[0032] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0033] refer to Figures 1-8 This embodiment provides a modular lighting fixture, including: multiple elongated LED lamp bodies 1, multiple electrical connection connectors 2, and a power connector 3.

[0034] Electrical connectors 2 and power connectors 3 are available in two-prong and three-prong configurations, and can also be configured with four-prong, five-prong, etc., as needed. For example, six long, strip-shaped LED light bodies 1 can form a hexagonal unit using five three-prong electrical connectors 2 and one three-prong power connector 3. Each of the six fixed corners of the hexagon has an empty cavity at each connector 2 or power connector 3, allowing for further expansion. Once the desired shape is achieved, two-prong electrical connectors 2 can be used on the hexagonal units at the edges.

[0035] The structure of power connector 3 is described in detail below:

[0036] The power connector 3 includes: a connector head cover 31, a connector lower cover 32, two conductive parts 33, a conductive part fixing seat 34, and an external terminal 35;

[0037] The upper cover 31 and the lower cover 32 of the connector each include an upper mounting base 31 and a lower mounting base 321 located at the center, and at least two connecting arms 312 and 322 respectively arranged in a rotationally symmetrical manner along the circumference of the upper mounting base 31 and the lower mounting base 321.

[0038] A partition 323 is provided between the lower mounting base 321 and the connecting arm 322 of the connector lower cover 32, and the partition 323 is provided with a clearance opening 324; the lower mounting base 321 extends upward from the axis to form a guide post 325; the conductive element 33 includes a central portion 331 coaxial with the guide post 325, a hollow cylindrical extension portion 332 arranged symmetrically along the central portion 331, and a conductive sheet 333 electrically connected to the external terminal 35. The number of hollow cylindrical extension portions 332 is M, and the number of connecting arms 322 is N, so M=N-1; one side of the external terminal 35 is electrically connected to the conductive sheet 333, and the other side is provided with a first conductive pin 351 for connecting the power line 4.

[0039] The conductive component fixing seat 34 is provided with a first through hole 341 and a second through hole 342 along the extension direction of the guide post 325. The hollow cylindrical extension portions 332 of the two conductive components 33 are respectively placed in the first through hole 341 and the second through hole 342. The conductive component fixing seat 34 is engaged at the clearance opening 324.

[0040] The upper and lower covers of the connector are joined together to form a cavity for inserting the elongated LED lamp body 1 into the connecting arms 312 and 322.

[0041] Taking the three-prong power connector 3 as an example, two chambers are used to insert the long strip-shaped LED lamp body 1, and the other chamber is used to insert the power cord 4. The difference between the three-prong electrical connector 2 and the power connector 3 is that the conductive piece 333 is removed and replaced with three hollow cylindrical extension parts 332.

[0042] In this embodiment, the clearance opening 324 is a U-shaped groove.

[0043] To facilitate the fixing of the electrical connector 2 and the power connector 3, the lower cover 32 of the connector extends a lug 326 in the part corresponding to the lower mounting base 321, and the lug 326 is provided with a mounting hole.

[0044] In addition, the elongated LED lamp body 1 includes a housing 11, a plug 12, a light source board 13, and a driving module 14;

[0045] The outer casing 11 is divided into a first chamber and a second chamber along its thickness direction. The light source board 13 and the drive module 14 are respectively placed in the first chamber and the second chamber. The plug 12 is provided with a groove 121 that mates with the conductive component fixing seat 34. A second conductive pin 122 is provided in the groove 121 to mate with the hollow cylindrical extension 332. When the elongated LED lamp body 1 is inserted into the chamber, the second conductive pin 122 can be inserted into the hollow cylindrical extension 332 to form a stable electrical connection. The lamp body of the elongated LED lamp body 1 is then mechanically connected to the inner wall of the chamber.

[0046] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
