Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a quick-installation lighting fixture. Background Technology

[0002] Lighting fixtures provide illumination for people's daily lives and are widely used in daily life and other scenarios. Common ceiling lights are fixtures that are directly attached to or fixed to the ceiling. They usually have a simple design and can provide uniform light to a certain space, making them one of the mainstream choices for modern home lighting.

[0003] Existing ceiling lights typically consist of a bracket for fixing to the ceiling and a base assembly that mates with the bracket. The base assembly comprises a stamped metal chassis and a metal edging. The metal edging needs to be welded to the metal chassis, which is not only complex to manufacture but also prone to deformation due to welding, affecting the fit with the bracket and resulting in higher overall costs. Furthermore, the bracket and base assembly require screws for secure fastening, complicating the installation and disassembly process, hindering convenient installation by installers, and reducing time and effort, thus impacting installation efficiency.

[0004] To address the aforementioned problem of inconvenient installation of lighting fixtures, another type of lighting fixture improves installation convenience by fixing the base to the ceiling and then screwing the lamp body to the base. Although this improves installation efficiency, the compact arrangement between the base and the lamp body limits the cooperation with other components and makes it difficult to expand the other performance features of the lighting fixture. Utility Model Content

[0005] This utility model provides a quick-installation lighting fixture to solve the defects of existing lighting fixtures, such as complex structure and manufacturing process, inconvenient installation, and poor performance. It reduces the installation difficulty and improves the ease of installation while expanding the performance of the lighting fixture at a low cost.

[0006] This utility model provides a quick-installation lighting fixture, comprising:

[0007] Mounting bracket, the top of which is used to fix it to the wall, and the outer peripheral wall of the mounting bracket is provided with buckles;

[0008] The quick-install chassis includes a metal chassis body and an annular injection-molded rim protruding upward from the chassis body. The rim is fixed to the chassis body by a connector. The top of the rim is provided with a mating part that engages with a snap fastener. The mounting bracket and the quick-install chassis are detachably installed by the snap fastener and the mating part. The rim and the chassis body enclose a receiving cavity.

[0009] The power supply is located within the receiving cavity;

[0010] The lamp body is located below the quick-release chassis, and a light source structure electrically connected to the power supply is installed inside it.

[0011] Optionally, the mating part is a boss extending inward from the top of the surrounding edge. There are multiple bosses, and an entrance is formed between two adjacent bosses. There are multiple buckles, which correspond one-to-one with the multiple bosses. The buckle enters the surrounding edge through the entrance. When the buckle reaches below the corresponding boss, the boss and the buckle stop and limit the movement.

[0012] Optionally, the buckle includes a horizontal portion extending circumferentially along the annular mounting bracket and a stop portion that bends upward at one end of the horizontal portion, with one end of the boss abutting and limiting the stop portion.

[0013] Optionally, the upper surface of the horizontal portion is provided with at least one horizontally extending rib for abutting against the lower surface of the boss.

[0014] Optionally, the inner sidewall of the top of the mounting bracket is provided with an inwardly extending mounting portion, and the mounting portion is provided with mounting holes for screwing and fixing to the wall.

[0015] Optionally, the mounting bracket is a one-piece injection molded part.

[0016] Optionally, the connector is a screw, and the perimeter is fixed to the disc body by the screw; the edge of the disc body is fixed to the lamp body by screw and surrounds the light source structure, and the light source structure is fixed to the lower surface of the disc body.

[0017] Optionally, the disk body is provided with a wire passage hole so that the wires of the light source structure can be electrically connected to the power supply through the wire passage hole.

[0018] Optionally, the lamp body includes: a frame having an annular cavity and a mask disposed at the bottom of the annular cavity, wherein the top end of the annular cavity is folded inward to form a first annular edge, and the bottom end of the annular cavity is folded inward to form a second annular edge;

[0019] A pressure plate is clamped between the first and second ring edges to confine the mask between the bottom end face of the pressure plate and the second ring edge.

[0020] Optionally, the frame further includes an outer frame connected to the outside of the annular cavity, the outer frame having a closed interlayer, and a light strip being provided inside the closed interlayer.

