[0002] Subway panel lights, serving as rectangular light sources, have gradually replaced traditional lighting fixtures and are appearing in various lighting applications. These applications not only require multiple independent rectangular LED lights, but also often necessitate the combination and splicing of multiple rectangular LED lights according to specific lighting needs.

[0003] Current LED lighting splicing methods generally adopt fixed unidirectional splicing installation, such as splicing horizontally or vertically, but cannot be spliced ​​in both directions; at the same time, the splicing components used are complex in structure, causing inconvenience to end customers; and if LED lighting needs to be spliced, it is not possible to splice the LED lighting quickly.

[0004] Therefore, there is an urgent need for a splicing method that is both stable and easy to disassemble. Summary of the Invention

[0005] Based on existing technology, the purpose of this utility model is to provide LED lighting unit and combined LED lighting, aiming to solve the problems of poor versatility of LED lighting splicing components and complicated splicing operations in the existing technology.

[0006] To achieve the above-mentioned technical objectives, the technical solutions adopted in the embodiments of this utility model include:

[0007] In a first aspect, this utility model provides an LED lighting unit body, which includes a housing and end caps, with two end caps respectively covering both ends of the housing; the end caps are connected to the ends of the housing by fasteners, and the end caps are provided with connecting protrusions, and the connecting protrusions are provided with connecting portions for splicing two adjacent LED lighting units.

[0008] Furthermore, at least two of the connecting protrusions are arranged symmetrically on the end cap.

[0009] Furthermore, the housing is detachably connected to a support frame for mounting LED lamp units, and the two ends of the support frame are respectively connected to both sides of the housing along its length.

[0010] The support frame and the connecting protrusion are both located on the same side of the LED lamp unit.

[0011] Secondly, this utility model embodiment provides a combined LED lamp, which includes at least two of the above-mentioned LED lamp units and a connecting component; adjacent two LED lamp units are connected laterally or longitudinally through the connecting component to combine and connect multiple LED lamp units to form a whole.

[0012] Furthermore, the connecting assembly includes a connector and a limiting member.

The connector is connected to the connecting part of the end cap through the cooperation of the connecting post and the limiting member, so that the connecting assembly is connected to the end cap provided at one end of at least one LED lighting unit.

[0013] The connecting part is a connecting hole.

[0014] Furthermore, the connector is a connecting block, and a connecting post is connected to the connecting block.

[0015] Furthermore, the connector is a connecting strip, and the connecting strip is provided with two connecting posts; each connecting post is provided with at least one slot, and the limiting member is engaged in the slot.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] like Figures 1 to 6 As shown in the figure, this solution provides a combined LED luminaire, which includes two first connecting components 5 and two LED luminaire units 1.

[0038] Reference Figure 1 , Figure 6 As shown, two LED lighting units 1 are connected by two first connecting components 5; one end of one LED lighting unit 1 is connected to one end of the other LED lighting unit 1 through the two first connecting components 5, so that the two adjacent LED lighting units 1 are horizontally connected through the first connecting components 5, so as to combine the two LED lighting units 1 into a whole.

[0039] Therefore, multiple LED lighting units 1 can be connected in series at one end of the LED lighting unit 1, so that the LED lighting unit 1 can be expanded laterally, and then multiple LED lighting units 1 can be combined to form long strip-shaped combined LED lighting fixtures of various lengths.

[0040] like Figure 6 As shown, the end caps 4 of the two LED lamp units 1 are fitted together, and the connecting holes 42 of the two end caps 4 are aligned so that the connecting post 52 on the connecting block 51 is inserted into the connecting hole 42 of the end cap 4, and the limiting member 53 is inserted into the slot 54 provided in the connecting post 52; so that the connecting protrusions 41 of the two end caps 4 are connected together through the first connecting component 5, thereby the two end caps 4 are fitted together, and the two LED lamp units 1 are laterally connected through the first connecting component 5.

[0041] like Figure 2-4 As shown, the specific structure of the LED lighting unit 1 is as follows:

[0042] like Figure 2 , 3 As shown, the LED lighting unit 1 includes a housing 11, a power supply assembly 2, a support frame 3, and end caps 4. The housing 11 has connecting grooves 12 on both sides along its length. The two end caps 4 are respectively covered and connected to both ends of the housing 11 by fasteners 7. The support frame 3 for mounting the LED lighting unit 1 is detachably connected to the housing 11, and the two ends of the support frame 3 are respectively connected to both sides of the housing 11 along its length. The power supply assembly 2 is detachably connected to the housing 11 by a fixing bracket, and the two ends of the fixing bracket are detachably connected to both sides of the housing 11 along its length.

