Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and more specifically, to a grounded lighting fixture. Background Technology

[0002] In the field of modern home lighting, as people's pursuit of personalized home environments increases, lamps have gradually become common household lighting fixtures and are widely used.

[0003] Existing simple lighting fixtures often use a combination of metal springs and metal mounting plates for grounding. However, when the installation environment is unstable, such as when animals chew on the wiring, or when there is water leakage from the ceiling, or when the lighting fixture is to be expanded to include additional functional components such as junction boxes, grounding becomes difficult using the conventional method. This makes the junction box difficult to handle, inconvenient for both installation and grounding of the lighting fixture, and significantly increases the difficulty of grounding and assembling the components, as well as the amount of grounding wire required. Such lighting fixtures are difficult to install and ground reliably. Therefore, how to achieve safe and reliable grounding for lighting fixtures with junction boxes and other components has become a problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a grounded lamp with the advantages of convenient grounding, strong adaptability and wide applicability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a grounded lamp, comprising: an insulating shell for mounting a foundation; A junction box is installed on top of the insulating housing; The lamp body is installed at the bottom of the insulating outer casing; A metal sheet is disposed inside the insulating shell and extends through the upper and lower sides of the insulating shell for grounding. The metal sheet has through holes. The control circuit module is installed inside the insulating housing; The LED driver is installed inside the insulating housing and located below the control circuit module; A fastener is inserted through the through hole to connect the metal sheet to the junction box and the lamp body.

[0006] In one embodiment, the insulating housing includes a housing and a bottom cover, the bottom cover being detachably connected to an opening in the housing; The metal sheet penetrates the housing and the bottom cover, and the control circuit module is installed at the top inside the housing.

[0008] In one embodiment, the insulating housing is provided with a through post that penetrates the housing and the bottom cover, the through post being located between the metal sheet and the inner wall of the housing; The fastener passes through the through hole and is connected to the through post.

[0009] In one embodiment, a hook extends downward from the top of the housing for engaging the control circuit module; A fixing post extends downward from the top inside the housing. The bottom of the fixing post abuts against the surface of the LED driver to restrict the vertical movement of the LED driver.

[0010] In one embodiment, the junction box includes a hinged cover and a housing, the hinged cover being hinged to the opening of the housing, and the bottom of the housing being connected to the top of the housing and one end of the metal sheet.

[0011] In one embodiment, a conductive contact piece is provided at the bottom of the box body. The conductive contact piece is connected to the through hole through the fixing member, so as to make the conductive contact piece abut against the top of the metal sheet.

[0012] In one embodiment, the top of the lamp body has an opening, which is connected to the through hole through the fastener, so that the lamp body abuts against the bottom of the metal sheet.

[0013] In one embodiment, a lamp buckle is provided on each side of the lamp body. The lamp buckle includes a mounting member, a spring, and a retaining member.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," 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 connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] A grounded lighting fixture, such as Figure 1-2 As shown, the device includes an insulating housing 1, a junction box 2, a lamp body 3, a metal plate 4, a control circuit module 5, an LED driver 6, and a fixing component. The insulating housing 1 serves as the mounting base; the junction box 2 is installed on top of the insulating housing 1; the lamp body 3 is installed at the bottom of the insulating housing 1; the metal plate 4 is disposed inside the insulating housing 1 and extends through both the top and bottom sides of the insulating housing 1 for grounding, and has a through hole 41; the control circuit module 5 is installed inside the insulating housing 1; the LED driver 6 is installed inside the insulating housing 1 and located below the control circuit module 5; the fixing component passes through the through hole 41 to connect the metal plate 4 to the junction box 2 and the lamp body 3.

