Description

Technical Field

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

[0002] With the rapid development of LED lighting technology and the increasing demand for aesthetically pleasing lighting products, the structural design and appearance quality of LED lamps have become crucial factors influencing product competitiveness. Modern LED lamps are typically composed of multiple components, including inner frames, outer frames, and light-transmitting housings. The fit and relationship between these components directly affect the lamp's appearance, structural stability, and lifespan.

[0003] In traditional LED lighting design, the outer frame and inner frame are typically connected using a simple fitting or snap-fit ​​method. Specifically, the outer frame is directly fitted onto the outer periphery of the inner frame, and the two are connected through basic geometric fit. However, this traditional connection method has a prominent technical problem: noticeable gaps easily form between the outer and inner frames, severely affecting the aesthetics and overall integrity of the lighting fixture.

[0004] Specifically, due to manufacturing tolerances, assembly errors, and the effects of thermal expansion and contraction of materials, traditional outer and inner frames often cannot achieve a perfect fit, resulting in visible gaps at the joint. These gaps not only disrupt the integrated appearance of the lamp, making the product look rough and of lower quality, but can also become channels for dust, moisture, and other foreign objects to enter, affecting the lamp's protective performance and lifespan. Furthermore, the presence of these gaps reduces the stability of the connection, potentially leading to safety hazards such as loosening or detachment of components during long-term use. Utility Model Content

[0005] This utility model provides a lamp housing and a lamp fixture. The lamp housing can effectively solve the problem of the gap between the outer frame and the inner frame, realize the seamless fit between the outer frame and the inner frame, and improve the appearance and overall quality of the lamp fixture.

[0006] This utility model provides a lamp housing, comprising: an inner frame connected to the top cover of a lamp; a middle frame fitted onto the outer periphery of the inner frame; and an outer frame fitted onto the outer periphery of the inner frame. The outer frame includes: a first frame located outside the middle frame and fitting against the outer periphery of the middle frame; an extension structure disposed inside the first frame and extending toward the inner frame, the extension structure and the middle frame being sequentially arranged along the axial direction of the inner frame; and a bonding plate disposed at the end of the extension structure away from the first frame, the bonding plate being connected to the inner frame and fitting against the outer periphery of the inner frame.

[0007] Optionally, the extension structure includes: a first connecting plate, the two ends of which are respectively connected to the first frame and the bonding plate; and a second connecting plate, which is spaced apart from the first connecting plate along the axial direction of the first frame, the two ends of which are respectively connected to the first frame and the bonding plate.

[0008] Optionally, the bonding plate is provided with a mounting part, which is located between the first connecting plate and the second connecting plate, and the inner frame is connected to the mounting part.

[0009] Optionally, the intermediate frame includes a housing, with a light groove provided at one end of the housing facing the first connecting plate, and the housing is made of a light-transmitting material; the light housing also includes a first light strip, which is disposed on the first connecting plate and located in the light groove.

[0010] Optionally, the intermediate frame includes a light-transmitting strip, and an installation space is formed between the bonding plate and the first frame. The lamp housing also includes a second light strip, which is disposed on the second connecting plate and located within the installation space. The light-transmitting strip is installed within the installation space and is made of elastic material to enclose the installation space.

[0011] Optionally, the first frame and the bonding plate are respectively provided with slots on opposite sides, and the light-transmitting strip has a snap-fit ​​part that snaps into the slot.

[0012] Optionally, the light-transmitting strip has a sealing contact portion that abuts against the outer peripheral surface of the inner frame.

[0013] Optionally, the inner frame has a ring structure, and the bonding plate has a ring structure and is bonded to the outer periphery of the inner frame.

[0014] Optionally, the inner frame is made of cast iron and the outer frame is made of aluminum alloy profile.

[0015] Secondly, this utility model provides a lamp, including: a top cover; the aforementioned lamp housing, wherein the inner frame of the lamp housing is connected to the top cover.

