Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a lamp. Background Technology

[0002] Lighting fixtures, such as tri-proof lights, emergency lights, and ceiling lights, generally include a lamp housing and a lamp panel housed within the housing. The lamp housing comprises an upper shell and a light-transmitting lampshade. The bottom of the upper shell is open, while the top of the light-transmitting lampshade is open. The two are fastened together to form a cavity for housing the lamp panel. The lamp panel generally includes a support plate and a light strip mounted on the bottom of the support plate. Traditionally, the lamp panel and lamp housing are installed by direct screw fixing, or by using clips for fixing and limiting. For example, the applicant's earlier application CN221483493U, "A Tri-proof Light," discloses such an installation structure, specifically: a protruding buckle protruding towards the interior of the cavity is provided on the side wall of the transparent lampshade, and a limiting step is formed in the area below the protruding buckle. When the lamp panel is placed into the receiving chamber of the light-transmitting lampshade from top to bottom, the lamp panel can pass over the protrusion and rest on the aforementioned limiting step. After being placed in place, the positioning edge of the lamp panel can abut against the side wall of the receiving chamber, and the protrusion presses against the top of the side of the lamp panel to achieve upper limiting, preventing the lamp panel from easily coming off upwards and ensuring the stability of the lamp panel installation.

[0003] However, the lighting fixture described in the aforementioned patent application CN221483493U has certain shortcomings. The disassembly and maintenance of the lamp panel presents significant obstacles. When replacing the lamp panel or inspecting the internal wiring, specialized tools must be used to pry open the latching mechanism between the lamp panel and the latch. This operation not only requires professional personnel but is also highly susceptible to scratches and damage to the light-transmitting lampshade or lamp panel during the prying process, and may even cause the plastic latch to break and fail. Furthermore, for special scenarios such as tri-proof lights and emergency lights requiring rapid lamp panel replacement, the traditional structure cannot be disassembled and reassembled manually, severely limiting maintenance efficiency.

[0004] Therefore, the existing lighting fixtures still need further improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a lighting fixture that can effectively improve the disassembly and assembly efficiency of the lamp panel assembly and facilitate subsequent maintenance, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a lamp, comprising:

[0007] A light-transmitting lampshade with an opening at the top;

[0008] The lamp panel assembly is installed in the light-transmitting lamp cover and includes a support plate and a light source disposed on the support plate;

[0009] The inner wall of the light-transmitting lampshade has a stepped portion for the outer periphery of the support plate to rest on. The inner wall of the light-transmitting lampshade has an outwardly protruding limiting protrusion, which includes a protrusion portion located above the stepped portion. The support plate has a vertically penetrating limiting slot in the area adjacent to its outer periphery. After the limiting protrusion of the light-transmitting lampshade passes through the limiting slot, it moves a certain distance or rotates a certain angle relative to the support plate in a straight line. The peripheral edge of the limiting slot of the support plate or the edge of the support plate is then limited between the protrusion portion and the stepped portion.

[0010] The aforementioned "stepped section" refers to the stepped structure on the inner wall of the lampshade, which is used for supporting and positioning the load-bearing plate. It can be a ring-shaped flange or a section of boss.

[0011] As an improvement, the limiting protrusion is disposed on the stepped portion, and the limiting protrusion further includes an extension portion extending upward from the stepped portion, the protrusion portion protruding laterally from the extension portion; or

[0012] The limiting protrusion is located on the inner wall of the light-transmitting lampshade in the area above the step, and the limiting protrusion extends toward the inside of the light-transmitting lampshade.

[0013] The two types of limiting protrusions mentioned above can be well adapted to the installation of lampshades or carrier plates of different shapes, expanding adaptability and meeting the fixing needs of diverse lighting fixture structures.

[0014] As an improvement, the light-transmitting lampshade is elongated, and the lamp panel assembly is also elongated to match. After the limiting protrusion of the light-transmitting lampshade passes through the limiting slot, it moves a certain distance relative to the support plate along the length of the support plate. The peripheral edge of the limiting slot on the support plate then limits the protrusion between the protrusion and the step. The linear movement direction of the limiting protrusion and the limiting slot to achieve the limiting engagement is set along the length of the support plate, which better utilizes the allowable design margin for movement between the support plate and the lampshade in the length direction, ensuring uniform force distribution and precise positioning of the elongated structure.

