Description

Technical Field

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

[0002] Surface-mounted lights are widely used in indoor lighting scenarios such as homes, offices, and commercial spaces due to their advantages of convenient installation and wide applicability. Most existing surface-mounted lights use a structure where a mounting plate and a rectangular lamp housing are assembled together. To simplify the assembly process and achieve quick, screwless assembly and disassembly, most industry manufacturers use a snap-fit ​​connection structure with elastic positioning components and positioning slots to securely assemble the mounting plate and the rectangular lamp housing.

[0003] However, the current mainstream connection structure has obvious structural defects and production drawbacks. In existing technologies, the positioning grooves used to cooperate with the elastic positioning components are all directly opened on the side wall of the rectangular lamp housing. Since the rectangular lamp housing is a one-piece shell structure, and the positioning groove on the side wall is an inwardly recessed irregular groove structure, conventional upper and lower opening molds cannot directly complete the demolding operation during the injection molding process of the lamp housing. It is necessary to add a corresponding internal sliding demolding mechanism inside the mold to achieve complete demolding of the lamp housing with positioning grooves.

[0004] This mold structure design significantly increases the overall complexity of the mold, not only raising the design, processing, and debugging costs and extending the mold development cycle, but also making the internal slider mechanism prone to jamming, wear, and displacement during long-term, high-frequency injection molding production. This reduces the mold's lifespan and production stability, increasing the mass production cost and defect rate of the lamps. Furthermore, the slotted processing method on the lamp housing sidewalls weakens the structural strength of the sidewalls, making them susceptible to deformation and loosening of clips during long-term use. This leads to loosening of the connection between the mounting plate and the lamp housing, affecting the overall installation stability and safety of the lamp, making it difficult to meet the demands of high-quality, low-cost mass production and long-term use. Utility Model Content

[0005] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a surface-mounted light with optimized structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A surface-mounted light includes a mounting plate and a rectangular lamp housing. The rectangular lamp housing has open ends. The mounting plate is located at the upper opening of the rectangular lamp housing. A driving power supply and a lighting component are disposed inside the rectangular lamp housing. The lighting component is located at the lower opening of the rectangular lamp housing. A metal protective cover plate is also disposed inside the rectangular lamp housing and covers the driving power supply. An upwardly extending support plate is integrally bent on both sides of the metal protective cover plate. A positioning groove is formed on the support plate. Elastic positioning components that cooperate with the positioning groove are disposed on both sides of the mounting plate.

[0008] In some embodiments, the elastic positioning component includes fixed seats disposed on the left and right sides of the mounting plate, and stepped countersunk holes are provided at intervals on the outer sides of the two fixed seats. A stepped positioning bead is provided in each stepped countersunk hole, and the steel ball of the stepped positioning bead cooperates with the positioning groove.

[0009] In some embodiments, the positioning groove is a strip-shaped structure extending in the front-back direction.

[0010] In some embodiments, the upper end of the support plate abuts against the extended flanges extending outward on both the left and right sides of the upper end of the mounting plate when the steel ball of the step positioning bead engages with the positioning groove.

[0011] In some embodiments, the mounting plate has a first through hole for the power cord to pass through and a mounting hole for the screw to pass through.

[0012] In some embodiments, a partition is provided inside the rectangular lamp housing, and the partition divides the rectangular lamp housing into an upper space and a lower space. The driving power supply is located in the upper space, and the lighting component is located in the lower space.

[0013] In some embodiments, screw posts are spaced apart on the left and right sides of the front side of the upper space, and slots are spaced apart on the left and right sides of the rear side. The metal protective cover includes a horizontal plate and a vertical plate connected in sequence in an L-shape. The horizontal plate abuts against the screw posts and is fixed by screws cooperating with the screw posts. The vertical plate is inserted into the slots. The support plate is disposed on the horizontal plate. A second wire hole is provided on the vertical plate.

[0014] In some embodiments, the lighting assembly includes a lamp plate, a reflector, a lens, and an anti-glare shield, which are sequentially disposed on the lower side of the partition.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This solution moves the positioning groove from the original rectangular lamp housing sidewall to the support plate of the metal protective cover. The rectangular lamp housing no longer needs a positioning groove, resulting in a regular rectangular through-shell structure. During injection molding, no additional design or internal slider demolding mechanism is required; a conventional top-and-bottom opening mold is sufficient for demolding. This significantly simplifies the mold structure of the lamp housing, reduces mold design, processing, and maintenance costs, shortens the mold development cycle, reduces the probability of mold failure, improves the stability and efficiency of injection molding production, and effectively reduces the overall cost of mass production of lamps.