[0016] The lamp housing provided by this utility model fundamentally solves the technical problem of gaps between the outer and inner frames in the prior art by setting an extension structure in the outer frame and configuring a bonding plate to fit against the outer peripheral surface of the inner frame. In traditional lamp designs, the outer frame is usually directly fitted onto the outside of the inner frame, and the two are connected by basic geometric fit. Due to manufacturing tolerances, assembly errors, and the thermal expansion and contraction of materials, this fit inevitably produces visible gaps at the joint between the outer and inner frames. However, the extension structure of this utility model extends from the inside of the first frame and is set towards the inner frame. The bonding plate therein directly forms a bonding relationship with the outer peripheral surface of the inner frame. This design effectively eliminates the gaps between the two independent components in the traditional fitting method. Specifically, the bonding plate of the extension structure can actively fit against the outer peripheral surface of the inner frame, replacing the traditional line or point contact with surface contact, greatly increasing the contact area. Even with certain manufacturing tolerances, the bonding plate can form a tight fit with the outer peripheral surface of the inner frame through its own adaptability, thereby completely eliminating the gap problem that is unavoidable in the traditional fitting method. This seamless fit not only significantly enhances the aesthetics and overall appearance of the lamp, giving the product a high-quality, integrated look, but also effectively prevents dust, moisture, and other foreign objects from entering the lamp's interior through the joint, thus improving the product's protective performance.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments in this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] The following is combined with Figure 1-10 This utility model provides a lamp housing, comprising: an inner frame 1 connected to the top cover 2 of a lamp; a middle frame 3 fitted onto the outer periphery of the inner frame 1; and an outer frame 4 fitted onto the outer periphery of the inner frame 1. The outer frame 4 includes: a first frame 41 located outside the middle frame 3 and fitted to the outer periphery of the middle frame 3; an extension structure 42 disposed inside the first frame 41 and extending toward the inner frame 1, the extension structure 42 and the middle frame 3 being sequentially arranged along the axial direction of the inner frame 1; and a bonding plate 43 disposed at the end of the extension structure 42 away from the first frame 41, the bonding plate 43 being connected to the inner frame 1 and fitted to the outer periphery of the inner frame 1.

[0039] The lamp housing can be a circular structure or a frame structure. After the extension structure 42 of the outer frame 4 is connected to the inner frame 1 by fasteners, the upper part of the first frame 41 surrounds the outer periphery of the middle frame 3, thus limiting the circumferential position of the middle frame 3.

[0040] In this embodiment, by setting an extension structure 42 in the outer frame 4 and configuring a bonding plate 43 to bond with the outer peripheral surface of the inner frame 1, the technical problem of a gap between the outer frame 4 and the inner frame 1 in the prior art is fundamentally solved. In traditional lamp designs, the outer frame 4 is usually directly fitted onto the outside of the inner frame 1, and the two are connected by basic geometric fit. Due to manufacturing tolerances, assembly errors, and the thermal expansion and contraction of materials, this fit inevitably produces a visible gap at the joint between the outer frame 4 and the inner frame 1. However, the extension structure 42 of this utility model extends from the inside of the first frame 41 and is set toward the inner frame 1, and the bonding plate 43 therein directly forms a bonding relationship with the outer peripheral surface of the inner frame 1. This design cleverly eliminates the gap between the two independent components in the traditional fitting method. Specifically, the bonding plate 43 of the extension structure 42 can actively fit against the outer periphery of the inner frame 1, replacing traditional line or point contact with surface contact. This significantly increases the contact area, allowing the bonding plate 43 to form a tight fit with the outer periphery of the inner frame 1 even with certain manufacturing tolerances. This completely eliminates the unavoidable gaps in traditional fitting methods. This seamless fit not only significantly improves the aesthetics and overall appearance of the lamp, giving the product a high-quality integrated effect, but also effectively prevents dust, moisture, and other foreign objects from entering the lamp's interior through the fitting point, improving the product's protective performance. Simultaneously, the fastener connection between the extension structure 42 and the inner frame 1 ensures the reliability and stability of the connection, avoiding the loosening or detachment problems that may occur with traditional simple assembly methods, thus enhancing the stability and lifespan of the entire lamp housing structure. More importantly, this technical solution solves the gap problem through structural design improvements, without relying on excessive manufacturing precision, additional sealing materials or decorative coverings. It maintains the feasibility and economy of the manufacturing process, while avoiding the structural complexity problems brought about by traditional solutions, thus achieving the optimal balance between technical effect and manufacturing cost.

[0041] Specifically, the inner frame 1 serves as the internal support frame of the lamp housing, connecting to the top cover 2 of the lamp and providing structural support for the entire lamp. The intermediate frame 3 is fitted onto the outer periphery of the inner frame 1, serving a function of light transmission or decoration. The outer frame 4 is also fitted onto the outer periphery of the inner frame 1, with the first frame 41 and the outer periphery of the intermediate frame 3 having a clearance fit, ensuring the installation and positioning of the intermediate frame 3. The extension structure 42 is located inside the first frame 41 and extends towards the inner frame 1. Through the bonding plate 43 and bonding to the outer periphery of the inner frame 1, a seamless connection between the outer frame 4 and the inner frame 1 is achieved. The extension structure 42 is connected to the inner frame 1 by fasteners, ensuring the connection's firmness and detachability, facilitating subsequent maintenance and replacement.