[0021] The quick-installation lamp provided by this utility model is designed with a quick-installation chassis, which adopts a combination structure of metal chassis and injection-molded edging. The two do not require welding and are fixed by screws. It can be assembled automatically in the workshop. The process is simple and the cost is low. Compared with the conventional structure and method of welding metal chassis and metal edging, it can simplify the process steps, save materials and labor costs, and avoid the problem of deformation caused by welding affecting assembly, thereby ensuring the assembly effect.

[0022] Based on this, the mounting bracket and quick-installation chassis of this utility model are installed by a snap-fit ​​and interlocking mechanism, eliminating the need for screws, effectively reducing installation difficulty, achieving convenient installation, improving installation efficiency, and providing convenience for installers. Furthermore, the quick-installation chassis has a cavity for accommodating the power supply, providing installation space for the power supply. This not only expands the functionality of the quick-installation chassis but also helps reduce the internal space of the lamp body, thereby reducing the lamp's overall size. This avoids placing the power supply and light source structure in the same space, preventing the power supply's shadow from being visible from the outside when the light source is emitting light, which would affect the lighting effect and appearance, thus ensuring the reliability of the lamp.

Obviously, the described embodiments are only some embodiments of this embodiment, not all embodiments. Based on the embodiments of this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this embodiment.

Therefore, they should not be construed as limitations on this embodiment.

[0032] In this embodiment, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment according to the specific circumstances.

[0033] In this embodiment, unless otherwise expressly specified and limited, the first feature "on" or "under" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this embodiment. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] The following is combined with Figures 1 to 4 The quick-installation lighting fixture described in this embodiment includes:

[0035] Mounting bracket 10, the top of which is used to fix it to the wall, and the outer peripheral wall of the mounting bracket 10 is provided with a swivel buckle 11;

[0036] The quick-installation chassis 12 includes a metal chassis 13 and an annular injection-molded rim 14 protruding upward from the chassis 13. The rim 14 is fixed to the chassis 13 by a connector. The top of the rim 14 is provided with a mating part that engages with the swivel buckle 11. The mounting bracket 10 and the quick-installation chassis 12 are detachably installed via the swivel buckle 11 and the mating part.

[0037] Specifically, the edging 14 is made of injection molded material, enabling one-time molding of complex structures. The process is simple, and the material has low density, significantly reducing weight compared to metal parts, making installation easier for installers. By using optimized plastic material, it achieves strength similar to metal, possessing impact resistance and other properties, reducing deformation rate and increasing service life. During injection molding, the material is uniformly filled into the mold, and cooling shrinkage is controllable, enabling high-precision machining and improving the versatility and flexibility of the edging 14's form. Furthermore, the injection-molded edging 14 can integrate a self-positioning structure, facilitating rapid assembly, reducing tooling requirements, and simplifying the assembly process and improving the assembly effect between it and the disc body 13 through a certain range of elastic deformation or interference fit compared to metal parts.

[0038] For example, such as Figure 2As shown, the rim 14 includes an annular main body 141 and a flanged portion 142 that folds outward from the bottom end of the main body 141. The top of the main body 141 has multiple spaced-apart mating parts, and the flanged portion 142 has multiple spaced-apart screw posts 22. The disc body 13 has multiple screw holes corresponding to the screw posts 22. The connecting component is a screw 23, which locks the rim 14 onto the disc body 13, making the operation simple and the fixation secure. The diameter of the disc body 13 is larger than the outer diameter of the flanged portion 142, giving the disc body 13 more space, for example, facilitating the placement of more light source structures 17.

[0039] Preferably, the mounting bracket 10 is also made of injection molded parts, which is easier to mold and has a lower cost compared to existing metal brackets. Moreover, when the mounting bracket 10 and the surrounding edge 14 are assembled, both being injection molded parts allows the relevant components to improve the assembly effect through elastic deformation or interference fit, which can avoid the scratches that can easily occur when one part is made of metal and the other of plastic, thus affecting the service life of the structure.

