[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The technical solutions disclosed in the various embodiments of this application will be described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0026] Please refer to Figures 1 to 6 This application discloses a lighting fixture, which includes a substrate 100, a mounting part 200, and a light source module 300.

[0027] The substrate 100 serves as the basic component of the lighting fixture, providing a mounting base for other parts of the fixture. A printed circuit 120 is provided on the first surface 130 of the substrate 100, eliminating the need for a separate circuit board assembly within the lighting fixture. In this configuration, the substrate 100 can function as part of the lighting fixture's housing and power module, achieving a multi-functionality and reducing the number of components, thus simplifying the fixture's structure. The specific process for providing the printed circuit 120 on the substrate 100 is known technology and will not be described further for the sake of brevity.

[0028] The substrate 100 and the mounting portion 200 are disposed opposite to each other, so that the substrate 100 and the mounting portion 200 form the housing of the lighting fixture. Since the substrate 100 and the mounting portion 200 can be plate-shaped, and the substrate 100 and the mounting portion 200 are disposed opposite to each other, or the substrate 100 can be attached to the mounting portion 200, the thickness of the housing formed by the substrate 100 and the mounting portion 200 is small. This allows the lighting fixture to be made thinner and has a neat and clean appearance, thus simplifying the appearance of the lighting fixture. The substrate 100 and the mounting portion 200 can be of various types, such as rigid plastic sheets, acrylic sheets, and metal sheets, etc., and this embodiment does not limit them.

[0029] Specifically, the first surface 130 of the substrate 100 faces the mounting portion 200. That is, the surface of the substrate 100 that is opposite to the mounting portion 200 is the first surface 130, so that the printed circuit 120 is located inside the lighting fixture, preventing the printed circuit 120 from being exposed outside the lighting fixture and affecting the appearance of the lighting fixture. At the same time, the fact that the printed circuit 120 is located inside the lighting fixture can also provide better protection for the printed circuit 120, preventing impurities (dust or liquid) from falling on the printed circuit 120, thereby avoiding poor stability of the printed circuit 120 due to impurities.

[0030] The mounting part 200 has a mounting hole 210, and the light source module 300 is disposed in the mounting hole 210. That is to say, the light source module 300 is embedded in the mounting part 200. In this case, the light source module 300 and the mounting part 200 share the thickness space of the lighting fixture, so that the light source module 300 does not occupy the extra thickness space of the lighting fixture, avoiding the large thickness of the lighting fixture due to the sequential stacking of the light source module 300 and the mounting part 200, thereby enabling the lighting fixture to be made thinner.

[0031] Meanwhile, the light source module 300 is electrically connected to the printed circuit 120. Specifically, the mounting hole 210 can be a through hole, through which part of the light source module 300 can pass directly to the printed circuit 120 for electrical connection, avoiding the need to add other electrical connection components in the lighting fixture, so as to realize the electrical connection between the light source module 300 and the printed circuit 120.

[0032] In the lighting fixture disclosed in this application embodiment, a substrate 100 and a mounting portion 200 are disposed opposite to each other. A printed circuit 120 is provided on the first surface 130 of the substrate 100 facing the mounting portion 200. A light source module 300 is disposed in a mounting hole 210 and is electrically connected to the printed circuit 120. In this solution, the printed circuit 120 is directly disposed on the substrate 100, avoiding the need for a separate circuit board device in the lighting fixture. This allows the substrate 100 to achieve a multi-purpose effect, thereby simplifying the structure of the lighting fixture, reducing the number of components, and facilitating the assembly and disassembly of the lighting fixture by workers.

[0033] Meanwhile, the light source module 300 and the mounting part 200 share the thickness space of the lighting fixture, so that the light source module 300 does not occupy additional thickness space of the lighting fixture. This avoids the lighting fixture having a large thickness due to the sequential stacking of the light source module 300 and the mounting part 200, thus allowing the lighting fixture to be made thinner. Therefore, this solves the problems of excessive thickness and inconvenient assembly and disassembly of the lighting fixture.

[0034] Specifically, the lighting fixture may have a housing, and the substrate 100 has a second side opposite to the first side 130, at least part of the second side forming one of the outer surfaces of the housing, in order to simplify the structure of the lighting fixture and reduce the number of parts of the lighting fixture.