[0042] In one specific embodiment, this lamp housing structure is widely used in LED ceiling lights, downlights, and other lighting products. In traditional lamp designs, there are often noticeable gaps between the outer frame 4 and the inner frame 1, affecting the product's aesthetics and integrated appearance. However, the extension structure 42 design of this invention, through the tight fit between the bonding plate 43 and the outer periphery of the inner frame 1, effectively eliminates these gaps, resulting in a seamless, integrated appearance for the lamp and significantly enhancing its quality and aesthetics. Simultaneously, this structural design also improves the lamp's dust and water resistance, extending its lifespan.

[0043] In related technologies, the traditional connection method between the outer frame 4 and the inner frame 1 of a lamp typically employs a simple fitting or snap-fit ​​structure. The outer frame 4 is directly fitted onto the outside of the inner frame 1, resulting in a noticeable seam or gap between the two. The inner frame 1 is generally made of die-cast material to ensure structural strength, while the outer frame 4 is made of aluminum alloy. The poor fit between these two different materials not only affects the product's aesthetics but also makes it easy for dust, moisture, and other foreign matter to enter the lamp, impacting its lifespan and lighting performance. Furthermore, the traditional connection method suffers from poor stability, easily leading to loosening or detachment during long-term use.

[0044] The design, which incorporates an extension structure 42 and a bonding plate 43 that fits snugly against the outer periphery of the inner frame 1, completely solves the splicing gap problem present in traditional technologies. The extension structure 42 extends from the inside of the first frame 41 and faces the inner frame 1. The bonding plate 43 fits tightly against the outer periphery of the inner frame 1, eliminating not only visual gaps but also enhancing structural stability. The extension structure 42 is connected to the inner frame 1 using fasteners, ensuring reliable and maintainable connections. Compared to traditional simple assembly methods, this design offers better structural strength and reliability.

[0045] The inner frame 1 is made of cast iron, while the outer frame 4 is made of aluminum alloy. The cast iron component has relatively stable structural strength, providing basic support for the lamp housing; the outer frame 4 is made of aluminum alloy, which is easy to form, allowing for the manufacture of more complex structures and better decorative effects.

[0046] In some embodiments, the extension structure 42 includes: a first connecting plate 421, the two ends of which are respectively connected to the first frame 41 and the bonding plate 43; and a second connecting plate 422, which is spaced apart from the first connecting plate 421 along the axial direction of the first frame 41, the two ends of which are respectively connected to the first frame 41 and the bonding plate 43.

[0047] In this embodiment, a double-layered support frame structure is formed by axially spacing the second connecting plate 422 from the first connecting plate 421, significantly enhancing the torsional resistance and overall rigidity of the extension structure 42. The second connecting plate 422 and the first connecting plate 421 are axially spaced along the first frame 41, and both ends are connected to the first frame 41 and the bonding plate 43 respectively, forming a stable double-layered radial support system. This double-layered structural design not only improves the axial stability of the extension structure 42 but also provides more space and support points for the installation of subsequent functional components, enhancing the structural reliability of the entire lamp housing during installation and use.

[0048] Specifically, the second connecting plate 422 forms a double-layer support structure that cooperates with the first connecting plate 421. The axial spacing between the two connecting plates gives the extension structure 42 torsional resistance, effectively resisting loads from all directions. The two ends of the second connecting plate 422 are connected to the first frame 41 and the bonding plate 43 respectively, forming a stable frame structure with the first connecting plate 421, greatly enhancing the overall rigidity of the extension structure 42. This double-layer support design also creates a certain space between the first connecting plate 421 and the second connecting plate 422, facilitating the installation and wiring of subsequent functional components. Simultaneously, the double-layer structure provides better load distribution, effectively preventing structural damage caused by localized stress concentration.

[0049] In one specific embodiment, when the luminaire needs to integrate multiple functional components, such as light strips, sensors, and control circuits, the double-layer connecting plate structure provides more installation positions and support points. The first connecting plate 421 can be used to install the main lighting elements, and the second connecting plate 422 can be used to install auxiliary functional components. The space between the two can also be used to arrange connecting lines. This design not only improves the functional integration but also ensures the installation stability of each component. Especially in environments with high vibration, such as automotive lighting or marine lighting applications, the double-layer support structure can effectively resist vibration loads and prevent functional components from loosening or falling off.