[0040] During installation, first fix the mounting bracket 10 to the ceiling. Then, align the quick-release base 12 and the lamp body assembly upwards with the mounting bracket 10, allowing the mounting bracket 10 to fit into the edging 14. Rotate the quick-release base 12 until the buckle 11 engages with the mating part, completing the installation. Compared to existing screw-locking methods, this reduces installation difficulty and eliminates the need for two people; one person can perform the installation quickly.

[0041] Furthermore, the perimeter 14 and the disc body 13 enclose a receiving cavity 15. The quick-installation lamp also includes: a power supply 16, which is disposed in the receiving cavity 15; and a lamp body, which is disposed below the quick-installation chassis 12, and has a light source structure 17 that is electrically connected to the power supply 16.

[0042] like Figure 1 and Figure 2 As shown, the main body 141 of the edging 14 has a certain height, which can accommodate the power supply 16, making effective use of the space of the edging 14. The mounting bracket 10, power supply 16, and quick-release chassis 12 are compactly arranged, improving space utilization and facilitating the miniaturization of the lamp. It is understood that the lamp body also has an inner cavity, with the light source structure 17 located within it. This separates the light source structure 17 from the power supply 16. Since the power supply 16 has a certain thickness, placing it within the aforementioned accommodating cavity 15 helps reduce the space within the lamp body's inner cavity. This allows the light emitted by the light source structure 17 to be transmitted over short distances, ensuring light intensity. Simultaneously, it avoids placing the power supply 16 and the light source structure 17 in the same space, preventing the shadow of the power supply 16 from being visible from the outside when the light source structure 17 is emitting light, which would affect the lighting effect and appearance, thus ensuring the reliability of the lamp.

[0043] Based on the quick-release structure formed by the mounting bracket 10 and the quick-release chassis 12, the installation and maintenance of the power supply 16 are also facilitated. When the power supply 16 fails or runs out of power, it can be easily removed and replaced by disassembling the quick-release chassis 12 without disassembling the lamp body, reducing the amount of user work and improving the user experience. Moreover, the power supply 16 can dissipate heat through the open position at the top of the housing cavity 15, which optimizes the heat dissipation effect of the power supply 16 and improves its lifespan and performance.

[0044] In a preferred embodiment, the mating part is a boss 18 extending inward from the top of the perimeter 14. There are multiple bosses 18, and an entrance 181 is formed between two adjacent bosses 18. There are multiple buckles 11, which correspond one-to-one with the multiple bosses 18. The buckle 11 enters the perimeter 14 through the entrance 181. When the buckle 11 reaches below the corresponding boss 18, the boss 18 and the buckle 11 stop and limit the movement.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, when installing the lamp, first align the inlet 181 with the buckle 11, then fit the mounting bracket 10 into the surrounding edge 14, and then rotate the quick-installation base 12 to change the position of the buckle 11 relative to the inlet 181 until the buckle 11 reaches below the corresponding protrusion 18. The protrusion 18 is hooked onto the buckle 11, and the two achieve a stop and limit, completing the installation of the lamp. The structure and number of protrusions 18 can be set according to actual needs, and this embodiment does not limit them. Figure 2 Four protrusions 18 are provided, evenly distributed around the perimeter 14, and correspondingly, four buckles 11 are also provided.

[0046] Furthermore, the swivel buckle 11 includes a horizontal portion 111 extending circumferentially along the annular mounting bracket 10 and a stop portion 112 that bends upward at one end of the horizontal portion 111, with one end of the boss 18 abutting and limiting the stop portion 112.

[0047] like Figure 3 As shown, the swivel 11 is L-shaped, with the end of the horizontal part 111 away from the stop part 112 being the front end. When the quick-installation chassis 12 rotates, the boss 18 moves from the front end of the horizontal part 111 to the rear end until the boss 18 abuts against the stop part 112 to achieve the limit. It can also provide a tactile feedback to indicate that the installation is in place, thereby ensuring reliable installation.

[0048] Furthermore, the upper surface of the horizontal portion 111 is provided with at least one horizontally extending rib 113 for abutting against the lower surface of the boss 18.

[0049] The raised rib 113 can increase the friction between the boss 18 and the horizontal part 111, prevent the quick-release chassis 12 from sliding accidentally and affecting the hooking effect of the boss 18, and ensure the assembly firmness and reliability.