[0043] Among them, reference Figure 3 As shown, the two ends of the support frame 3 are detachably connected to both sides of the housing 11 along its length direction by fasteners 7, and the fasteners 7 are connected in the connecting groove; both ends of the support frame 3 are provided with at least one hook part 32, and the hook part 32 is engaged in the connecting groove.

[0044] In this embodiment, the support frame 3 is provided with a hook portion 32, which is located on one side of the fastener 7. Both ends of the support frame 3 are detachably connected to the fastener 7 on both sides of the housing 11 along its length direction through the hook portion 32.

[0045] This solution uses hook parts 32 to insert the hook parts 32 at both ends of the support frame 3 into the connecting groove 12, so that the support frame 3 can move along the length direction of the connecting groove, thereby adjusting the position of the support frame 3 on the housing 11; at the same time, the fasteners 7 are connected in the connecting groove, and both ends of the support frame 3 are connected to both sides of the housing 11 along its length direction.

[0046] In addition, by setting up the support frame 3, the support frame 3 is fixedly connected to the fixed frame by the fastener 7, thereby fixing the LED lighting unit 1 to the fixed frame by the support frame 3, thus completing the fixed installation of the LED lighting unit 1.

[0047] like Figure 4 As shown, the specific structure of end cap 4 is as follows:

[0048] The end cap 4 is provided with a countersunk hole 43, which is used to embed and place the fastener 7; the two end caps 4 are fastened to the two ends of the housing 11 by the fastener 7, and the end cap 4 is provided with a connecting protrusion 41 for connecting with the first connecting component 5; the connecting protrusion 41 is provided with a connecting part for splicing two adjacent LED lamp units 1.

[0049] At least two connecting protrusions 41 are symmetrically arranged on the end cover 4, and the support frame 3 and the connecting protrusions 41 are both located on the same side of the LED lamp unit 1; the connecting part is the connecting hole 42.

[0050] like Figure 5 , 6 As shown, the specific structure of the first connecting component 5 is as follows:

[0051] Reference Figure 5 As shown, the first connecting component 5 includes a connector and a limiting component 53. The connector is provided with a connecting post 52, and a slot 54 is provided at the end of the connecting post 52 away from the connector. The limiting component 53 is engaged in the slot 54.

[0052] The connector is a connecting block 51, and a connecting post 52 is connected to the connecting block 51. The connecting post 52 has a slot 54. The connecting block 51 and the limiting member 53 cooperate to form a clamping space. The connecting protrusions 41 of the two end caps 4 are interference-fitted with the clamping space, so that the connecting block 51 and the limiting member 53 cooperate to clamp each other on both sides of the two connecting protrusions 41.

[0053] It should be noted that in this embodiment, the limiting member 53 is an E-type retaining ring, and the fastener 7 is a regular screw, a self-tapping screw, or an internal hex screw, etc.

[0054] like Figure 6 As shown, the end caps 4 of two LED lamp units 1 are attached together, and the connecting holes 42 of the two end caps 4 are aligned so that the connecting post 52 on the connecting block 51 is inserted into the connecting hole 42 of the end cap 4, and the limiting member 53 is inserted into the slot 54 of the connecting post 52. Through the setting of the connecting block 51 and the limiting member 53, the connecting block 51 and the limiting member 53 cooperate with each other to clamp on both sides of the two attached connecting protrusions 41. The connecting protrusions 41 of the two end caps 4 are connected together through the first connecting component 5, so that the two end caps 4 are attached together, and the two LED lamp units 1 are laterally connected through the first connecting component 5.

[0055] The modular LED light in this embodiment features end caps 4 at both ends of its rectangular LED lights. It can be easily spliced ​​and fixed using the first connecting component 5, allowing for direct splicing into various straight-line structures without the need for custom-designed splicing structures. This novel splicing method is simple, requiring only basic components to achieve the splicing function. The rectangular LED light design allows for combination and splicing into various strip configurations according to requirements, and also enables stacking. Each light fixture can be individually disassembled for easy maintenance.

