Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0032] This embodiment relates to a lamp, see reference Figures 1-3The system includes a lampshade 100, a control circuit board 200, a light-emitting element 300, and a driving power supply assembly. The lampshade 100 has a light-transmitting surface 121 on one side; the control circuit board 200 is mounted inside the lampshade 100; the light-emitting element 300 is mounted on the control circuit board 200; the light emission direction of the light-emitting element 300 faces the light-transmitting surface 121; the driving power supply assembly is mounted on the control circuit board 200; and the control circuit board 200, the light-emitting element 300, and the driving power supply assembly are electrically connected. Compared to traditional lamps where the light-emitting element 300 is located inside the lampshade 100 while the driving power supply assembly is located outside the lampshade 100, placing both the light-emitting element 300 and the driving power supply assembly on the control circuit board 200 inside the lampshade 100 reduces the installation and disassembly costs associated with separately installing the driving power supply assembly, the light-emitting element 300, and the wiring between them. It also facilitates installation and disassembly, resulting in a more compact overall size for the lamp. Furthermore, both the driving power supply assembly and the light-emitting element 300 are housed within the lamp cover 100, increasing protection for the driving power supply assembly and making the overall system safer and more reliable. Specifically, the light-emitting element 300 is an LED lamp. In some embodiments, the light-emitting element 300 may also be other devices capable of emitting light.

[0033] Furthermore, referring to Figures 3-4 The drive power supply assembly includes: a surge suppressor 410, a capacitor 420, a main control chip 430, a rectifier bridge 440, and a fuse 450; the surge suppressor 410, capacitor 420, main control chip 430, rectifier bridge 440, and fuse 450 are electrically connected. A wire hole is provided on the side wall of the lampshade 100 for one end of a wire to pass through and electrically connect to the control circuit board 200. The surge suppressor 410 protects electrical equipment from damage caused by power surges (voltage surges). The rectifier bridge 440 converts AC power to DC power to meet the power requirements of subsequent circuits. The fuse 450 protects the circuit for safety.

[0034] In this embodiment, refer to Figures 1-2 The lampshade 100 includes a base plate 110 and a cover 120. The base plate 110 is used for assembling the control circuit board 200; the cover 120 is placed on the base plate 110 and has a light-transmitting surface 121. When the cover 120 is placed on the base plate 110, the bottom surface of the cover 120 and the bottom surface of the base plate 110 are on the same horizontal plane. The base plate 110 and the control circuit board 200 are assembled using screws or other fasteners to ensure that the control circuit board 200 is securely mounted on the base plate 110. The light-transmitting surface 121 of the cover 120 is made of frosted material, making the light emitted by the light-emitting element 300 softer and more uniform, improving the lighting effect. When the cover 120 is placed on the base plate 110, the bottom surface of the cover 120 and the bottom surface of the base plate 110 are on the same horizontal plane (see attached diagram). Figure 1The central horizontal axis (A) means that the cover 120 completely covers one side of the control circuit board 200, the drive power supply assembly, the light-emitting element 300, and the base plate 110, providing higher protection and preventing dust or dirt accumulation in the gaps. It also reduces light leakage and improves the overall lighting effect. When circuit maintenance is required, only the cover 120 needs to be removed, eliminating the need to disassemble the entire lamp, thus reducing maintenance complexity. Furthermore, the outer surface of the cover 120 is curved, making it easier for users to grip and enhancing the overall aesthetics.

[0035] In this embodiment, the cover 120 and the base plate 110 are detachably assembled for easy circuit maintenance. Furthermore, the side wall of the base plate 110 is provided with an outwardly protruding latching part 510, and the inner wall of the cover 120 is provided with a snap-fit ​​groove 520 that mates with the latching part 510, so as to achieve quick assembly and disassembly.

[0036] In this embodiment, refer to Figures 4-6 The lamp also includes an assembly part 610 and a magnetic component 620. One end of the assembly part 610 is fixedly mounted on the bottom surface of the base plate 110, and the other end extends away from the base plate 110. The assembly part 610 has a hollow structure 611. The base plate 110 has a through hole 111 communicating with the hollow structure 611. One end of the magnetic component 620 is assembled between the assembly part 610 and the base plate 110, and the other end passes through the through hole 111 and the hollow structure 611, protruding from the side of the assembly part 610 away from the base plate 110. The magnetic component 620 and the assembly part 610 work together to achieve convenient assembly and disassembly. Specifically, the magnetic component 620 is a magnet. In some embodiments, the magnetic component 620 can also be a magnet.

[0037] Furthermore, the magnetic attractor 620 is T-shaped. (Refer to...) Figures 5-7The lamp also includes a first limiting member 710 and a second limiting member 720. One end of the first limiting member 710 is disposed on the side of the base plate 110 facing away from the assembly part 610, and the free end extends toward the center of the through hole 111. One end of the second limiting member 720 is disposed on the inner wall of the assembly part 610, and the other end extends toward the center of the hollow structure 611, cooperating with the first limiting member 710 to prevent the magnetic component 620 from falling off. The cooperation between the first limiting member 710 and the second limiting member 720 ensures the stable assembly of the magnetic component 620, preventing it from falling off from one side of the control circuit board 200 or the bottom side of the base plate 110. During the assembly of the magnetic 620, the magnetic 620 is first inserted into the base plate 110 from the side near the control circuit board 200 until one end of the magnetic 620 is inserted between the first limiting member 710 and the second limiting member 720. At this time, the bottom surface of the free end of the first limiting member 710 abuts against the top surface of the magnetic 620, and the top surface of the second limiting member 720 abuts against the side of the magnetic 620 facing the second limiting member 720. The other end of the magnetic 620 passes through the through hole 111 and the hollow structure 611 and is exposed on the side of the assembly part 610 away from the base plate 110.

[0038] Specifically, refer to Figures 7-8 The first limiting member 710 includes an extension 711 and a bending portion 712. One end of the extension 711 is fixedly disposed on the side of the base plate 110 facing away from the assembly portion 610, and the free end extends vertically upward. One end of the bending portion 712 is fixedly disposed on the free end of the extension 711, and the other end extends horizontally toward the center of the through hole 111. The bending portion 712 is made of an elastic material and is used to prevent the magnetic component 620 from falling off toward the control circuit board 200. The bending portion 712 is made of an elastic material such as hard rubber or plastic, and has space for elastic deformation. When the magnetic component 620 is assembled, the bending portion 712 is squeezed. After the magnetic component 620 is assembled, the bending portion 712 returns to its original shape to limit the magnetic component 620.

[0039] In some embodiments, refer to Figures 3-4 One end of the cover 120 is provided with a mounting part 800 having a mounting hole. The bottom surface of the mounting part 800 and the bottom surface of the magnetic component 620 are on the same horizontal plane. The mounting part 800 allows users to easily pass screws and other fasteners through the mounting hole for further reinforcement. Positioning the bottom surface of the mounting part 800 and the bottom surface of the magnetic component 620 on the same horizontal plane ensures that both the mounting part 800 and the magnetic component 620 can simultaneously contact the mounting surface (such as a wall or cabinet surface) during installation, preventing either the mounting part 800 or the magnetic component 620 from failing to contact the mounting surface and thus preventing them from achieving proper co-fixing.

[0040] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
