk of accidental touches caused by vibration transmission to the touchpad.

[0062] Through the above technical solutions, this application effectively prevents the dual interference of stray light from the internal light source and ambient light on the touch panel, significantly reducing the probability of accidental touch and improving the touch response accuracy; the elastic support characteristics of the light-shielding cotton reduce the impact of vibration on the touch panel during knob operation and extend the service life of the touch components; the ring-shaped light-shielding structure does not require changes to the original assembly process and achieves synergistic optimization of optical and mechanical performance in a compact space.

[0063] like Figure 6 As shown, this embodiment further proposes that the edge of the panel bracket 31 is provided with a first foolproof mounting structure 317, and the touch panel 34, the light-blocking cotton 36 and the double-sided adhesive 35 are respectively provided with a second foolproof mounting structure (341, 361, 351).

[0064] The first foolproof mounting structure 317 refers to a physical limiting feature set on the edge of the panel bracket 31, which can be implemented using an asymmetrical protrusion or groove structure, limiting the installation direction of the component through shape differences. The second foolproof mounting structure (341, 361, 351) refers to a corresponding feature that complements the first foolproof mounting structure, which can be implemented using a groove corresponding to a protrusion or a protrusion corresponding to a groove, ensuring assembly uniqueness through the irreversibility of geometric shape.

[0065] Specifically, the asymmetrical protrusions on the edge of the panel bracket 31 form a unique matching relationship with the grooves on the edge of the touchpad. When the two come into contact, assembly can only be completed when the protrusions and grooves are perfectly aligned. The second foolproof mounting structures (341, 361, 351) on the light-blocking cotton 36 form a nested relationship with the protrusions of the panel bracket. When multiple components are stacked, positional misalignment is eliminated through layer-by-layer matching. During installation, if the component orientation is incorrect or the position is misaligned, interference between the foolproof structures will directly prevent the assembly action, forcing the operator to readjust.

[0066] In some specific embodiments, the first foolproof mounting structure 317 can be a rectangular boss, and the second foolproof mounting structure can be a corresponding rectangular notch; or the first foolproof mounting structure can be an L-shaped buckle, and the second foolproof mounting structure can be an L-shaped slot. The second foolproof mounting structure of the light-blocking cotton can be set as a through hole with the same shape as the protrusion of the panel bracket, and it needs to pass through both the protrusion and the through hole during assembly.

[0067] Compared to existing technologies, traditional lighting panel assemblies rely on manual visual alignment, which can easily lead to misalignment in compact structures due to limited operating space. This solution uses physical limiting features to forcibly guide the correct installation path, achieving zero-error assembly without relying on operator experience, while also eliminating component wear caused by repeated trial and error.

[0068] Through the above technical solution, this application effectively prevents the touch panel and the light-blocking cotton from being reversed in direction or shifted in position during the installation process, ensuring the precise stacking of multi-layer components in a limited space, reducing light path leakage or touch failure caused by assembly errors, and improving product assembly efficiency and yield.

[0069] like Figure 1 As shown, this application further proposes a lamp, including a lamp holder 1 and a light-emitting module 5 connected to the lamp holder 1, and also includes a lamp panel structure 100, which is disposed on the lamp holder 1.

[0070] The luminaire panel structure 100 refers to a composite component integrating dimming control functions. Specifically, it can be implemented using a modular design that includes a knob drive unit and an encoder circuit board, and achieves compact assembly with the lamp holder through a built-in snap-fit ​​mechanism. The lamp holder refers to the support structure that supports the core components of the luminaire. Specifically, it can be implemented using an injection-molded housing with a stud positioning structure, and achieves detachable connection with the panel assembly through a standardized interface.

[0071] Specifically, the lamp panel structure is embedded inside the lamp holder via a snap-fit ​​connection, and the knob drive unit and encoder circuit board form a spatially interlocking mechanical linkage structure. The panel assembly achieves planar positioning through the threaded engagement of screw holes and lamp holder studs, and an operating gap is maintained between the inner wall of the knob drive unit and the panel assembly. A light-blocking liner is placed between the touch panel and the support structure to eliminate light interference through physical isolation.