[0056] Example 2

[0057] See Figure 7-8 as well as Figure 1 As shown, the present invention provides a second embodiment of a combined LED lamp, which includes two second connecting components 6 and two LED lamp units 1.

[0058] Reference Figure 1 and Figure 8 As shown, two LED lighting units 1 are connected by two second connecting components 6. The two LED lighting units 1 are placed side by side, and both ends of one LED lighting unit 1 are connected to both ends of the other LED lighting unit 1 through the two second connecting components 6, so that the two adjacent LED lighting units 1 are longitudinally connected through the second connecting components 6, so as to combine and connect multiple LED lighting units 1 to form a whole.

[0059] The connecting component of the second embodiment is largely the same as that of the connecting component of the first embodiment. The difference between the connecting component of the second embodiment and the connecting component of the first embodiment is that the second connecting component 6 includes a connector and a limiting member 53. The connector is provided with two connecting posts 52, and a slot 54 is opened at the end of the connecting post 52 away from the connector. The limiting member 53 is engaged in the slot 54. The limiting member 53 is an E-type retaining spring.

[0060] Reference Figure 7 As shown, the connector is a connecting strip 56, and the connecting strip 56 is provided with two connecting posts 52. The connecting strip 56 is provided with an abutting protrusion 55, which abuts against the housing 11. The abutting protrusion 55 is used to restrict the movement of the two housings 11 when the two LED lamp units 1 are connected together. The two connecting posts 52 are both located on the same side of the connecting strip 56. Each connecting post 52 is provided with a slot 54, and the limiting member 53 is engaged in the slot 54. The connecting strip 56 and the two limiting members 53 cooperate to form two clamping spaces.

[0061] Reference Figure 8 As shown, the end caps 4 of two LED lamp units 1 are arranged side by side, and the two side by side end caps 4 are connected together by a second connecting component 6. The two ends of the second connecting component 6 are respectively connected to the connecting protrusions 41 of the two end caps 4. The two connecting posts 52 of the second connecting component 6 are respectively inserted into the connecting holes 42 of the two end caps 4, and the connecting posts 52 are engaged with the limiting member 53. The two clamping spaces of the connecting strip 56 are respectively interference-fitted with the connecting protrusions 41 of the two end caps 4, so that the connecting strip 56 and the limiting member 53 are respectively clamped at the two ends of the connecting protrusions 41 of the end caps 4.

[0062] Two LED lamp units 1 are placed side by side, with the two connecting posts 52 of the connecting block 51 inserted into the connecting holes 42 of the two end caps 4, and the limiting member 53 inserted into the slot 54 of the connecting post 52. The connecting block 51 and the two limiting members 53 cooperate to clamp the connecting protrusions 41 of the two end caps 4 on both sides. The second connecting component 6 is connected to the two end caps 4, and the two LED lamp units 1 are longitudinally connected through the second connecting component 6.

[0063] Therefore, multiple LED lighting units 1 can be connected in parallel on one side of the length direction of the LED lighting unit 1, so that the LED lighting unit 1 can be extended longitudinally, and then multiple LED lighting units 1 can be combined to form rectangular combined LED lighting fixtures of various widths.

[0064] The modular LED light in this embodiment features end caps 4 at both ends of its rectangular LED lights, allowing for easy splicing and fixing with the aid of the second connecting component 6. It can be directly spliced ​​into various rectangular structures without the need for custom-designed splicing structures. This novel splicing method is simple, requiring only basic components to achieve the splicing function. The rectangular LED light design allows for various rectangular configurations to be combined and spliced ​​according to requirements, and can also be stacked. Each light fixture can be individually disassembled for easy maintenance.

[0065] Example 3

[0066] See Figure 9 , 10 As shown, the present invention provides a third embodiment of a combined LED lamp, which includes a connecting component and four LED lamp units 1; the configuration of the combined LED lamp is that the LED lamp units 1 are combined in two parallel and two series, and the four LED lamp units 1 are connected by the connecting component.

[0067] The connecting component of the third embodiment is substantially the same as that of the connecting component of the second embodiment. The difference between the connecting component of the third embodiment and the connecting component of the second embodiment lies in that, referring to... Figure 9 , 10 As shown, the third connecting component 8 includes a connector and a limiting component 53. The connector has two connecting posts 52, and two slots 54 are opened at the end of the connecting post 52 away from the connector. The limiting component 53 is engaged in one of the slots 54. The limiting component 53 is an E-type retaining spring.