[0050] It is understood that in other embodiments, the rib 113 may also be provided on the lower surface of the boss 18, which can also increase the friction between the boss 18 and the horizontal part 111.

[0051] In addition to the methods described above, in another embodiment, the mating part is a groove protruding from the inner wall of the perimeter 14. Along the rotation direction of the quick-assembly chassis 12, the front end of the groove has an opening for inserting the screw fastener 11, and the rear end has a retaining rib to prevent the screw fastener 11 from disengaging. In this embodiment, the mating part uses a groove to clamp the screw fastener 11, improving structural processing flexibility and enriching assembly methods.

[0052] In a preferred embodiment, the inner sidewall of the top of the mounting bracket 10 is provided with an inwardly extending mounting portion 101, and the mounting portion 101 is provided with mounting holes 102 for screwing and fixing to the wall.

[0053] like Figure 3 As shown, the mounting part 101 is similar to a lug structure. The mounting part 101 and the screw fastener 11 are respectively located on the inner and outer circumferences of the mounting bracket 10, which can improve space utilization and avoid assembly interference. When installing the light fixture, it is first fixed to the ceiling screws through the mounting part 101, and then the quick-installation base 12 is installed from bottom to top.

[0054] Preferably, the mounting bracket 10 is a one-piece injection molded part. This allows for one-time molding of complex structures, simplifies the process, and utilizes a low-density material, significantly reducing weight compared to metal parts, making installation easier for installers. By using optimized plastic materials, it achieves strength similar to metal, possesses impact resistance, reduces deformation rate, and increases service life. During injection molding, the material is uniformly filled into the mold, and cooling shrinkage is controllable, enabling high-precision processing and increasing the versatility and flexibility of the mounting bracket 10's form. Conventional metal brackets, often in the form of a cross bracket, consist of two long, rectangular frames welded together. Screw holes are pre-drilled at the ends of the cross bracket. When installing light fixtures, the bracket needs to be screwed into the chassis assembly through these holes, making installation difficult. This requires aligning multiple screw holes and individually driving screws, potentially requiring two people to work together, resulting in time-consuming, labor-intensive, and costly installation. The mounting bracket 10 in this embodiment is optimized in both processing and use, saving processing and installation labor costs, and enabling rapid installation of a low-cost structure.

[0055] In a preferred embodiment, the edge of the disc body 13 is fixed to the lamp body screw 23 and surrounds the light source structure 17, which is fixed to the lower surface of the disc body 13.

[0056] In this embodiment, the disk body 13 provides a mounting surface for the light source structure 17, further expanding the functionality of the quick-mount chassis 12 and enabling a compact arrangement of the structures. The light source structure 17 can be fixed by means such as screws, snap-fit, or adhesive, and this embodiment does not limit the method.

[0057] In some embodiments, the light source structure 17 includes an aluminum substrate 171 and LED beads disposed on the aluminum substrate 171, such as... Figure 1 As shown, multiple aluminum substrates 171 can be fixed to the lower surface of the disk body 13 by screws.

[0058] Furthermore, the disk body 13 is provided with a wire passage hole 131, so that the wire of the light source structure 17 can be electrically connected to the power supply 16 through the wire passage hole 131. When the wire passage hole 131 is located in the area surrounded by the perimeter 14, the wire can be directly connected to the power supply 16 by passing through the wire passage hole 131. When the wire passage hole 131 is located outside the area surrounded by the perimeter 14, notches or through holes can be further provided on the side wall of the perimeter 14 to facilitate the wire passing through the notches or through holes to connect to the power supply 16 in the receiving cavity 15.

[0059] Furthermore, the lamp body includes: a frame 19 having an annular cavity 191 and a mask 20 disposed at the bottom of the annular cavity 191, the top end of the annular cavity 191 being folded inward to form a first annular edge 192, and the bottom end of the annular cavity 191 being folded inward to form a second annular edge 193;

[0060] A pressure plate 21 is clamped between the first ring edge 192 and the second ring edge 193 to confine the mask 20 between the bottom end face of the pressure plate 21 and the second ring edge 193.