[0017] 2. This design preserves the overall integrity of the rectangular lamp housing, maximizing its structural strength and minimizing deformation. Simultaneously, the positioning groove is located on a metal support plate. The metal structure boasts significantly higher strength than plastic lamp housings, offering superior wear resistance and deformation resistance. The elastic positioning components and metal positioning grooves exhibit higher precision and stability in their fit, reducing the likelihood of loosening or detachment over long-term use. This effectively enhances the overall installation stability and durability of the lamp fixture.

[0018] 3. The metal protective cover in this structure not only protects and isolates the driving power supply by covering it, effectively preventing dust and impacts and protecting the power components from damage, thus improving the electrical safety and service life of the lamp, but also integrates a positioning groove structure through an integrally bent support plate. This multi-functional design with high structural integration eliminates the need for additional positioning accessories, simplifies the internal assembly structure of the lamp, reduces the number of parts, further reduces assembly processes and production costs, and improves the compactness and regularity of the internal structure of the lamp.

[0026] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0027] like Figures 1-7 The surface-mounted light shown includes a mounting plate 1 and a rectangular lamp housing 2. The rectangular lamp housing 2 has open structures at both the top and bottom. The mounting plate 1 is located at the upper opening of the rectangular lamp housing 2. A driving power supply 3 and a lighting component are installed inside the rectangular lamp housing 2. The lighting component is located at the lower opening of the rectangular lamp housing 2. A metal protective cover plate 4 is also installed inside the rectangular lamp housing 2, covering the driving power supply 3. Support plates 5 are integrally bent and extended upward on both the left and right sides of the metal protective cover plate 4. Positioning grooves 6 are provided on the support plates 5. Elastic positioning components that cooperate with the positioning grooves 6 are provided on both the left and right sides of the mounting plate 1.

[0028] According to the above structure, when this surface-mounted light is assembled and used, the mounting plate 1 is pre-fixed on the ceiling or rooftop as a fixed support base for the entire light fixture, providing stable installation support for the entire light fixture. The rectangular lamp housing 2 adopts an open structure with both ends open, resulting in a simple overall assembly structure and ample space for disassembly and assembly. The upper opening of the rectangular lamp housing 2 corresponds to the position of the mounting plate 1, and the lower opening is used to install and fix the lighting components, realizing the basic lighting function of the light fixture. The internal cavity of the rectangular lamp housing 2 is used to accommodate and install the driver power supply 3, which provides stable power to the lighting components, ensuring the normal operation of the light fixture.

[0029] Inside the lamp, a metal protective cover 4 is installed on the outside of the driver power supply 3. The metal protective cover 4 completely covers and protects the driver power supply 3, preventing dust and impact damage, thus improving the electrical safety and lifespan of the lamp. The left and right sides of the metal protective cover 4 are integrally bent and have upwardly extending support plates 5. The integral bending structure ensures the overall structural strength of the support plates 5 and the metal protective cover 4, making it less prone to deformation and breakage.

[0030] During the overall assembly of the lamp fixture, the positioning groove 6 on the support plate 5 and the elastic positioning components on the left and right sides of the mounting plate 1 form a precise snap-fit. During the assembly process, the rectangular lamp housing 2 is aligned with the mounting plate 1 from bottom to top, so that the elastic positioning components are correspondingly snapped into the positioning groove 6 of the support plate 5. Through the elastic clamping characteristics of the elastic positioning components and the limiting cooperation of the positioning groove 6, the mounting plate 1 and the rectangular lamp housing 2 are quickly positioned and locked in place. No screws are required for fastening, and the entire lamp fixture can be assembled quickly without tools.

[0031] Meanwhile, this structure integrates the positioning and limiting structure onto the support plate 5 of the metal protective cover 4, replacing the traditional limiting structure with slots on the side wall of the lamp housing. This eliminates the need to create slots on the side wall of the rectangular lamp housing 2, ensuring the structural integrity of the rectangular lamp housing 2. At the same time, the high strength of the metal support plate 5 enhances the wear resistance and deformation resistance of the positioning slot 6, ensuring the stability of the long-term connection between the mounting plate 1 and the rectangular lamp housing 2. This effectively avoids problems such as loosening or falling off during the use of the lamp, balancing ease of assembly and reliability of use.

[0032] In this invention, the elastic positioning component mainly consists of a fixed base 21, a stepped countersunk hole 22, and a stepped positioning bead 23. The fixed base 21 is correspondingly arranged on the left and right sides of the mounting plate 1, serving as the bearing base of the positioning structure and providing a stable installation foundation for the subsequent elastic locking structure. Each fixed base 21 has stepped countersunk holes 22 spaced apart on its outer side. The stepped positioning beads 23 are correspondingly assembled inside each stepped countersunk hole 22. The stepped structure of the stepped countersunk hole 22 is used to limit and fix the stepped positioning beads 23, preventing them from falling off or shifting, and ensuring the stability of their installation position. When assembling and aligning the lamps, the steel ball portion of the stepped positioning bead 23 forms an elastic locking fit with the positioning groove 6 on the support plate 5. Utilizing the elastic expansion and contraction characteristics of the steel ball, a smooth alignment and firm locking assembly effect is achieved.