[0024] With the above design, the advantage of this embodiment is that the insulating shell 1 can be assembled with different lamps equipped with junction boxes 2, and the entire lamp can be grounded. In practical applications, the junction box 2 can be connected through the top through hole 41 of the metal plate 4 to ensure the firmness of the lamp assembly. At the same time, the excellent conductivity of the metal plate 4 allows the junction box 2 to be grounded through it. The insulating shell 1 and the junction box 2 do not need to be equipped with too many grounding wires to avoid redundancy. The same applies to the lamp body 3, making the entire lamp assembly firm and reliable, and grounding convenient. The through hole 41 can be set at various parts of the metal plate 4 according to the needs of the actual installation process, such as the top of the metal plate 4, etc., which will not be described in detail here.

[0025] Meanwhile, due to its excellent insulation properties, the insulating shell 1 can also provide electrical isolation between the junction box 2 and the lamp body 3. If the insulation layer of the wires inside the junction box 2 is damaged or becomes damp, the insulating shell 1 can prevent current from forming a circuit through the lamp body 3, avoiding sparks, overheating, or even fires caused by short circuits, effectively blocking leakage paths and reducing the risk of electric shock. Furthermore, its mechanical protection and compliant design take into account safety, reliability, and service life, and its advantages are particularly significant in complex environments or long-term high-load operation scenarios.

[0026] like Figure 2-3 As shown, the insulating housing 1 includes a housing 11 and a bottom cover 12, with the bottom cover 12 detachably connected to the opening of the housing 11. A metal sheet 4 penetrates the housing 11 and the bottom cover 12, and the control circuit module 5 is installed at the top inside the housing 11. In this embodiment, the housing 11 can be a seamless structure, effectively preventing the intrusion of moisture, dust, and corrosive gases, thus improving the protection level of the housing 11 (moisture, etc., generally fall from top to bottom due to gravity), preventing internal electrical components from malfunctioning due to contamination or moisture, and extending the equipment's lifespan. The bottom cover 12 can be detachably connected via a quick-connect structure such as a snap-fit, allowing access to internal components (such as the control circuit module 5) without disassembling the entire insulating housing 1, significantly reducing the time cost of installation, maintenance, or component replacement, and is especially suitable for scenarios requiring future maintenance.

[0027] like Figure 1-2 and Figure 4 As shown, the longitudinal section of metal sheet 4 is one of I-shaped, L-shaped, and C-shaped.

[0028] In this embodiment, the metal sheet 4 is C-shaped. This has the advantage that when the surfaces of the junction box 2 and the lamp body 3 that contact the insulating shell 1 are flat planes, the upper and lower ends of the C-shaped metal sheet 4 can be connected through-hole to the bottom of the junction box 2 and the top of the lamp body 3 respectively via fasteners (e.g., the fasteners are vertically positioned relative to the top of the insulating shell 1 to achieve a through-hole connection). While grounding via the metal sheet 4, a secure assembly is also achieved.

[0029] When the surfaces of the junction box 2 and lamp body 3 that contact the insulating shell 1 are not flat, the upper and lower ends of the I-shaped metal piece 4 can pass through (or penetrate) the bottom of the junction box 2 and the top of the lamp body 3, respectively. A fastener can then be used to snap the connection through the through hole 41 (e.g., the fastener is placed horizontally relative to the top of the insulating shell 1 to achieve snap-fit). Similarly, grounding is achieved through the metal piece 4, while also ensuring a secure assembly. When the metal piece 4 is designed in an L-shape, it takes into account that the surfaces of the junction box 2 and lamp body 3 that contact the insulating shell 1 can be either flat or uneven. The L-shape combines the through-connection and snap-fit ​​methods of the C-shaped and I-shaped metal pieces 4, allowing the entire lamp to be securely assembled.

[0030] like Figure 1 and Figure 3 As shown, the insulating outer shell 1 has a through post 13 that penetrates the shell 11 and the bottom cover 12. The through post 13 is located between the metal sheet 4 and the inner wall of the shell 11; the through hole 41 of the fixing member is connected to the through post 13. With the above design, the advantage of this embodiment is that the through post 13 is connected to the top and bottom of the insulating outer shell 1, allowing different junction boxes 2 and lamp bodies 3 to be fixedly installed at the through point using fixing members, thus making the assembly of the entire lamp more secure. Furthermore, the two through holes 41 of the metal sheet 4 can also cooperate with the through point of the through post 13, allowing the junction box 2 and lamp body 3 to be securely assembled with the insulating outer shell 1 using the metal sheet 4, making the entire lamp more reliable. In this utility model, the fixing member can be of various types, such as a combination of nuts and bolts, etc., which will not be elaborated here.