[0050] By adding a second connecting plate 422 to form a double-layer support structure, the problem of insufficient torsional resistance in a single-layer structure is effectively solved. The axial spacing of the two connecting plates forms a stable frame structure, significantly improving the torsional resistance and overall stiffness of the extension structure 42. The double-layer structure also provides more space and support points, meeting the needs of multi-functional integration. Compared to the single-layer connecting plate design, the double-layer support structure has better load distribution and structural stability, and can adapt to more complex usage environments and functional requirements.

[0051] In some embodiments, the bonding plate 43 is provided with a mounting part 431, which is located between the first connecting plate 421 and the second connecting plate 422, and the inner frame 1 is connected to the mounting part 431.

[0052] In this embodiment, by providing a mounting part 431 on the bonding plate 43 and limiting its position between the first connecting plate 421 and the second connecting plate 422, the high structural strength of this position, supported by double-layer connecting plates, is fully utilized, achieving optimal connection between the inner frame 1 and the extension structure 42. The mounting part 431, located between the first connecting plate 421 and the second connecting plate 422, is supported by both layers of connecting plates, possessing extremely high structural strength and stability, effectively resisting various loads at the connection point. The connection between the inner frame 1 and the mounting part 431 ensures stress distribution and structural stability at the connection point, preventing deformation or damage to the connection point under stress, significantly improving the reliability of the connection and the durability of the overall lamp housing.

[0053] Specifically, the mounting part 431, as a dedicated connecting structure on the bonding plate 43, is positioned between the first connecting plate 421 and the second connecting plate 422, a location with unique structural advantages. Since both the first connecting plate 421 and the second connecting plate 422 are connected to the bonding plate 43, a double support is formed at the location of the mounting part 431, giving this position higher structural strength and rigidity than other positions. The connection between the inner frame 1 and the mounting part 431 is achieved through fasteners. The connection load is transferred through the mounting part 431 to the first connecting plate 421 and the second connecting plate 422, and then distributed to the first frame 41, forming a good load transfer path. This design not only ensures the robustness of the connection but also avoids localized damage caused by stress concentration.

[0054] In one specific embodiment, when the luminaire needs to withstand large installation or operational loads, such as large commercial lighting fixtures or outdoor lighting equipment, the strength and reliability of the connection points are crucial. Traditional connection methods often place the connection points in locations with weaker structural strength, making them prone to loosening or damage during long-term use. However, this invention places the mounting part 431 in a high-strength position supported by a double-layer connecting plate, enabling it to withstand greater loads without deformation or damage. Especially under harsh environments such as temperature changes and vibrations, this high-strength connection design maintains long-term stability and reliability.

[0055] By positioning the mounting part 431 at a high-strength location between the first connecting plate 421 and the second connecting plate 422, the advantages of the double-layer support structure are fully utilized, achieving optimal connection performance. The structural strength of the mounting part 431 is significantly higher than other locations, enabling it to withstand greater connection loads without deformation. The connection between the inner frame 1 and the mounting part 431 forms a stable load transfer path, effectively preventing stress concentration and localized damage. Compared to traditional connection methods, this high-strength connection design offers better load-bearing capacity and long-term stability, significantly improving the reliability and durability of the luminaire.

[0056] In some embodiments, the intermediate frame 3 includes a housing 31, and a light groove 311 is provided at one end of the housing 31 facing the first connecting plate 421. The housing 31 is made of a light-transmitting material. The light housing also includes a first light strip 5, which is disposed on the first connecting plate 421 and located in the light groove 311.

[0057] In this embodiment, by setting a light groove 311 on the housing 31 and using a light-transmitting material, combined with the installation of the first light strip 5, the lighting and dimming functions of the housing 31 are realized, creating a soft ambient lighting effect. The first light strip 5 is mainly used to illuminate the housing 31. The light diffuses in all directions through the light-transmitting material of the housing 31, providing auxiliary lighting and decorative effects for the lamp in addition to the main lighting. The design of the light groove 311 ensures good optical coordination between the first light strip 5 and the housing 31, ensuring the uniformity and aesthetics of the lighting effect, and avoiding the uneven lighting and glare problems caused by direct illumination from a point light source.