[0015] As an improvement, the limiting latch includes a clearance opening and a retaining opening arranged sequentially along the length of the support plate. The clearance opening and the retaining opening are connected. When the limiting protrusion of the light-transmitting lampshade passes through the clearance opening and moves relative to the support plate along the length of the support plate to the position of the retaining opening, the peripheral edge of the retaining opening is limited between the protrusion and the step. The limiting latch, with its clearance opening and retaining opening structure, achieves a one-step installation of "insertion followed by translation," improving assembly efficiency.

[0016] To avoid lateral shifting or shaking after the support plate is assembled, the cross-section of the extension of the limiting protrusion is flat, and the width direction of the extension is consistent with the length direction of the light-transmitting lampshade. The retaining opening is a strip-shaped opening that matches the extension.

[0017] To simplify the structure of the limiting buckle and ensure the reliable positioning of the bearing plate by the buckle portion, the buckle portion of the limiting buckle protrudes from the extension portion along the width direction of the light-transmitting lampshade towards the inside or outside of the light-transmitting lampshade.

[0018] To further ensure the secure installation of the support plate, the stepped portion of the light-transmitting lampshade is adjacent to the top opening of the lampshade and is an annular stepped portion extending circumferentially along the top opening of the light-transmitting lampshade. At least two limiting protrusions are arranged sequentially along the extending direction of the annular stepped portion. The annular stepped portion, in conjunction with multiple limiting protrusions, achieves uniform circumferential locking of the support plate, improving the stability of the overall installation structure.

[0019] As an improvement, the light-transmitting lampshade includes a lampshade body and an annular retaining edge extending upward from the top opening of the lampshade body and located around the annular stepped portion, with the supporting plate situated within the area defined by the annular retaining edge. The annular retaining edge of the light-transmitting lampshade forms a protective boundary, limiting the displacement range of the supporting plate and blocking external interference, and can also be used for mounting with the upper housing of the lamp fixture.

[0020] Considering that the support plate is mostly made of metal, and operators have direct contact with its edges, there is a risk of being cut or scratched, which requires complete disassembly during maintenance, making operation inconvenient. Therefore, in the optional solution, a first protective plate is also included, which is detachably connected to at least one of the two ends of the support plate along its length. The first protective plate is connected to the lampshade by fasteners.

[0021] To achieve a detachable connection between the support plate and the first protective plate, the first protective plate includes a horizontally arranged cross plate, a surrounding plate extending downward from the cross plate, and an elastic buckle extending laterally from the surrounding plate. The elastic buckle is located below the cross plate. The support plate has a limiting recess. The end of the support plate can be inserted between the elastic buckle and the cross plate, and the elastic buckle is engaged in the limiting recess to restrict the movement of the support plate relative to the first protective plate.

[0022] To facilitate the disassembly and replacement of the light source, the light source is a long strip of light that extends along the length of the support plate. The first protective plate also has a first clearance notch on its surrounding wall for the light strip to pass through along its length. With the first clearance notch on the surrounding wall of the first protective plate, the first protective plate does not need to be removed from the support plate, while the light strip can be removed by passing through the first clearance notch, thus improving maintenance efficiency.

[0023] To further facilitate operators in handling the support plate and enabling quick assembly and disassembly of the support plate, the first protective plate also has a first handle for gripping and a connecting plate extending from the enclosure towards the side opposite to the horizontal plate. The connecting plate is connected to the lampshade by fasteners.

[0024] Considering that the support plate is mostly made of metal, operators have direct contact with its edges, posing a risk of cuts or scratches, and maintenance requires complete disassembly, which is inconvenient. Therefore, in another optional solution, a second protective plate is also included, connected to at least one of the two ends along the length of the support plate. The second protective plate includes a protective plate body and a flip-up baffle rotatably connected to the protective plate body. The protective plate body is installed on the back of the support plate, and the flip-up baffle has at least a first use state and a second use state as its position relative to the protective plate body changes.

[0025] In the first usage state, the flip baffle and the protective plate body are spliced ​​together to form a complete plate body, and the flip baffle is restricted from upward deflection by the protective plate body and the protective plate body body through a buckle structure, and the flip baffle rests on the step part of the light-transmitting lampshade;

[0026] In the second usage state, the flip baffle flips upward relative to the protective plate body and is set at an angle to the support plate, and the flip baffle serves as a second handle for gripping.

[0027] In the above-mentioned "back side of the carrier plate", "back side" refers to the side of the carrier plate that is away from the light source installation position. Generally, it refers to the upper side of the carrier plate. The upper side of the carrier plate is usually also used to install the driver power supply, emergency kit module, etc.