[0033] The positioning groove 6 is designed as a strip-shaped structure extending in the front-to-back direction, which can be precisely matched with multiple sets of stepped positioning beads 23 distributed at intervals in the front and back, effectively increasing the contact range. At the same time, it can accommodate small alignment deviations during assembly and avoid the problem of easy loosening or displacement of single-point positioning.

[0034] Extending flanges 41 are provided on the left and right sides of the upper end of the mounting plate 1. When the steel ball of the step positioning bead 23 is engaged with the positioning groove 6, the upper end face of the support plate 5 is tightly pressed against the extending flanges 41. The extending flanges 41 form a vertical limiting support for the support plate 5, restricting the vertical displacement of the support plate 5 and the overall rectangular lamp housing 2.

[0035] The mounting plate 1 is provided with a first wire-passing hole 51 and a mounting hole 52. The mounting hole 52 allows external fastening screws to pass through, making it easy to firmly fix the mounting plate 1 to the ceiling, roof or other mounting base, so as to achieve a stable installation and positioning of the mounting plate 1. The first wire-passing hole 51 allows the power cord of the lamp to pass through and be arranged, so as to organize the power cord routing path and avoid the power cord being squeezed, bent or messy and exposed. This ensures the neatness and safety of the lamp wiring installation, and also adapts to the conventional wiring installation needs of surface-mounted lights, thus improving the product's installation compatibility.

[0036] See Figure 3 , Figure 4 , Figure 6 As shown, by adding a partition 61 inside the rectangular lamp housing 2, the internal cavity of the rectangular lamp housing 2 is independently divided into an upper space 62 and a lower space 63, thereby achieving a partitioned arrangement of the electrical structure and the light-emitting structure of the lamp. The driving power supply 3 is centrally installed inside the upper space 62, and the lighting components are arranged as a whole inside the lower space 63, effectively achieving physical isolation between the power driving area and the light-emitting lighting area.

[0037] The upper space 62 of the rectangular lamp housing 2 has screw posts 71 spaced apart on the left and right sides at the front, and slots 72 spaced apart on the left and right sides at the rear, for fixing the metal protective cover 4. The metal protective cover 4 is an L-shaped integral structure formed by connecting horizontal plates 73 and vertical plates 74 in sequence. During assembly, the horizontal plate 73 at the front of the metal protective cover 4 fits against the upper surface of the screw posts 71, and is locked in place by screws 75 and screw posts 71. The vertical plate 74 at the rear of the metal protective cover 4 is inserted into the slots 72 at the rear of the upper space 62, forming an insertion limiting structure. Through the combination of front screw locking and rear insertion limiting, the metal protective cover 4 can be installed quickly and accurately, is easy to assemble, and is firmly fixed, effectively preventing the metal protective cover 4 from shifting or loosening.

[0038] The support plate 5, which mates with the elastic positioning component of the mounting plate 1, is integrally mounted on the horizontal plate 73. This allows the support plate 5 to be positioned and fixed synchronously with the metal protective cover plate 4, ensuring the installation accuracy and structural stability of the support plate 5. This provides reliable structural support for the subsequent precise snap-fit ​​assembly of the mounting plate 1 and the rectangular lamp housing 2. Simultaneously, the vertical plate 74 has a second wiring hole 76, allowing the connection harness of the drive power supply 3 to pass through. This enables the wiring connection between the drive power supply 3 in the upper space 62 and the lighting components in the lower space 63, standardizing the wiring route, preventing wire compression, bending, and tangling, and improving the neatness of the lamp wiring and electrical safety.

[0039] The lighting components adopt a layered stacked structure, assembled sequentially from top to bottom on the underside of the partition 61. Specifically, they include a lamp panel 81, a reflector 82, a lens 83, and an anti-glare cover 84. The lamp panel 81 serves as the light source, providing basic illumination. The reflector 82 can converge and reflect the light emitted from the lamp panel 81, reducing light loss and improving the light output efficiency and uniformity of the luminaire. The lens 83 performs secondary optical adjustment of the light, optimizing the light output effect and ensuring soft and uniform illumination. The outermost anti-glare cover 84 can effectively block direct strong light, avoiding glare and significantly improving the lighting comfort and user experience of the luminaire. At the same time, the multi-layered structure is compactly assembled, effectively improving the overall structural strength and assembly stability of the lighting components.