[0058] Specifically, the first connecting plate 421 abuts against the housing 31 on the side facing the housing 31, providing reliable support for the housing 31 and preventing deformation or detachment during use, thus ensuring the structural stability and safety of the entire lamp housing. It also prevents displacement or deformation of the housing 31 under external force. Simultaneously, the first connecting plate 421 provides a support platform for the installation of subsequent functional components. Furthermore, the abutment between the first connecting plate 421 and the housing 31 prevents the housing 31 from loosening due to thermal expansion and contraction, ensuring long-term stable use of the lamp. The first light strip 5 uses an LED light strip. A light groove 311 is provided at the end of the housing 31 facing the first connecting plate 421. This light groove 311 is specifically designed to accommodate the first light strip 5, ensuring a precise fit between the light strip and the housing 31. The housing 31 is made of a light-transmitting material, such as transparent or semi-transparent plastic or glass, allowing the light emitted by the first light strip 5 to pass through effectively. The first light strip 5 is mounted on the first connecting plate 421 and located within the light groove 311. This design allows the light emitted by the light strip to evenly illuminate the housing 31, and then diffuse outwards through the light-transmitting properties of the housing 31, forming a soft, ring-shaped lighting effect. This lighting method differs from traditional direct lighting and can create a warm and comfortable atmosphere.

[0059] In one specific embodiment, this technical solution is particularly suitable for places requiring a special lighting atmosphere, such as hotel lobbies, high-end residences, and conference rooms. The light emitted by the first light strip 5 through the housing 31 can create soft ambient light in the space, forming a richly layered lighting effect with the main LED lights inside the luminaire. Users can adjust the intensity of the ambient lighting by controlling the brightness of the first light strip 5 to meet their personalized lighting needs. In addition, this design can also provide weak guide lighting at night, meeting basic lighting needs without generating excessive light interference.

[0060] By incorporating a light trough 311 and a first light strip 5 within the housing 31, the light-transmitting characteristics of the housing 31 are fully utilized, achieving an organic integration of structural and lighting functions. The first light strip 5 not only provides illumination to the housing 31 but also diffuses light in all directions through the housing 31, creating a unique ambient lighting effect. This design significantly enriches the lighting functions of the luminaire, enabling a single luminaire to simultaneously provide main lighting, ambient lighting, and decorative lighting effects. Compared to traditional single-lighting designs, this multi-layered lighting scheme offers better lighting quality and richer functional performance.

[0061] like Figure 8 As shown, in some embodiments, the first connecting plate 421 is provided with a groove 4211 on the side facing the housing 31, and the first light strip 5 is disposed in the groove 4211.

[0062] In this embodiment, the first light strip 5 is installed by providing a groove 4211 on the side of the first connecting plate 421 facing the housing 31. This provides more space, facilitating precise positioning and secure fixing of the first light strip 5. Simultaneously, the recessed installation design of the groove 4211 effectively prevents accidental damage to the first light strip 5 during assembly. The groove 4211 design allows the first light strip 5 to be embedded within it, preventing the light strip from being directly exposed. This not only improves the neatness and integrity of the lamp's appearance but also provides physical protection for the light strip, ensuring reliable installation and safe use.

[0063] Specifically, the first connecting plate 421 has a dedicated groove 4211 on the side facing the housing 31. The depth, width, and shape of this groove 4211 are designed according to the size and installation requirements of the first light strip 5. The groove 4211 provides dedicated space for the first light strip 5, allowing the light strip to be fully or partially embedded within it, creating a recessed installation effect. This design not only provides precise positioning for the light strip but also provides lateral support and protection for the light strip through the edge structure of the groove 4211. After the first light strip 5 is installed in the groove 4211, its surface is basically flush with or slightly lower than the surface of the first connecting plate 421, resulting in a neat appearance.

[0064] In one specific embodiment, this groove 4211 mounting design exhibits significant advantages on automated production lines. The groove 4211 provides a clear positioning reference, making the automated installation of the first light strip 5 more precise and reliable. During assembly, the light strip is guided into the groove 4211, avoiding installation deviations or damage caused by inaccurate positioning. The protective function of the groove 4211 also prevents subsequent assembly processes from causing accidental impacts or damage to the installed light strip. Furthermore, the groove 4211 design facilitates heat dissipation for the light strip; a heat dissipation structure or thermally conductive material can be installed at the bottom of the groove 4211, improving the operational reliability and service life of the light strip.

[0065] The use of a dedicated groove 4211 in the first connecting plate 421 effectively addresses the shortcomings of planar installation. The groove 4211 provides dedicated space and a positioning reference for the first light strip 5, ensuring installation accuracy and reliability. The protective function of the groove 4211 prevents damage to the light strip during assembly, improving production efficiency and product quality. The recessed installation creates a unified appearance between the light strip and the first connecting plate 421, enhancing the product's aesthetics and perceived quality. Compared to planar installation, the groove 4211 installation offers better positioning accuracy, protection, and appearance.