[0068] Reference Figure 9 , 10As shown, the connector is a connecting strip 56, and the connecting strip 56 is provided with two connecting posts 52. The connecting strip 56 is provided with an abutting protrusion 55, which abuts against the housing 11. The abutting protrusion 55 is used to restrict the movement of the two housings 11 when the two LED lamp units 1 are connected together. The two connecting posts 52 are both located on the same side of the connecting strip 56. Each connecting post 52 is provided with two slots 54, and the limiting member 53 is engaged in one of the slots 54. The connecting strip 56 and the two limiting members 53 cooperate to form two clamping spaces.

[0069] When the limiting member 53 is engaged in the slots 54 at different positions on the connecting post 52, the connecting strip 56 and the limiting member 53 cooperate to form clamping spaces of different sizes, and different numbers of connecting protrusions 41 are clamped in the clamping spaces.

[0070] In this embodiment, four LED lamp units 1 are connected in a two-parallel and two-series combination via a connecting component. The third connecting component 8 is located in the middle of the four LED lamp units 1. Two LED lamp units 1 are connected to each end of the third connecting component 8.

[0071] Reference Figure 10 As shown, the specific connection structure of the four LED lighting unit 1 is as follows:

[0072] The modular LED lighting fixture uses a third connecting component 8 to combine four LED lighting units 1 in two series and two parallel configurations. The four LED lighting units 1 are connected in series and then in parallel. The end caps 4 of the two series-connected LED lighting units 1 fit together. The connecting posts 52 at both ends of the third connecting component 8 are connected to two fitting end caps 4. The connecting posts 52 pass through the connecting holes 42 of the two end caps 4. The limiting member 53 is inserted into the slot 54 at the end of the connecting post 52 away from the connecting strip 56. This results in two fitting connecting protrusions 41 in the clamping space. The connecting strip 56 and the limiting member 53 cooperate to clamp the two fitting connecting protrusions 41 on both sides. As a result, two series-connected LED lighting units 1 are connected to both ends of the third connecting component 8.

[0073] In addition, the two fitting end caps 4 have a connecting protrusion 41 on the side away from the third connecting component 8 connected together by the first connecting component 5. The specific connection method of the first connecting component 5 is the connection method of the connecting component in Embodiment 1, and this connection method will not be described again.

[0074] Reference Figure 10As shown, the combined LED lamp, consisting of four LED lamp units 1, is connected at both ends by a third connecting component 8. The end caps 4 of two parallel LED lamp units 1 are arranged side by side. The connecting posts 52 at both ends of the third connecting component 8 are connected to an end cap 4, and the connecting posts 52 pass through the connecting holes 42 of one end cap 4. The limiting member 53 is inserted into the slot 54 of the connecting post 52 near the end of the connecting strip 56, so that a connecting protrusion 41 is provided in the clamping space. This allows the connecting strip 56 to cooperate with the limiting member 53 and be clamped on both sides of the connecting protrusion 41 of the end cap 4, thereby connecting an LED lamp unit 1 at both ends of the third connecting component 8.

[0075] In addition, the two ends of the combined LED lamp can also be connected together by the second connecting component 6. The specific connection method of the second connecting component 6 is the connection method of the connecting component in Embodiment 2, which will not be described in detail here.

[0076] It should be noted that the LED lighting unit 1 is connected horizontally or vertically through multiple connecting components, and the multiple LED lighting unit 1 is expanded in a matrix to combine and connect the multiple LED lighting unit 1 to form a whole; wherein, the multiple connecting components 5 are one, two or more of the first connecting component 5, the second connecting component 6 and the third connecting component 8.

[0077] Therefore, multiple LED lighting units 1 can be connected in series and parallel in sequence, allowing the LED lighting units 1 to expand horizontally and vertically, and thus multiple LED lighting units 1 can be combined to form various matrix LED lighting units 1.

[0078] The modular LED light in this embodiment features end caps 4 at both ends of its rectangular LED lights. It can be easily assembled and fixed using the first connecting component 5, the second connecting component 6, and the third connecting component 8, allowing for direct assembly into various rectangular structures without the need for custom-designed splicing structures. This novel splicing method is simple, requiring only basic components to achieve the splicing function. The rectangular LED light design allows for various rectangular configurations to be combined and spliced ​​according to requirements, and allows for stacking and splicing. Each light fixture can be individually disassembled for easy maintenance.