[0035] Furthermore, the substrate 100 and the mounting portion 200 constitute the housing of the lighting fixture, and at least one of the substrate 100 and the mounting portion 200 constitutes the outer surface of the housing, so as to further simplify the structure of the lighting fixture and reduce the number of parts of the lighting fixture.

[0036] Optionally, both the substrate 100 and the mounting portion 200 can be flat, and the substrate 100 and the mounting portion 200 are attached to each other to further reduce the thickness of the lighting fixture. Furthermore, to enable a thinner lighting fixture, the thickness of the substrate 100 can optionally be 0.5 mm to 1.5 mm, and the mounting portion 200 can be flat, with a thickness of 2.8 mm to 5.5 mm. In this case, the thickness of the lighting fixture is 3.3 mm to 7 mm, which undoubtedly allows for a smaller overall thickness.

[0037] The thickness of the substrate 100 can be determined based on its size, that is, the surface area of ​​the substrate 100. When the substrate 100 is larger, its thickness also needs to be larger to meet the strength requirements of the lighting fixture. Of course, the material of the substrate 100 can also determine its thickness. For example, for the same size, the thickness of an iron substrate 100 can be less than that of an aluminum substrate 100.

[0038] As mentioned above, the substrate 100 can be of various types. Optionally, the substrate 100 can be an aluminum plate. Aluminum has a low density, which makes the substrate 100 lighter, thus reducing the weight of the lighting fixture and enabling it to be thinner and lighter. At the same time, aluminum plates are lightweight yet strong, preventing the lighting fixture from easily deforming or being damaged. Furthermore, the thin aluminum plate also facilitates heat dissipation, resulting in excellent heat dissipation performance for the lighting fixture.

[0039] Furthermore, the mounting part 200 can be an aluminum composite panel (ACP), which is relatively lightweight and has high strength, further enabling the lighting fixture to be made thinner and lighter. ACPs are typically included in single-sided and multi-sided applications. Optionally, the mounting part 200 can be a single-sided ACP, with one side of the ACP facing away from the substrate 100. This makes the outer surface of the lighting fixture harder, preventing unevenness caused by impacts and improving the overall neatness of the fixture's appearance. At the same time, compared to multi-sided ACPs, single-sided ACPs are thinner, lighter, and cheaper.

[0040] Specifically, the aforementioned lighting fixtures can be wall lamps, ceiling lamps, table lamps, and pendant lamps, etc. When the lighting fixture is a wall lamp, it may also include a mounting bracket, which is installed on the wall. The base plate 100 or the mounting part 200 can be connected to the mounting bracket, either by snap-fit ​​or by threaded connection, thereby achieving the effect of a wall lamp. When the lighting fixture is a ceiling lamp, the base plate 100 can be connected to the ceiling by bolts. When the lighting fixture is a table lamp, it may also include a table lamp holder, and the lighting fixture can be rotatably connected to the table lamp holder, allowing the lighting angle to be adjusted.

[0041] In the case of a chandelier, the lighting fixture may optionally include a suspending structure 400 and a suspension wire 500. The substrate 100 may have a suspending hole 110. The substrate 100 and the mounting portion 200 can form a receiving space 600. The suspending hole 110 can communicate with the receiving space 600. At least a portion of the suspending structure 400 can be located within the receiving space 600 and is positioned relative to the substrate 100 in the suspending direction. The suspension wire 500 is connected to the suspending structure 400, thus making the lighting fixture a chandelier. In this solution, at least a portion of the suspending structure 400 can be located within the receiving space 600, preventing the lighting fixture from being too large due to the suspending structure 400 being entirely outside the receiving space 600. This improves the space utilization rate of the lighting fixture, resulting in a compact structure.

[0042] In this embodiment, the substrate 100 and the mounting portion 200 can form a receiving space 600. Specifically, the mounting portion 200 may have a clearance hole 220, and the substrate 100 and the clearance hole 220 can form the receiving space 600. It is more convenient to have a clearance hole 220 on the mounting portion 200.

[0043] The aforementioned suspension line 500 can be a steel wire suspension line or a suspension rope. Optionally, the suspension line 500 can be an electrical connection line for a lighting fixture, so that the electrical connection line can both provide power to the lighting fixture and suspend the lighting fixture, thus achieving a dual-purpose effect.