[0066] like Figure 5 As shown, in some embodiments, the intermediate frame 3 includes a light-transmitting strip 32, and an installation space 6 is formed between the bonding plate 43 and the first frame 41. The lamp housing also includes a second lamp strip 7, which is disposed on the second connecting plate 422 and located within the installation space 6. The light-transmitting strip 32 is installed within the installation space 6 and is made of an elastic material to enclose the installation space 6.

[0067] In this embodiment, by setting the second light strip 7 to illuminate downwards, forming an integrated structure with the bottom light-transmitting plate of the lamp, a frameless overall lighting effect is achieved, creating a three-dimensional all-around lighting environment. The second light strip 7 is located on the side of the second connecting plate 422 away from the housing 31, providing downward lighting function. In conjunction with the downward light emission from the bottom light-transmitting plate, a continuous downward lighting surface is formed. The light-transmitting strip 32 is installed in the installation space 6 formed between the bonding plate 43 and the first frame 41. It is used to enclose the space while being translucent, allowing the light-transmitting strip 32 to emit light downwards at the lamp housing position. Together with the light emission from the housing 31 in all directions, it forms a unified lighting system, achieving a three-dimensional lighting effect of downward illumination from the bottom, diffused light from all directions, and translucent light along the outline.

[0068] Specifically, the second light strip 7 uses an LED light strip and is installed on the side of the second connecting plate 422 away from the housing 31. This position allows the second light strip 7 to provide downward illumination, coordinating with the main lighting at the bottom of the luminaire. The light-transmitting strip 32, as a sealing and decorative component, is installed within the installation space 6. It not only encloses the installation space 6 but also transmits light, allowing light from the second light strip 7 or ambient light to pass through. When the second light strip 7 is working, some light is transmitted downward through the light-transmitting strip 32, creating a luminous effect at the outline of the luminaire, forming a unified overall lighting surface with the main lighting at the bottom and the surrounding lighting of the housing 31. This design eliminates the obvious boundaries between the various light-emitting parts in traditional luminaires, creating a borderless visual effect.

[0069] In one specific embodiment, this three-dimensional lighting design is particularly suitable for modern minimalist interior lighting, such as modern office spaces, high-end commercial venues, and art galleries. The frameless overall lighting effect creates a simple and modern visual experience, avoiding the visual segmentation caused by traditional lamp frames. The downward illumination of the second light strip 7 forms a continuous lighting surface with the bottom light-transmitting plate, providing uniform work lighting; the contour luminous effect of the light-transmitting strip 32 increases the decorative appeal of the lamp; and the perimeter luminous effect of the housing 31 provides soft ambient lighting. The organic combination of these three lighting effects creates a richly layered and visually continuous lighting environment.

[0070] By incorporating a second light strip 7 and the light-transmitting function of the light-transmitting strip 32, a multi-layered, multi-directional three-dimensional lighting effect is achieved. The downward illumination of the second light strip 7 and the bottom light-transmitting plate form a continuous lighting surface, while the outline light-transmitting effect of the light-transmitting strip 32 enhances the decorative aspect of the lighting. The surrounding illumination of the housing 31 provides ambient light effects. The organic combination of these three lighting methods eliminates the visual boundaries between the various light-emitting parts, creating a frameless overall lighting effect. Compared to traditional separate lighting designs, this three-dimensional lighting scheme offers better visual continuity and richer lighting layers.

[0071] like Figure 8 and 10 As shown, in some embodiments, the first frame 41 and the bonding plate 43 are respectively provided with slots on opposite sides, and the light-transmitting strip 32 has a snap-fit ​​part 321 that snaps into the slot.

[0072] In this embodiment, the snap-fit ​​structure of the slot and snap-fit ​​part 321 enables rapid installation and secure fixation of the light-transmitting strip 32, while ensuring that the light-transmitting strip 32 can fully perform its triple functions of sealing, decoration, and light transmission, thus guaranteeing the integrity of the lamp's outline. Slots are respectively provided on opposite sides of the first frame 41 and the bonding plate 43. The light-transmitting strip 32 has a snap-fit ​​part 321 that engages with the slot. Through the cooperation of the snap-fit ​​structure, the light-transmitting strip 32 can be accurately positioned and securely fixed within the installation space 6. This snap-fit ​​design not only simplifies the assembly process and reduces manufacturing costs, but also ensures a tight fit between the light-transmitting strip 32 and related components, achieving excellent sealing and decorative effects.

