Abstract
Description
Technical Field
[0001] This application relates to the field of lighting equipment technology, specifically to a modular luminaire and connector assembly. Background Technology
[0002] Linear lights, as a common linear lighting device, are widely used in office lighting and other fields. In actual installation, multiple linear lights are often connected end to end to splice them together, also known as cascading, in order to form a continuous lighting line and enhance the overall structural integrity.
[0003] Currently, the common method for splicing lighting fixtures usually requires disassembling the end caps or light-emitting faceplates of the fixtures to expose the internal connection structure before mechanical connections and electrical wiring are made. This splicing method is cumbersome, requires a high level of skill from installers, and is prone to damaging fixture components during repeated disassembly and reassembly. Furthermore, this structure often makes it difficult to ensure precise alignment at the joints, easily resulting in noticeable gaps that affect both light efficiency and aesthetics. Utility Model Content
[0004] The main technical problem this application addresses is the inconvenience of splicing existing linear lights.
[0005] According to a first aspect, one embodiment provides a modular lighting fixture, comprising: A first lamp body and a second lamp body. The first lamp body has a plug-in portion at one end, and the second lamp body has a receiving portion at one end for slidingly engaging with the plug-in portion. The plug-in portion and the receiving portion extend in the same direction and are perpendicular to the direction in which the first lamp body and the second lamp body are joined. The plug-in part can slide and snap-fit along the extension direction of the receiving part, so that the first lamp body and the second lamp body are fixedly connected. An electrical connector is provided on the first lamp body and the second lamp body for electrically connecting the first lamp body and the second lamp body.
[0006] In some embodiments, the insertion part is a slider, and the receiving part is a groove that cooperates with the slider.
[0007] In some embodiments, the slider has an L-shaped cross-section perpendicular to its extension direction; And / or, the groove extends from one side of the second lamp body to the opposite side.
[0008] In some embodiments, one of the insertion portion and the receiving portion is provided with an elastic buckle, and the other is provided with a locking portion that cooperates with the elastic buckle. The elastic buckle is used to engage with the locking portion when the insertion portion slides along the receiving portion to a predetermined position.
[0009] In some embodiments, the outer periphery of the elastic buckle is arc-shaped, and the snap-fit portion is an arc-shaped groove.
[0010] In some embodiments, the modular lighting fixture includes a connector assembly, which includes a first component and a second component. The first component is fixedly connected to the end of the first lamp body, and the second component is fixedly connected to the end of the second lamp body. The insertion portion is disposed on the first component, and the receiving portion is disposed on the second component.
[0011] In some embodiments, the modular lighting fixture includes a fixing member disposed at one end of the receiving portion extending in the direction of extension, and used to be fixedly connected to both the first lamp body and the second lamp body simultaneously.
[0012] In some embodiments, the modular lighting fixture includes a sealing member, which has the receiving portion or the plug portion and is used to connect to the end of the first piece or the second piece.
[0013] In some embodiments, the second component is further provided with a second insertion portion, and the first component is further provided with a second receiving portion that slides with the second insertion portion, wherein the second receiving portion extends in the same direction as the receiving portion.
[0014] According to a second aspect, one embodiment provides a connector assembly, which is the connector assembly in the splicable lighting fixture described in any of the above embodiments.
[0015] According to the splicable lamps of the above embodiments, the ends of the first lamp body and the second lamp body are respectively provided with plug-in parts and receiving parts, and the extension direction of the two parts is perpendicular to the splicing direction of the lamps. This allows the two lamp bodies to be spliced simply by sliding perpendicular to the splicing direction, avoiding the need to disassemble all lamps at the rear end when the lamp body in the middle position fails. The sliding snap-fit structure composed of the plug-in part and the receiving part can realize the alignment, guidance and positioning functions between the two lamp bodies, making the splicing process of the linear lights simpler and faster.

Detailed Implementation
[0018] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0019] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.
[0020] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0021] Currently, multiple light fixtures in a modular lighting system are generally connected in series. If a group of light fixtures in the middle malfunctions, it is necessary to remove the remaining light fixtures at the rear of the fixture before repairing it, which makes repairs difficult. This is especially true for some concealed installation scenarios, such as wall gaps or inside ceilings, and it can also easily damage the surrounding decoration structure.
[0022] Furthermore, existing light fixtures lack precise positioning clips or slots between the lamp bodies, making it easy for gaps to appear at the joints during installation, leading to light leakage. Installers must repeatedly adjust the fixture positions to ensure a smooth fit. If the installation surface, such as a wall or ceiling, is uneven, the assembled light fixtures will appear misaligned, further widening the gaps.