[0044] Typically, electrical connection wires include single-core wires and multi-core wires. A single-core wire is a wire with one current path, while a multi-core wire is a wire with at least two current paths, such as the neutral and live wires in home wiring. If the neutral and live wires are in one wire, it is called a multi-core wire; if they are separate, with each being a separate wire, it is called a single-core wire. Optionally, the electrical connection wire can be a single-core wire. The mounting structure 400 can include a first mounting part 410, which can be located within the receiving space 600 and engages with the substrate 100 in the mounting direction. The first mounting part 410 passes through the mounting hole 110 and can be electrically connected to the printed circuit 120. The electrical connection wire can be connected to the first mounting part 410 and is electrically connected. The electrical connection cable can be used to both suspend the lighting fixture via the first lifting part 410 and to connect to the printed circuit board 120, avoiding complex wiring for the lighting fixture's electrical connections, thus simplifying the fixture's structure and reducing design difficulty. This configuration is suitable for situations where the electrical connection cable is a single-core wire.

[0045] Specifically, the first lifting section 410 may include a body section 411 and a limiting section 412. The limiting section 412 is located within the accommodating space 600. One end of the body section 411 can be connected to the limiting section 412, and the other end of the body section 411 can pass through the lifting hole 110. The limiting section 412 is in a limiting engagement with the base plate 100 in the lifting direction. This specific lifting method makes the structure of the first lifting section 410 simple, the lifting reliable, and the disassembly and assembly convenient for workers.

[0046] As described above, the first lifting part 410 is electrically connected to the printed circuit 120. Specifically, the lifting structure 400 may further include an electrical connection part 420, which may be located between the limiting section 412 and the substrate 100. The first lifting part 410 can be electrically connected to the printed circuit 120 through the electrical connection part 420, which facilitates the connection between the first lifting part 410 and the printed circuit 120, thereby facilitating operation by the operator. Specifically, the electrical connection part 420 may conduct a conductive coil.

[0047] To prevent leakage current in the lighting fixture, which could cause the substrate 100 and mounting portion 200 to become energized and potentially lead to electric shock, in an optional embodiment, the mounting structure 400 may further include an insulating portion 430. The substrate 100 may have a printed circuit area and an insulating area. The printed circuit 120 is disposed in the printed circuit area. The first mounting portion 410 is electrically connected to the printed circuit 120, and the insulating portion 430 may be disposed between the first mounting portion 410 and the insulating area. The insulating portion 430 prevents the first mounting portion 410 from contacting the substrate 100, thus preventing the substrate 100 from becoming energized and preventing electric shock, thereby improving the safety performance of the lighting fixture.

[0048] To further improve the reliability of the lighting fixture hoisting via the suspension line 500, the hoisting structure 400 may optionally include a second hoisting part 440. The second hoisting part 440 may be connected to the first hoisting part 410, and the electrical connection line may be in upper limit engagement with the second hoisting part 440 in the hoisting direction. In this embodiment, the suspension line 500 is connected to both the first hoisting part 410 and the second hoisting part 440, meaning that the suspension line 500 can hoist the lighting fixture via both the first hoisting part 410 and the second hoisting part 440, preventing the lighting fixture from falling if either fails, thereby improving the reliability of the lighting fixture hoisting.

[0049] The second lifting part 440 can be snapped or welded to the first lifting part 410. Optionally, the outer wall of the first lifting part 410 can have a first threaded section, and the second lifting part 440 can have a connecting hole 441. An electrical connection wire can pass through the connecting hole 441 and connect to the first lifting part 410. The connecting hole 441 can have a second threaded section, and the first threaded section can be threadedly connected to the second threaded section, so that the second lifting part 440 and the first lifting part 410 are threadedly connected. This makes the second lifting part 440 and the first lifting part 410 detachably connected, which is convenient for workers to carry out maintenance and disassemble and assemble the lighting fixture.

[0050] As described above, the electrical connection cable and the second lifting part 440 can be engaged in a limiting fit in the lifting direction. Specifically, the end of the connection hole 441 away from the first lifting part 410 can have a limiting surface 442, and the electrical connection cable has a limiting protrusion 510. The limiting protrusion 510 and the limiting surface 442 are engaged in a limiting fit in the lifting direction. This configuration is simple and reliable, convenient for operators to install, and at the same time, avoids connecting the electrical connection cable to the second lifting part 440, thus avoiding inconvenience for operators during disassembly and assembly.