[0079] Example 4

[0080] See Figure 11 , 12As shown, this utility model provides a fourth embodiment of a combined LED lamp, which includes a connecting component and two LED lamp units 1; the configuration of the combined LED lamp is that the two LED lamp units 1 are connected in a staggered manner, and the two LED lamp units 1 are connected by the connecting component; the two LED lamp units 1 are arranged in parallel and staggered.

[0081] The connecting component of the fourth embodiment is substantially the same as that of the connecting component of the second embodiment, except that the connecting component of the fourth embodiment differs from that of the connecting component of the second embodiment in that: (Refer to...) Figure 11 , 12 As shown, the fourth connecting component 9 includes a connector and a limiting component 53. The connector has two connecting posts 52, and a slot 54 is opened at the end of the connecting post 52 away from the connector. The limiting component 53 is engaged in the slot 54. The limiting component 53 is an E-type retaining spring.

[0082] Reference Figure 11 As shown, the connector is a connecting strip 56, and the connecting strip 56 is provided with two connecting posts 52. The connecting strip 56 is provided with an abutting protrusion 55, which abuts against the housing 11. The abutting protrusion 55 is used to restrict the movement of the two housings 11 when the two LED lamp units 1 are connected together. The two connecting posts 52 are respectively provided on both sides of the connecting strip 56. Each connecting post 52 is provided with a slot 54, and the limiting member 53 is engaged in the slot 54. The connecting strip 56 and the two limiting members 53 cooperate to form two clamping spaces.

[0083] Reference Figure 12 As shown, two LED lamp units 1 are arranged in parallel and staggered. The end caps 4 at one end of the two LED lamp units 1 are connected together by the fourth connecting component 9. The two sides of the connecting strip 56 are connected to the end caps 4 of the two LED lamp units 1 respectively by connecting posts 52. The connecting posts 52 on both sides of the connecting strip 56 are inserted into the connecting holes 42 of the two end caps 4. The connecting posts 52 are engaged with the limiting member 53. The two clamping spaces provided by the connecting strip 56 are respectively interference-fitted with the connecting protrusions 41 of the two end caps 4, so that the connecting strip 56 and the limiting member 53 are respectively clamped at both ends of the connecting protrusions 41 of the end caps 4.

[0084] Two LED lamp units 1 are placed side by side with a staggered arrangement, so that the two connecting posts 52 of the connecting strip 56 are respectively inserted into the connecting holes 42 of the two end caps 4, and the limiting member 53 is inserted into the slot 54 provided in the connecting post 52; so that the connecting block 51 and the two limiting members 53 cooperate with each other to clamp on both sides of the connecting protrusion 41 provided in the two end caps 4; the fourth connecting component 9 is connected to the two end caps 4 respectively, and then the two LED lamp units 1 are connected side by side with a staggered arrangement through the fourth connecting component 9.

[0085] Therefore, multiple LED lighting units 1 can be connected in parallel and staggered on one side of the length direction of the LED lighting unit 1, so that the LED lighting unit 1 can be expanded longitudinally and staggered, and then multiple LED lighting units 1 can be combined to form various shapes of combined LED lighting fixtures.

[0086] In summary, the connecting component in this invention, since the rectangular LED lamp has end caps 4 at both ends, can be spliced ​​and fixed by means of the connecting component; the connecting component is fixed on the end of the LED lamp unit 1, and with the cooperation of the connecting strip 56 or the connecting block 51 and the limiting member 53, the connecting component is connected to the connecting protrusion 41 of the end cap 4; the end caps 4 of the two LED lamp units 1 are fixed together, thereby completing the splicing between the LED lamp units 1; so that two adjacent LED lamp units 1 can be connected laterally or longitudinally through the connecting component, so as to combine and connect multiple LED lamp units 1 to form a whole.

[0087] In addition, the LED lighting unit 1 can be spliced ​​and fixed by multiple connecting components, and can be directly spliced ​​into various combined configurations. The combined LED lighting unit is selected from any one or more of the first connecting component 5, the second connecting component 6, the third connecting component 8 and the fourth connecting component 9. Through the combination of multiple connecting components, various splicing methods such as straight line, double line, matrix, and staggered hollow type between LED lighting units 1 can be completed. The splicing operation is simple, does not require special customization according to splicing requirements, and has strong versatility.