[0061] like Figure 1 As shown, the annular cavity 191 and the disk 13 enclose the light source structure 17, ensuring a focused light effect and providing dust and water resistance. The light emitted by the light source structure 17 can be projected onto the outside through the face mask 20, providing illumination. This embodiment provides a method for fixing the face mask 20 by pressing it with pressure plates 21, which simplifies installation and improves installation efficiency. Multiple pressure plates 21 are spaced apart along the circumference of the annular cavity 191, such as... Figure 4As shown, the pressure plate 21 includes a vertically extending plate body 211 and a surrounding rib protruding outward from the circumferential edge of the plate body 211. The upper surrounding rib 212 abuts against the first ring edge 192, and the lower surrounding rib 213 abuts against the second ring edge 193. Furthermore, the bottom of the lower surrounding rib 213 is also provided with a downwardly extending limiting rib 214, which can realize the radial limitation of the mask 20, prevent the mask 20 from shifting, and improve its installation reliability.

[0062] In order to optimize the installation effect of the pressure plate 21, in some embodiments, the two ends of the upper rib 212 of each pressure plate 21 are respectively provided with studs 215 and positioning posts 216. The first ring edge 192 is provided with screw holes 195 corresponding to the studs 215 and positioning holes 196 corresponding to the positioning posts 216. By positioning the pressure plate 21 and screwing in the screws, the installation firmness of the pressure plate 21 can be improved, thereby improving the installation effect of the face mask 20.

[0063] In some embodiments, the disc body 13 and the frame 19 are fixed with screws, for example, the edge of the disc body 13 is fixed with screws to the first ring edge 192. To simplify the installation process, the screws 23 passing through the disc body 13 can pass through the studs 215 on the pressure plate 21 and then be fastened to the first ring edge 192. This allows the disc body 13, the pressure plate 21, and the frame 19 to be fixed with the same fastener, which reduces the use of accessories, saves installation steps, and improves installation efficiency.

[0064] Furthermore, the frame 19 also includes an outer frame 194 connected to the outside of the annular cavity 191, the outer frame 194 having a closed interlayer, and a light strip is provided in the closed interlayer.

[0065] like Figure 1 As shown, the frame 19 has an inner frame and an outer frame 194. The inner frame surrounds and forms an annular cavity 191, providing a space for the light source structure 17. The outer frame 194 serves both a decorative purpose and houses a light strip to enhance the lighting effect of the lamp. In some embodiments, the light source structure 17 and the light strip can be controlled independently. The light source structure 17 can provide a stronger lighting effect, while the soft light emitted by the annular light strip can enhance the atmosphere and improve the user experience. The light strip can emit light continuously or have a flashing dynamic effect, which can be set according to actual needs, so that the lamp can not only serve as illumination but also as an ambient light, improving its performance.

[0066] The quick-installation lighting fixtures provided in the above embodiments and examples are designed with a quick-installation chassis 12, which adopts a combination structure of a metal disc body 13 and an injection-molded edging 14. The two do not require welding and are fixed by screws. They can be assembled automatically in the workshop, with simple process and low cost. Compared with the conventional structure and method of welding the metal chassis to the metal edging 14, it can simplify the process steps, save materials and labor costs, and avoid the problem of deformation caused by welding affecting the assembly, thereby ensuring the assembly effect.

[0067] Based on this, the mounting bracket 10 and the quick-installation chassis 12 are installed by a snap-fit ​​connection using a screw 11 and a mating part, eliminating the need for screws 23, effectively reducing installation difficulty, achieving convenient installation, improving installation efficiency, and providing convenience for installers. Furthermore, the quick-installation chassis 12 has a receiving cavity 15 that can accommodate the power supply 16, providing installation for the power supply 16. This not only expands the functionality of the quick-installation chassis 12 but also helps reduce the internal space of the lamp body, thereby reducing the lamp body size. This avoids placing the power supply 16 and the light source structure 17 in the same space, preventing the shadow of the power supply 16 from being visible from the outside when the light source structure 17 is emitting light, which would affect the lighting effect and appearance, thus ensuring the reliability of the lamp.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this embodiment, and not to limit them; although this embodiment has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this embodiment.