[0023] To solve the above technical problems, a sliding snap-fit structure can be set at the end of the lamp body. The sliding snap-fit structure can realize the alignment, guidance and positioning functions when the lamp body is spliced. If the extension direction of the sliding snap-fit structure is set to be perpendicular to the splicing direction of the lamp body, then when repairing a lamp body, it can be directly slid off without disassembling the other lamp bodies.
[0024] like Figures 1-6 As shown, one embodiment provides a modular lighting fixture, including: a first lamp body 100, a second lamp body 200, and an electrical connector 300 disposed on the first lamp body 100 and the second lamp body 200. The first lamp body 100 and the second lamp body 200 are the basic units of the modular lighting fixture. The lamp body may include a housing, a cover, and a light-emitting module disposed between the housing and the cover. The electrical connector 300 may specifically include a male plug and a female plug, which are respectively disposed on the first lamp body 100 and the second lamp body 200 to achieve electrical connection between them.
[0025] The first lamp body 100 has a plug-in portion 411 at its end, and the second lamp body 200 has a receiving portion 421 at its end for sliding engagement with the plug-in portion 411. It should be understood that the plug-in portion 411 at the end of the first lamp body 100 includes the following two situations: the lamp body itself has a plug-in portion 411; or the end of the lamp body is fixedly connected to other components, and the components have a plug-in portion 411.
[0026] In this embodiment, the modular lighting fixture further includes a connector assembly 400, which includes a first component 410 and a second component 420. The first component 410 is fixedly connected to the end of the first lamp body 100, and the first component 410 is provided with a plug-in portion 411. The second component 420 is fixedly connected to the end of the second lamp body 200, and the second component 420 is provided with a receiving portion 421. The first lamp body 100 and the first component 410, and the second lamp body 200 and the second component 420 can be fixed together using fasteners such as bolts.
[0027] The insertion part 411 and the receiving part 421 extend in the same direction and are perpendicular to the direction in which the first lamp body 100 and the second lamp body 200 are joined. The direction in which the first lamp body 100 and the second lamp body 200 are joined refers to the direction from the first lamp body 100 to the second lamp body 200. Figures 1-2 As shown in the figure, as an example, the splicing direction of the first lamp body 100 and the second lamp body 200 is the left-right direction, and the extension direction of the insertion part 411 and the receiving part 421 is the up-down direction. Specifically, when splicing the second lamp body 200, the second lamp body 200 is pushed upwards from bottom to top. In other embodiments, the extension direction of the insertion part and the receiving part can also be the front-back direction.
[0028] The fact that the extension direction of the plug-in part 411 and the receiving part 421 is perpendicular to the splicing direction means that when disassembling a lamp body in the lamp fixture, it is not necessary to disassemble the other lamp bodies at its rear end; only the lamp body needs to be disassembled. This reduces the difficulty of lamp fixture maintenance and helps to improve maintenance efficiency.
[0029] The insertion part 411 can slide and engage along the extension direction of the receiving part 421 to fix the first lamp body 100 and the second lamp body 200 in a fixed connection. The sliding engagement structure composed of the insertion part 411 and the receiving part 421 enables the alignment, guidance, and positioning functions between the two lamp bodies, making the splicing process of the linear lights simpler and faster. Specifically, the structure that allows the insertion part 411 to slide along the receiving part 421 makes the splicing process of the first lamp body 100 and the second lamp body 200 more convenient. The engagement and fixation of the insertion part 411 and the receiving part 421 ensures that the relative positions of the first lamp body 100 and the second lamp body 200 are fixed after they are spliced and aligned, making it less prone to slippage, while also providing the splicer with force or sound feedback indicating that the alignment has been achieved.
[0030] In some embodiments, such as Figures 3-4 As shown, the insertion part 411 is a slider, and the receiving part 421 is a groove that mates with the slider. The slider has an L-shaped cross-section perpendicular to its extension direction. The structure of the slider and the groove is relatively simple, making assembly convenient. By setting the slider to an L-shape and fixing it relative to the groove along the splicing direction, the connection strength between the first lamp body 100 and the second lamp body 200 is enhanced, making it less likely for the first lamp body 100 and the second lamp body 200 to wobble or have gaps.