[0031] like Figure 3 As shown, a hook 14 extends downward from the top inside the housing 11 for engaging the control circuit module 5; a fixing post 15 extends downward from the top inside the housing 11, with the bottom of the fixing post 15 abutting against the surface of the LED driver 6 to restrict the movement of the LED driver 6 in the vertical direction.

[0032] Hook 14 and fixing post 15 extend downward from the top and are connected to control circuit module 5 and LED driver 6 respectively, forming a "suspended" support. The weight of control circuit module 5 and LED driver 6 is transferred to the main body of insulating shell 1 through the top, reducing the load pressure on the bottom detachable structure. In particular, when the bottom needs to be disassembled, it can prevent the modules from loosening due to changes in the bottom position.

[0033] like Figure 5 As shown, the junction box 2 includes a hinged cover 21 and a box body 22. The hinged cover 21 is hinged to the opening of the box body 22. The bottom of the box body 22 is connected to the top of the housing 11 and one end of the metal plate 4. The hinged connection of the hinged cover 21 to the opening of the box body 22 forms a "flip-type entrance," allowing the junction box 2 to be opened without completely disassembling the cover. This facilitates quick connection of power cords, inspection of wiring terminals, or replacement of internal components, making it particularly suitable for one-handed operation in confined spaces within ceilings and reducing installation time.

[0034] A conductive contact piece 221 is provided at the bottom of the housing 22. The conductive contact piece 221 is connected to the through hole 41 through a fixing member, so that the conductive contact piece 221 abuts against the top of the metal sheet 4. An opening 31 is provided at the top of the lamp body 3. The opening 31 is connected to the through hole 41 through a fixing member, so that the lamp body 3 abuts against the bottom of the metal sheet 4.

[0035] In the above configuration, the two major functions of electrical conduction and mechanical positioning are integrated through the metal sheet 4, the conductive contact piece 221 and the opening 31, so as to achieve reliable multi-dimensional connection with the fewest parts and design, and meet the safety requirements (electrical connection, grounding and insulation) of lighting equipment.

[0036] like Figure 6 As shown, lamp buckles 7 are provided on both sides of the lamp body 3. Each lamp buckle 7 includes a mounting member 71, a spring 72, and a stop member 73. One side of the mounting member 71 is mounted on the side of the lamp body 3, and the other side is hinged to one side of the mounting member 71 by the spring 72.

[0037] Based on the above design, the advantage of this embodiment lies in the elastic deformation characteristics of the spring 72, which allows the lamp holder 7 to switch between "fitted" and "unfurled" states by manual pressing. This can be applied to embedded installation scenarios, such as when the lamp is installed in the ceiling. Pushing the lamp into the ceiling mounting hole compresses the spring 72, causing the abutment 73 to fit against the lamp. Once in place, the spring 72 returns to its original position, and the abutment 73 automatically unfolds and fits tightly against the wall (such as a suspended ceiling layer) within the ceiling, requiring no additional tools or complex fixing steps, significantly improving installation efficiency. Disassembly is simple: just press the abutment 73 to compress the spring 72, and the lamp can be easily removed without damaging the ceiling structure, facilitating later maintenance, light source replacement, or circuit inspection.

[0038] Junction box 2 and lamp body 3 are made of metal. Metal plate 4 serves as a conductive connector, directly connecting the metal junction box 2 and lamp body 3 to form a continuous conductor. When the lamp housing becomes energized due to a fault, metal plate 4 ensures that the grounding current is quickly conducted to the ground through a low-impedance path, preventing the human body from being subjected to dangerous voltage upon contact.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