[0028] The flip-up baffle serves as both protection and a handle. In the first use state, it extends the length of the second protective plate to rest on the step of the lampshade. In the second use state, it can be used as a second handle for gripping, achieving multi-functional integration and optimizing the user experience.

[0029] To further prevent operators' hands from touching the edge of the support plate, the bottom of the protective plate body has a protective guard that extends downward and is located around the perimeter of the end of the support plate.

[0030] To facilitate the disassembly and replacement of the light source, the light source is a long strip of light that extends along the length of the support plate. The protective edge also has a second clearance notch for the light strip to pass through along its length. With this second clearance notch on the protective edge, the second protective plate does not need to be removed from the support plate; the light strip can be removed by passing through the second clearance notch, thus improving maintenance efficiency.

[0031] Considering that in the first usage state, the protective panel body and the flip-up baffle form a complete panel structure, the flip-up baffle is inconvenient to operate and lacks a clear point of force application. Therefore, in the first usage state, the flip-up baffle also has an upwardly extending operating panel, which defines a hand-holding recess for the user's fingers to insert. The hand-holding recess provides space for finger operation, reduces flipping resistance, and improves ease of operation.

[0032] To achieve locking between the protective panel body and the flip-up baffle in the second usage state, the operating plate of the flip-up baffle has an outwardly protruding limiting buckle on the side facing the protective panel body. The edge of the protective panel body has an upwardly recessed, protruding shape that extends above the top surface of the protective panel body. In the first usage state, the limiting buckle is positioned at the bottom of the edge of the pressed shape. The limiting buckle cooperates with the pressed edge to form a mechanical lock, constituting a buckle structure for limiting the upward deflection of the flip-up baffle, ensuring the stability of the flip-up baffle in the first usage state.

[0033] Considering the messy wiring harness of the light source and the potential for cable wear or installation difficulties due to improperly designed wiring holes, some optional solutions define a first wiring hole on the protective plate body, the flip-up baffle, or between the protective plate body and the flip-up baffle for the wiring harness connected to the light source to pass through. By defining a clear wiring path with the first wiring hole, the cable passes directly from the light source through the protective plate body or the flip-up baffle, avoiding interference with other internal components of the luminaire and reducing the risk of wear. During the design process, the location of the wiring hole (protective plate body, flip-up baffle, or between the two) can be flexibly selected according to actual installation needs and the wiring harness position to adapt to different installation scenarios, improving design freedom and practicality.

[0034] The edge of the molded protective plate body is provided with a non-closed hole with an opening facing the operating plate. This non-closed hole is the first wire passage hole, and the handle recess of the operating plate is opposite to the opening of the first wire passage hole.

[0035] The aforementioned "non-closed hole" refers to a hole whose edge is not completely closed during molding, used for wire harness threading, such as a C-shaped notch or a semi-circular opening.

[0036] The open-hole design allows the cable harness to be directly inserted through the side opening without needing to pass through the hole completely, significantly simplifying the wiring process and improving installation efficiency. The open-hole opening faces the handle recess on the control panel, allowing the operator to easily press the cable into the hole and secure it, preventing the cable harness from loosening and maintaining a smooth appearance. In particular, the design of the handle recess facing the cable hole opening expands the operating space for cable harness threading and finger insertion into the handle recess, forming an integrated "operation-threading" design that balances functionality and a user-friendly operating experience.

[0037] As an improvement, the first cable guide hole is located at the edge of the protective plate body, and a second cable guide hole is located at the edge of the support plate for the cable harness connected to the light source to pass through. The second cable guide hole is vertically opposite to the first cable guide hole. The vertically opposite cable guide hole design can prevent the cable from protruding and being exposed relative to the edge of the support plate, thereby improving the utilization of internal space and aesthetics.

[0038] Through the coordinated design of the first wire guide hole, the second wire guide hole, and the non-closed hole, the wiring harness routing is optimized, cable bending is avoided, and a neat appearance is maintained.