[0073] Specifically, the first frame 41 and the bonding plate 43, serving as the boundary structures of the installation space 6, each have dedicated slots on their opposite sides. The shape and size of these slots precisely match the snap-fit ​​portion 321 of the light-transmitting strip 32. The snap-fit ​​portion 321 of the light-transmitting strip 32 engages with the slots through elastic deformation or precise fitting, forming a stable snap-fit ​​connection. This connection method eliminates the need for additional fasteners, simplifying the assembly process while ensuring the reliability of the connection. After the light-transmitting strip 32 is snap-fitted and fixed, it effectively seals the installation space 6, preventing dust, foreign objects, etc. from entering, while its light-transmitting properties allow light within the installation space 6 to pass through, achieving a decorative lighting effect.

[0074] In one specific embodiment, this snap-fit ​​installation design is particularly suitable for mass-produced lighting products, such as standardized LED ceiling lights and downlights. The snap-fit ​​structure allows for automated or semi-automated assembly of the light-transmitting strip 32, significantly improving production efficiency and reducing labor costs. Simultaneously, the detachable nature of the snap-fit ​​connection facilitates subsequent maintenance and replacement; users can easily disassemble the light-transmitting strip 32 for cleaning or replacement, extending the product's lifespan. Furthermore, the triple-functional design of the light-transmitting strip 32 allows a single component to simultaneously meet the needs of sealing, decoration, and lighting, simplifying the product structure and reducing material costs.

[0075] The light-transmitting strip 32 is installed and securely fixed without damage by a specially designed slot and snap-fit ​​structure 321. The snap-fit ​​structure eliminates the need for additional fixing holes on the light-transmitting strip 32, maintaining its structural integrity and aesthetic appeal. The tight fit of the snap-fit ​​connection also ensures a good seal, effectively preventing the intrusion of foreign objects. The triple-function design of the light-transmitting strip 32 fully leverages the multiple roles of the component, achieving functional integration and cost optimization. Compared to traditional fixing methods, the snap-fit ​​design offers better assembly efficiency, sealing performance, and aesthetic appeal.

[0076] like Figure 10As shown, in some embodiments, the light-transmitting strip 32 is provided with a sealing contact portion 322 that abuts against the outer peripheral surface of the inner frame 1.

[0077] In this embodiment, the sealing contact part 322 abuts against the outer peripheral surface of the inner frame 1, effectively sealing the gap between the bonding plate 43 and the inner frame 1. This prevents moisture, dust, and other foreign objects from entering the lamp fixture through the gap between the bonding plate 43 and the inner frame 1, significantly improving the lamp fixture's protective performance and sealing reliability in this critical area. The cooperation between the inner frame 1 and the sealing contact part 322 forms a specialized sealing structure. This design specifically solves the sealing problem at the joint between the bonding plate 43 and the inner frame 1, ensuring a clean and stable internal environment for the lamp fixture.

[0078] Specifically, in addition to the snap-fit ​​portion 321 that engages with the first frame 41 and the bonding plate 43, the light-transmitting strip 32 also has a sealing abutment portion 322 specifically designed to mate with the inner frame 1. When the light-transmitting strip 32 is installed in place, the sealing abutment portion 322 abuts against the outer circumferential surface of the inner frame 1, forming an effective seal at the junction of the bonding plate 43 and the inner frame 1. This double snap-fit ​​design not only ensures the stable installation of the light-transmitting strip 32 but also provides a dedicated sealing structure at critical sealing locations.

[0079] In one specific embodiment, this specialized sealing design is significant for improving the protection level of the luminaire, especially in applications requiring higher protection levels such as IP54 and IP65. The mating point between the bonding plate 43 and the inner frame 1 is often the most prone to sealing problems in the entire lamp housing structure, as manufacturing tolerances and assembly errors inevitably exist between the two different components. By providing a specialized sealing abutment 322, these errors can be effectively compensated for, ensuring a reliable seal at this location. This design is particularly effective in applications with high protection requirements, such as outdoor lighting, industrial lighting, and bathroom lighting.

[0080] In some embodiments, the inner frame 1 has an annular structure, and the bonding plate 43 has an annular structure and is bonded to the outer peripheral surface of the inner frame 1.