[0031] The groove extends from one side of the second lamp body 200 to the opposite side. It's important to note that since the groove is located on the second piece 420, the side of the second lamp body 200 should be understood as the plane containing the side of the second lamp body 200; that is, the groove extends from the plane containing one side of the second lamp body 200 to the plane containing the opposite side. With this arrangement, the groove extends through the entire second piece 420, making it easier for the slider to slide into the groove and facilitating the assembly process.
[0032] In some embodiments, the second member 420 is further provided with a second insertion portion 422, and the first member 410 is further provided with a second receiving portion 412 that slides with the second insertion portion 422. The second receiving portion 412 extends in the same direction as the receiving portion 421. Specifically, the insertion portion 411 and the second receiving portion 412 are arranged at intervals on the first member 410, and the snap-fit portion and the second insertion portion 422 are arranged at corresponding intervals on the second member 420. The insertion portion 411 and the second insertion portion 422 have the same structure, and the snap-fit portion and the second snap-fit portion have the same structure, that is, the structures of the first member 410 and the second member 420 for mutual connection are symmetrically arranged.
[0033] The symmetrical structure of the first piece 410 and the second piece 420 enables a sliding snap-fit connection on both sides, so that when the first piece 410 and the second piece 420 are spliced, the stress points are symmetrically distributed on both sides, which significantly improves the stability of the connection and effectively prevents twisting or warping that may occur in the length direction after splicing.
[0034] In some embodiments, such as Figure 2 , Figures 3-4 As shown, one of the insertion part 411 and the receiving part 421 is provided with an elastic buckle 4211, and the other is provided with a locking part that cooperates with the elastic buckle 4211. The elastic buckle 4211 is used to engage with the locking part when the insertion part 411 slides along the receiving part 421 to a predetermined position. Specifically, the elastic buckle 4211 can be a protrusion provided on the groove wall of the slide, and the locking part can be a groove 4111 provided on the slider.
[0035] The elastic buckle 4211 is designed to engage with the snap-fit part, so that the plug part 411 can automatically engage and lock when it slides to the predetermined position of the receiving part 421. This makes the connection between the first piece 410 and the second piece 420 more secure and reliable, and can effectively prevent the lamp body from loosening due to vibration or its own weight during use.
[0036] The outer periphery of the elastic snap fastener 4211 can be set to an arc shape, and correspondingly, the engaging part is an arc-shaped groove 4111. The cooperation between the arc-shaped outer periphery of the elastic snap fastener 4211 and the arc-shaped groove 4111 provides a smooth guide surface for the snap fastening and disengagement. This makes the engaging action smoother and reduces assembly resistance. At the same time, due to the self-centering characteristic of the arc surface, it allows the snap fastener to be guided into accurate position even when there are slight assembly deviations.
[0037] In some embodiments, such as Figure 5 As shown, the modular lighting fixture includes a fixing member 500, which is disposed at one end of the receiving portion 421 in the extending direction and is used to fixably connect with both the first lamp body 100 and the second lamp body 200. Specifically, the fixing member 500 includes a plate 510 and an elastic portion 520 disposed on one side of the plate 510. The elastic portion 520 can engage with the protrusions on the first lamp body 100 and the second lamp body 200, thereby enhancing the connection between the first lamp body 100 and the second lamp body 200 and preventing the lamp body from slipping due to its own weight or other factors.
[0038] In some embodiments, such as Figures 7-9 As shown, the splicable lighting fixture includes a sealing member 600, which has a receiving part or a plug-in part. The receiving part is adapted to the plug-in part 411 on the first member 410, and the plug-in part is adapted to the receiving part 421 on the second member 420. The sealing member 600 is used to connect to the end of the first member 410 or the second member 420. Specifically, for the lighting fixture, the two lamp bodies located at both ends of the lighting fixture can be sealed at the ends using the sealing member 600. The first member 410 and the second member 420 can be fixed to the lamp bodies located at both ends respectively, and then the two sealing members 600 are connected to the first member 410 and the second member 420 respectively to achieve sealing at both ends of the lighting fixture.
[0039] like Figure 10 As shown, in a specific embodiment, the modular lighting fixture consists of only one lamp body. A first component and a second component are fixed to both ends of the lamp body, and two sealing components 600 are provided to seal both ends of the lamp body. For this modular lighting fixture, after removing the sealing components 600, it can be modularly connected to other lamp bodies.
[0040] According to the second aspect, one embodiment provides a connector assembly whose structure is the same as that of the connector assembly 400 in the splicable lighting fixture described in any of the above embodiments, and will not be repeated here.
[0041] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