[0039] Compared with existing technologies, the advantages of this utility model are as follows: The carrier plate and the light-transmitting lampshade utilize a locking mechanism with a limiting latch and a limiting protrusion. This allows the lamp panel assembly to be locked during installation simply by passing the limiting protrusion through the limiting latch and moving it linearly or rotating it. Disassembly is achieved by reversing the operation, eliminating the need for tools. Compared to traditional pry-type latches, this design allows maintenance personnel to complete disassembly and assembly by hand, making it particularly suitable for scenarios requiring rapid replacement, such as emergency lights, effectively improving maintenance efficiency. Furthermore, the coordinated upper and lower limiting of the stepped portion and the protrusion, combined with the double constraint of the carrier plate edge or the periphery of the limiting latch, ensures the stability of the lamp panel installation and eliminates the loosening defects of traditional single-point latches.

[0055] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0056] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0057] Example 1

[0058] Figures 1-8 A preferred embodiment of the lamp fixture of this utility model is shown. The lamp fixture includes a lamp housing and a lamp panel assembly disposed within the lamp housing. The lamp housing includes a light-transmitting lampshade 20 with an open top and an upper housing 11 fastened to the open top of the light-transmitting lampshade 20. The connection structure between the light-transmitting lampshade 20 and the upper housing 11 can adopt existing technology, which will not be described in detail here.

[0059] The lamp housing is generally elongated, and the lamp panel assembly is also elongated to match. The lamp panel assembly is detachably installed inside the light-transmitting lampshade 20. The lamp panel assembly includes an elongated support plate 3 and LED light strips arranged along its length. The support plate 3 is generally made of metal, such as iron. The light strips are installed on the front (bottom) of the support plate 3, while the back (top) of the support plate 3 typically houses a driver power module, an emergency power module, and a sensor module. These are all existing technologies and will not be described in detail further.

[0060] See Figure 5 The inner wall of the light-transmitting lampshade 20, near the top opening, has a circumferentially extending annular stepped portion 23. This annular stepped portion 23 is an annular flange used to support the support plate 3 of the lamp panel assembly. The light-transmitting lampshade 20 includes a lampshade body 21 and an annular retaining edge 22 extending upward from the top opening of the lampshade body 21. The annular retaining edge 22 is located around the annular stepped portion 23. The annular retaining edge 22 defines the mounting area of ​​the support plate 3, preventing lateral displacement of the support plate 3.

[0061] Multiple limiting protrusions 24 are provided on the inner wall of the light-transmitting lampshade 20, corresponding to the inner side of the annular step portion 23. For example... Figure 5As shown, four limiting protrusions 24 are spaced apart on both sides of the annular step portion 23 and the light-transmitting lampshade 20 along their length direction. Each limiting protrusion 24 includes a flat extension portion 241 extending upward from the annular step portion 23 and a protruding protrusion portion 242 protruding inward from the extension portion 241 along the width direction of the light-transmitting lampshade 20. The width direction of the extension portion 241 is consistent with the length direction of the light-transmitting lampshade 20, and its cross-section is rectangular to fit the limiting slot 31 structure of the support plate 3.

[0062] Four limiting slots 31 are provided on the outer periphery of the support plate 3. In this embodiment, the limiting slots 31 are closed openings. Each limiting slot 31 consists of a clearance opening 311 and a retaining opening 312 arranged sequentially along the length direction of the support plate 3. The clearance opening 311 and the retaining opening 312 are connected. The clearance opening 311 is a large through hole, and the retaining opening 312 is a strip-shaped through hole that matches the cross-section of the extension 241. During installation, the clearance opening 311 of the support plate 3 is aligned with the limiting protrusion 24 of the light-transmitting lampshade 20, and the support plate 3 is placed downward so that the limiting protrusion 24 passes through the clearance opening 311. Then, the support plate 3 is pushed along the length direction of the support plate 3 so that the extension 241 of the limiting protrusion 24 slides into the retaining opening 312. At this time, the peripheral edge of the retaining opening 312 is limited between the protrusion 242 and the step 23, thereby achieving the upper and lower limiting of the support plate 3.

[0063] See Figures 6-8 Considering that the support plate 3 is mostly made of metal, and operators have direct contact with its edges, there is a risk of being cut or scratched, requiring complete disassembly for maintenance, which is inconvenient. Therefore, the lamp panel assembly also includes a first protective plate 4. The first protective plate 4 is detachably installed at both ends of the support plate 3 along its length. The first protective plate 4 includes a horizontally extending cross plate 41, a surrounding plate 42 extending downward from the edge of the cross plate 41, and an elastic buckle 421 extending horizontally from the side of the surrounding plate 42. The cross plate 41 can be abutted against the top of the end of the support plate 3, and the elastic buckle 421 is located below the cross plate 41, specifically acting at the bottom of the end of the support plate 3, engaging with the limiting notch 33 opened on the support plate 3. The surrounding plate 42 of the first protective plate 4 is designed to have the same shape as the end of the support plate 3, such as both being designed as an outwardly convex arc shape. After the first protective plate 4 and the bearing plate 3 are installed in place, the corresponding side wall of the enclosure 42 abuts against the end of the bearing plate 3, together with the aforementioned elastic buckle 421, restricting the relative movement of the first protective plate 4 and the bearing plate 3, ensuring the reliability of the connection between the two.