[0081] In this embodiment, by defining the inner frame 1 as a ring structure and the bonding plate 43 as a ring structure, a complete ring-shaped fit between the bonding plate 43 and the outer circumference of the inner frame 1 is achieved, significantly increasing the bonding area and bonding effect. The ring structure design ensures that the bonding plate 43 and the inner frame 1 can achieve a tight fit throughout the entire circumference, eliminating the problems of local gaps and uneven fit. Compared with a segmented bonding structure, the complete ring-shaped bonding plate 43 provides a larger contact area, better load distribution effect, and superior sealing performance, thereby improving the stability of the fit and the reliability of the overall structure.

[0082] Specifically, the annular structure of the inner frame 1 provides a continuous mating surface for the bonding plate 43. The bonding plate 43 also adopts an annular structure, forming a complete 360-degree fit with the outer circumference of the inner frame 1. This annular bonding design eliminates the weak points caused by segmented connections, allowing the load to be evenly distributed across the entire bonding surface and avoiding localized stress concentration. The annular structure also has good resistance to deformation, maintaining shape stability under external forces and ensuring that the bonding effect is not affected. At the same time, the complete annular bonding also forms a continuous sealing surface, effectively preventing the intrusion of foreign objects such as dust and moisture.

[0083] In one specific embodiment, the advantages of the annular bonding structure are more pronounced when the luminaire is used in environments with high sealing requirements, such as bathroom lighting, kitchen lighting, or outdoor lighting. The complete annular bonding plate 43 forms a continuous sealing surface with the inner frame 1. With appropriate sealing materials, a high level of protection can be achieved, effectively preventing moisture, dust, and other foreign objects from entering the luminaire. In addition, the load-distribution effect of the annular structure makes the luminaire more stable when bearing installation or operating loads, and less prone to local deformation or damage.

[0084] In related technologies, the bonding plate 43 may adopt a multi-segment structure arranged circumferentially. Although it can achieve basic bonding functions, the segmented connection has some inherent defects. There are connection gaps between the segments of the segmented bonding plate 43. These gaps not only affect the integrity of the appearance, but may also become stress concentration points, making it prone to loosening or damage during long-term use. In addition, the sealing performance of the segmented structure is relatively poor, making it difficult to meet the requirements of high protection levels.

[0085] The adoption of a complete annular bonding plate 43 design completely solves the problems inherent in segmented structures. The annular bonding plate 43 forms a continuous bonding surface with the inner frame 1, eliminating gaps and weak points in the segmented connections and achieving a truly seamless fit. The complete annular structure provides better load distribution, effectively preventing localized damage caused by stress concentration. The annular bonding also offers excellent sealing performance, meeting the requirements of various harsh environments. Compared to segmented bonding structures, the annular bonding plate 43 design offers better structural integrity, load-bearing capacity, and sealing performance.

[0086] like Figure 11-13 As shown, on the other hand, this embodiment also provides a lamp, including: a top cover 2; the lamp housing described above, wherein the inner frame 1 of the lamp housing is connected to the top cover 2.

[0087] In this embodiment, by combining the lamp housing with the top cover 2, which has an excellent fit structure, to form a complete lighting product, a perfect combination of structure and function is achieved, resulting in a complete lighting solution that is aesthetically pleasing, structurally stable, and functionally complete. The top cover 2, as an important component of the lighting fixture, provides the installation interface, electrical connection functions, and protection for the internal circuitry. Combined with the aforementioned lamp housing, which has a seamless fit structure and multi-layered lighting functions, it forms a technologically advanced and high-performance complete lighting product that meets the comprehensive requirements of modern lighting applications for aesthetics, functionality, and reliability.

[0088] Specifically, the top cover 2, as the top enclosed structure of the lamp, typically includes functional components such as electrical wiring terminals, mounting and fixing structures, and heat dissipation structures, providing the entire lamp with a connection interface to the external power supply and mounting structure. The lamp housing features seamless integration between the outer frame 4 and the inner frame 1, stable support via the extended structure 42, and multi-level lighting functions. When this advanced lamp housing is combined with the top cover 2, a fully functional lamp product is formed. The combination of the top cover 2 and the lamp housing not only achieves structural integrity but also ensures the reliability of electrical connections and the overall aesthetic unity.

[0089] like Figure 13 As shown, specifically, a support member 8 is provided on the inner frame 1. The support member 8 can be a bolt. After the bolt is connected to the inner frame 1, it abuts against the inner surface of the shell 31 to support the shell 31 from the inside. The first connecting plate 421 fits against the outer peripheral surface of the shell 31, thereby realizing the positioning and fixing of the shell 31.