[0051] Typically, electrical connection wires include single-core and multi-core wires. To avoid short circuits, multi-core wires cannot be electrically connected to the first hoisting part 410. Therefore, please refer to [the relevant documentation / reference]. Figure 2 Optionally, the electrical connection wire can be a multi-core wire. The sling structure 400 can include a first sling part 410 and a second sling part 440. The first sling part 410 can have a through hole 413, and the second sling part 440 can have a connection hole 441. The electrical connection wire passes through the through hole 413 and the connection hole 441 and is electrically connected to the printed circuit 120, so that the electrical connection wire is directly electrically connected to the printed circuit 120, avoiding short circuits caused by the multi-core wire being electrically connected to the first sling part 410, thereby improving the stability and safety of the electrical connection of the lighting fixture.

[0052] Optionally, the first lifting part 410 is partially located within the receiving space 600 and engages with the substrate 100 in the lifting direction. The second lifting part 440 is connected to the first lifting part 410. The end of the connecting hole 441 facing away from the first lifting part 410 may have a limiting surface 442. The electrical connection wire may have a limiting protrusion 510, which can engage with the limiting surface 442 in the lifting direction. In the specific lifting process, the limiting protrusion 510 suspends the second lifting part 440, the second lifting part 440 suspends the first lifting part 410, and the first lifting part 410 suspends the substrate 100, thereby realizing the lifting of the lighting fixture. This lifting structure 400 is relatively simple and reliable.

[0053] Furthermore, an insulating layer can be provided on the surface of the first lifting part 410 and the surface of the second lifting part 440. This insulating layer can make the first lifting part 410 and the second lifting part 440 insulated from each other, preventing the first lifting part 410 and the second lifting part 440 from becoming energized due to leakage of the lighting fixture, thereby preventing the substrate 100 and the mounting part 200 from becoming energized, preventing electric shock accidents to users, and thus improving the safety performance of the lighting fixture.

[0054] Please refer to this again. Figure 3 In one optional embodiment, the light source module 300 may include LED beads 310. The LED beads 310 may be disposed on the first surface 130 and electrically connected to the printed circuit 120. The LED beads 310 can be directly disposed on the printed circuit 120, facilitating fabrication, simplifying the structure, and reducing design complexity for designers. Specifically, the LED beads 310 may be LED (Light Emitting Diode) beads to reduce the power consumption of the lighting fixture.

[0055] Furthermore, the light source module 300 may also include a light control element 320 and a light-emitting mask 330. The LED chip 310 may be disposed on the first surface 130 and electrically connected to the printed circuit 120. The light control element 320 may be disposed in the mounting hole 210, and the light-emitting mask 330 may be disposed on the side of the light control element 320 facing away from the substrate 100. The light control element 320 enables the light emitted by the LED chip 310 to illuminate the desired location as much as possible, thereby improving the lighting effect of the lighting fixture.

[0056] Specifically, the light control element 320 can be a lens, a light guide plate, or a reflector, and the light emitting mask 330 can be a diffuser plate, so that the light emitted by the lamp bead 310 can be diffused more evenly to the position to be illuminated under the diffusion effect of the light emitting mask 330, thereby further improving the lighting effect of the lighting fixture. Of course, the light emitting mask 330 can also be a light guide element, etc.

[0057] Furthermore, the surface of the light-emitting mask 330 facing away from the lamp bead 310 can be coplanar with the surface of the mounting part 200 facing away from the substrate 100, so that the appearance of the lighting fixture is flatter and simpler, thereby improving the user experience.

[0058] To further enhance the lighting effect of the lighting fixture, the lighting fixture may optionally include at least two sets of light source modules 300, which are spaced apart on the substrate 100. The mounting portion 200 may be flat and has at least two mounting holes 210 spaced apart, each of which corresponds to one of the at least two sets of light source modules 300. The presence of at least two sets of light source modules 300 undoubtedly enhances the lighting effect of the lighting fixture, thereby improving the user experience.

[0059] Specifically, multiple mounting holes 210 can be arranged around the clearance hole 220. That is, multiple mounting holes 210 are arranged in an array around the clearance hole 220 so that the lighting fixture can be suspended in the middle of the lighting fixture. This makes the lighting fixture more evenly stressed after suspension, thereby improving the suspension effect of the lighting fixture and ultimately enhancing the suspension stability of the lighting fixture.

[0060] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0061] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