[0064] The front of the support plate 3 has a groove extending along its length, with two limiting buckles on either side of the groove. The LED light strip can be placed into the groove along its length and held in place by the limiting buckles at the bottom. The surrounding plate 42 of the first protective plate 4 also has a first clearance notch 45 for the LED light strip to pass through. The light strip can be slidably removed along the notch without disassembling the first protective plate 4. Furthermore, a connecting plate 44 is provided on the outer side of the surrounding plate 42 of the first protective plate 4. The connecting plate 44 is also horizontally arranged and extends towards the side opposite to the horizontal plate 41. The connecting plate 44 is fixed to the light-transmitting lampshade 20 by fasteners 46 such as screws, enhancing stability.

[0065] To further facilitate operators in picking up or moving the support plate 3 and to enable quick assembly and disassembly of the support plate 3, the first protective plate 4 also has a first handle 43 for gripping. The first handle 43 can be an arc-shaped handle that arches upward from the top of the horizontal plate 41 of the first protective plate 4.

[0066] Example 2

[0067] Figures 9-15 Another preferred embodiment of the lamp of this utility model is shown. The difference between this embodiment and embodiment 1 is that the limiting protrusion 24 provided on the light-transmitting lampshade 20, the limiting opening opened on the support plate 3, and the protective plate provided at the end of the support plate 3 are different.

[0068] Specifically, the location of the limiting protrusion 24 in this embodiment differs from that in Embodiment 1. The limiting protrusion 24 of the light-transmitting lampshade 20 is not located on the step portion 23, but rather on the inner wall of the light-transmitting lampshade 20, corresponding to the inner wall region above the step portion 23. The limiting protrusion 24 is a protruding structure protruding towards the interior of the light-transmitting lampshade 20. The entirety or part of this limiting protrusion can serve as a non-closed hole recessed into the limiting slot 31 of the supporting plate 3 from the edge of the supporting plate 3 towards the center of the supporting plate 3. During installation, the limiting protrusion 24 needs to be aligned with the limiting slot 31, and the supporting plate 3 should be extended along its length and moved linearly so that the limiting protrusion 24 abuts against the top of the edge of the supporting plate 3, achieving locking. Considering that the small distance between the limiting protrusion 24 and the step portion 23 would increase the processing difficulty of the lampshade, and that the thickness of the support plate 3 is relatively thin, the edge of the support plate 3 can be constructed with an upward-folded edge. The height of the folded edge can be designed according to actual needs. In this way, when installing the support plate 3, the limiting protrusion 24 can rest against the top of the folded edge of the support plate 3. See details. Figure 11 .

[0069] See Figures 11-14In this embodiment, a second protective plate 5 is used instead of the first protective plate 4. Specifically, the second protective plate 5 is installed at the end of the support plate 3 along its length. In this embodiment, the second protective plate 5 is installed only at one end of the support plate 3. The second protective plate 5 includes a protective plate body 51 and a rotatably connected flip-over baffle 52. The protective plate body 51 is a horizontally extending plate body, which is fixed to the back (i.e., the upper surface) of the support plate 3 by screws. Both the front and rear sides of the protective plate body 51 have outwardly protruding shaft portions that extend in the same direction, and the extension direction of the shaft portions is consistent with the width direction of the support plate 3. The flip-over baffle 52 is an arc-shaped plate body, and its two ends are provided with shaft holes that cooperate with the aforementioned shaft portions to realize the vertical deflection of the flip-over baffle 52 relative to the protective plate body 51.

[0070] The bottom of the protective plate body 51 has a downwardly extending protective flange 510 located around the end periphery of the support plate 3. The protective flange 510 wraps around the end edge of the support plate 3 to prevent scratches. The protective flange 510 has a second clearance notch 511, through which the LED light strip can be pulled out and replaced. This has the same function as the first clearance notch 45 in Embodiment 1, and will not be described again.

[0071] The flip-up baffle 52 has at least a first use state and a second use state as its position relative to the protective plate body 51 changes, as follows: Figure 11 and Figure 13 As shown.

[0072] In its first usage state, the flip-up baffle 52 and the protective panel body 51 are horizontally aligned and spliced ​​together to form a complete panel. The bottom of the flip-up baffle 52 rests on the annular step portion 23 of the light-transmitting lampshade 20. The supporting plate 3 itself can limit the downward deflection of the flip-up baffle 52. The protective panel body 51 and the protective panel body 51 are connected by a snap-fit ​​structure to limit the upward deflection of the flip-up baffle 52.

[0073] Considering that in the first usage state, the protective plate body 51 and the flip baffle 52 are spliced ​​together to form a complete plate structure, the flip baffle 52 is inconvenient to operate and lacks a clear point of force application. Therefore, in the first usage state, the flip baffle 52 also has an upwardly extending operating plate 521. The operating plate 521 defines a hand-holding recess 5210 for the user's fingers to insert into. In this embodiment, the hand-holding recess 5210 is a through-hole that penetrates the operating plate 521. The hand-holding recess 5210 provides space for finger operation, reduces flipping resistance, and improves operational convenience.

[0074] The operating plate 521 of the flip baffle 52 is provided with an outwardly protruding limiting buckle 5211. When the flip baffle 52 is in its first use state, the limiting buckle 24 protrudes towards the side where the protective plate body 51 is located. Specifically, the limiting buckle 24 is an inverted buckle structure with a guide slope and a backstop surface. The edge of the protective plate body 51 is provided with an upwardly recessed molding 513, which is higher than the top surface of the protective plate body 51. When the flip baffle 52 is rotated downward to its final position, the limiting buckle 5211 can pass over the edge of the molding 513 and abut against the bottom edge of the molding 513, restricting the flip baffle 52 from flipping upward. When it is necessary to flip the baffle 52 upward, the finger can be used to hold the handle recess 5210 of the operating plate 521 and apply force to the flip baffle 52 along the length direction of the bearing plate 3, so that the limiting buckle 5211 disengages from the edge of the molding 513 and the flip baffle 52 is lifted upward. In the second use state, the flip baffle 52 flips upward 90° (or other angles, of course) and becomes perpendicular to the support plate 3, forming a second handle for gripping.

[0075] The protective plate body 51 has a C-shaped non-closed hole (i.e., a first wire-passing hole 514) with an opening facing the operating plate 521 on its pressed 513 edge. A second wire-passing hole 32 is provided at a corresponding position on the edge of the support plate 3. The first wire-passing hole 514 and the second wire-passing hole 32 are vertically opposite each other. After the wire harness is led out from the end of the LED light strip, it passes through the second wire-passing hole 32 and the first wire-passing hole 514 in sequence, and is routed along its length on the top of the support plate 3, connecting to modules such as the drive power supply located on the top of the support plate 3. The non-closed hole design allows the wire harness to be directly inserted from the side opening without needing to be fully penetrated, significantly simplifying the wiring operation and improving installation efficiency.

[0076] In this embodiment, the opening of the non-closed hole on the molding 513 faces the handle recess 5210 of the operation plate 521. This structural design allows the operator's fingers to easily press the cable into the hole and fix it, preventing the cable harness from coming loose, while maintaining a flat appearance. On the other hand, the design of the handle recess 5210 facing the opening of the cable hole expands the operating space for cable harness threading and fingers to enter the handle recess, forming an "operation-threading" linkage design that balances functionality and user-friendly operation.

[0077] Based on the above embodiments, other embodiments can be obtained by replacing and improving the relevant technical features. For example, the step portion 23 of the light-transmitting lampshade 20 is a partially designed step, similar to a boss rather than a ring structure. The step can be set in multiple segments to provide sufficient support for the support plate 3. As another example, after the limiting protrusion 24 of the light-transmitting lampshade 20 passes through the limiting slot 31, it can also be rotated relative to the support plate 3 by a certain angle, so that the peripheral edge of the limiting slot 31 of the support plate 3 is limited between the protrusion portion 242 and the step portion 23. The axis of rotation between the light-transmitting lampshade and the support plate is a straight line that is approximately perpendicular to the support plate, generally a vertical straight line. This structure is suitable for circular lampshades and can achieve quick assembly and disassembly through rotation.
